* tcp: fix splice() and tcp collapsing interactionEric Dumazet2013-01-101-3/+10
| | | | | | | | | | | | | | | | | | | | | | | Under unusual circumstances, TCP collapse can split a big GRO TCP packet while its being used in a splice(socket->pipe) operation. skb_splice_bits() releases the socket lock before calling splice_to_pipe().

| * b43: Fix firmware loading when driver is built into the kernelLarry Finger2013-01-073-16/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent versions of udev cause synchronous firmware loading from the probe routine to fail because the request to user space would time out. The original fix for b43 (commit 6b6fa58) moved the firmware load from the probe routine to a work queue, but it still used synchronous firmware loading. This method is OK when b43 is built as a module; however, it fails when the driver is compiled into the kernel. This version changes the code to load the initial firmware file using request_firmware_nowait(). A completion event is used to hold the work queue until that file is available. This driver reads several firmware files - the remainder can be read synchronously. On some test systems, the async read fails; however, a following synch read works, thus the async failure falls through to the sync try.

| * wireless: add new wil6210 802.11ad 60GHz driverVladimir Kondratiev2013-01-0417-0/+6203
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for the 60 GHz 802.11ad Wilocity card through a new driver, wil6210. Wilocity implemented the firmware, QCA maintains the device driver. Currently supported: - STA: with security - AP: limited to 1 connected STA, security disabled - Monitor: due to a hardware/firmware limitation either control or non-control frames are monitored Using a STA and AP with this drive, one can assemble a fully functional BSS. Throughput of 1.2Gbps is achieved with iperf. The wil6210 cards have on-board flash memory for the firmware, the cards comes pre-flashed and no firmware download is required.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | wait_event_interruptible function returns -ERESTARTSYS if it's interrupted by a signal. Driver should check the return value and handle this case properly. In mwifiex_wait_queue_complete() routine, as we are now checking wait_event_interruptible return value, the condition check is not required. Also, we have removed mwifiex_cancel_pending_ioctl() call to avoid a chance of sending second command to FW by other path as soon as we clear current command node. FW can not handle two commands simultaneously.

Since the mac80211 stores its data in ieee80211_bss which is embedded into cfg80211_bss, mac80211's data will be duplicated too. This becomes a problem when a driver needs the dtim_period since this data exists only in the beacon's instance in cfg80211 bss table which isn't the instance that is used when associating. Remove the DTIM period from the BSS table and track it explicitly to avoid this problem.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a very old bug, but there's nothing that prevents the timer from running while the module is being removed when we only do del_timer() instead of del_timer_sync(). The timer should normally not be running at this point, but it's not clearly impossible (or we could just remove this.)

To fix this problem remove the per-station work struct, maintain a station cleanup list instead and flush this list when stations are flushed. To keep this patch smaller for stable, do this when the stations are flushed (sta_info_flush()). This unfortunately brings back the original roaming delay; I'll fix that again in a separate patch. Also, Ben reported that the original commit could sometimes (with many interfaces) cause long delays when an interface is set down, due to blocking on flush_workqueue(). Since we now maintain the cleanup list, this particular change of the original patch can be reverted.

The condition used to set the flag in pipe_to_sendpage() relied on splice() user passing the exact number of bytes present in the pipe, or a smaller one. But some programs pass an arbitrary high value, and the test fails. The effect of this bug is a lack of tcp_push() at the end of a splice(pipe -> socket) call, and possibly very slow or erratic TCP sessions. We should both test sd->total_len and fact that another fragment is in the pipe (pipe->nrbufs > 1) Many thanks to Willy for providing very clear bug report, bisection and test programs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ath9k consists of 2 different sub-modules: ATH9K and ATH9K_HTC. Both uses common Atheros code from ath.ko and need ATH_COMMON. However, while ATH9K selects ATH_COMMON, ATH9K_HTC does not. As result, if ATH9K_HTC is the only Atheros card selected, compilation fails with unresolved symbols. This patch moves ATH_COMMON selection to the common part for both ATH9K and ATH9K_HTC Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W.
