Description Mikhail 2016-09-01 15:54:01 UTC
Description of problem:
SELinux is preventing abrt-hook-ccpp from 'sys_ptrace' accesses on the cap_userns Unknown.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that abrt-hook-ccpp should be allowed sys_ptrace access on the Unknown cap_userns 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

Comment 5 Giovanni Campagna 2016-09-26 22:12:12 UTC
Description of problem:
SELinux is complaining that abrt cannot ptrace a process in an userns. I would expect abrt found a crashdump from a flatpak.
abrt should not try to extract traces from flatpaks (until we have fedora-provided flatpaks), but also SELinux should not complain when abrt does its job
