Description Mikhail 2021-03-05 06:59:46 UTC
Description of problem:
SELinux is preventing accounts-daemon from using the 'fowner' capabilities.

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

If you believe that accounts-daemon should have the fowner 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 'accounts-daemon' --raw | audit2allow -M my-accountsdaemon
# semodule -X 300 -i my-accountsdaemon.pp

Comment 1 Zdenek Pytela 2021-03-05 08:16:27 UTC
Mikhail,

Do you know when or how the avc is triggered? Do you happen to know which file was accessed? By default the other records are not audited.

Comment 2 Zdenek Pytela 2021-03-19 15:44:21 UTC
Mikhail,

There seems to be a problem with XFS and new kernels. Could you try an older kernel, preferably from 5.11 series?

All reported avc happens during boot.
