The Linux Test Project JULY 2008 Release Announcement

1) Log Message:
I've tried LTP and found some wrong mode at creating file/dir in LTP source files. Here is a patch. Junjiro Okajima<hooanon05@yahoo.co.jp>.

2) Log Message:
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). To fix this, we should instead expect our sleeps to last between 5 and 6 seconds, as in the patch inlined below. Signed-off-by: Craig Meier <crmeier@ghs.com>.

6) Log Message:
Fixes the following issues:
The LTP selinux-testsuite does not work out of the box on Red Hat Enterprise Linux 4. 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 global 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>.

7) Log Message:
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>.

However, there's one fix that works around a bug in uClibc's pthread implementation. 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>.

13) Log Message:
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>.

14)Log Message:
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.

15) Log Message:
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()).

17) Log Message:
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. In any case this would resolve a never-ending loop in aio01.c, where io_getevents() can be continuously called without having issued any actual request if io_submit() failed with -EAGAIN.

28) Log Message:
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 32-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. Gilles Carry <Gilles.Carry@bull.net>.

ltp/testcases/realtime/config.mk

29) Log Message:
First patch regroups TSC functions and macros definition into librttest. Second patch is to have an atomic reading of the 64-bit timebase register of powerpc64. This new function is only valid if -m64 is used when compiling the whole testcase suite with a powerpc64. Thirs patch is a fix to avoid spurious tsc_minus warning. These patches been tested on a ppc64 machine either with 32 or 64 bit binaries. (-m64). The same TSC read (rdtscll) macros and tsc_minus where implemented in three different tests. This patch put all this into librttest.*. Signed-off-by: Gilles Carry <gilles.carry@bull.net>. Cc: Tim Chavez <tinytim@us.ibm.com>. Acked-by: Darren Hart <dvhltc@us.ibm.com>.

30) Log Messsage:
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>.
