2026-04-16crypto: sa2ul - Fix AEAD fallback algorithm namesT Pratham
For authenc AEAD algorithms, sa2ul is trying to register very specific -ce version as a fallback. This causes registration failure on SoCs which do not have ARMv8-CE enabled/available. Change the fallback algorithm from the specific driver name to generic algorithm name so that the kernel can allocate any available fallback.

2026-04-16crypto: eip93 - fix hmac setkey algo selectionAleksander Jan Bajkowski
eip93_hmac_setkey() allocates a temporary ahash transform for computing HMAC ipad/opad key material. The allocation uses the driver-specific cra_driver_name (e.g. "sha256-eip93") but passes CRYPTO_ALG_ASYNC as the mask, which excludes async algorithms. Since the EIP93 hash algorithms are the only ones registered under those driver names and they are inherently async, the lookup is self-contradictory and always fails with -ENOENT. When called from the AEAD setkey path, this failure leaves the SA record partially initialized with zeroed digest fields. A subsequent crypto operation then dereferences a NULL pointer in the request context, resulting in a kernel panic: ``` pc : eip93_aead_handle_result+0xc8c/0x1240 [crypto_hw_eip93] lr : eip93_aead_handle_result+0xbec/0x1240 [crypto_hw_eip93] sp : ffffffc082feb820 x29: ffffffc082feb820 x28: ffffff8011043980 x27: 0000000000000000 x26: 0000000000000000 x25: ffffffc078da0bc8 x24: 0000000091043980 x23: ffffff8004d59e50 x22: ffffff8004d59410 x21: ffffff8004d593c0 x20: ffffff8004d593c0 x19: ffffff8004d4f300 x18: 0000000000000000 x17: 0000000000000000 x16: 0000000000000000 x15: 0000007fda7aa498 x14: 0000000000000000 x13: 0000000000000000 x12: 0000000000000000 x11: 0000000000000000 x10: fffffffff8127a80 x9 : 0000000000000000 x8 : ffffff8004d4f380 x7 : 0000000000000000 x6 : 000000000000003f x5 : 0000000000000040 x4 : 0000000000000008 x3 : 0000000000000009 x2 : 0000000000000008 x1 : 0000000028000003 x0 : ffffff8004d388c0 Code: 910142b6 f94012e0 f9002aa0 f90006d3 (f9400740) ``` The reported symbol eip93_aead_handle_result+0xc8c is a resolution artifact from static functions being merged under the nearest exported symbol.

Fix this by dropping the CRYPTO_ALG_ASYNC mask from the crypto_alloc_ahash() call. The code already handles async completion correctly via crypto_wait_req(), so there is no requirement to restrict the lookup to synchronous algorithms. Note that hashing a single 64-byte block through the hardware is likely slower than doing it in software due to the DMA round-trip overhead, but offloading it may still spare CPU cycles on the slower embedded cores where this IP is found.

of_drm_find_bridge() is deprecated. Move to its replacement of_drm_find_and_get_bridge() which gets a bridge reference, and ensure it is put when done. This is made somewhat simpler by the fact that 'bridge' is a local variable. However we need to handle both branches of the main if(). In the 'else' case, just switch to of_drm_find_and_get_bridge() to ensure the bridge is not freed while in use in the function tail (drm_bridge_attach() mainly). In the 'then' case, devm_drm_panel_bridge_add_typed() already increments the refcount using devres which ties the bridge allocation lifetime to the device lifetime, so we would not need to do anything. However to have the same behaviour in both branches take an additional reference here, so that the bridge needs to be put whichever branch is taken without more complicated logic.

2026-04-16drm/bridge: prevent encoder chain changes in pre_enable/post_disableLuca Ceresoli
Take the encoder chain mutex while iterating over the encoder chain in drm_atomic_bridge_chain_pre_enable() and drm_atomic_bridge_chain_post_disable() to ensure the lists won't change while being inspected. These functions have nested list_for_each_*() loops, which makes them complicated. list_for_each_entry_from() loops could be replaced by drm_for_each_bridge_in_chain_from(), but it would not work in a nested way in its current implementation. Besides, there is no "_reverse" variant of drm_for_each_bridge_in_chain_from(). Keep code simple and readable by explicitly locking around the outer loop. Thankfully there are no break or return points inside the loops, so the change is trivial and readable.

2026-04-16drm/encoder: drm_encoder_cleanup: lock the encoder chain mutex during removalLuca Ceresoli
drm_encoder_cleanup() modifies the encoder chain by removing bridges via drm_bridge_detach(). Protect this whole operation by taking the mutex, so that: * any users iterating over the chain will not access it during the change * other code willing to modify the list (drm_bridge_attach()) will wait until drm_encoder_cleanup() is done Note that the _safe macro in use here is providing a different and orthogonal kind of protection than the mutex: 1. list_for_each_entry_safe() allows removing the current entry from the list it is iterating on, synchronously; the non-safe version would be unable to find the next entry after the current entry has been removed 2. the mutex being added allows to ensure that the list is not used asynchronously by other code while it is being modified; this prevents such other concurrent code to derail because it is iterating over an element while it is removed The _safe macro, which works by taking the "next" pointer in addition to the "current" one, does not even try to provide the protection at item 2 above. This is visible e.g. when the "next" element is removed by other concurrent code. This is what would happen without the added mutex: 1. start loop: list_for_each_entry_safe(pos, n, ...) sets: pos = list_first_entry() = (bridge 1) n = list_next_entry(pos) = (bridge 2) 2. enter the loop 1st time, do something with *pos (bridge 1) 3. in the meanwhile bridge 2 is hot-unplugged -> another thread removes bridge 2 -> drm_bridge_detach() -> list_del() sets (bridge 2)->next = LIST_POISON1 4. loop iteration 1 finishes, list_for_each_entry_safe() sets: pos = n (previously set to bridge 2) n = (bridge 2)->next = LIST_POISON1 5. enter the loop 2nd time, do something with *pos (bridge 2) 6. loop iteration 2 finishes, list_for_each_entry_safe() sets: pos = n = LIST_POISON1 ==> bug! However, simply adding mutex_[un]lock(&encoder->bridge_chain_mutex) before/after the list_for_each_entry_safe() seems a simple and good solution, but it is introducing a possible ABBA deadlock (found by PROVE_LOCKING). The two code paths involved are: * drm_encoder_cleanup(): - takes the bridge_chain_mutex (A) - calls drm_bridge_detach -> drm_atomic_private_obj_fini -> DRM_MODESET_LOCK_ALL_BEGIN() which takes all locks in the acquisition context (B) * drm_mode_getconnector() (and other code paths): - calls drm_helper_probe_single_connector_modes() which: - takes a drm_modeset_lock in the acquisition context (B) - calls __drm_helper_update_and_validate -> drm_bridge_chain_mode_valid -> drm_for_each_bridge_in_chain_from() which takes the bridge_chain_mutex (A) To avoid this potential ABBA deadlock, move all list items to a temporary list while holding the bridge_chain_mutex, then detach all elements from the temporary list without the mutex.

2026-04-16drm/encoder: add mutex to protect the bridge chainLuca Ceresoli
The per-encoder bridge chain is currently assumed to be static once it is fully initialized. Work is in progress to add hot-pluggable bridges, breaking that assumption. With bridge removal, the encoder chain can change without notice, removing tail bridges. This can be problematic while iterating over the chain. Add a mutex to be taken whenever looping or changing the encoder chain.

The RZ/G2L hardware manual (Rev. 1.50, May 2025), Section 34.4.2.1, requires deasserting the CMN_RSTB signal after setting the Link registers. Move the reset_control_deassert() call from rzg2l_mipi_dsi_dphy_init() to rzg2l_mipi_dsi_startup(), placing it after the Link register writes. This reset signal is optional for RZ/V2H SoCs, so add a NULL check. Drop the unused ret variable from rzg2l_mipi_dsi_dphy_init(). The CMN_RSTB signal is not required for reading PHY registers in the probe. Move reset_control_assert() from rzg2l_mipi_dsi_dphy_exit() to rzg2l_mipi_dsi_stop(), placing it before the dphy_exit() call. Since this reset signal is optional for RZ/V2H, the call is a no-op on that SoC.

2026-04-16pwm: stm32: Fix rounding issue for requests with inverted polarityUwe Kleine-König
The calculation of the number of pwm clk ticks from a time length in nanoseconds involves a division and thus some rounding. That might result in duty_ticks + offset_ticks < period_ticks despite duty_length_ns + duty_offset_ns >= period_length_ns . The stm32 PWM cannot configure offset_ticks freely, it can only select 0 or period_length_ns - duty_length_ns---that is the classic normal and inverted polarity. The decision to select the hardware polarity must be done using the ticks values and not the nanoseconds times to adhere to the rounding rules by the pwm core. With the pwm clk running at 208900 kHz on my test machine (stm32mp135f-dk), a test case that was handled wrong is: # pwmround -P 9999962 -O 24970 -D 9974992 period_length = 9999962 duty_length = 9974840 duty_offset = 25123 With this change applied the rounding is done correctly: # pwmround -P 9999962 -O 24970 -D 9974992 period_length = 9999962 duty_length = 9974840 duty_offset = 0 Fixes: deaba9cff809 ("pwm: stm32: Implementation of the waveform callbacks") Signed-off-by: Uwe Kleine-König <u.kleine-koenig@baylibre.com> Link: https://patch.msgid.link/c5e7767cee821b5f6e00f95bd14a5e13015646fb.1776264104.git.u.kleine-koenig@baylibre.com Signed-off-by: Uwe Kleine-König <ukleinek@kernel.org>

2026-04-15drm/xe: Suppress reset log for killed queuesDaniele Ceraolo Spurio
When an app exits abruptly (for example due to the user hitting ctrl+c), any of its queues that are still active on the HW are immediately killed. As part of this process, the driver tells the GuC to preempt the queues off the HW and to reset them if they don't preempt. This can cause a reset log to be printed to dmesg, which can be confusing to users as resets are commonly tied to errors, while any resets performed in this case are just done to speed up the cleanup. Also, those reset messages are not useful for debug, because we don't care what happens to a queue once its app has exited. The only case where a queue might be killed before the app that owns it has exited is if the queue uses PXP and a PXP termination occurs. In such scenario a log might be useful, but rather than a reset log it is better to have a communication that the queue is being killed. Therefore, we can silence the reset log for all killed queues and add a simple debug log to record when a PXP queue is killed to cover that case.

Adjust struct fatal_error_info to match the expected driver/firmware interface layout. The structure is used to retrieve debug information from firmware when a command becomes stuck on the device. The reserved field currently uses 128 u32 entries, which makes the structure larger than intended and causes the layout to no longer match the firmware definition.
