0d74471 Linus Torvalds 17 May 2019, 00:18:41 UTC Merge tag 'afs-fixes-b-20190516' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs 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 17 May 2019, 00:18:41 UTC

Requires some list_bl interface improvements. - Add ability for DM integrity to use a bitmap mode, that tracks regions where data and metadata are out of sync, instead of using a journal. - Improve DM thin provisioning target to not write metadata changes to disk if the thin-pool and associated thin devices are merely activated but not used. This avoids metadata corruption due to concurrent activation of thin devices across different OS instances (e.g. split brain scenarios, which ultimately would be avoided if proper device filters were used -- but not having proper filtering has proven a very common configuration mistake) - Fix missing call to path selector type->end_io in DM multipath. This fixes reported performance problems due to inaccurate path selector IO accounting causing an imbalance of IO (e.g. avoiding issuing IO to particular path due to it seemingly being heavily used). - Fix bug in DM cache metadata's loading of its discard bitset that could lead to all cache blocks being discarded if the very first cache block was discarded (thankfully in practice the first cache block is generally in use; be it FS superblock, partition table, disk label, etc). - Add testing-only DM dust target which simulates a device that has failing sectors and/or read failures. - Fix a DM init error path reference count hang that caused boot hangs if user supplied malformed input on kernel commandline. - Fix a couple issues with DM crypt target's logging being overly verbose or lacking context. - Various other small fixes to DM init, DM multipath, DM zoned, and DM crypt. * tag 'for-5.2/dm-changes-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: (42 commits) dm: fix a couple brace coding style issues dm crypt: print device name in integrity error message dm crypt: move detailed message into debug level dm ioctl: fix hang in early create error condition dm integrity: whitespace, coding style and dead code cleanup dm integrity: implement synchronous mode for reboot handling dm integrity: handle machine reboot in bitmap mode dm integrity: add a bitmap mode dm integrity: introduce a function add_new_range_and_wait() dm integrity: allow large ranges to be described dm ingerity: pass size to dm_integrity_alloc_page_list() dm integrity: introduce rw_journal_sectors() dm integrity: update documentation dm integrity: don't report unused options dm integrity: don't check null pointer before kvfree and vfree dm integrity: correctly calculate the size of metadata area dm dust: Make dm_dust_init and dm_dust_exit static dm dust: remove redundant unsigned comparison to less than zero dm mpath: always free attached_handler_name in parse_path() dm init: fix max devices/targets checks ... 16 May 2019, 22:55:48 UTC
7878c23 Qian Cai 16 May 2019, 19:57:41 UTC slab: remove /proc/slab_allocators 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 fcf88917dd43 ("slab: fix a crash by reading /proc/slab_allocators"), probably nobody cares about it anymore due to the decline of the SLAB. Just remove it entirely.

39db981 David Howells 14 May 2019, 11:33:10 UTC afs: Fix application of the results of a inline bulk status fetch 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.

a58823a David Howells 09 May 2019, 14:16:10 UTC afs: Fix application of status and callback to be under same lock When applying the status and callback in the response of an operation, apply them in the same critical section so that there's no race between checking the callback state and checking status-dependent state (such as the data version). Fix this by: (1) Allocating a joint {status,callback} record (afs_status_cb) before calling the RPC function for each vnode for which the RPC reply contains a status or a status plus a callback. A flag is set in the record to indicate if a callback was actually received. (2) These records are passed into the RPC functions to be filled in. The afs_decode_status() and yfs_decode_status() functions are removed and the cb_lock is no longer taken. (3) xdr_decode_AFSFetchStatus() and xdr_decode_YFSFetchStatus() no longer update the vnode. (4) xdr_decode_AFSCallBack() and xdr_decode_YFSCallBack() no longer update the vnode. (5) vnodes, expected data-version numbers and callback break counters (cb_break) no longer need to be passed to the reply delivery functions. Note that, for the moment, the file locking functions still need access to both the call and the vnode at the same time. (6) afs_vnode_commit_status() is now given the cb_break value and the expected data_version and the task of applying the status and the callback to the vnode are now done here. This is done under a single taking of vnode->cb_lock. (7) afs_pages_written_back() is now called by afs_store_data() rather than by the reply delivery function. afs_pages_written_back() has been moved to before the call point and is now given the first and last page numbers rather than a pointer to the call. (8) The indicator from YFS.RemoveFile2 as to whether the target file actually got removed (status.abort_code == VNOVNODE) rather than merely dropping a link is now checked in afs_unlink rather than in xdr_decode_YFSFetchStatus(). Supplementary fixes: (*) afs_cache_permit() now gets the caller_access mask from the afs_status_cb object rather than picking it out of the vnode's status record. afs_fetch_status() returns caller_access through its argument list for this purpose also. (*) afs_inode_init_from_status() now uses a write lock on cb_lock rather than a read lock and now sets the callback inside the same critical section.

8718275 David Howells 09 May 2019, 15:17:05 UTC afs: Fix order-1 allocation in afs_do_lookup() afs_do_lookup() will do an order-1 allocation to allocate status records if there are more than 39 vnodes to stat. Fix this by allocating an array of {status,callback} records for each vnode we want to examine using vmalloc() if larger than a page. This not only gets rid of the order-1 allocation, but makes it easier to grow beyond 50 records for YFS servers. It also allows us to move to {status,callback} tuples for other calls too and makes it easier to lock across the application of the status and the callback to the vnode.

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.

c7226e4 David Howells 10 May 2019, 22:03:31 UTC afs: Fix lock-wait/callback-break double locking __afs_break_callback() holds vnode->lock around its call of afs_lock_may_be_available() - which also takes that lock. Fix this by not taking the lock in __afs_break_callback(). Also, there's no point checking the granted_locks and pending_locks queues; it's sufficient to check lock_state, so move that check out of afs_lock_may_be_available() into __afs_break_callback() to replace the queue checks.

20b8391 David Howells 08 May 2019, 15:16:31 UTC afs: Make some RPC operations non-interruptible Make certain RPC operations non-interruptible, including: (*) Set attributes (*) Store data We don't want to get interrupted during a flush on close, flush on unlock, writeback or an inode update, leaving us in a state where we still need to do the writeback or update. (*) Extend lock (*) Release lock We don't want to get lock extension interrupted as the file locks on the server are time-limited. Interruption during lock release is less of an issue since the lock is time-limited, but it's better to complete the release to avoid a several-minute wait to recover it. *Setting* the lock isn't a problem if it's interrupted since we can just return to the user and tell them they were interrupted - at which point they can elect to retry. (*) Silly unlink We want to remove silly unlink files if we can, rather than leaving them for the salvager to clear up. Note that whilst these calls are no longer interruptible, they do have timeouts on them, so if the server stops responding the call will fail with something like ETIME or ECONNRESET. Without this, the following: kAFS: Unexpected error from FS.StoreData -512 appears in dmesg when a pending store data gets interrupted and some processes may just hang. Additionally, make the code that checks/updates the server record ignore failure due to interruption if the main call is uninterruptible and if the server has an address list. The next op will check it again since the expiration time on the old list has past.

This allows kafs to make things like lock-extension and writeback data storage calls non-interruptible. If this is set, signals will be ignored for operations on that call where possible - such as waiting to get a call channel on an rxrpc connection. It doesn't prevent UDP sendmsg from being interrupted, but that will be handled by packet retransmission. rxrpc_kernel_recv_data() isn't affected by this since that never waits, preferring instead to return -EAGAIN and leave the waiting to the caller. Userspace initiated calls can't be set to be uninterruptible at this time. Signed-off-by: David Howells <dhowells@redhat.com> 16 May 2019, 15:25:20 UTC
0ab4c95 David Howells 16 May 2019, 13:51:48 UTC afs: Fix error propagation from server record check/update afs_check/update_server_record() should be setting fc->error rather than fc->ac.error as they're called from within the cursor iteration function. afs_fs_cursor::error is where the error code of the attempt to call the operation on multiple servers is integrated and is the final result, whereas afs_addr_cursor::error is used to hold the error from individual iterations of the call loop. (Note there's also an afs_vl_cursor which also wraps afs_addr_cursor for accessing VL servers rather than file servers). Fix this by setting fc->error in the afs_check/update_server_record() so that any error incurred whilst talking to the VL server correctly propagates to the final result. This results in: kAFS: Unexpected error from FS.StoreData -512 being seen, even though the store-data op is non-interruptible. The error is actually coming from the server record update getting interrupted.

51eba99 David Howells 15 May 2019, 22:06:24 UTC afs: Fix "kAFS: AFS vnode with undefined type 0" Under some circumstances afs_select_fileserver() can return without setting an error in fc->error. The problem is in the no_more_servers segment where the accumulated errors from attempts to contact various servers are integrated into an afs_error-type variable 'e'. The resultant error code is, however, then abandoned. Fix this by getting the error out of e.error and putting it in 'error' so that the next part will store it into fc->error. Not doing this causes a report like the following: kAFS: AFS vnode with undefined type 0 kAFS: A=0 m=0 s=0 v=0 kAFS: vnode 20000025:1:1 because the code following the server selection loop then sees what it thinks is a successful invocation because fc.error is 0. However, it can't apply the status record because it's all zeros.

In case of failure, this reference wasn't being released, causing dm_destroy() to hang, thus hanging the whole boot process. Fix this by calling __hash_remove() in the error path.

d5c32c8 David Howells 07 May 2019, 14:06:36 UTC afs: Fix cell DNS lookup Currently, once configured, AFS cells are looked up in the DNS at regular intervals - which is a waste of resources if those cells aren't being used. It also leads to a problem where cells preloaded, but not configured, before the network is brought up end up effectively statically configured with no VL servers and are unable to get any. Fix this by not doing the DNS lookup until the first time a cell is touched. It is waited for if we don't have any cached records yet, otherwise the DNS lookup to maintain the record is done in the background. This has the downside that the first time you touch a cell, you now have to wait for the upcall to do the required DNS lookups rather than them already being cached. Further, the record is not replaced if the old record has at least one server in it and the new record doesn't have any.

"mmiowb()" is one of those operations. Although machvec is initialized very early in boot, it isn't early enough for a recent upstream kernel change that added mmiowb to the spin_unlock() path.

This should be safe because we do the real initialization of machvec before bringing up any addtional CPUs or doing any I/O.

def0fda Johannes Weiner 14 May 2019, 22:47:15 UTC mm: memcontrol: fix NUMA round-robin reclaim at intermediate level When a cgroup is reclaimed on behalf of a configured limit, reclaim needs to round-robin through all NUMA nodes that hold pages of the memcg in question. However, when assembling the mask of candidate NUMA nodes, the code only consults the *local* cgroup LRU counters, not the recursive counters for the entire subtree. Cgroup limits are frequently configured against intermediate cgroups that do not have memory on their own LRUs. In this case, the node mask will always come up empty and reclaim falls back to scanning only the current node. If a cgroup subtree has some memory on one node but the processes are bound to another node afterwards, the limit reclaim will never age or reclaim that memory anymore. To fix this, use the recursive LRU counts for a cgroup subtree to determine which nodes hold memory of that cgroup. The code has been broken like this forever, so it doesn't seem to be a problem in practice. I just noticed it while reviewing the way the LRU counters are used in general.

42a3003 Johannes Weiner 14 May 2019, 22:47:12 UTC mm: memcontrol: fix recursive statistics correctness & scalabilty Right now, when somebody needs to know the recursive memory statistics and events of a cgroup subtree, they need to walk the entire subtree and sum up the counters manually. There are two issues with this: 1. When a cgroup gets deleted, its stats are lost. The state counters should all be 0 at that point, of course, but the events are not. When this happens, the event counters, which are supposed to be monotonic, can go backwards in the parent cgroups. 2. During regular operation, we always have a certain number of lazily freed cgroups sitting around that have been deleted, have no tasks, but have a few cache pages remaining. These groups' statistics do not change until we eventually hit memory pressure, but somebody watching, say, memory.stat on an ancestor has to iterate those every time. This patch addresses both issues by introducing recursive counters at each level that are propagated from the write side when stats change. Upward propagation happens when the per-cpu caches spill over into the local atomic counter. This is the same thing we do during charge and uncharge, except that the latter uses atomic RMWs, which are more expensive; stat changes happen at around the same rate. In a sparse file test (page faults and reclaim at maximum CPU speed) with 5 cgroup nesting levels, perf shows __mod_memcg_page state at ~1%.

205b20c Johannes Weiner 14 May 2019, 22:47:06 UTC mm: memcontrol: make cgroup stats and events query API explicitly local Patch series "mm: memcontrol: memory.stat cost & correctness". The cgroup memory.stat file holds recursive statistics for the entire subtree. The current implementation does this tree walk on-demand whenever the file is read. This is giving us problems in production. 1. The cost of aggregating the statistics on-demand is high. A lot of system service cgroups are mostly idle and their stats don't change between reads, yet we always have to check them. There are also always some lazily-dying cgroups sitting around that are pinned by a handful of remaining page cache; the same applies to them. In an application that periodically monitors memory.stat in our fleet, we have seen the aggregation consume up to 5% CPU time. 2. When cgroups die and disappear from the cgroup tree, so do their accumulated vm events. The result is that the event counters at higher-level cgroups can go backwards and confuse some of our automation, let alone people looking at the graphs over time. To address both issues, this patch series changes the stat implementation to spill counts upwards when the counters change. The upward spilling is batched using the existing per-cpu cache. In a sparse file stress test with 5 level cgroup nesting, the additional cost of the flushing was negligible (a little under 1% of CPU at 100% CPU utilization, compared to the 5% of reading memory.stat during regular operation). This patch (of 4): memcg_page_state(), lruvec_page_state(), memcg_sum_events() are currently returning the state of the local memcg or lruvec, not the recursive state. In practice there is a demand for both versions, although the callers that want the recursive counts currently sum them up by hand. Per default, cgroups are considered recursive entities and generally we expect more users of the recursive counters, with the local counts being special cases. To reflect that in the name, add a _local suffix to the current implementations. The following patch will re-incarnate these functions with recursive semantics, but with an O(1) implementation.

The code later in the function assumes that param.count is at least one and if it's not then it leads to an Oops when we dereference the ZERO_SIZE_PTR. Also the addition can have an integer overflow which would lead us to allocate a smaller "pages" array than required. I can't immediately tell what the possible run times implications are, but it's safest to prevent the overflow.

871789d Chris Down 14 May 2019, 22:46:57 UTC mm, memcg: rename ambiguously named memory.stat counters and functions I spent literally an hour trying to work out why an earlier version of my memory.events aggregation code doesn't work properly, only to find out I was calling memcg->events instead of memcg->memory_events, which is fairly confusing. This naming seems in need of reworking, so make it harder to do the wrong thing by using vmevents instead of events, which makes it more clear that these are vm counters rather than memcg-specific counters. There are also a few other inconsistent names in both the percpu and aggregated structs, so these are all cleaned up to be more coherent and easy to understand. This commit contains code cleanup only: there are no logic changes.
