This three part patchset fixes bugs in synchronization between
rds_tcp_accept_one() and the rds-tcp send/recv path.
Patch 1 ensures that the lock_sock() is taken appropriately
and the RDS datagram reassembly state is reset to synchronize
with the receive path.
Patch 2 ensures that partially sent RDS datagrams will get
retransmitted after rds_tcp_accept_one() switches sockets.
Patch 3 fixes a race window which would prematurely re-enable
rds_send_xmit() before the rds_tcp_connection setup has been
completed in rds_tcp_accept_one().
Sowmini Varadhan (3):
RDS: TCP: Add/use rds_tcp_reset_callbacks to reset tcp socket safely
RDS: TCP: Retransmit half-sent datagrams when switching sockets in
rds_tcp_reset_callbacks
RDS: TCP: fix race windows in send-path quiescence by
rds_tcp_accept_one()
