2012-12-12solos-pci: fix double-free of TX skb in DMA modeDavid Woodhouse
We weren't clearing card->tx_skb[port] when processing the TX done interrupt. If there wasn't another skb ready to transmit immediately, this led to a double-free because we'd free it *again* next time we did have a packet to send.

2012-12-11bna: Firmware updateRasesh Mody
Change Details: - Added Stats clear counter to the bfi_enet_stats_mac structure and ethtool stats - Modified the firmware naming convention to contain the firmware image version (3.1.0.0). The new convention is <firmware-image>-<firmware-version>.bin The change will enforce loading only compatible firmware with this driver and also avoid over-writing the old firmware image in-order to load new version driver as the firmware names used to be the same.

2012-12-11bna: Add RX StateRasesh Mody
Change Details: - BNA state machine for Rx in start_wait state moves it to stop_wait on receipt of RX_E_STOP. In Rx stop_wait state, on receipt of RX_E_STARTED event does enet stop RX_E_STOPPED event does rx_cleanup_cbfn rx_cleanup_cbfn in this case is called without post_cbfn. post_cbfn happens only after RX_E_STARTED event is received in start_wait. Without doing post_cbfn, NAPI remains disabled and in cleanup we try to disable again causing endless wait. ifconfig process and other workers can thus get stuck. - Introducing start_stop_wait state for Rx. This state handles the case of if post_cbfn is not done simply do stop without the cleanup. Signed-off-by: Rasesh Mody <rmody@brocade.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Due to my recent commit (ath9k: allow to load EEPROM content via firmware API) smatch complains about that the 'pdata' variable in 'ath9k_hw_init' can be NULL and it is dereferenced before checking that.

In case of rehashing, introduce a global variable 'br_mdb_rehash_seq' which gets increased every time when rehashing, and assign net->dev_base_seq + br_mdb_rehash_seq to cb->seq. In theory cb->seq could be wrapped to zero, but this is not easy to fix, as net->dev_base_seq is not visible inside br_mdb_rehash(). In practice, this is rare.

2012-12-11net: fix a race in gro_cell_poll()Eric Dumazet
Dmitry Kravkov reported packet drops for GRE packets since GRO support was added. There is a race in gro_cell_poll() because we call napi_complete() without any synchronization with a concurrent gro_cells_receive() Once bug was triggered, we queued packets but did not schedule NAPI poll. We can fix this issue using the spinlock protected the napi_skbs queue, as we have to hold it to perform skb dequeue anyway. As we open-code skb_dequeue(), we no longer need to mask IRQS, as both producer and consumer run under BH context.

2012-12-10iwlwifi: don't handle masked interruptEmmanuel Grumbach
This can lead to a panic if the driver isn't ready to handle them. Since our interrupt line is shared, we can get an interrupt at any time (and CONFIG_DEBUG_SHIRQ checks that even when the interrupt is being freed). If the op_mode has gone away, we musn't call it. To avoid this the transport disables the interrupts when the hw is stopped and the op_mode is leaving. If there is an event that would cause an interrupt the INTA register is updated regardless of the enablement of the interrupts: even if the interrupts are disabled, the INTA will be changed, but the device won't issue an interrupt. But the ISR can be called at any time, so we ought ignore the value in the INTA otherwise we can call the op_mode after it was freed. I found this bug when the op_mode_start failed, and called iwl_trans_stop_hw(trans, true). Then I played with the RFKILL button, and removed the module. While removing the module, the IRQ is freed, and the ISR is called (CONFIG_DEBUG_SHIRQ enabled). Panic.

We know that we have issues with the fw in the reclaim path. This is why iwl_reclaim doesn't complain too loud when it happens since it is recoverable. Somehow, the caller of iwl_reclaim however WARNed when it happens. This doesn't make any sense. When I digged into the history of that code, I discovered that this bug occurs only when we receive a BA notification. So move the W/A in the BA notification handling code where it was before.

The calibration data for devices w/o a separate EEPROM chip can be specified via the 'eeprom_data' field of 'ath9k_platform_data'. The 'eeprom_data' is usually filled from board specific setup functions. It is easy if the EEPROM data is mapped to the memory, but it can be complicated if it is stored elsewhere.

Almost each of its caller has a 'struct ath_hw *' parameter in their argument list, and that is dereferenced in order to get the 'struct ath_common' pointer. Change the first argument of 'ath9k_hw_nvram_read' to be a 'struct ath_hw *', and remove the dereference calls from the callers.

2012-12-10rt2800usb: Add support for 2001:3c1e (D-Link DWA-125 rev B1) USB Wi-Fi adapterMaia Kozheva
D-Link DWA-125/B1 is a relatively new USB Wi-Fi adapter, using a Ralink chipset supported by the rt2800usb driver. Currently, to work around the problem (it's missing in all present kernel versions, up to and including 3.7.x), I had to add this to /etc/rc.local: echo 2001 3c1e >> /sys/bus/usb/drivers/rt2800usb/new_id After that, the device works without problems. Been using it for over a week with no bugs in sight. The attached patch is trivial and simply adds the new USB ID to the list of devices handled by rt2800usb.
