2012-09-19ipv6: unify conntrack reassembly expire code with standard oneAmerigo Wang2-99/+38
Two years ago, Shan Wei tried to fix this: http://patchwork.ozlabs.org/patch/43905/ The problem is that RFC2460 requires an ICMP Time Exceeded -- Fragment Reassembly Time Exceeded message should be sent to the source of that fragment, if the defragmentation times out. " If insufficient fragments are received to complete reassembly of a packet within 60 seconds of the reception of the first-arriving fragment of that packet, reassembly of that packet must be abandoned and all the fragments that have been received for that packet must be discarded. If the first fragment (i.e., the one with a Fragment Offset of zero) has been received, an ICMP Time Exceeded -- Fragment Reassembly Time Exceeded message should be sent to the source of that fragment. " As Herbert suggested, we could actually use the standard IPv6 reassembly code which follows RFC2460. With this patch applied, I can see ICMP Time Exceeded sent from the receiver when the sender sent out 3/4 fragmented IPv6 UDP packet.

2012-09-19pkt_sched: fix virtual-start-time update in QFQPaolo Valente1-1/+4
If the old timestamps of a class, say cl, are stale when the class becomes active, then QFQ may assign to cl a much higher start time than the maximum value allowed. This may happen when QFQ assigns to the start time of cl the finish time of a group whose classes are characterized by a higher value of the ratio max_class_pkt/weight_of_the_class with respect to that of cl. Inserting a class with a too high start time into the bucket list corrupts the data structure and may eventually lead to crashes. This patch limits the maximum start time assigned to a class.

2012-09-19tcp: flush DMA queue before sk_wait_data if rcv_wnd is zeroMichal Kubeček1-2/+8
If recv() syscall is called for a TCP socket so that - IOAT DMA is used - MSG_WAITALL flag is used - requested length is bigger than sk_rcvbuf - enough data has already arrived to bring rcv_wnd to zero then when tcp_recvmsg() gets to calling sk_wait_data(), receive window can be still zero while sk_async_wait_queue exhausts enough space to keep it zero. As this queue isn't cleaned until the tcp_service_net_dma() call, sk_wait_data() cannot receive any data and blocks forever. If zero receive window and non-empty sk_async_wait_queue is detected before calling sk_wait_data(), process the queue first. Signed-off-by: Michal Kubecek <[email protected]> Signed-off-by: David S.

2012-09-18cfg80211: fix possible circular lock on reg_regdb_search()Luis R. Rodriguez1-3/+9
When call_crda() is called we kick off a witch hunt search for the same regulatory domain on our internal regulatory database and that work gets kicked off on a workqueue, this is done while the cfg80211_mutex is held. If that workqueue kicks off it will first lock reg_regdb_search_mutex and later cfg80211_mutex but to ensure two CPUs will not contend against cfg80211_mutex the right thing to do is to have the reg_regdb_search() wait until the cfg80211_mutex is let go.

2012-09-18net: rt_cache_flush() cleanupEric Dumazet1-17/+2
We dont use jhash anymore since route cache removal, so we can get rid of get_random_bytes() calls for rt_genid changes. Signed-off-by: Eric Dumazet <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2012-09-18ipv4/route: arg delay is useless in rt_cache_flush()Nicolas Dichtel6-34/+21
Since route cache deletion (89aef8921bfbac22f), delay is no more used. Remove it. Signed-off-by: Nicolas Dichtel <[email protected]> Acked-by: Eric Dumazet <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2012-09-18cfg80211/nl80211: Notify connection request failure in AP modePandiyarajan Pitchaimuthu3-0/+50
In AP mode, when a station requests connection to an AP and if the request is failed for particular reason, userspace is notified about the failure through NL80211_CMD_CONN_FAILED command. Reason for the failure is sent through the attribute NL80211_ATTR_CONN_FAILED_REASON. Signed-off-by: Pandiyarajan Pitchaimuthu <[email protected]> Signed-off-by: Johannes Berg <[email protected]>
2012-09-18wireless: remove unreachable codeAlan Cox1-19/+1
The only case where intersected_rd can become non NULL is within an if. All paths from that if return, so the end chunk has therefore squawked its last and is no more. Signed-off-by: Alan Cox <[email protected]> Signed-off-by: Johannes Berg <[email protected]>
2012-09-17userns: Convert the audit loginuid to be a kuidEric W. Biederman6-16/+16
Always store audit loginuids in type kuid_t. Print loginuids by converting them into uids in the appropriate user namespace, and then printing the resulting uid. Modify audit_get_loginuid to return a kuid_t. Modify audit_set_loginuid to take a kuid_t. Modify /proc/<pid>/loginuid on read to convert the loginuid into the user namespace of the opener of the file. Modify /proc/<pid>/loginud on write to convert the loginuid rom the user namespace of the opener of the file.

2012-09-179P: Fix race in p9_write_work()Simon Derr1-9/+10
See previous commit about p9_read_work() for details. This fixes a similar race between p9_write_work() and p9_poll_mux() Signed-off-by: Simon Derr <[email protected]> Signed-off-by: Eric Van Hensbergen <[email protected]>
2012-09-179P: fix test at the end of p9_write_work()Simon Derr1-1/+1
At the end of p9_write_work() we want to test if there is still data to send. This means: - either the current request still has data to send (wsize != 0) - or there are requests in the unsent queue Signed-off-by: Simon Derr <[email protected]> Signed-off-by: Eric Van Hensbergen <[email protected]>
2012-09-179P: Fix race in p9_read_work()Simon Derr1-7/+7
Race scenario between p9_read_work() and p9_poll_mux() Data arrive, Rworksched is set, p9_read_work() is called. thread A thread B p9_read_work() . reads data . checks if new data ready. No. . gets preempted . More data arrive, p9_poll_mux() is called. . . . p9_poll_mux() . . if (!test_and_set_bit(Rworksched, . &m->wsched)) { . schedule_work(&m->rq); . } . . -> does not schedule work because . Rworksched is set . . clear_bit(Rworksched, &m->wsched); return; No work has been scheduled, and yet data are waiting. Currently p9_read_work() checks if there is data to read, and if not, it clears Rworksched. I think it should clear Rworksched first, and then check if there is data to read.

2012-09-17llc2: Remove explicit indexing of state action arraysBen Hutchings1-4/+4
These arrays are accessed by iteration in llc_exec_station_trans_actions(). There must not be any zero-filled gaps in them, so the explicit indices are pointless. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2012-09-17llc2: Remove the station send queueBen Hutchings1-32/+2
We only ever put one skb on the send queue, and then immediately send it. Remove the queue and call dev_queue_xmit() directly. This leaves struct llc_station empty, so remove that as well. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
