2024-03-02dm-verity: Convert from tasklet to BH workqueueTejun Heo
The only generic interface to execute asynchronously in the BH context is tasklet; however, it's marked deprecated and has some design flaws. To replace tasklets, BH workqueue support was recently added. A BH workqueue behaves similarly to regular workqueues except that the queued work items are executed in the BH context. This commit converts dm-verity from tasklet to BH workqueue. It backfills tasklet code that was removed with commit 0a9bab391e33 ("dm-crypt, dm-verity: disable tasklets") and tweaks to use BH workqueue (and does some renaming). This is a minimal conversion which doesn't rename the related names including the "try_verify_in_tasklet" option. If this patch is applied, a follow-up patch would be necessary. I couldn't decide whether the option name would need to be updated too.

This commit converts dm-crypt from tasklet to BH workqueue. It backfills tasklet code that was removed with commit 0a9bab391e33 ("dm-crypt, dm-verity: disable tasklets") and tweaks to use BH workqueue. Like a regular workqueue, a BH workqueue allows freeing the currently executing work item. Converting from tasklet to BH workqueue removes the need for deferring bio_endio() again to a work item, which was buggy anyway. I tested this lightly with "--perf-no_read_workqueue --perf-no_write_workqueue" + some code modifications, but would really -appreciate if someone who knows the code base better could take a look.

2024-03-02dt-bindings: pwm: amlogic: Add a new binding for meson8 pwm typesJerome Brunet
The binding that is used up to now describe which input the PWM channel multiplexer should pick among its possible parents, which are hardcoded in the driver. This isn't a good binding in the sense that it should describe hardware but not usage. Add a new binding deprecating the old one that uses clocks in a better way and how clocks are usually used today: The list of clocks describe the inputs of the PWM block as they are realised in hardware. So deprecate the old bindings and introduce a compatible per SoC family to replace these.

2024-03-02dt-bindings: pwm: amlogic: fix s4 bindingsJerome Brunet
s4 has been added to the compatible list while converting the Amlogic PWM binding documentation from txt to yaml. However, on the s4, the clock bindings have different meaning compared to the previous SoCs. On the previous SoCs the clock bindings used to describe which input the PWM channel multiplexer should pick among its possible parents. This is very much tied to the driver implementation, instead of describing the HW for what it is. When support for the Amlogic PWM was first added, how to deal with clocks through DT was not as clear as it nowadays. The Linux driver now ignores this DT setting, but still relies on the hard-coded list of clock sources. On the s4, the input multiplexer is gone. The clock bindings actually describe the clock as it exists, not a setting. The property has a different meaning, even if it is still 2 clocks and it would pass the check when support is actually added. Also the s4 cannot work if the clocks are not provided, so the property is no longer optional. Finally, for once it makes sense to see the input as being numbered somehow. No need to bother with clock-names on the s4 type of PWM.

2024-03-01net/mlx5e: Fix MACsec state loss upon state update in offload pathEmeel Hakim
The packet number attribute of the SA is incremented by the device rather than the software stack when enabling hardware offload. Because the packet number attribute is managed by the hardware, the software has no insight into the value of the packet number attribute actually written by the device. Previously when MACsec offload was enabled, the hardware object for handling the offload was destroyed when the SA was disabled. Re-enabling the SA would lead to a new hardware object being instantiated. This new hardware object would not have any recollection of the correct packet number for the SA. Instead, destroy the flow steering rule when deactivating the SA and recreate it upon reactivation, preserving the original hardware object.

2024-03-01cpufreq: Don't unregister cpufreq cooling on CPU hotplugViresh Kumar
Offlining a CPU and bringing it back online is a common operation and it happens frequently during system suspend/resume, where the non-boot CPUs are hotplugged out during suspend and brought back at resume. The cpufreq core already tries to make this path as fast as possible as the changes are only temporary in nature and full cleanup of resources isn't required in this case. For example the drivers can implement online()/offline() callbacks to avoid a lot of tear down of resources. On similar lines, there is no need to unregister the cpufreq cooling device during suspend / resume, but only while the policy is getting removed. Moreover, unregistering the cpufreq cooling device is resulting in an unwanted outcome, where the system suspend is eventually aborted in the process. Currently, during system suspend the cpufreq core unregisters the cooling device, which in turn removes a kobject using device_del() and that generates a notification to the userspace via uevent broadcast. This causes system suspend to abort in some setups. This was also earlier reported (indirectly) by Roman [1]. Maybe there is another way around to fixing that problem properly, but this change makes sense anyways. Move the registering and unregistering of the cooling device to policy creation and removal times onlyy.

2024-03-01sched/idle: Conditionally handle tick broadcast in default_idle_call()Thomas Gleixner
The x86 architecture has an idle routine for AMD CPUs which are affected by erratum 400. On the affected CPUs the local APIC timer stops in the C1E halt state. It therefore requires tick broadcasting. The invocation of tick_broadcast_enter()/exit() from this function violates the RCU constraints because it can end up in lockdep or tracing, which rightfully triggers a warning. tick_broadcast_enter()/exit() must be invoked before ct_cpuidle_enter() and after ct_cpuidle_exit() in default_idle_call(). Add a static branch conditional invocation of tick_broadcast_enter()/exit() into this function to allow X86 to replace the AMD specific idle code. It's guarded by a config switch which will be selected by x86. Otherwise it's a NOOP.

2024-03-01tomoyo: fix UAF write bug in tomoyo_write_control()Tetsuo Handa
Since tomoyo_write_control() updates head->write_buf when write() of long lines is requested, we need to fetch head->write_buf after head->io_sem is held. Otherwise, concurrent write() requests can cause use-after-free-write and double-free problems.

2024-03-01x86/e820: Don't reserve SETUP_RNG_SEED in e820Jiri Bohac
SETUP_RNG_SEED in setup_data is supplied by kexec and should not be reserved in the e820 map. Doing so reserves 16 bytes of RAM when booting with kexec. (16 bytes because data->len is zeroed by parse_setup_data so only sizeof(setup_data) is reserved.) When kexec is used repeatedly, each boot adds two entries in the kexec-provided e820 map as the 16-byte range splits a larger range of usable memory. Eventually all of the 128 available entries get used up. The next split will result in losing usable memory as the new entries cannot be added to the e820 map.
