Subject: [PATCH v3] Allow systemd to getattr all files
Date: Thu, 23 Jan 2020 12:40:49 +0000
Message-ID: <> (raw)

Systemd has ConditionPath.*, ConditionFile.* and ConditionDir* which
are used to check various path/file/directory to control starting a
service.  But this requires getattr permissions on the types.
Example denials that fit the problem.

The first example is from lvm where accessing config file.

type=AVC msg=audit(1575427946.229:1624): avc:  denied  { getattr } for
pid=1 comm="systemd" path="/etc/lvm/lvm.conf" dev="dm-0" ino=51799
tcontext=system_u:object_r:lvm_etc_t:s0 tclass=file permissive=0

This second example is from chronyd, but it is happening becuase I added
the conditional in a drop-in file. 

type=AVC msg=audit(1575427959.882:1901): avc:  denied  { getattr } for
pid=1 comm="systemd" path="/etc/chrony.conf" dev="dm-0" ino=53824
tcontext=system_u:object_r:chronyd_conf_t:s0 tclass=file permissive=1

v3 - rework to not use interface and allow getattr for all files
