Subject: [PATCH 01/28] rt2x00: use simple_read_from_buffer()
The problem with this copy_to_user() calls is that they don't ensure
that "size" is less than the "length" which the user provided.
Obviously, this is debugfs and "size" is normally going to be very small
so it probably doesn't matter, but this is the correct thing to do.

Subject: [PATCH 03/28] rt2800mmio: use txdone/txstatus routines from lib
Use usb txdone/txstatus routines (now in rt2800libc) for mmio devices.
Note this also change how we handle INT_SOURCE_CSR_TX_FIFO_STATUS
interrupt. Now it is disabled since IRQ routine till end of the txstatus
tasklet (the same behaviour like others interrupts). Reason to do not
disable this interrupt was not to miss any tx status from 16 entries
FIFO register. Now, since we check for tx status timeout, we can
allow to miss some tx statuses. However this will be improved in further
patch where I also implement read status FIFO register in the tasklet.

Subject: [PATCH 05/28] rt2x00: use different txstatus timeouts when flushing
Use different tx status timeouts for normal operation and when flushing.
This increase timeout to 2s for normal operation as when there are bad
radio conditions and frames are reposted many times device can not provide
the status for quite long. With new timeout we can still get valid status
on such bad conditions.

Content-Transfer-Encoding: 8bit
Current implementation of RT6352 support provides too high tx power
at least on iPA/eLNA devices. Reduce amplification of variable gain
amplifier by 6dB to match board target power of 17dBm.
Transmited signal strength with this patch is similar to that of
stock firmware or pandorabox firmware. Throughput measured with iperf
improves. Device tested: Xiaomi Miwifi Mini.

Subject: [PATCH 13/28] rt2x00: Work around a firmware bug with shared keys
Apparently the rt2x61 firmware fails temporarily to decode
broadcast packets if the shared keys are not assigned
in the "correct" sequence. At the same time unicast
packets work fine, since they are encrypted with the
pairwise key.
At least with WPA2 CCMP mode the shared keys are
set in the following sequence: keyidx=1, 2, 1, 2.
After a while only keyidx 2 gets decrypted, and
keyidx 1 is ignored, probably because there is never
a keyidx 3.
Symptoms are arping -b works for 10 minutes, since
keyidx=2 is used for broadcast, and then it stops
working for 10 minutes, because keyidx=1 is used.
That failure mode repeats forever.
Note, the firmware does not even know which keyidx
corresponds to which hw_key_idx so the firmware is
trying to be smarter than the driver, which is bound
to fail.
As workaround the function rt61pci_config_shared_key
requests software decryption of the shared keys,
by returning EOPNOTSUPP. However, pairwise keys are
still handled by hardware which works just fine.

As reported by Randy we can overwhelm logs on some USB error conditions.
To avoid that use dev_warn_ratelimited() and dev_err_ratelimitd().

Some USB host devices/drivers on some conditions can always return
EPROTO error on submitted URBs. That can cause infinity loop in the
rt2x00 driver.
Since we can have single EPROTO errors we can not mark as device as
removed to avoid infinity loop. However we can count consecutive
EPROTO errors and mark device as removed if get lot of it.
I choose number 10 as threshold.

Subject: [PATCH v3 4/4] rt2x00: do not print error when queue is full
Date: Tue, 12 Mar 2019 10:51:43 +0100

For unknown reasons printk() on some context can cause CPU hung on
embedded MT7620 AP/router MIPS platforms. What can result on wifi
disconnects.
This patch move queue full messages to debug level what is consistent
with other mac80211 drivers which drop packet silently if tx queue is
full. This make MT7620 OpenWRT routers more stable, what was reported
by various users.

Subject: [PATCH 21/28] rt2800: partially restore old mmio txstatus behaviour
Do not disable txstatus interrupt and add quota of processed tx statuses in
one tasklet. Quota is needed to allow to fed device with new frames during
processing of tx statuses.
Patch fixes about 15% performance degradation on some scenarios coused by
0b0d556e0ebb ("rt2800mmio: use txdone/txstatus routines from lib").

timeouts
Sometimes we can get into situation when there are pending statuses,
but we do not get INT_SOURCE_CSR_TX_FIFO_STATUS. Handle this situation
by arming timeout timer and read statuses (it will fix case when
we just do not have irq) and queue work to handle case we missed
statues from hardware FIFO.

Subject: [PATCH 02/15] rt2800: add helpers for reading dma done index
For mmio we do not properlly trace dma done Q_INDEX_DMA_DONE index
for TX queues. That would require implementing INT_SOURCE_CSR_*_DMA_DONE
interrupts, what is rather not worth to do due to adding extra
CPU load (small but still somewhat not necessary otherwise).
We can just read TX DMA done indexes from registers directly. What
will be used by watchdog.

Subject: [PATCH 03/15] rt2800: initial watchdog implementation
Add watchdog for rt2800 devices. For now it only detect hung
and print error.
[Note: I verified that printing messages from process context is
fine on MT7620 (WT3020) platform that have problem when printk
is called from interrupt context].

Subject: [PATCH 07/15] rt2800: do not enable watchdog by default
Make watchdog disabled by default and add module parameter to enable it.
User will have to create file in /etc/modprobe.d/ with
options rt2800lib watchdog=1
to enable the watchdog or load "rt2800lib watchdog=1" module manually
before loading rt2800{soc,pci,usb} module.

Date: Mon, 1 Jul 2019 12:53:13 +0200
Subject: [PATCH 08/15] rt2x00usb: fix rx queue hang
Since commit ed194d136769 ("usb: core: remove local_irq_save() around
->complete() handler") the handler rt2x00usb_interrupt_rxdone() is
not running with interrupts disabled anymore. So this completion handler
is not guaranteed to run completely before workqueue processing starts
for the same queue entry.
Be sure to set all other flags in the entry correctly before marking
this entry ready for workqueue processing. This way we cannot miss error
conditions that need to be signalled from the completion handler to the
worker thread.
Note that rt2x00usb_work_rxdone() processes all available entries, not
only such for which queue_work() was called.
This patch is similar to what commit df71c9cfceea ("rt2x00: fix order
of entry flags modification") did for TX processing.
This fixes a regression on a RT5370 based wifi stick in AP mode, which
suddenly stopped data transmission after some period of heavy load. Also
stopping the hanging hostapd resulted in the error message "ieee80211
phy0: rt2x00queue_flush_queue: Warning - Queue 14 failed to flush".
Other operation modes are probably affected as well, this just was
the used testcase.
Fixes: ed194d136769 ("usb: core: remove local_irq_save() around ->complete() handler")

Subject: [PATCH 09/15] rt2x00usb: remove unnecessary rx flag checks
In contrast to the TX path, there is no need to separately read the transfer
status from the device after receiving RX data. Consequently, there is no
real STATUS_PENDING RX processing queue entry state.
Remove the unnecessary ENTRY_DATA_STATUS_PENDING flag checks from the RX path.
Also remove the misleading comment about reading RX status from device.

Subject: [PATCH 10/15] rt2x00: no need to check return value of debugfs_create
functions
When calling debugfs functions, there is no need to ever check the
return value. The function can work or not, but the code logic should
never do something different based on this.
Because we don't need to save the individual debugfs files and
directories, remove the local storage of them and just remove the entire
debugfs directory in a single call, making things a lot simpler.

Subject: [PATCH 12/15] rt2x00: clear IV's on start to fix AP mode regression
To do not brake HW restart we should keep initialization vectors data.
I assumed that on start the data is already initialized to zeros, but
that not true on some scenarios and we should clear it. So add
additional flag to check if we are under HW restart and clear IV's
data if we are not.
Patch fixes AP mode regression.

Subject: [PATCH 13/15] rt2x00: do not set IEEE80211_TX_STAT_AMPDU_NO_BACK on
tx status
According to documentation IEEE80211_TX_STAT_AMPDU_NO_BACK is suppose
to be used when we do not recive BA (BlockAck). However on rt2x00 we
use it when remote station fail to decode one or more subframes within
AMPDU (some bits are not set in BlockAck bitmap). Setting the flag result
in sent of BAR (BlockAck Request) frame and this might result of abuse
of BA session, since remote station can sent BA with incorrect
sequence numbers after receiving BAR. This problem is visible especially
when connecting two rt2800 devices.
Previously I observed some performance benefits when using the flag
when connecting with iwlwifi devices. But currently possibly due
to reacent changes in rt2x00 removing the flag has no effect on
those test cases.
So remove the IEEE80211_TX_STAT_AMPDU_NO_BACK.

Subject: [PATCH 14/15] rt2x00: clear up IV's on key removal
After looking at code I realized that my previous fix
95844124385e ("rt2x00: clear IV's on start to fix AP mode regression")
was incomplete. We can still have wrong IV's after re-keyring.
To fix that, clear up IV's also on key removal.

Subject: [PATCH 15/15] Revert "rt2800: enable TX_PIN_CFG_LNA_PE_ bits per
band"
This reverts commit 9ad3b55654455258a9463384edb40077439d879f.
As reported by Sergey:
"I got some problem after upgrade kernel to 5.2 version (debian testing
linux-image-5.2.0-2-amd64). 5Ghz client stopped to see AP.
Some tests with 1metre distance between client-AP: 2.4Ghz -22dBm, for
5Ghz - 53dBm !, for longer distance (8m + walls) 2.4 - 61dBm, 5Ghz not
visible."
It was identified that rx signal level degradation was caused by
9ad3b5565445 ("rt2800: enable TX_PIN_CFG_LNA_PE_ bits per band").
So revert this commit.

Hence remove errornous line 5281 to make the driver actually
execute the correct initialization routine for MT7620 chips.
As it was requested by Stanislaw Gruszka remove setting values of
MIMO_PS_CFG and TX_PIN_CFG. MIMO_PS_CFG is responsible for MIMO
power-safe mode (which is disabled), hence we can drop setting it.
TX_PIN_CFG is set correctly in other functions, and as setting this
value breaks some devices, rather don't set it here during init, but
only modify it later on.

Subject: [PATCH] rt2x00: add throughput LED trigger
This adds a (currently missing) throughput LED trigger for the rt2x00
driver. Previously, LED triggers had to be assigned to the netdev, which
was limited to a single VAP.
