Description Leszek Matok 2021-06-17 18:58:00 UTC
Description of problem:
F33 update pulled selinux-policy-3.14.6-38.fc33.noarch (from selinux-policy-3.14.6-37.fc33.noarch)

After a reboot, two alerts came up for mdadm accessing (search, read) a "directory" of "dma_heap".
SELinux is preventing mdadm from 'search' accesses on the katalog dma_heap.

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

Aby mdadm powinno mieć domyślnie search dostęp do dma_heap directory.
Then proszę to zgłosić jako błąd.
Można utworzyć lokalny moduł polityki, aby umożliwić ten dostęp.
można tymczasowo zezwolić na ten dostęp wykonując polecenia:
# ausearch -c 'mdadm' --raw | audit2allow -M my-mdadm
# semodule -X 300 -i my-mdadm.pp
