commit eae5783908042a762c24e1bd11876edb91d314b1 upstream.
This patch fixes the problems below:
1. In non-shutdown_ack_sent states: in sctp_sf_do_5_1B_init() and
sctp_sf_do_5_2_2_dupinit():
chunk length check should be done before any checks that may cause
to send abort, as making packet for abort will access the init_tag
from init_hdr in sctp_ootb_pkt_new().
2. In shutdown_ack_sent state: in sctp_sf_do_9_2_reshutack():
The same checks as does in sctp_sf_do_5_2_2_dupinit() is needed
for sctp_sf_do_9_2_reshutack().
