[PATCH v2] usb: gadget: f_midi: Fixing wMaxPacketSize exceeded issue during MIDI bind retries

by Selvarasu Ganesan

The current implementation sets the wMaxPacketSize of bulk in/out endpoints to 1024 bytes at the end of the f_midi_bind function. However, in cases where there is a failure in the first midi bind attempt, consider rebinding. This scenario may encounter an f_midi_bind issue due to the previous bind setting the bulk endpoint's wMaxPacketSize to 1024 bytes, which exceeds the ep->maxpacket_limit where configured dwc3 TX/RX FIFO's maxpacket size of 512 bytes for IN/OUT endpoints in support HS speed only. Here the term "rebind" in this context refers to attempting to bind the MIDI function a second time in certain scenarios. The situations where rebinding is considered include: * When there is a failure in the first UDC write attempt, which may be caused by other functions bind along with MIDI. * Runtime composition change : Example : MIDI,ADB to MIDI. Or MIDI to MIDI,ADB. This commit addresses this issue by resetting the wMaxPacketSize before endpoint claim. And here there is no need to reset all values in the usb endpoint descriptor structure, as all members except wMaxPacketSize and bEndpointAddress have predefined values. This ensures that restores the endpoint to its expected configuration, and preventing conflicts with value of ep->maxpacket_limit. It also aligns with the approach used in other function drivers, which treat endpoint descriptors as if they were full speed before endpoint claim.

[PATCH 6.1] nvme: fix metadata handling in nvme-passthrough

by Hagar Hemdan

From: Puranjay Mohan <pjy(a)amazon.com> [ Upstream commit 7c2fd76048e95dd267055b5f5e0a48e6e7c81fd9 ] On an NVMe namespace that does not support metadata, it is possible to send an IO command with metadata through io-passthru. This allows issues like [1] to trigger in the completion code path. nvme_map_user_request() doesn't check if the namespace supports metadata before sending it forward. It also allows admin commands with metadata to be processed as it ignores metadata when bdev == NULL and may report success. Reject an IO command with metadata when the NVMe namespace doesn't support it and reject an admin command if it has metadata.

[PATCH v2] kbuild: switch from lz4c to lz4 for compression

by Parth Pancholi

From: Parth Pancholi <parth.pancholi(a)toradex.com> 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.

[PATCH v2 0/4] alpha: stack fixes

by Ivan Kokshaysky

This series fixes oopses on Alpha/SMP observed since kernel v6.9. [1] Thanks to Magnus Lindholm for identifying that remarkably longstanding bug. The problem is that GCC expects 16-byte alignment of the incoming stack since early 2004, as Maciej found out [2]: Having actually dug speculatively I can see that the psABI was changed in GCC 3.5 with commit e5e10fb4a350 ("re PR target/14539 (128-bit long double improperly aligned)") back in Mar 2004, when the stack pointer alignment was increased from 8 bytes to 16 bytes, and arch/alpha/kernel/entry.S has various suspicious stack pointer adjustments, starting with SP_OFF which is not a whole multiple of 16. Also, as Magnus noted, "ALPHA Calling Standard" [3] required the same: D.3.1 Stack Alignment This standard requires that stacks be octaword aligned at the time a new procedure is invoked. However: - the "normal" kernel stack is always misaligned by 8 bytes, thanks to the odd number of 64-bit words in 'struct pt_regs', which is the very first thing pushed onto the kernel thread stack; - syscall, fault, interrupt etc. handlers may, or may not, receive aligned stack depending on numerous factors. Somehow we got away with it until recently, when we ended up with a stack corruption in kernel/smp.c:smp_call_function_single() due to its use of 32-byte aligned local data and the compiler doing clever things allocating it on the stack. Patches 1-2 are preparatory; 3 - the main fix; 4 - fixes remaining special cases. Ivan.

[PATCH v8 02/13] drm/bridge: cdns-dsi: Fix phy de-init and flag it so

by Aradhya Bhatia

From: Aradhya Bhatia <a-bhatia1(a)ti.com> The driver code doesn't have a Phy de-initialization path as yet, and so it does not clear the phy_initialized flag while suspending. This is a problem because after resume the driver looks at this flag to determine if a Phy re-initialization is required or not. It is in fact required because the hardware is resuming from a suspend, but the driver does not carry out any re-initialization causing the D-Phy to not work at all. Call the counterparts of phy_init() and phy_power_on(), that are phy_exit() and phy_power_off(), from _bridge_post_disable(), and clear the flags so that the Phy can be initialized again when required.

[PATCH] arm64: kprobe: fix an error in single stepping support

by 1534428646＠qq.com

From: "Yiren Xie" <1534428646(a)qq.com> It is obvious a conflict between the code and the comment. The function aarch64_insn_is_steppable is used to check if a mrs instruction can be safe in single-stepping environment, in the comment it says only reading DAIF bits by mrs is safe in single-stepping environment, and other mrs instructions are not. So aarch64_insn_is_steppable should returen "TRUE" if the mrs instruction being single stepped is reading DAIF bits. And have verified using a kprobe kernel module which reads the DAIF bits by function arch_local_irq_save with offset setting to 0x4, confirmed that without this modification, it encounters "kprobe_init: register_kprobe failed, returned -22" error while inserting the kprobe kernel module. and with this modification, it can read the DAIF bits in single-stepping environment.
