2013-03-20l2tp: purge session reorder queue on deleteTom Parkin1-0/+4
Add calls to l2tp_session_queue_purge as a part of l2tp_tunnel_closeall and l2tp_session_delete. Pseudowire implementations which are deleted only via. l2tp_core l2tp_session_delete calls can dispense with their own code for flushing the reorder queue.

2013-03-20l2tp: add session reorder queue purge function to coreTom Parkin2-0/+18
If an l2tp session is deleted, it is necessary to delete skbs in-flight on the session's reorder queue before taking it down. Rather than having each pseudowire implementation reaching into the l2tp_session struct to handle this itself, provide a function in l2tp_core to purge the session queue.

2013-03-20l2tp: close sessions before initiating tunnel deleteTom Parkin1-0/+1
When a user deletes a tunnel using netlink, all the sessions in the tunnel should also be deleted. Since running sessions will pin the tunnel socket with the references they hold, have the l2tp_tunnel_delete close all sessions in a tunnel before finally closing the tunnel socket.

2013-03-20l2tp: add udp encap socket destroy handlerTom Parkin1-0/+14
L2TP sessions hold a reference to the tunnel socket to prevent it going away while sessions are still active. However, since tunnel destruction is handled by the sock sk_destruct callback there is a catch-22: a tunnel with sessions cannot be deleted since each session holds a reference to the tunnel socket. If userspace closes a managed tunnel socket, or dies, the tunnel will persist and it will be neccessary to individually delete the sessions using netlink commands. This is ugly. To prevent this occuring, this patch leverages the udp encapsulation socket destroy callback to gain early notification when the tunnel socket is closed. This allows us to safely close the sessions running in the tunnel, dropping the tunnel socket references in the process. The tunnel socket is then destroyed as normal, and the tunnel resources deallocated in sk_destruct. While we're at it, ensure that l2tp_tunnel_closeall correctly drops session references to allow the sessions to be deleted rather than leaking.

2013-03-20udp: add encap_destroy callbackTom Parkin3-0/+16
Users of udp encapsulation currently have an encap_rcv callback which they can use to hook into the udp receive path. In situations where a encapsulation user allocates resources associated with a udp encap socket, it may be convenient to be able to also hook the proto .destroy operation. For example, if an encap user holds a reference to the udp socket, the destroy hook might be used to relinquish this reference. This patch adds a socket destroy hook into udp, which is set and enabled in the same way as the existing encap_rcv hook.

2013-03-19PCI: Use ROM images from firmware only if no other ROM source availableMatthew Garrett1-20/+35
Mantas Mikulėnas reported that his graphics hardware failed to initialise after commit f9a37be0f02a ("x86: Use PCI setup data"). The aim of this commit was to ensure that ROM images were available on some Apple systems that don't expose the GPU ROM via any other source. In this case, UEFI appears to have provided a broken ROM image that we were using even though there was a perfectly valid ROM available via other sources. The simplest way to handle this seems to be to just re-order pci_map_rom() and leave any firmare-supplied ROM to last.

2013-03-19packet: packet fanout rollover during socket overloadWillem de Bruijn7-24/+451
Changes: v3->v2: rebase (no other changes) passes selftest v2->v1: read f->num_members only once fix bug: test rollover mode + flag Minimize packet drop in a fanout group. If one socket is full, roll over packets to another from the group. Maintain flow affinity during normal load using an rxhash fanout policy, while dispersing unexpected traffic storms that hit a single cpu, such as spoofed-source DoS flows. Rollover breaks affinity for flows arriving at saturated sockets during those conditions. The patch adds a fanout policy ROLLOVER that rotates between sockets, filling each socket before moving to the next. It also adds a fanout flag ROLLOVER. If passed along with any other fanout policy, the primary policy is applied until the chosen socket is full. Then, rollover selects another socket, to delay packet drop until the entire system is saturated. Probing sockets is not free. Selecting the last used socket, as rollover does, is a greedy approach that maximizes chance of success, at the cost of extreme load imbalance. In practice, with sufficiently long queues to absorb bursts, sockets are drained in parallel and load balance looks uniform in `top`. To avoid contention, scales counters with number of sockets and accesses them lockfree. Values are bounds checked to ensure correctness. Tested using an application with 9 threads pinned to CPUs, one socket per thread and sufficient busywork per packet operation to limits each thread to handling 32 Kpps. When sent 500 Kpps single UDP stream packets, a FANOUT_CPU setup processes 32 Kpps in total without this patch, 270 Kpps with the patch. Tested with read() and with a packet ring (V1). Also, passes psock_fanout.c unit test added to selftests. Signed-off-by: Willem de Bruijn <willemb@google.com> Reviewed-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

because xfrm policy direction has same value with corresponding flow direction, so this problem is covered. In xfrm_lookup and __xfrm_policy_check, flow_cache_lookup is used to accelerate the lookup.

2013-03-19inet: limit length of fragment queue hash table bucket listsHannes Frederic Sowa5-16/+44
This patch introduces a constant limit of the fragment queue hash table bucket list lengths. Currently the limit 128 is choosen somewhat arbitrary and just ensures that we can fill up the fragment cache with empty packets up to the default ip_frag_high_thresh limits. It should just protect from list iteration eating considerable amounts of cpu. If we reach the maximum length in one hash bucket a warning is printed. This is implemented on the caller side of inet_frag_find to distinguish between the different users of inet_fragment.c. I dropped the out of memory warning in the ipv4 fragment lookup path, because we already get a warning by the slab allocator.

2013-03-19ipvs: add backup_only flag to avoid loopsJulian Anastasov4-4/+34
Dmitry Akindinov is reporting for a problem where SYNs are looping between the master and backup server when the backup server is used as real server in DR mode and has IPVS rules to function as director. Even when the backup function is enabled we continue to forward traffic and schedule new connections when the current master is using the backup server as real server. While this is not a problem for NAT, for DR and TUN method the backup server can not determine if a request comes from client or from director. To avoid such loops add new sysctl flag backup_only. It can be needed for DR/TUN setups that do not need backup and director function at the same time. When the backup function is enabled we stop any forwarding and pass the traffic to the local stack (real server mode). The flag disables the director function when the backup function is enabled. For setups that enable backup function for some virtual services and director function for other virtual services there should be another more complex solution to support DR/TUN mode, may be to assign per-virtual service syncid value, so that we can differentiate the requests.
