Bug 1640067

Description of problem:
I'm attempting to get debug reports from abrt itself.

This triggers an selinux warning.

abrt-analyze-c is currently crashing with a segfault repeatedly.  I'm attempting to get a report from this to report a bug in abrt itself.

It's doing this when Python segfaults (c segfault, not python backtrace), which I can trigger reliably by running gnome-music (bz # 1635152)

Basically Python segfault:
Oct 17 11:50:21 sieve-deschouwer-co-za abrt-hook-ccpp[32427]: Process 32382 (python3.7) of user 1000 killed by SIGSEGV - dumping core
Oct 17 11:50:22 sieve-deschouwer-co-za abrt-hook-ccpp[32428]: Can't generate core backtrace: dwfl_getthread_frames failed: No DWARF information found
Oct 17 11:50:22 sieve-deschouwer-co-za abrt-hook-ccpp[32427]: Core backtrace generator exited with error 1

triggers abrt segfault:

SELinux is preventing abrt-hook-ccpp from using the 'sys_resource' capabilities.

*****  Plugin sys_resource (91.4 confidence) suggests   **********************

If you do not want processes to require capabilities to use up all the system resources on your system;
Then you need to diagnose why your system is running out of system resources and fix the problem.

According to /usr/include/linux/capability.h, sys_resource is required to:

/* Override resource limits. Set resource limits. */
/* Override quota limits. */
/* Override reserved space on ext2 filesystem */
/* Modify data journaling mode on ext3 filesystem (uses journaling
   resources) */
/* NOTE: ext2 honors fsuid when checking for resource overrides, so
   you can override using fsuid too */
/* Override size restrictions on IPC message queues */
/* Allow more than 64hz interrupts from the real-time clock */
/* Override max number of consoles on console allocation */
/* Override max number of keymaps */

Do
fix the cause of the SYS_RESOURCE on your system.

*****  Plugin catchall (9.59 confidence) suggests   **************************

If you believe that abrt-hook-ccpp should have the sys_resource capability by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'abrt-hook-ccpp' --raw | audit2allow -M my-abrthookccpp
# semodule -X 300 -i my-abrthookccpp.pp
