[PATCH v2] Avoid deadlock for recursive I/O on dm-thin when used as swap

by Coly Li

This is an alrady known issue that dm-thin volume cannot be used as swap, otherwise a deadlock may happen when dm-thin internal memory demond triggers swap I/O on the dm-thin volume itself. Thanks to Mikulas Patocka for commit a666e5c05e7c ("dm: fix deadlock when swapping to encrypted device"), this method can also be used for dm-thin to avoid the recursive I/O when it is used as swap. This patch just simply sets ti->limit_swap_bios by tree in pool_ctr() and thin_ctr(), other important stuffs are already done by Patocka in the above mentioned commit. In my test, I create a dm-thin volume /dev/vg/swap and use it as swap device. Then I run fio on another dm-thin volume /dev/vg/main and use large --blocksize to trigger swap I/O onto /dev/vg/swap. The following fio command line is used in my test, fio --name recursive-swap-io --lockmem 1 --iodepth 128 \ --ioengine libaio --filename /dev/vg/main --rw randrw \ --blocksize 1M --numjobs 32 --time_based --runtime=12h Without the patch, the whole system can be locked up within 15 seconds. With this patch, there is no any deadlock or hang task observed after 2 hours fio running. Further more, I change --blocksize from 1M to 128M, around 30 seconds after fio running, no I/O rate displayed by fio, and the out-of-memory killer message shows up in kernel message. After around 20 minutes all fio processes are killed and the whole system backs to be alive. This is exactly what is expected when recursive I/O happens on dm-thin volume when it is used as swap. Note: this change depends on commit a666e5c05e7c ("dm: fix deadlock when swapping to encrypted device") Signed-off-by: Coly Li <colyli(a)suse.de> Cc: Mikulas Patocka <mpatocka(a)redhat.com> Cc: Mike Snitzer <snitzer(a)kernel.org> Cc: stable(a)vger.kernel.org --- Changelog, v2: fix typo in commit log. v1: initial version. drivers/md/dm-thin.c | 2 ++ 1 file changed, 2 insertions(+) --- a/drivers/md/dm-thin.c +++ b/drivers/md/dm-thin.c @@ -3355,6 +3355,7 @@ static int pool_ctr(struct dm_target *ti pt->low_water_blocks = low_water_blocks; pt->adjusted_pf = pt->requested_pf = pf; ti->num_flush_bios = 1; + ti->limit_swap_bios = true; /* * Only need to enable discards if the pool should pass @@ -4233,6 +4234,7 @@ static int thin_ctr(struct dm_target *ti goto bad; ti->num_flush_bios = 1; + ti->limit_swap_bios = true; ti->flush_supported = true; ti->accounts_remapped_io = true; ti->per_io_data_size = sizeof(struct dm_thin_endio_hook);

Please backport commit a449dfbfc089 (PM: sleep: Avoid using pr_cont() in the tasks freezing code)

by Paul Menzel

Dear Linux folks, It’d be great if you could apply the commit below [1], present in Linux since 6.2-rc1, to at least the Linux 6.1 LTS series. commit a449dfbfc0894676ad0aa1873383265047529e3a Author: Rafael J. Wysocki <rafael.j.wysocki(a)intel.com> Date: Thu Dec 1 19:33:09 2022 +0100 PM: sleep: Avoid using pr_cont() in the tasks freezing code Using pr_cont() in the tasks freezing code related to system-wide suspend and hibernation is problematic, because the continuation messages printed there are susceptible to interspersing with other unrelated messages which results in output that is hard to understand. Address this issue by modifying try_to_freeze_tasks() to print messages that don't require continuations and adjusting its callers accordingly.

[PATCH v3 1/2] x86/speculation: Allow enabling STIBP with legacy IBRS

by KP Singh

When plain IBRS is enabled (not enhanced IBRS), the logic in spectre_v2_user_select_mitigation() determines that STIBP is not needed. The IBRS bit implicitly protects against cross-thread branch target injection. However, with legacy IBRS, the IBRS bit is cleared on returning to userspace for performance reasons which leaves userspace threads vulnerable to cross-thread branch target injection against which STIBP protects. Exclude IBRS from the spectre_v2_in_ibrs_mode() check to allow for enabling STIBP (through seccomp/prctl() by default or always-on, if selected by spectre_v2_user kernel cmdline parameter).
