H A Dtcp_minisocks.cdiff dd929c1b3df94a7236c637fe294f04653d07b0d5 Wed Apr 08 17:34:04 CDT 2015 Eric Dumazet <edumazet@google.com> tcp: do not rearm rsk_timer on FastOpen requests

FastOpen requests are not like other regular request sockets.

They do not yet use rsk_timer : tcp_fastopen_queue_check()
simply manually removes one expired request from fastopenq->rskq_rst
list.

Therefore, tcp_check_req() must not call mod_timer_pending(),
otherwise we crash because rsk_timer was not initialized.

Fixes: fa76ce7328b ("inet: get rid of central tcp/dccp listener timer")
