2012-05-14rtlwifi: fix for race condition when firmware is cachedLarry Finger
In commit b0302ab, the rtlwifi family of drivers was converted to use asynchronous firmware loading. Unfortumately, the implementation was racy, and the ieee80211 routines could be started before rtl_init_core() was called to setup the data. This patch fixes the bug noted in https://bugzilla.kernel.org/show_bug.cgi?id=43187.

2012-05-03iwlwifi: fix skb truesize underestimationEric Dumazet
By default, iwlwifi uses order-1 pages (8 KB) to store incoming frames, but doesnt say so in skb->truesize. This makes very possible to exhaust kernel memory since these skb evade normal socket memory accounting. As struct ieee80211_hdr is going to be pulled before calling IP stack, there is no need to use dev_alloc_skb() to reserve NET_SKB_PAD bytes. alloc_skb() is ok in this driver, allowing more tailroom. Pull beginning of frame in skb header, in the hope we can reuse order-1 pages in the driver immediately for small frames and reduce their truesize to the minimum (linear skbs) Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Cc: Wey-Yi Guy <wey-yi.w.guy@intel.com> Cc: "John W.

2012-05-02Revert "ath9k_hw: Fix incorrect spur_freq_sd for AR9003"Rajkumar Manoharan
This reverts commit a844adfd7bee4edc66d337de6c33b348e83552a8. The commit a844adfd is degrading rx sensitivity of lower rate in HT40 mode and it is confirmed that reverting the change is improving rx sensitivity. spur_freq_sd (for self-corr in AGC) is defined with respect to the center of each 20MHz channel while spur_phase_delta (for self-corr in Rx and spur data filter) is defined with respect to the center of current RF channel. So in short, we need to subtract spur_freq_sd (for self-corr in AGC) by the offset between the center of primary20 and the center of RF channel in SW. This offset could be +/10 MHz for dynamic 40.

2012-04-27wl1251: fix crash on remove due to premature kfreeGrazvydas Ignotas
Currently SDIO glue frees it's own structure before calling wl1251_free_hw(), which in turn calls ieee80211_unregister_hw(). The later call may result in a need to communicate with the chip to stop it (as it happens now if the interface is still up before rmmod), which means calls are made back to the glue, resulting in freed memory access. Fix this by freeing glue data last. Cc: stable@vger.kernel.org # v2.6.37+ Signed-off-by: Grazvydas Ignotas <notasas@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

Commit 2a19032 (b43: reload phy and bss settings after core restarts) introduced an unconditional call to b43_op_config() at the end of b43_op_start(). When firmware fails to load this can wedge the system. There's no need to reload the configuration after a failed initialization anyway, so only make the call if initialization was successful.

2012-04-24iwlwifi: fix hardware queue programmingJohannes Berg
Newer devices have 20 (5000 series) or 30 (6000 series) hardware queues, rather than the 16 that 4965 had. This was added to the driver a long time ago, but improperly: the queue registers for the higher queues aren't just continuations of the registers for the first 16 queues, they are in other places. Therefore, the hardware would lock up when trying to activate queue 16 or above and the device would have to be restarted. Thanks goes to Emmanuel who identified this and told me how the queue programming should be done. Note that we don't use queues 20 and higher today and doing so needs more work than this.

2012-04-23ipw2200: Fix race condition in the command completion acknowledgeStanislav Yakovlev
Driver incorrectly validates command completion: instead of waiting for a command to be acknowledged it continues execution. Most of the time driver gets acknowledge of the command completion in a tasklet before it executes the next one. But sometimes it sends the next command before it gets acknowledge for the previous one. In such a case one of the following error messages appear in the log: Failed to send SYSTEM_CONFIG: Already sending a command. Failed to send ASSOCIATE: Already sending a command. Failed to send TX_POWER: Already sending a command. After that you need to reload the driver to get it working again. This bug occurs during roaming (reported by Sam Varshavchik) https://bugzilla.redhat.com/show_bug.cgi?id=738508 and machine booting (reported by Tom Gundersen and Mads Kiilerich) https://bugs.archlinux.org/task/28097 https://bugzilla.redhat.com/show_bug.cgi?id=802106 This patch doesn't fix the delay issue during firmware load.

2012-04-23ath9k: fix tx power settings for AR9287Gabor Juhos
The 'ath9k_hw_update_regulatory_maxpower' helper function has been introduced by commit a55f858852e4345d0a31af593c46738ca8614bff (ath9k_hw: Cleanup TX power calculation for AR9287). Updating of the max_power_level value has been moved into the helper function in that change, however the removed code from 'ath9k_hw_ar9287_set_txpower' has not been replaced with a call of the new helper function. Due to that missing call, retrieving tx power for 2x2 and 3x3 chainmask is not handled properly. During the calculation of the tx power for 2x2 and 3x3 chainmasks the values are reduced. Those reductions must be compensated during retrieving. Fix this by adding the missing call of the helper function.

2012-04-23ath9k: add an extra boolean parameter to ath9k_hw_apply_txpowerGabor Juhos
In order to unifying regulatory limit handling commit ca2c68cc7bc80fc4504fb420df04cce99c9ee6ec (ath9k_hw: clean up tx power handling) introduced a new helper function 'ath9k_hw_apply_txpower', and the direct calls of 'ah->eep_ops->set_txpower' has been replaced by a call of the helper function. This caused a change in the behaviour of the 'ath9k_hw_set_txpowerlimit' function. The purpose of that function is to calculate and store the rate txpower table and the regulatory limit without touching the hardware registers. Before the commit, the 'test' parameter of the function was passed to the 'ah->eep_ops->set_txpower'. Now the calling of the 'set_txpower' function happens indirectly through 'ath9k_hw_apply_txpower', so the 'test' argument of the 'set_txpower' is always 'false'. This patch restores the original behaviour of 'ath9k_hw_set_txpowerlimit' by adding a new argument to 'ath9k_hw_apply_txpower.'

This is reported for two cases in https://bugzilla.kernel.org/show_bug.cgi?id=42775. The first case has the lock originating from within rtlwifi and could be fixed by rearranging the locking; however, the second originates from within mac80211.

2012-04-09rtlwifi: Fix oops on rate-control failureLarry Finger
When the rate-control indexing is incorrectly set up, mac80211 issues a warning and returns NULL from the call to ieee80211_get_tx_rate(). When this happens, avoid a NULL pointer dereference.

Before the switch to asynchronous firmware loading (mainline commit b0302ab), it was necessary to load firmware when initializing the first of the units in a dual-mac system. After the change, it is necessary to load firmware in both units. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-04-05Merge branch 'akpm' (Andrew's patch-bomb)Linus Torvalds
Merge batch of fixes from Andrew Morton: "The simple_open() cleanup was held back while I wanted for laggards to merge things. I still need to send a few checkpoint/restore patches. I've been wobbly about merging them because I'm wobbly about the overall prospects for success of the project. But after speaking with Pavel at the LSF conference, it sounds like they're further toward completion than I feared - apparently davem is at the "has stopped complaining" stage regarding the net changes. So I need to go back and re-review those patchs and their (lengthy) discussion." * emailed from Andrew Morton <akpm@linux-foundation.org>: (16 patches) memcg swap: use mem_cgroup_uncharge_swap fix backlight: add driver for DA9052/53 PMIC v1 C6X: use set_current_blocked() and block_sigmask() MAINTAINERS: add entry for sparse checker MAINTAINERS: fix REMOTEPROC F: typo alpha: use set_current_blocked() and block_sigmask() simple_open: automatically convert to simple_open() scripts/coccinelle/api/simple_open.cocci: semantic patch for simple_open() libfs: add simple_open() hugetlbfs: remove unregister_filesystem() when initializing module drivers/rtc/rtc-88pm860x.c: fix rtc irq enable callback fs/xattr.c:setxattr(): improve handling of allocation failures fs/xattr.c:listxattr(): fall back to vmalloc() if kmalloc() failed fs/xattr.c: suppress page allocation failure warnings from sys_listxattr() sysrq: use SEND_SIG_FORCED instead of force_sig() proc: fix mount -t proc -o AAA
2012-04-05simple_open: automatically convert to simple_open()Stephen Boyd
Many users of debugfs copy the implementation of default_open() when they want to support a custom read/write function op. This leads to a proliferation of the default_open() implementation across the entire tree. Now that the common implementation has been consolidated into libfs we can replace all the users of this function with simple_open(). This replacement was done with the following semantic patch: <smpl> @ open @ identifier open_f != simple_open; identifier i, f; @@ -int open_f(struct inode *i, struct file *f) -{ ( -if (i->i_private) -f->private_data = i->i_private; | -f->private_data = i->i_private; ) -return 0; -} @ has_open depends on open @ identifier fops; identifier open.open_f; @@ struct file_operations fops = { ... -.open = open_f, +.open = simple_open, ... }; </smpl> [akpm@linux-foundation.org: checkpatch fixes] Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
