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: NMichael Buesch <mb@bu3sch.de> Signed-off-by: NJohn W. Linville <linville@tuxdriver.com>

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.

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.

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: NJohn W. Linville <linville@tuxdriver.com>

Scanned BSS entries are timestamped with jiffies, which doesn't increment across suspend and hibernate.

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: NVasanthakumar Thiagarajan <vasanth@atheros.com> Signed-off-by: NJohn W. Linville <linville@tuxdriver.com>

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).

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.

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.

The only way rf_write() can be called with word 0 is when the user sends the wrong word index through debugfs. However the values which are send through debugfs are validated using the RF_BASE and RF_SIZE macro values, the most logical solution is to increase RF_BASE with 4 and decrease RF_SIZE with 4 (RF_SIZE has always been 1 word too big) Signed-off-by: NIvo van Doorn <IvDoorn@gmail.com> Signed-off-by: NJohn W.

Fixes: - iwlwifi is an optional driver and should thus not default to 'y'. - 3945 now depends on IWLCORE. Rework: - There is not a case when IWLCORE should not be selected. At the same time the driver does not use IWLWIFI or IWLCORE. We can just merge the usage of these two. With IWLWIFI being the driver name we proceed to use just it and replace instances of IWLCORE with it. The module name does not change and is still iwlcore. - Both IWLAGN and IWL3945 are selecting FW_LOADER, we can thus just move this up to one select when IWLWIFI is selected. - IWL5000 now supports Intel Wireless Wifi 100, 6000, and 6050 series. - Now that 3945 depends on IWLWIFI we can also indicate its dependency on MAC80211_LEDS and LEDS_CLASS at this level. - IWLAGN_LEDS is not used by driver - remove it. - IWLAGN_SPECTRUM_MEASUREMENT actually depends on IWLWIFI as it forms part of iwlcore module. Move this config up in Kconfig to reflect that and also change name to IWLWIFI_SPECTRUM_MEASUREMENT. - CONFIG_IWLWIFI_RFKILL is used by iwlagn as well as iwl3945, add text to description that indicates this. - CONFIG_IWL3945_RFKILL does not exist - remove usage from driver. - Add "iwlagn" to end of description of IWLAGN to help people understand what iwlagn means in rest of Kconfig text. - Add "iwl3945" to end of description of IWL3945 to help people understand what iwlagn means in rest of Kconfig text. - Change IWLWIFI_DEBUGFS description to indicate that only iwlagn supports it (for now).
