Subject: [PATCH net-next 21/23] rxrpc: Allow security classes to give more info on server keys
Date: Thu, 01 Oct 2020 15:59:10 +0100	[thread overview]
Message-ID: <160156435039.1728886.16686648974772019017.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <160156420377.1728886.5309670328610130816.stgit@warthog.procyon.org.uk>

Allow a security class to give more information on an rxrpc_s-type key when
it is viewed in /proc/keys.  This will allow the upcoming RxGK security
class to show the enctype name here.
