+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.

+
+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.

+
+Current implementation of RT6352 support provides too high tx power

+amplifier by 6dB to match board target power of 17dBm.
+Transmited signal strength with this patch is similar to that of

+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.

+ 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 2/5] 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 1/2] rt2x00: reduce tx power to nominal level on RT6352
-Date: Thu, 27 Dec 2018 15:05:25 +0100
-Message-Id: <1545919526-4074-1-git-send-email-pozega.tomislav@gmail.com>
-X-Mailer: git-send-email 1.7.0.4
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Sender: linux-wireless-owner@vger.kernel.org
-Precedence: bulk
-List-ID: <linux-wireless.vger.kernel.org>
-X-Mailing-List: linux-wireless@vger.kernel.org
-X-Virus-Scanned: ClamAV using ClamSMTP
-
-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.
