Scan requesting doesn't need to be asynchronous since all code paths leading up to it can sleep. Make the scan request a new util operation that is hw-specific (to account for 3945 vs. agn) and call it right in place. This patch moves a lot of code into iwlagn as it need not be in iwlcore.

I keep checking what "priv->scan" is, so rename it to "priv->scan_cmd" which more clearly tells us what it is. Signed-off-by:

Since we no longer do a multi-pass scan, keeping track of how long each pass took is pointless since there will only be one. Signed-off-by:

This logic is just confusing, if anything it belongs into mac80211. Also, even if we do scan during the EAPOL handshake, that will not cause any problems, just a short delay. Signed-off-by:

Since mac80211 will now never request scanning multiple bands, we can remove all the associated logic and scan a single band only in each scan. Signed-off-by:

Even the initial single/dual stream values will be overridden later when issue link quality command; but still make sense not to use hard-code value during initialization. Single/Dual stream mask are used to indicate the best antenna for SISO/MIMO; different NIC has different tx antenna configuration; so the parameter need to based on the valid tx antenna. 1x2 device: single tx antenna available, only SISO is valid configuration, but still need to set up MIMO configuration, so set it up with antenna A & B as default. 2x2 device: two tx antenna available, dual_stream will use both valid antenna. 3x3 device: three tx antenna available, skip the first antenna and choice the second and third antenna for dual_stream.

When an internal scan is started, nothing protects the is_internal_short_scan variable which can cause crashes, cf. https://bugzilla.kernel.org/show_bug.cgi?id=15667. Fix this by making the short scan request use the mutex for locking, which requires making the request go to a work struct so that it can sleep. Reported-by:

This patch fixes two warnings below after unplugging ar9271 usb device: -one is a kernel warning[1] -another is a lockdep warning[2] The root reason is that __skb_queue_purge can't be executed in hardirq context, so the patch forks ath9k_skb_queue_purge(ath9k version of _skb_queue_purge), which frees skb with dev_kfree_skb_any which can be run in hardirq context safely, then prevent the lockdep warning and kernel warning after unplugging ar9271 usb device.

We get RXORN interrupts when all receive buffers are full. This is not necessarily a fatal situation. It can also happen when the bus is busy or the CPU is not fast enough to process all frames. Older chipsets apparently need a reset to come out of this situration, but on newer chips we can treat RXORN like RX, as going thru a full reset does more harm than good, there. The exact chip revisions which need a reset are unknown - this guess AR5K_SREV_AR5212 ("venice") is copied from the HAL. Inspired by openwrt 413-rxorn.patch: "treat rxorn like rx, reset after rxorn seems to do more harm than good" Signed-off-by:Bruno Randolf <br1@einfach.org> Signed-off-by:

There was a confusion in the usage of the bits AR5K_STA_ID1_ACKCTS_6MB and AR5K_STA_ID1_BASE_RATE_11B. If they are set (1), we will get lower bitrates for ACK and CTS. Therefore ath5k_hw_set_ack_bitrate_high(ah, false) actually resulted in high bitrates, which i think is what we want anyways. Cleared the confusion and added some documentation. Signed-off-by:

The rt2800 version constants are inconsistent, and the version number don't mean a lot of things anyway. Refactor the constants to have some more meaningful names, and introduce and use some new helpers to check these chipset revisions. At the same time rename to revision, as they are more revision numbers rather than version numbers. Signed-off-by:

It seems that the distinction between RF channel switch method is solely based on the RF chipset that is used. Refactor the channel switch decision to just take the RF chipset into account, thereby greatly simplifying the check. Signed-off-by:

This patch fixes an old problem, which - under certain circumstances - could cause the device to become unresponsive. most of p54pci's rx-ring management is implemented in just two distinct standalone functions. p54p_check_rx_ring takes care of processing incoming data, while p54p_refill_rx_ring tries to replenish all depleted communication buffers. This has always worked fine on my fast machine, but now I know there is a hidden race... The most likely candidate here is ring_control->device_idx. Quintin Pitts had already analyzed the culprit and posted a patch back in Oct 2009. But sadly, no one's picked up on this. ( https://patchwork.kernel.org/patch/53079/ [2 & 3] ). This patch does the same way, except that it also prioritize rx data processing, simply because tx routines *can* wait. Reported-by:

We used to free all the Tx queues memory when interface is brought down and reallocate them again in interface up. This requires order-4 allocation for txq->cmd[]. In situations like s2ram, this usually leads to allocation failure in the memory subsystem. The patch fixed this problem by allocating the Tx queues memory only at the first time. Later iwl_down/iwl_up only initialize but don't free and reallocate them. The memory is freed at the device removal time. BTW, we have already done this for the Rx queue.

The last_phy_res[100] variable is used in an odd way. The first byte of it is used as a flag, and the rest as the data. Thus, the array need only be 61 bytes, since it is just the flag and a struct iwl_rx_phy_res (which is 60 bytes). Clean this up by splitting the variable into two: last_phy_res and last_phy_res_valid, using correct types for both (struct and bool). While doing all this also move the variables to the _agn part of the hw-specific union since they only apply to A-MPDUs. Signed-off-by:

Default WEP keys and regular keys are not allocated from the same space in the firmware, so we shouldn't use the same bits to indicate in use. For default WEP keys, however, mac80211 won't allow using the same key index twice, so the check is not necessary at all -- add/remove are perfectly nested due to those checks. Other keys are allocated in the device in a global array that only has a certain number of slots, so for that we need to keep the allocation bitmap; but the 802.11 key index isn't relevant there.
