This fixes hidden bugs in the size handling of the DMA buffers. This sets the RX buffer size to the theoretical max packet size and fixes passing of the size values to the device (must not subtract the header offset). These bugs are hidden and don't actually trigger due to the magic +100 offset for the buffer size. Signed-off-by:

Move the DMA stop sanity check up a few lines, so it's actually theoretically possible to trigger. (But it still shouldn't trigger, of course). Signed-off-by:

Passing beacons received from other BSS to s/w in non-scanning state is unnecessary in STA mode. This patch filters them out in h/w. Signed-off-by:

When iwlwifi runs on IOMMU, IOMMU generates a lot of PTE write faults because PTE write bit is not set on some of PTE's. This is because iwlwifi driver calls DMA mapping with PCI_DMA_TODEVICE which is read only in mapping PTE. But iwlwifi device actually writes to the mapped page to update its contents. This issue is not exposed in swiotlb. But VT-d hardware can capture this fault and stop the fault transaction. The iwl TX command contains a scratch field that is updated by uCode to indicate retry counts. For 5000 series the patch is required also for regular frames, but this patch does not differenciate.

at76_debug should be an unsigned int as it used as a bit field. In fact, modprobe fails when trying to set at76_debug's high bit. Signed-off-by:

With the latest mac80211 stack, the driver needs to be updated for cfg80211 scanning. I based the changes off of modifications for at76_usb found here: http://johannes.sipsolutions.net/patches/old/all/2008-09-19-13:35/020-cfg80211-scan.patch The trick was that max_signal also needs to be set to avoid a divide by zero Oops. I just guessed and used the value 100 for now. kvalo: handpicked the change from two different patches Signed-off-by:

Default to MAX_UCODE_BEACON_INTERVAL if the output of iwl_adjust_beacon_interval would otherwise be zero. This prevents a division by zero on my iwl5300-equipped Lenovo T400 with kernels that include "mac80211: use cfg80211s BSS infrastructure". This patch is a bit of a hack -- I'm not sure why iwl_setup_rxon_timing is giving iwl_adjust_beacon_interval a zero input (which is the only way it would output zero). I would be happy to have a better fix. But for now, this makes my box boot... Signed-off-by: -

Scanned BSS entries are timestamped with jiffies, which doesn't increment across suspend and hibernate. On resume, every BSS in the scan list looks like it was scanned within the last 10 seconds, irregardless of how long the machine was actually asleep. Age scan results on resume with the time spent during sleep so userspace has a clue how old they really are. Signed-off-by:

The previous patch made cfg80211 generally aware of the signal type a given hardware will give, so now it can implement SIOCGIWRANGE itself, removing more wext stuff from mac80211. Might need to be a little more parametrized once we have more hardware using cfg80211 and new hardware capabilities. Signed-off-by:

It wasn't a good idea to make the signal type a per-BSS option, although then it is closer to the actual value. Move it to be a per-wiphy setting, update mac80211 to match. Signed-off-by:

Some APs don't start BA negotiation with the client before it is done with the key handshake in WPA/RSN. With those APs, key handshake times out if EAPOL frames are sent after addba request. So defer the BA negotiation until we are done with tx/rx of all EAPOL frames. Signed-off-by:

Due to various bugs in the software stack we end up having to fill qual.qual; level should be used, but wpa_supplicant doesn't properly ignore qual.qual, NM should use qual.level regardless of that because qual.qual is 0 but doesn't handle IW_QUAL_DBM right now. So fill qual.qual with the qual.level value clamped to -110..-40 dBm or just the regular 'unspecified' signal level. This requires a mac80211 change to properly announce the max_qual.qual and avg_qual.qual values. Signed-off-by:

The word_base is in bytes instead of word index number, this means that when using it, it should be transformed into a word index first. Otherwise RF register reading will fail through debugfs since we would start reading 4 words starting with word 4 (which is the last valid word for RF). Signed-off-by:

The TX/RX packet counters are needed to fill in RADIUS Accounting attributes Acct-Output-Packets and Acct-Input-Packets. We already collect the needed information, but only the TX/RX bytes were previously exposed through nl80211. Allow applications to fetch the packet counters, too, to provide more complete support for accounting. Signed-off-by:

This extends the NL80211_CMD_TRIGGER_SCAN command to allow applications to specify a set of information element(s) to be added into Probe Request frames with NL80211_ATTR_IE. This provides support for the MLME-SCAN.request primitive parameter VendorSpecificInfo and can be used, e.g., to implement WPS scanning. Signed-off-by:

We currently send beacons directly from the interrupt routine. This can hold up interrupt processing in beaconing modes and makes the ISR somewhat more complex. Move it to a tasklet like rx and tx. Changes-licensed-under: 3-Clause-BSD Signed-off-by:

ath5k_reset can be called from process context, which in turn can call ath5k_beacon_config which takes the sc->block spinlock. Since it can also be taken in hard irq context, use spin_lock_irqsave everywhere. This fixes a potential deadlock in adhoc mode.

Since interrupts are already masked by the hardware, there's no need to discard interrupt bits in the ISR itself. Also, in ath5k_beacon_config we mask off a couple of bits without locking, so doing this mask in software can lead to unhandled beacon timer and beacon miss interrupts.
