Subject: [GIT PULL] scheduler fixes
Date: Thu, 12 Jan 2023 15:25:31 +0100 [thread overview]
Message-ID: <Y8AYWxzqkoKQfgV9@gmail.com> (raw)
Linus,
Please pull the latest sched/urgent git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git sched-urgent-2023-01-12
# HEAD: 9a5418bc48babb313d2a62df29ebe21ce8c06c59 sched/core: Use kfree_rcu() in do_set_cpus_allowed()
- Fix scheduler frequency invariance bug related to overly long tickless periods
triggering an integer overflow and disabling the feature.
- Fix use-after-free bug in dup_user_cpus_ptr().
- Fix do_set_cpus_allowed() deadlock scenarios related to calling kfree() with
the pi_lock held. NOTE: the rcu_free() is the 'lazy' solution here - we looked
at patches to free the structure after the pi_lock got dropped, but that looked
quite a bit messier - and none of this is truly performance critical. We can
revisit this if it's too lazy of a solution ...
Thanks,
Ingo
