Subject: BGP: Fixed corking of RX
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3685b0f9b6ada2d1e4efdcac3348785e466daf6e;p=thirdparty%2Fbird.git

BGP: Fixed corking of RX

If cork occurred after some incoming data had been already processed,
BGP incorrectly processed them again after uncorking because it forgot
to store the actual socket state.

Now storing the socket state (done at the end of bgp_rx()) and
therefore the bug is fixed.
