Commit de1cbee4 which removed b_file_offset in favor of b_bn introduced a bug causing xfs_buf_allocate_memory() to overestimate the number of necessary pages. The problem is that xfs_buf_alloc() sets b_bn to -1 and thus effectively every buffer is straddling a page boundary which causes xfs_buf_allocate_memory() to allocate two pages and use vmalloc() for access which is unnecessary. Dave says xfs_buf_alloc() doesn't need to set b_bn to -1 anymore since the buffer is inserted into the cache only after being fully initialized now. So just make xfs_buf_alloc() fill in proper block number from the beginning.

An inode in the AIL can be flush locked and marked stale if a cluster free transaction occurs at the right time. The inode item is then marked as flushing, which causes xfsaild to spin and leaves the filesystem stalled. This is reproduced by running xfstests 273 in a loop for an extended period of time. Check for stale inodes before the flush lock. This marks the inode as pinned, leads to a log flush and allows the filesystem to proceed.

There is some concern that these iput()'s could be the final iputs and could induce lockups on people waiting on writeback.

add_all_parents did assume that path is already at a correct extent data item, which may not be true in case of data extents that were partly rewritten and splitted. We need to check if we're on a matching extent for every item and only for the ones after the first. The loop is changed to do this now. This patch also fixes a bug introduced with commit 3b127fd8 "Btrfs: remove obsolete btrfs_next_leaf call from __resolve_indirect_ref". The removal of next_leaf did sometimes result in slot==nritems when the above described case happens, and thus resulting in invalid values (e.g. wanted_obejctid) in add_all_parents (leading to missed backrefs or even crashes).

__alloc_memory_core_early() asks memblock for a range of memory then try to reserve it. If the reserved region array lacks space for the new range, memblock_double_array() is called to allocate more space for the array. If memblock is used to allocate memory for the new array it can end up using a range that overlaps with the range originally allocated in __alloc_memory_core_early(), leading to possible data corruption. With this patch memblock_double_array() now calls memblock_find_in_range() with a narrowed candidate range (in cases where the reserved.regions array is being doubled) so any memory allocated will not overlap with the original range that was being reserved. The range is narrowed by passing in the starting address and size of the previously allocated range. Then the range above the ending address is searched and if a candidate is not found, the range below the starting address is searched.

find_new_reaper() changes pid_ns->child_reaper, see add0d4df ("pid_ns: zap_pid_ns_processes: fix the ->child_reaper changing"). The original reason has gone away after the previous patch, ->children list must be empty after zap_pid_ns_processes(). However now we can not switch to init_pid_ns.child_reaper. __unhash_process() relies on the "->child_reaper == parent" check, but this check does not work if the last exiting task is also the child reaper. As Eric sugested, we can change __unhash_process() to use the parent's pid_ns and remove this code. Also, with this change we can move detach_pid(PIDTYPE_PID) back, where it was before the previous fix. Signed-off-by: NOleg Nesterov <oleg@redhat.com> Acked-by: N"Eric W.

由 Eric W. Biederman 提交于
Today we have a twofold bug. Sometimes release_task on pid == 1 in a pid namespace can run before other processes in a pid namespace have had release task called. With the result that pid_ns_release_proc can be called before the last proc_flus_task() is done using upid->ns->proc_mnt, resulting in the use of a stale pointer. This same set of circumstances can lead to waitpid(...) returning for a processes started with clone(CLONE_NEWPID) before the every process in the pid namespace has actually exited. To fix this modify zap_pid_ns_processess wait until all other processes in the pid namespace have exited, even EXIT_DEAD zombies. The delay_group_leader and related tests ensure that the thread gruop leader will be the last thread of a process group to be reaped, or to become EXIT_DEAD and self reap. With the change to zap_pid_ns_processes we get the guarantee that pid == 1 in a pid namespace will be the last task that release_task is called on. With pid == 1 being the last task to pass through release_task pid_ns_release_proc can no longer be called too early nor can wait return before all of the EXIT_DEAD tasks in a pid namespace have exited.
