2012-01-24iwlwifi: fix PCI-E transport "inta" raceJohannes Berg
When an interrupt comes in, we read the reason bits and collect them into "trans_pcie->inta". This happens with the spinlock held. However, there's a bug resetting this variable -- that happens after the spinlock has been released. This means that it is possible for interrupts to be missed if the reset happens after some other interrupt reasons were already added to the variable. I found this by code inspection, looking for a reason that we sometimes see random commands time out. It seems possible that this causes such behaviour, but I can't say for sure right now since it happens extremely infrequently on my test systems.

2012-01-16ath9k_hw: fix interpretation of the rx KeyMiss flagFelix Fietkau
Documentation states that the KeyMiss flag is only valid if RxFrameOK is unset, however empirical evidence has shown that this is false. When KeyMiss is set (and RxFrameOK is 1), the hardware passes a valid frame which has not been decrypted. The driver then falsely marks the frame as decrypted, and when using CCMP this corrupts the rx CCMP PN, leading to connection hangs.

2012-01-13rt2800pci: fix spurious interrupts generationStanislaw Gruszka
Same devices can generate interrupt without properly setting bit in INT_SOURCE_CSR register (spurious interrupt), what will cause IRQ line will be disabled by interrupts controller driver. We discovered that clearing INT_MASK_CSR stops such behaviour. We previously first read that register, and then clear all know interrupt sources bits and do not touch reserved bits. After this patch, we write to all register content (I believe writing to reserved bits on that register will not cause any problems, I tested that on my rt2800pci device). This fix very bad performance problem, practically making device unusable (since worked without interrupts), reported in: https://bugzilla.redhat.com/show_bug.cgi?id=658451 We previously tried to workaround that issue in commit 4ba7d9997869d25bd223dea7536fc1ce9fab3b3b "rt2800pci: handle spurious interrupts", but it was reverted in commit 82e5fc2a34fa9ffea38f00c4066b7e600a0ca5e6 as thing, that will prevent to detect real spurious interrupts.

2012-01-13ipw2x00: signedness bug handling frame lengthDan Carpenter
This is basically just a cleanup. Large positive numbers get counted as negative but then get implicitly cast to positive again for the checks that matter. This does make a small difference in ipw_handle_promiscuous_rx() when we test "if (unlikely((len + IPW_RX_FRAME_SIZE) > skb_tailroom(rxb->skb)))" It should return there, but we don't return until a couple lines later when we test "if (len > IPW_RX_BUF_SIZE - sizeof(struct ipw_rt_hdr)) {". The difference is that in the second test the sizeof() means that there is an implied cast to unsigned.

2012-01-12brcmsmac: fix reading of PCI sprom contentsLinus Torvalds
It appears that you can only read the sprom contents with aligned 16-bit reads: anything else causes at least some versions of the broadcom chipset to abort the PCI transaction, returning 0xff. This apparently doesn't trigger very often, because most setups don't use an external srom chip, and the OTP sprom loading doesn't have this issue. But at least the current 11" Macbook Air does trigger it, and wireless communications were broken as a result.

The commit "ath9k: Fix invalid noisefloor reading due to channel update" preserves the current channel noisefloor readings before updating channel type at the same channel index. It is also updating the curchan pointer. As survey updation is also referring curchan pointer to fetch the appropriate index, which might leads to invalid memory access. This patch partially reverts the change and stores the noise floor history buffer before updating channel type w/o updating curchan.

2012-01-04iwlegacy: move some i/o helpers out of inlineStanislaw Gruszka
This save us about 20k of text size, and should have no impact on performance as hot paths do not use much I/O.

2012-01-04iwlegacy: off by one in iwl3945_hw_build_tx_cmd_rate()Dan Carpenter
We use "rate_index" like this: rate = iwl3945_rates[rate_index].plcp; The iwl3945_rates[] array has IWL_RATE_COUNT_3945 elements so the limit here is off by one.
