+'end_sector' is compared to 'rdev->recovery_offset', which is offset to

+Subject: misc: fastrpc: reject new invocations during device removal
+
+From: Richard Acayan <mailingradian@gmail.com>
+
+commit 46248400d81e2aa0b65cd659d6f40188192a58b6 upstream.
+
+The channel's rpmsg object allows new invocations to be made. After old
+invocations are already interrupted, the driver shouldn't try to invoke
+anymore. Invalidating the rpmsg at the end of the driver removal
+function makes it easy to cause a race condition in userspace. Even
+closing a file descriptor before the driver finishes its cleanup can
+cause an invocation via fastrpc_release_current_dsp_process() and
+subsequent timeout.
+
+Invalidate the channel before the invocations are interrupted to make
+sure that no invocations can be created to hang after the device closes.

+
+From: Richard Acayan <mailingradian@gmail.com>
+
+commit b6a062853ddf6b4f653af2d8b75ba45bb9a036ad upstream.
+
+The return value is initialized as -1, or -EPERM. The completion of an
+invocation implies that the return value is set appropriately, but
+"Permission denied" does not accurately describe the outcome of the
+invocation. Set the invocation's return value to a more appropriate
+"Broken pipe", as the cleanup breaks the driver's connection with rpmsg.

+Subject: usb: cdns3: fix NCM gadget RX speed 20x slow than expection at iMX8QM
+
+From: Frank Li <Frank.Li@nxp.com>
+
+commit dbe678f6192f27879ac9ff6bc7a1036aad85aae9 upstream.
+
+At iMX8QM platform, enable NCM gadget and run 'iperf3 -s'.
+At host, run 'iperf3 -V -c fe80::6863:98ff:feef:3e0%enxc6e147509498'
+
+[ 5] 0.00-1.00 sec 1.55 MBytes 13.0 Mbits/sec 90 4.18 KBytes
+[ 5] 1.00-2.00 sec 1.44 MBytes 12.0 Mbits/sec 75 4.18 KBytes
+[ 5] 2.00-3.00 sec 1.48 MBytes 12.4 Mbits/sec 75 4.18 KBytes
+
+Expected speed should be bigger than 300Mbits/sec.
+
+The root cause of this performance drop was found to be data corruption
+happening at 4K borders in some Ethernet packets, leading to TCP
+checksum errors. This corruption occurs from the position
+(4K - (address & 0x7F)) to 4K. The u_ether function's allocation of
+skb_buff reserves 64B, meaning all RX addresses resemble 0xXXXX0040.
+
+Force trb_burst_size to 16 can fix this problem.

+Subject: usb: gadget: f_fs: Add unbind event before functionfs_unbind
+
+From: Uttkarsh Aggarwal <quic_uaggarwa@quicinc.com>
+
+commit efb6b535207395a5c7317993602e2503ca8cb4b3 upstream.
+
+While exercising the unbind path, with the current implementation
+the functionfs_unbind would be calling which waits for the ffs->mutex
+to be available, however within the same time ffs_ep0_read is invoked
+& if no setup packets are pending, it will invoke function
+wait_event_interruptible_exclusive_locked_irq which by definition waits
+for the ev.count to be increased inside the same mutex for which
+functionfs_unbind is waiting.
+This creates deadlock situation because the functionfs_unbind won't
+get the lock until ev.count is increased which can only happen if
+the caller ffs_func_unbind can proceed further.
+
+Following is the illustration:
+
+ CPU1 CPU2
+
+ffs_func_unbind() ffs_ep0_read()
+ mutex_lock(ffs->mutex)
+ wait_event(ffs->ev.count)
+functionfs_unbind()
+ mutex_lock(ffs->mutex)
+ mutex_unlock(ffs->mutex)
+
+ffs_event_add()
+
+<deadlock>
+
+Fix this by moving the event unbind before functionfs_unbind
+to ensure the ev.count is incrased properly.
