+Subject: ALSA: usb-audio: Add delay quirk for iBasso DC07 Pro
+
+From: Lianqin Hu <hulianqin@vivo.com>
+
+commit d85fc52cbb9a719c8335d93a28d6a79d7acd419f upstream.
+
+Audio control requests that sets sampling frequency sometimes fail on
+this card. Adding delay between control messages eliminates that problem.

+Subject: drivers/card_reader/rtsx_usb: Restore interrupt based detection
+
+From: Sean Rhodes <sean@starlabs.systems>
+
+commit 235b630eda072d7e7b102ab346d6b8a2c028a772 upstream.
+
+This commit reintroduces interrupt-based card detection previously
+used in the rts5139 driver. This functionality was removed in commit
+00d8521dcd23 ("staging: remove rts5139 driver code").
+
+Reintroducing this mechanism fixes presence detection for certain card
+readers, which with the current driver, will taken approximately 20
+seconds to enter S3 as `mmc_rescan` has to be frozen.
+
+Fixes: 00d8521dcd23 ("staging: remove rts5139 driver code")

+Subject: kbuild: switch from lz4c to lz4 for compression
+
+From: Parth Pancholi <parth.pancholi@toradex.com>
+
+commit e397a603e49cc7c7c113fad9f55a09637f290c34 upstream.
+
+Replace lz4c with lz4 for kernel image compression.
+Although lz4 and lz4c are functionally similar, lz4c has been deprecated
+upstream since 2018. Since as early as Ubuntu 16.04 and Fedora 25, lz4
+and lz4c have been packaged together, making it safe to update the
+requirement from lz4c to lz4.
+
+Consequently, some distributions and build systems, such as OpenEmbedded,
+have fully transitioned to using lz4. OpenEmbedded core adopted this
+change in commit fe167e082cbd ("bitbake.conf: require lz4 instead of
+lz4c"), causing compatibility issues when building the mainline kernel
+in the latest OpenEmbedded environment, as seen in the errors below.
+
+This change also updates the LZ4 compression commands to make it backward
+compatible by replacing stdin and stdout with the '-' option, due to some
+unclear reason, the stdout keyword does not work for lz4 and '-' works for
+both. In addition, this modifies the legacy '-c1' with '-9' which is also
+compatible with both. This fixes the mainline kernel build failures with
+the latest master OpenEmbedded builds associated with the mentioned
+compatibility issues.

+From: Ricardo B. Marliere <rbm@suse.com>
+
+commit a4e17a8f239a545c463f8ec27db4ed6e74b31841 upstream.
+
+In the case of a test that uses the special option ${KERNEL_VERSION} in one
+of its settings but has no configuration available in ${OUTPUT_DIR}, for
+example if it's a new empty directory, then the `make kernelrelease` call
+will fail and the subroutine will chomp an empty string, silently. Fix that
+by adding an empty configuration and retrying.

+Subject: net: usb: rtl8150: enable basic endpoint checking
+
+From: Nikita Zhandarovich <n.zhandarovich@fintech.ru>
+
+commit 90b7f2961798793275b4844348619b622f983907 upstream.
+
+Syzkaller reports [1] encountering a common issue of utilizing a wrong
+usb endpoint type during URB submitting stage. This, in turn, triggers
+a warning shown below.
+
+For now, enable simple endpoint checking (specifically, bulk and
+interrupt eps, testing control one is not essential) to mitigate
+the issue with a view to do other related cosmetic changes later,
+if they are necessary.
+
+[1] Syzkaller report:

+From: Pablo Neira Ayuso <pablo@netfilter.org>
+
+commit 1b9335a8000fb70742f7db10af314104b6ace220 upstream.
+
+The field length description provides the length of each separated key
+field in the concatenation, each field gets rounded up to 32-bits to
+calculate the pipapo rule width from pipapo_init(). The set key length
+provides the total size of the key aligned to 32-bits.
+
+Register-based arithmetics still allows for combining mismatching set
+key length and field length description, eg. set key length 10 and field
+description [ 5, 4 ] leading to pipapo width of 12.

+Subject: Revert "SUNRPC: Reduce thread wake-up rate when receiving large RPC messages"
+
+From: Chuck Lever <chuck.lever@oracle.com>
+
+commit 966a675da844f1a764bb44557c21561cc3d09840 upstream.
+
+I noticed that a handful of NFSv3 fstests were taking an
+unexpectedly long time to run. Troubleshooting showed that the
+server's TCP window closed and never re-opened, which caused the
+client to trigger an RPC retransmit timeout after 180 seconds.
+
+The client's recovery action was to establish a fresh connection
+and retransmit the timed-out requests. This worked, but it adds a
+long delay.
+
+I tracked the problem to the commit that attempted to reduce the
+rate at which the network layer delivers TCP socket data_ready
+callbacks. Under most circumstances this change worked as expected,
+but for NFSv3, which has no session or other type of throttling, it
+can overwhelm the receiver on occasion.
+
+I'm sure I could tweak the lowat settings, but the small benefit
+doesn't seem worth the bother. Just revert it.

+Subject: selftests/rseq: Fix handling of glibc without rseq support
+
+From: Mathieu Desnoyers <mathieu.desnoyers@efficios.com>
+
+commit 336d02bc4c6bec5c3d933e5d470a94970f830957 upstream.
+
+When porting librseq commit:
+
+commit c7b45750fa85 ("Adapt to glibc __rseq_size feature detection")
+
+from librseq to the kernel selftests, the following line was missed
+at the end of rseq_init():
+
+ rseq_size = get_rseq_kernel_feature_size();
+
+which effectively leaves rseq_size initialized to -1U when glibc does not
+have rseq support. glibc supports rseq from version 2.35 onwards.
+
+In a following librseq commit
+
+commit c67d198627c2 ("Only set 'rseq_size' on first thread registration")
+
+to mimic the libc behavior, a new approach is taken: don't set the
+feature size in 'rseq_size' until at least one thread has successfully
+registered. This allows using 'rseq_size' in fast-paths to test for both
+registration status and available features. The caveat is that on libc
+either all threads are registered or none are, while with bare librseq
+it is the responsability of the user to register all threads using rseq.
+
+This combines the changes from the following librseq git commits:
+
+commit c7b45750fa85 ("Adapt to glibc __rseq_size feature detection")
+commit c67d198627c2 ("Only set 'rseq_size' on first thread registration")
+

+Subject: usb: dwc3: core: Defer the probe until USB power supply ready
+
+From: Kyle Tso <kyletso@google.com>
+
+commit 66e0ea341a2a78d14336117f19763bd9be26d45d upstream.
+
+Currently, DWC3 driver attempts to acquire the USB power supply only
+once during the probe. If the USB power supply is not ready at that
+time, the driver simply ignores the failure and continues the probe,
+leading to permanent non-functioning of the gadget vbus_draw callback.
+
+Address this problem by delaying the dwc3 driver initialization until
+the USB power supply is registered.

+Subject: usb: typec: tcpci: Prevent Sink disconnection before vPpsShutdown in SPR PPS
+
+From: Kyle Tso <kyletso@google.com>
+
+commit 4d27afbf256028a1f54363367f30efc8854433c3 upstream.
+
+The Source can drop its output voltage to the minimum of the requested
+PPS APDO voltage range when it is in Current Limit Mode. If this voltage
+falls within the range of vPpsShutdown, the Source initiates a Hard
+Reset and discharges Vbus. However, currently the Sink may disconnect
+before the voltage reaches vPpsShutdown, leading to unexpected behavior.
+
+Prevent premature disconnection by setting the Sink's disconnect
+threshold to the minimum vPpsShutdown value. Additionally, consider the
+voltage drop due to IR drop when calculating the appropriate threshold.
+This ensures a robust and reliable interaction between the Source and
+Sink during SPR PPS Current Limit Mode operation.

+Subject: usb: xhci: Fix NULL pointer dereference on certain command aborts
+
+From: Michal Pecio <michal.pecio@gmail.com>
+
+commit 1e0a19912adb68a4b2b74fd77001c96cd83eb073 upstream.
+
+If a command is queued to the final usable TRB of a ring segment, the
+enqueue pointer is advanced to the subsequent link TRB and no further.
+If the command is later aborted, when the abort completion is handled
+the dequeue pointer is advanced to the first TRB of the next segment.
+
+If no further commands are queued, xhci_handle_stopped_cmd_ring() sees
+the ring pointers unequal and assumes that there is a pending command,
+so it calls xhci_mod_cmd_timer() which crashes if cur_cmd was NULL.
+
+Don't attempt timer setup if cur_cmd is NULL. The subsequent doorbell
+ring likely is unnecessary too, but it's harmless. Leave it alone.
+
+This is probably Bug 219532, but no confirmation has been received.
+
+The issue has been independently reproduced and confirmed fixed using
+a USB MCU programmed to NAK the Status stage of SET_ADDRESS forever.
+Everything continued working normally after several prevented crashes.
