Subject: [PATCH 1/1] grant permission to map security_t
Date: Tue, 2 Jul 2019 15:31:58 +0000 [thread overview]
Message-ID: <20190702153128.14244-1-dsugar@tresys.com> (raw)
I'm seeing the following denial while installing RPMs.
type=AVC msg=audit(1560944462.698:217): avc: denied { map } for pid=1265 comm="rpm" path="/sys/fs/selinux/status" dev="selinuxfs" ino=19 scontext=system_u:system_r:rpm_t:s0 tcontext=system_u:object_r:security_t:s0 tclass=file permissive=1
The RedHat targeted policy has the change in this patch. I'm not sure if this is preferred, or
if it would be better to create a new interface 'selinux_map_security_files' (or similar).
