| * | | | | | mac80211: do not calc frame duration when using HW rate-controlArik Nemtsov2011-02-031-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When rate-control is performed in HW, we cannot calculate frame duration as we do not have the skb transmission rate in SW. ieee80211_tx_h_calculate_duration() should only be called when ieee80211_tx_h_rate_ctrl() has been called before to initialize data in skb->cb. This doesn't happen for drivers with HW rate-control. Fixes the following warning when operating in AP-mode in a driver with HW rate-control.

The mac80211 on the other hand reinitializes its sdata structure every time the interface type is changed, losing the PSM configuration. Hence, if the interface type is changed to, say, ad-hoc and then back to managed, "iw wlan0 get power_save" will claim that PSM is enabled, when in fact on mac80211 level it is not. Fix this in cfg80211 by configuring the PSM state to the driver each time the interface is brought up instead of just when the interface is created.

Digging in it turns out this dates back to the last great sysctl reorg done where Al Viro introduced the requirement that sysctl directories needed to be created before and destroyed after the files in them. It turns out that in that great reorg /proc/sys/net/ipv6/neigh was overlooked. So this patch fixes that oversight and makes an annoying warning message go away. >------------[ cut here ]------------ >WARNING: at kernel/sysctl.c:1992 unregister_sysctl_table+0x134/0x164() >Pid: 23951, comm: kworker/u:3 Not tainted 2.6.37-350888.2010AroraKernelBeta.fc14.x86_64 #1 >Call Trace: > [<ffffffff8103e034>] warn_slowpath_common+0x80/0x98 > [<ffffffff8103e061>] warn_slowpath_null+0x15/0x17 > [<ffffffff810452f8>] unregister_sysctl_table+0x134/0x164 > [<ffffffff810e7834>] ? kfree+0xc4/0xd1 > [<ffffffff813439b2>] neigh_sysctl_unregister+0x22/0x3a > [<ffffffffa02cd14e>] addrconf_ifdown+0x33f/0x37b [ipv6] > [<ffffffff81331ec2>] ? skb_dequeue+0x5f/0x6b > [<ffffffffa02ce4a5>] addrconf_notify+0x69b/0x75c [ipv6] > [<ffffffffa02eb953>] ? ip6mr_device_event+0x98/0xa9 [ipv6] > [<ffffffff813d2413>] notifier_call_chain+0x32/0x5e > [<ffffffff8105bdea>] raw_notifier_call_chain+0xf/0x11 > [<ffffffff8133cdac>] call_netdevice_notifiers+0x45/0x4a > [<ffffffff8133d2b0>] rollback_registered_many+0x118/0x201 > [<ffffffff8133d3af>] unregister_netdevice_many+0x16/0x6d > [<ffffffff8133d571>] default_device_exit_batch+0xa4/0xb8 > [<ffffffff81337c42>] ? cleanup_net+0x0/0x194 > [<ffffffff81337a2a>] ops_exit_list+0x4e/0x56 > [<ffffffff81337d36>] cleanup_net+0xf4/0x194 > [<ffffffff81053318>] process_one_work+0x187/0x280 > [<ffffffff8105441b>] worker_thread+0xff/0x19f > [<ffffffff8105431c>] ? worker_thread+0x0/0x19f > [<ffffffff8105776d>] kthread+0x7d/0x85 > [<ffffffff81003824>] kernel_thread_helper+0x4/0x10 > [<ffffffff810576f0>] ? kthread+0x0/0x85 > [<ffffffff81003820>] ? kernel_thread_helper+0x0/0x10 >---[ end trace 8a7e9310b35e9486 ]--- Signed-off-by: Eric W.

This can happen in a sndmsg call, and after d33e455337ea ("net: Abstract default MTU metric calculation behind an accessor.") this leads to a crash in ip_append_data() because the blackhole dst_ops have no default_mtu() method and so dst_mtu() calls a NULL pointer. Fix this by adding default_mtu() methods (that simply return 0, matching the old behavior) to the blackhole dst_ops. The IPv4 part of this patch fixes a crash that I saw when using an IPSEC VPN; the IPv6 part is untested because I don't have an IPv6 VPN, but it looks to be needed as well.

Nothing else happens in this execution, so the call to genlmsg_cancel is simply unnecessary in this case. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression data; @@ if (data == NULL) { ... * genlmsg_cancel(..., data); ... return ...; } // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: John W.

The core idea is: For every packet arrival: Calculate Qave if (Qave < minth) Queue the new packet else Select randomly a packet from the queue if (both packets from same flow) then Drop both the packets else if (Qave > maxth) Drop packet else Admit packet with proability p (same as RED) See also: Rong Pan, Balaji Prabhakar, Konstantinos Psounis, "CHOKe: a stateless active queue management scheme for approximating fair bandwidth allocation", Proceeding of INFOCOM'2000, March 2000.

The scheduler tree lock was left locked in the case of an incorrect divisor value. Simplest fix is to move test outside of lock which also solves problem of partial update.

The line number of the command plays this role and there's an attribute reserved in the header part of the message to be filled out with the error line number. In order not to modify the original message received from the userspace, we construct a new, complete netlink error message and modifies the attribute there, then send it. Netlink is notified not to send its ACK/error message. Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu Signed-off-by: Patrick McHardy <kaber@trash.net>
