BACKPORT: cgroup: Fix threadgroup_rwsem <-> cpus_read_lock() deadlock
Bringing up a CPU may involve creating and destroying tasks which requires read-locking threadgroup_rwsem, so threadgroup_rwsem nests inside cpus_read_lock(). However, cpuset's ->attach(), which may be called with thredagroup_rwsem write-locked, also wants to disable CPU hotplug and acquires cpus_read_lock(), leading to a deadlock. Fix it by guaranteeing that ->attach() is always called with CPU hotplug disabled and removing cpus_read_lock() call from cpuset_attach().

cgroup/cpuset: Remove cpus_allowed/mems_allowed setup in cpuset_init_smp()
commit 2685027fca387b602ae565bff17895188b803988 upstream. There are 3 places where the cpu and node masks of the top cpuset can be initialized in the order they are executed: 1) start_kernel -> cpuset_init() 2) start_kernel -> cgroup_init() -> cpuset_bind() 3) kernel_init_freeable() -> do_basic_setup() -> cpuset_init_smp() The first cpuset_init() call just sets all the bits in the masks. The second cpuset_bind() call sets cpus_allowed and mems_allowed to the default v2 values. The third cpuset_init_smp() call sets them back to v1 values. For systems with cgroup v2 setup, cpuset_bind() is called once. As a result, cpu and memory node hot add may fail to update the cpu and node masks of the top cpuset to include the newly added cpu or node in a cgroup v2 environment. For systems with cgroup v1 setup, cpuset_bind() is called again by rebind_subsystem() when the v1 cpuset filesystem is mounted as shown in the dmesg log below with an instrumented kernel. [ 2.609781] cpuset_bind() called - v2 = 1 [ 3.079473] cpuset_init_smp() called [ 7.103710] cpuset_bind() called - v2 = 0 smp_init() is called after the first two init functions. So we don't have a complete list of active cpus and memory nodes until later in cpuset_init_smp() which is the right time to set up effective_cpus and effective_mems. To fix this cgroup v2 mask setup problem, the potentially incorrect cpus_allowed & mems_allowed setting in cpuset_init_smp() are removed. For cgroup v2 systems, the initial cpuset_bind() call will set the masks correctly. For cgroup v1 systems, the second call to cpuset_bind() will do the right setup. cc: stable@vger.kernel.org Signed-off-by: Waiman Long <longman@redhat.com> Tested-by: Feng Tang <feng.tang@intel.com> Reviewed-by: Michal Koutný <mkoutny@suse.com> Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |

cgroup/cpuset: Fix a race between cpuset_attach() and cpu hotplug
commit 05c7b7a92cc87ff8d7fde189d0fade250697573c upstream.
As previously discussed(https://lkml.org/lkml/2022/1/20/51),
cpuset_attach() is affected with similar cpu hotplug race,
as follow scenario:
cpuset_attach() cpu hotplug
--------------------------- ----------------------
down_write(cpuset_rwsem)
guarantee_online_cpus() // (load cpus_attach)
sched_cpu_deactivate
set_cpu_active()
// will change cpu_active_mask
set_cpus_allowed_ptr(cpus_attach)
__set_cpus_allowed_ptr_locked()
// (if the intersection of cpus_attach and
cpu_active_mask is empty, will return -EINVAL)
up_write(cpuset_rwsem)
To avoid races such as described above, protect cpuset_attach() call
with cpu_hotplug_lock.

cgroup/cpuset: Fix "suspicious RCU usage" lockdep warning
commit 2bdfd2825c9662463371e6691b1a794e97fa36b4 upstream.
It was found that a "suspicious RCU usage" lockdep warning was issued
with the rcu_read_lock() call in update_sibling_cpumasks(). It is
because the update_cpumasks_hier() function may sleep. So we have
to release the RCU lock, call update_cpumasks_hier() and reacquire
it afterward.
Also add a percpu_rwsem_assert_held() in update_sibling_cpumasks()
instead of stating that in the comment.

cpuset: Fix the bug that subpart_cpus updated wrongly in update_cpumask()
commit c80d401c52a2d1baf2a5afeb06f0ffe678e56d23 upstream.
subparts_cpus should be limited as a subset of cpus_allowed, but it is
updated wrongly by using cpumask_andnot(). Use cpumask_and() instead to
fix it.

ANDROID: cpuhp/pause: schedule cpu_hotplug_work on resume cpu
Resume cpu need to run cpuset_hotplug_workfn which need take
about several milliseconds, and even more if the system have
more tasks.
This isn't suitable to run in the main task context of resume
cpu.
Due to the cpu which is resuming only have active mask,
but still not rebuild sched domain, make this slow
work run on resuming cpu can not take extra overload to
previous active cpus.

cgroup/cpuset: Fix a partition bug with hotplug
[ Upstream commit 15d428e6fe77fffc3f4fff923336036f5496ef17 ]
In cpuset_hotplug_workfn(), the detection of whether the cpu list
has been changed is done by comparing the effective cpus of the top
cpuset with the cpu_active_mask. However, in the rare case that just
all the CPUs in the subparts_cpus are offlined, the detection fails
and the partition states are not updated correctly. Fix it by forcing
the cpus_updated flag to true in this particular case.

BACKPORT: FROMLIST: cpuset: Honour task_cpu_possible_mask() in guarantee_online_cpus()
Asymmetric systems may not offer the same level of userspace ISA support across all CPUs, meaning that some applications cannot be executed by some CPUs. As a concrete example, upcoming arm64 big.LITTLE designs do not feature support for 32-bit applications on both clusters. Modify guarantee_online_cpus() to take task_cpu_possible_mask() into account when trying to find a suitable set of online CPUs for a given task. This will avoid passing an invalid mask to set_cpus_allowed_ptr() during ->attach() and will subsequently allow the cpuset hierarchy to be taken into account when forcefully overriding the affinity mask for a task which requires migration to a compatible CPU.

FROMLIST: cpuset: Don't use the cpu_possible_mask as a last resort for cgroup v1
If the scheduler cannot find an allowed CPU for a task, cpuset_cpus_allowed_fallback() will widen the affinity to cpu_possible_mask if cgroup v1 is in use. In preparation for allowing architectures to provide their own fallback mask, just return early if we're not using cgroup v2 and allow select_fallback_rq() to figure out the mask by itself.

cpuset: fix race between hotplug work and later CPU offline
commit 406100f3da08066c00105165db8520bbc7694a36 upstream.
One of our machines keeled over trying to rebuild the scheduler domains.
Mainline produces the same splat:
BUG: unable to handle page fault for address: 0000607f820054db
CPU: 2 PID: 149 Comm: kworker/1:1 Not tainted 5.10.0-rc1-master+ #6
Workqueue: events cpuset_hotplug_workfn
RIP: build_sched_domains
Call Trace:
partition_sched_domains_locked
rebuild_sched_domains_locked
cpuset_hotplug_workfn
It happens with cgroup2 and exclusive cpusets only. This reproducer
triggers it on an 8-cpu vm and works most effectively with no
preexisting child cgroups:
cd $UNIFIED_ROOT
mkdir cg1
echo 4-7 > cg1/cpuset.cpus
echo root > cg1/cpuset.cpus.partition
# with smt/control reading 'on',
echo off > /sys/devices/system/cpu/smt/control
RIP maps to
sd->shared = *per_cpu_ptr(sdd->sds, sd_id);
from sd_init(). sd_id is calculated earlier in the same function:
cpumask_and(sched_domain_span(sd), cpu_map, tl->mask(cpu));
sd_id = cpumask_first(sched_domain_span(sd));
tl->mask(cpu), which reads cpu_sibling_map on x86, returns an empty mask
and so cpumask_first() returns >= nr_cpu_ids, which leads to the bogus
value from per_cpu_ptr() above.
The problem is a race between cpuset_hotplug_workfn() and a later
offline of CPU N. cpuset_hotplug_workfn() updates the effective masks
when N is still online, the offline clears N from cpu_sibling_map, and
then the worker uses the stale effective masks that still have N to
generate the scheduling domains, leading the worker to read
N's empty cpu_sibling_map in sd_init().
rebuild_sched_domains_locked() prevented the race during the cgroup2
cpuset series up until the Fixes commit changed its check. Make the
check more robust so that it can detect an offline CPU in any exclusive
cpuset's effective mask, not just the top one.
Fixes:

ANDROID: cpu/hotplug: rebuild sched domains immediately
In the resume_cpus() path, cpus cannot be taken advantage of until the cpus write lock is acquired, and cpus are activated and domains rebuilt. This can incurr significant delay in the unpause operation. Additionally, if scheduled through the kworker thread, the wait time for rebuilding sched domains becomes large due to a busy system that can prevent the kworker from executing. Activate the cpus and call the cpuset_hotplug_workfn directly within resume_cpus prior to getting the cpus write lock, thereby eliminating delays associated with scheduling this activity.

ANDROID: cpuset: Make cpusets restore on hotplug
This deliberately changes the behavior of the per-cpuset
cpus file to not be effected by hotplug. When a cpu is offlined,
it will be removed from the cpuset/cpus file. When a cpu is onlined,
if the cpuset originally requested that that cpu was part of the cpuset,
that cpu will be restored to the cpuset. The cpus files still
have to be hierachical, but the ranges no longer have to be out of
the currently online cpus, just the physically present cpus.

The faulty line in question is:
cap = arch_scale_cpu_capacity(cpumask_first(cpu_map));
and we're not checking the return value against nr_cpu_ids (we shouldn't
have to!), which leads to the above.
Prevent generate_sched_domains() from returning empty cpumasks, and add
some assertion in build_sched_domains() to scream bloody murder if it
happens again.
The above splat was obtained on my Juno r0 with the following reproducer:
$ cgcreate -g cpuset:asym
$ cgset -r cpuset.cpus=0-3 asym
$ cgset -r cpuset.mems=0 asym
$ cgset -r cpuset.cpu_exclusive=1 asym
$ cgcreate -g cpuset:smp
$ cgset -r cpuset.cpus=4-5 smp

$ cgset -r cpuset.sched_load_balance=0 .

cgroup: remove cgroup_enable_task_cg_lists() optimization
cgroup_enable_task_cg_lists() is used to lazyily initialize task cgroup associations on the first use to reduce fork / exit overheads on systems which don't use cgroup. Unfortunately, locking around it has never been actually correct and its value is dubious given how the vast majority of systems use cgroup right away from boot. This patch removes the optimization. For now, replace the cg_list based branches with WARN_ON_ONCE()'s to be on the safe side. We can simplify the logic further in the future.

sched/core: Prevent race condition between cpuset and __sched_setscheduler()
No synchronisation mechanism exists between the cpuset subsystem and calls to function __sched_setscheduler(). As such, it is possible that new root domains are created on the cpuset side while a deadline acceptance test is carried out in __sched_setscheduler(), leading to a potential oversell of CPU bandwidth. Grab cpuset_rwsem read lock from core scheduler, so to prevent situations such as the one described above from happening. The only exception is normalize_rt_tasks() which needs to work under tasklist_lock and can't therefore grab cpuset_rwsem. We are fine with this, as this function is only called by sysrq and, if that gets triggered, DEADLINE guarantees are already gone out of the window anyway.

cgroup/cpuset: Change cpuset_rwsem and hotplug lock order
cpuset_rwsem is going to be acquired from sched_setscheduler() with a following patch. There are however paths (e.g., spawn_ksoftirqd) in which sched_scheduler() is eventually called while holding hotplug lock; this creates a dependecy between hotplug lock (to be always acquired first) and cpuset_rwsem (to be always acquired after hotplug lock). Fix paths which currently take the two locks in the wrong order (after a following patch is applied).

cgroup/cpuset: Convert cpuset_mutex to percpu_rwsem
Holding cpuset_mutex means that cpusets are stable (only the holder can make changes) and this is required for fixing a synchronization issue between cpusets and scheduler core. However, grabbing cpuset_mutex from setscheduler() hotpath (as implemented in a later patch) is a no-go, as it would create a bottleneck for tasks concurrently calling setscheduler(). Convert cpuset_mutex to be a percpu_rwsem (cpuset_rwsem), so that setscheduler() will then be able to read lock it and avoid concurrency issues.

cpusets: Rebuild root domain deadline accounting information
When the topology of root domains is modified by CPUset or CPUhotplug operations information about the current deadline bandwidth held in the root domain is lost. This patch addresses the issue by recalculating the lost deadline bandwidth information by circling through the deadline tasks held in CPUsets and adding their current load to the root domain they are associated with.
