[PATCH] spi: Fix deadlock when adding SPI controllers on SPI buses

by Hardik Gohil

From: Mark Brown <broonie(a)kernel.org> [ Upstream commit 6098475d4cb48d821bdf453c61118c56e26294f0 ] Currently we have a global spi_add_lock which we take when adding new devices so that we can check that we're not trying to reuse a chip select that's already controlled. This means that if the SPI device is itself a SPI controller and triggers the instantiation of further SPI devices we trigger a deadlock as we try to register and instantiate those devices while in the process of doing so for the parent controller and hence already holding the global spi_add_lock. Since we only care about concurrency within a single SPI bus move the lock to be per controller, avoiding the deadlock. This can be easily triggered in the case of spi-mux.

Commit 6098475d4cb4 ("spi: Fix deadlock when adding SPI controllers on SPI buses") introduced a per-controller mutex.

[PATCH] drm/rockchip: cdn-dp: Use drm_connector_helper_hpd_irq_event()

by Thomas Zimmermann

The code for detecting and updating the connector status in cdn_dp_pd_event_work() has a number of problems. - It does not aquire the locks to call the detect helper and update the connector status. These are struct drm_mode_config.connection_mutex and struct drm_mode_config.mutex. - It does not use drm_helper_probe_detect(), which helps with the details of locking and detection. - It uses the connector's status field to determine a change to the connector status. The epoch_counter field is the correct one. The field signals a change even if the connector status' value did not change. Replace the code with a call to drm_connector_helper_hpd_irq_event(), which fixes all these problems.

[PATCH 6.1] Revert "wifi: mac80211: fix RCU list iterations"

by Fedor Pchelkin

This reverts commit b0b2dc1eaa7ec509e07a78c9974097168ae565b7 which is commit ac35180032fbc5d80b29af00ba4881815ceefcb6 upstream. The reverted commit is based heavily on wiphy locking changes made by the "wifi: cfg80211/mac80211: locking cleanups" series [1] introduced since 6.7 kernel and not supposed to be backported to old stable branches. It breaks locking rules in the context of old stables leading e.g. to the following lockdep splat there - ieee80211_get_max_required_bw() is actually called under RCU reader lock in 6.1/6.6, not the wiphy mutex.

AMD PMF on 6.11.y

by Mario Limonciello

Hi, 6.11 already supports most functionality of AMD family 0x1a model 0x60, but the amd-pmf driver doesn't load due to a missing device ID. The device ID was added in 6.12 with: commit 8ca8d07857c69 ("platform/x86/amd/pmf: Add SMU metrics table support for 1Ah family 60h model") Can this please come back to 6.11.y to enable it more widely? Thanks!

Possible dependencies: thanks, greg k-h ------------------ original commit in Linus's tree ------------------ From 8c462d56487e3abdbf8a61cedfe7c795a54f4a78 Mon Sep 17 00:00:00 2001 From: Mark Rutland <mark.rutland(a)arm.com> Date: Wed, 6 Nov 2024 16:04:48 +0000 Subject: [PATCH] arm64: smccc: Remove broken support for SMCCCv1.3 SVE discard hint SMCCCv1.3 added a hint bit which callers can set in an SMCCC function ID (AKA "FID") to indicate that it is acceptable for the SMCCC implementation to discard SVE and/or SME state over a specific SMCCC call. The kernel support for using this hint is broken and SMCCC calls may clobber the SVE and/or SME state of arbitrary tasks, though FPSIMD state is unaffected. The kernel support is intended to use the hint when there is no SVE or SME state to save, and to do this it checks whether TIF_FOREIGN_FPSTATE is set or TIF_SVE is clear in assembly code: | ldr <flags>, [<current_task>, #TSK_TI_FLAGS] | tbnz <flags>, #TIF_FOREIGN_FPSTATE, 1f // Any live FP state? | tbnz <flags>, #TIF_SVE, 2f // Does that state include SVE? | | 1: orr <fid>, <fid>, ARM_SMCCC_1_3_SVE_HINT | 2: | << SMCCC call using FID >> This is not safe as-is: (1) SMCCC calls can be made in a preemptible context and preemption can result in TIF_FOREIGN_FPSTATE being set or cleared at arbitrary points in time. Thus checking for TIF_FOREIGN_FPSTATE provides no guarantee. (2) TIF_FOREIGN_FPSTATE only indicates that the live FP/SVE/SME state in the CPU does not belong to the current task, and does not indicate that clobbering this state is acceptable. When the live CPU state is clobbered it is necessary to update fpsimd_last_state.st to ensure that a subsequent context switch will reload FP/SVE/SME state from memory rather than consuming the clobbered state. This and the SMCCC call itself must happen in a critical section with preemption disabled to avoid races. (3) Live SVE/SME state can exist with TIF_SVE clear (e.g. with only TIF_SME set), and checking TIF_SVE alone is insufficient. Remove the broken support for the SMCCCv1.3 SVE saving hint. This is effectively a revert of commits: * cfa7ff959a78 ("arm64: smccc: Support SMCCC v1.3 SVE register saving hint") * a7c3acca5380 ("arm64: smccc: Save lr before calling __arm_smccc_sve_check()") ... leaving behind the ARM_SMCCC_VERSION_1_3 and ARM_SMCCC_1_3_SVE_HINT definitions, since these are simply definitions from the SMCCC specification, and the latter is used in KVM via ARM_SMCCC_CALL_HINTS. If we want to bring this back in future, we'll probably want to handle this logic in C where we can use all the usual FPSIMD/SVE/SME helper functions, and that'll likely require some rework of the SMCCC code and/or its callers.

This is effectively a revert of commits: * cfa7ff959a78 ("arm64: smccc: Support SMCCC v1.3 SVE register saving hint") * a7c3acca5380 ("arm64: smccc: Save lr before calling __arm_smccc_sve_check()") ... leaving behind the ARM_SMCCC_VERSION_1_3 and ARM_SMCCC_1_3_SVE_HINT definitions, since these are simply definitions from the SMCCC specification, and the latter is used in KVM via ARM_SMCCC_CALL_HINTS. If we want to bring this back in future, we'll probably want to handle this logic in C where we can use all the usual FPSIMD/SVE/SME helper functions, and that'll likely require some rework of the SMCCC code and/or its callers.

This has been observed to result in warnings from do_sve_acc() where SVE traps are not expected while TIF_SVE is set: | if (test_and_set_thread_flag(TIF_SVE)) | WARN_ON(1); /* SVE access shouldn't have trapped */ Warnings of this form have been reported intermittently, e.g. https://lore.kernel.org/linux-arm-kernel/CA+G9fYtEGe_DhY2Ms7+L7NKsLYUomGsgq… https://lore.kernel.org/linux-arm-kernel/000000000000511e9a060ce5a45c@googl… The race can occur when the SVE trap handler is preempted before and after manipulating the saved FPSIMD/SVE state, starting and ending on the same CPU, e.g. | void do_sve_acc(unsigned long esr, struct pt_regs *regs) | { | // Trap on CPU 0 with TIF_SVE clear, SVE traps enabled | // task->fpsimd_cpu is 0. | // per_cpu_ptr(&fpsimd_last_state, 0) is task. | | ... | | // Preempted; migrated from CPU 0 to CPU 1. | // TIF_FOREIGN_FPSTATE is set. | | get_cpu_fpsimd_context(); | | if (test_and_set_thread_flag(TIF_SVE)) | WARN_ON(1); /* SVE access shouldn't have trapped */ | | sve_init_regs() { | if (!test_thread_flag(TIF_FOREIGN_FPSTATE)) { | ... | } else { | fpsimd_to_sve(current); | current->thread.fp_type = FP_STATE_SVE; | } | } | | put_cpu_fpsimd_context(); | | // Preempted; migrated from CPU 1 to CPU 0. | // task->fpsimd_cpu is still 0 | // If per_cpu_ptr(&fpsimd_last_state, 0) is still task then: | // - Stale HW state is reused (with SVE traps enabled) | // - TIF_FOREIGN_FPSTATE is cleared | // - A return to userspace skips HW state restore | } Fix the case where the state is not live and TIF_FOREIGN_FPSTATE is set by calling fpsimd_flush_task_state() to detach from the saved CPU state. This ensures that a subsequent context switch will not reuse the stale CPU state, and will instead set TIF_FOREIGN_FPSTATE, forcing the new state to be reloaded from memory prior to a return to userspace.
