Description Doncho Gunchev 2018-12-10 06:27:10 UTC
Description of problem:
systemctl start ras-mc-ctl.service
SELinux is preventing ras-mc-ctl from 'execute' accesses on the file /usr/bin/perl.

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

If you believe that ras-mc-ctl should be allowed execute access on the perl 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 'ras-mc-ctl' --raw | audit2allow -M my-rasmcctl
# semodule -X 300 -i my-rasmcctl.pp

    Allow rasdaemon_t domain to execute binaries labeled as bin_t BZ(1657622)

Comment 2 Thomas Neuber 2018-12-14 20:27:43 UTC
Description of problem:
install package rasdaemon (0.6.2-3.fc29.x86_64)
start ras-mc-ctl.service using systemctl start ras-mc-ctl.service --> fails - SELinux prevents map file /usr/bin/perl

SE troubleshooter suggested: setsebool -P domain_can_mmap_files 1

after applying this command and another try to start the service  --> fails - SELinux prevents execute file /usr/bin/perl
