Description of problem:
Same as https://bugzilla.redhat.com/show_bug.cgi?id=1941445: 

Upgraded from F33->F34, touch /.autorelabel, closed laptop lid, came back, opened it back up and got a ton new alerts (~28 before, now at ~114!).
SELinux is preventing grep from 'map' accesses on the file /usr/bin/grep.

*****  Plugin catchall_boolean (89.3 confidence) suggests   ******************

If you want to allow domain to can mmap files
Then you must tell SELinux about this by enabling the 'domain_can_mmap_files' boolean.

setsebool -P domain_can_mmap_files 1

*****  Plugin catchall (11.6 confidence) suggests   **************************

If you believe that grep should be allowed map access on the grep 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 'grep' --raw | audit2allow -M my-grep
# semodule -X 300 -i my-grep.pp
