Description Jakub Filak 2016-11-03 06:54:50 UTC
Description of problem:
/usr/sbin/abrt-server has gained the capability to read process details of the process that is reporting an error and SELinux prevents abrt-server to access the /proc/[pid]/ns/ipc file which is used in two ways:

1. its value is compared to /proc/1/ns/ipc to detect own IPC namespace
https://github.com/abrt/abrt/commit/da53089e02cd11fc3a097df6bdf29bc17f0a6e78#diff-fe69ce5f2310380460e8cdc03c2df2d7R669

2. its value is compared to all processes in the reporting process' parent hierarchy to identify the command that created the namespace
https://github.com/abrt/abrt/commit/da53089e02cd11fc3a097df6bdf29bc17f0a6e78#diff-fe69ce5f2310380460e8cdc03c2df2d7R690

Version-Release number of selected component (if applicable):
selinux-policy-3.13.1-221.fc26.noarch

Steps to Reproduce:
1. install ABRT from the current upstream master
2. induce an uncaught Python exception (will_python_raise from the will-crash package)
