Description Susi Lehtola 2018-12-02 10:56:10 UTC
Description of problem:
I upgraded from Fedora 28 to Fedora 29, and started experiencing a huge number of these warnings.
SELinux is preventing pmdalinux from using the 'ipc_owner' capabilities.

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

If you believe that pmdalinux should have the ipc_owner 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 'pmdalinux' --raw | audit2allow -M my-pmdalinux
# semodule -X 300 -i my-pmdalinux.pp

    Add ipc_owner capability to pcp_pmcd_t domain BZ(1655282)

Comment 3 Marcin Zajaczkowski 2019-01-06 23:07:28 UTC
I observe it also in pcp-4.3.0-2.fc29.x86_64 - the latest version available in koji. @Lukas Do you plan to release the new version anytime soon?

I wanted to apply the change locally, but I can't find this commit in https://src.fedoraproject.org/cgit/rpms/pcp.git/ and https://github.com/performancecopilot/pcp .

Comment 4 Jon Heron 2019-01-08 01:19:32 UTC
Confirmed here too.
Upgrade from 28 to 29_64 now results in nonstop selinux AVC denial warnings.
