Subject: [PATCH 13/16] commit ad495d7b6cfcd1bc2eaf06c42699be0bb5d84234 [try #4]
Date: Wed, 25 Apr 2007 16:50:04 +0100 [thread overview]
Message-ID: <20070425155003.26581.31916.stgit@warthog.cambridge.redhat.com> (raw)
In-Reply-To: <20070425154854.26581.97692.stgit@warthog.cambridge.redhat.com>
[NETLINK]: Mirror UDP MSG_TRUNC semantics.
If the user passes MSG_TRUNC in via msg_flags, return
the full packet size not the truncated size.
Idea from Herbert Xu and Thomas Graf.
