Re: freeradius-3.2.8-1.el9 fails to start

O.K. I have checked the audit logs and there is nothing in there. But you are right, setting selinux to permissive allows the server to start.

Thus, I have disabled the dontaudit rules and checked the audit log again and then you can easily find the solution:

# semodule -DB
# ausearch -m avc | audit2allow
…
#============= radiusd_t ==============

#!!!! This avc has a dontaudit rule in the current policy
allow radiusd_t self:capability net_admin;

#!!!! This avc can be allowed using the boolean 'radius_use_jit'
allow radiusd_t self:process execmem;
…

The selinux policy seems already to be prepared for this issue.

Thus

# setsebool -P radius_use_jit=1
# getsebool radius_use_jit
radius_use_jit --> on
# systemctl start radiusd
# semodule -B

And now it starts even in enforcing mode.

Regards.
