| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Device mapper sends an uevent when the device is suspended, using the function set_capacity_and_notify. However, this causes a race condition with udev. Udev skips scanning dm devices that are suspended. If we send an uevent while we are suspended, udev will be racing with device mapper resume code. If the device mapper resume code wins the race, udev will process the uevent after the device is resumed and it will properly scan the device. However, if udev wins the race, it will receive the uevent, find out that the dm device is suspended and skip scanning the device. This causes bugs such as systemd unmounting the device - see https://bugzilla.redhat.com/show_bug.cgi?id=2158628 This commit fixes this race. We replace the function set_capacity_and_notify with set_capacity, so that the uevent is not sent at this point. In do_resume, we detect if the capacity has changed and we pass a boolean variable need_resize_uevent to dm_kobject_uevent. dm_kobject_uevent adds "RESIZE=1" to the uevent if need_resize_uevent is set.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a DM device's table references itself, it will crash the kernel with an infinite recursion. Check for a self-reference in dm_get_device(). This is a quick check, but it won't catch more complicated circular references.

This is likely due to the asymmetric architecture of ARM64 processors. I've been unable to reproduce the results that claim WQ_UNBOUND gives a performance boost on x86-64. This flag is causing performance issues for multiple subsystems within Android. Notably, the same slowdown exists for decompression with EROFS. | open-prebuilt-camera | WQ_UNBOUND | ~WQ_UNBOUND | |-----------------------|------------|---------------| | verity wait time (us) | 11746 | 119 (-98%) | | erofs wait time (us) | 357805 | 174205 (-51%) | | sha256 ramdisk random read | WQ_UNBOUND | ~WQ_UNBOUND | |----------------------------|-----------=---|-------------| | arm64 (accelerated) | bw=42.4MiB/s | bw=212MiB/s | | arm64 (generic) | bw=16.5MiB/s | bw=48MiB/s | | x86_64 (generic) | bw=233MiB/s | bw=230MiB/s | Using a alloc_workqueue() @max_active arg of num_online_cpus() only made sense with WQ_UNBOUND. Switch the @max_active arg to 0 (aka default, which is 256 per-cpu). Also, eliminate 'wq_flags' since it really doesn't serve a purpose.

Fix the logic so that if fc->corrupt_bio_byte is non-zero, dm-flakey will not abort reads on writes with an error.

If we use dm-flakey with corrupt bio writes option, it will corrupt the content of the zero page which results in crashes of various userspace programs. Glibc assumes that memory returned by mmap is zeroed and it uses it for calloc implementation; if the newly mapped memory is not zeroed, calloc will return non-zeroed memory. Fix this bug by testing if the page is equal to ZERO_PAGE(0) and avoiding the corruption in this case. Cc: stable@vger.kernel.org Fixes: a00f5276e266 ("dm flakey: Properly corrupt multi-page bios.")

(Normal RCU CPU stall warnings have done this for many years) - Lazy-callback fixes to avoid delays during boot, suspend, and resume. (Note that lazy callbacks must be explicitly enabled, so this should not (yet) affect production use cases) - Make kfree_rcu() and friends take advantage of polled grace periods, thus reducing memory footprint by almost two orders of magnitude, admittedly on a microbenchmark This also begins the transition from kfree_rcu(p) to kfree_rcu_mightsleep(p). This transition was motivated by bugs where kfree_rcu(p), which can block, was typed instead of the intended kfree_rcu(p, rh) - SRCU updates, perhaps most notably fixing a bug that causes SRCU to fail when booted on a system with a non-zero boot CPU. This surprising situation actually happens for kdump kernels on the powerpc architecture This also adds an srcu_down_read() and srcu_up_read(), which act like srcu_read_lock() and srcu_read_unlock(), but allow an SRCU read-side critical section to be handed off from one task to another - Clean up the now-useless SRCU Kconfig option There are a few more commits that are not yet acked or pulled into maintainer trees, and these will be in a pull request for a later merge window - RCU-tasks updates, perhaps most notably these fixes: - A strange interaction between PID-namespace unshare and the RCU-tasks grace period that results in a low-probability but very real hang - A race between an RCU tasks rude grace period on a single-CPU system and CPU-hotplug addition of the second CPU that can result in a too-short grace period - A race between shrinking RCU tasks down to a single callback list and queuing a new callback to some other CPU, but where that queuing is delayed for more than an RCU grace period. This can result in that callback being stranded on the non-boot CPU - Torture-test updates and fixes - Torture-test scripting updates and fixes - Provide additional RCU CPU stall-warning information in kernels built with CONFIG_RCU_CPU_STALL_CPUTIME=y, and restore the full five-minute timeout limit for expedited RCU CPU stall warnings * tag 'rcu.2023.02.10a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu: (80 commits) rcu/kvfree: Add kvfree_rcu_mightsleep() and kfree_rcu_mightsleep() kernel/notifier: Remove CONFIG_SRCU init: Remove "select SRCU" fs/quota: Remove "select SRCU" fs/notify: Remove "select SRCU" fs/btrfs: Remove "select SRCU" fs: Remove CONFIG_SRCU drivers/pci/controller: Remove "select SRCU" drivers/net: Remove "select SRCU" drivers/md: Remove "select SRCU" drivers/hwtracing/stm: Remove "select SRCU" drivers/dax: Remove "select SRCU" drivers/base: Remove CONFIG_SRCU rcu: Disable laziness if lazy-tracking says so rcu: Track laziness during boot and suspend rcu: Remove redundant call to rcu_boost_kthread_setaffinity() rcu: Allow up to five minutes expedited RCU CPU stall-warning timeouts rcu: Align the output of RCU CPU stall warning messages rcu: Add RCU stall diagnosis information sched: Add helper nr_context_switches_cpu() ...
