ath9k_rx_skb_preprocess nulls rxs and the mactime is never set again - mactime is always 0. This causes problems in IBSS mode. ieee80211_rx_bss_info uses mactime to decide if an IBSS merge is needed. Without this patch the merge is triggered by each beacon received. This can be recognized by the "beacon TSF higher than local TSF - IBSS merge with BSSID" log message accompanying each beacon. This problem was not completely fixed in commit a6d2055b and is not a stable kernel fix. It is solely intended for wireless-testing. Signed-off-by:

I noticed a possible issue in the paused flag management of the ath_atx_tid data structure. In particular, in a noisy environment and under heavy load, I observed that the AGGR session establishment could fail several times consecutively causing values of the paused flag greater than one for this TID (ath_tx_pause_tid is called more than once from ath_tx_aggr_start). Considering that the session for this TID can not be established also after the mac80211 stack calls the ieee80211_agg_tx_operational() since the ath_tx_aggr_resume() lowers the paused flag only by one. This patch also replaces some BUG_ON calls with WARN_ON, as even if these unlikely conditions happen, it's not fatal enough to justify a BUG_ON. Signed-off-by:

AR9003 was not relying on the CTL indexes from the EEPROM for capping the max output power. The CTL indexes from the EEPROM provide calibrated limits for output power for each tested and supported frequency. Without this the device operates at a power level which only conforms to the transmit spectrum mask as specified by IEEE Annex I.2.3. The regulatory limit by CRDA is always used but does not provide calibrated values for optimal performance, specially on band edges. Using the calibrated data from the EEPROM ensures the device operates at optimal output power while still ensuring proper regulatory compliance. The device uses the minimum of these tree values, the value from CRDA, the calibrated value from CTL indexex, and the value to conform to the IEEE transmit spectrum mask. Signed-off-by:

It is a uCode bug which cause the tx queue id not match scd_flow in compressed block ack frame, and it need to be addressed in uCode. Currently, driver will log the information when it happen. Since it is possible happen very often and we do not want to fill the syslog, so don't enable the logging by default. Signed-off-by:

On AR5008-AR9002, other forms of calibration must not be started while the noise floor calibration is running, as this can create invalid readings which were sometimes not even recoverable by any further calibration attempts. This patch also ensures that the result of noise floor measurements are processed faster and also allows the result of the initial calibration on reset to make it into the NF history buffer Signed-off-by:

The noise floor history buffer is currently not kept per channel, which can lead to problems when changing channels from a clean channel to a noisy one. Also when switching from HT20 to HT40, the noise floor history buffer is full of measurements, but none of them contain data for the extension channel, which it needs quite a bit of time to recover from. This patch puts all the per-channel calibration data into a single data structure, and gives the the driver control over whether that is used per-channel or even not used for some channels. For ath9k_htc, I decided to keep this per-channel in order to avoid creating regressions. For ath9k, the data is kept only for the operating channel, which saves some space. ath9k_hw takes care of wiping old data when the operating channel or its channel flags change. Signed-off-by:

Previously the software scan callback was used to indicate to the hardware, when it was safe to calibrate. This didn't really work properly, because it depends on a specific order of software scan callbacks vs. channel changes. Also, software scans are not the only thing that triggers off-channel activity, so it's better to use the newly added indication from mac80211 for this and not use the software scan callback for anything calibration related. This fixes at least some of the invalid noise floor readings that I've seen in AP mode on AR9160 Signed-off-by:

The periodic noise floor calibration is broken on this chip family, because it keeps triggering a software-filtered noise floor calibration, but never reads the result before uploading the history buffer value to the hardware. Fix this with a call to ath9k_hw_getnf(), just like on AR9002. Signed-off-by:

On AR9003 the initial noise floor calibration is currently triggered at the end of the reset without allowing the hardware to update the baseband settings. This could potentially make scans in noisy environments a bit more unreliable, so use the same calibration sequence that is used on AR9002. Signed-off-by:

commit f84b29ec Author: Johannes Berg <johannes.berg@intel.com> Date: Tue May 18 02:29:13 2010 -0700 iwlwifi: queue user-initiated scan when doing internal scan introduced a potential deadlock because it calls ieee80211_scan_completed() with the priv->mutex held, but mac80211 may call back into iwlwifi which would lead to recursive locking. Move this out from under the mutex. Cc: stable@kernel.org Signed-off-by:

Marvell 88ec048 is a derivative of its 88e1121r device. From the programmer's perspective, the one major difference is the addition of an additional control bit in Page 2 Register 16 - used to control the padding of odd nibble preambles. This patch adds support for this new device, while inheriting as much code as possible from the existing 88e1121r implementation. Signed-off-by:

This patch addresses an issue seen on 82580 in which the MDICNFG register will be reset during a single function reset and as a result we will be unable to communicate with the PHY.

Commit fc6055a5 (net: Introduce skb_orphan_try()) allows an early orphan of the skb and takes care on tx timestamping, which needs the sk-reference in the skb on driver level. So does the can-raw socket, which has not been taken into account here. The patch below adds a 'prevent_sk_orphan' bit in the skb tx shared info, which fixes the problem discovered by Matthias Fuchs here: http://marc.info/?t=128030411900003&r=1&w=2 Even if it's not a primary tx timestamp topic it fits well into some skb shared tx context. Or should be find a different place for the information to protect the sk reference until it reaches the driver level? Signed-off-by:

This reverts commit 15e83ed7. As explained by Johannes Berg, the optimization made here is invalid. Or, at best, incomplete. Not only destructor invocation, but conntract entry releasing must be executed outside of hw IRQ context. So just checking "skb->destructor" is insufficient. Signed-off-by:

The pm_qos_add_request call has to register the pm_qos request with the pm_qos susbsystem before first use of the pm_qos request via pm_qos_update_request. As pm_qos changed to use plists there is no benefit in registering and unregistering the pm_qos request on ifup/ifdown and thus we move the registering into e1000_open and the unregistering in e1000_close. This fixes the following warning: [ 1.786060] WARNING: at kernel/pm_qos_params.c:264 pm_qos_update_request+0x28/0x54() [ 1.786088] Hardware name: Latitude E6500 [ 1.787045] pm_qos_update_request() called for unknown object [ 1.787966] Modules linked in: [ 1.788940] Pid: 1, comm: swapper Not tainted 2.6.35-rc5-mmotm0719 #1 [ 1.790035] Call Trace: [ 1.791121] [<ffffffff81037335>] warn_slowpath_common+0x80/0x98 [ 1.792205] [<ffffffff810373e1>] warn_slowpath_fmt+0x41/0x43 [ 1.793279] [<ffffffff81057c14>] pm_qos_update_request+0x28/0x54 [ 1.794347] [<ffffffff8134889e>] e1000_configure+0x421/0x459 [ 1.795393] [<ffffffff8134afbd>] e1000_open+0xbd/0x37c [ 1.796436] [<ffffffff8105743a>] ? raw_notifier_call_chain+0xf/0x11 [ 1.797491] [<ffffffff8145f948>] __dev_open+0xae/0xe2 [ 1.798547] [<ffffffff8145f997>] dev_open+0x1b/0x49 [ 1.799612] [<ffffffff8146e36e>] netpoll_setup+0x84/0x259 [ 1.800685] [<ffffffff81b5037c>] init_netconsole+0xbc/0x21f [ 1.801744] [<ffffffff81b5026c>] ? sir_wq_init+0x0/0x35 [ 1.802793] [<ffffffff81b502c0>] ? init_netconsole+0x0/0x21f [ 1.803845] [<ffffffff810002ff>] do_one_initcall+0x7a/0x12f [ 1.804885] [<ffffffff81b2ccae>] kernel_init+0x138/0x1c2 [ 1.805915] [<ffffffff81003554>] kernel_thread_helper+0x4/0x10 [ 1.806937] [<ffffffff81590e00>] ? restore_args+0x0/0x30 [ 1.807955] [<ffffffff81b2cb76>] ? kernel_init+0x0/0x1c2 [ 1.808958] [<ffffffff81003550>] ? kernel_thread_helper+0x0/0x10 [ 1.809958] ---[ end trace 84b562a00a60539e ]--- Signed-off-by:
