* ipv4: Pass flow key down into ip_append_*().David S. Miller2011-05-084-15/+19

* ipv4: Pass flow keys down into datagram packet building engine.David S. Miller2011-05-084-90/+86
| | | | | | | | | This way ip_output.c no longer needs rt->rt_{src,dst}. We already have these keys sitting, ready and waiting, on the stack or in a socket structure. Signed-off-by: David S. Miller <davem@davemloft.net>
* udp: Use flow key information instead of rt->rt_{src,dst}David S. Miller2011-05-081-6/+8
| | | | | | | | | | | | We have two cases. Either the socket is in TCP_ESTABLISHED state and connect() filled in the inet socket cork flow, or we looked up the route here and used an on-stack flow. Track which one it was, and use it to obtain src/dst addrs. Signed-off-by: David S. Miller <davem@davemloft.net>
* net: Allow ethtool to set interface in loopback mode.Mahesh Bandewar2011-05-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | This patch enables ethtool to set the loopback mode on a given interface. By configuring the interface in loopback mode in conjunction with a policy route / rule, a userland application can stress the egress / ingress path exposing the flows of the change in progress and potentially help developer(s) understand the impact of those changes without even sending a packet out on the network. Following set of commands illustrates one such example - a) ip -4 addr add 192.168.1.1/24 dev eth1 b) ip -4 rule add from all iif eth1 lookup 250 c) ip -4 route add local 0/0 dev lo proto kernel scope host table 250 d) arp -Ds 192.168.1.100 eth1 e) arp -Ds 192.168.1.200 eth1 f) sysctl -w net.ipv4.ip_nonlocal_bind=1 g) sysctl -w net.ipv4.conf.all.accept_local=1 # Assuming that the machine has 8 cores h) taskset 000f netserver -L 192.168.1.200 i) taskset 00f0 netperf -t TCP_CRR -L 192.168.1.100 -H 192.168.1.200 -l 30 Signed-off-by: Mahesh Bandewar <maheshb@google.com> Acked-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

| * batman-adv: Avoid deadlock between rtnl_lock and s_activeSven Eckelmann2011-05-081-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The hard_if_event is called by the notifier with rtnl_lock and tries to remove sysfs entries when a NETDEV_UNREGISTER event is received. This will automatically take the s_active lock. The s_active lock is also used when a new interface is added to a meshif through sysfs. In that situation we cannot wait for the rntl_lock before creating the actual batman-adv interface to prevent a deadlock. It is still possible to try to get the rtnl_lock and immediately abort the current operation when the trylock call failed. Signed-off-by: Sven Eckelmann <sven@narfation.org>
| * batman-adv: Remove unnecessary hardif_list_lockSven Eckelmann2011-05-084-24/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | hardif_list_lock is unneccessary because we already ensure that no multiple admin operations can take place through rtnl_lock. hardif_list_lock only adds additional overhead and complexity. Critical functions now check whether they are called with rtnl_lock using ASSERT_RTNL. It indirectly fixes the problem that orig_hash_del_if() expects that only one interface is deleted from hardif_list at a time, but hardif_remove_interfaces() removes all at once and then calls orig_hash_del_if().

| * batman-adv: multi vlan support for bridge loop detectionMarek Lindner2011-05-083-113/+298
| | | | | | | | | | | | | | | | | | | | | | The bridge loop detection for batman-adv allows the bat0 interface to be bridged into an ethernet segment which other batman-adv nodes are connected to. In order to also allow multiple VLANs on top of the bat0 interface to be bridged into the ethernet segment this patch extends the aforementioned bridge loop detection.

| | | | | | | | | | | | | | | | | | | | | | This allows us to acquire the exact route keying information from the protocol, however that might be managed.

* | ipv4: Use inet_csk_route_child_sock() in DCCP and TCP.David S. Miller2011-05-082-17/+20
| | | | | | | | | | | | | | Operation order is now transposed, we first create the child socket then we try to hook up the route. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | This is just like inet_csk_route_req() except that it operates after we've created the new child socket. In this way we can use the new socket's cork flow for proper route key storage. This will be used by DCCP and TCP child socket creation handling. Signed-off-by: David S. Miller <davem@davemloft.net>
* | sctp: Store a flowi in transports to provide persistent keying.David S. Miller2011-05-081-6/+3
| | | | | | | | | | | | | | | | | | Several future simplifications are possible now because of this. For example, the sctp_addr unions can simply refer directly to the flowi information. Signed-off-by: David S. Miller <davem@davemloft.net>
* | ipv4: Use cork flow in ip_queue_xmit()David S. Miller2011-05-081-2/+3
| | | | | | | | | | | | | | | | | | | | | | All invokers of ip_queue_xmit() must make certain that the socket is locked. All of SCTP, TCP, DCCP, and L2TP now make sure this is the case. Therefore we can use the cork flow during output route lookup in ip_queue_xmit() when the socket route check fails. Signed-off-by: David S. Miller <davem@davemloft.net>
* | ipv4: Use cork flow in inet_sk_{reselect_saddr,rebuild_header}()David S. Miller2011-05-081-5/+7
| | | | | | | | | | | | | | | | | | These two functions must be invoked only when the socket is locked (because socket identity modifications are made non-atomically). Therefore we can use the cork flow for output route lookups. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | l2tp_xmit_skb() must take the socket lock. It makes use of ip_queue_xmit() which expects to execute in a socket atomic context. Since we execute this function in software interrupts, we cannot use the usual lock_sock()/release_sock() sequence, instead we have to use bh_lock_sock() and see if a user has the socket locked, and if so drop the packet.

| | | | | | | | | | | | | | | | Both l2tp_ip_connect() and l2tp_ip_sendmsg() must take the socket lock. They both modify socket state non-atomically, and in particular l2tp_ip_sendmsg() increments socket private counters without using atomic operations. Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | ip_setup_cork() explicitly initializes every member of inet_cork except flags, addr, and opt.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we fast path datagram sends to avoid locking by putting the inet_cork on the stack we use up lots of space that isn't necessary. This is because inet_cork contains a "struct flowi" which isn't used in these code paths. Split inet_cork to two parts, "inet_cork" and "inet_cork_full". Only the latter of which has the "struct flowi" and is what is stored in inet_sock. Signed-off-by: David S. Miller <davem@davemloft.net> Acked-by: Eric Dumazet <eric.dumazet@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 4a94445c9a5c (net: Use ip_route_input_noref() in input path) added a bug in IP defragmentation handling, in case timeout is fired. When a frame is defragmented, we use last skb dst field when building final skb. Its dst is valid, since we are in rcu read section. But if a timeout occurs, we take first queued fragment to build one ICMP TIME EXCEEDED message. Problem is all queued skb have weak dst pointers, since we escaped RCU critical section after their queueing. icmp_send() might dereference a now freed (and possibly reused) part of memory. Calling skb_dst_drop() and ip_route_input_noref() to revalidate route is the only possible choice.

Currently, decision to skip the tailroom reservation in the tx path was taken only on whether driver wants MMIC to be generated in software or not. Following patch appends IV generation check for such decisions and fixes the following warning.

This patch tries to unify both by moving the special branch out of mac80211 rx hotpath and into into the software crypto part. This has the advantage that we can run a few more sanity checks on the data and verify if the key type was TKIP. This is very handy because several devices generate false postive MIC failure reports.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some circumstances hci_get_auth_req will return a value different from the current conn->auth_type. In these cases update conn->auth_type so that when a user confirm request comes it doesn't falsely trigger auto-accept.

Therefore, always send the mgmt_new_key event but add a store_hint parameter to it to indicate to user space whether the key should be stored or not.
