Note(s) from the Maintainer:
I participated in OLS 2008. I was exited to meet lot of people from the
community and know their personal opinion about LTP. I patiently heard
improvements to be done in LTP and the course of actions we need to
take. I will shortly start those discussions on the mailing lists. I was
happy to hear that people were happy that the project is active and
kicking. The immediate challenge before us is to increase that pace and
make it more effective, which i hope we will be able to achieve over a
period of time.
Our web site also contains other information such as:
- A Linux test tools matrix
- Technical papers
- How To's on Linux testing
- Code coverage analysis tool.
We would encourage the community to post results to
[EMAIL PROTECTED],
patches, new tests, bugs or comments/questions to [EMAIL PROTECTED],

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.

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 <[EMAIL PROTECTED]>.

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

implementation. Allow the amount of memory to be used to be passed as a
command-line argument. Matt Fleming <[EMAIL PROTECTED]>.

implementation. Allow the number of pages to use for the test to be specified

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

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 <[EMAIL

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()).

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. Signed-off-by: Andrea Righi <[EMAIL PROTECTED]>.

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.

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

tsc_minus warning. These patches been tested on a ppc64 machine either with 32
