+Subject: crypto: lib/mpi - Fix unexpected pointer access in mpi_ec_init
+
+From: Tianjia Zhang <tianjia.zhang@linux.alibaba.com>
+
+[ Upstream commit ba3c5574203034781ac4231acf117da917efcd2a ]
+
+When the mpi_ec_ctx structure is initialized, some fields are not
+cleared, causing a crash when referencing the field when the
+structure was released. Initially, this issue was ignored because
+memory for mpi_ec_ctx is allocated with the __GFP_ZERO flag.
+For example, this error will be triggered when calculating the
+Za value for SM2 separately.

+Subject: dma-buf: add dma_fence_timestamp helper
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Christian König <christian.koenig@amd.com>
+
+[ Upstream commit b83ce9cb4a465b8f9a3fa45561b721a9551f60e3 ]
+
+When a fence signals there is a very small race window where the timestamp
+isn't updated yet. sync_file solves this by busy waiting for the
+timestamp to appear, but on other ocassions didn't handled this
+correctly.
+
+Provide a dma_fence_timestamp() helper function for this and use it in
+all appropriate cases.
+
+Another alternative would be to grab the spinlock when that happens.
+
+v2 by teddy: add a wait parameter to wait for the timestamp to show up, in case
+ the accurate timestamp is needed and/or the timestamp is not based on
+ ktime (e.g. hw timestamp)
+v3 chk: drop the parameter again for unified handling

+Fbdev's deferred I/O sorts all dirty pages by default, which incurs a

+
+Most fbdev drivers with deferred I/O build a bounding rectangle around
+the dirty pages or simply flush the whole screen. The only two affected
+DRM drivers, generic fbdev and vmwgfx, both use a bounding rectangle.
+In those cases, the exact order of the pages doesn't matter. The other
+drivers look at the page index or handle pages one-by-one. The patch
+sets the sort_pagelist flag for those, even though some of them would
+probably work correctly without sorting. Driver maintainers should update
+their driver accordingly.
+
+Sorting pages by memory offset for deferred I/O performs an implicit
+bubble-sort step on the list of dirty pages. The algorithm goes through
+the list of dirty pages and inserts each new page according to its
+index field. Even worse, list traversal always starts at the first
+entry. As video memory is most likely updated scanline by scanline, the
+algorithm traverses through the complete list for each updated page.
+
+For example, with 1024x768x32bpp each page covers exactly one scanline.
+Writing a single screen update from top to bottom requires updating
+768 pages. With an average list length of 384 entries, a screen update
+creates (768 * 384 =) 294912 compare operation.
+
+Fix this by making the sorting step opt-in and update the few drivers
+that require it. All other drivers work with unsorted page lists. Pages
+are appended to the list. Therefore, in the common case of writing the
+framebuffer top to bottom, pages are still sorted by offset, which may
+have a positive effect on performance.
+
+Playing a video [1] in mplayer's benchmark mode shows the difference
+(i7-4790, FullHD, simpledrm, kernel with debugging).
+
+ mplayer -benchmark -nosound -vo fbdev ./big_buck_bunny_720p_stereo.ogg
+
+With sorted page lists:
+
+ BENCHMARKs: VC: 32.960s VO: 73.068s A: 0.000s Sys: 2.413s = 108.441s
+ BENCHMARK%: VC: 30.3947% VO: 67.3802% A: 0.0000% Sys: 2.2251% = 100.0000%
+
+With unsorted page lists:
+
+ BENCHMARKs: VC: 31.005s VO: 42.889s A: 0.000s Sys: 2.256s = 76.150s
+ BENCHMARK%: VC: 40.7156% VO: 56.3219% A: 0.0000% Sys: 2.9625% = 100.0000%
+
+VC shows the overhead of video decoding, VO shows the overhead of the
+video output. Using unsorted page lists reduces the benchmark's run time
+by ~32s/~25%.

+Subject: fbdev: Fix incorrect page mapping clearance at
+ fb_deferred_io_release()
+
+From: Takashi Iwai <tiwai@suse.de>
+
+[ Upstream commit fe9ae05cfbe587dda724fcf537c00bc2f287da62 ]
+
+The recent fix for the deferred I/O by the commit
+ 3efc61d95259 ("fbdev: Fix invalid page access after closing deferred I/O devices")
+caused a regression when the same fb device is opened/closed while
+it's being used. It resulted in a frozen screen even if something
+is redrawn there after the close. The breakage is because the patch
+was made under a wrong assumption of a single open; in the current
+code, fb_deferred_io_release() cleans up the page mapping of the
+pageref list and it calls cancel_delayed_work_sync() unconditionally,
+where both are no correct behavior for multiple opens.
+
+This patch adds a refcount for the opens of the device, and applies
+the cleanup only when all files get closed.
+
+As both fb_deferred_io_open() and _close() are called always in the
+fb_info lock (mutex), it's safe to use the normal int for the
+refcounting.
+
+Also, a useless BUG_ON() is dropped.

+Subject: fbdev: Fix invalid page access after closing deferred I/O devices
+
+From: Takashi Iwai <tiwai@suse.de>
+
+[ Upstream commit 3efc61d95259956db25347e2a9562c3e54546e20 ]
+
+When a fbdev with deferred I/O is once opened and closed, the dirty
+pages still remain queued in the pageref list, and eventually later
+those may be processed in the delayed work. This may lead to a
+corruption of pages, hitting an Oops.
+
+This patch makes sure to cancel the delayed work and clean up the
+pageref list at closing the device for addressing the bug. A part of
+the cleanup code is factored out as a new helper function that is
+called from the common fb_release().

+Subject: fbdev: flush deferred IO before closing
+
+From: Nam Cao <namcao@linutronix.de>
+
+[ Upstream commit 33cd6ea9c0673517cdb06ad5c915c6f22e9615fc ]
+
+When framebuffer gets closed, the queued deferred IO gets cancelled. This
+can cause some last display data to vanish. This is problematic for users
+who send a still image to the framebuffer, then close the file: the image
+may never appear.
+
+To ensure none of display data get lost, flush the queued deferred IO
+first before closing.
+
+Another possible solution is to delete the cancel_delayed_work_sync()
+instead. The difference is that the display may appear some time after
+closing. However, the clearing of page mapping after this needs to be
+removed too, because the page mapping is used by the deferred work. It is
+not completely obvious whether it is okay to not clear the page mapping.
+For a patch intended for stable trees, go with the simple and obvious
+solution.

+Subject: fbdev: Rename pagelist to pagereflist for deferred I/O
+
+From: Thomas Zimmermann <tzimmermann@suse.de>
+
+[ Upstream commit e80eec1b871a2acb8f5c92db4c237e9ae6dd322b ]
+
+Rename various instances of pagelist to pagereflist. The list now
+stores pageref structures, so the new name is more appropriate.
+
+In their write-back helpers, several fbdev drivers refer to the
+pageref list in struct fb_deferred_io instead of using the one
+supplied as argument to the function. Convert them over to the
+supplied one. It's the same instance, so no change of behavior
+occurs.

+Subject: fbdev: Track deferred-I/O pages in pageref struct
+
+From: Thomas Zimmermann <tzimmermann@suse.de>
+
+[ Upstream commit 56c134f7f1b58be08bdb0ca8372474a4a5165f31 ]
+
+Store the per-page state for fbdev's deferred I/O in struct
+fb_deferred_io_pageref. Maintain a list of pagerefs for the pages
+that have to be written back to video memory. Update all affected
+drivers.
+
+As with pages before, fbdev acquires a pageref when an mmaped page
+of the framebuffer is being written to. It holds the pageref in a
+list of all currently written pagerefs until it flushes the written
+pages to video memory. Writeback occurs periodically. After writeback
+fbdev releases all pagerefs and builds up a new dirty list until the
+next writeback occurs.
+
+Using pagerefs has a number of benefits.
+
+For pages of the framebuffer, the deferred I/O code used struct
+page.lru as an entry into the list of dirty pages. The lru field is
+owned by the page cache, which makes deferred I/O incompatible with
+some memory pages (e.g., most notably DRM's GEM SHMEM allocator).
+struct fb_deferred_io_pageref now provides an entry into a list of
+dirty framebuffer pages, freeing lru for use with the page cache.
+
+Drivers also assumed that struct page.index is the page offset into
+the framebuffer. This is not true for DRM buffers, which are located
+at various offset within a mapped area. struct fb_deferred_io_pageref
+explicitly stores an offset into the framebuffer. struct page.index
+is now only the page offset into the mapped area.
+
+These changes will allow DRM to use fbdev deferred I/O without an
+intermediate shadow buffer.
+
+v3:
+ * use pageref->offset for sorting
+ * fix grammar in comment
+v2:
+ * minor fixes in commit message

+Subject: mwifiex: Select firmware based on strapping
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Andrejs Cainikovs <andrejs.cainikovs@toradex.com>
+
+[ Upstream commit 255ca28a659d3cfb069f73c7644853ed93aecdb0 ]
+
+Some WiFi/Bluetooth modules might have different host connection
+options, allowing to either use SDIO for both WiFi and Bluetooth,
+or SDIO for WiFi and UART for Bluetooth. It is possible to detect
+whether a module has SDIO-SDIO or SDIO-UART connection by reading
+its host strap register.
+
+This change introduces a way to automatically select appropriate
+firmware depending of the connection method, and removes a need
+of symlinking or overwriting the original firmware file with a
+required one.
+
+Host strap register used in this commit comes from the NXP driver [1]
+hosted at Code Aurora.

+Subject: scripts/decode_stacktrace.sh: optionally use LLVM utilities
+
+From: Carlos Llamas <cmllamas@google.com>
+
+[ Upstream commit efbd6398353315b7018e6943e41fee9ec35e875f ]
+
+GNU's addr2line can have problems parsing a vmlinux built with LLVM,
+particularly when LTO was used. In order to decode the traces correctly
+this patch adds the ability to switch to LLVM's utilities readelf and
+addr2line. The same approach is followed by Will in [1].
+
+Before:
+ $ scripts/decode_stacktrace.sh vmlinux < kernel.log
+ [17716.240635] Call trace:
+ [17716.240646] skb_cow_data (??:?)
+ [17716.240654] esp6_input (ld-temp.o:?)
+ [17716.240666] xfrm_input (ld-temp.o:?)
+ [17716.240674] xfrm6_rcv (??:?)
+ [...]
+
+After:
+ $ LLVM=1 scripts/decode_stacktrace.sh vmlinux < kernel.log
+ [17716.240635] Call trace:
+ [17716.240646] skb_cow_data (include/linux/skbuff.h:2172 net/core/skbuff.c:4503)
+ [17716.240654] esp6_input (net/ipv6/esp6.c:977)
+ [17716.240666] xfrm_input (net/xfrm/xfrm_input.c:659)
+ [17716.240674] xfrm6_rcv (net/ipv6/xfrm6_input.c:172)
+ [...]
+
+Note that one could set CROSS_COMPILE=llvm- instead to hack around this
+issue. However, doing so can break the decodecode routine as it will
+force the selection of other LLVM utilities down the line e.g. llvm-as.

+
+The UART supports an auto-RTS mode in which the RTS pin is automatically
+activated during transmission. So mark this mode as being supported even
+if RTS is not controlled by the driver but the UART.
+
+Also the serial core expects now at least one of both modes rts-on-send or
+rts-after-send to be supported. This is since during sanitization
+unsupported flags are deleted from a RS485 configuration set by userspace.
+However if the configuration ends up with both flags unset, the core prints
+a warning since it considers such a configuration invalid (see
+uart_sanitize_serial_rs485()).

+

+
+Since we can't guarantee that the host won't send new Setup packet
+before going through the device-initiated disconnect, don't prepare
+beyond the Setup stage and keep the device in EP0_SETUP_PHASE. This
+ensures that the device-initated disconnect sequence can go through

+command if it can't DMA out the Setup packet.

+Subject: usb: dwc3: Fix ep0 handling when getting reset while doing control
+ transfer
+
+From: Mayank Rana <quic_mrana@quicinc.com>
+
+[ Upstream commit 9d778f0c5f95ca5aa2ff628ea281978697e8d89b ]
+
+According to the databook ep0 should be in setup phase during reset.
+If host issues reset between control transfers, ep0 will be in an
+invalid state. Fix this by issuing stall and restart on ep0 if it
+is not in setup phase.
+
+Also SW needs to complete pending control transfer and setup core for
+next setup stage as per data book. Hence check ep0 state during reset
+interrupt handling and make sure active transfers on ep0 out/in
+endpoint are stopped by queuing ENDXFER command for that endpoint and
+restart ep0 out again to receive next setup packet.

+
+[ Upstream commit e1ee843488d58099a89979627ef85d5bd6c5cacd ]
+
+If any function drivers request for a delayed status phase, this leads to a
+SETUP transfer timeout error, since the function may take longer to process
+the DATA stage. This eventually results in end transfer timeouts, as there
+is a pending SETUP transaction.
+
+In addition, allow the DWC3_EP_DELAY_STOP to be set for if there is a
+delayed status requested. Ocasionally, a host may abort the current SETUP
+transaction, by issuing a subsequent SETUP token. In those situations, it
+would result in an endxfer timeout as well.

+
+[ Upstream commit 730e12fbec53ab59dd807d981a204258a4cfb29a ]
+
+Current EP0 dequeue path will share the same as other EPs. However, there
+are some special considerations that need to be made for EP0 transfers:
+
+ - EP0 transfers never transition into the started_list
+ - EP0 only has one active request at a time
+
+In case there is a vendor specific control message for a function over USB
+FFS, then there is no guarantee on the timeline which the DATA/STATUS stage
+is responded to. While this occurs, any attempt to end transfers on
+non-control EPs will end up having the DWC3_EP_DELAY_STOP flag set, and
+defer issuing of the end transfer command. If the USB FFS application
+decides to timeout the control transfer, or if USB FFS AIO path exits, the
+USB FFS driver will issue a call to usb_ep_dequeue() for the ep0 request.
+
+In case of the AIO exit path, the AIO FS blocks until all pending USB
+requests utilizing the AIO path is completed. However, since the dequeue
+of ep0 req does not happen properly, all non-control EPs with the
+DWC3_EP_DELAY_STOP flag set will not be handled, and the AIO exit path will
+be stuck waiting for the USB FFS data endpoints to receive a completion
+callback.
+
+Fix is to utilize dwc3_ep0_reset_state() in the dequeue API to ensure EP0
+is brought back to the SETUP state, and ensures that any deferred end
+transfer commands are handled. This also will end any active transfers
+on EP0, compared to the previous implementation which directly called
+giveback only.

+The driver shouldn't be able to issue End Transfer to the control

+as invalid/unexpected direction of Data Phase as described in the
+control transfer flow of the programming guide. It _may_ end started
+data phase during controller deinitialization from soft disconnect or
+driver removal. However, that should not happen because the driver
+should be maintained in EP0_SETUP_PHASE during driver tear-down. On
+soft-connect, the controller should be reset from a soft-reset and there
+should be no issue starting the control endpoint.

+Subject: usb: dwc3: gadget: Queue PM runtime idle on disconnect event
+
+From: Wesley Cheng <quic_wcheng@quicinc.com>
+
+[ Upstream commit 3c7af52c7616c3aa6dacd2336ec748d4a65df8f4 ]
+
+There is a scenario where DWC3 runtime suspend is blocked due to the
+dwc->connected flag still being true while PM usage_count is zero after
+DWC3 giveback is completed and the USB gadget session is being terminated.
+This leads to a case where nothing schedules a PM runtime idle for the
+device.
+
+The exact condition is seen with the following sequence:
+ 1. USB bus reset is issued by the host
+ 2. Shortly after, or concurrently, a USB PD DR SWAP request is received
+ (sink->source)
+ 3. USB bus reset event handler runs and issues
+ dwc3_stop_active_transfers(), and pending transfer are stopped
+ 4. DWC3 usage_count decremented to 0, and runtime idle occurs while
+ dwc->connected == true, returns -EBUSY
+ 5. DWC3 disconnect event seen, dwc->connected set to false due to DR
+ swap handling
+ 6. No runtime idle after this point
+
+Address this by issuing an asynchronous PM runtime idle call after the
+disconnect event is completed, as it modifies the dwc->connected flag,
+which is what blocks the initial runtime idle.

+Subject: usb: dwc3: gadget: Stall and restart EP0 if host is unresponsive
+
+From: Wesley Cheng <quic_wcheng@quicinc.com>
+
+[ Upstream commit 02435a739b81ae24aff5d6e930efef9458e2af3c ]
+
+It was observed that there are hosts that may complete pending SETUP
+transactions before the stop active transfers and controller halt occurs,
+leading to lingering endxfer commands on DEPs on subsequent pullup/gadget
+start iterations.
+
+ dwc3_gadget_ep_disable name=ep8in flags=0x3009 direction=1
+ dwc3_gadget_ep_disable name=ep4in flags=1 direction=1
+ dwc3_gadget_ep_disable name=ep3out flags=1 direction=0
+ usb_gadget_disconnect deactivated=0 connected=0 ret=0
+
+The sequence shows that the USB gadget disconnect (dwc3_gadget_pullup(0))
+routine completed successfully, allowing for the USB gadget to proceed with
+a USB gadget connect. However, if this occurs the system runs into an
+issue where:
+
+ BUG: spinlock already unlocked on CPU
+ spin_bug+0x0
+ dwc3_remove_requests+0x278
+ dwc3_ep0_out_start+0xb0
+ __dwc3_gadget_start+0x25c
+
+This is due to the pending endxfers, leading to gadget start (w/o lock
+held) to execute the remove requests, which will unlock the dwc3
+spinlock as part of giveback.
+
+To mitigate this, resolve the pending endxfers on the pullup disable
+path by re-locating the SETUP phase check after stop active transfers, since
+that is where the DWC3_EP_DELAY_STOP is potentially set. This also allows
+for handling of a host that may be unresponsive by using the completion
+timeout to trigger the stall and restart for EP0.

+
+If a Setup packet is received but yet to DMA out, the controller will
+not process the End Transfer command of any endpoint. Polling of its
+DEPCMD.CmdAct may block setting up TRB for Setup packet, causing a
+command timeout.
+
+This may occur if the driver doesn’t service the completion interrupt of
+the control status stage yet due to system latency, then it won’t
+prepare TRB and start the transfer for the next Setup Stage. To the host
+side, the control transfer had completed, and the host can send a new
+Setup packet at this point.
+
+In the meanwhile, if the driver receives an async call to dequeue a
+request (triggering End Transfer) to any endpoint, then the driver will
+service that End transfer first, blocking the control status stage
+completion handler. Since no TRB is available for the Setup stage, the
+Setup packet can’t be DMA’ed out and the End Transfer gets hung.
+
+The driver must not block setting up of the Setup stage. So track and
+only issue the End Transfer command only when there’s Setup TRB prepared
+so that the controller can DMA out the Setup packet. Delay the End
+transfer command if there's no Setup TRB available. This is applicable to
+all DWC_usb3x IPs.

+Subject: wifi: mwifiex: add extra delay for firmware ready
+
+From: David Lin <yu-hao.lin@nxp.com>
+
+[ Upstream commit 1c5d463c0770c6fa2037511a24fb17966fd07d97 ]
+
+For SDIO IW416, due to a bug, FW may return ready before complete full
+initialization. Command timeout may occur at driver load after reboot.
+Workaround by adding 100ms delay at checking FW status.

+Subject: wifi: mwifiex: Support SD8978 chipset
+
+From: Lukas Wunner <lukas@wunner.de>
+
+[ Upstream commit bba047f15851c8b053221f1b276eb7682d59f755 ]
+
+The Marvell SD8978 (aka NXP IW416) uses identical registers as SD8987,
+so reuse the existing mwifiex_reg_sd8987 definition.
+
+Note that mwifiex_reg_sd8977 and mwifiex_reg_sd8997 are likewise
+identical, save for the fw_dump_ctrl register: They define it as 0xf0
+whereas mwifiex_reg_sd8987 defines it as 0xf9. I've verified that
+0xf9 is the correct value on SD8978. NXP's out-of-tree driver uses
+0xf9 for all of them, so there's a chance that 0xf0 is not correct
+in the mwifiex_reg_sd8977 and mwifiex_reg_sd8997 definitions. I cannot
+test that for lack of hardware, hence am leaving it as is.
+
+NXP has only released a firmware which runs Bluetooth over UART.
+Perhaps Bluetooth over SDIO is unsupported by this chipset.
+Consequently, only an "sdiouart" firmware image is referenced, not an
+alternative "sdsd" image.
