psi: Fix uaf issue when psi trigger is destroyed while being polled
commit a06247c6804f1a7c86a2e5398a4c1f1db1471848 upstream.
With write operation on psi files replacing old trigger with a new one,
the lifetime of its waitqueue is totally arbitrary. Overwriting an
existing trigger causes its waitqueue to be freed and pending poll()
will stumble on trigger->event_wait which was destroyed.
Fix this by disallowing to redefine an existing psi trigger. If a write
operation is used on a file descriptor with an already existing psi
trigger, the operation will fail with EBUSY error.
Also bypass a check for psi_disabled in the psi_trigger_destroy as the
flag can be flipped after the trigger is created, leading to a memory
leak.

cgroup: Use open-time cgroup namespace for process migration perm checks
commit e57457641613fef0d147ede8bd6a3047df588b95 upstream.
cgroup process migration permission checks are performed at write time as
whether a given operation is allowed or not is dependent on the content of
the write - the PID. This currently uses current's cgroup namespace which is
a potential security weakness as it may allow scenarios where a less
privileged process tricks a more privileged one into writing into a fd that
it created.
This patch makes cgroup remember the cgroup namespace at the time of open
and uses it for migration permission checks instad of current's. Note that
this only applies to cgroup2 as cgroup1 doesn't have namespace support.
This also fixes a use-after-free bug on cgroupns reported in
https://lore.kernel.org/r/00000000000048c15c05d0083397@google.com
Note that backporting this fix also requires the preceding patch.

cgroup: Allocate cgroup_file_ctx for kernfs_open_file->priv
commit 0d2b5955b36250a9428c832664f2079cbf723bec upstream.
of->priv is currently used by each interface file implementation to store
private information. This patch collects the current two private data usages
into struct cgroup_file_ctx which is allocated and freed by the common path.
This allows generic private data which applies to multiple files, which will
be used to in the following patch.
Note that cgroup_procs iterator is now embedded as procs.iter in the new
cgroup_file_ctx so that it doesn't need to be allocated and freed
separately.
v2: union dropped from cgroup_file_ctx and the procs iterator is embedded in
cgroup_file_ctx as suggested by Linus.
v3: Michal pointed out that cgroup1's procs pidlist uses of->priv too.
Converted. Didn't change to embedded allocation as cgroup1 pidlists get
stored for caching.

the write - the PID. This currently uses current's credentials which is a
potential security weakness as it may allow scenarios where a less

This patch makes both cgroup2 and cgroup1 process migration interfaces to
use the credentials saved at the time of open (file->f_cred) instead of
current's.

It was caused by the fact that rebind_subsystem() disables
controllers to be rebound one by one. If more than one disabled
controllers are originally from the default hierarchy, it means that
cgroup_apply_control_disable() will be called multiple times for the
same default hierarchy. A controller may be killed by css_kill() in
the first round. In the second round, the killed controller may not be
completely dead yet leading to the warning.
To avoid this problem, we collect all the ssid's of controllers that
needed to be disabled from the default hierarchy and then disable them
in one go instead of one by one.

ANDROID: cgroup: Add android_rvh_cgroup_force_kthread_migration
In Android GKI, CONFIG_FAIR_GROUP_SCHED is enabled [1] to help
prioritize important work. Given that CPU shares of root cgroup
can't be changed, leaving the tasks inside root cgroup will give
them higher share compared to the other tasks inside important
cgroups. This is mitigated by moving all tasks inside root cgroup to
a different cgroup after Android is booted. However, there are many
kernel tasks stuck in the root cgroup after the boot.
It is possible to relax kernel threads and kworkers migrations under
certain scenarios. However the patch [2] posted at upstream is not
accepted. Hence add a restricted vendor hook to notify modules when a
kernel thread is requested for cgroup migration. The modules can relax
the restrictions forced by the kernel and allow the cgroup migration.

FROMGIT: cgroup: make per-cgroup pressure stall tracking configurable
PSI accounts stalls for each cgroup separately and aggregates it at each
level of the hierarchy. This causes additional overhead with psi_avgs_work
being called for each cgroup in the hierarchy. psi_avgs_work has been
highly optimized, however on systems with large number of cgroups the
overhead becomes noticeable.
Systems which use PSI only at the system level could avoid this overhead
if PSI can be configured to skip per-cgroup stall accounting.
Add "cgroup_disable=pressure" kernel command-line option to allow
requesting system-wide only pressure stall accounting. When set, it
keeps system-wide accounting under /proc/pressure/ but skips accounting
for individual cgroups and does not expose PSI nodes in cgroup hierarchy.

cgroup: introduce cgroup.kill
Introduce the cgroup.kill file. It does what it says on the tin and allows a caller to kill a cgroup by writing "1" into cgroup.kill. The file is available in non-root cgroups. Killing cgroups is a process directed operation, i.e. the whole thread-group is affected. Consequently trying to write to cgroup.kill in threaded cgroups will be rejected and EOPNOTSUPP returned. This behavior aligns with cgroup.procs where reads in threaded-cgroups are rejected with EOPNOTSUPP. The cgroup.kill file is write-only since killing a cgroup is an event not which makes it different from e.g. freezer where a cgroup transitions between the two states. As with all new cgroup features cgroup.kill is recursive by default. Killing a cgroup is protected against concurrent migrations through the cgroup mutex. To protect against forkbombs and to mitigate the effect of racing forks a new CGRP_KILL css set lock protected flag is introduced that is set prior to killing a cgroup and unset after the cgroup has been killed. We can then check in cgroup_post_fork() where we hold the css set lock already whether the cgroup is currently being killed. If so we send the child a SIGKILL signal immediately taking it down as soon as it returns to userspace. To make the killing of the child semantically clean it is killed after all cgroup attachment operations have been finalized. There are various use-cases of this interface: - Containers usually have a conservative layout where each container usually has a delegated cgroup. For such layouts there is a 1:1 mapping between container and cgroup. If the container in addition uses a separate pid namespace then killing a container usually becomes a simple kill -9 <container-init-pid> from an ancestor pid namespace. However, there are quite a few scenarios where that isn't true. For example, there are containers that share the cgroup with other processes on purpose that are supposed to be bound to the lifetime of the container but are not in the same pidns of the container. Containers that are in a delegated cgroup but share the pid namespace with the host or other containers. - Service managers such as systemd use cgroups to group and organize processes belonging to a service. They usually rely on a recursive algorithm now to kill a service. With cgroup.kill this becomes a simple write to cgroup.kill. - Userspace OOM implementations can make good use of this feature to efficiently take down whole cgroups quickly. - The kill program can gain a new kill --cgroup /sys/fs/cgroup/delegated flag to take down cgroups. A few observations about the semantics: - If parent and child are in the same cgroup and CLONE_INTO_CGROUP is not specified we are not taking cgroup mutex meaning the cgroup can be killed while a process in that cgroup is forking. If the kill request happens right before cgroup_can_fork() and before the parent grabs its siglock the parent is guaranteed to see the pending SIGKILL. In addition we perform another check in cgroup_post_fork() whether the cgroup is being killed and is so take down the child (see above). This is robust enough and protects gainst forkbombs. If userspace really really wants to have stricter protection the simple solution would be to grab the write side of the cgroup threadgroup rwsem which will force all ongoing forks to complete before killing starts. We concluded that this is not necessary as the semantics for concurrent forking should simply align with freezer where a similar check as cgroup_post_fork() is performed. For all other cases CLONE_INTO_CGROUP is required. In this case we will grab the cgroup mutex so the cgroup can't be killed while we fork. Once we're done with the fork and have dropped cgroup mutex we are visible and will be found by any subsequent kill request. - We obviously don't kill kthreads. This means a cgroup that has a kthread will not become empty after killing and consequently no unpopulated event will be generated. The assumption is that kthreads should be in the root cgroup only anyway so this is not an issue. - We skip killing tasks that already have pending fatal signals. - Freezer doesn't care about tasks in different pid namespaces, i.e. if you have two tasks in different pid namespaces the cgroup would still be frozen. The cgroup.kill mechanism consequently behaves the same way, i.e. we kill all processes and ignore in which pid namespace they exist. - If the caller is located in a cgroup that is killed the caller will obviously be killed as well.

cgroup: rstat: support cgroup1
Rstat currently only supports the default hierarchy in cgroup2. In order to replace memcg's private stats infrastructure - used in both cgroup1 and cgroup2 - with rstat, the latter needs to support cgroup1. The initialization and destruction callbacks for regular cgroups are already in place. Remove the cgroup_on_dfl() guards to handle cgroup1. The initialization of the root cgroup is currently hardcoded to only handle cgrp_dfl_root.cgrp. Move those callbacks to cgroup_setup_root() and cgroup_destroy_root() to handle the default root as well as the various cgroup1 roots we may set up during mounting. The linking of css to cgroups happens in code shared between cgroup1 and cgroup2 as well. Simply remove the cgroup_on_dfl() guard. Linkage of the root css to the root cgroup is a bit trickier: per default, the root css of a subsystem controller belongs to the default hierarchy (i.e. the cgroup2 root). When a controller is mounted in its cgroup1 version, the root css is stolen and moved to the cgroup1 root; on unmount, the css moves back to the default hierarchy. Annotate rebind_subsystems() to move the root css linkage along between roots.

Merge tag 'idmapped-mounts-v5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux
Pull idmapped mounts from Christian Brauner:
"This introduces idmapped mounts which has been in the making for some
time. Simply put, different mounts can expose the same file or
directory with different ownership. This initial implementation comes
with ports for fat, ext4 and with Christoph's port for xfs with more
filesystems being actively worked on by independent people and
maintainers.
Idmapping mounts handle a wide range of long standing use-cases. Here
are just a few:
- Idmapped mounts make it possible to easily share files between
multiple users or multiple machines especially in complex
scenarios. For example, idmapped mounts will be used in the
implementation of portable home directories in
systemd-homed.service(8) where they allow users to move their home
directory to an external storage device and use it on multiple
computers where they are assigned different uids and gids. This
effectively makes it possible to assign random uids and gids at
login time.
- It is possible to share files from the host with unprivileged
containers without having to change ownership permanently through
chown(2).
- It is possible to idmap a container's rootfs and without having to
mangle every file. For example, Chromebooks use it to share the
user's Download folder with their unprivileged containers in their
Linux subsystem.
- It is possible to share files between containers with
non-overlapping idmappings.
- Filesystem that lack a proper concept of ownership such as fat can
use idmapped mounts to implement discretionary access (DAC)
permission checking.
- They allow users to efficiently changing ownership on a per-mount
basis without having to (recursively) chown(2) all files. In
contrast to chown (2) changing ownership of large sets of files is
instantenous with idmapped mounts. This is especially useful when
ownership of a whole root filesystem of a virtual machine or
container is changed. With idmapped mounts a single syscall
mount_setattr syscall will be sufficient to change the ownership of
all files.
- Idmapped mounts always take the current ownership into account as
idmappings specify what a given uid or gid is supposed to be mapped
to. This contrasts with the chown(2) syscall which cannot by itself
take the current ownership of the files it changes into account. It
simply changes the ownership to the specified uid and gid. This is
especially problematic when recursively chown(2)ing a large set of
files which is commong with the aforementioned portable home
directory and container and vm scenario.
- Idmapped mounts allow to change ownership locally, restricting it
to specific mounts, and temporarily as the ownership changes only
apply as long as the mount exists.
Several userspace projects have either already put up patches and
pull-requests for this feature or will do so should you decide to pull
this:
- systemd: In a wide variety of scenarios but especially right away
in their implementation of portable home directories.
https://systemd.io/HOME_DIRECTORY/
- container runtimes: containerd, runC, LXD:To share data between
host and unprivileged containers, unprivileged and privileged
containers, etc. The pull request for idmapped mounts support in
containerd, the default Kubernetes runtime is already up for quite
a while now: https://github.com/containerd/containerd/pull/4734
- The virtio-fs developers and several users have expressed interest
in using this feature with virtual machines once virtio-fs is
ported.
- ChromeOS: Sharing host-directories with unprivileged containers.
I've tightly synced with all those projects and all of those listed
here have also expressed their need/desire for this feature on the
mailing list. For more info on how people use this there's a bunch of
talks about this too. Here's just two recent ones:
https://www.cncf.io/wp-content/uploads/2020/12/Rootless-Containers-in-Gitpod.pdf
https://fosdem.org/2021/schedule/event/containers_idmap/
This comes with an extensive xfstests suite covering both ext4 and
xfs:
https://git.kernel.org/brauner/xfstests-dev/h/idmapped_mounts
It covers truncation, creation, opening, xattrs, vfscaps, setid
execution, setgid inheritance and more both with idmapped and
non-idmapped mounts. It already helped to discover an unrelated xfs
setgid inheritance bug which has since been fixed in mainline. It will
be sent for inclusion with the xfstests project should you decide to
merge this.
In order to support per-mount idmappings vfsmounts are marked with
user namespaces. The idmapping of the user namespace will be used to
map the ids of vfs objects when they are accessed through that mount.
By default all vfsmounts are marked with the initial user namespace.
The initial user namespace is used to indicate that a mount is not
idmapped. All operations behave as before and this is verified in the
testsuite.
Based on prior discussions we want to attach the whole user namespace
and not just a dedicated idmapping struct. This allows us to reuse all
the helpers that already exist for dealing with idmappings instead of
introducing a whole new range of helpers. In addition, if we decide in
the future that we are confident enough to enable unprivileged users
to setup idmapped mounts the permission checking can take into account
whether the caller is privileged in the user namespace the mount is
currently marked with.
The user namespace the mount will be marked with can be specified by
passing a file descriptor refering to the user namespace as an
argument to the new mount_setattr() syscall together with the new
MOUNT_ATTR_IDMAP flag. The system call follows the openat2() pattern
of extensibility.
The following conditions must be met in order to create an idmapped
mount:
- The caller must currently have the CAP_SYS_ADMIN capability in the
user namespace the underlying filesystem has been mounted in.
- The underlying filesystem must support idmapped mounts.
- The mount must not already be idmapped. This also implies that the
idmapping of a mount cannot be altered once it has been idmapped.
- The mount must be a detached/anonymous mount, i.e. it must have
been created by calling open_tree() with the OPEN_TREE_CLONE flag
and it must not already have been visible in the filesystem.
The last two points guarantee easier semantics for userspace and the
kernel and make the implementation significantly simpler.
By default vfsmounts are marked with the initial user namespace and no
behavioral or performance changes are observed.

namei: make permission helpers idmapped mount aware
The two helpers inode_permission() and generic_permission() are used by the vfs to perform basic permission checking by verifying that the caller is privileged over an inode. In order to handle idmapped mounts we extend the two helpers with an additional user namespace argument. On idmapped mounts the two helpers will make sure to map the inode according to the mount's user namespace and then peform identical permission checks to inode_permission() and generic_permission(). If the initial user namespace is passed nothing changes so non-idmapped mounts will see identical behavior as before.

cgroup: remove obsoleted broken_hierarchy and warned_broken_hierarchy
With the deprecation of the non-hierarchical mode of the memory controller there are no more examples of broken hierarchies left. Let's remove the cgroup core code which was supposed to print warnings about creating of broken hierarchies.

mm: memcg: deprecate the non-hierarchical mode
Patch series "mm: memcg: deprecate cgroup v1 non-hierarchical mode", v1. The non-hierarchical cgroup v1 mode is a legacy of early days of the memory controller and doesn't bring any value today. However, it complicates the code and creates many edge cases all over the memory controller code. It's a good time to deprecate it completely. This patchset removes the internal logic, adjusts the user interface and updates the documentation. The alt patch removes some bits of the cgroup core code, which become obsolete. Michal Hocko said: "All that we know today is that we have a warning in place to complain loudly when somebody relies on use_hierarchy=0 with a deeper hierarchy. For all those years we have seen _zero_ reports that would describe a sensible usecase. Moreover we (SUSE) have backported this warning into old distribution kernels (since 3.0 based kernels) to extend the coverage and didn't hear even for users who adopt new kernels only very slowly. The only report we have seen so far was a LTP test suite which doesn't really reflect any real life usecase" This patch (of 3): The non-hierarchical cgroup v1 mode is a legacy of early days of the memory controller and doesn't bring any value today. However, it complicates the code and creates many edge cases all over the memory controller code. It's a good time to deprecate it completely. Functionally this patch enabled is by default for all cgroups and forbids switching it off. Nothing changes if cgroup v2 is used: hierarchical mode was enforced from scratch. To protect the ABI memory.use_hierarchy interface is preserved with a limited functionality: reading always returns "1", writing of "1" passes silently, writing of any other value fails with -EINVAL and a warning to dmesg (on the first occasion).
