2012-01-03Bluetooth: Keep chan->state and sk->sk_state in syncGustavo F. Padovan1-0/+2
Those vars need to be in sync, otherwise l2cap_core.c can get the wrong state. Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
2012-01-03Bluetooth: Don't use *_bh locks anymoreGustavo F. Padovan1-12/+12
Those locks are not shared between interrupt and process context anymore, so remove the part that disable interrupts. We are still safe because preemption is disabled. Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>

2012-01-03Bluetooth: Queue adv_work on system workqueueAndre Guedes1-2/+1
This patch queues hdev->adv_work on the system-wide workqueue instead of on hdev->workqueue. This way we keep only tx/rx works on hdev->workqueue.

2012-01-03Bluetooth: Fix adv_work delayAndre Guedes1-2/+1
This patch fixes the adv_work delay. It should be set to ADV_ CLEAR_TIMEOUT instead of (jiffies + ADV_CLEAR_TIMEOUT) since queue_delayed_work() receives the number of jiffies to wait before queueing. It also removes the unnecessary cancel_delayed_ work_sync() call in case LE scan has been disabled.

The get operation was not sending the message that was built to user-space. This patch also includes the appropriate handling for the return value of netlink_unicast().

2011-12-31netfilter: ctnetlink: fix timeout calculationXi Wang1-2/+2
The sanity check (timeout < 0) never works; the dividend is unsigned and so is the division, which should have been a signed division. long timeout = (ct->timeout.expires - jiffies) / HZ; if (timeout < 0) timeout = 0; This patch converts the time values to signed for the division.

2011-12-31netem: fix classful handlingEric Dumazet1-121/+81
Commit 10f6dfcfde (Revert "sch_netem: Remove classful functionality") reintroduced classful functionality to netem, but broke basic netem behavior : netem uses an t(ime)fifo queue, and store timestamps in skb->cb[] If qdisc is changed, time constraints are not respected and other qdisc can destroy skb->cb[] and block netem at dequeue time. Fix this by always using internal tfifo, and optionally attach a child qdisc to netem (or a tree of qdiscs) Example of use : DEV=eth3 tc qdisc del dev $DEV root tc qdisc add dev $DEV root handle 30: est 1sec 8sec netem delay 20ms 10ms tc qdisc add dev $DEV handle 40:0 parent 30:0 tbf \ burst 20480 limit 20480 mtu 1514 rate 32000bps qdisc netem 30: root refcnt 18 limit 1000 delay 20.0ms 10.0ms Sent 190792 bytes 413 pkt (dropped 0, overlimits 0 requeues 0) rate 18416bit 3pps backlog 0b 0p requeues 0 qdisc tbf 40: parent 30: rate 256000bit burst 20Kb/8 mpu 0b lat 0us Sent 190792 bytes 413 pkt (dropped 6, overlimits 10 requeues 0) backlog 0b 5p requeues 0 Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> CC: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.

2011-12-31IPv6: Avoid taking write lock for /proc/net/ipv6_routeJosh Hunt2-1/+21
During some debugging I needed to look into how /proc/net/ipv6_route operated and in my digging I found its calling fib6_clean_all() which uses "write_lock_bh(&table->tb6_lock)" before doing the walk of the table. I found this on 2.6.32, but reading the code I believe the same basic idea exists currently. Looking at the rtnetlink code they are only calling "read_lock_bh(&table->tb6_lock);" via fib6_dump_table(). While I realize reading from proc isn't the recommended way of fetching the ipv6 route table; taking a write lock seems unnecessary and would probably cause network performance issues. To verify this I loaded up the ipv6 route table and then ran iperf in 3 cases: * doing nothing * reading ipv6 route table via proc (while :; do cat /proc/net/ipv6_route > /dev/null; done) * reading ipv6 route table via rtnetlink (while :; do ip -6 route show table all > /dev/null; done) * Load the ipv6 route table up with: * for ((i = 0;i < 4000;i++)); do ip route add unreachable 2000::$i; done * iperf commands: * client: iperf -i 1 -V -c <ipv6 addr> * server: iperf -V -s * iperf results - 3 runs each (in Mbits/sec) * nothing: client: 927,927,927 server: 927,927,927 * proc: client: 179,97,96,113 server: 142,112,133 * iproute: client: 928,927,928 server: 927,927,927 lock_stat shows taking the write lock is causing the slowdown. Using this info I decided to write a version of fib6_clean_all() which replaces write_lock_bh(&table->tb6_lock) with read_lock_bh(&table->tb6_lock). With this new function I see the same results as with my rtnetlink iperf test. Signed-off-by: Josh Hunt <joshhunt00@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-12-31unix_diag: Fixup RQLEN extension reportPavel Emelyanov1-1/+12
While it's not too late fix the recently added RQLEN diag extension to report rqlen and wqlen in the same way as TCP does. I.e. for listening sockets the ack backlog length (which is the input queue length for socket) in rqlen and the max ack backlog length in wqlen, and what the CINQ/OUTQ ioctls do for established.

Commit be639ac6 ("NET: AX.25: Check ioctl arguments to avoid overflows further down the road") rejects very large arguments, but doesn't completely fix overflows on 64-bit systems. Consider the AX25_T2 case. int opt; ... if (opt < 1 || opt > ULONG_MAX / HZ) { res = -EINVAL; break; } ax25->t2 = opt * HZ; The 32-bit multiplication opt * HZ would overflow before being assigned to 64-bit ax25->t2.
