[LTP] [PATCH V3 12/23] trace_shed: Adapt to glibc 2.24 removal of union wait type

[Khem Raj]

This is now needed since glibc commit
https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=b49ab5f4503f36dcbf43f821f817da66b2931fe6;hp=5f5682b9654101ccaf375c2814cbddbe6033a725

The thread return status is
either -1 or pointer to the table. So there is no point in passing it to
WEXITSTATUS() and priting the value

fixes below error

trace_sched.c:425:16: error: invalid operands to binary & (have
'thread_sched_t * {aka struct <anonymous> *}' and 'int')

SIGCLD is defined with SIGCHLD anyway

see

bits/signum.h:#define     SIGCLD          SIGCHLD /* Same as SIGCHLD(System V).  */

additionally these tests can now compile on systemd with
musl libc

[LTP] [PATCH V3 19/23] creat06: Include limits.h for PATH_MAX

[Khem Raj]

Glibc includes limits.h indirectly and this error goes hidden
but musl is less pardoning

Fixes errors like

creat06.c:81:23: error: ‘PATH_MAX’ undeclared here (not in a function)
 static char long_name[PATH_MAX+2];
                       ^~~~~~~~

This is needed especially for musl, for glibc _GNU_SOURCE
is added by libc-features.h automatically. which defines SA_ONESHOT

Fixes

pec_listener.c: In function ‘main’:
pec_listener.c:233:27: error: ‘SA_ONESHOT’ undeclared (first use in this function)
  sigint_action.sa_flags = SA_ONESHOT;

[Cyril Hrubis]

Hi!

> its not a generally available typedef

Are you sure that __s32 is the only one missing?

Since all the __sXX and __uXX types are defined in a file included in
/usr/include/asm-generic/types.h (int-ll64.h on x86_64) which is a part
of linux-headers package. This rather looks like something is wrong with
your kernel headers.

The enum __ptrace_request is used to describe the function prototype in
the ptrace() manual page so one can argue that it's part of the official
API.

If I remeber right, it's missing in musl libc and the code in question
fails to compile.

CCing glibc ML and also man-pages ML to see if the type is used in
manual page intentionally or not.

The enum __ptrace_request is used to describe the function prototype in
the ptrace() manual page so one can argue that it's part of the official
API.

If I remeber right, it's missing in musl libc and the code in question
fails to compile.

CCing glibc ML and also man-pages ML to see if the type is used in
manual page intentionally or not.

What is the reason to add #define _GNU_SOURCE to crash01 and to remove
it from crash02? That looks like unintended change to me.

The rest is obviously OK.

Hmm, shouldn't this rather be defined(__GLIBC__) ?

As far as I can tell __USE_GNU is enabled if _GNU_SOURCE is defined
while __GLIBC__ is defined in glibc unconditionally.

Hmm are you sure that this fixes race condition where the test is not
attached to the group while the signal is send?

I would say that the kernel should guarantee that once the echo returns
back to userspace the processes is attached. Anything else would be
terribly racy.

There is different race condition as well, and this one is between the
memcg_process setting up the signal handler and the stress test testing
the signal that may be the cause for a random failures as well.

The define was needed only for these SA_* symbols which are removed
so I removed the define as well.

[LTP] [PATCH V3 15/23] Add periodic output for long time test.

[Tudor Florea]

Hi
This patch was needed to avoid the timeout of the script used to parse
the redirected output of the test. That being said don't have any strong
arguments (pro or cons) of cleaning up or improving the patch.
To be pedantic, I think that a newline for every 10 minutes is a little
too seldom; maybe just adding a new line every 5 minute is acceptable.
I hope that helps,
  Tudor.

This causes everything to be linked with pthreads which is enough for my

I do not like this.

I guess the easiest solution would be to eliminate the need for the
mutex to be recursive.

Which may be possible if we turn the T_exitval into counters and use
atomic operations to increment them which should us free from guarding
T_exitval updates called from tst_print() which are called from all over
the place. Or we can get rid of T_mode keeping only the default VERBOSE
behavior, which should have the same efect...

Newline per five lines is OK as well. Having 12 lines of output is still
much better than having 60.

Looking at it again, the sig_t is BSD specific one and may not be
defined on older glibc.

So the safest bet would be to define it as:

void (*k_sa_handler)(int);
