Subject: [PATCH 5/7] selinux: Add rules for sysctl and /proc/net accesses
Date: Wed, 16 Aug 2023 08:00:36 +0200	[thread overview]
Message-ID: <20230816060038.870746-6-sbrivio@redhat.com> (raw)
In-Reply-To: <20230816060038.870746-1-sbrivio@redhat.com>

That's what we actually need to check networking-related sysctls,
to scan for bound ports, and to manipulate bits of network
configuration inside pasta's target namespaces.
