Description Doncho Gunchev 2019-03-19 10:55:56 UTC
Description of problem:
systemctl start watchdog
SELinux is preventing watchdog from 'write' accesses on the file

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

If you believe that watchdog should be allowed write access on the file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# ausearch -c 'watchdog' --raw | audit2allow -M my-watchdog
# semodule -X 300 -i my-watchdog.pp

Comment 1 Zdenek Pytela 2019-03-19 12:20:51 UTC

Thank you for reporting the issue. Can you find out where the file is located?

If it is /var/run/, the following command should be sufficient:

  # restorecon -Rv /var/run/

or running it recursively on /run which is the actual directory:

  # restorecon -Rvn /run

Comment 2 Zdenek Pytela 2019-03-28 17:28:45 UTC

Could you please help with locating the pid file and answer if giving it the correct label helped to resolve our issue?

Comment 3 Doncho Gunchev 2019-04-10 14:07:33 UTC
selinux-policy-3.14.2-53.fc29.noarch and kernel-5.0.6-200.fc29.x86_64 do not have this problem any more, 10x.
