Subject: [PATCH] chcat: don't crash if access to binary policy is prohibited
Date: Sat, 9 May 2020 16:06:00 +0200	[thread overview]
Message-ID: <d204aaea-ca46-49c2-f7cd-6f20889cecbf@gmail.com> (raw)

sobject will crash if access to the binary policy is prohibited by
selinux, e.g. refpolicy
this also breaks file operations that don't require seobject.
