Subject: [B.A.T.M.A.N.] [PATCH 02/10] batctl: Handle failure during hash_iterator allocation
Date: Thu, 23 Nov 2017 15:04:36 +0100 [thread overview]
Message-ID: <20171123140444.17119-3-sven.eckelmann@openmesh.com> (raw)
In-Reply-To: <20171123140444.17119-1-sven.eckelmann@openmesh.com>
The iterator functions should not try to start the iteration when the
iterator could not be allocated.
