2016-06-07net: sched: fix tc_should_offload for specific clsact classesDaniel Borkmann
When offloading classifiers such as u32 or flower to hardware, and the qdisc is clsact (TC_H_CLSACT), then we need to differentiate its classes, since not all of them handle ingress, therefore we must leave those in software path. Add a .tcf_cl_offload() callback, so we can generically handle them, tested on ixgbe. Fixes: 10cbc6843446 ("net/sched: cls_flower: Hardware offloaded filters statistics support") Fixes: 5b33f48842fa ("net/flower: Introduce hardware offload support") Fixes: a1b7c5fd7fe9 ("net: sched: add cls_u32 offload hooks for netdevs") Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: John Fastabend <john.r.fastabend@intel.com> Signed-off-by: David S.

The police action is using its own code to initialize tcf hash info, which makes us to forgot to initialize a->hinfo correctly. Fix this by calling the helper function tcf_hash_create() directly.

Patch 2 ensures that partially sent RDS datagrams will get retransmitted after rds_tcp_accept_one() switches sockets.

2016-06-07RDS: TCP: fix race windows in send-path quiescence by rds_tcp_accept_one()Sowmini Varadhan
The send path needs to be quiesced before resetting callbacks from rds_tcp_accept_one(), and commit eb192840266f ("RDS:TCP: Synchronize rds_tcp_accept_one with rds_send_xmit when resetting t_sock") achieves this using the c_state and RDS_IN_XMIT bit following the pattern used by rds_conn_shutdown(). However this leaves the possibility of a race window as shown in the sequence below take t_conn_lock in rds_tcp_conn_connect send outgoing syn to peer drop t_conn_lock in rds_tcp_conn_connect incoming from peer triggers rds_tcp_accept_one, conn is marked CONNECTING wait for RDS_IN_XMIT to quiesce any rds_send_xmit threads call rds_tcp_reset_callbacks [.. race-window where incoming syn-ack can cause the conn to be marked UP from rds_tcp_state_change ..] lock_sock called from rds_tcp_reset_callbacks, and we set t_sock to null As soon as the conn is marked UP in the race-window above, rds_send_xmit() threads will proceed to rds_tcp_xmit and may encounter a null-pointer deref on the t_sock. Given that rds_tcp_state_change() is invoked in softirq context, whereas rds_tcp_reset_callbacks() is in workq context, and testing for RDS_IN_XMIT after lock_sock could result in a deadlock with tcp_sendmsg, this commit fixes the race by using a new c_state, RDS_TCP_RESETTING, which will prevent a transition to RDS_CONN_UP from rds_tcp_state_change().

2016-06-07RDS: TCP: Add/use rds_tcp_reset_callbacks to reset tcp socket safelySowmini Varadhan
When rds_tcp_accept_one() has to replace the existing tcp socket with a newer tcp socket (duelling-syn resolution), it must lock_sock() to suppress the rds_tcp_data_recv() path while callbacks are being changed. Also, existing RDS datagram reassembly state must be reset, so that the next datagram on the new socket does not have corrupted state. Similarly when resetting the newly accepted socket, appropriate locks and synchronization is needed. This commit ensures correct synchronization by invoking kernel_sock_shutdown to reset a newly accepted sock, and by taking appropriate lock_sock()s (for old and new sockets) when resetting existing callbacks.
