2012-06-28net: Use NLMSG_DEFAULT_SIZE in combination with nlmsg_new()Thomas Graf1-1/+1
Using NLMSG_GOODSIZE results in multiple pages being used as nlmsg_new() will automatically add the size of the netlink header to the payload thus exceeding the page limit. NLMSG_DEFAULT_SIZE takes this into account.

Conflicts: drivers/net/caif/caif_hsi.c drivers/net/usb/qmi_wwan.c The qmi_wwan merge was trivial. The caif_hsi.c, on the other hand, was not. It's a conflict between 1c385f1fdf6f9c66d982802cd74349c040980b50 ("caif-hsi: Replace platform device with ops structure.") in the net-next tree and commit 39abbaef19cd0a30be93794aa4773c779c3eb1f3 ("caif-hsi: Postpone init of HIS until open()") in the net tree.

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless John Linville says: ==================== Amitkumar Karwar gives us two mwifiex fixes: one fixes some skb manipulations when handling some event messages; and another that does some similar fixing on an error path. Avinash Patil gives us a fix for for a memory leak in mwifiex. Dan Rosenberg offers an NFC NCI fix to enforce some message length limits to prevent buffer overflows. Eliad Peller provides a mac80211 fix to prevent some frames from being built with an invalid BSSID. Eric Dumazet sends an NFC fix to prevent a BUG caused by a NULL pointer dereference. Felix Fietkau has an ath9k fix for a regression causing LEAP-authenticated connection failures. Johannes Berg provides an iwlwifi fix that eliminates some log SPAM after an authentication/association timeout. He also provides a mac80211 fix to prevent incorrectly addressing certain action frames (and in so doing, to comply with the 802.11 specs). Larry Finger provides a few USB IDs for the rtl8192cu driver -- should be harmless. Panayiotis Karabassis provices a one-liner to fix kernel bug 42903 (a system freeze). Randy Dunlap provides a one-line Kconfig change to prevent build failures with some configurations. Stone Piao provides an mwifiex sequence numbering fix and a fix to prevent mwifiex from attempting to include eapol frames in an aggregation frame. Finally, Tom Hughes provides an ath9k fix for a NULL pointer dereference. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2012-06-28mwifiex: retrieve correct max_power information in reg_notifier handlerAmitkumar Karwar1-3/+3
As we don't provide custom regulatory rules to cfg80211, "chan->max_power" remains uninitialized (0dbm) and "chan->max_reg_power" will contain maximum power for a channel extracted from regulatory rules provided by CRDA; hence use "chan->max_reg_power" in reg_notifier handler instead of "chan->max_power" to set max_power in firmware.

2012-06-28mwifiex: wakeup main thread to handle command queuedAmitkumar Karwar5-28/+7
We miss to wakeup main thread after adding command to cmd pending queue at follwing places. These commands are handled later when main thread is woken up for handling an interrupt for sleep event from firmware. This adds worst case delay of 50msec. 1) We don't wakeup main thread when asynchronous command is added to cmd pending queue. Move queue_work() call from mwifiex_wait_queue_complete() to mwifiex_send_cmd_async() to wakeup main thread for sync as well as async commands. 2) Scan operation is triggered due to following reasons a) request from user (ex. "iw scan" command) b) Scan performed by driver internally. In first case main thread is woken up when first scan command is queued in cmd pending queue (we don't need to wakeup main thread for subsequent scan commands, because they are queued in scan command response handler), but it is not done for second case. queue_work() is moved inside mwifiex_scan_networks() to handle both the cases.

2012-06-28ath9k: fix ANI operation in AP modeFelix Fietkau2-15/+15
ath9k_ani_reset (which is called at reset time) uses a state variable ani->update_ani to prevent the ANI noise immunity state on the operating channel from being overwritten by background scans. Unfortunately this is also being set for AP mode, since it's mixed with code that is only supposed to change the default settings after a reset. In AP mode this has the side effect of having ANI run, but being unable to change its runtime noise immunity level, making it effectively useless. Fix this by getting rid of ani->update_ani and passing a parameter to ath9k_hw_set_ofdm_nil and ath9k_hw_set_cck_nil instead.

But the code currently uses wd_timeout in the first error. wd_timeout will generally be set at IL_DEF_WD_TIMEOUT (ie, 2000).

2012-06-26wlcore: print stack trace in every recoveryEyal Shapira2-1/+2
As recovery queuing can now occur from multiple code paths it's convenient to know what triggered it in all cases other than an intended recovery which is part of the switch between single role to multi role.

2012-06-26wlcore: queue recovery in case of bus errors during cmd_remove_peerEyal Shapira1-10/+19
Following the addition of propagating errors from the bus ops there's a need to distinguish between bus errors (including timeout) and a legitimate timeout occuring in cmd_wait_for_event_or_timeout. In case of real bus errors we need to queue recovery even in cases where a timeout on a response from the FW to a command is acceptable.

2012-06-26wlcore: fix broken TX due to wrong queuing of recoveryEyal Shapira1-11/+24
commit 14bba17b "wl12xx: Propagate errors from wl1271_raw_write32" breaks down TX in certain scenarios. wl1271_irq_locked() propagates errors from wl1271_tx_work_locked however it may return -EBUSY when the FW queues are full which is a legitimate case and not a a real error. In this case a recovery is triggered by wl1271_irq and this keeps repeating itself so TX is completely broken. Fix it by avoiding propagating return values as errors even if they aren't. Only bus (SDIO or SPI) ops failures would be progagated as only these should trigger recovery. Signed-off-by: Eyal Shapira <eyal@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

2012-06-26wl18xx: deprecate PG1 supportLuciano Coelho2-57/+22
The new PG2 version of the chip has a few differences in terms of FW API if compared to PG1. PG1 is just a sample that shouldn't be used in real life, so to avoid having to handle both separately, mark the PG1 version as deprecated and bail out during probe.

2012-06-25iwlwifi: fix activating inactive stationsJohannes Berg1-0/+12
When authentication/association timed out, the driver would complain bitterly, printing the message ACTIVATE a non DRIVER active station id ... addr ... The cause turns out to be that when the AP station is added but we don't associate, the IWL_STA_UCODE_INPROGRESS is set but never cleared. This then causes iwl_restore_stations() to attempt to resend it because it uses the flag internally and uploads even if it didn't set it itself. To fix this issue and not upload the station again when it has already been removed by mac80211, clear the flag after adding it in case we add it only for association.

2012-06-25ath9k: fix dynamic WEP related regressionFelix Fietkau3-1/+7
commit 7a532fe7131216a02c81a6c1b1f8632da1195a58 ath9k_hw: fix interpretation of the rx KeyMiss flag This commit used the rx key miss indication to detect packets that were passed from the hardware without being decrypted, however it seems that this bit is not only undefined in the static WEP case, but also for dynamically allocated WEP keys. This caused a regression when using WEP-LEAP. This patch fixes the regression by keeping track of which key indexes refer to CCMP keys and only using the key miss indication for those.

2012-06-23wlcore: refactor threaded IRQ routineArik Nemtsov1-31/+31
Separate the threaded IRQ handling routine into two functions. The outer function takes the mutex and calls recovery on errors. It also performs a Tx-path optimization to avoid redundant works. The inner function is simplified - all calls to recovery are removed and it assumes the lock is taken. The locked variant will be reused elsewhere.
