Some resources controlled by cgroup aren't per-task and cgroup core allowing threads of a single thread_group to be in different cgroups forced memcg do explicitly find the group leader and use it. This is gonna be nasty when transitioning to unified hierarchy and in general we don't want and won't support granularity finer than processes. Mark "tasks" with CFTYPE_INSANE.

During a config change, propagate_exception() needs to traverse the subtree to update config on the subtree. Because such config updates need to allocate memory, it couldn't directly use cgroup_for_each_descendant_pre() which required the whole iteration to be contained in a single RCU read critical section. To work around the limitation, propagate_exception() built a linked list of descendant cgroups while read-locking RCU and then walked the list afterwards, which is safe as the whole iteration is protected by devcgroup_mutex. This works but is cumbersome. With the recent updates, cgroup iterators now allow dropping RCU read lock while iteration is in progress making this workaround no longer necessary. This patch replaces dev_cgroup->propagate_pending list and get_online_devcg() with direct cgroup_for_each_descendant_pre() walk.

This patch converts cgroup_for_each_child(), cgroup_next_descendant_pre/post() and thus cgroup_for_each_descendant_pre/post() to use cgroup_next_sibling() instead of manually dereferencing ->sibling.next. The only reason the iterators couldn't allow dropping RCU read lock while iteration is in progress was because they couldn't determine the next sibling safely once RCU read lock is dropped. Using cgroup_next_sibling() removes that problem and enables all iterators to allow dropping RCU read lock in the middle. Comments are updated accordingly. This makes the iterators easier to use and will simplify controllers. Note that @cgroup argument is renamed to @cgrp in cgroup_for_each_child() because it conflicts with "struct cgroup" used in the new macro body.

Currently, there's no easy way to find out the next sibling cgroup unless it's known that the current cgroup is accessed from the parent's children list in a single RCU critical section. This in turn forces all iterators to require whole iteration to be enclosed in a single RCU critical section, which sometimes is too restrictive. This patch implements cgroup_next_sibling() which can reliably determine the next sibling regardless of the state of the current cgroup as long as it's accessible. It currently is impossible to determine the next sibling after dropping RCU read lock because the cgroup being iterated could be removed anytime and if RCU read lock is dropped, nothing guarantess its ->sibling.next pointer is accessible. A removed cgroup would continue to point to its next sibling for RCU accesses but stop receiving updates from the sibling. IOW, the next sibling could be removed and then complete its grace period while RCU read lock is dropped, making it unsafe to dereference ->sibling.next after dropping and re-acquiring RCU read lock. This can be solved by adding a way to traverse to the next sibling without dereferencing ->sibling.next. This patch adds a monotonically increasing cgroup serial number, cgroup->serial_nr, which guarantees that all cgroup->children lists are kept in increasing serial_nr order. A new function, cgroup_next_sibling(), is implemented, which, if CGRP_REMOVED is not set on the current cgroup, follows ->sibling.next; otherwise, traverses the parent's ->children list until it sees a sibling with higher ->serial_nr. This allows the function to always return the next sibling regardless of the state of the current cgroup without adding overhead in the fast path. Further patches will update the iterators to use cgroup_next_sibling() so that they allow dropping RCU read lock and blocking while iteration is in progress which in turn will be used to simplify controllers. v2: Typo fix as per Serge.

由 Tejun Heo 提交于
When cgroup_next_descendant_pre() initiates a walk, it checks whether the subtree root doesn't have any children and if not returns NULL. Later code assumes that the subtree isn't empty. This is broken because the subtree may become empty inbetween, which can lead to the traversal escaping the subtree by walking to the sibling of the subtree root. There's no reason to have the early exit path. Remove it along with the later assumption that the subtree isn't empty. This simplifies the code a bit and fixes the subtle bug. While at it, fix the comment of cgroup_for_each_descendant_pre() which was incorrectly referring to ->css_offline() instead of ->css_online().

We're planning to converting hierarchy_ida to an idr and use it to look up hierarchy from its id. As we want the mapping to happen atomically with cgroupfs_root registration, this patch refactors hierarchy_id init / exit so that ida operations happen inside cgroup_[root_]mutex. * s/init_root_id()/cgroup_init_root_id()/ and make it return 0 or -errno like a normal function. * Move hierarchy_id initialization from cgroup_root_from_opts() into cgroup_mount() block where the root is confirmed to be used and being registered while holding both mutexes. * Split cgroup_drop_id() into cgroup_exit_root_id() and cgroup_free_root(), so that ID release can happen before dropping the mutexes in cgroup_kill_sb(). The latter expects hierarchy_id to be exited before being invoked. Signed-off-by: NTejun Heo <tj@kernel.org> Acked-by: NLi Zefan <lizefan@huawei.com>

cgroup_create_file() calls d_instantiate(), which may decide to look at the xattrs on the file. Smack always does this and SELinux can be configured to do so. But cgroup_add_file() didn't initialize xattrs before calling cgroup_create_file(), which finally leads to dereferencing NULL dentry->d_fsdata. This bug has been there since cgroup xattr was introduced.
