SELinux user map order:
unconfined_u:s0-s0:c0.c1023$xguest_u:s5-s1:c0-c4.c3.c8,c4:→Why is stuff
Default SELinux user: unconfined_u:s0-s0:c0.c1023
PAC type: MS-PAC
Obviously extra info should not be allowed.
Is "s5-s1" or "c4.c3" valid? Can the first value be higher than the second?
AFAIK (I'm not an expert though), MCS doesn't allow dashes, so "c0-c4"
should not be allowed. Chains like "c1.c2.c3" also don't look right.
... Also, the MLS/MCS numeric limits are not enforced correctly:
Right. We can create a ticket to harden the validation if we want. So far, the
purpose of this ticket/patch is to make validation of config values consistent
with selinuxusermap plugin. I will let Rob to chime in, but I would keep this
patch as is.
Yes, please open another ticket for the validation issues.
