2014-03-13rtlwifi: rtl8723be: Fix array dimension problemsLarry Finger1-5/+9
Commit a619d1abe20c leads to the following static checker warning: drivers/net/wireless/rtlwifi/rtl8723be/phy.c:667 _rtl8723be_store_tx_power_by_rate() error: buffer overflow 'rtlphy->tx_power_by_rate_offset[band]' 4 <= 5 This warning arises because the code is testing the indices for the wrong maximum values. In addition, the tests merely putput a warning, and then procedes to corrupt memory. With this change, any such invalid memory access is avoided.

2014-03-06brcmfmac: Use atomic functions for intstatus update.Hante Meuleman1-14/+15
The intstatus in sdio code can be updated from different threads. To protect intstatus access, atomic functions are used. One of them is set_bit, but this function is not guaranteed atomic on all platforms. The loop was replaced with local created OR function.

iwlegacy version of this iwlwifi patch: commit aed7d9ac1836defe033b561f4306e39014ac56fd Author: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Date: Wed Feb 20 11:33:00 2013 +0200 iwlwifi: disable 8K A-MSDU by default Supporting 8K A-MSDU means that we need to allocate order 1 pages for every Rx packet. Even when there is no traffic. This adds stress on the memory manager. The handling of compound pages is also less trivial for the memory manager and not using them will make the allocation code run faster although I didn't really measure. Eric also pointed out that having huge buffers with little data in them is not very nice towards the TCP stack since the truesize of the skb is huge. This doesn't allow TCP to have a big Rx window. See https://patchwork.kernel.org/patch/2167711/ for details. Note that very few vendors will actually send A-MSDU. Disable this feature by default.

2014-03-04rtl818x: make sure TX descriptor writes are done before kicking DMAandrea merello1-0/+6
The TX descriptors are consumed by the HW using DMA. Even if in the driver code the TX descriptor writes appears before the HW "dma kick" register writes, the CPU may reorder them. If this happens, the TX may not happen at all becase the "valid" descriptor flag may have not been set yet. This patch adds a write memory barrier to ensures the TX descriptor is written before writing to the HW "dma kick" register.

2014-03-04rtl818x: Make sure the TX descriptor "valid" flag is written by lastandrea merello1-0/+5
The TX descriptors are consumed by the HW using DMA. Even if in the driver code the memory write that sets the "valid" flag appears after all other writes, the CPU may reorder writes, causing the HW to consider as valid a not-fully-written yet descriptor. This may cause HW incorrect behaviour. This can happen because (AFAIK) the HW may attempt DMA asynchronously without waiting to be kicked by the following register write. This patch adds a write memory barrier to enforce writes ordering.

2014-03-03ath9k_hw: tweak noise immunity thresholds for older chipsetsFelix Fietkau2-4/+23
Older chipsets are more sensitive to high PHY error counts, and the current noise immunity thresholds were based on tests run at QCA with newer chipsets. This patch brings back the values from the old ANI implementation for old chipsets, and it also disables weak signal detection on an earlier noise immunity level, to improve overall radio stability on affected devices.

2014-03-03ath9k_hw: toggle weak signal detection in AP mode on older chipsetsFelix Fietkau1-8/+10
The commit 80b4205b "ath9k: Fix OFDM weak signal detection for AP mode" prevented weak signal detection changes from taking effect in AP mode on all chipsets, claiming it is "not allowed". The main reason for not disabling weak signal detection in AP mode is that typically beacon RSSI is used to track whether it is needed to boost range, and this is unavailable in AP mode for obvious reasons. The problem with not disabling weak signal detection is that older chipsets are very sensitive to high PHY error counts. When faced with heavy noise, this can lead to an excessive amount of "Failed to stop TX DMA" errors in the field. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.
