2013-01-03mac80211: use del_timer_sync for final sta cleanup timer deletionJohannes Berg
This is a very old bug, but there's nothing that prevents the timer from running while the module is being removed when we only do del_timer() instead of del_timer_sync(). The timer should normally not be running at this point, but it's not clearly impossible (or we could just remove this.)

2013-01-03mac80211: fix station destruction in AP/mesh modesJohannes Berg
Unfortunately, commit b22cfcfcae5b, intended to speed up roaming by avoiding the synchronize_rcu() broke AP/mesh modes as it moved some code into that work item that will still call into the driver at a time where it's no longer expected to handle this: after the AP or mesh has been stopped. To fix this problem remove the per-station work struct, maintain a station cleanup list instead and flush this list when stations are flushed. To keep this patch smaller for stable, do this when the stations are flushed (sta_info_flush()). This unfortunately brings back the original roaming delay; I'll fix that again in a separate patch. Also, Ben reported that the original commit could sometimes (with many interfaces) cause long delays when an interface is set down, due to blocking on flush_workqueue(). Since we now maintain the cleanup list, this particular change of the original patch can be reverted.

Do not scan on no-IBSS and disabled channels in IBSS mode. Doing this can trigger Microcode errors on iwlwifi and iwlegacy drivers.

Commit 63233159fd4e596568f5f168ecb0879b61631d47: bridge: Do not unregister all PF_BRIDGE rtnl operations introduced a bug where a removal of a single bridge from a multi-bridge system would remove MDB netlink handlers.

2013-01-03powerpc/vdso: Remove redundant locking in update_vsyscall_tz()Shan Hai
The locking in update_vsyscall_tz() is not only unnecessary because the vdso code copies the data unproteced in __kernel_gettimeofday() but also introduces a hard to reproduce race condition between update_vsyscall() and update_vsyscall_tz(), which causes user space process to loop forever in vdso code. The following patch removes the locking from update_vsyscall_tz(). Locking is not only unnecessary because the vdso code copies the data unprotected in __kernel_gettimeofday() but also erroneous because updating the tb_update_count is not atomic and introduces a hard to reproduce race condition between update_vsyscall() and update_vsyscall_tz(), which further causes user space process to loop forever in vdso code. The below scenario describes the race condition, x==0 Boot CPU other CPU proc_P: x==0 timer interrupt update_vsyscall x==1 x++;sync settimeofday update_vsyscall_tz x==2 x++;sync x==3 sync;x++ sync;x++ proc_P: x==3 (loops until x becomes even) Because the ++ operator would be implemented as three instructions and not atomic on powerpc.

2013-01-02leds: leds-gpio: set devm_gpio_request_one() flags param correctlyJavier Martinez Canillas
commit a99d76f leds: leds-gpio: use gpio_request_one changed the leds-gpio driver to use gpio_request_one() instead of gpio_request() + gpio_direction_output() Unfortunately, it also made a semantic change that breaks the leds-gpio driver. The gpio_request_one() flags parameter was set to: GPIOF_DIR_OUT | (led_dat->active_low ^ state) Since GPIOF_DIR_OUT is 0, the final flags value will just be the XOR'ed value of led_dat->active_low and state. This value were used to distinguish between HIGH/LOW output initial level and call gpio_direction_output() accordingly. With this new semantic gpio_request_one() will take the flags value of 1 as a configuration of input direction (GPIOF_DIR_IN) and will call gpio_direction_input() instead of gpio_direction_output(). int gpio_request_one(unsigned gpio, unsigned long flags, const char *label) { .. if (flags & GPIOF_DIR_IN) err = gpio_direction_input(gpio); else err = gpio_direction_output(gpio, (flags & GPIOF_INIT_HIGH) ? 1 : 0); .. } The right semantic is to evaluate led_dat->active_low ^ state and set the output initial level explicitly.

2013-01-02carl9170: fix -EINVAL bailout during init with !CONFIG_MAC80211_MESHChristian Lamparter
Sean reported that as of 3.7, his AR9170 device no longer works because the driver fails during initialization. He noted this is due to: "In carl9170/fw.c, ar->hw->wiphy is tagged with NL80211_IFTYPE_MESH_POINT support if the firmware has Content after Beacon Queuing. This is both in interface_modes and the only iface_combinations entry. If CONFIG_MAC80211_MESH is not set, ieee80211_register_hw removes NL80211_IFTYPE_MESH_POINT from interface_modes, but not iface_combinations. wiphy_register then checks to see if every interface type in every interface combination is in interface_modes. NL80211_IFTYPE_MESH_POINT was removed, so you get a WARN_ON warning and it returns -EINVAL, giving up." Unfortunately, the iface_combination (types) feature bitmap in ieee80211_iface_limit is part of a const member in the ieee80211_iface_combination struct. Hence, the MESH_POINT feature flag can't be masked by wiphy_register in the same way as interface_modes in ieee80211_register_hw.

2013-01-02rtlwifi: fix incorrect use of usb_alloc_coherent with usb_control_msgJussi Kivilinna
Incorrect use of usb_alloc_coherent memory as input buffer to usb_control_msg can cause problems in arch DMA code, for example kernel BUG at 'arch/arm/include/asm/dma-mapping.h:321' on ARM (linux-3.4). Change _usb_writeN_sync use kmalloc'd buffer instead.

2013-01-02ARM: OMAP2/3: PRM: fix bogus OMAP2xxx powerstate return valuesPaul Walmsley
On OMAP2xxx chips, the register bitfields for the PM_PWSTCTRL_*.POWERSTATE and PM_PWSTST_*.LASTSTATEENTERED are different than those used on OMAP3/4. The order is reversed. So, for example, on OMAP2xxx, 0x0 indicates 'ON'; but on OMAP3/4, 0x0 indicates 'OFF'. Similarly, on OMAP2xxx, 0x3 indicates 'OFF', but on OMAP3/4, 0x3 indicates 'ON'. To fix this, we treat the OMAP3/4 values as the powerdomain API values, and create new low-level powerdomain functions for the OMAP2xxx chips which translate between the OMAP2xxx values and the OMAP3/4 values. Without this patch, the conversion of the OMAP2xxx PM code to the functional powerstate code results in a non-booting kernel. Signed-off-by: Paul Walmsley <paul@pwsan.com>
2013-01-02ARM: OMAP3: clock data: Add missing enable/disable for EMU clockJon Hunter
The ETM/ETB drivers for OMAP3, enable the emu_src_ck clock in order to access the ETM/ETB hardware. The emu_src_ck should enable the EMU clock domain so that the ETM/ETB hardware is accessible. However, currently when enabling the emu_src_ck the EMU clock domain is not being enabled and so the ETM/ETB drivers are failing. Add enable/disable clock functions to enable the EMU clock domain when enabling the emu_src_ck. Signed-off-by: Jon Hunter <jon-hunter@ti.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>
