On a system where SELinux is enforced, how to selectively disable SELinux
on a few custom linux processes without impacting the rest?

SELinux is preventing mktemp from using the dac_read_search
capability.
by Robert Moskowitz
I keep getting these errors.
I got them back with F32 and Xfce, and now with F35 and Xfce.
Here is the full detail. 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
