Pull AFS callback promise fixes from David Howells: "This series fixes a bunch of problems in callback promise handling, where a callback promise indicates a promise on the part of the server to notify the client in the event of some sort of change to a file or volume. In the event of a break, the client has to go and refetch the client status from the server and discard any cached permission information as the ACL might have changed. The problem in the current code is that changes made by other clients aren't always noticed, primarily because the file status information and the callback information aren't updated in the same critical section, even if these are carried in the same reply from an RPC operation, and so the AFS_VNODE_CB_PROMISED flag is unreliable. Arranging for them to be done in the same critical section during reply decoding is tricky because of the FS.InlineBulkStatus op - which has all the statuses in the reply arriving and then all the callbacks, so they have to be buffered. It simplifies things a lot to move the critical section out of the decode phase and do it after the RPC function returns. Also new inodes (either newly fetched or newly created) aren't properly managed against a callback break happening before we get the local inode up and running. Fix this by: - There's now a combined file status and callback record (struct afs_status_cb) to carry both plus some flags. - Each operation wrapper function allocates sufficient afs_status_cb records for all the vnodes it is interested in and passes them into RPC operations to be filled in from the reply. - The FileStatus and CallBack record decoders no longer apply the new/revised status and callback information to the inode/vnode at the point of decoding and instead store the information into the record from (2). - afs_vnode_commit_status() then revises the file status, detects deletion and notes callback information inside of a single critical section. It also checks the callback break counters and cancels the callback promise if they changed during the operation. [*] Note that "callback break counters" are counters of server events that cancel one or more callback promises that the client thinks it has. The client counts the events and compares the counters before and after an operation to see if the callback promise it thinks it just got evaporated before it got recorded under lock. - Volume and server callback break counters are passed into afs_iget() allowing callback breaks concurrent with inode set up to be detected and the callback promise thence to be cancelled. - AFS validation checks are now done under RCU conditions using a read lock on cb_lock. This requires vnode->cb_interest to be made RCU safe. - If the checks in (6) fail, the callback breaker is then called under write lock on the cb_lock - but only if the callback break counter didn't change from the value read before the checks were made. - Results from FS.InlineBulkStatus that correspond to inodes we currently have in memory are now used to update those inodes' status and callback information rather than being discarded. This requires those inodes to be looked up before the RPC op is made and all their callback break values saved. To aid in this, the following changes have also been made: - Don't pass the vnode into the reply delivery functions or the decoders. The vnode shouldn't be altered anywhere in those paths. The only exception, for the moment, is for the call done hook for file lock ops that wants access to both the vnode and the call - this can be fixed at a later time. - Get rid of the call->reply[] void* array and replace it with named and typed members. This avoids confusion since different ops were mapping different reply[] members to different things. - Fix an order-1 kmalloc allocation in afs_do_lookup() and replace it with kvcalloc(). - Always get the reply time. Since callback, lock and fileserver record expiry times are calculated for several RPCs, make this mandatory. - Call afs_pages_written_back() from the operation wrapper rather than from the delivery function. - Don't store the version and type from a callback promise in a reply as the information in them is of very limited use" * tag 'afs-fixes-b-20190516' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: afs: Fix application of the results of a inline bulk status fetch afs: Pass pre-fetch server and volume break counts into afs_iget5_set() afs: Fix unlink to handle YFS.RemoveFile2 better afs: Clear AFS_VNODE_CB_PROMISED if we detect callback expiry afs: Make vnode->cb_interest RCU safe afs: Split afs_validate() so first part can be used under LOOKUP_RCU afs: Don't save callback version and type fields afs: Fix application of status and callback to be under same lock afs: Always get the reply time afs: Fix order-1 allocation in afs_do_lookup() afs: Get rid of afs_call::reply[] afs: Don't pass the vnode pointer through into the inline bulk status op

It turned out that DEBUG_SLAB_LEAK is still broken even after recent recue efforts that when there is a large number of objects like kmemleak_object which is normal on a debug kernel, # grep kmemleak /proc/slabinfo kmemleak_object 2243606 3436210 ... reading /proc/slab_allocators could easily loop forever while processing the kmemleak_object cache and any additional freeing or allocating objects will trigger a reprocessing. To make a situation worse, soft-lockups could easily happen in this sitatuion which will call printk() to allocate more kmemleak objects to guarantee an infinite loop. Also, since it seems no one had noticed when it was totally broken more than 2-year ago - see the commit fcf88917 ("slab: fix a crash by reading /proc/slab_allocators"), probably nobody cares about it anymore due to the decline of the SLAB.

Fix afs_do_lookup() such that when it does an inline bulk status fetch op, it will update inodes that are already extant (something that afs_iget() doesn't do) and to cache permits for each inode created (thereby avoiding a follow up FS.FetchStatus call to determine this). Extant inodes need looking up in advance so that their cb_break counters before and after the operation can be compared. To this end, the inode pointers are cached so that they don't need looking up again after the op.

Alex Xu reported a regression in strace, caused by the introduction of the cgroup v2 freezer. The regression can be reproduced by stracing the following simple program: #include <unistd.h> int main() { write(1, "a", 1); return 0; } An attempt to run strace ./a.out leads to the infinite loop: [ pre-main omitted ] write(1, "a", 1) = ? ERESTARTSYS (To be restarted if SA_RESTART is set) write(1, "a", 1) = ? ERESTARTSYS (To be restarted if SA_RESTART is set) write(1, "a", 1) = ? ERESTARTSYS (To be restarted if SA_RESTART is set) write(1, "a", 1) = ? ERESTARTSYS (To be restarted if SA_RESTART is set) write(1, "a", 1) = ? ERESTARTSYS (To be restarted if SA_RESTART is set) write(1, "a", 1) = ? ERESTARTSYS (To be restarted if SA_RESTART is set) [ repeats forever ] The problem occurs because the traced task leaves ptrace_stop() (and the signal handling loop) with the frozen bit set. So let's call cgroup_leave_frozen(true) unconditionally after sleeping in ptrace_stop(). With this patch applied, strace works as expected: [ pre-main omitted ] write(1, "a", 1) = 1 exit_group(0) = ? +++ exited with 0 +++ Reported-by: NAlex Xu <alex_y_xu@yahoo.ca> Fixes: 76f969e8 ("cgroup: cgroup v2 freezer") Signed-off-by: NRoman Gushchin <guro@fb.com> Acked-by: NOleg Nesterov <oleg@redhat.com> Cc: Tejun Heo <tj@kernel.org> Signed-off-by: NTejun Heo <tj@kernel.org>

Make the name of the anon inode fd "[fscontext]" instead of "fscontext". This is minor but most core-kernel anon inode fds already carry square brackets around their name: [eventfd] [eventpoll] [fanotify] [io_uring] [pidfd] [signalfd] [timerfd] [userfaultfd] For the sake of consistency lets do the same for the fscontext anon inode fd that comes with the new mount api.

When __afs_break_callback() clears the CB_PROMISED flag, it increments vnode->cb_break to trigger a future refetch of the status and callback - however it also calls afs_clear_permits(), which also increments vnode->cb_break. Fix this by removing the increment from afs_clear_permits(). Whilst we're at it, fix the conditional call to afs_put_permits() as the function checks to see if the argument is NULL, so the check is redundant.
