Since both stable/linux-6.1.y and stable/linux-6.6.y branches don't have b75197e86e6d ("md: Remove flush handling") there is a minor issue with this backport. Statement "previous patch cleaned md_write_start(), make_requst() only return error in raid5_make_request() by dm-raid" will not work for both branches since 03e792eaf18e ("md: change the return value type of md_write_start to void") was not backported. So we should either backport it, or do error handling, not the WARN_ON_ONCE(). -- Andrew Kanner

It implements an interface for a new feature added in in 6.15, but without backporting that feature, nothing will use the new interface so this patch is unnecessary.

Obviously, this could lead to memory waste as we allocated memory based on larger maxpages, besides, this could lead to a potensial deadloop as following: 1) When calling setup_clusters() with larger maxpages, unavailable pages within range [si->max, larger maxpages) are not accounted with inc_cluster_info_page(). As a result, these pages are assumed available but can not be allocated. The cluster contains these pages can be moved to frag_clusters list after it's all available pages were allocated. 2) When the cluster mentioned in 1) is the only cluster in frag_clusters list, cluster_alloc_swap_entry() assume order 0 allocation will never failed and will enter a deadloop by keep trying to allocate page from the only cluster in frag_clusters which contains no actually available page. Call setup_swap_extents() to get the final maxpages before swap_info_struct initialization to fix the issue.

[PATCH v1] Revert "usb: xhci: Implement xhci_handshake_check_state() helper"

by Roy Luo

This reverts commit 6ccb83d6c4972ebe6ae49de5eba051de3638362c. Commit 6ccb83d6c497 ("usb: xhci: Implement xhci_handshake_check_state() helper") was introduced to workaround watchdog timeout issues on some platforms, allowing xhci_reset() to bail out early without waiting for the reset to complete. Skipping the xhci handshake during a reset is a dangerous move. The xhci specification explicitly states that certain registers cannot be accessed during reset in section 5.4.1 USB Command Register (USBCMD), Host Controller Reset (HCRST) field: "This bit is cleared to '0' by the Host Controller when the reset process is complete. Software cannot terminate the reset process early by writinga '0' to this bit and shall not write any xHC Operational or Runtime registers until while HCRST is '1'." This behavior causes a regression on SNPS DWC3 USB controller with dual-role capability. When the DWC3 controller exits host mode and removes xhci while a reset is still in progress, and then tries to configure its hardware for device mode, the ongoing reset leads to register access issues; specifically, all register reads returns 0. These issues extend beyond the xhci register space (which is expected during a reset) and affect the entire DWC3 IP block, causing the DWC3 device mode to malfunction.

[PATCH v6 6/7] media: mt9m114: Fix deadlock in get_frame_interval/set_frame_interval

by Mathis Foerst

Getting / Setting the frame interval using the V4L2 subdev pad ops get_frame_interval/set_frame_interval causes a deadlock, as the subdev state is locked in the [1] but also in the driver itself. In [2] it's described that the caller is responsible to acquire and release the lock in this case. Therefore, acquiring the lock in the driver is wrong. Remove the lock acquisitions/releases from mt9m114_ifp_get_frame_interval() and mt9m114_ifp_set_frame_interval().

[PATCH v5 6/7] media: mt9m114: Fix deadlock in get_frame_interval/set_frame_interval

by Mathis Foerst

Getting / Setting the frame interval using the V4L2 subdev pad ops get_frame_interval/set_frame_interval causes a deadlock, as the subdev state is locked in the [1] but also in the driver itself. In [2] it's described that the caller is responsible to acquire and release the lock in this case. Therefore, acquiring the lock in the driver is wrong. Remove the lock acquisitions/releases from mt9m114_ifp_get_frame_interval() and mt9m114_ifp_set_frame_interval().

[PATCH 6.1 0/1] Oopses on module unload seen on 6.1.y

by Fedor Pchelkin

Hi, commit 959cadf09dbae7b304f03e039b8d8e13c529e2dd Author: Peter Zijlstra <peterz(a)infradead.org> Date: Mon Oct 14 10:05:48 2024 -0700 x86/its: Use dynamic thunks for indirect branches commit 872df34d7c51a79523820ea6a14860398c639b87 upstream. was ported at v6.1.139 and leads to kernel crashes there after module unload operations.

The allocated memory is vmalloc-based, and it ends up being ROX upon release inside its_free_mod(). Freeing of special permissioned memory in vmalloc requires its own handling. VM_FLUSH_RESET_PERMS flag was introduced for these purposes. In-kernel users dealing with the stuff had to care about this explicitly before commit 4c4eb3ecc91f ("x86/modules: Set VM_FLUSH_RESET_PERMS in module_alloc()"). More recent kernels starting from 6.2 have the commit and are not affected. So port it as a followup for ITS mitigation 6.1-series to fix the aforementioned failures. The problem concerns 5.15-series (currently in stable-queue) as well. It needs its own patch to apply cleanly. Will send it shortly, too. Found by Linux Verification Center (linuxtesting.org).

[PATCH net 1/4] can: kvaser_pciefd: Force IRQ edge in case of nested IRQ

From: Axel Forsman <axfo(a)kvaser.com> Avoid the driver missing IRQs by temporarily masking IRQs in the ISR to enforce an edge even if a different IRQ is signalled before handled IRQs are cleared.
