Subject: [PATCH] mcstrans: start early and stop late
Date: Wed, 11 Dec 2019 14:32:01 +0100 [thread overview]
Message-ID: <20191211133201.2353261-1-dac.override@gmail.com> (raw)
It stopped too early, exposing a bug in sudo selinux_restore_tty():
SELINUX_ERR op=setxattr invalid_context="wheel.id:wheel.role:users.terminals.pty.pty_file:SystemLow"
avc: denied { mac_admin } for pid=859 comm="sudo" capability=33 scontext=wheel.id:wheel.role:sudo.wheel.subj:s0 tcontext=wheel.id:wheel.role:sudo.wheel.subj:s0 tclass=capability2 permissive=0
If we want to be able to reference human readable contexts in SELinuxContext= and nspawn -Z and -L then we need mcstrans ASAP
