2012-09-13net_sched: gred: actually perform idling in WRED modeDavid Ward1-11/+15
gred_dequeue() and gred_drop() do not seem to get called when the queue is empty, meaning that we never start idling while in WRED mode. And since qidlestart is not stored by gred_store_wred_set(), we would never stop idling while in WRED mode if we ever started. This messes up the average queue size calculation that influences packet marking/dropping behavior. Now, we start WRED mode idling as we are removing the last packet from the queue. Also we now actually stop WRED mode idling when we are enqueuing a packet.

2012-09-13net_sched: gred: fix qave reporting via netlinkDavid Ward1-1/+4
q->vars.qavg is a Wlog scaled value, but q->backlog is not. In order to pass q->vars.qavg as the backlog value, we need to un-scale it. Additionally, the qave value returned via netlink should not be Wlog scaled, so we need to un-scale the result of red_calc_qavg(). This caused artificially high values for "Average Queue" to be shown by 'tc -s -d qdisc', but did not affect the actual operation of GRED.

2012-09-13mISDN: Fix wrong usage of flush_work_sync while holding locksKarsten Keil7-11/+15
It is a bad idea to hold a spinlock and call flush_work_sync. Move the workqueue cleanup outside the spinlock and use cancel_work_sync, on closing the channel this seems to be the more correct function. Remove the never used and constant return value of mISDN_freebchannel. Signed-off-by: Karsten Keil <[email protected]> Cc: <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2012-09-08net: small bug on rxhash calculationChema Gonzalez1-5/+6
In the current rxhash calculation function, while the sorting of the ports/addrs is coherent (you get the same rxhash for packets sharing the same 4-tuple, in both directions), ports and addrs are sorted independently. This implies packets from a connection between the same addresses but crossed ports hash to the same rxhash. For example, traffic between A=S:l and B=L:s is hashed (in both directions) from {L, S, {s, l}}. The same rxhash is obtained for packets between C=S:s and D=L:l. This patch ensures that you either swap both addrs and ports, or you swap none. Traffic between A and B, and traffic between C and D, get their rxhash from different sources ({L, S, {l, s}} for A<->B, and {L, S, {s, l}} for C<->D) The patch is co-written with Eric Dumazet <[email protected]> Signed-off-by: Chema Gonzalez <[email protected]> Signed-off-by: Eric Dumazet <[email protected]> Signed-off-by: David S.

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless into for-davem John W. Linville says: ==================== Please pull these fixes intended for 3.6. There are more commits here than I would like -- I got a bit behind while I was stalking Steven Rostedt in San Diego last week... I'll slow it down after this! There are a couple of pulls here. One is from Johannes: "Please pull (according to the below information) to get a few fixes. * a fix to properly disconnect in the driver when authentication or association fails * a fix to prevent invalid information about mesh paths being reported to userspace * a memory leak fix in an nl80211 error path" The other comes via Gustavo: "A few updates for the 3.6 kernel. There are two btusb patches to add more supported devices through the new USB_VENDOR_AND_INTEFACE_INFO() macro and another one that add a new device id for a Sony Vaio laptop, one fix for a user-after-free and, finally, two patches from Vinicius to fix a issue in SMP pairing." Along with those... Arend van Spriel provides a fix for a use-after-free bug in brcmfmac. Daniel Drake avoids a hang by not trying to touch the libertas hardware duing suspend if it is already powered-down. Felix Fietkau provides a batch of ath9k fixes that adress some potential problems with power settings, as well as a fix to avoid a potential interrupt storm. Gertjan van Wingerde provides a register-width fix for rt2x00, and a rt2x00 fix to prevent incorrectly detecting the rfkill status. He also provides a device ID patch. Hante Meuleman gives us three brcmfmac fixes, one that properly initializes a command structure, one that fixes a race condition that could lose usb requests, and one that removes some log spam. Marc Kleine-Budde offers an rt2x00 fix for a voltage setting on some specific devices. Mohammed Shafi Shajakhan sent an ath9k fix to avoid a crash related to using timers that aren't allocated when 2 wire bluetooth coexistence hardware is in use. Sergei Poselenov changes rt2800usb to do some validity checking for received packets, avoiding crashes on an ARM Soc. Stone Piao gives us an mwifiex fix for an incorrectly set skb length value for a command buffer. All of these are localized to their specific drivers, and relatively small. The power-related patches from Felix are bigger than I would like, but I merged them in consideration of their isolation to ath9k and the sensitive nature of power settings in wireless devices. ==================== Signed-off-by: David S.

2012-09-05ibmveth: Fix alignment of rx queue bugSantiago Leon1-17/+9
This patch fixes a bug found by Nish Aravamudan (https://lkml.org/lkml/2012/5/15/220) where the driver is not following the spec (it is not aligning the rx buffer on a 16-byte boundary) and the hypervisor aborts the registration, making the device unusable. The fix follows BenH's recommendation (https://lkml.org/lkml/2012/7/20/461) to replace the kmalloc+map for a single call to dma_alloc_coherent() because that function always aligns to a 16-byte boundary. The stable trees will run into this bug whenever the rx buffer kmalloc call returns something not aligned on a 16-byte boundary.

Make sure we stop the generic timer only if 'btcoex->hw_timer_enabled' is true(only if its up and running) Fixes the following crash [68757.020454] BUG: unable to handle kernel NULL pointer dereference at 0000000c [68757.020916] IP: [<f9b055c3>] ath9k_hw_gen_timer_stop+0x13/0x80 [ath9k_hw] [68757.021251] *pde = 00000000 [68757.024384] EIP: 0060:[<f9b055c3>] EFLAGS: 00010082 CPU: 0 [68757.024384] EIP is at ath9k_hw_gen_timer_stop+0x13/0x80 [ath9k_hw] [68757.024384] EAX: d32d0000 EBX: d32d0000 ECX: 00000000 EDX: 00000000 [68757.024384] ESI: e67c24c0 EDI: 00000296 EBP: e137be2c ESP: e137be20 [68757.024384] DS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0068 [68757.024384] CR0: 8005003b CR2: 0000000c CR3: 00b99000 CR4: 000407d0 [68757.024384] DR0: 00000000 DR1: 00000000 DR2: 00000000 DR3: 00000000 [68757.024384] DR6: ffff0ff0 DR7: 00000400 [68757.024384] Process kworker/u:2 (pid: 8917, ti=e137a000 task=ea7a6860 task.ti=e137a000) [68757.024384] Stack: [68757.024384] c06c4676 d32d0000 e67c24c0 e137be38 f81c9590 e67c1ca0 e137be40 f81c95d9 [68757.024384] e137be64 f81cd1c5 00000246 00000002 d32d0000 e67c05e0 e67c1ca0 e67c05e0 [68757.024384] 00000000 e137beac f81cdfa0 e137be84 00000246 00000246 e67c1ca0 e67c1ca0 [68757.024384] Call Trace: [68757.024384] [<c06c4676>] ? _raw_spin_lock_irqsave+0x86/0xa0 [68757.024384] [<f81c9590>] ath9k_gen_timer_stop+0x10/0x40 [ath9k] [68757.024384] [<f81c95d9>] ath9k_btcoex_stop_gen_timer+0x19/0x20 [ath9k] [68757.024384] [<f81cd1c5>] ath9k_ps_restore+0x85/0x110 [ath9k] [68757.024384] [<f81cdfa0>] ath9k_config+0x220/0x520 [ath9k] [68757.024384] [<f81cd47d>] ? ath9k_flush+0x15d/0x1b0 [ath9k] [68757.024384] [<f85c7ca5>] ieee80211_hw_config+0x135/0x2c0 [mac80211] [68757.024384] [<f860e3c8>] ieee80211_dynamic_ps_enable_work+0x198/0x5f0 [mac80211] Cc: Rajkumar Manoharan <[email protected]> Cc: Bala Shanmugam <[email protected]> Signed-off-by: Mohammed Shafi Shajakhan <[email protected]> Signed-off-by: John W.

2012-09-05ath9k_hw: enable PA linearizationFelix Fietkau1-3/+0
This feature had been disabled in ath9k because the code to support it was incomplete, but now the code is in sync with the internal QCA codebase, so it's time to enable it. On many newer devices, the calibration is assumed to be done with PA linearization enabled. Tests with a particular AR933x device showed that the signal emitted at full power was highly distorted and unreliable with PA linearization disabled. With this patch, the signal becomes clear and stability is improved. Signed-off-by: Felix Fietkau <[email protected]> Signed-off-by: John W. Linville <[email protected]>
2012-09-05ath9k: fix PA linearization calibration related crashFelix Fietkau4-8/+7
Before PAPRD training can run, the card needs to have sent a packet for thermal calibration. Sending a dummy packet with the PAPRD training flag set causes a crash under some circumstance. Fix the code by replacing the dummy tx with a delay that waits for a real packet tx to have occurred. Signed-off-by: Felix Fietkau <[email protected]> Signed-off-by: John W.

2012-09-05ath9k_hw: do not enable the MIB interrupt in the interrupt mask registerFelix Fietkau1-3/+0
The interrupt is no longer handling it. While it shouldn't fire (wraparound is highly unlikely), the consequences would be fatal (interrupt storm). Disable the interrupt to prevent that from happening. Signed-off-by: Felix Fietkau <[email protected]> Signed-off-by: John W. Linville <[email protected]>
2012-09-05rt2x00: fix voltage setting for RT3572/RT3592Marc Kleine-Budde1-0/+1
According to the vendor driver v2.6.0.1, during the rf register init the SRAM voltage should be increased to 1.35V and after 1ms decreased back to 1.2V. This patch adds the field setting of LDO_CFG0_LDO_CORE_VLEVEL accordingly.

2012-09-05mwifiex: fix skb length issue when send a command to firmwareStone Piao1-1/+14
When we send a command to firmware, we assumed that cmd_size will be always less than or equal to the structure size of host_cmd_ds_command. However, this is no longer true after we added AP support. There are some AP commands that Custom IE TLVs are included in command buffer, hence the cmd_size gets enlarged by the TLV data. We need to increase the skb length for the extra data.
