Task Description

PIDNS13 fix

Please find a patch to fix the sigsegv error on pidns13.c on containers. Signed-off-by: Veerendra C <veerendrac@in.ibm.com>.

V4L2 test enhancements

Today I released version 0.3 of v4l-test, see http://v4l-test.sourceforge.net/ for details. I also updated the LTP tree, and I attached the two files in this email. The first file is a patch against ltp-full-20081231. The second file is a tar.gz which contains the binary image files which are part of the original V4L2 API specification, revision 0.24. Signed-Off-By: Németh Márton <nm127@freemail.hu>.

AUTOCONF for INOTIFY03

Introduce autoconf to inotify03.c. Signed-off-by: Masatake YAMATO <yamato@redhat.com>.

AUTOCONF error reporting info

The way to report a bug about configure: Introducing autoconf still causes a troble. Shooting the trouble may not be so difficult. However, some information is needed. I'll write them on INSTALL file. Signed-off-by: Masatake YAMATO <yamato@redhat.com>.

UNZIP fix for Soft Links

Convert hardlinks to softlinks in testcases/commands/unzip/Makefile: Kamalesh Babulal <kamalesh@linux.vnet.ibm.com> wrote: The make install of the testcases/commands/ unzip fails, when the ltp sources are mounted on different filesystem other than /tmp, because the hardlinks are created by the testcase Makefile. This patches converts the hardlinks to softlinks. Signed-off-by: Kamalesh Babulal <kamalesh@linux.vnet.ibm.com>. CAI Qian <caiqian@cclom.cn> replied: Are you really want to change the above two soft links to hard links? I do not see it helps to fix your problem, and it will leave broken links after "make clean". Kamalesh Babulal <kamalesh@linux.vnet.ibm.com> replied: Thanks for the review. I am resending the patch with the changes you have recommended. Signed-off-by: Kamalesh Babulal <kamalesh@linux.vnet.ibm.com>.

mmapstress03 fix: return back MAP_FIXED flag to mmap

There is a testcase in mmapstress03, which checks, that we can't mmap 2Gb-512Kb of RAM at address 0x7ff80000. But if host has > 2Gb of RAM+swap - it's valid operation: mmap maps 2Gb of ram at some other address and returns no errors. For correct working of this testcase we should add MAP_FIXED flag to mmap. Signed-Off-By: Dmitry Guryanov <dguryanov@parallels.com>.

mmapstress03 fix: on x86_64:

There is a testcase in mmapstress03, which tries to mmap 2Gb-4Kb at address 0x7ffff000 and checks it returns error and errno is set to ENOMEM. But such mmap is possible on x86_64. So lets tune size and address to more suitable for 64-bit architectures. Signed-Off-By: Dmitry Guryanov <dguryanov@parallels.com>.

madvise03 fix

madvice03: report TCONF instead of TWARN on old kernels: If kernel is too old for executing this test, we should report TCONF for exit code will be 0. Signed-Off-By: Dmitry Guryanov <dguryanov@parallels.com>.

endian_switch01 fix

Nancy<nancydreaming@gmail.com> reported:Case "endian_switch01" FAIL on IBM Power 6 machine. The case failed on IBM JS22, p570 and p550. Is that the case bug or the OS bug? Thank you!. Subrata Modak <subrata@linux.vnet.ibm.com> replied: This will fail for all POWER machines which are not P6 & above, and, for all other archs. However, for other archs, it will throw you appropriate message like: $./testcases/bin/endian_switch01 endian_switch01 1 CONF : This system does not support running of switch() syscall. In P6 (and above), even it will fail if the kernel is not 2.6.26 & above. The support for this syscall was added only from then. Please see: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=745a14cc264b1832c638e41812e0cb04328b2db1. If you are running 2.6.26 on p6, then we need to investigate why this is failing, else, i would prefer to merge the following patch for avoiding to test in systems where the switch() support is not available at the first place itself. Signed-Off-By: Subrata Modak <subrata@linux.vnet.ibm.com>,

SELINUX reference Policy updates

This patch adds RHEL4 and RHEL5 detection to refpolicy Makefile and fixes policy compilation errors on RHEL5 introduced by the bounds test policy. Signed-off-by: Ramon de Carvalho Valle <rcvalle@linux.vnet.ibm.com>.

AUTOCONF for PIDNS14 & PIDNS16

checking sys/capability.c for pidns14 and pidns16: this patch adds "sys/capability.c" checking for pidns14 and pidns16 testcases using autoconf support. Signed-off-by: Edjunior B. Machado <emachado@linux.vnet.ibm.com>.

TCORE build fix for non x86 systems

Edjunior Barbosa Machado <emachado@linux.vnet.ibm.com> wrote: in a ppc64 machine running SLES11 RC1, I'm trying to build the December 2008 LTP release (ltp-full-20081231) but it fails on "make". Mike Frysinger <vapier@gentoo.org> replied: tcore only works on x86 systems ... building /running on other systems makes no sense. Subrata Modak <subrata@linux.vnet.ibm.com> answered: Mike, Then the following Patch will be needed: Signed-Off-By: Subrata Modak <subrata@linux.vnet.ibm.com>.

VMSPLICE01 syntax Fix

A while back I had submitted an LTP patch for the vmsplice01 test case (sent on 03/27/2008). However, the code I see in the vmsplice01.c file now is not what the patch contains. Please find below the correction against the latest ltp release : Signed-off by: Vinay Sridhar <vinay@linux.vnet.ibm.com>.

NLS Device Drivers Build fixes for 2.6.25

Update kernel/device-drivers/nls test for 2.6.25: the attached patch makes the ltp/testcases/kernel/device-drivers/nls testsuite compileable under Linux kernel 2.6.25. Currently the test_nls_base() crashes with 2.6.25, but without calling that function the module loads and unloads cleanly. This can be a base for checking what is going wrong with nls. Signed-off-by: Márton Németh <nm127@freemail.hu>.

Release of GCOV Patches for 2.6.28

MESSAGE QUEUE NAMESPACE Test Addition

Sending the new patch along with the batch file to run the tests. Also made small modifications in the mesgq_nstest.c to fix: a) the warnings on tst_exit(). b) to remove the global var. And to return correct error num in the batch file runipcnstest.sh. Signed-off-by: Veerendra C <veerendra@in.ibm.com>.

TCORE build fix for non x86 systems

Avoiding build failures on ppc64, adding proper FLAG definitions and improving a bit of LTP specific stuff. Signed-Off-By: Subrata Modak <subrata@linux.vnet.ibm.com>. set flags properly and just use implicit make rules. Mike Frysinger <vapier@users.sourceforge.net>

BLOCK Device Drivers Tests addition

I attached a preliminary testsuite for testing linux/block/genhd.c. The goal of this test suite is to check whether using block device is stable enough. A lot of test suites under ltp/testcases/kernel/device-drivers are based on the usage of block device so it shall work relayable. Note that the module under test is different in case of ltp/testcases/kernel/device-drivers/tbio/kernel_space testsuite. Signed-off-by: Márton Németh <nm127@freemail.hu>.

NLS Device Drivers documentation updates

[2nd Updates for kernel/device-drivers/nls test for 2.6.25]: Németh Márton initially wrote: the attached patch makes the ltp/testcases/kernel/device-drivers/nls testsuite compileable under Linux kernel 2.6.25. Currently the test_nls_base() crashes with 2.6.25, but without calling that function the module loads and unloads cleanly. This can be a base for checking what is going wrong with nls. Signed-off-by: Márton Németh <nm127@freemail.hu>. Subrata Modak replied: Thanks Németh for the patch. I tested the build on my machine 2.6.27, x86_64. I have merged this Patch. However, i would request you to send me another patch containing the following information: 1) Kernel config options to be enabled & any special library(s) to be installed to allow these tests to be built/run on kernel(s) > 2.6.25 in the following README: http://ltp.cvs.sourceforge.net/viewvc/ltp/ltp/README, 2) Then, http://ltp.cvs.sourceforge.net/viewvc/ltp/ltp/testcases/kernel/device-drivers/nls/README, should contain information to build/install/run these tests. Since these are device drivers tests, and will be executed through insmod, etc, can we have a script which automates these steps and reports error in loading/unloading of modules as such. I think it can be a very small script as well. Németh Márton responded by: I added some descriptions in the mentioned READMEs. However, I would wait adding an automated shell script because the tests fails on my x86_32 system with 2.6.28, and for example "rmmod nlsTest" reports "ERROR: Module nlsTest is in use". The real problem is, however, that the one of the test case already caused NULL pointer exception. I also don't have any easy solution to report only the nlsTest output to the user other than first running "dmesg -c" and then load nlsTest.ko. After the module was loaded the "dmesg" will only show the output of the testsuite. The drawback is that the user will loose the first part of his/her "dmesg" in this way. Signed-Off-By: Németh Márton <nm127@freemail.hu>.

CRON fix

Prevent false negatives in cron_pos_tests caused by returning exit value of wrong command. This patch fixes erroneous failure caused by returning return value of a wrong command in cron tests. Signed-Off-By: "Jiri Palecek " <jirka@debian.POK.IBM.COM>.

SCHED fixes

This patch fixes the following error when running sched_cli_serv test case via runltp by making the path of the data file as a runtime option and giving an absolute path of it. Signed-Off-By: CAI Qian <caiqian@cclom.cn>.

UNZIP fix

Fix broken symlink to tst_unzip_file.zip: Creating a link to tst_unzip_file.zip by testcases/commands/unzip/Makefile, has a problem and it seems to be fixed by http://ltp.cvs.sourceforge.net/viewvc/ltp/ltp/testcases/commands/unzip/Makefile?r1=1.2&r2=1.3. So I made a fix (this patch against ltp-full-20081231). Signed-off-by: Seiichi Ikarashi <s.ikarashi@jp.fujitsu.com>.

MSGCTL11 fix

Fix for msgctl11.c: Resending the fix after modifications based on suggestions from Mike Frysinger. PS: I've retained SHRT_MAX return value in the patch below as per the reason stated earlier. Signed-off by: Vinay Sridhar <vinay@linux.vnet.ibm.com>.

LTPSTRESS.sh fix

I encountered a failure on running ltpstress.sh. This problem seems to be introduced by http://ltp.cvs.sourceforge.net/viewvc/ltp/ltp/testscripts/ltpstress.sh?r1=1.26&r2=1.27, Since I don't know why it wanted to eliminate rpcinfo command, I wrote two solutions attached. Signed-off-by: Seiichi Ikarashi <s.ikarashi@jp.fujitsu.com>.

AUTOCONF for EVENTFD tests

Adding AUTOCONF rules for eventfd syscall tests. Signed-off-by: Masatake YAMATO <yamato@redhat.com>.

BLOCK Device Drivers Tests Updates

Add "tc" paramter for "block" testsuite which enables the testsuite to run test cases separately. The default value of tc is 0 which preserves the original behaviour and runs all the available test cases. A user space shell script "run.sh" is also added which helps to run the test cases in kernel space. Signed-off-by: Márton Németh <nm127@freemail.hu>.

FCNTL27 & 28 Fixes

This patch fixes fcntl27 and fcntl28 test cases failures seen on RHEL 4 kernel (2.6.9 based). Because it is kernel 2.6.9, the "expected_result" will be 0. However, the actual return code is the same as other kernels like 2.6.18, as it only allow F_RDLCK option to be placed on a read-only file descriptor (man fcntl). I have no idea where is the above kernel version and expected code mapping originally came from. I have searched the manpage of fcntl(), but not found any mention of 2.6.10. Since there is a check already, #ifdef F_SETLEASE. I have removed the above code like other fcntl* test cases, but I am willing to listen other options. Signed-off-by: CAI Qian <caiqian@cclom.cn>.

IOCTL02 Fix

Patch to Remove Checking for "termio.c_cflag": The only way Test can handle this to make it pass is to avoid checking for this flag which is causing the trouble, which this patch does. Signed-Off-By: Subrata Modak<subrata@linux.vnet.ibm.com>.

AUTOTOOLS Intro

Integrate autotools a bit more so that we can take advantage of the configure features like tool chain selection and build flags. Mike Frysinger <vapier@users.sourceforge.net>

DOCUMENTATION For Makefile Variables

Update to OpenHPI 2.13.2. See http://openhpi.org/ for more details.

AT_ALLOW01 & AT_DENY01 Fixes

The at tests copy the testscript to the home directories of newly created users. This may fail if the home directory does not exist. This patch fixes that by adding an option to create home directories to useradd. Signed-Off-By: Jiri Palecek <jpalecek@web.de>.

PAN Segmentation Fault Fix

This patch fixes a segfault of pan, when the command file doesn't end with a newline. Signed-Off-By: Jiri Palecek <jpalecek@web.de>.

PIDNS Fixes for Build Failures on IA64

Seiichi Ikarashi reported:: I report ia64-specific build failures and a patch for them. Since ia64 glibc does not have the clone() function call, building testcases/kernel/containers/pidns/pidns12.c fails as follows. It's same for pidns13.c, pidns14.c, pidns16.c, pidns20.c, pidns21.c, pidns30.c, and pidns31.c. They should call clone2() instead of clone(), like check_pidns_enabled.c. I attached a patch to fix them. Signed-Off-By: Seiichi Ikarashi <s.ikarashi@jp.fujitsu.com>. Complete mail thread: http://marc.info/?l=ltp-list&m=123232695003986&w=2.

FTEST02 Fix

ftest02: size of 'name' buffer must be more than 3:: name will be passed to mkname function, which will copy to it temporary directory name. So let's it will be 128 as other buffers, passed to mkname. Signed-Off-By: Dmitry Guryanov <dguryanov@parallels.com>.

AUTOTOOLS Updates

Help text needs updating then ... now we need to run make autotools. this will invoke aclocal and automake. we dont actually use automake-generated Makefiles, but the fun helper files (install.sh, config.guess, etc...) come from automake. Here is a quickfix. However, it is not perfect. Could you improve this? Signed-off-by: Masatake YAMATO <yamato@redhat.com>.

AUTOTOOLS Updates

Removed check_header from Makefile of io_* testcases and use autoconf instead of the macro. Signed-off-by: Masatake YAMATO <yamato@redhat.com>.

SYSLOG Updates

This patch fixes the syslog tests on Debian. The tests currently fail on Debian, because they check for a nonexistent file. Besides that, this patch adds rsyslogd as another possibility to supported syslog daemons. The patch changes the detection of syslog_cmd and CONFIG_FILE names; they are all detected by checking for possible files. I have not tested it on a different distro than Debian, but it should work on them too. Signed-Off-By: Jiri Palecek <jpalecek@web.de>.

LCOV Fix

lcov: remove CRLF line breaks in source code when generating html output - added patch by michael.knigge@set-software.de.

AUTOMAKE 1.10 Updates

Create a dummy config.mk when running just make. Require automake-1.10. Mike Frysinger <vapier@users.sourceforge.net>.

BUILD/INSTALL Updates

Info regarding various dependant packages for LTP build/install. Subrata Modak<subrata@linux.vnet.ibm.com>.

LCOV Fix

lcov: modify end-of-line CR removal - s///g is 10% slower than s/// - \r may be 0x10 or 0x13 (see man perlport), Peter Oberparleiter <oberpapr@users.sourceforge.net>.

LCOV Fix

geninfo: need to add CR removal to geninfo as well or checksumming will fail. Peter Oberparleiter <oberpapr@users.sourceforge.net>.

SYSLOG Fixes

[PATCH 1/6] Do not cleanup if it doesn't make sense: This is the first from the series of minor patches to syslog tests. Parts inspired by CAI Qian's remarks. Resend due to line-wrapping problems. - Check for existence of the backup file before moving it back, - Do not restart syslog daemon, if syslog command was not found, Signed-off-by: Jiri Palecek <jpalecek@web.de>.

SYSLOG Fixes

[PATCH 2/6] Use TFAIL/TPASS in some syslog tests. Signed-off-by: Jiri Palecek <jpalecek@web.de>.

SYSLOG Fixes

[PATCH 3/6] Fix paths for detecting syslog daemons: Allow /usr/sbin/syslog-ng as path to syslog-ng, because this is the path used in Debian syslog-ng packages. Also, detect /sbin/rsyslogd as rsyslog, which is its location on Fedora. Signed-off-by: Jiri Palecek <jpalecek@web.de>.

SYSLOG Fixes

[PATCH 4/6] Don't check for existence of the log file before the test with syslog-ng, because it might not exist and still work correctly. Signed-off-by: Jiri Palecek <jpalecek@web.de>.

SYSLOG Fixes

[PATCH 5/6] Add support for rsyslog in not-syslog-compatible mode: This adds the configuration directive: $ModLoad imuxsock.so; to the beginning of the syslog configuration file when using rsyslog. Signed-off-by: Jiri Palecek <jpalecek@web.de>.

SYSLOG Fixes

[PATCH 6/6] Change the message and return value used to report missing supported syslog daemon. - note rsyslog in the message, - use TCONF to report unsuitable configuration, - return 0, which corresponds to other tests failing on TCONF, Signed-off-by: Jiri Palecek <jpalecek@web.de>.

SYSLOG Fixes

CAI Qian wrote: After apply the whole series of patches with the help of '-l'. The only failure for rsyslogd is syslog06: syslog06 0 INFO : syslog: Testing the log option: LOG_NDELAY... syslogtst 1 FAIL : open() has returned unexpected fd: -1, I have noticed this line here, # cat syslogtst.c. so it is not a surprise that open() returned -1. Jiri Palecek <jpalecek@web.de> wrote back: Yes, that code is a gem :-) Does it work with the attached patch?. CAI Qian tested back: It works apart from something untidy.

SYSLOG Fixes

Fix the following build warning: Signed-Off-By: Subrata Modak <subrata@linux.vnet.ibm.com>.

Parrellel build failures in /network/lib6/Makefile

Matt Helsley reported: The dependency description in testcases/network/lib6/Makefile breaks parallel builds: This patch fixes the problem by properly expressing the build depdency between the TARGET objects and runcc.a. Signed-off-by: Matt Helsley <matthltc@us.ibm.com>. Garrett Cooper <yanegomi@gmail.com> replied: Sorry to knitpick, but runcc.a should really be librunc"c.a; otherwise it's not really linkable with ld when using -lruncc. You could also omit the lime with CC if implicit rules are enabled. Other than that the patch looks groovy!. Matt Helsley replied back: Since the -l flag is not being used to link with runcc.a that's not a problem. -l adds the naming requirement and searches multiple directories. Otherwise gcc behaves as if it were just another .o. I think the only reason to prefer -l is if we're going to install it as a library. I checked and, as best I could tell, runcc.a is only used in the network/lib6 testcases. This means using -l has no advantages so I don't intend to change this part of the patch. In fact I can't see why they bothered making an archive at all. But that's a different change than I intend to make :). I guess I never relied much on the implicit rules -- I suppose the implicit rule compiling and linking each target will be triggered because the "empty" rule: $(TARGETS): %: %.c runcc.a did not actually wind up creating its supposed target.. Thanks for the review. I'll post an updated patch soon. This patch fixes the problem by properly expressing the build depdency between the TARGET objects and runcc.a. Rely on the implicit rules as suggested by Garrett Cooper. Signed-off-by: Matt Helsley <matthltc@us.ibm.com>.

Named PIPE Fixes for NOMMU

[Patch 1/2] Used named PIPE in test cases for NOMMU arch instead of anonymous: In NOMMU arch, anonymous PIPE can't be accessed in child process if it is started by vfork/execve. This patch use named PIPE instead. The API sync_pipe_create() and sync_pipe_close() are changed to accept PIPE name. Signed-off-by: Sonic Zhang <sonic.adi@gmail.com>.

Named PIPE Fixes for NOMMU

[Patch 2/2] Used named PIPE in test cases for NOMMU arch instead of anonymous: In NOMMU arch, anonymous PIPE can't be accessed in child process if it is started by vfork/execve. This patch uses named PIPE instead and changes related test cases accordingly. Signed-off-by: Sonic Zhang <sonic.adi@gmail.com>.

IPC Namespace test Addition

Submitting a new testcase on semaphore to test the IPCNS in the containers. This patch contains the batch file to run the test on LTP.

Corrected the indentation. Acked-by: Serge Hallyn <serue@us.ibm.com>. Signed-Off-By: Veerendra <veeren@linux.vnet.ibm.com>.

linux-2.6.28-gcov.patch Fixes

gcov-kernel: fixed problem when compiling without O= parameter - coverage measurement was not available when kernel was compiled without O= parameter - files where not found by gcov - solution: change kbuild to always use absolute paths Peter Oberparleiter <oberpapr@users.sourceforge.net>.

HUGETLB Tests Fixes

Here it goes. What i have tried to do is fix only the broken issues, where the test case(s) will not execute if enough hugepages are not available in the system. Now, i leave it on the discrition of the user to increase the hugepages in their system before executing these tests. Else, if you all agree on some way to autoset that before test execution, it would be welcome. Signed-Off-By: Subrata Modak <subrata@linux.vnet.ibm.com>.

DIOTEST07 Addition

Modify Makefile to include dma_thread_diotest7. Add dma_thread_diotest7. Add test dma_thread_diotest7.sh. Add test dma_thread_diotest7 command file. Add test_dma_thread_diotest7 to runalltests.sh. Signed-Off-By: Subrata Modak<subrata@linux.vnet.ibm.com>.

IPC Namespace test Addition

Test Assertion: - This testcase verifies the semaphore isoloation in 2 diff containers. - It tries to create/access a semaphore created with the same KEY. changelog: version 2 * Modified testcase, to use only 2 pipe's to sync between 2 containers. * Corrected the indentation. Signed-off-by: Veerendra C <vechandr@in.ibm.com>.

IPC Namespace test Addition

Testing shmem isolation between 2 containers: Please find the testcase to test the shared memory isolation in between 2 containers.

Compilation Warning Fixes

This patch fixes compilation warnings introduced recently. Signed-off-by: CAI Qian <caiqian@cclom.cn>.

PACCEPT tests Removal

Paccept() has not been accepted upstream, and accept4() has already been tested in LTP, which does the pretty much same thing as the test here, http://lkml.org/lkml/2008/10/26/123. Hence, remove this test. Signed-off-by: CAI Qian <caiqian@cclom.cn>.

LIBAIO Build Error Fixes

Make ltp compilable without libaio: This is a patch inspired by numerous whining recently seen on ltp-list concerning compile failures when libaio is not present. This includes changes: - add stubs to the aio tests, - remove -laio from doio and pipeio makefile, as it was superfluous, Changed the signatures of main() function (requested by Garrett Cooper).

MMAPSTRESS03 fix for x86_64

sbrk has arguments of type intptr_t, which is long in on x86_64. There is following line in mmapstress03: if (sbrk(-NUM_SEGS * pagesize) == NEG1) { Here the type of argument is int, because of constant NUM_SEGS, and this test fails here on x86_64. So let constants will be long. Signed-Off-By: Dmitry Guryanov <dguryanov@parallels.com>.

EXECVE05 fix

This test case requires write permission for the dummy program. It would fail for those who put LTP on an read-only environment. So this patch copies the dummy test program to and performs the test in a private directory. p.s. this patch copy the one Renaud Lottiaux sent for execve02.c.

GTOD_LATENCY fix

The following patch fixes two problems in loop variables of gtod_latency test case : 1) The loop variable 'k' could overflow on 32 bit systems, leading to a SEGV. 2) The inner loop was not of constant duration. This meant the frequency of calls to usleep() depend on the number of total iterations. It is desirable to make this frequency a constant.

TLIBIO & PIPEIO enhancements

These patches enable AIO and listio in tlibio.c for linux, mostly by reusing code that is already in tlibio.c, and makes non-blocking read()/write() actually work. Also, they change pipeio.c to use this. Comments: 1) Patch 0001 enables aio and other types of io in tlibio.c code. Note that this means programs using functions from tlibio need linking with libaio and librt, 2) Patch 0002 changes non-blocking io in tlibio, so that it doesn't report EAGAIN to the client, but rather waits with select() for the io to become available (it would be possible extend this by adding more wait types). Also, it makes some minor changes to pipeio to make it work (eg. make opening the pipe always block, regardless of non-blocking setting). 3) Patch 0003 adds a semaphore to pipeio, to ensure all children have opened their pipes before reading & writing takes place. This avoids situations where one child gets to open the pipe after the parent deleted it (eg. because of an error). Also, it should eliminate all empty reads. 4) Patch 0004 changes error handling in pipeio to interpret every negative number as -errno. 5) Patch 0005 changes the way the end of the test is handled - before, the test ended after the last child was dead, but possibly before all data was read. The new way is to read all data and only if no data can be read, see if the children are dead. The patches should be applied in sequence. Signed-Off-By: Jiří Paleček <jpalecek@web.de>,

AIODIO Signal Traps enhancements

The aiodio_sparse (and dio_sparse) tests use mmaped region of memory backed by a file, and populate the pages by writing to them. This can fail, eg. when Linux overcommits memory and the newly created pages do not fit; it results in the file not being properly deleted. This patch fixes that by trapping signals in these test (I used the standard libltp functions for that) and deleting the file in a cleanup function. Sorry that the patch may be little unclean - it was hand-edited. I will do something about that if it matters. Signed-Off-By: Jiří Paleček <jpalecek@web.de>.

UTIMNENSAT01 Fix

Veerendra <veeren@linux.vnet.ibm.com> reported: In the latest LTP release ( LTP-full-20081130) the make is failing for Power machines for the 'utimensat' tests. Jiri Palecek <jpalecek@web.de> replied: This is because TCID is needed to call tst_brk if the syscall doesn't exist or optimization doesn't eliminate the call. At the first sight, it might seem that syscall() is not called when NR_utimensat is undefined, because it is guarded by #ifdef, but it's not really so, because NR_utimensat is stubbed in linux_syscall_numbers.h. To fix it, apply the first patch, which moves the definition of TCID outside the #ifdef block - it should be there anyway. The second patch removes the conditional compilation altogether, because it is never effective. The patches should be applied in sequence. Signed-Off-By: Jiri Palecek <jpalecek@web.de>.

MEM01 Fix

Mem01 test case sometimes trigger OOM Killer. As the result, the test failed with a non-error code. This patch reduces the chance of OOM Killer by always reserving 16MB memory. It is a trade-off between not testing all available memory and dealing with false failure (extra work to waive the failure in automated environment and clean up unexpected test leftovers). I prefer the formal. Signed-off-by: CAI Qian <caiqian@cclom.cn>.

UNZIP Fix

commands/unzip: check exit code of all comands: 1. don't redirect all output to /dev/null.

Signed-Off-By: Andrew Vagin <avagin@parallels.com>.

OPEN POSIX mq_send fix

Version 2: The test failed a few hours after I sent this off. I think it was caused by a pid collision which caused the test to use the same queue as an earlier failed test that didn't close out its queue. This version of the test uses O_EXCL to avoid this. And it cleans up the queue on every failure case. This test was racy. It relied on signals interrupting sleeps to do syncronization between processes. It also didn't cleanup the queue on the failure cases and assumed that its queue didn't already exist. This patch fixes these issues. Reported failures: https://bugzilla.novell.com/show_bug.cgi?id=375897. Instead use a syncronization pipe to have the child thread send messages to the parent thread (with reasonable timeouts since this is testing blocking calls). # Apply to root of ltp-full-20081031 tree $ cd testcases/open_posix_testsuite/ $ make conformance/interfaces/mq_send/5-1.test $ conformance/interfaces/mq_send/5-1.test Signed-off-by: Brandon Philips <bphilips@suse.de>

PIDNS Tests Addition

This is a proposal for 2 new testcases in the pidns testcases. They are related to POSIX message queues and notification on message arrival. Could you please review them? If a process registers for asynchronous notification on a POSIX message queue, it gets a signal and a siginfo_t structure when a message arrives on the message queue. The si_pid in the siginfo_t structure is set to the PID of the process that sent the message. If the process that sent the message is not in the same namespace as the notified one, this should be taken into account. pidns30 : notified process is in a descendant namespace wrt to the notifier. so the signal receiver doesn't know about the sender's pid. pidns31 : notified process is in an ancestor namespace wrt to the notifier. so the signal receiver should get the sender's PID in the signal receiver namespace. They currently fail, since the si_pid is not correctly set. But I just proposed a patch to fix this (see http://lkml.org/lkml/2008/12/5/13). This testcase checks if the si_pid is correctly set when a process that has registered for notification on a posix mqueue is in a descendant namespace wrt the process that sends a message to that posix mqueue.

Fix Warnings and Badness

Per request of Mike Frysinger, I resend this patch. The patch itself is the same, but the explanation is extended. Hope it's better this time. Hello, I'm sorry to say this, but some changes in the "Fix Warnings and Badness v2" patch[1] from October actually create bugs in the ltp tests. I think they should be reverted by applying the attached patch. The problems are of those types: 1) Calling: pthread_create(&th, &newattr, (void *)&new_thread, (void *)&newsockfd) is wrong if eg. newsockfd is a variable subsequently modified by the parent thread, not protected by locking. This is because there is a data race between the read in the new thread and the write in the parent thread. Moreover, it is quite often meant to pass different values to more threads in the ltp tests, which results in the different threads actually sharing the variable, which leads to unpredictable results. 2) Calling pthread_exit((void *)&exit_val); is wrong if exit_val is a local or thread-local variable, incl. errno. These variables cease to exist when the thread finishes, so subsequent dereferencing & read in the joining thread would read nonexistent variable. I think they should be reverted, because the warning (conversion pointer/integer) doesn't mean anything bad in this context (provided you use the same type on both sides, eg. the calling thread and the created thread) and other solutions just add unnecessary complexity. The patch goes a little further, while I was searching for related problems, I've found one typo and changed the signatures of some thread functions (they really should be (void* (*)(void*)), not (void* (*)(int))). I've discovered this when I debugged a deadlock in test_1_to_1_threads. BTW, shouldn't the first (or last) thread in this test call t_recv instead of t_send (see the relay function).

Fixes for lstat01A_64 & stat04_64

The problem is noticed only for these 2 tests lstat01A_64 and stat04_64. Analysis of the problem showed that these tests are called from runtest/syscall file. The problem is noticed because the symlink01.c file doesn't have implementation to take care lstat01A_64 and stat04_64 arguments that are passed in the file runtest/syscall. Solution: Simple solution is to remove lines. lstat01A_64 symlink01 -T lstat01_64 stat04_64 symlink01 -T stat04_64 from runtest/syscall. Other option is to provide feature in symlink01.c so that it can execute these tests successfully. I worked on one such patch. Please have a look.

Background: CONFIG_GCOV_HAMMER indicates a modified gcc version which is not the majority of cases: Some Linux distributions ship a modified version of GCC 3.3.x that produces GCOV data incompatible with the format of the standard GCC 3.3.x. If you are using such a distribution, you need to enable this option for the GCOV kernel support to work correctly. Signed-Off-By: Peter Oberparleiter <oberpapr@users.sourceforge.net>.

BASHISM & TYPOS Fixes

Hello, these are some little fixes I've created for ltp. They are typos, fixes for compiler warning, bashisms in the makefiles etc. Signed-off-by: Jiri Palecek <jpalecek@web.de>.

NON-EXISTANT SYSCALLS handling Fixes

when building Debian ltp package on alpha, the package failed to build, because alpha lacks some of the syscalls (the xxx_16 ones). See: http://experimental.debian.net/fetch.php?&pkg=ltp&ver=20081031%2Bdfsg-1&arch=alpha&stamp=225968365&file=log&as=raw. I have created some patches, which fix this behaviour (ie. the build doesn't fail then). They work like this: 1. Syscalls which are potentially missing on some architectures are listed in the stub-list, 2. If a syscall(x) is called and x is 0 (a value of undefined stub syscalls), the test is aborted by tst_brk(). This is accomplished by a macro wrapper over the syscall() function (this almost eliminates the need of changing the tests in question, and allows the compiler to eliminate parts of tests of nonexistent syscalls as dead code). The attached patches implement this. Some remarks: - the syscalls added to the stub list are the ones which appear in the kernel sources as IGNORE_name-of-syscall, - the macro is for gcc only. The test using this mechanism (ie. #including linux_syscall_numbers.h and calling syscall()) must define static function void cleanup(void) to be called when the syscall is missing (the patch also handles this for tests that lack it). Signed-off-by: Jiri Palecek <jpalecek@web.de>.

EXECVE04 Fixes

Fix success detection in execve04 test: The execve04 test works like this: It sets up the environment, calls execve() and expects failure. However, this has two bad consequences if the call actually succeeds: 1. The failure (ie. success of the call) is unnoticed, 2. The test leaves loads of files in the temporary directory. all of them being caused by the fact that the test no longer runs after a succesful exec(). This patch fixes the situation by calling exec in a child only. The failure (or success) is gathered from the child's exit value. Signed-off-by: Jiri Palecek <jpalecek@web.de>. This patch fixes the error, that code exhausting the file descriptor table in execve04 test actually doesn't exhaust the fd table at all. Signed-off-by: Jiri Palecek <jpalecek@web.de>.

CHOWN Fixes

Don't break chown tests on non-catastrophic failures. Signed-off-by: Jiri Palecek <jpalecek@web.de>.

tst_brkm Fixes

Do not call tst_brkm from the cleanup function in some tests: It is bad for the cleanup function to abort by calling tst_brkm, because in that case, further cleanup will not be performed. This patch fixes it in some chmod*, chown*, fchmod* and fchown* tests by substituting tst_resm for tst_brkm. Signed-off-by: Jiri Palecek <jpalecek@web.de>.

FALLOCATE Fixes

Call cleanup() at the right places to prevent fallocate tests leaving files in the temporary directory. Signed-off-by: Jiri Palecek <jpalecek@web.de>.

AUTOCONF introduced for SIGNALFD test

SCTP Fix

Use the SO_REUSEADDR option in sctp tests to prevent bind error shortly after another test ended: I've noticed a bunch of errors in the SCTP tests, all of them being for the same reason, "bind: address already in use". I tried using the SO_REUSEADDR option on the socket, as if it was TCP, and it helped. However, I know almost nothing about SCTP, and don't know whether the same situation (applications binding to the same port quickly one after another) has the same problems and solution, or if it is just a kernel bug/misconfiguration/whatever else.

hugemmap02 Segmentation fix

Adam Litke <agl@us.ibm.com> Replied: Unfortunately, when you mmap using the MAP_FIXED flag, you can overwrite an existing mmap in the address space. Please do the following to check if this has happened: 1. Insert a 'getchar();' call above line 155 in the test source code above and recompile the test. 2. Run the test. When it pauses (waiting for input at the getchar() call), hit <ctrl>-z to background the test. 3. Determine the pid of the test case using ps. 4. Collect the /proc/<pid>/maps for the appropriate pid. 5. Paste that output here in this bug. My suspicion is confirmed. This is a LTP test case bug. All of the above mappings will have been overwritten by the mmap call on the hugetlbfs file at address 0. This will most certainly cause your program to crash and burn. To fix the test case, I would recommend removing the MAP_FIXED flag from that mmap call and checking the address you get from mmap. If it's zero, you'll know a mapping could be created at the bottom of the address space. If it's -1, the mmaping failed. But if it's >0, you'll have to decide how to handle the case where the mapping could not be placed in the spot you requested. This case would not be a failure, just a failure to test the scenario you wanted to test. I assume the LTP test harness has a way to represent an insignificant test result. You might just treat this case in the same way you handle mmap() == 0. Signed-Off-By: Cijurajan Kollanoor <cijurajan@in.ibm.com>,

CREAT07 fix for running in a private directory

This test case requires write permission for the dummy program. It would fail for those who put LTP on an read-only environment.

ACCEPT4() syscall test addition

Initial Porting of accept4() syscall test to LTP by Subrata Modak <subrata@linux.vnet.ibm.com>. Originally written by Michael Kerrisk <mtk.manpages@gmail.com>. Later modified to suite compilation on different systems by Jiri Palecek <jpalecek@web.de>, who wrote the following:I have some nitpicks, in decreasing severity: First, the syscall, I believe, is not targeted at i386 and x86-64 only. Therefore, it is not wise to have these explicitly mentioned in the code. Also, it would be better not to "#error" if the arch isn't one of those fortunate, because ltp should build on others too. This should be fixed by patch 1. Disclaimer: This patch should make it compile (and fail at runtime with TCONF) on all kernels that don't have the syscall, and actually run the test on all kernels that do, depending on kernel headers version. However, I didn't test this (especially the selection of the syscall), so it needs to be checked. Second, if any of the syscalls vital for the test fails, it's preferable to output the error message too, and call tst_brk() for cleanup (patch 2). Third, there it would probably be better to use TFAIL/TPASS for recording success and failure instead of manual boolean flags (patch 3). Last, I think a successful test should print as little as possible and multiline messages like "calling syscall..." are really not that useful. Patch 4 disables them.

RT Tests update

The test case gtod_latency in realtime causes soft lockups on some machines. This is because the test hogs the cpus for a long time, because it's main loop runs at SCHED_FIFO, 99. We have seen soft lockups mainly on LS20 machines (x86_64, Opterons). The following patch introduces a sleep after some iterations of the test. This ensures that the test doesn't hog the cpu completely and hence avoids soft lockups. Testing done: Compiled with the patch and observed that the soft lockups are gone. Also observed that the latencies are not affected. In fact latencies improve with this patch on most hardware. Changelog: * Introduce periodic sleeps in the busy loop of gtod_latency to avoid soft lockups. Signed-off-by: Sripathi Kodi <sripathik@in.ibm.com>. Acked-by: John Stultz <johnstul@us.ibm.com>.

NETNS fixes

The below patch would replace the 'source with .' for containers in netns.Signed-Off-By: Veerendra <veeren@linux.vnet.ibm.com>.

I386.in fix

The file testcases/kernel/include/stub-list was recently removed. It contained the list of syscall numbers which, if not present in the kernel headers or in one of the architecture-specific lists, should be defined as 0 (a stub value). Now, this list is automatically generated as union of the architecture-specific lists. However, some syscalls only appeared in stub-list, which means they are not stubbed now, so architectures lacking them will probably fail to build (alpha...). To overcome this, I have added these syscalls to the i386 list, which means they will be defined whenever they are defined in the kernel sources, on i386, and stubbed otherwise. See the attached patch. BTW, the list of syscalls is not exhaustive. In the attachment filtered-syscalls, there is a list of syscalls which appear as IGNORE_syscall-nr in the kernel sources (which means they are missing on some architecture), but are not used in ltp or their use is guarded by an #ifdef. They would have to be added too, if some test explicitely mentions them (eg. getresgid16). Signed-off-by: Jiri Palecek <jpalecek@web.de>.

RT Tests Fixes

Fix busy loop in realtime: The routine busy_work_us(), which is the busy work loop function in realtime test suite is supposed run for as many microseconds as requested for. However, I have observed that it runs too fast on some hardware. I looked at the code and saw that we are statically setting the loop counters, which means the duration of the busy loop varies with the cpu speed. Further, the busy loop is affected by compiler optimizations. On some hardware it provides only 50% of requested delay, whereas with -O3, it finishes even faster. What we need is a method to dynamically tune the delay loop based on the machine where the test is being run. It should not be affected by compiler optimizations as well. The following patch does that. It applies on the latest cvs. Signed-off-by: Sripathi Kodi <sripathik@in.ibm.com>, Acked-by: Chirag <chirag at linux.vnet.ibm.com>.

The issue(s) like linking to proper libraries while building and finding those libraries to run should be properly resolved. If they require specific libraries to to build/run, that should be properly documented. Users should be able to find those libraries and install them (if it does not come with the system in first place), so that they can start using those tests. If people can start using those tests, then there will be more people who can help fix issues related to tests themselves. It would be nice if you can send a patch (against latest CVS) which would re-enable the TI-RPC tests to build/install/run in LTP properly. We can see the test fails later.

Release of 2.6.27 GCOV kernel to LTP community

PIDNAMESPACE fix

If we unshare pidns without unsharing mounts namespace, and then do a mount -t proc none /proc, then the new proc sits over the original proc for the whole system. Since pidns03 wasn't using CLONE_NEWNS, when it exited /proc showed zero tasks. This can be fixed by doing 'umount -l /proc', but 'umount /proc' is insufficient. More to the point, pidns03 wasn't trying to clean up /proc at all. So make it use CLONE_NEWNS so its private procfs will be automatically cleaned up. Signed-off-by: Serge E. Hallyn <serue@us.ibm.com>.

PTRACE06 fix

The new ltp-full-20080930.tgz seems to include some new ptrace tests (ptrace04 and ptrace06) that do a #include for spawn_ptrace_child.c. Now I find that if I do a "make clean" it removes this spawn_ptrace_child.c ... is this expected and desired? Also is there supposed to be a way to generate the spawn_ptrace_child.c and any other files removed after "make clean" ? Thanks, - Mark Ver. Yes, I believe it's an error. The spawn_ptrace_child.c file is necessary to ptrace04 and ptrace06. To do a #include *.c file is not a good coding style. The simplest solution is to rename the spawn_ptrace_child.c to spawn_ptrace_child.h. Also you can add inline as the prefix of functions, then the spawn_ptrace_child.h file looks more like a header file. Thanks, - Jin Bing Guo.

SHMEM_TEST_06 fix

With Exec-Shield in place, the Kernel automatically adjusts the stack downward by a random amount of bytes. This will cause the test failed occasionally on IA-32, because the 11th requested chunk of address space (bfe00000-bff00000) has already been used by the stack. For example, stack could be at bfe0b000-bfe20000, and then, shmat(2) failed, mykey to uniquely identify the shared memory segment 0x451005ae. Get shared memory segment (1048576 bytes). Attach shared memory segment to process: ERROR [line: 205] shmat failed - return: 0xffffffff: Invalid argument. It looks like the stack adjustment has a range that it could be chosen, so I changed the start of 11th address space to a lower address. Tests showed that the stack will not go downward that much. In addition, there are a few minor fixes, - keep the width of comments within 72 characters. - remove unnecessary 0x prefix. Signed-off-by: CAI Qian <caiqian@cclom.cn>.

If anybody happens to know the exactly version it has started to be implemented, I'll be happy to re-send the revised patch. Signed-off-by: CAI Qian <caiqian@cclom.cn>.

TIMERFD support for ARM architecture

I'm using an embedded arm processor (Xscale) and I get the following compile error: timerfd01.c:90: error: 'NR_timerfd_settime' undeclared (first use in this function). I have dug through past patches for this exact problem and have seen it come up with other processors and I have put together a patch that *should* address the issue. I tested it on my system and everything seems to work. I based the macro info off of: http://kerneltrap.org/mailarchive/git-commits-head/2008/4/22/1543584/thread. Here is the patch. Signed-Off-By: Shane Volpe <shanevolpe@gmail.com>.

Better Debug support for SHMEM_TEST_06

This patch adds some debug messages when shmat(2) failed, so we could tell if the failure was because the requested address space has been used. In addition, it fixes the output of failed error code to a more meaningful form. This patch should be applied on the top of another patch I sent earlier with title "shmem_test_06 Failed with Stack Randomization". Tested successfully on a x86_64 machine. Signed-off-by: CAI Qian <caiqian@cclom.cn>.

INOTIFY fixes

When I tested the inotify02 on ppc64, it passed all tests and returned 1 with an unnecessary event. After looking into the code, there were 9 tests in sum in inotify02. So I think the unnecessary event should not be regarded as a failure when the 9 tests all passed. Same problem was in inotify01. The patches fixed them.

CONNECTOR fixes

This patch fixes build failures seen on RHEL 4 (2.6.9 based Kernel), and several warnings. The build failures are caused by pec_listener.c and then ptrace06.c, It because the Kernel version checking code is incorrect from it, as you can see from the error message above, "/bin/sh: ../../bin/tst_kvercmp: No such file or directory". I solve it by querying an entry in proc file system instead. For ptrace06.c case, PTRACE_GETSIGINFO and PTRACE_SETSIGINFO are unavailable in this version of Kernel, Given that this test also fails to compile for IA-64 entirely (please see more details on one of my previous emails sent not long ago), I disable this test temperately until those problems have been fixed. In addition, it fixed the following unnecessary compiling warnings. Finally, check_for_unshare.c:21: warning: implicit declaration of function `tst_kvercmp'. Signed-off-by: CAI Qian <caiqian@cclom.cn>.

GETHOSTID01 fix

The gethostid01 test fails when the host id is not set on a system. The gethostid() call retrieves "00000000" as the host id. Added a check to compare the return value with "000000" (omitted 1st two 0's as they could also be 0x on some systems; needs confirmation). Signed-off by : Vinay Sridhar <vinay@linux.vnet.ibm.com>.

BASH fixes

Hello. I had two errors when compiling the CVS version with Ubuntu. The one in regen.sh might have to do with some dash limitation (it complains about not supporting more than 32 shifts.) The one with the Makefile has to do with the version of lex I have here (lex 2.5.33) complaining about -l not accepting an extra argument (I believe it interprets the w as such).

INODE01 fix

Avoid buffer overflow when PID exceeds to 4-digit limit. char array root has to contain at least 'A' + pid + '\0', which only works pid of testprcess is a 4-digit PID.

LTP-AIODIO.PART3 fix

Now that fsx-linux is the same for fs, nfs and ios (I'm working with ltp-full-20080831.tgz) we have to adapt the runtest/ltp-aiodio.part3 file: (-A and -Z options are no more supported by fsx-linux). Signed-Off-By: Jacky Malcles <Jacky.Malcles@bull.net>.

PREFIX & DESTDIR fixes

CFLAGS fixes

Avoid overwriting of compiler specific flags in open posix testsuite. Instead of overwriting CFLAGS, append custom flags. Don't append debugging info, optimizing or warning related compiler flags. This would "overwrite" the user definied CFLAGS again. Signed-off-by: Daniel Gollub <dgollub@suse.de>.

LOGFILES Corruption fixes

Logfiles of the ltp testdriver "runltp" can get corrupted due to "unsafe" temporary directories and not failing when temporary already exist. The temp directory is /tmp/ltp-$$ which can cause logfile corruption once the PID overflows, since "mkdir -p" will NOT fail, and runltp starts writing into an already existing log directory. This patch creates a temporary directory by using "mktemp", which replaces the "mkdir -p" call. runltp will fail once "mktemp" runs out of combinations (instead of corrupting logfiles silently). Patch is based on the idea from Erik Hamera to create more "safe" temp directories. Various patch improvements/fixes got contributed by Klaus Wagner as well.

Any idea on if it is a test code issue or OS bug? Daniel Gollub <dgollub@suse.de> replied that I just sent some patches for setgroups02_16 - looks like it's a similar problem for setgroups01_16 (for some reason setgroups01_16 didn't failed for me, only setgroups02_16).

ADE fix

The file_test detects MSB architectures by grepping for "power" or "ppc" in /proc/cpuinfo. This is unfortunate if, on a LSB architecture, /proc/cpuinfo contains the word "power_management".

Re-introduce locals. The issue I was solving when making this patch was checkbashisms (http://packages.debian.org/sid/devscripts) complaining about it, so I had to patch it to get rid of lintian warnings. I've checked that: - the variables are always initialised before use in the testXX functions, - the testXX functions don't recurse nor call each other, - the variables are not used outside testXX functions, so IIUC, the transformation should be safe. However, if you're seriously worried about it, you can reintroduce the locals by applying the attached patch, it wouldn't matter to me. Signed-Off-By: Jiri Palecek <jpalecek@web.de>. Mike Frysinger <vapier@gentoo.org> wanted them back.

It is still possible that one of those addresses has been used due to address space randomization or whatever reason. This is because the chosen address starting from 80000000 has already been used. This patch fixes the problem by letting system choose suitable addresses at which to attach the segments, and still satisfy the purpose of the test - simultaneous attachment of more than ten shared memory regions to a process.

At_allow01 and at_deny01 test cases always fail, because the result code handing is incorrect. This patch fixes it, and also tidy up code a little bit. In addition, looks like there is a bug for at utility with a non-login shell, so I suppose it does not hurt to work around this particular bug by using a login shell. Tested successfully on a x86-64 and s390x machines. Signed-off-by: CAI Qian <caiqian@cclom.cn>.

FSX-LINUX duplication cleanup

This patch drops the redudant copies (in total three copies of fsx-linux.c from:- testcases/kernel/io/ltp-aiodio/- testcases/network/nfs/fsx-linux. The only copy of fsx-linux.c will stay in: - testcases/kernel/fs/fsx-linux/fsx-linux.c. Attached patch adapt the TCbin= variable of the runtests file to the install target "$LTPROOT/testcases/bin" to find the (shared) build of fsx-linux. Signed-off-by: Daniel Gollub <dgollub@suse.de>. Acked-by: CAI Qian <caiqian@cclom.cn>.

CRON_TESTS.sh fixes

The following patch complements previous ones to fix/improve the behaviour of cron_tests.sh script. Some fixes inspired in CAI Qian's previous posts. Changes: 1- Added LANG= in the script executed by cron to avoid issues with internationalization. 2- Reordered some tests so that one checks if one of the variables TS_MIN is empty (in case there was some problem to create the file tst1_cron.out). 3- Eliminated the \t\n from the output strings that caused the problem reported by Subrata. 4- Fixed the order the expected x received values are printed out to the output log. This version fixes an error in the previous patch that prevented it from applying correctly and added minor cosmetic changes. Signed-Off-By: Elder Costa <elder.costa@terra.com.br>.

LTP Changes during SEPTEMBER 2008

Task Title

Task Description

libclone.c fix

Fix build error for libclone.c. Signed-off-by: Veerendra Chandrappa <vechandr@in.ibm.com>.

netpipe Makefile fix

Set executable flag for netpipe.sh without chmod.sh which just performs an santiy check if the user is root to run chmod 755, which doesn't require root priviliges. Signed-off-by: Daniel Gollub <dgollub@suse.de>.

libtestsuite fix

sync_pipe_close() returns an uninitialized value when it is passed an already closed pipe. Signed-off-by: Roy Lee <roylee17@gmail.com>.

GETEGID16 syscall test cases addition

sync_pipe_close() returns an uninitialized value when it is passed an already closed pipe. Signed-off-by: Roy Lee <roylee17@gmail.com>.

SWITCH syscall test cases addition

This can only be tested on a POWER6 machine. A program to test it is attached. --Paul Mackerras. Thanks for sharing the test case with LTP. I have ported it to bare minimum LTP requirement and ran it on various architectures and kernel versions to test out the behaviour of the test on these machines. Yamato, When you find time, kindly add more specific stuff that we have specially for the LTP syscall tests, things like running in a loop, running concurrently, etc. And here goes the Patch. Paul, you can propose more modification to this if you wish to: Signed-off-by: Paul Mackerras <paulus@samba.org>, Signed-off-by: Subrata Modak <subrata@linux.vnet.ibm.com>.

UTIMENSAT01 fix

I have seen that in some of my systems, utimensat fails to build because of some definitions missing in system headers. Do, you think we can apply the following patch: Signed-Off-By: Subrata Modak <subrata@linux.vnet.ibm.com>.

SWITCH01 fix

Looks OK as far as I can see, except that I wonder why you check for being root: since there is no restriction by the kernel on which processes can use this system call. A process can't do anything to any other process using this system call, so there's no reason to restrict it. Also you might like to call it "endian_switch()" rather than just "switch()". Paul Mackerras <paulus@samba.org>.

AWK replacing GAWK fix

The following two scripts cannot execute correctly on my box, which doesn’t equip gawk but awk (busybox). This patch makes them, as well as other scripts( see the patch), to not explicitly using gawk but awk. roylee@andestech.com.

tst_tmpdir() cleanups

This patch does the following: 1. These test cases failed with "open returned unexpected errno 2" because the child process falls through to execute redundant cleanup(), 2. Added code to use the tst_tmpdir()/tst_rmdir() APIs. Signed-Off-By: <roylee@andestech.com>

CONTAINERS cleanup

Remove redundant bits from the container test script. Keep the nicer/self-consistent info. Add proper dependencies on check_for_unshare rather than shoehorning it in as a MAKE command in *only* the 'all' target. Signed-off-by: Matt Helsley <matthltc@us.ibm.com>,Acked-by: Serge Hallyn <serue@us.ibm.com>,

CONTAINERS cleanup

Make these rules a tiny bit more generic using the automatic $@ variable. This means anyone copying this line is less likely to make copy/paste errors. Signed-off-by: Matt Helsley <matthltc@us.ibm.com>, Acked-By: Serge Hallyn <serue@us.ibm.com>.

CONTAINERS cleanup

When it comes to this program, why should we care what the arch is? Shouldn't the SYS_ and NR numbers alone tell us if unshare() is relevant here? Signed-off-by: Matt Helsley <matthltc@us.ibm.com>, Acked-by: Serge Hallyn <serue@us.ibm.com>,

CONTAINERS cleanup

Now that we have proper dependencies on check_for_unshare we take explicit tests for unshare out of the top-level make file and distribute to each subdir Makefile as ifeq...endif sections which control which targets to build. While it doesn't avoid descending into subdirs it's easier to read and check the make code when most of the build rules don't have shell flow control. Even better if we could change the contents of SUBDIRS based on the results of running check_for_unshare. Also note the use of := and not =. info Make is our friend. Signed-off-by: Matt Helsley <matthltc@us.ibm.com>, Acked-by: Serge Hallyn serue@us.ibm.com>,

CONTAINERS cleanup

Now that they are in it's best to drop the noltp junk leftover from the LTP port of the container tests. Signed-off-by: Matt Helsley <matthltc@us.ibm.com>, Acked-by: Serge Hallyn <serue@us.ibm.com>.

CONTAINERS cleanup

Use non-recursive assignment. This means, for example, that: SRCS $(wildcard *.c) will call the wildcard function, substitute the output, and assign it to SRCS. Recursive assignment (plain) would use the output and continue performing substitutions until no further substitutions could be made. Signed-off-by: Matt Helsley <matthltc@us.ibm.com>, Acked-by: Serge Hallyn <serue@us.ibm.com>.

NETWORK script(s) fixes

The operator for string unequivalent check is not '-ne' but '!='. Signed-off-by: Mitsuru Chinen <mitch@linux.vnet.ibm.com>.

NETWORK script(s) fixes

The state of finger service is not got correctly as an option for netstat is lacked. Signed-off-by: Mitsuru Chinen <mitch@linux.vnet.ibm.com>.

Although ping6 doesn't have -R option, it is specified. It should be removed. Signed-off-by: Mitsuru Chinen <mitch@linux.vnet.ibm.com>.

SWITCH01 build error fixes

Fix the build error for some systax error. Also fix some warnings. Signed-off-by: Jin Bing Guo <guojb@cn.ibm.com>.

HACKBENCH OOM-Killer fix

Part of these tests are pretty much enough to invoke an oom-killer. Let the test do the functional testing part, and, we can do stress testing with hackbench seperately. Signed-Off-By: Subrata Modak <subrata@linux.vnet.ibm.com>.

Foo* syscalls test cases Macro Definition file

I worked on 2 test cases for foogid16 system calls; and I will do 5 more. All these test cases have the same macro. So I'd like to introduce compat_gid.h; and put the macro to the file. Could you add compat_gid.h to testcases/kernel/syscalls/utils/ and apply patches for existing test cases? Here after I'd like to use the compat_gid.h in newly ported test cases. Signed-off-by: Masatake YAMATO <yamato@redhat.com>,

Containers Makefile fix

Add $(CFLAGS). From: Roy Lee <roylee17@gmail.com>.

switch01 renamed to endian_switch01

Paul <paulus@samba.org> wanted the name to be endian_switch. Michael Kerrisk <mtk.manpages@googlemail.com> seconded his suggestion.

Enable CONNECTORS run by default

Don't warn that TCID, TST_TOTAL and TST_COUNT is not set when using tst_kvercmp. And. Check /proc/net/connector to see if process event connector is supported or not. Also merged some cleanups done by Matt Helsley. Signed-off-by: Li Zefan <lizf@cn.fujitsu.com>.

semaphore_test_03 Memory Leak Fix

Fix memory leak in semaphore_test_03. Signed-off-by: Jin Bing Guo <guojb@cn.ibm.com>

Compat_16 & newer_64.mk fix

I think TST_NEWER_64_SYSCALL is better than TST_NEWER_64 because newer_64.mk is local to testcases/kernel/syscalls. This rule is applicable to compat_16.mk. Signed-off-by: Roy Lee <roylee17@gmail.com>. Signed-off-by: Masatake YAMATO <yamato@redhat.com>.

SIGNALFD syscall test cases addition

Addition of signalfd() syscall test case(s) to LTP. Signed-Off-By: Masatake YAMATO <yamato@redhat.com>.

RT Tests cleanup

RT Tests cleanup

This patch ensures that the python scripts support utf encoding. Prior to the patch, the python scripts would exit with this error: File "parse-testpi1.py", line 3 SyntaxError: Non-ASCII character '\xc2' in file parse-testpi1.py on line 3, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details This patch fixes it. Tested: Running all the python scripts. Signed-Off-By: Chirag <chirag@linux.vnet.ibm.com>.

GETCPU01 fix

This patch fixes the getcpu patch for parisc (and probably other platforms as well). The check for "GLIBC >= 2 && GLIBC_MINOR >= 6" is wrong. It breaks as soon as a glibc 3.0 would be published. Replace it with GLIBC_PREREQ(2,6). Tested on parisc and i386. Signed-off-by: Helge Deller <deller@gmx.de>.

SIGNALFD01 fix

Garrett, thank you for input. I think my patch works as you wrote. My patch tries sys/signalfd.h then linux/signalfd.h. So I can say my patch tries "whatever's the newest standard"(glibc header file) then "deprecated version"(no glibc header but kernel header file). It is important point. Thank you. CROSS_CFLAGS should be considered when checking the existance of header file. I update the last patch. It does 1. If sys/signalfd.h is not available, use syscall to invoke signalfd. 2. CFLAGS is considered when checking the existance of signalfd.h. 3. Checking the existance of signalfd.h in addition to checking sys/signalfd.h and linux/signalfd.h. Signed-off-by: Masatake YAMATO <yamato@redhat.com>.

CONTAINERS compilation error fix

When I built and installed the latest LTP cases, some errors broke the install process. And the system didn't support "unshare". The patches modified these files.

Result before applying patch: # ./mmapstress01 -h ./mmapstress01: invalid option -- h usage: ./mmapstress01 -p nprocs [-t minutes -f filesize -S sparseoffset -r -o -m -l -d] mmapstress01 1 FAIL : Test failed Result after applying patch: # ./mmapstress01 -h ./mmapstress01: invalid option -- h usage: ./mmapstress01 -p nprocs [-t minutes -f filesize -S sparseoffset -r -o -m -l -d] Signed-off By: Rishikesh K Rajak <risrajak@in.ibm.com>

OPEN_POSIX fix

The Makefile in the mqueues- and semaphores directory of the open_posix_testsuite try incorrectly to overwrite the compiler and have no clue about the fact that there could be a cross compilation scenario, so it tries to search libs in /usr/lib. This results in the following command line: make[2]: Entering directory `<somewhere>/ltp-full-20080831/testcases/open_posix_testsuite/stress/mqueues' gcc -Wall -O2 -g -I -L/usr/lib -lpthread -I../../include multi_send_rev_1.c -o multi_send_rev_1.test -lmqueue which is obviously wrong for cross compilation. With this change the right compiler and the right libs from the toolchain are being used. Signed-off-by: Robert Schwebel <r.schwebel@pengutronix.de>.

OPEN_POSIX fix

The Makefile in the mqueues directory of the open_posix_testsuite wants to link the mq_open testcase against libmqueue. POSIX.1-2001 states: "Link with -lrt". So this is definitely wrong, and we do what the standard recommends. Signed-off-by: Robert Schwebel <r.schwebel@pengutronix.de>.

OPEN_POSIX fix

The semaphores tests of the open_posix_testsuite want to link again libposix1b, but I don't have any idea why it tries to do so. However, it results in: gcc -Wall -O2 -g -I -L/usr/lib -I../../include multi_con_pro.c -o multi_con_pro.test -lposix1b -lpthread /usr/bin/ld: cannot find -lposix1b. This patch removes the bogus library. Signed-off-by: Robert Schwebel <r.schwebel@pengutronix.de>.

NETWORK lib6 fixes

To make POSIX namespace clear, glibc-2.8 requires people to define _GNU_SOURCE when they use Advanced Socket APIs. Signed-off-by: Mitsuru Chinen <mitch@linux.vnet.ibm.com>.

NETWORK lib6 fixes

The definitions, ICMP6_RR_PCOUSE_DECRVLTIME and ICMP6_RR_PCOUSE_DECRPLTIME are wrong. According to RFC3542, they should be CMP6_RR_PCOUSE_FLAGS_DECRVLTIME, ICMP6_RR_PCOUSE_FLAGS_DECRPLTIME. Signed-off-by: Mitsuru Chinen <mitch@linux.vnet.ibm.com>.

NETWORK lib6 fixes

"man 3 cmsg" says "Ancillary data should only be accessed using the CMSG macros and never directly." Indeed, when we handles cmsghdr mamber directly, this test falls into the infinite loop on a x86_64 environment. Signed-off-by: Mitsuru Chinen <mitch@linux.vnet.ibm.com>.

NETWORK lib6 fixes

When we compile the test codes with -Wall option, lots of warning appear. It is better to remove them for the future debbuging. Signed-off-by: Mitsuru Chinen <mitch@linux.vnet.ibm.com>.

GETGID16 syscall test cases addition

ipc_stress fix

In testcases/kernel/ipc/ipc_stress/cleanup file, it uses the command "ipcrm " to delete the ipc resources. But usage is deprecated and noneffective in some cases. Signed-off-by: Jin Bing Guo <guojb@cn.ibm.com>.

float segmentation fix

Segmentation fault error: When I ran runtest/math with runltp, the float cases worked well. But they would drop into segmentation fault when they were called directly in command line. The reason is to input "NULL" to strlen() which caused Segmentation fault. The patch also fixed a large number of memory leaks in math/float cases.Signed-off-by: Jin Bing Guo <guojb@cn.ibm.com>.

ADMIN_TOOLS addition to default run

I am not sure why runtest/admin_tools was kept outside the perview of LTP default run. I found no issues in running it as normally as other LTP tests. Please let me know if some of you have some problem running it as default. Also included are some changes for running fs_acls tests. Signed-Off-By: Subrata Modak <subrata@linux.vnet.ibm.com>.

If both questions are true and no one has pointed out this issue before now, I've found all of the items which don't follow this behavior: According to the folks in #fedora-devel (airlied, jwb), we shouldn't be using asm/page.h directly, but instead should be accessing everything in page.h via sysconf(2), like so: PAGE_SIZE => sysconf(_SC_PAGE_SIZE). This method is POSIX compatible as per: http://www.opengroup.org/onlinepubs/009695399/functions/sysconf.html. Yes, it is. There are numerous test cases in LTP which use: struct dirent, by including /usr/include/dirent.h. The interesting part is, this guy (/usr/include/dirent.h) in turn includes /usr/include/bits/dirent.h, where the definition of struct resides. Following is the patch which solves this issue along with page.h header file removal from 2.6.25 onwards, reported by Garret earlier. Signed-of-by: Subrata Modak <subrata@linux.vnet.ibm.com>.

IO_* Makefile(s) fixes

In io_cancel01 , io_destroy01, io_getevents01, io_setup01, io_submit01, if the libaio-devel package didn't been installed on the system, some errors would be occured. To fix it, the each Makefile would be modified. Signed-off-by: Jin Bing Guo <guojb@cn.ibm.com>.

FILECAPS fix

MODIFY_LDT Makefile & switch01 fix

The following patch is for script testcases/kernel/ipc/ipc_stress/run_semaphore_test_01.sh. It fixes a test error (line 72) and a bash specific test extension. (lines 72 and 102) that fail to run under Ubuntu (and probably Debian) as /bin/sh points to dash instead of bash (as in Redhat/Fedora). This script would also benefit of a reformatting as it lacks indentation but I wanted to keep the patch simple and I am not familiar with script format style of LTP.Signed-Off-by: Elder Costa <evcosta@dixtal.com.br>.

open10 fix

The following patch is for testcases/kernel/syscalls/open/open10.c. Ubuntu (and I believe, Debian) does not have a nobody group and the program fails to run. I added some lines instead to test for "nogroup" instead which I believe is Debian's equivalent and must do what the program is intended to. Signed-Off-By: Elder Costa <evcosta@dixtal.com.br>.

LTP Changes during AUGUST 2008

Task Title

Task Description

IO-THROTTLE fix

Compile error message occured on ia64 box. You should get a gcc warning on x86: "PAGE_SIZE" redefined. We can avoid the warning: #ifndef PAGE_SIZE #define PAGE_SIZE getpagesize() #endif But normally upper-case macros means constants, but the above macro is not a constant. Shi Weihua <shiwh@cn.fujitsu.com> & Li Zefan <lizf@cn.fujitsu.com>.

fs_inod fix

This patch fixes the fs_inod script. On error-condition it was not setting up proper error values and used to throw up error. Also, it was referring to a non-existent function 'error()'. Now it returns 0 on Success or non-zero value on Failure. I have verified this script on ReadWrite dir and ReadOnly-dir where the tests fail. Signed-Off-By: Veerendra Chandrappa <vechandr@in.ibm.com>.

SETGID16 syscall test addition

Addition of setgid16 syscall tests. I've tried this task. Please put compat_16.h to testcases/kernel/syscalls/setgid. And apply following patch before rebuilding tests. In addition I removed one getgid() invocation in testcases/kernel/syscalls/setgid/setgid02.c because the returned value is not used anywhere in the program. Signed-off-by: Masatake YAMATO <yamato@redhat.com>.

Io-throttle fix

Io-throttle fix

It is surely better to support the old blockio.bandwidth and the new blockio.bandwidth-max interface for now. So, just ignore the previous patch. Support both blockio.bandwidth and the new interface blockio.bandwidth-max, to set i/o limiting rules according to the new userspace->kernel interface (io-throttle v8). In perspective we would like to have also blockio. and width-min and implement a mechanism to guarantee minimum performance levels as well. Signed-off-by: Andrea Righi <righi.andrea@gmail.com>.

utimensat01 fix

utimensat01 give a build error when NR_utimensat is not set because test.h is not included. It also gives a link error because TCID is not defined. This patch fixes these issues. =Signed-off-by: Martin Habets <errandir_news@mph.eclipse.co.uk>.

RO Bind Mount tests addition

Here is the RO Bind mount updated testcase. This script consists of 3 files. test_robind.sh - This is the basis testcase which setups the infrastructure for the ROBind mount fs_ro_test - Which has the different tests to be executed. Readme_ROBind - Explains the different testcases executed. This testcase addresses the earlier comments and has been made more generic. Also will be adding few ioctl syscalls testcases to the fs_ro_test flatfile. As we can append more tests to the flat file fs_ro_test. Signed-Off-By: Veerendra <veeren@linux.vnet.ibm.com>.

EVENTFD() syscall tests addition

HUGEMMAP01 & HUGEMMAP04 fixes

In hugemmap01, huge page size was defined as a macro-definition. #define page_sz ((1UL) << 24) /* Huge page size */ However different architecture may has different huge page size in kernel. Such as : 1. http://lxr.linux.no/linux/include/asm-i386/page.h#L122 #define HPAGE_SHIFT 22 #define HPAGE_SIZE ((1UL) << HPAGE_SHIFT) // the size is 4M 2. http://lxr.linux.no/linux/include/asm-parisc/page.h#L16 #define HPAGE_SHIFT 22 /* 4MB (is this fixed?) */ #define HPAGE_SIZE ((1UL) << HPAGE_SHIFT) 3. PPC: 16M. So read the huge page size for the kernel parameters is reasonable. The solution is to get the huge page size from the /proc/meminfo. Signed-off-by: Jin Bing Guo <guojb@cn.ibm.com>.

test_robind.sh fix

message_queue_test_05 fix

In message_queue_test_05, it planned to allocate 100 message queues for stress testing. But if the system resource of message queue couldn't meet it, it would exit without deleting the allocated message queues. In addition, other test cases couldn't allocate a new message queue any more. This patch addresses this by: 1> Add a cleanup() to remove the created message queues at premature exit. 2> Change the default number of message queues from 100 to 10. Because the maxium on RHEL/SLES/Ubuntu is 16. Signed-Off-By: Jin Bing Guo <guojb@cn.ibm.com>.

GCOV/LCOV fixes

lcov: integrated function coverage patch by Tom Zoernen + sorting function

SEMAPHORE_TEST_01 fix

In semaphore_test_01 case, it wanted to create a semaphore and printed out the semaphore ID for comparison with the output of the 'ipcs -s' command. So it didn't remove the semaphore when exited. Since the resource of semaphore is limited. It's better to write a shell script to perform the comparison and remove the semaphore. I wrote the bash script "testcases/kernel/ipc/ipc_stress/run_semaphore_test_01.sh", and patched the "Makefile" and "runtest/ipc" to run the script. Please clean the semaphore up post patching and before executing tests. Signed-Off-By: Jin Bing Guo <guojb@cn.ibm.com>.

SYNC_FILE_RANGE() syscall tests addition

Intial Addition of sync_file_range() syscall test to LTP. I have developed test cases for sync_file_range() system call which will do the basic sanity (error) checking for the system call. These tests have to be run on 2.6.17 kernel and above. The test cases have been currently tested only on x86 and x86_64 architecture. Also, I have hard coded the system call number in the test case for review purposes and will be later on moving it to linux_syscall_numbers.h file in the LTP framework. The support for PowerPC was provided from 2.6.22 kernel onwards. I had not taken care of it in my previous patch. Now this is addressed. Signed-Off-By: "B. N. Poornima" <poornima@in.ibm.com>.

REALTIME Tests fix

This is a patch from John, written a few months back. I have fixed up a few cosmetic whitespace bits, and have refreshed it so it should apply cleanly to LTP today. Will Schmidt <will_schmidt@vnet.ibm.com>. Comments originally by John Stultz: So I've been trying to go through and review our test cases to make sure we're getting sane data and the tests are really testing what we want. Looking at gtod_latency and gtod_infinite, I was always struck that gtod_infinite always came up with much larger latencies while gtod_latency usually seemed to miss them. Main issues: 1) gtod_latency was not running for long enough, I've upped the iterations by 10x to make sure we get more solid results. 2) gtod_latency was doing too much computation between gtod calls. This means it could miss latencies that occur while it was running. I reworked the data collection loop so the un-measured window is smaller. 3) gtod_infinite was accidentally measuring its own computation in its delay, inflating its values. I cut that logic out. 4) both gtod_latency and gtod_infinite were not running mlocked. this caused background SCHED_OTHER disk access to inject delays, making the results less reliable. Those four issues have been fixed, and I also converted gtod_latency to use clock_gettime() just to be consistent and to give slightly better resolution.

setfsuid04, setresuid04, setreuid07 & setuid04 tests addition for syscalls setuid, setfsuid, setreuid & setresuid

I propose this new test setuid04, setfsuid04, setreuid07 & setresuid04 for the setuid, setfsuid, setreuid & setresuid syscall. The goal if this test is to check the fsuid is correctly handled by the setuid syscall. To do so, the test create a testfile as root with permission 0644, then do a setuid and try to open the file RDWR. This last open must fail since the process with new UID is not allowed to open the file on write. In a second step, the test does a fork to check the fsuid is correctly passed to a son and the son behaves correctly regarding files, i.e. it cannot open on write the test file.

EVENTFD COUNTER OVERFLOW tests addition

This patch adds eventfd counter overflow test cases. I have cleaned up this patch - separated the test cases into its own functions and fixed a few typos. Please ignore the previous patch, and use this cleaned up patch. After the patch is applied, a "make clean" and a "make" should result in a clean build. It works perfectly for me. Anyways I am providing an updated patch with the other linux_syscall_numbers.h removed. As noted in my previous mail, there are two instances of the generated file in the CVS repo now, "include/linux_syscall_numbers.h" and "testcases/kernel/include/linux_syscall_numbers.h".

NUMA Version2 fix

The LTP numa testcases were initially designed for libnuma API in version 1. Building latest LTP (intermediate 20080820) against latest version of libnuma (2.0.2) requires -DNUMA_VERSION1_COMPATIBILITY in the CFLAGS - to switch to to the compatibility interface of libnuma API version 1. There are no libnuma testcases for API version 2 in ltp yet. Currently -DNUMA_VERSION1_COMPATIBILITY will not help for the LTP numa testcase, since the compability interface is missing some interface from version 1: Fix for the VERSION1 compatibility interface got already send to linux-numa list. I hope the libnuma fix got accepted and attached can be applied to LTP soon to fix the build of the LTP numa testcases, when building against libnuma 2.0.2 or greater.

This patch sets the interval equals to the clock precision (retrieved via function clock_getres()), in order to avoid to use a interval smaller than the resolution of the clock.

Time-schedule test fix

In testcases/kernel/sched/tool/time-schedule, it used kill(0, SIGTERM) to terminate the all the processes in the group. However, the progress group leader might be different regarding the different call methods. In interactive call such as pan, it called time-schedule by exec() and setpgrp() as a child process. The time-schedule process would be the process group leader and all the child processes created by it had the same PGID. So the SIGTERM was sent to process group and the exit code got by pan was 0. In non-inactive call such as STAF/STAX, one shell script called the time-schedule directly. The shell script would be the process group leader. So the SIGTERM was also sent to the shell script and the exit code got by STAF/STAX was 143 (128+15). This patch can resolve this Problem.

PSELECT01 fix

Every once in a while, pselect01 fails with the following output: FAIL : Sleep time was incorrect:5 != 6 This is because we expect our sleeps of slightly more than 5 seconds to last at most 5 seconds (if we're uninterrupted, integer truncation will mean this only comes up about 1% of the time).

The testscripts/test_selinux.sh script does not detect if refpolicy should be used or not. The LTP selinux-testsuite test policy uses the can_setcon macro which is not defined in lobal macros of Red Hat Enterprise Linux 4 selinux policy targeted sources. Some Makefile needs minor fixes and enhancements. Ramon de Carvalho Valle <rcvalle@linux.vnet.ibm.com>.

MEM02 fix

I've attached some patches that I created for LTP at work. Most of them simply add command line options to specify the amount of memory/pages to use for tests. However, there's one fix that works around a bug in uClibc's pthread implementation. Allow the amount of memory to be used to be passed as a command-line argument. Matt Fleming <mjf@gentoo.org>.

MMAP1 fix

It can be unsafe to call exit(3) from a signal handler. Call _exit(2) instead. Matt Fleming <mjf@gentoo.org>.

MMSTRESS fix

Allow the number of pages to use for the test to be specified on the command-line. Fix a memory leak. Also, call _exit(2) from child processes which avoids the child calling the atexit functions that the pthread library setup. This fixes an issue where the pthread manager thread would begin exiting at the same time as a child thread. The child thread would run the atexit functions which cause it to wait for a signal to be sent from the thread manager. As the thread manager was trying to exit that signal would never be sent. Calling _exit(2) from the child avoids this whole mess.Matt Fleming <mjf@gentoo.org>.

NANOSLEEP01 fix

Don't place an upper limit on the amount of time a nanosleep(2) call should take. The nanosleep(2) call will suspend execution for _at least_ the specified time, no upper limit is guaranteed. Matt Fleming <mjf@gentoo.org>.

NPTL01 fix

Allow the number of iterations to be specified on the command line. Matt Fleming <mjf@gentoo.org>.

SYSCALL01 fix

Check for SYS_getuid32 and SYS_getgid32, these are the versions provided by some architectures. Matt Fleming <mjf@gentoo.org>.

FILE/DIR Creation fix

There were some mistakes in my previous patch. - wrong mode 0644 for mkdir(). - unnecessary to add 0644 for open() since the flag doesn't include O_CREAT (while it does no harm). By this new patch, they are fixed. Junjiro Okajima <hooanon05@yahoo.co.jp>.

READLINK04 fix

This patch uses strcpy() instead of strcat(). strcat() should only be used when the 'dest' argument is NULL terminated. In this case, path_buffer is not initialised and so may not contain a NULL character. strcpy() will do the right thing and copy the string to the beginning of path_buffer. Matt Fleming <mjf@gentoo.org>.

FILECAPS fix

It eliminates the potential for many false negatives. 1. Use cap_compare to compare capability sets instead of comparing the far less reliable text representations. 2. pI' tests were failing bc I started with empty pI. Fill pI before those tests. 3. Check for libcap-2.11 or later (by checking for cap_compare()). Signed-off-by: Serge Hallyn <serue@us.ibm.com>

LTP-AIO fix

According to the manpages io_submit() can return the value: EAGAIN Insufficient resources are available to queue any iocbs. We should handle this opportunely trying to re-submit the AIO request again. Maybe an even better approach could be to just sleep a bit before trying to re-submit the request.

RT test cases fix for 64-bit LTP forPPC

When compiling powerpc binaries, gcc defaults to 32 bit. To do some tests I needed to have a 64 bit binary. Since I'm using realtime, I modified config.mk as below. My questions: is there any official way to turn LTP in 64bit? If not, what shall we do then? Should LTP default to 32 or native-arch bit? Shall we use something like: "if (uname -m) ..." or use a command line option? Any comment? Gilles. According to man gcc: -m64 Generate code for a 2-bit or 64-bit environment. The 32-bit environment sets int, long and pointer to 32 bits and generates code that runs on any i386 system. The 64-bit environment sets int to 32 bits and long and pointer to 64 bits and generates code for AMD's x86-64 architecture. For darwin only the -m64 option turns off the -fno-pic and -mdynamic-no-pic options. This seems like the right thing to do to me. Gilles, have you confirmed that this doesn't break things on the x86_64 platforms? No Objection from me. --Darren. I've also run the involved tests on an x86_64 machine and it was OK.

This macro reads atomically the 64-bit TSC register. Reading the 64-bit register using two 32-bit instructions sometimes causes wrapping when a clock update appears in between. A single 64-bit read fixes this. Signed-off-by: Gilles Carry <gilles.carry@bull.net>. Cc: Tim Chavez <tinytim@us.ibm.com>. I suppose the right thing to do in the long run would be to rename this function to something more generic: read_hw_clock() or something like that. But I think this patch performs the first step in getting it working on ppc64. Acked-by: Darren Hart <dvhltc@us.ibm.com>.

RT test cases fix for TSC reading cleanup and enhancements

In tsc_minus, changed test (tsc_begin < tsc_end) by (tsc_begin <= tsc_end) since values can be equal as read operations are sometimes very close. Signed-off-by: Gilles Carry <gilles.carry@bull.net>. Cc: Tim Chavez <tinytim@us.ibm.com>. Acked-by: Darren Hart <dvhltc@us.ibm.com>.

Update to OpenHPI 2.12.0 (see www.openhpi.org for more info)

move_pages() test add

Addition of move_pages() syscall tests. The updated patch fixes the warning messages and removes the print_bitmask function (it's not used) which causes build errors on powerpc. Signed-off-by: Vijay Kumar B. <vijaykumar@bravegnu.org>.

linktest.pl fix

The new patch addresses the other error conditions. Like if its not able to create any dir/files in a ReadOnly dir. Also this patch returns the proper return code on success/failure . I have tested this script on ReadWrite dir and ReadOnly dir. Veerendra Chandrappa <vechandr@in.ibm.com>.



LTP Changes during JUNE 2008

Task Title

Task Description

TIMERFD() tests add

These tests were contributed by the timerfd() syscall developer Davide Libenzi <davidel@xmailserver.org>.

CPU & MEMORY HOTPLUG add

CPU and MEMORY HOTPLUG test cases picked up from http://devresources.linux-foundation.org/dev/hotplug/.

CONCURRENCY fix for MREMAP04

This patch fix a concurrency issue in mremap04. The tmp directory the IPC key was build with was destroyed before we destroy the IPC ressource attached to the key. In case of concurency, the same inode id can be reused for another process tmp dir, leading to the generation of the same key. Renaud Lottiaux <Renaud.Lottiaux@kerlabs.com>.

RT fix for START_LATENCY

I spent some time looking at the sched_latency test trying to see why it took so long to start the thread. The java version of the test takes a comparable amount of time to start the thread as it does for each period. The rt-test version was taking an order of magnitude longer. After digging through the java documentation, I found that the RealtimeThread does not actually start executing until the RealtimeThread.waitForNextPeriod() fulfills the time specified in the PeriodicParameters parameter included in its constructor. So all the tests are scheduled to run about 1 second after the threads are created. This gives the system plenty of time to create the thread (a non-realtime code path), set the scheduling parameters and then sleep until the specified run time. The start latency as measured by the test goes something like this:As you can see, the start_latency is a very different measurement in these two cases. In the first, it is basically the initial starting latency as measured by the remainder of the loops. In the second, the execution path of creating the pthread is also counted in the latency. While this might be an important number for us to keep low in our testing, this is not what the java test is measuring. This patch puts the rt-test version in line with the java version. I also think this is reasonable since the rt-wiki says that we should _NEVER_ create threads on the real-time stage. Signed-off-by: Vernon Mauery <vernux@us.ibm.com>.

CONCURRENCY fix for EXECVE05

The following patches fix execve05 for error reporting when execve() succeeds, and exit synchronization in loaded systems. The last two patches are minor cleanups. execve05 checks that execve() fails if a process has opened the file with write access. However, in case the test fails and execve() succeeds, the default binary (test3) has return code 0, which is interpreted as test success. We get output like that: <output>Hello World</output>with return code 0 (success) instead of:<output>execve05 1 FAIL : Failures reported above</output>with return code matching FAIL. This patch simply changes the success return code from 0 to 3, so that execve() success, and thus test failure, can be properly reported. Signed-off-by: Louis Rilling<Louis.Rilling@kerlabs.com>.

CONCURRENCY fix for EXECVE05

The following patches fix execve05 for error reporting when execve() succeeds, and exit synchronization in loaded systems. The last two patches are minor cleanups. In execve05, the first child must keep a file open at least until the second child tries to execve() this file. However the test achieves this with a sleep of 10s, which may fail on loaded systems. This patch replaces this (arbitrary) sleep with a pipe-based synchronization, where the parent notifies the first child once the second child has terminated. Signed-off-by: Louis Rilling <Louis.Rilling@kerlabs.com>.

CONCURRENCY fix for EXECVE05

The following patches fix execve05 for error reporting when execve() succeeds, and exit synchronization in loaded systems. The last two patches are minor cleanups. In a child, calling waitpid() to wait for the death of sibling child is simply non-sense. Moreover in execve05, the second child does not need such synchronization. Remove it. Signed-off-by: Louis Rilling <Louis.Rilling@kerlabs.com>.

CONCURRENCY fix for EXECVE05

The following patches fix execve05 for error reporting when execve() succeeds, and exit synchronization in loaded systems. The last two patches are minor cleanups. cleanup() is reserved for the main test process. In children, call exit() instead. Signed-off-by: Louis Rilling <Louis.Rilling@kerlabs.com>.

SYNC_PIPE fix for lib/libtestsuite.c

This patch fix an issue in the sync_pipe implementation. The problem is the following : after the creation of a pipe we do not close any file descriptor until the end of a test. Let's imagine the following execution :- Process A calls sync_pipe_create - Process A do a fork (creation of process B) - Process A calls sync_pipe_wait ---> Process A blocks on sync_pipe_wait - Process B starts - Process B exits because of an early error. In this case, process A never exits. Since it has not closed its write descriptor to the pipe, the pipe is not considered as broken, thus process A is not notified its son is dead. Thus it will wait forever. Renaud Lottiaux <Renaud.Lottiaux@kerlabs.com>.

COMPILATION fix for include/libtestsuite.h

This patch fixes a compilation warning due to the function "sync_pipe_close" which was not exported. Renaud Lottiaux <Renaud.Lottiaux@kerlabs.com>.

duplicated libtestsuite code removal

After the patch from Roy moveing the libtestsuite code from /testcases/kernel/syscalls/lib to /lib, the code in the old directory has not been removed. Moreover, include PATH in some makefile was still pointing to this old directory. This patch remove libtestsuite code from the old directory and remove deprecated references to this old dir in some Makefiles. Renaud Lottiaux <Renaud.Lottiaux@kerlabs.com>.

Time-schedule01 fix

time-schedule01 failed, because it sent SIGTERM to itself before program exited, so the return value is not 0. This patch makes the main process ignore SIGTERM. Li Zefan <lizf@cn.fujitsu.com>.

FS_BIND Makefile fix

This patch fix the make file of fs_bin test case so that it can be cross-built. Roy Lee <roylee@andestech.com>.

TIMERFD Updates

Add syscall numbers for timerfd syscalls under i386 and x86_64. Roy Lee <roylee@andestech.com>.

TIMERFD Updates

Currently, timerfd01 test case blocks building process for architectures that haven’t prepared for it. This patch modify it to be more generic for all architectures. Roy Lee <roylee@andestech.com>.

RT fix for START_LATENCY

It looks like the only thing that didn't apply was the function declaration. It builds (with a warning) and runs just fine. But here is a patch to fix the warning. Signed-off-by: Vernon Mauery <vernux@us.ibm.com>.

UTIMENSAT() tests addition, testing 99 different scenarios

utimensat() syscall was introduced from linux-2.6.22 onwards. Michael wrote the initial testcases,and, the same is being contributed to LTP under GPLv2. I worked out a patch for this. Though this is not using LTP specific libraries at the moment. But the tests run well and tests 99 separate variations. Michael has written it through itś length and breadth. I generated the code coverage (9.2%) over 2.6.25-gcov kernel, which however was not built with <make allmodconfig> option. Please see it attached along with a draft man page of utimensat(), created by Michael. Let us know how do you feel about this test. We can then go ahead and add this to LTP. Signed-off-by Michael Kerrisk <mtk.manpages@googlemail.com>. Signed-off-by: Subrata Modak<subrata@linux.vnet.ibm.com>.

FS_BIND fix for ia64

FORK12 fix

I execute fork12 test and OMM killer begin send SIGKILL to its children and fork return success always. fork12 hang up in this case, so I create the patch (see attach), which check whether someone child killed and if it occur, return number of forked processes. Andrew Vagin <avagin@gmail.com>.

WRITETEST fix

This patch fixes the writetest.c to return proper status on Failure/Success. At present the return code of the writest.c is 'zero' for both Success and Failure. As per norms non-zero value should be returned for error , so fixing this testcase. Signed off : Veerendra C <vechandr@in.ibm.com>.

MALLOCSTRESS fix

mallocstress stresses the VMM and C library by spawning N threads which malloc blocks of increasing size until malloc returns NULL. It occur because test doesn't wait for all thread started. already started threads begin allocate memory, so pthread_create can return ENOMEM. my patch added this synchronizing. I use semaphore, because it can wait-for-zero unlike pthread_mutex. sorry, forgot set permission in semget, new patch attached. Andrew Vagin <avagin@gmail.com>.

NFSv4-locks fix

Reverting back the changes done to fcntl-lock tests in May 2008 release, as this would have canceled the operation Revision *1.1 *done on the /Mon Sep 11 20:40:52 2006 UTC/ by /mreed10 /which added "A patch that added new functionality into the NFSvf lock tests. -fixes bugs -adds the capability to stress a server with multiple clients" So it is possible to get back to what 's in ltp-full-20080430 and add my fix: You can fix it by replacing in the locktests.c file buf=(char *)malloc(clnt*maxClients); by buf=(char *)malloc(clnt*(maxClients+1)); Signed-off-by: Le Rouzic <aime.le-rouzic@bull.net>.

LTP-Manpage fix

In the manpage for tst_res(3) in the April snapshot it says... tst_brk - Print result message and break remaining test cases tst_brkm -Print result message, including file contents, and break remaining test cases ... at the top of the page. The prototypes and the logic is backwards for the summaries. A patched manpage is provided. Garrett Cooper <yanegomi@gmail.com>.

ns-mcast_join fix

Force the catch_sighup to be volatile in order to overcome an issue due to the compiler optimization. In fact, compiling the test with -Os the catch_sighup variable is not set to 1 into the signal handler. At runtime, the test remain in a loop. No problem compiling without Os or O2.

FS_BIND fix

we have some truble with mapping api functions (such as tst_exit) in bash (./tools/apicmds/ltpapicmd.c). Now this problem may be fixed if added "exit" after tst_exit, but it's temporary. We should redesign this system and describe it in documentation. Andrew Vaggin <avagin@parallels.com>.

signal_test_01 fix

signal_test_01 failed on ia64, the following message outputed: ERROR line: 146 sigaltstack failed: Cannot allocate memory : Cannot allocate memory signal_test_01: IPC Signals TestSuite program And, i found the defined macro STACKSIZE is short on ia64.

check_netem fix

Fixed the way how to run the "tc" command on the remote machine. Otherwise, we always get the following message on the local side: The remote host does not have netem functionality. Signed-off-by: Giuseppe Cavallaro@st.com.

udp4-multi-diffip01 fix

Running the UDP network stress tests on my SH4 target I have had to modify the following scripts: killall_udp_traffic and udp4-multi-diffip01. It deletes the address before setting it to avoid the following error: RTNETLINK answers: File exists; it implies that the test fails. Signed-off-by: Giuseppe Cavallaro <peppe.cavallaro@st.com>.

killall_udp_traffic fix

This modifies the command sent to the remote host just to kill the ns-udpclient script. Indeed, it seems that the previous string always returns 1. Moreover, it adds a new check to verify if the return value is not empty. It could happen, for example, if the RSH returns sometime the following error: poll: protocol failure in circuit setup. Signed-off-by: Giuseppe Cavallaro <peppe.cavallaro@st.com>.

RTNETLINK fix

Attached a new patch just to add the same fixes I provided you for icpm and tcp network stress as well. On SH4 STB with STLinux distribution we are able to run all the network stress tests without any failures. Due to configuration issues we do not run the multi-diffnic tests (because they require plural Network cards for host). It modifies the command sent to the remote host to kill tcp/icmp clients. It also deletes the address before setting it to avoid the following error: "RTNETLINK answers: File exists". This implies that the test fails. Signed-off-by: Giuseppe Cavallaro <peppe.cavallaro@st.com>.

Process Event Connector tests add

Addition of Initial set of Process Event Connectors by Li Zefan. Process event connector is a netlink connector that reports process events to userspace, and currently we have 5 kinds of process events, i.e. fork, exit, exec, uid, gid. There are total 5 test cases to test its functionality. But the test is not run by default, because I don't find a way to decide whether the underlying kernel supports this feather or not. Signed-off-by: Li Zefan <lizf@cn.fujitsu.com>.

Process Event Connector tests modify

Here it is. Based on my last patch. - building failure on 2.6.16 should be fixed - fix "make install" if kernel version<2.6.15 - abort tests if kernel version < 2.6.15 Signed-off-by: Li Zefan <lizf@cn.fujitsu.com>.

io_cancel() tests add

This was ported from the Crackerjack Project by Masatake YAMATO <yamato@redhat.com>.

io_cancel() tests Modify

I'd like to use the mechanism you introduced in io_* testcases. So I've made 'io_cancel' string in the script and Makefile a variable to avoid mistake. I made the patch from testcases/kernel/syscalls/io_cancel/Makefile, not from ltp/testcases/kernel/syscalls/io_cancel/Makefile. Is this acceptable. CVS reports like testcases/kernel/syscalls/io_cancel/Makefile. Signed-off-by: Masatake YAMATO <yamato@redhat.com>.

hackbench tests add

hackbench tests the Linux scheduler. Initial test was written by Rusty Russell <rusty@rustcorp.com.au>. Later modified by Pierre Peiffer <pierre.peiffer@bull.net>, Ingo Molnar <mingo@elte.hu>, Arjan van de Ven <arjan@infradead.org>, "Zhang, Yanmin" <yanmin_zhang@linux.intel.com>, Nathan Lynch <ntl@pobox.com> and others. Included in LTP by Subrata Modak<subrata@linux.vnet.ibm.com>, after Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>.

BASIC_RPC fix

I am proposing with the joined patch to allow the suite to be able the run the previous rpc tests (called now basic_tests). It needs to resolve some issues in the new "tirpc part" before allowing the suite to launch it again. Le Rouzic <aime.le-rouzic@bull.net>

MMAP01 & SHMT09 update

The fixed address passed to mmap() should be aligned to the value of SHMLBA as defined in sys/shm.h. See Documentation/cachetlb.txt in the kernel for the explanation behind this.

Update to OpenHPI 2.10.2

RT Linux Test update

This series of patches allows the pass/fail criteria to be defined in a command line argument.(-c) librttest.c declares a global variable pass_criteria which is defined as extern in librttest.h The parsing is done as usual in function rt_init. To be as comprehensive as possible, pass_criteria is declared as a double so some tests need to cast it to integer before use. The below tests have been modified to use this new feature: sched_latency.c, tc-2.c, hrtimer-prio.c, pi_perf.c, async_handler.c and async_handler_jk.c, matrix_mult.c, pthread_kill_latency.c, prio-preempt.c, Notes: - default values have not been changed, - it is always tests' responsibility to handle default values, - to have a consistent interface, periodic_cpu_load_single.c's arg "-c howmanyloops" was changed to -l. This patch series also features a minor fix in librttest.c in args parsing switch case. In a next series, I will provide a feature that parses a single config file including the pass/fail criteria for all tests. This will make life easier for people wanting to define test profiles. Gilles Carry <gilles.carry@bull.net>.

HUGETLB update

It seems that hugeshmctl01 doesn't free some hugetlb pages when it fails. ps shows that there is still an instance of hugeshmctl01 left even if hugeshmctl01 is not running which may attach some hugetlb pages. The problem is due to the arbitrary usleep time in hugeshmctl01 which results in incorrect execution order. The intention of the sleep time is to ensure the children call shmat() and pause() before the parent checks shm status and calls stat_cleanup(). But there is no absolute assurance that this sleep always works. In the failure above, the last child process forked by the parent may not run and call shmat() immediately after it's created. When the parent checks shm status, it finds only 3 child attaching the shm instead of 4, so it reports the failure. And then it calls stat_cleanup() to send SIGUSR1 to all children, but since the last child hasn't called pause() yet, SIGUSR1 is handled before pause(). When the last child calls pause(), since there is no further signal to wake it up, it sleeps forever. patch to ensure children can receive and handle SIGUSR1 from parent in pause(). The patch is not to change the arbitrary usleep time since any time is arbitrary though a large time is more acceptable. The patch is to use sigprocmask() to block SIGUSR1 before children sleep for SIGUSR1 from parent, and then call sigsuspend() to unblock SIGUSR1 and sleep for SIGUSR1. By doing so, we may avoid the infinite sleep and keeping attached shm forever so that affect other hugetlb test. In parent process, aonther sigprocmask() is called before usleep(). This has the same effect of sleep more time. By, shenlinf <shenlinf@cn.ibm.com>

HUGETLB update

I am testing ltp-full-20080430. When I execute hugemmap04, hugemmap01 is shown in the output which makes the output confusing. patch to fix the bad name. By, shenlinf <shenlinf@cn.ibm.com>

SOCKIOCTL update

Attached is a fixed patch to be applied over 1.8 in cvs. Previous patch mistook the return of mknod() for a file descriptor and after the first iteration, test was using the wrong (closed) file descriptor. This patch uses the correct file descriptor. Thanks Rishikesh for catching my error. By, Henry Yei <hyei@mvista.com>

RT Linux Test update

The problem is because some of the realtime tests can't be compiled on older distros. We will have to fix this 'properly', taking into account the kernel and glibc versions, as well as the architecture. Until we do that, can we disable compiling realtime tests by default? Below is a patch that can do it. Signed-off-by: Sripathi Kodi <sripathik@in.ibm.com>

MALLOCSTRESS fix

Addition of FILESYSTEM BIND MOUNT tests or SHAREDSUBTREE test cases to LTP

DIOTEST4 fix

The fixed address passed to mmap() should be aligned to the value of SHMLBA as defined in sys/shm.h (The same fix can be found in the mmap01 case earlier sent from Martin Habets). By, Roy Lee <roylee17@gmail.com>.

SHMT fixes

This patch modifies testcases to attach their shm segment to addresses chosen by system instead of arch-dependent ones. I looked into the history of these testcases, but couldn't find the reason why they specified arch-dependent addresses in the first place. If it has something to do with the page coloring issue, SHMLBA should be in some manners instead of defining arch-dependent addresses. Tested successfully on ia64, ppc64, x86_64, s390x & i386 by Subrata Modak <subrata@linux.vnet.ibm.com>, and by Martin Habets <errandir_news@mph.eclipse.co.uk> on sparc32.

RT Linux Test update

These patches will allow for the plotting of the max over time in discrete segments, rather than as a monotonically increasing value, while maintaining the original behavior by default. The existing test has an infinite window and report the new max each time it is increased.

Signed-off-by: Darren Hart <dvhltc@us.ibm.com>. Acked-by: John Stultz <johnstul@us.ibm.com>.

SHMT05 fix

I see Roy's patch was already checked in. In principle I agree with the patch, but a few things are wrong now and IMHO does not fulfill what it should test any longer. shm05.c -> see my (untested!!!) patch below. Some architectures can only map at specific offsets. Current version "sucessfully" fails, because e.g. hppa can't map at cp+4096. So, it's not failing because the memory regions overlap, although that was intended to be tested...shm06.c now does basically the same test as shm04.c ?!? Doesn't make sense... I would revert the patch for shm06, but maybe others think different???? Other patches seem ok, although I haven't looked too deep into them yet... Helge Deller <deller@gmx.de>.

SHMT06 fix

Roy Lee <roylee17@gmail.com> wrote: Your patch looks good to me. It does what I'm intended but failed to do; eliminating explicit arch-dependent code without breaking logics. How about merge the scenario of shm06 into shm04, and then eliminate shm06? Modify shm04 to attach the same segment _twice_ to the child's address space. In this case, the first returned address should be the same as where the parent attaches its segment to while the second returned address should be different. Helge Deller <deller@gmx.de> wrote: Yes, this is probably the best idea. Alternatively, just leave shm04 as-is, and do the twice- mapping you mentioned above in shm06. This way we'd keep two simple tests. Roy Lee <roylee17@gmail.com> wrote back: Here's the patch for the shmt06 according to Helge's recommandation, please help review it.

Added Default Log File generation capability for LTP

SHMAT01 & SHMAT02 fix

Both of the above test cases has similar issue to shmt/mmap series. This patch removes the non-aligned addresses explicitly coded for different architectures by: 1) probing an available address by a pair of shmat/shmdt calls, and, 2) replaceing the addr with offset in the struct test_case_t. By, Roy Lee <roylee17@gmail.com>

PAN/PAN.c fix

The "pan/pan" would failed in segmentation fault with a wrong option "-f command-file". Among the options, the "/tmp/test" does not exist. The solution is to add condition judgements before use the pointer. To execute pan/pan with option "-p" will occurs Segmentation fault. The reason is that it not appends the "-l" option to pan to open the "logfile" for writing log. Just add a condition judgement to fix it. Signed-off-by: Jin Bing Guo <guojb@cn.ibm.com>.

sync_pipes API fix

Make-sync_pipe-API-more-generic-and-update-related.patch. Put-libtestsuite-to-a-more-common-place.patch. Roy Lee <roylee17@gmail.com> noted: Referring to the sync_pipes API, create_sync_pipes(), wait_son_startup(), notify_startup(), which is defined in the: testcases/kernel/syscalls/lib/libtestsuite.[ch], I found the new sync_pipes API very convenient to synchronize processes. However the naming might pose some semantic restrictions on their usages. Since it can be used for making parent to wait child, and vice versa, perhaps a better naming should be used. For example: sync_pipes_create (), sync_pipes_wait (), sync_pipes_notify(), other names will be good as long as they don't assume the caller is child or parent. Furthermore, since it is also suitable for being used in common test cases, moving it outside the syscalls's directory to a more common place might be a good idea. Renaud Lottiaux <Renaud.Lottiaux@kerlabs.com> noted: I fully agree with your remarks. But if you want to make these functions more generic, it should be possible to call sync_pipe_wait / notify several times, which is not possible in the current code since I close file descriptors in these functions. A quite simple solution is to keep these file descriptors opened, and to add a function to close them or simply let these file descriptors being closed by libC or kernel at process end. Signed-off-by: Roy Lee <roylee17@gmail.com>.

SHMAT01 & SHMAT02 fix

RT Linux Test update

Profiled Tests: Basically this was done to enhance the pass/fail criteria usage and allow the user to setup tests configurations according to specific needs. Imagine a test series that may validate a hardware for some latencies (case #1) while another series would validate other criteria (case #2). The same test used in situation #1 will not have the same configuration (arguments) in situation #2. Scripting has to be done for this to achieve. The profile system does this for you. You just have to configure. Not only pass/fail criteria can be set since the profile system simply runs command lines defined in profiles. So any argument can be choosen. ie: a profile can define criteria for tests with or without saving statistics (-s) or simulate jvm (-j). A profile comes as a single file so it is easy to copy from a test machine to another. With this patch, profiles can be used either for test global run (./run.sh) or for an individual directory (./run_auto.sh). For more information, read doc/AUTOMATED_RUN. This patch is intentionnally global as splitting changes would not make sense. This includes: - changes of scripts for automated tests to feature profiles, - individual changes for tests using automation, - a default profile (to be used as an example), - documentation writing/modifying.

CONCURRENCY Fix for msgctl06

This patch fix a concurrency issue in msgctl06. The tmp directory the IPC key was build with was destroyed before we destroy the IPC ressource attached to the key. In case of concurency, the same inode id can be reused for another process tmp dir, leading to the generation of the same key. Regards Renaud Lottiaux <Renaud.Lottiaux@kerlabs.com>.

PTRACE03 Fix

I got failures on ptrace03 because the latest kernel allows init process to be traced. Commit is: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff; h=00cd5c37afd5f431ac186dd131705048c0a11fdb, See the discussion in LKML: http://marc.info/?t=120628018600001. So we should not execute this test case if the kernel version is above 2.6.25. Signed-off-by: Li Zefan lizf@cn.fujitsu.com>.

CONCURRENCY Fix for execve02

execve02 checks that execve() fails if the caller does not have executable permission on the file. However, in case the test fails and execve() succeeds, the default binary (test3) has return code 0, which is interpreted as test success. We get output like that: <output> Hello World </output> with return code 0 (success) instead of: <output> execve02 1 FAIL : Failures reported above </output> with return code matching FAIL. This patch simply changes the success return code from 0 to 3, so that execve() success, and thus test failure, can be properly reported. Signed-off-by: Louis Rilling <Louis.Rilling@kerlabs.com>

I got the following failure: adjtimex02 4 FAIL : Test Failed, adjtimex()returned 5, errno = 0 : Success,= adjtimex02 5 FAIL : Test Failed, adjtimex()returned 5, errno = 0 : Success. This is because the latest kernel normalizes buf.offset value if it is outside the acceptable range.

signal_test_01 fix

According to man sigpause : int sigpause(int sigmask); /* BSD */, int sigpause(int sig); /* System V / Unix95 */ [...] Linux Notes On Linux, this routine is a system call only on the Sparc (sparc64) architecture. Libc4 and libc5 only know about the BSD version. Glibc uses the BSD version if the _BSD_SOURCE feature test macro is defined and none of _POSIX_SOURCE, _POSIX_C_SOURCE, _XOPEN_SOURCE, _GNU_SOURCE, or _SVID_SOURCE is defined. The System V version is used if _XOPEN_SOURCE is defined. Since the _BSD_SOURCE_ is not defined for LTP testcases, rather they define _XOPEN_SOURCE_, the behaviour is System V, where they expect a signal number instead of signal mask.

RT Test Fix

Ankita Proposed that: We have been seeing failures in the prio-wake testcase for a while now. Digged closer into the testcase to find if there was an error lurking in the testcase itself. Did hit a few, which this patch aims to fix. But the failures persist, indicating that something is amiss in the kernel. This patch does the following: o Make the output of the test more readable. It is now time ordered. o Bases the pass/fail not only on the order in which the waking up threads update the 'wakeup.arr' but also on the time they woke up. This reduced chances of error. o Remove an extra lock and unlock on mutex when updating wakeup.arr. Chirag Jog <chirag@linux.vnet.ibm.com> commented: I am not convinced that adding a check for wake up time is going to reduce the chances for error. Whichever thread wakes up first, takes the lock,updates priority and time fields. Hence the time field will always be updated in wakeup order. So this is not really adding another useful check. I am ready to be conviced otherwise :) Ankita Replied: Yep I agree that now it would not make any difference. But before this patch, we were unlocking the mutex after only updating the running_threads and noting down the wakeup time and try and acquire the lock again to update the wakeup order in wakeup.arr So, there were chances the wakeup time did not match the order in which the wakeup.arr was updated. But yes, with the lock changes, this change would not be required. Shall send the patch again. Thanks for the review :-). So here is the updated patch which takes Chirag's comments into account.

LTP Changes during APRIL 2008



Task Title

Task Description

LTP-DEVEL RPM

Addition of SPEC File for creation of LTP-DEVEL RPMs on various Architectures for Standalone development of LTP Unit Testcase. Contributed by George Kraft <gk4@us.ibm.com>

RT Linux Test update

This patch should solve the problem of RT Linux Compilation Failure on various Architectures. It just avoids the compilation of realtime tests on a non (x86,ppc) arch. Assumption: uname -m doesn't contain 86/ppc on any arch except the x86 and ppc. Signed-Off-By: Chirag <chirag@linux.vnet.ibm.com>

Se-linux Test suite Update

Previously I was under the impression that selinux test was not cleaning up properly. I don't believe that to be the case. I must have been mistaken. Here is a patch for the allow_domain_fd_use boolean issue in 5.2, by, Jeff Burke <jburke@redhat.com>

Se-linux Test suite Update

This patch, which is independent of Jeff's patch, updates the selinux testsuite to run under Fedora 9, and does no harm on Fedora 8. While creating this, I noticed two other things that ultimately need fixing: 1) The sbin_deprecated.patch adds domain_dyntrans_type() to all the test domains. If that was truly desired, we should just put it into unconfined_runs_test(). But it shouldn't be necessary -only the test_dyntrans.te and test_dyntrace.te domains should require permissions for dynamic transitions. I'll let Serge confirm that. 2) The test scripts are presently relabeling /tmp to test_file_t for the duration of the test. That's insane - it could break any other running process that tries to access /tmp during the test. That was not part of our original selinux testsuite and seems to have been introduced when IBM ported it to LTP. If you are worried about lacking search permission to /tmp in the test domains, then create your own private /test directory or something. Or just give all test domains permission to search tmp either via unconfined_runs_test() or in test_global.te using the testdomain attribute. Those don't need to be fixed though for this patch to be merged. Also, I noticed some new failures in the tests due to latest Fedora policies giving all domains search permission to all directories. Not sure if that was intentional - sent a separate note to Dan about that.

Se-linux Test suite Update

Ok here is a first small patch to stop relabeling /tmp as Stephen suggested. It should be no more complicated to get rid of the unneeded dyntrans_types, but I messed up somewhere generating the patch and subsequent test bombed. So I'll just do that next week or whenever this patch hits cvs (for simplicity). Subject: selinux testsuite: don't relabel /tmp. There's no need for the selinux testsuite to relabel /tmp for the duration of the test. It uses /tmp/selinux anyway. Just need to be sure to have search perms to tmp_t.

TCPDUMP01 Fix

This turned out to be a test case problem, where it fails to identify the correct backbone network interface to use for the test. But there is an option already provided for the interface to be specified while invoking the test. Here, eth1 is the backbone interface and hence if the test is invoked like 'IFNAME=eth1 ./tcpdump01' it will pass. But it relies on DNS lookup and requires the IP to be configured accordingly.

execve05 concurrency fix

In the expected scenario, it attempts to execve(2) a file which is being opened by another process for writing fails with ETXTBS. On a loaded system, however, the child which does execve might get access to the file before the other child which opens it and result in a unexpected opening fail. By Roy Lee <roylee17@gmail.com>

SGI Common Criteria CAPP/LSPP EAL4+ certification test suite Release

Release of gcov-kernel patches for Linux 2.6.25 to LTP and LKML

execve05 concurrency fix

I think there is a problem with the previous patch. Since you call the wait_son_startup() function after the fork() and before the test on the PID variable, the father AND the son will wait on the pipe, leading to a dead-lock. I suggest to move the wait_son_startup() calls after the pid test. Renaud Lottiaux <Renaud.Lottiaux@kerlabs.com>. Changes by Roy Lee <roylee17@gmail.com>.

Execve02 concurrency fix

This patch fix a concurrency issue in execve02. In case of concurrent executions, all tasks was using the same file, changing its mode and leading to invalid mode for some of them. This patch creates a private tmp directory for each task, copies the test file in it and performs all the tests using this private file. Regards Renaud Lottiaux <Renaud.Lottiaux@kerlabs.com>

Ftruncate04 concurrency fix

This patch fixes a concurrency issue in ftruncate04. In the expected scenario, child should hold the lock of the file before parent access it. On a loaded system, however, the parent might access the file before the child, hence resulting in a unexpected 'open fail'. By, Roy Lee <roylee17@gmail.com>.

POSIXFADVISE fix

The following patch and all others that were submitted in Feb, 2008 pertaining to "NR_fadvise64" seem to break ARM builds of ltp as the arm does not have NR_fadvise64 defined. I suspect there should be #ifndef NR_fadvise64 #define NR_fadvise64 0 in each of the files that the patches were added. By, Shane Volpe <shanevolpe@gmail.com>

SYSFS fix

The Linux port I run on LTP has a minimal set of system calls. It currently does not implement the sysfs system call so I'd like to disable the tests for this system call - at the moment they will fail to compile because NR_sysfs is undefined. Is there an idiomatic way of doing this? I can either prevent the test compiling completely somehow in the Makefile (e.g. as modify_ldt does) or make the test compile but return BROK perhaps. Attached is a patch to implement a strategy like this one. By Will Newton <will.newton@gmail.com>

F00f fix

Executing f00f testcase in x86 Xeon machines, it failed returning SIGSEGV: # ./f00f f00f 0 INFO : Testing for proper f00f instruction handling. Segmentation fault. Searching for this issue, I found an old thread in ltp-list discussing broken test-cases, where Jeff Burke raise this problem with f00f failing on systems that have the NX bit. But, according to the flags reported in /proc/cpuinfo, the machines where i'm running this testcase seems not to have this NX bit enabled. On /proc/cpuinfo, we also have this line "f00f_bug: no". Would it be useful to select if this testcase should be executed or not? These machines are running a kernel compiled with processor family "Pentium-Pro" (CONFIG_M686=y), which, in according to the kernel config help, "disables the init-time guard against the f00f bug found in earlier Pentiums". Here i have created a patch that seems to fix the testcase using an inline assembly. By, Edjunior Barbosa Machado <emachado@linux.vnet.ibm.com>

Nptl01 fix

nptl01 looks to have an operator precedence bug in it that prevents the output being done at appropriate times. With this patch you should get 10 lines of output, one every 10000 loops, rather than 10 lines of output, one for each of the first 10 loops. By, Will Newton <will.newton@gmail.com>.

RT Linux Update

I believe we had written this test to debug the other test with a lower overhead clocksource. Unfortunately, the tsc is x86 specific, isn't consistent across CPUs on certain systems, and can have it's frequency changed depending on by power states. For all those reasons this test can simply be removed from the LTP.

FLOAT_BESSEL Update

The float_bessel testcases, as a matter of fact, all float_* testcases seem to fail when multiple instances are run concurrently. The failures occur because file sizes don't match or because the number of bytes read don't match the file size. This can be attributed to the parallel instance reading a file before the write to it (by another instance) has completed. In such situations, either the file size has not been updated in the inode header or the file size has been updated but the file's write operation has not been updated completely. To fix this concurrency problem, my suggestion is to check for an existing instance and wait for it to finish before beginning the current instance. Any other concurrency resolution technique may complicate matters. A message to the console indicating such a decision might be added.

In this case, due to the large number of running processes and scheduler decisions, the father task can exit before its sons. Thus, leading to the removal of a file still opened by a son... NFS don't like that, Signed-off-by: Renaud Loittiaux <Renaud.Lottiaux@kerlabs.com>

CONCURRENCY Fixes

Fixing a concurrency issue in semctl07.c. This test was using a key hard coded in the source code, leading to conflicts with other instances of the same test. This patch also add a cleanup of the semid in case of failure during the test, by, Renaud Lottiaux <Renaud.Lottiaux@kerlabs.com>

CONCURRENCY Fixes

Fixing a concurrency issue in semop02.c. The now, well known issue due to a second key badly created, by, Renaud Lottiaux <Renaud.Lottiaux@kerlabs.com>

CONCURRENCY Fixes

Fixes a concurrency issue in semctl01. This test was using usleep to synchronize tasks. On a heavily loaded system, this synchronization is not enough to ensure execution correctness. This patch is a bit more intrusive than my previous ones. Patch content : * Define 2 new functions in kernel/syscalls/lib/libtestsuite.c, used to synchronize a father and a son using pipes. - create_sync_pipes: create a pair of pipes used for the synchronization,- wait_son_startup: function used in the father to wait for its son to start ts execution, - notify_startup: function used in the son to notify it has started its execution, * Add a kernel/syscalls/lib/libtestsuite.h file to cleanly export newly defines functions, * Fix the semctl01test. The idea used to synchronize :- For each task created, the father waits for the son to start its execution using the newly define functions, - After the last son has been created, the father do a sleep(1) to give time to the sons to execute the semop function, The final sleep does not guaranty the sons will have time to do the semop. On a REALLY heavily loaded system, this will still fail... The only solution I see to be sure the son is really blocked on the semop before the father continue its execution it to use the wchan info from /proc/<pid>/wchan file..., by, Renaud Lottiaux <Renaud.Lottiaux@kerlabs.com>

NFX ISSUE Fix

Fixing some NFS issue(s), by, Renaud Lottiaux <Renaud.Lottiaux@kerlabs.com>

NFX ISSUE Fix

Fix directory remove issue on NFS. On NFS unlinking AND closing all files in a directory is mandaroty before unlinking this directory. This also fix a write in a invalid array entry. fds[5] does not exist since we only defines 5 tests., by, Renaud Lottiaux <Renaud.Lottiaux@kerlabs.com>

Makefile Insonsistency Fix

LTP is failing to compile with GCC 3.3.3 due to Makefile's inconsistency. SLES9.X distros are affected by this problem. This patch fixes how /lib/ipcmsg.h header file is referenced. It works fine with GCC 3.4.X, however, compiling headers doesn't make any sense to me. Signed-off-by: Rafael Folco <rfolco@linux.vnet.ibm.com>

DUP203 Fix

Fixes the hardcoded file descriptor in the second testcase within dup203.c . Instead of assuming file descriptor 10 is closed, the fix explicitly opens and closes a file descriptor before using it as the second argument of dup2(). We saw issues on some environments where dup2(10,10) was being called, which this fixes, by, Henry Wei <hyei@mvista.com>

RT Linux Test Update

We have seen that prio_preempt testcase that is part of realtime tests occasionally hangs. This can be easily recreated on a 8-cpu system, but can be recreated on a 4-cpu system as well when run for a number of iterations. The problem occurs because the first worker thread sometimes fails to call cond_wait on the condvar through which the master thread signals it to start. Since the first thread needs to start the chain of signalling from then on, all other threads just sit in a cond_wait without ever being woken up. The fix is to have a barrier to ensure that the first worker thread doesn't miss the cond_signal. I have tested this patch by running 10s of thousands of iterations of the testcase. Without the patch I can recreate the problem fairly easily, by, Sripathi Kodi <sripathik@in.ibm.com>

DIOTEST04 update

Fix 'reading beyond file size' testcase in diotest4. Something goes wrong if we are allowed to read, or, we are not allowed to read, but we've got unexpected errno, by, Anton Gladkov <agladkov@parallels.com>

TI-RPC Tests Addittion

Initial Set of TI-RPC test Cases addition to LTP, by, Aurélien Charbon <aurelien.charbon@ext.bull.net>

LTP Intermediate Release for MARCH 2008

MISC updates

The idea of the patch is "to make things that should be extern, extern". The means to do this are: 1. Explicitly declaring variables extern in some places. 2. Defining _USC_LIB_ where appropriate. by, Will Newton <will.newton@gmail.com>

RT Linux Test Update

Add 2 scripts for detecting features used by some tests, namely: - support for pthread_mutexattr_setprotocol(..., PTHREAD_PRIO_INHERIT) - support for pthread_mutexattr_setrobust_np() Signed-off-by: Sebastien Dugue <sebastien.dugue@bull.net>

RT Linux Test Update

'RT Linux Test Update

Fix by Michael Olbrich <m.olbrich@pengutronix.de>, as, Sebastien´s Patch [[PATCH 3/3] [Realtime] Remove autotools specific stuff] applied on 24/03/2008 breaks this script.

RT Linux Test Update

Usually the cross compiler is set from the toplevel directory by setting the CROSS_COMPILER variable. This makefile tries to overwrite it, but wrong. It is also possible to push in CFLAGS from the toplevel by using CROSS_CFLAGS. We should use these here as well. Finally, LDFLAGS are set here but not used by the makefiles. Moving the posix libs to LDLIBS makes it build. Signed-off-by: Robert Schwebel <r.schwebel@pengutronix.de>

RT Linux Test Update

This patch updates the matrix_mult testcase to closely follow the JVM in the concurrent case. So in the concurrent case we have 'numcpus-1' concurrent threads that are handed out work by the main thread and once we run out of concurrent threads, the main thread does the work itself. Signed-off-by: Dinakar Guniguntala <dino@in.ibm.com>

MMAP1 update

mmap1.c:524: warning: format '%ld' expects type 'long int', but argument 3 has type 'double' which actually prints as: WARNING: bad argument. Using default 1125899906842624

DISKTEST update

Fix disktest printf format warnings (on Linux; no idea about Windows): childmain.c:443: warning: format '%d' expects type 'int', but argument 4 has type 'size_t' childmain.c:443: warning: format '%X' expects type 'unsigned int', but argument 5 has type 'size_t' childmain.c:445: warning: format '%d' expects type 'int', but argument 6 has type 'size_t' childmain.c:448: warning: format '%d' expects type 'int', but argument 6 has type 'size_t' childmain.c:451: warning: format '%d' expects type 'int', but argument 6 has type 'size_t' Signed-off-by: Randy Dunlap <randy.dunlap@oracle.com>

SYSLOGTST Update

All the syslog test cases in ltp-full-20080131 are failing for RHEL4U5 on x3850 M2 architecture. The syslogtst is failing because when only 1 argument is passed to syslogtst the condition in the test case fails to deal with it. I have tested the failed tests cases after applying the patch on the same architecture(x3850M2) and found its passing. Signed-off-by : Vinay Sridhar <vinaysridhar@in.ibm.com>

INOTIFY02 Fix

The filename arguments in some output messages are wrong. Signed-off-by: Li Zefan <lizf@cn.fujitsu.com>

RT Linux Test Update

Fixes a minor issue with pi_perf testcase (testcases/realtime/func/). The wait_dat is intended to measure the amount of time it took for the high priority thread to actually obtain the lock from the time it was released by the low priority thread. The patch fixes this computation to measure it more accurately. The PASS/FAIL computation is unaffected. Signed-off-by: Ankita Garg <ankita@in.ibm.com>, Acked-by: Sripathi Kodi <sripathik@in.ibm.com>

VMSPLICE01 Fix

The vmsplice01 testcase in LTP failed when run over machines with NFS mount. However after I examined the test case I found that the testcase performs vmsplice() and splice() system calls and it was only splice() that caused the failure. After discussing with Subrata, we had decided that the fact that vmsplice() succeeds must be displayed before checking if the testcase is running over NFS and exiting. Hence I have prepared a patch with the above details taken care of. Signed-off-by : Vinay Sridhar <vinaysridhar@in.ibm.com>

FACCESSAT01 and FCHMODAT01 fixes

faccessat01 and fchmodat01 did not test the AT_FDCWD tests, but assigned fds[5]. I made them work, patch attached. btw, readlinkat01 is also buggy, but I have not yet come around to fixing it. By, Marcus Meissner <marcusmeissner@users.sourceforge.net>

NFTW64 fix

Some newer glibcs do not like sprintf() printing a string into itself and loop. By, Marcus Meissner <marcusmeissner@users.sourceforge.net>

MISSING DECLARATION fixes

some more "variable is used uninitialized" warnings fixed with this patch, by, Marcus Meissner <marcusmeissner@users.sourceforge.net>DECLARATION fixes

GCC WARNINGS fixes

This patch fixes some compiler warnings spit out by newer GCCs and fortify source (mostly some initialisations and return value checking),by, Marcus Meissner <marcusmeissner@users.sourceforge.net>

WAITPID fixes

Various waitpid tests print the PID of the wrong array. fork_kid_pid[j] is accessed just past the end of the fork_kid_pid array, so it is better to use wait_kid_pid[i] instead, by, Marcus Meissner <marcusmeissner@users.sourceforge.net>

COMPILE ERROR fixes

When I was compiling ltp-full-20080229/kernel/module/, error occured. The error like this: ... scripts/Makefile.build:46: *** CFLAGS was changed in "ltp-full-20080229/testcases/kernel/module/delete_module/Makefile". Fix it to use EXTRA_CFLAGS. Stop. The reason is: When we build an External module, we should use EXTRA_CFLAGS, not CFLAGS. In detail please refer to Documentation/kbuild/modules.txt. In addition,there are some trashy "include" such as: "#include <asm/atomic.h>" in delete_module01.c "#include <linux/config.h>" in dummy_del_mod.c The following patch solves these problems: Signed-off-by: Wang Fang <wangf@cn.fujitsu.com>

LINK ERROR fixes

The ltp-full-20080229/testcases/kernel/module/delete_module/Makefile will do this: @set -e; for i in $(MODULES); do ln -f $$i /tmp/$$i ;done If the ltp directory and /tmp are not in the same device, an error occurs: ln: creating hard link /tmp/xxx' => xxx': Invalid cross-device link I suffer from this. The patch as follows: Signed-off-by: Wang Fang <wangf@cn.fujitsu.com>

DATA DISPLAY fixes

The memsize is specified by the user in Mb, but it is converted to Kb in the script, so we should convert it to Mb in the output. The following patch solves this problem: Signed-off-by: Wang Fang <wangf@cn.fujitsu.com>

INOTIFY02 fixes

The 9th testcase of inotify02 failed due to event coalescence. We fix this by moving the IN_DELETE test in between of the 2 IN_MOVE_SELF events. Also add the test for =event coalescence. Signed-off-by: Li Zefan <lizf@cn.fujitsu.com>

LTP Disktest Update

Disktest application update to version 1.4.2, by, Brent Yardley <yardleyb@us.ibm.com>

PID Namespace Update

Pid Namespace were getting segmentation fault while running on -mm kernel. After debugging by container development team they found the exact root cause. The Page_Size was reset, by, "Rishikesh K. Rajak" <risrajak@linux.vnet.ibm.com>

remap_file_pages02 update

Based on the discussion at LKML (http://lkml.org/lkml/2007/11/29/325), Ricardo Salveti de Araujo <rsalveti@linux.vnet.ibm.com> removed the test case that verifies if the pgoff is "valid"

Mprotect02 fix

The problem was the position of the parenthesis, which made "fd" receive the result of the < (lower than) operation, instead of the actual return value from open. This implicates a lot of trouble in any subsequent reference to fd, used in write and mmap. Because of this, mmap was returning an error number (ENODEV), instead of a valid memory address, which created the mprotect trouble. Fix by Jose Otavio Rizzatti Ferreira <joseferr@br.ibm.com>

Sysconf01 fix

Patrick Kirsch <pkirsch@suse.de> personally thinks, it would be better to print out the "actual" return code from sysconf call instead of the errno, which may lead to confusion, because the actual return code from the failing sysconf is probably not 0 (as errno is defined in previous context).

RT Linux Update

Pcllib (syscall) Update

Remove compiled files, by, Mike Frysinger <vapier@users.sourceforge.net>

Pcllib (syscall) Update

punt compiled files, by, Mike Frysinger <vapier@users.sourceforge.net>

FALLOCATE fix

This will address the problem until distros update with latest glibc which has fallocate implementation. This is not extensively tested and built with some assumption like o we are testing on x86* and ppc* archs o on 64 bit machine we will always see 64 bit kernel running by, Nagesh Sharyathi <sharyathi@in.ibm.com>

IPC-MSGCTL Fix

Since msgmni now scales to the memory size, it may reach big values. To avoid forking 2*msgmni processes and create msgmni msg queues, do not take msgmni from procfs anymore. Just define it as 16 (which is the MSGMNI constant value in linux/msg.h) Also fixed the Makefiles in ipc/lib and ipc/msgctl: there was no dependency on the lib/ipc*.h header files.

LCOV Fix

lcov: fix error when trying to use genhtml -b genhtml fails when the data file contains an entry which is not found in the base file, by, Peter Oberparleiter <oberpapr@users.sourceforge.net>

RT Linux Update

run_auto.sh file for realtime/func/pthread_kill_latency/ testcase got missed out in first release of realtime tests. This patch adds run_auto.sh for testcase which is required to run this particular test through top-level run script, by, sudhanshu <sudh@linux.vnet.ibm.com>

msgctl10 & msgctl11 Test Cases Addition

Since msgmni now scales to the memory size, it may reach big values. To avoid forking 2*msgmni processes and create msgmni msg queues, take the min between the procfs value and MSGMNI (as found in linux/msg.h). Also integrated the following in libipc.a: . get_max_msgqueues(). get_used_msgqueues() Signed-off-by: Nadia Derbey <Nadia.Derbey@bull.net>

waitpid06 Fix

waitpid06.c uses a flag to detect whether something went wrong during the test. The issue is that this flag is not initialized, and I get random failure reports. Other tests might suffer from the same bug, but I did not observe it yet. The enclosed patch fixes this in a trivial way for waitpid06. Surprisingly, with my debian package I never got the error, but when I compiled myself, by, Louis Rilling <Louis.Rilling@kerlabs.com>

3rd Round of RT Linux Test Update

There are numerous cleanups, fixes and features went into our locally maintained version of realtime tests, since its Intergration in LTP december last year. This patch merges those changes into LTP tree. The patch majorly contains : - All features, cleanups and fixes done by IBM realtime team over last two month or so. - Change in copyrights( year, symbil and limiting columns to 80 chars) - Other few cleanups to ltp-realtime tests. Signed-off-by : Sudhanshu Singh<sudh@linux.vnet.ibm.com>

Waitpid07 Fix

waitpid07.c uses a flag to detect whether something went wrong during the test. The issue is that this flag is not initialized, and I get random failure reports, by, Louis Rilling <Louis.Rilling@kerlabs.com>

Waitpid Fix

waitpid tests: Fix failure detection flag initialization. On a similar pattern as waitpid06 and waitpid07, waitpid08-13 use a failure detection flag (called 'fail' instead of 'flag'). However except in waitpid09, this flag may be used uninitialized, which causes the test to randomly report failure. This patch ensures that the flag is reset at the beginning of each loop. Signed-off-by: Louis Rilling <Louis.Rilling@kerlabs.com>

Waitpid Fix

waitpid03/04: Fix condition numbers displayed when reporting errors. The condition numbers displayed while reporting errors in waitpid03 and waitpid04 are used initialized and are not consistently updated, which may lead to useless reports. Signed-off-by: Louis Rilling <Louis.Rilling@kerlabs.com>

Waitpid Fix

waitpid02-05: remove unused defines related to failure handling. Signed-off-by: Louis Rilling <Louis.Rilling@kerlabs.com>

SENDFILE Updates

Many tests cannot be executed concurrently. I have a few patches to make it possible to execute some tests in parallel/concurrency, to check SMP safeness, by, Renaud Lottiaux <Renaud.Lottiaux@kerlabs.com>

REMAP_FILE_PAGES Updates

Fix NFS issues in tst_rmdir (directory non empty) due to an unmapped file, by, Renaud Lottiaux <Renaud.Lottiaux@kerlabs.com>

REMAP_FILE_PAGES Updates

Fix a concurrency issue due to the (false) sharing of file /dev/shm/cache. This patch just create a different file for each process and unlink the file before exiting, by, Renaud Lottiaux <Renaud.Lottiaux@kerlabs.com>

doio/rwtest fix

The variable dfOpts (in #324) is seting to NULL even if the df is not a symbolic link. (It has to be "-P" itself to get the output portable).And so the "df $dfOpts $dir" (line #326) command is not giving a result expected by the succeeding statements. I have tested this patch both in lvm and fdisk partitions and found its working fine, by, Sudeesh John <sudeeshjohn@in.ibm.com>

MEM03 Update

This patch -try- to cleanup the mem03 test and fix a concurrency problem. Mainly, the test creates and removes files in the current directory. Since the tst_tmpdir() function was not used, several instances of the test was creating and removing files from each others !, by, Renaud Lottiaux <Renaud.Lottiaux@kerlabs.com>

FILE_TEST.sh fix

MREMAP04 Update

Here is a patch fixing concurrency issue in mremap04. Just use a shm key returned from the getipckey() function instead of a fixed hardcoded value, by, Renaud Lottiaux <Renaud.Lottiaux@kerlabs.com>

KILL05 Update

Paranoia concurrency fix. I have not encounter any real issue, but it is probably safer to be sure each process is using a different segment.-> use tst_tmpdir, to make getipckey generating a different key for each running process, by, Renaud Lottiaux <Renaud.Lottiaux@kerlabs.com>

4th Round of RT Linux Update

1) The pi-tests don't use the librttest infrastructure and simply duplicate code. 2) The thread-clock test doesn't use the librttest infrastructure. 3) Adds missing headers to the following files, Signed-Off-By: Chirag <chirag@linux.vnet.ibm.com>, Acked-By: Dinakar Guniguntala <dino@in.ibm.com>,Acked-By: Sebastien Dugue <sebastien.dugue@bull.net>

SHMAT02 Fix

Fixes a concurrency issue in shmat02. The second IPC key used in this test was generated doing a ++ on the first key. By doing this, it makes possible to get a conflict with a key generated by another process. To fix this, I just do a new call to getipckey() and check if the key is different from the previously generated one, by, Renaud Lottiaux <Renaud.Lottiaux@kerlabs.com>

Addition of CPU CONTROLLER TEST CASES to LTP

RT Linux Fix

This patch fixes the testcases mismerge due to the patch "There are numerous cleanup fixes and features went into our ..." from Sudhanshu Singh. Turned out there was less damage than I thought. Hopefully, it should restore the fixes and cleanups which were reverted before the February Release.
