+Subject: ARM: dts: am3517-evm: Fix misc pinmuxing
+
+From: Adam Ford <aford173@gmail.com>
+
+[ Upstream commit 942da3af32b2288e674736eb159d1fc676261691 ]
+
+The bootloader for the AM3517 has previously done much of the pin
+muxing, but as the bootloader is moving more and more to a model
+based on the device tree, it may no longer automatically mux the
+pins, so it is necessary to add the pinmuxing to the Linux device
+trees so the respective peripherals can remain functional.

+From: Mark Brown <broonie@kernel.org>
+
+[ Upstream commit 0e486fe341fabd8e583f3d601a874cd394979c45 ]
+
+The MCLK of the WM8731 on the AT91SAM9G20-EK board is connected to the
+PCK0 output of the SoC and is expected to be set to 12MHz. Previously
+this was mapped using pre-common clock API calls in the audio machine
+driver but the conversion to the common clock framework broke that so
+describe things in the DT instead.

+Subject: ARM: dts: imx6qdl-apalis: Fix sgtl5000 detection issue
+
+From: Fabio Estevam <festevam@gmail.com>
+
+[ Upstream commit fa51e1dc4b91375bc18349663a52395ad585bd3c ]
+
+On a custom carrier board with a i.MX6Q Apalis SoM, the sgtl5000 codec
+on the SoM is often not detected and the following error message is
+seen when the sgtl5000 driver tries to read the ID register:
+
+sgtl5000 1-000a: Error reading chip id -6
+
+The reason for the error is that the MCLK clock is not provided
+early enough.
+
+Fix the problem by describing the MCLK pinctrl inside the codec
+node instead of placing it inside the audmux pinctrl group.
+
+With this change applied the sgtl5000 is always detected on every boot.

+Subject: ARM: dts: logicpd-som-lv: Fix wrong pinmuxing on OMAP35
+
+From: Adam Ford <aford173@gmail.com>
+
+[ Upstream commit 46ff3df87215ff42c0cd2c4bdb7d74540384a69c ]
+
+The pinout of the OMAP35 and DM37 variants of the SOM-LV are the
+same, but the macros which define the pinmuxing are different
+between OMAP3530 and DM3730.  The pinmuxing was correct for
+for the DM3730, but wrong for the OMAP3530.  Since the boot loader
+was correctly pin-muxing the pins, this was not obvious. As the
+bootloader not guaranteed to pinmux all the pins any more, this
+causes an issue, so the pinmux needs to be moved from a common
+file to their respective board files.

+Subject: arm64: dts: meson: remove CPU opps below 1GHz for SM1 boards
+
+From: Christian Hewitt <christianshewitt@gmail.com>
+
+[ Upstream commit fd86d85401c2049f652293877c0f7e6e5afc3bbc ]
+
+Amlogic SM1 devices experience CPU stalls and random board wedges when
+the system idles and CPU cores clock down to lower opp points. Recent
+vendor kernels include a change to remove 100-250MHz and other distro
+sources also remove the 500/667MHz points. Unless all 100-667Mhz opps
+are removed or the CPU governor forced to performance stalls are still
+observed, so let's remove them to improve stability and uptime.

+
+[ Upstream commit b02d196c44ead1a5949729be9ff08fe781c3e48a ]
+
+xmit_check_hhlen() observes the dst for getting the device hard header
+length to make sure a modified packet can fit. When a helper which changes
+the dst - such as bpf_skb_set_tunnel_key() - is called as part of the
+xmit program the accessed dst is no longer valid.

+This leads to the following splat:

+From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
+
+[ Upstream commit fff8c10368e64e7f8960f149375c12ca5f3b30af ]
+
+This code is really spurious.
+It always returns an ERR_PTR, even when err is known to be 0 and calls
+put_device() after a successful device_register() call.
+
+It is likely that the return statement in the normal path is missing.
+Add 'return rdev;' to fix it.

+Subject: cifs: destage any unwritten data to the server before calling
+ copychunk_write
+
+From: Ronnie Sahlberg <lsahlber@redhat.com>
+
+[ Upstream commit f5d0f921ea362636e4a2efb7c38d1ead373a8700 ]
+
+because the copychunk_write might cover a region of the file that has not yet
+been sent to the server and thus fail.
+
+A simple way to reproduce this is:
+truncate -s 0 /mnt/testfile; strace -f -o x -ttT xfs_io -i -f -c 'pwrite 0k 128k' -c 'fcollapse 16k 24k' /mnt/testfile
+
+the issue is that the 'pwrite 0k 128k' becomes rearranged on the wire with
+the 'fcollapse 16k 24k' due to write-back caching.
+
+fcollapse is implemented in cifs.ko as a SMB2 IOCTL(COPYCHUNK_WRITE) call
+and it will fail serverside since the file is still 0b in size serverside
+until the writes have been destaged.
+To avoid this we must ensure that we destage any unwritten data to the
+server before calling COPYCHUNK_WRITE.

+
+From: Duoming Zhou <duoming@zju.edu.cn>
+
+[ Upstream commit bc6de2878429e85c1f1afaa566f7b5abb2243eef ]
+
+There is a deadlock in rr_close(), which is shown below:
+
+   (Thread 1)                |      (Thread 2)
+                             | rr_open()
+rr_close()                   |  add_timer()
+ spin_lock_irqsave() //(1)   |  (wait a time)
+ ...                         | rr_timer()
+ del_timer_sync()            |  spin_lock_irqsave() //(2)
+ (wait timer to stop)        |  ...
+
+We hold rrpriv->lock in position (1) of thread 1 and
+use del_timer_sync() to wait timer to stop, but timer handler
+also need rrpriv->lock in position (2) of thread 2.
+As a result, rr_close() will block forever.
+
+This patch extracts del_timer_sync() from the protection of
+spin_lock_irqsave(), which could let timer handler to obtain
+the needed lock.

+
+For GRE and GRETAP devices, currently o_seqno starts from 1 in native
+mode.  According to RFC 2890 2.2., "The first datagram is sent with a

+It is worth mentioning that o_seqno already starts from 0 in collect_md
+mode, see gre_fb_xmit(), where tunnel->o_seqno is passed to
+gre_build_header() before getting incremented.

+Subject: mtd: rawnand: fix ecc parameters for mt7622
+
+From: Chuanhong Guo <gch981213@gmail.com>
+
+[ Upstream commit 9fe4e0d3cbfe90152137963cc024ecb63db6e8e6 ]
+
+According to the datasheet, mt7622 only has 5 ECC capabilities instead
+of 7, and the decoding error register is arranged  as follows:
++------+---------+---------+---------+---------+
+| Bits |  19:15  |  14:10  |   9:5   |   4:0   |
++------+---------+---------+---------+---------+
+| Name | ERRNUM3 | ERRNUM2 | ERRNUM1 | ERRNUM0 |
++------+---------+---------+---------+---------+
+This means err_mask should be 0x1f instead of 0x3f and the number of
+bits shifted in mtk_ecc_get_stats should be 5 instead of 8.
+
+This commit introduces err_shift for the difference in this register
+and fix other existing parameters.
+
+Public MT7622 reference manual can be found on [0] and the info this
+commit is based on is from page 656 and page 660.

+wait_for_completion_timeout() returns unsigned long not int.

+Subject: net: bcmgenet: hide status block before TX timestamping
+
+From: Jonathan Lemon <jonathan.lemon@gmail.com>
+
+[ Upstream commit acac0541d1d65e81e599ec399d34d184d2424401 ]
+
+The hardware checksum offloading requires use of a transmit
+status block inserted before the outgoing frame data, this was
+updated in '9a9ba2a4aaaa ("net: bcmgenet: always enable status blocks")'
+
+However, skb_tx_timestamp() assumes that it is passed a raw frame
+and PTP parsing chokes on this status block.
+
+Fix this by calling __skb_pull(), which hides the TSB before calling
+skb_tx_timestamp(), so an outgoing PTP packet is parsed correctly.
+
+As the data in the skb has already been set up for DMA, and the
+dma_unmap_* calls use a separately stored address, there is no
+no effective change in the data transmission.

+Subject: net: dsa: lantiq_gswip: Don't set GSWIP_MII_CFG_RMII_CLK
+
+From: Martin Blumenstingl <martin.blumenstingl@googlemail.com>
+
+[ Upstream commit 71cffebf6358a7f5031f5b208bbdc1cb4db6e539 ]
+
+Commit 4b5923249b8fa4 ("net: dsa: lantiq_gswip: Configure all remaining
+GSWIP_MII_CFG bits") added all known bits in the GSWIP_MII_CFGp
+register. It helped bring this register into a well-defined state so the
+driver has to rely less on the bootloader to do things right.
+Unfortunately it also sets the GSWIP_MII_CFG_RMII_CLK bit without any
+possibility to configure it. Upon further testing it turns out that all
+boards which are supported by the GSWIP driver in OpenWrt which use an
+RMII PHY have a dedicated oscillator on the board which provides the
+50MHz RMII reference clock.
+
+Don't set the GSWIP_MII_CFG_RMII_CLK bit (but keep the code which always
+clears it) to fix support for the Fritz!Box 7362 SL in OpenWrt. This is
+a board with two Atheros AR8030 RMII PHYs. With the "RMII clock" bit set
+the MAC also generates the RMII reference clock whose signal then
+conflicts with the signal from the oscillator on the board. This results
+in a constant cycle of the PHY detecting link up/down (and as a result
+of that: the two ports using the AR8030 PHYs are not working).
+
+At the time of writing this patch there's no known board where the MAC
+(GSWIP) has to generate the RMII reference clock. If needed this can be
+implemented in future by providing a device-tree flag so the
+GSWIP_MII_CFG_RMII_CLK bit can be toggled per port.

+Subject: net/smc: sync err code when tcp connection was refused
+
+From: liuyacan <liuyacan@corp.netease.com>
+
+[ Upstream commit 4e2e65e2e56c6ceb4ea1719360080c0af083229e ]
+
+In the current implementation, when TCP initiates a connection
+to an unavailable [ip,port], ECONNREFUSED will be stored in the
+TCP socket, but SMC will not. However, some apps (like curl) use
+getsockopt(,,SO_ERROR,,) to get the error information, which makes
+them miss the error message and behave strangely.

+
+From: Miaoqian Lin <linmq006@gmail.com>
+
+[ Upstream commit d644e0d79829b1b9a14beedbdb0dc1256fc3677d ]
+
+The pm_runtime_enable will increase power disable depth.
+If the probe fails, we should use pm_runtime_disable() to balance
+pm_runtime_enable(). And use pm_runtime_dont_use_autosuspend() to
+undo pm_runtime_use_autosuspend()
+In the PM Runtime docs:
+    Drivers in ->remove() callback should undo the runtime PM changes done
+    in ->probe(). Usually this means calling pm_runtime_disable(),
+    pm_runtime_dont_use_autosuspend() etc.
+
+We should do this in error handling.

+Subject: sctp: check asoc strreset_chunk in sctp_generate_reconf_event
+
+From: Xin Long <lucien.xin@gmail.com>
+
+[ Upstream commit 165e3e17fe8fe6a8aab319bc6e631a2e23b9a857 ]
+
+A null pointer reference issue can be triggered when the response of a
+stream reconf request arrives after the timer is triggered, such as:
+
+  send Incoming SSN Reset Request --->
+  CPU0:
+   reconf timer is triggered,
+   go to the handler code before hold sk lock
+                            <--- reply with Outgoing SSN Reset Request
+  CPU1:
+   process Outgoing SSN Reset Request,
+   and set asoc->strreset_chunk to NULL
+  CPU0:
+   continue the handler code, hold sk lock,
+   and try to hold asoc->strreset_chunk, crash!
+
+In Ying Xu's testing, the call trace is:
+
+  [ ] BUG: kernel NULL pointer dereference, address: 0000000000000010
+  [ ] RIP: 0010:sctp_chunk_hold+0xe/0x40 [sctp]
+  [ ] Call Trace:
+  [ ]  <IRQ>
+  [ ]  sctp_sf_send_reconf+0x2c/0x100 [sctp]
+  [ ]  sctp_do_sm+0xa4/0x220 [sctp]
+  [ ]  sctp_generate_reconf_event+0xbd/0xe0 [sctp]
+  [ ]  call_timer_fn+0x26/0x130
+
+This patch is to fix it by returning from the timer handler if asoc
+strreset_chunk is already set to NULL.

+Subject: tcp: ensure to use the most recently sent skb when filling the rate
+ sample
+
+From: Pengcheng Yang <yangpc@wangsu.com>
+
+[ Upstream commit b253a0680ceadc5d7b4acca7aa2d870326cad8ad ]
+
+If an ACK (s)acks multiple skbs, we favor the information
+from the most recently sent skb by choosing the skb with
+the highest prior_delivered count. But in the interval
+between receiving ACKs, we send multiple skbs with the same
+prior_delivered, because the tp->delivered only changes
+when we receive an ACK.
+
+We used RACK's solution, copying tcp_rack_sent_after() as
+tcp_skb_sent_after() helper to determine "which packet was
+sent last?". Later, we will use tcp_skb_sent_after() instead
+in RACK.

+Subject: tcp: fix potential xmit stalls caused by TCP_NOTSENT_LOWAT
+
+From: Eric Dumazet <edumazet@google.com>
+
+[ Upstream commit 4bfe744ff1644fbc0a991a2677dc874475dd6776 ]
+
+I had this bug sitting for too long in my pile, it is time to fix it.
+
+Thanks to Doug Porter for reminding me of it!
+
+We had various attempts in the past, including commit
+0cbe6a8f089e ("tcp: remove SOCK_QUEUE_SHRUNK"),
+but the issue is that TCP stack currently only generates
+EPOLLOUT from input path, when tp->snd_una has advanced
+and skb(s) cleaned from rtx queue.
+
+If a flow has a big RTT, and/or receives SACKs, it is possible
+that the notsent part (tp->write_seq - tp->snd_nxt) reaches 0
+and no more data can be sent until tp->snd_una finally advances.
+
+What is needed is to also check if POLLOUT needs to be generated
+whenever tp->snd_nxt is advanced, from output path.
+
+This bug triggers more often after an idle period, as
+we do not receive ACK for at least one RTT. tcp_notsent_lowat
+could be a fraction of what CWND and pacing rate would allow to
+send during this RTT.
+
+In a followup patch, I will remove the bogus call
+to tcp_chrono_stop(sk, TCP_CHRONO_SNDBUF_LIMITED)
+from tcp_check_space(). Fact that we have decided to generate
+an EPOLLOUT does not mean the application has immediately
+refilled the transmit queue. This optimistic call
+might have been the reason the bug seemed not too serious.
+
+Tested:
+
+200 ms rtt, 1% packet loss, 32 MB tcp_rmem[2] and tcp_wmem[2]
+
+$ echo 500000 >/proc/sys/net/ipv4/tcp_notsent_lowat
+$ cat bench_rr.sh
+SUM=0

+
+In tcp_create_openreq_child we adjust tcp_header_len for md5 using the
+remote address in newsk. But that address is still 0 in newsk at this

+Use the address from the request socket instead.

+Subject: tls: Skip tls_append_frag on zero copy size
+
+From: Maxim Mikityanskiy <maximmi@nvidia.com>
+
+[ Upstream commit a0df71948e9548de819a6f1da68f5f1742258a52 ]
+
+Calling tls_append_frag when max_open_record_len == record->len might
+add an empty fragment to the TLS record if the call happens to be on the
+page boundary. Normally tls_append_frag coalesces the zero-sized
+fragment to the previous one, but not if it's on page boundary.
+
+If a resync happens then, the mlx5 driver posts dump WQEs in
+tx_post_resync_dump, and the empty fragment may become a data segment
+with byte_count == 0, which will confuse the NIC and lead to a CQE
+error.
+
+This commit fixes the described issue by skipping tls_append_frag on
+zero size to avoid adding empty fragments. The fix is not in the driver,
+because an empty fragment is hardly the desired behavior.

+Subject: USB: Fix xhci event ring dequeue pointer ERDP update issue
+
+From: Weitao Wang <WeitaoWang-oc@zhaoxin.com>
+
+[ Upstream commit e91ac20889d1a26d077cc511365cd7ff4346a6f3 ]
+
+In some situations software handles TRB events slower than adding TRBs.
+If the number of TRB events to be processed in a given interrupt is exactly
+the same as the event ring size 256, then the local variable
+"event_ring_deq" that holds the initial dequeue position is equal to
+software_dequeue after handling all 256 interrupts.
+
+It will cause driver to not update ERDP to hardware,
+
+Software dequeue pointer is out of sync with ERDP on interrupt exit.
+On the next interrupt, the event ring may full but driver will not
+update ERDP as software_dequeue is equal to ERDP.

+Subject: x86: __memcpy_flushcache: fix wrong alignment if size > 2^32
+
+From: Mikulas Patocka <mpatocka@redhat.com>
+
+[ Upstream commit a6823e4e360fe975bd3da4ab156df7c74c8b07f3 ]
+
+The first "if" condition in __memcpy_flushcache is supposed to align the
+"dest" variable to 8 bytes and copy data up to this alignment.  However,
+this condition may misbehave if "size" is greater than 4GiB.
+
+The statement min_t(unsigned, size, ALIGN(dest, 8) - dest); casts both
+arguments to unsigned int and selects the smaller one.  However, the
+cast truncates high bits in "size" and it results in misbehavior.
+
+For example:
+
+       suppose that size == 0x100000001, dest == 0x200000002
+       min_t(unsigned, size, ALIGN(dest, 8) - dest) == min_t(0x1, 0xe) == 0x1;
+       ...
+       dest += 0x1;
+
+so we copy just one byte "and" dest remains unaligned.
+
+This patch fixes the bug by replacing unsigned with size_t.
