SELinux is preventing mktemp from using the dac_read_search capability.

[Robert Moskowitz <rgm@xxxxxxxxxxxxxxx>]

I keep getting these errors.

I got them back with F32 and Xfce, and now with F35 and Xfce.

I asked on the SElinux list, but no one seems to be home.

Here is the full detail; it looks like it may be logwatch causing the problem.  What do I do to fix this?

===============

SELinux is preventing mktemp from using the dac_read_search capability.

*****  Plugin dac_override (91.4 confidence) suggests **********************

If you want to help identify if domain needs this access or you have a file with the wrong permissions on your system
Then turn on full auditing to get path information about the offending file and generate the error again.
Do

Turn on full auditing
# auditctl -w /etc/shadow -p w
Try to recreate AVC. Then execute
# ausearch -m avc -ts recent
If you see PATH record check ownership/permissions on file, and fix it,
otherwise report as a bugzilla.

*****  Plugin catchall (9.59 confidence) suggests **************************

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