Description Matteo Croce 2019-10-04 16:29:43 UTC
Description of problem:
just start
SELinux is preventing modprobe from 'map' accesses on the file /usr/lib/modules/5.3.1-matteo/modules.dep.bin.

*****  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.

Do
setsebool -P domain_can_mmap_files 1

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

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