2019-06-27wil6210: Add support for setting RBUFCAP configurationAlexei Avshalom Lazar4-22/+88
RBUFCAP support added in FW. The RBUFCAP feature is amendment to the block ack mechanism to prevent overloading of the recipient’s memory space, which may happen in case the link speed is higher than STA’s capability to process or consume incoming data. The block ack policy (ba_policy) is now controlled by FW so driver should ignore this field. Add new debugfs "rbufcap" to configure RBUFCAP.

2019-06-27wil6210: increase the frequency of status ring hw tail updateAhmad Masri1-3/+13
The driver updates Tx status ring HW tail only after it finishes processing the whole status ring, while the HW is still transmitting from other transmit rings. This can cause back-pressure on HW if no status entries are available. Update HW tail of Tx status ring without waiting for the end of the processing to help feeding back the HW with status entries and to allow additional packet transmission.

2019-06-27wil6210: enlarge Tx status ring sizeAhmad Masri1-1/+1
With multiple clients and in high throughput scenarios, Tx status ring can get full and become a bottleneck in Tx transmission. Set the default Tx status ring size order to 13, previous value was 12. This will double the status ring size from 4K entries to 8K entries.

2019-06-27carl9170: remove dead branch in op_conf_tx callbackChristian Lamparter1-7/+2
This patch removes the error branch for (queue > ar->hw->queues). It is no longer needed anymore as the "queue" value is validated by cfg80211's parse_txq_params() before the driver code gets called. Some background: In the old days (linux 2.6 and early 3.x), the parse_txq_params() function did not verify the "queue" value. That's why these drivers had to do it.

2019-06-27carl9170: fix misuse of device driver APIChristian Lamparter1-22/+17
This patch follows Alan Stern's recent patch: "p54: Fix race between disconnect and firmware loading" that overhauled carl9170 buggy firmware loading and driver unbinding procedures. Since the carl9170 code was adapted from p54 it uses the same functions and is likely to have the same problem, but it's just that the syzbot hasn't reproduce them (yet). a summary from the changes (copied from the p54 patch): * Call usb_driver_release_interface() rather than device_release_driver(). * Lock udev (the interface's parent) before unbinding the driver instead of locking udev->parent. * During the firmware loading process, take a reference to the USB interface instead of the USB device. * Don't take an unnecessary reference to the device during probe (and then don't drop it during disconnect). and * Make sure to prevent use-after-free bugs by explicitly setting the driver context to NULL after signaling the completion.

2019-06-27ath9k: correctly handle short radar pulsesZefir Kurtisi1-1/+5
In commit 3c0efb745a17 ("ath9k: discard undersized packets") the lower bound of RX packets was set to 10 (min ACK size) to filter those that would otherwise be treated as invalid at mac80211. Alas, short radar pulses are reported as PHY_ERROR frames with length set to 3. Therefore their detection stopped working after that commit. NOTE: ath9k drivers built thereafter will not pass DFS certification. This extends the criteria for short packets to explicitly handle PHY_ERROR frames.

2019-06-27mwifiex: don't disable hardirqs; just softirqsBrian Norris18-378/+256
main_proc_lock and int_lock (in mwifiex_adapter) are the only spinlocks used in hardirq contexts. The rest are only in task or softirq contexts. Convert every other lock from *_irq{save,restore}() variants to _bh() variants. This is a mechanical transformation of all spinlock usage in mwifiex using the following: Step 1: I ran this nasty sed script: sed -i -E '/spin_lock_irqsave|spin_unlock_irqrestore/ { /main_proc_lock|int_lock/! { s:(spin_(un|)lock)_irq(save|restore):\1_bh: ; # Join broken lines. :a /;$/! { N; s/\s*\n\s*//; ba } /,.*\);$/ s:,.*\):\): } }' drivers/net/wireless/marvell/mwifiex/* Step 2: Manually delete the flags / ra_list_flags args from: mwifiex_send_single_packet() mwifiex_11n_aggregate_pkt() mwifiex_send_processed_packet() which are now unused. Step 3: Apply this semantic patch (coccinelle) to remove the unused 'flags' variables: // <smpl> @@ type T; identifier i; @@ ( extern T i; | - T i; ... when != i ) // </smpl> (Usage is something like this: make coccicheck COCCI=./patch.cocci MODE=patch M=drivers/net/wireless/marvell/mwifiex/ although this skips *.h files for some reasons, so I had to massage stuff.) Testing: I've played with a variety of stress tests, including download stress tests on the same APs which caught regressions with commit 5188d5453bc9 ("mwifiex: restructure rx_reorder_tbl_lock usage"). I've primarily tested on Marvell 8997 / PCIe, although I've given 8897 / SDIO a quick spin as well.

2019-06-27mwifiex: dispatch/rotate from reorder table atomicallyBrian Norris1-19/+24
mwifiex_11n_scan_and_dispatch() and mwifiex_11n_dispatch_pkt_until_start_win() share similar patterns, where they perform a few different actions on the same table, using the same lock, but non-atomically. There have been other attempts to clean up this sort of behavior, but they have had problems (incomplete; introducing new deadlocks). We can improve these functions' atomicity by queueing up our RX packets in a list, to dispatch at the end of the function. This avoids problems of another operation modifying the table in between our dispatch and rotation operations. This was inspired by investigations around this: http://lkml.kernel.org/linux-wireless/20181130175957.167031-1-briannorris@chromium.org Subject: [4.20 PATCH] Revert "mwifiex: restructure rx_reorder_tbl_lock usage" While the original (now-reverted) patch had good intentions in restructuring some of the locking patterns in this driver, it missed an important detail: we cannot defer to softirq contexts while already in an atomic context. We can help avoid this sort of problem by separating the two steps of: (1) iterating / clearing the mwifiex reordering table (2) dispatching received packets to upper layers This makes it much harder to make lock recursion mistakes, as these two steps no longer need to hold the same locks.

2019-06-27mt76: mt7603: rework and fix tx status reportingFelix Fietkau4-41/+108
Tx status reporting on mt7603 has a number of issues: - the hardware can alter the first rate index, but it is not reported to the driver - probing is very imprecise, because it alters the per-client rate set, but only considers info->status.rates for rate selection of a single probe packet - short/long GI selection has limitations, which are not accurately reported to mac80211 - if rates are changed while packets are in flight, tx status reports for the old rate set might be processed based on the new selection This led to very suboptimal rate selection with minstrel_ht. This patch completely reworks tx status reporting to get rid of these limitations: - Store the previous and current rate set in the driver + the TSF value at the time of the switch. - Use the tx status TSF value to determine which rate set needs to be used as reference. - Report only short or long GI rates for a single status event, not a mix. - The hardware reports the last used rate index. Use it along with the retry count to figure out what rate was used for the first attempt. - Use the same retry count value for all rate slots to make this calculation work. - Derive the probe rate from the current rateset instead of the skb cb - Do not wait for a status report for the probe frame before removing the probe rate from the rate table. Do it immediately after it was referenced in a tx status report. - Use the first half of the first rate retry budget for the probe rate in order to avoid using too many retries on that rate With this patch, throughput under bad link conditions is improved significantly, and there is a lot less rate fluctuation going on.
