defs.meshie.val.mesh_id is 32 chars long. It's not supposed to be NUL terminated. This code puts a terminator on the end to make it easier to print to sysfs. The problem is that if the mesh_id fills the entire buffer the original code puts the terminator one spot past the end. The way the original code was written, there was a check to make sure that maxlen was less than PAGE_SIZE. Since we know that maxlen is at most 34 chars, I just removed the check. Signed-off-by:

The hardware rx filter flag triggered by FIF_PROMISC_IN_BSS is overly broad and covers even frames with PHY errors. When this flag is enabled, this message shows up frequently during scanning or hardware resets: ath: Could not stop RX, we could be confusing the DMA engine when we start RX up Since promiscuous mode is usually not particularly useful, yet enabled by default by bridging (either used normally in 4-addr mode, or with hacks for various virtualization software), we should sacrifice it for better reliability during normal operation. This patch leaves it enabled if there are active monitor mode interfaces, since it's very useful for debugging. Signed-off-by:

While working on PS I've noticed elp_work is kicking rather often, and sometimes the chip is put to sleep before 5ms delay expires. This seems to happen because by the time wl1251_ps_elp_wakeup is called elp_work might still be pending. After wakeup is done, the processing may take some time, during which 5ms might expire and elp_work might get scheduled. In this case, ss soon as 1st thread finishes work and releases the mutex, elp_work will then put the device to sleep without 5ms delay. In addition 1st thread will queue additional elp_work needlessly. Fix this by cancelling work in wl1251_ps_elp_wakeup instead. Signed-off-by:

wl1251_ps_set_elp() only does acx_sleep_auth call and takes the chip from/to ELP, however all callers of wl1251_ps_set_mode() have already taken the chip out of ELP and puts it back to ELP when they finish. This makes ELP calls (and register writes they result in) superfluous. So remove wl1251_ps_set_elp function and call acx_sleep_auth directly. Signed-off-by:

Regulatory devices issue change uevents to inform userspace of a need to call the crda tool; however these can often be sent before udevd is running, and were not previously included in the results of udevadm trigger (which requests a new change event using the /uevent attribute of the sysfs object). Add a uevent function to the device type which includes the COUNTRY information from the last request if it has yet to be processed, the case of multiple requests is already handled in the code by checking whether an unprocessed one is queued in the same manner and refusing to queue a new one. The existing udev rule continues to work as before. Signed-off-by:

The scan code has a race that Michael reported he ran into, but it's easy to fix while at the same time simplifying the code. The race resulted in the following warning: ------------[ cut here ]------------ WARNING: at net/mac80211/scan.c:310 ieee80211_rx_bss_free+0x20c/0x4b8 [mac80211]() Modules linked in: [...] [<c0033edc>] (unwind_backtrace+0x0/0xe0) from [<c004f2a4>] (warn_slowpath_common+0x4c/0x64) [... backtrace wasn't useful ...] Reported-by:

Usually H/W generate statistics notify once per about 100ms, but sometimes we can receive notify in shorter time, even 2 ms. This can be problem for plcp health and ack health checking. I.e. with 2 plcp errors happens randomly in 2 ms duration, we exceed plcp delta threshold equal to 100 (2*100/2). Also checking ack's in short time, can results not necessary false positive and firmware reset, for example when channel is noised and we do not receive ACKs frames or when remote device does not send ACKs at the moment. Patch change code to do statistic check and possible recovery only if 99ms elapsed from last check. Forced delay should assure we have good statistic data to estimate hardware state. Signed-off-by:

In the spirit of optimizing the code to get the queue structure of TX queues, also optimize the code to get beacon queues. We can simply use the bcn queue field of the rt2x00_dev structure instead of using the rt2x00queue_get_queue function. Signed-off-by:

The ATIM queue is considered to be a TX queue by the drivers that support the queue. Therefore include support for the ATIM queue to the rt2x00queue_get_tx_queue function so that the drivers that support the ATIM queue can also use that function. Add the support in such a way that drivers that do not support the ATIM queue are not penalized in their efficiency. Signed-off-by:

When setting up multiple BSSIDs in AP mode on an rt2800pci device we previously used the STAs AID to select an appropriate key slot. But since the AID is per VIF we can end up with two STAs having the same AID and thus using the same key index. This resulted in one STA overwriting the key information of another STA. Fix this by simply searching for the next unused entry in the pairwise key table. Also bring the key table init in sync with deleting keys by initializing the key table entries to 0 instead of 1.

ieee80211_get_tx_rate is not valid for HT rates. Hence, restructure the TX desciptor creation to be aware of MCS rates. The generic TX desciptor creation now cares about the rate_mode (CCK, OFDM, MCS, GF). As a result, ieee80211_get_tx_rate gets only called for legacy rates. Acked-by:

HT and no-HT rt2x00 devices use a partly different TX descriptor. Optimize the tx desciptor memory layout by putting the PLCP and HT substructs into a union and introduce a new driver flag to decide which TX desciptor format is used by the device. This saves us the expensive PLCP calculation fOr HT devices and the HT descriptor setup on no-HT devices. Acked-by:

Newer devices like rt2800* own a hardware sequence counter and thus don't need to use a software sequence counter at all. Add a new driver flag to shortcut the software sequence number generation on devices that don't need it. rt61pci, rt73usb and rt2800* seem to make use of a hw sequence counter while rt2400pci and rt2500* need to do it in software.
