Subject: [B.A.T.M.A.N.] [PATCHv2] batman-adv: fix tt_local_reset_flags() function
Date: Sun, 16 Oct 2011 18:53:37 +0200 [thread overview]
Message-ID: <1318784017-28150-1-git-send-email-ordex@autistici.org> (raw)
Currently the counter of tt_local_entry structures (tt_local_num) is incremented
each time the tt_local_reset_flags() is invoked causing the node to send wrong
TT_REPONSE packets containing a copy of non-initialised memory thus corrupting
other nodes global translation table and making higher level communication
impossible.
