block, bfq: inject other-queue I/O into seeky idle queues on NCQ flash
[ Upstream commit d0edc2473be9d70f999282e1ca7863ad6ae704dc ] The Achilles' heel of BFQ is its failing to reach a high throughput with sync random I/O on flash storage with internal queueing, in case the processes doing I/O have differentiated weights. The cause of this failure is as follows. If at least two processes do sync I/O, and have a different weight from each other, then BFQ plugs I/O dispatching every time one of these processes, while it is being served, remains temporarily without pending I/O requests. This plugging is necessary to guarantee that every process enjoys a bandwidth proportional to its weight; but it empties the internal queue(s) of the drive. And this kills throughput with random I/O. So, if some processes have differentiated weights and do both sync and random I/O, the end result is a throughput collapse. This commit tries to counter this problem by injecting the service of other processes, in a controlled way, while the process in service happens to have no I/O. This injection is performed only if the medium is non rotational and performs internal queueing, and the process in service does random I/O (service injection might be beneficial for sequential I/O too, we'll work on that). As an example of the benefits of this commit, on a PLEXTOR PX-256M5S SSD, and with five processes having differentiated weights and doing sync random 4KB I/O, this commit makes the throughput with bfq grow by 400%, from 25 to 100MB/s. This higher throughput is 10MB/s lower than that reached with none. As some less random I/O is added to the mix, the throughput becomes equal to or higher than that with none. This commit is a very first attempt to recover throughput without losing control, and certainly has many limitations. One is, e.g., that the processes whose service is injected are not chosen so as to distribute the extra bandwidth they receive in accordance to their weights. Thus there might be loss of weighted fairness in some cases. Anyway, this loss concerns extra service, which would not have been received at all without this commit. Other limitations and issues will probably show up with usage.

BACKPORT: FROMLIST: block: blk-crypto for Inline Encryption
We introduce blk-crypto, which manages programming keyslots for struct bios. With blk-crypto, filesystems only need to call bio_crypt_set_ctx with the encryption key, algorithm and data_unit_num; they don't have to worry about getting a keyslot for each encryption context, as blk-crypto handles that. Blk-crypto also makes it possible for layered devices like device mapper to make use of inline encryption hardware. Blk-crypto delegates crypto operations to inline encryption hardware when available, and also contains a software fallback to the kernel crypto API. For more details, refer to Documentation/block/inline-encryption.rst.

ANDROID: block: Fix bio_crypt_should_process WARN_ON
bio_crypt_should_process would WARN that the bio did not have a keyslot in any keyslot manager even when we were on the decrypt path of blk-crypto, which is a bug. The WARN is now conditional on the caller being responible for handling encryption rather than blk-crypto (i.e. the WARN happens only if this function return true).

BACKPORT: FROMLIST: block: Add encryption context to struct bio
We must have some way of letting a storage device driver know what encryption context it should use for en/decrypting a request. However, it's the filesystem/fscrypt that knows about and manages encryption contexts. As such, when the filesystem layer submits a bio to the block layer, and this bio eventually reaches a device driver with support for inline encryption, the device driver will need to have been told the encryption context for that bio. We want to communicate the encryption context from the filesystem layer to the storage device along with the bio, when the bio is submitted to the block layer. To do this, we add a struct bio_crypt_ctx to struct bio, which can represent an encryption context (note that we can't use the bi_private field in struct bio to do this because that field does not function to pass information across layers in the storage stack). We also introduce various functions to manipulate the bio_crypt_ctx and make the bio/request merging logic aware of the bio_crypt_ctx. Bug: 137270441 Test: tested as series; see I26aac0ac7845a9064f28bb1421eb2522828a6dec Change-Id: I16d99bb97f8cd7971cc11281a0d7120c5f87d83c Signed-off-by: Satya Tangirala <satyat@google.com> Link: https://patchwork.kernel.org/patch/11214719/ |

BACKPORT: FROMLIST: block: Keyslot Manager for Inline Encryption
Inline Encryption hardware allows software to specify an encryption context (an encryption key, crypto algorithm, data unit num, data unit size, etc.) along with a data transfer request to a storage device, and the inline encryption hardware will use that context to en/decrypt the data. The inline encryption hardware is part of the storage device, and it conceptually sits on the data path between system memory and the storage device. Inline Encryption hardware implementations often function around the concept of "keyslots". These implementations often have a limited number of "keyslots", each of which can hold an encryption context (we say that an encryption context can be "programmed" into a keyslot). Requests made to the storage device may have a keyslot associated with them, and the inline encryption hardware will en/decrypt the data in the requests using the encryption context programmed into that associated keyslot. As keyslots are limited, and programming keys may be expensive in many implementations, and multiple requests may use exactly the same encryption contexts, we introduce a Keyslot Manager to efficiently manage keyslots. The keyslot manager also functions as the interface that upper layers will use to program keys into inline encryption hardware. For more information on the Keyslot Manager, refer to documentation found in block/keyslot-manager.c and linux/keyslot-manager.h.

blkcg: make blkcg_print_stat() print stats only for online blkgs
[ Upstream commit b0814361a25cba73a224548843ed92d8ea78715a ]
blkcg_print_stat() iterates blkgs under RCU and doesn't test whether
the blkg is online. This can call into pd_stat_fn() on a pd which is
still being initialized leading to an oops.
The heaviest operation - recursively summing up rwstat counters - is
already done while holding the queue_lock. Expand queue_lock to cover
the other operations and skip the blkg if it isn't online yet. The
online state is protected by both blkcg and queue locks, so this
guarantees that only online blkgs are processed.

bfq-iosched: Make BFQ default to IOPS mode on SSDs
BFQ idling causes reduced IOPS throughput on non-rotational disks. Since disk head seeking is not applicable to SSDs, it doesn't really help performance by anticipating future near-by IO requests. Idling due to anticipation of future near-by IO requests and wait on completion of submitted requests, will also effect the other bfq-queues by causing delay in their scheduling and there by effecting some time bounded applications. By turning off idling (and switching to IOPS mode), we allow other processes(bfq-queues) to dispatch IO requests down to the driver and so increase IO throughput. Following FIO benchmark results were taken on a local SSD run: RandomReads: Idling iops avg-lat(us) stddev bw ---------------------------------------------------- On 4136 1189.07 17221.65 16.9MB/s Off 7246 670.11 1054.76 29.7MB/s fio --name=temp --size=5G --time_based --ioengine=sync \ --randrepeat=0 --direct=1 --invalidate=1 --verify=0 \ --verify_fatal=0 --rw=randread --blocksize=4k \ --group_reporting=1 --directory=/data --runtime=10 \ --iodepth=64 --numjobs=5 RandomWrites: Idling iops avg-lat(us) stddev bw --------------------------------------------------- On 1368 3631.38 28234.55 5.47MB/s Off 4746 1024.61 12184.00 19.4MB/s fio --name=temp --size=5G --time_based --ioengine=sync \ --randrepeat=0 --direct=1 --invalidate=1 --verify=0 \ --verify_fatal=0 --rw=randwrite --blocksize=4k \ --group_reporting=1 --directory=/data --runtime=10 \ --iodepth=64 --numjobs=5 Change-Id: I9e55eee03917a1ab07fbd3f04635ca1a6541b860 Signed-off-by: Pradeep P V K <ppvk@codeaurora.org> |

blk-rq-qos: fix first node deletion of rq_qos_del()
commit 307f4065b9d7c1e887e8bdfb2487e4638559fea1 upstream.
rq_qos_del() incorrectly assigns the node being deleted to the head if
it was the first on the list in the !prev path. Fix it by iterating
with ** instead.

blk-wbt: fix performance regression in wbt scale_up/scale_down
commit b84477d3ebb96294f87dc3161e53fa8fe22d9bfd upstream.
scale_up wakes up waiters after scaling up. But after scaling max, it
should not wake up more waiters as waiters will not have anything to
do. This patch fixes this by making scale_up (and also scale_down)
return when threshold is reached.
This bug causes increased fdatasync latency when fdatasync and dd
conv=sync are performed in parallel on 4.19 compared to 4.14. This
bug was introduced during refactoring of blk-wbt code.
Fixes:

BACKPORT: block: annotate refault stalls from IO submission
psi tracks the time tasks wait for refaulting pages to become uptodate, but it does not track the time spent submitting the IO. The submission part can be significant if backing storage is contended or when cgroup throttling (io.latency) is in effect - a lot of time is spent in submit_bio(). In that case, we underreport memory pressure. Annotate submit_bio() to account submission time as memory stall when the bio is reading userspace workingset pages. Tested-by: Suren Baghdasaryan <surenb@google.com> Signed-off-by: Johannes Weiner <hannes@cmpxchg.org> Signed-off-by: Jens Axboe <axboe@kernel.dk> (cherry picked from commit b8e24a9300b0836a9d39f6b20746766b3b81f1bd) Conflicts: include/linux/blk_types.h (1. Manually resolved BIO_WORKINGSET being definition instead of enum.)

block: mq-deadline: Fix queue restart handling
[ Upstream commit cb8acabbe33b110157955a7425ee876fb81e6bbc ] Commit 7211aef86f79 ("block: mq-deadline: Fix write completion handling") added a call to blk_mq_sched_mark_restart_hctx() in dd_dispatch_request() to make sure that write request dispatching does not stall when all target zones are locked. This fix left a subtle race when a write completion happens during a dispatch execution on another CPU: CPU 0: Dispatch CPU1: write completion dd_dispatch_request() lock(&dd->lock); ... lock(&dd->zone_lock); dd_finish_request() rq = find request lock(&dd->zone_lock); unlock(&dd->zone_lock); zone write unlock unlock(&dd->zone_lock); ... __blk_mq_free_request check restart flag (not set) -> queue not run ... if (!rq && have writes) blk_mq_sched_mark_restart_hctx() unlock(&dd->lock) Since the dispatch context finishes after the write request completion handling, marking the queue as needing a restart is not seen from __blk_mq_free_request() and blk_mq_sched_restart() not executed leading to the dispatch stall under 100% write workloads. Fix this by moving the call to blk_mq_sched_mark_restart_hctx() from dd_dispatch_request() into dd_finish_request() under the zone lock to ensure full mutual exclusion between write request dispatch selection and zone unlock on write request completion.

block: fix null pointer dereference in blk_mq_rq_timed_out()
commit 8d6996630c03d7ceeabe2611378fea5ca1c3f1b3 upstream.
We got a null pointer deference BUG_ON in blk_mq_rq_timed_out()
as following:
[ 108.825472] BUG: kernel NULL pointer dereference, address: 0000000000000040

[ 108.843100] ret_from_fork+0x35/0x40
The bug is caused by the race between timeout handle and completion for
flush request.
When timeout handle function blk_mq_rq_timed_out() try to read
'req->q->mq_ops', the 'req' have completed and reinitiated by next
flush request, which would call blk_rq_init() to clear 'req' as 0.

blk-mq: free hw queue's resource in hctx's release handler
[ Upstream commit c7e2d94b3d1634988a95ac4d77a72dc7487ece06 ] Once blk_cleanup_queue() returns, tags shouldn't be used any more, because blk_mq_free_tag_set() may be called. Commit |

blk-iolatency: fix STS_AGAIN handling
[ Upstream commit c9b3007feca018d3f7061f5d5a14cb00766ffe9b ] The iolatency controller is based on rq_qos. It increments on rq_qos_throttle() and decrements on either rq_qos_cleanup() or rq_qos_done_bio(). a3fb01ba5af0 fixes the double accounting issue where blk_mq_make_request() may call both rq_qos_cleanup() and rq_qos_done_bio() on REQ_NO_WAIT. So checking STS_AGAIN prevents the double decrement. The above works upstream as the only way we can get STS_AGAIN is from blk_mq_get_request() failing. The STS_AGAIN handling isn't a real problem as bio_endio() skipping only happens on reserved tag allocation failures which can only be caused by driver bugs and already triggers WARN. However, the fix creates a not so great dependency on how STS_AGAIN can be propagated. Internally, we (Facebook) carry a patch that kills read ahead if a cgroup is io congested or a fatal signal is pending. This combined with chained bios progagate their bi_status to the parent is not already set can can cause the parent bio to not clean up properly even though it was successful. This consequently leaks the inflight counter and can hang all IOs under that blkg. To nip the adverse interaction early, this removes the rq_qos_cleanup() callback in iolatency in favor of cleaning up always on the rq_qos_done_bio() path.

block: use current active bfqq to update statistics
Use the current active bfq-queue to update bfq-group statitics. It could be possible that the current active serving bfq-queue can expire if the allocated time/budget for the queue got expired. During this time, it will select a new queue that to be served for its service tree. If there were no more queues to be served, then it will choose a next group of queues to be served from its group service tree. So, the selection of the new request from its new group and queue are updated via __bfq_dispatch_request() fn. As "in_serv_queue" variable is not updated again the group associated with "in_serv_queue" queue can be freed, if there were no more active queues. So, with picking in_serv_queue as active queue, and updating its group statistics one will see a kernel panic as below. [ 120.572960] Hardware name: Qualcomm Technologies, Inc.

block, bfq: handle NULL return value by bfq_init_rq()
[ Upstream commit fd03177c33b287c6541f4048f1d67b7b45a1abc9 ] As reported in [1], the call bfq_init_rq(rq) may return NULL in case of OOM (in particular, if rq->elv.icq is NULL because memory allocation failed in failed in ioc_create_icq()). This commit handles this circumstance.

block, scsi: Change the preempt-only flag into a counter
commit cd84a62e0078dce09f4ed349bec84f86c9d54b30 upstream. The RQF_PREEMPT flag is used for three purposes: - In the SCSI core, for making sure that power management requests are executed even if a device is in the "quiesced" state. - For domain validation by SCSI drivers that use the parallel port. - In the IDE driver, for IDE preempt requests. Rename "preempt-only" into "pm-only" because the primary purpose of this mode is power management. Since the power management core may but does not have to resume a runtime suspended device before performing system-wide suspend and since a later patch will set "pm-only" mode as long as a block device is runtime suspended, make it possible to set "pm-only" mode from more than one context. Since with this change scsi_device_quiesce() is no longer idempotent, make that function return early if it is called for a quiesced queue.

block/bio-integrity: fix a memory leak bug
[ Upstream commit e7bf90e5afe3aa1d1282c1635a49e17a32c4ecec ] In bio_integrity_prep(), a kernel buffer is allocated through kmalloc() to hold integrity metadata. Later on, the buffer will be attached to the bio structure through bio_integrity_add_page(), which returns the number of bytes of integrity metadata attached. Due to unexpected situations, bio_integrity_add_page() may return 0. As a result, bio_integrity_prep() needs to be terminated with 'false' returned to indicate this error. However, the allocated kernel buffer is not freed on this execution path, leading to a memory leak. To fix this issue, free the allocated buffer before returning from bio_integrity_prep().

block: init flush rq ref count to 1
[ Upstream commit b554db147feea39617b533ab6bca247c91c6198a ] We discovered a problem in newer kernels where a disconnect of a NBD device while the flush request was pending would result in a hang. This is because the blk mq timeout handler does if (!refcount_inc_not_zero(&rq->ref)) return true; to determine if it's ok to run the timeout handler for the request. Flush_rq's don't have a ref count set, so we'd skip running the timeout handler for this request and it would just sit there in limbo forever. Fix this by always setting the refcount of any request going through blk_init_rq() to 1. I tested this with a nbd-server that dropped flush requests to verify that it hung, and then tested with this patch to verify I got the timeout as expected and the error handling kicked in.

blkcg: update blkcg_print_stat() to handle larger outputs
commit f539da82f2158916e154d206054e0efd5df7ab61 upstream.
Depending on the number of devices, blkcg stats can go over the
default seqfile buf size. seqfile normally retries with a larger
buffer but since the ->pd_stat() addition, blkcg_print_stat() doesn't
tell seqfile that overflow has happened and the output gets printed
truncated. Fix it by calling seq_commit() w/ -1 on possible
overflows.

blk-iolatency: clear use_delay when io.latency is set to zero
commit 5de0073fcd50cc1f150895a7bb04d3cf8067b1d7 upstream.
If use_delay was non-zero when the latency target of a cgroup was set
to zero, it will stay stuck until io.latency is enabled on the cgroup
again. This keeps readahead disabled for the cgroup impacting
performance negatively.

blk-iolatency: only account submitted bios
[ Upstream commit a3fb01ba5af066521f3f3421839e501bb2c71805 ] As is, iolatency recognizes done_bio and cleanup as ending paths. If a request is marked REQ_NOWAIT and fails to get a request, the bio is cleaned up via rq_qos_cleanup() and ended in bio_wouldblock_error(). This results in underflowing the inflight counter. Fix this by only accounting bios that were actually submitted.

block, bfq: NULL out the bic when it's no longer valid
commit dbc3117d4ca9e17819ac73501e914b8422686750 upstream. In reboot tests on several devices we were seeing a "use after free" when slub_debug or KASAN was enabled. The kernel complained about: Unable to handle kernel paging request at virtual address 6b6b6c2b ...which is a classic sign of use after free under slub_debug. The stack crawl in kgdb looked like: 0 test_bit (addr=<optimized out>, nr=<optimized out>) 1 bfq_bfqq_busy (bfqq=<optimized out>) 2 bfq_select_queue (bfqd=<optimized out>) 3 __bfq_dispatch_request (hctx=<optimized out>) 4 bfq_dispatch_request (hctx=<optimized out>) 5 0xc056ef00 in blk_mq_do_dispatch_sched (hctx=0xed249440) 6 0xc056f728 in blk_mq_sched_dispatch_requests (hctx=0xed249440) 7 0xc0568d24 in __blk_mq_run_hw_queue (hctx=0xed249440) 8 0xc0568d94 in blk_mq_run_work_fn (work=<optimized out>) 9 0xc024c5c4 in process_one_work (worker=0xec6d4640, work=0xed249480) 10 0xc024cff4 in worker_thread (__worker=0xec6d4640) Digging in kgdb, it could be found that, though bfqq looked fine, bfqq->bic had been freed. Through further digging, I postulated that perhaps it is illegal to access a "bic" (AKA an "icq") after bfq_exit_icq() had been called because the "bic" can be freed at some point in time after this call is made. I confirmed that there certainly were cases where the exact crashing code path would access the "bic" after bfq_exit_icq() had been called. Sspecifically I set the "bfqq->bic" to (void *)0x7 and saw that the bic was 0x7 at the time of the crash. To understand a bit more about why this crash was fairly uncommon (I saw it only once in a few hundred reboots), you can see that much of the time bfq_exit_icq_fbqq() fully frees the bfqq and thus it can't access the ->bic anymore. The only case it doesn't is if bfq_put_queue() sees a reference still held. However, even in the case when bfqq isn't freed, the crash is still rare. Why? I tracked what happened to the "bic" after the exit routine. It doesn't get freed right away. Rather, put_io_context_active() eventually called put_io_context() which queued up freeing on a workqueue. The freeing then actually happened later than that through call_rcu(). Despite all these delays, some extra debugging showed that all the hoops could be jumped through in time and the memory could be freed causing the original crash. Phew! To make a long story short, assuming it truly is illegal to access an icq after the "exit_icq" callback is finished, this patch is needed.

block, bfq: increase idling for weight-raised queues
[ Upstream commit 778c02a236a8728bb992de10ed1f12c0be5b7b0e ] If a sync bfq_queue has a higher weight than some other queue, and remains temporarily empty while in service, then, to preserve the bandwidth share of the queue, it is necessary to plug I/O dispatching until a new request arrives for the queue. In addition, a timeout needs to be set, to avoid waiting for ever if the process associated with the queue has actually finished its I/O. Even with the above timeout, the device is however not fed with new I/O for a while, if the process has finished its I/O. If this happens often, then throughput drops and latencies grow. For this reason, the timeout is kept rather low: 8 ms is the current default. Unfortunately, such a low value may cause, on the opposite end, a violation of bandwidth guarantees for a process that happens to issue new I/O too late. The higher the system load, the higher the probability that this happens to some process. This is a problem in scenarios where service guarantees matter more than throughput. One important case are weight-raised queues, which need to be granted a very high fraction of the bandwidth. To address this issue, this commit lower-bounds the plugging timeout for weight-raised queues to 20 ms. This simple change provides relevant benefits. For example, on a PLEXTOR PX-256M5S, with which gnome-terminal starts in 0.6 seconds if there is no other I/O in progress, the same applications starts in - 0.8 seconds, instead of 1.2 seconds, if ten files are being read sequentially in parallel - 1 second, instead of 2 seconds, if, in parallel, five files are being read sequentially, and five more files are being written sequentially Tested-by: Holger Hoffstätte <holger@applied-asynchrony.com> Tested-by: Oleksandr Natalenko <oleksandr@natalenko.name> Signed-off-by: Paolo Valente <paolo.valente@linaro.org> Signed-off-by: Jens Axboe <axboe@kernel.dk> Signed-off-by: Sasha Levin <sashal@kernel.org> |

blk-mq: move cancel of requeue_work into blk_mq_release
[ Upstream commit fbc2a15e3433058582e5635aabe48a3011a644a8 ] With holding queue's kobject refcount, it is safe for driver to schedule requeue. However, blk_mq_kick_requeue_list() may be called after blk_sync_queue() is done because of concurrent requeue activities, then requeue work may not be completed when freeing queue, and kernel oops is triggered. So moving the cancel of requeue_work into blk_mq_release() for avoiding race between requeue and freeing queue.

block: sed-opal: fix IOC_OPAL_ENABLE_DISABLE_MBR
[ Upstream commit 78bf47353b0041865564deeed257a54f047c2fdc ] The implementation of IOC_OPAL_ENABLE_DISABLE_MBR handled the value opal_mbr_data.enable_disable incorrectly: enable_disable is expected to be one of OPAL_MBR_ENABLE(0) or OPAL_MBR_DISABLE(1). enable_disable was passed directly to set_mbr_done and set_mbr_enable_disable where is was interpreted as either OPAL_TRUE(1) or OPAL_FALSE(0). The end result was that calling IOC_OPAL_ENABLE_DISABLE_MBR with OPAL_MBR_ENABLE actually disabled the shadow MBR and vice versa. This patch adds correct conversion from OPAL_MBR_DISABLE/ENABLE to OPAL_FALSE/TRUE. The change affects existing programs using IOC_OPAL_ENABLE_DISABLE_MBR but this is typically used only once when setting up an Opal drive.

bfq: update internal depth state when queue depth changes
commit 77f1e0a52d26242b6c2dba019f6ebebfb9ff701e upstream
A previous commit moved the shallow depth and BFQ depth map calculations
to be done at init time, moving it outside of the hotter IO path. This
potentially causes hangs if the users changes the depth of the scheduler
map, by writing to the 'nr_requests' sysfs file for that device.
Add a blk-mq-sched hook that allows blk-mq to inform the scheduler if
the depth changes, so that the scheduler can update its internal state.

ANDROID: block/cfq-iosched: make group_idle per io cgroup tunable
If group_idle is made per io cgroup tunable, it gives more flexibility in tuning the performance of each group. If no value is set, it will just use the original default value. Bug: 117857342 Bug: 132282125 Test: values could be set to each group correctly Signed-off-by: Rick Yiu <rickyiu@google.com> Change-Id: I9aba172419f1819f459e8305b909630fa8305978 |

block: pass no-op callback to INIT_WORK().
[ Upstream commit 2e3c18d0ada16f145087b2687afcad1748c0827c ] syzbot is hitting flush_work() warning caused by commit 4d43d395fed12463 ("workqueue: Try to catch flush_work() without INIT_WORK().") [1]. Although that commit did not expect INIT_WORK(NULL) case, calling flush_work() without setting a valid callback should be avoided anyway. Fix this problem by setting a no-op callback instead of NULL.

commit a3761c3c91209b58b6f33bf69dd8bb8ec0c9d925 upstream. When bio_add_pc_page() fails in bio_copy_user_iov() we should free the page we just allocated otherwise we are leaking it.

block, bfq: fix in-service-queue check for queue merging
[ Upstream commit 058fdecc6de7cdecbf4c59b851e80eb2d6c5295f ] When a new I/O request arrives for a bfq_queue, say Q, bfq checks whether that request is close to (a) the head request of some other queue waiting to be served, or (b) the last request dispatched for the in-service queue (in case Q itself is not the in-service queue) If a queue, say Q2, is found for which the above condition holds, then bfq merges Q and Q2, to hopefully get a more sequential I/O in the resulting merged queue, and thus a possibly higher throughput. Case (b) is checked by comparing the new request for Q with the last request dispatched, assuming that the latter necessarily belonged to the in-service queue. Unfortunately, this assumption is no longer always correct, since commit d0edc2473be9 ("block, bfq: inject other-queue I/O into seeky idle queues on NCQ flash"). When the assumption does not hold, queues that must not be merged may be merged, causing unexpected loss of control on per-queue service guarantees. This commit solves this problem by adding an extra field, which stores the actual last request dispatched for the in-service queue, and by using this new field to correctly check case (b).

dm-default-key, f2fs, ICE: support dm-default-key with f2fs/ICE
This patch fixes assigning bi_crypt_key for moving data which was previously encrypted by f2fs. Note that, dm-default-key should not assign bi_crypt_key, if bi_crypt_skip is set. The sceanrios is: 1. write data with user key by f2fs - ENC(KU, IVU, DATA) 2. log out user key 3. read data #1 w/o user key from LBA #a 4. dm-default-key assigns default key - DEC(KD, LBA#a, ENC(KU, IVU, DATA)) 5. write data #1 w/o user key into LBA #b 6. dm-default-key assigns default key - ENC(KD, LBA#b, DEC(KD, LBA#a, ENC(KU, IVU, DATA))) 7. Read DATA out with valid logged-in user key - DEC(KU, IVU, ENC(KD, LBA#b, DEC(KD, LBA#a, ENC(KU, IVU, DATA)))) So, this patch introduces bi_crypt_skip to avoid 4. ~ 6 with right flow: 1. write data with user key by f2fs - ENC(KU, IVU, DATA) 2. log out user key 3. read data #1 w/o user key from LBA #a 4. dm-default-key skip to assign default key - ENC(KU, IVU, DATA) 5. write data #1 w/o user key into LBA #b 6. dm-default-key skips to assign default key - ENC(KU, IVU, DATA) 7. Try to read DATA with valid logged-in user key - DEC(KU, IVU, ENC(KU, IVU, DATA)) Change-Id: I4a047ff0d019cd062bdf99e8e0b7cea243721fb7 Signed-off-by: Jaegeuk Kim <jaegeuk@google.com> Signed-off-by: Shivaprasad Hongal <shongal@codeaurora.org> Signed-off-by: Barani Muthukumaran <bmuthuku@codeaurora.org> |

ANDROID: dm table: propagate inline encryption flag to dm devices
If all targets in a device-mapper table support inline encryption, mark the mapped device as supporting inline encryption. This will allow filesystems such as ext4 to tell whether the hardware supports inline encryption even in the case where there is an intervening dm device.

blk-mq: insert rq with DONTPREP to hctx dispatch list when requeue
[ Upstream commit aef1897cd36dcf5e296f1d2bae7e0d268561b685 ] When requeue, if RQF_DONTPREP, rq has contained some driver specific data, so insert it to hctx dispatch list to avoid any merge. Take scsi as example, here is the trace event log (no io scheduler, because RQF_STARTED would prevent merging), kworker/0:1H-339 [000] ...1 2037.209289: block_rq_insert: 8,0 R 4096 () 32768 + 8 [kworker/0:1H] scsi_inert_test-1987 [000] .... 2037.220465: block_bio_queue: 8,0 R 32776 + 8 [scsi_inert_test] scsi_inert_test-1987 [000] ...2 2037.220466: block_bio_backmerge: 8,0 R 32776 + 8 [scsi_inert_test] kworker/0:1H-339 [000] .... 2047.220913: block_rq_issue: 8,0 R 8192 () 32768 + 16 [kworker/0:1H] scsi_inert_test-1996 [000] ..s1 2047.221007: block_rq_complete: 8,0 R () 32768 + 8 [0] scsi_inert_test-1996 [000] .Ns1 2047.221045: block_rq_requeue: 8,0 R () 32776 + 8 [0] kworker/0:1H-339 [000] ...1 2047.221054: block_rq_insert: 8,0 R 4096 () 32776 + 8 [kworker/0:1H] kworker/0:1H-339 [000] ...1 2047.221056: block_rq_issue: 8,0 R 4096 () 32776 + 8 [kworker/0:1H] scsi_inert_test-1986 [000] ..s1 2047.221119: block_rq_complete: 8,0 R () 32776 + 8 [0] (32768 + 8) was requeued by scsi_queue_insert and had RQF_DONTPREP. Then it was merged with (32776 + 8) and issued. Due to RQF_DONTPREP, the sdb only contained the part of (32768 + 8), then only that part was completed. The lucky thing was that scsi_io_completion detected it and requeued the remaining part. So we didn't get corrupted data. However, the requeue of (32776 + 8) is not expected.

Note that quiesce_queue is not needed as this only updating iolatency configuration about which dispatching request_queue doesn't care.

blk-mq: fix a hung issue when fsync
[ Upstream commit 85bd6e61f34dffa8ec2dc75ff3c02ee7b2f1cbce ]
Florian reported a io hung issue when fsync(). It should be
triggered by following race condition.
data + post flush a flush
blk_flush_complete_seq
case REQ_FSEQ_DATA
blk_flush_queue_rq
issued to driver blk_mq_dispatch_rq_list
try to issue a flush req
failed due to NON-NCQ command
.queue_rq return BLK_STS_DEV_RESOURCE
request completion
req->end_io // doesn't check RESTART
mq_flush_data_end_io
case REQ_FSEQ_POSTFLUSH
blk_kick_flush
do nothing because previous flush
has not been completed
blk_mq_run_hw_queue
insert rq to hctx->dispatch
due to RESTART is still set, do nothing
To fix this, replace the blk_mq_run_hw_queue in mq_flush_data_end_io
with blk_mq_sched_restart to check and clear the RESTART flag.

block: mq-deadline: Fix write completion handling
commit 7211aef86f79583e59b88a0aba0bc830566f7e8e upstream.
For a zoned block device using mq-deadline, if a write request for a
zone is received while another write was already dispatched for the same
zone, dd_dispatch_request() will return NULL and the newly inserted
write request is kept in the scheduler queue waiting for the ongoing
zone write to complete. With this behavior, when no other request has
been dispatched, rq_list in blk_mq_sched_dispatch_requests() is empty
and blk_mq_sched_mark_restart_hctx() not called. This in turn leads to
__blk_mq_free_request() call of blk_mq_sched_restart() to not run the
queue when the already dispatched write request completes. The newly
dispatched request stays stuck in the scheduler queue until eventually
another request is submitted.
This problem does not affect SCSI disk as the SCSI stack handles queue
restart on request completion. However, this problem is can be triggered
the nullblk driver with zoned mode enabled.
Fix this by always requesting a queue restart in dd_dispatch_request()
if no request was dispatched while WRITE requests are queued.

block: deactivate blk_stat timer in wbt_disable_default()
commit 544fbd16a461a318cd80537d1331c0df5c6cf930 upstream. rwb_enabled() can't be changed when there is any inflight IO. wbt_disable_default() may set rwb->wb_normal as zero, however the blk_stat timer may still be pending, and the timer function will update wrb->wb_normal again.

blk-mq: punt failed direct issue to dispatch list
commit c616cbee97aed4bc6178f148a7240206dcdb85a6 upstream. After the direct dispatch corruption fix, we permanently disallow direct dispatch of non read/write requests. This works fine off the normal IO path, as they will be retried like any other failed direct dispatch request. But for the blk_insert_cloned_request() that only DM uses to bypass the bottom level scheduler, we always first attempt direct dispatch. For some types of requests, that's now a permanent failure, and no amount of retrying will make that succeed. This results in a livelock. Instead of making special cases for what we can direct issue, and now having to deal with DM solving the livelock while still retaining a BUSY condition feedback loop, always just add a request that has been through ->queue_rq() to the hardware queue dispatch list. These are safe to use as no merging can take place there. Additionally, if requests do have prepped data from drivers, we aren't dependent on them not sharing space in the request structure to safely add them to the IO scheduler lists. This basically reverts ffe81d45322c and is based on a patch from Ming, but with the list insert case covered as well.

blk-mq: fix corruption with direct issue
commit ffe81d45322cc3cb140f0db080a4727ea284661e upstream.
If we attempt a direct issue to a SCSI device, and it returns BUSY, then
we queue the request up normally. However, the SCSI layer may have
already setup SG tables etc for this particular command. If we later
merge with this request, then the old tables are no longer valid. Once
we issue the IO, we only read/write the original part of the request,
not the new state of it.
This causes data corruption, and is most often noticed with the file
system complaining about the just read data being invalid:
[ 235.934465] EXT4-fs error (device sda1): ext4_iget:4831: inode #7142: comm dpkg-query: bad extra_isize 24937 (inode size 256)
because most of it is garbage...
This doesn't happen from the normal issue path, as we will simply defer
the request to the hardware queue dispatch list if we fail. Once it's on
the dispatch list, we never merge with it.
Fix this from the direct issue path by flagging the request as
REQ_NOMERGE so we don't change the size of it before issue.

block, bfq: correctly charge and reset entity service in all cases
[ Upstream commit cbeb869a3d1110450186b738199963c5e68c2a71 ] BFQ schedules entities (which represent either per-process queues or groups of queues) as a function of their timestamps. In particular, as a function of their (virtual) finish times. The finish time of an entity is computed as a function of the budget assigned to the entity, assuming, tentatively, that the entity, once in service, will receive an amount of service equal to its budget. Then, when the entity is expired because it finishes to be served, this finish time is updated as a function of the actual service received by the entity. This allows the entity to be correctly charged with only the service received, and then to be correctly re-scheduled. Yet an entity may receive service also while not being the entity in service (in the scheduling environment of its parent entity), for several reasons. If the entity remains with no backlog while receiving this 'unofficial' service, then it is expired. Also on such an expiration, the finish time of the entity should be updated to account for only the service actually received by the entity. Unfortunately, such an update is not performed for an entity expiring without being the entity in service. In a similar vein, the service counter of the entity in service is reset when the entity is expired, to be ready to be used for next service cycle. This reset too should be performed also in case an entity is expired because it remains empty after receiving service while not being the entity in service. But in this case the reset is not performed. This commit performs the above update of the finish time and reset of the service received, also for an entity expiring while not being the entity in service.

block: fix deadline elevator drain for zoned block devices
When the deadline scheduler is used with a zoned block device, writes
to a zone will be dispatched one at a time. This causes the warning
message:
deadline: forced dispatching is broken (nr_sorted=X), please report this
to be displayed when switching to another elevator with the legacy I/O
path while write requests to a zone are being retained in the scheduler
queue.
Prevent this message from being displayed when executing

loop until all writes are dispatched and completed, resulting in the
desired elevator queue drain without extensive modifications to the
deadline code itself to handle forced-dispatch calls.

block: use nanosecond resolution for iostat
Klaus Kusche reported that the I/O busy time in /proc/diskstats was not
updating properly on 4.18. This is because we started using ktime to
track elapsed time, and we convert nanoseconds to jiffies when we update
the partition counter. However, this gets rounded down, so any I/Os that
take less than a jiffy are not accounted for. Previously in this case,
the value of jiffies would sometimes increment while we were doing I/O,
so at least some I/Os were accounted for.
Let's convert the stats to use nanoseconds internally. We still report
milliseconds as before, now more accurately than ever. The value is
still truncated to 32 bits for backwards compatibility.

blkcg: use tryget logic when associating a blkg with a bio
There is a very small change a bio gets caught up in a really
unfortunate race between a task migration, cgroup exiting, and itself
trying to associate with a blkg. This is due to css offlining being
performed after the css->refcnt is killed which triggers removal of
blkgs that reach their blkg->refcnt of 0.
To avoid this, association with a blkg should use tryget and fallback to
using the root_blkg.

blkcg: delay blkg destruction until after writeback has finished
Currently, blkcg destruction relies on a sequence of events:
1. Destruction starts. blkcg_css_offline() is called and blkgs
release their reference to the blkcg. This immediately destroys
the cgwbs (writeback).
2. With blkgs giving up their reference, the blkcg ref count should
become zero and eventually call blkcg_css_free() which finally
frees the blkcg.
Jiufei Xue reported that there is a race between blkcg_bio_issue_check()
and cgroup_rmdir(). To remedy this, blkg destruction becomes contingent
on the completion of all writeback associated with the blkcg. A count of
the number of cgwbs is maintained and once that goes to zero, blkg
destruction can follow. This should prevent premature blkg destruction
related to writeback.
The new process for blkcg cleanup is as follows:
1. Destruction starts. blkcg_css_offline() is called which offlines
writeback. Blkg destruction is delayed on the cgwb_refcnt count to
avoid punting potentially large amounts of outstanding writeback
to root while maintaining any ongoing policies. Here, the base
cgwb_refcnt is put back.
2. When the cgwb_refcnt becomes zero, blkcg_destroy_blkgs() is called
and handles destruction of blkgs. This is where the css reference
held by each blkg is released.
3. Once the blkcg ref count goes to zero, blkcg_css_free() is called.
This finally frees the blkg.
It seems in the past blk-throttle didn't do the most understandable
things with taking data from a blkg while associating with current. So,
the simplification and unification of what blk-throttle is doing caused
this.

A previous commit removed the ability to have per-rq flags. We used

Add a queue quiesce around changing the wbt latency settings from sysfs
to work around this. With that, we can reliably put the enabled check in
our bio_to_wbt_flags(), since we know the WBT_TRACKED flag will be
consistent for the lifetime of the request.

So we could use q_usage_counter to avoid the race. percpu_ref_is_zero is used here so that we will not miss any in-flight request. The access to nr_hw_queues and queue_hw_ctx in blk_mq_queue_tag_busy_iter are under rcu critical section, __blk_mq_update_nr_hw_queues could use synchronize_rcu to ensure the zeroed q_usage_counter to be globally visible.

blk-mq: init hctx sched after update ctx and hctx mapping
Currently, when update nr_hw_queues, IO scheduler's init_hctx will be invoked before the mapping between ctx and hctx is adapted correctly by blk_mq_map_swqueue. The IO scheduler init_hctx (kyber) may depend on this mapping and get wrong result and panic finally. A simply way to fix this is that switch the IO scheduler to 'none' before update the nr_hw_queues, and then switch it back after update nr_hw_queues. blk_mq_sched_init_/exit_hctx are removed due to nobody use them any more.

block, bfq: return nbytes and not zero from struct cftype .write() method
The value that struct cftype .write() method returns is then directly
returned to userspace as the value returned by write() syscall, so it
should be the number of bytes actually written (or consumed) and not zero.
Returning zero from write() syscall makes programs like /bin/echo or bash

block, bfq: reduce write overcharge
When a sync request is dispatched, the queue that contains that request, and all the ancestor entities of that queue, are charged with the number of sectors of the request. In constrast, if the request is async, then the queue and its ancestor entities are charged with the number of sectors of the request, multiplied by an overcharge factor. This throttles the bandwidth for async I/O, w.r.t. to sync I/O, and it is done to counter the tendency of async writes to steal I/O throughput to reads. On the opposite end, the lower this parameter, the stabler I/O control, in the following respect. The lower this parameter is, the less the bandwidth enjoyed by a group decreases - when the group does writes, w.r.t. to when it does reads; - when other groups do reads, w.r.t. to when they do writes. The fixes "block, bfq: always update the budget of an entity when needed" and "block, bfq: readd missing reset of parent-entity service" improved I/O control in bfq to such an extent that it has been possible to revise this overcharge factor downwards. This commit introduces the resulting, new value. Signed-off-by: Paolo Valente <paolo.valente@linaro.org> Signed-off-by: Jens Axboe <axboe@kernel.dk> |

block, bfq: readd missing reset of parent-entity service
The received-service counter needs to be equal to 0 when an entity is
set in service. Unfortunately, commit "block, bfq: fix service being
wrongly set to zero in case of preemption" mistakenly removed the
resetting of this counter for the parent entities of the bfq_queue
being set in service. This commit fixes this issue by resetting
service for parent entities, directly on the expiration of the
in-service bfq_queue.

Blk-throttle: reduce tail io latency when iops limit is enforced
When an application's iops has exceeded its cgroup's iops limit, surely it is throttled and kernel will set a timer for dispatching, thus IO latency includes the delay. However, the dispatch delay which is calculated by the limit and the elapsed jiffies is suboptimal. As the dispatch delay is only calculated once the application's iops is (iops limit + 1), it doesn't need to wait any longer than the remaining time of the current slice. The difference can be proved by the following fio job and cgroup iops setting, ----- $ echo 4 > /mnt/config/nullb/disk1/mbps # limit nullb's bandwidth to 4MB/s for testing. $ echo "253:1 riops=100 rbps=max" > /sys/fs/cgroup/unified/cg1/io.max $ cat r2.job [global] name=fio-rand-read filename=/dev/nullb1 rw=randread bs=4k direct=1 numjobs=1 time_based=1 runtime=60 group_reporting=1 [file1] size=4G ioengine=libaio iodepth=1 rate_iops=50000 norandommap=1 thinktime=4ms ----- wo patch: file1: (g=0): rw=randread, bs=(R) 4096B-4096B, (W) 4096B-4096B, (T) 4096B-4096B, ioengine=libaio, iodepth=1 fio-3.7-66-gedfc Starting 1 process read: IOPS=99, BW=400KiB/s (410kB/s)(23.4MiB/60001msec) slat (usec): min=10, max=336, avg=27.71, stdev=17.82 clat (usec): min=2, max=28887, avg=5929.81, stdev=7374.29 lat (usec): min=24, max=28901, avg=5958.73, stdev=7366.22 clat percentiles (usec): | 1.00th=[ 4], 5.00th=[ 4], 10.00th=[ 4], 20.00th=[ 4], | 30.00th=[ 4], 40.00th=[ 4], 50.00th=[ 6], 60.00th=[11731], | 70.00th=[11863], 80.00th=[11994], 90.00th=[12911], 95.00th=[22676], | 99.00th=[23725], 99.50th=[23987], 99.90th=[23987], 99.95th=[25035], | 99.99th=[28967] w/ patch: file1: (g=0): rw=randread, bs=(R) 4096B-4096B, (W) 4096B-4096B, (T) 4096B-4096B, ioengine=libaio, iodepth=1 fio-3.7-66-gedfc Starting 1 process read: IOPS=100, BW=400KiB/s (410kB/s)(23.4MiB/60005msec) slat (usec): min=10, max=155, avg=23.24, stdev=16.79 clat (usec): min=2, max=12393, avg=5961.58, stdev=5959.25 lat (usec): min=23, max=12412, avg=5985.91, stdev=5951.92 clat percentiles (usec): | 1.00th=[ 3], 5.00th=[ 3], 10.00th=[ 4], 20.00th=[ 4], | 30.00th=[ 4], 40.00th=[ 5], 50.00th=[ 47], 60.00th=[11863], | 70.00th=[11994], 80.00th=[11994], 90.00th=[11994], 95.00th=[11994], | 99.00th=[11994], 99.50th=[11994], 99.90th=[12125], 99.95th=[12125], | 99.99th=[12387] Signed-off-by: Liu Bo <bo.liu@linux.alibaba.com> Signed-off-by: Jens Axboe <axboe@kernel.dk> |

blk-mq: count the hctx as active before allocating tag
Currently, we count the hctx as active after allocate driver tag successfully. If a previously inactive hctx try to get tag first time, it may fails and need to wait. However, due to the stale tag ->active_queues, the other shared-tags users are still able to occupy all driver tags while there is someone waiting for tag. Consequently, even if the previously inactive hctx is waked up, it still may not be able to get a tag and could be starved. To fix it, we count the hctx as active before try to allocate driver tag, then when it is waiting the tag, the other shared-tag users will reserve budget for it.

The original intention of the code seems to be to wake up one thread only however, it uses wake_up_all() in __wbt_done(), and then uses the following check in __wbt_wait to have only one thread actually get out of the wait loop: if (waitqueue_active(&rqw->wait) && rqw->wait.head.next != &wait->entry) return false; The problem with this is that the wait entry in wbt_wait is define with DEFINE_WAIT, which uses the autoremove wakeup function. That means that the above check is invalid - the wait entry will have been removed from the queue already by the time we hit the check in the loop. Secondly, auto-removing the wait entries also means that the wait queue essentially gets reordered "randomly" (e.g. threads re-add themselves in the order they got to run after being woken up). Additionally, new requests entering wbt_wait might overtake requests that were queued earlier, because the wait queue will be (temporarily) empty after the wake_up_all, so the waitqueue_active check will not stop them. This can cause certain threads to starve under high load. The fix is to leave the woken up requests in the queue and remove them in finish_wait() once the current thread breaks out of the wait loop in __wbt_wait. This will ensure new requests always end up at the back of the queue, and they won't overtake requests that are already in the wait queue. With that change, the loop in wbt_wait is also in line with many other wait loops in the kernel. Waking up just one thread drastically reduces lock contention, as does moving the wait queue add/remove out of the loop. A significant drop in lockdep's lock contention numbers is seen when running the test application on the patched kernel.

blk-mq: fix updating tags depth
The passed 'nr' from userspace represents the total depth, meantime inside 'struct blk_mq_tags', 'nr_tags' stores the total tag depth, and 'nr_reserved_tags' stores the reserved part. There are two issues in blk_mq_tag_update_depth() now: 1) for growing tags, we should have used the passed 'nr', and keep the number of reserved tags not changed. 2) the passed 'nr' should have been used for checking against 'tags->nr_tags', instead of number of the normal part. This patch fixes the above two cases, and avoids kernel crash caused by wrong resizing sbitmap queue. Cc: "Ewan D.

block: make iolatency avg_lat exponentially decay
Currently, avg_lat is calculated by accumulating the mean of every window in a long running cumulative average. As time goes on, the metric becomes less and less useful due to the accumulated history. This patch reuses the same calculation done in load averages to make the avg_lat metric more lively. Unlike load averages, the avg only advances when a window elapses (due to an io). Idle periods extend the most recent window. Bucketing is used to limit the history of avg_lat by binding it to the window size. So, the window range for 1/exp (decay rate) is [1 min, 2.5 min) when windows elapse immediately. The current sample window size is exposed in the debug info to enable calculation of the window range.

block: blk_init_allocated_queue() set q->fq as NULL in the fail case
We find the memory use-after-free issue in __blk_drain_queue()
on the kernel 4.14. After read the latest kernel 4.18-rc6 we
think it has the same problem.
Memory is allocated for q->fq in the blk_init_allocated_queue().
If the elevator init function called with error return, it will
run into the fail case to free the q->fq.
Then the __blk_drain_queue() uses the same memory after the free
of the q->fq, it will lead to the unpredictable event.
The patch is to set q->fq as NULL in the fail case of
blk_init_allocated_queue().

partitions/aix: fix usage of uninitialized lv_info and lvname structures
The if-block that sets a successful return value in aix_partition()
uses 'lvip[].pps_per_lv' and 'n[].name' potentially uninitialized.
For example, if 'numlvs' is zero or alloc_lvn() fails, neither is
initialized, but are used anyway if alloc_pvd() succeeds after it.
So, make the alloc_pvd() call conditional on their initialization.
This has been hit when attaching an apparently corrupted/stressed
AIX LUN, misleading the kernel to pr_warn() invalid data and hang.

block: bio_iov_iter_get_pages: pin more pages for multi-segment IOs
bio_iov_iter_get_pages() currently only adds pages for the next non-zero
segment from the iov_iter to the bio. That's suboptimal for callers,
which typically try to pin as many pages as fit into the bio. This patch
converts the current bio_iov_iter_get_pages() into a static helper, and
introduces a new helper that allocates as many pages as
1) fit into the bio,
2) are present in the iov_iter,
3) and can be pinned by MM.
Error is returned only if zero pages could be pinned. Because of 3), a
zero return value doesn't necessarily mean all pages have been pinned.
Callers that have to pin every page in the iov_iter must still call this
function in a loop (this is currently the case).
This change matters most for __blkdev_direct_IO_simple(), which calls
bio_iov_iter_get_pages() only once. If it obtains less pages than
requested, it returns a "short write" or "short read", and
__generic_file_write_iter() falls back to buffered writes, which may
lead to data corruption.

block: bio_iov_iter_get_pages: fix size of last iovec
If the last page of the bio is not "full", the length of the last
vector slot needs to be corrected. This slot has the index
(bio->bi_vcnt - 1), but only in bio->bi_io_vec. In the "bv" helper
array, which is shifted by the value of bio->bi_vcnt at function
invocation, the correct index is (nr_pages - 1).

block: simplify bio_check_pages_dirty
bio_check_pages_dirty currently inviolates the invariant that bv_page of a bio_vec inside bi_vcnt shouldn't be zero, and that is going to become really annoying with multpath biovecs. Fortunately there isn't any all that good reason for it - once we decide to defer freeing the bio to a workqueue holding onto a few additional pages isn't really an issue anymore. So just check if there is a clean page that needs dirtying in the first path, and do a second pass to free them if there was none, while the cache is still hot. Also use the chance to micro-optimize bio_dirty_fn a bit by not saving irq state - we know we are called from a workqueue.

blk-mq: issue directly if hw queue isn't busy in case of 'none'
In case of 'none' io scheduler, when hw queue isn't busy, it isn't necessary to enqueue request to sw queue and dequeue it from sw queue because request may be submitted to hw queue asap without extra cost, meantime there shouldn't be much request in sw queue, and we don't need to worry about effect on IO merge. There are still some single hw queue SCSI HBAs(HPSA, megaraid_sas, ...) which may connect high performance devices, so 'none' is often required for obtaining good performance.

This is because we truncate the current time when saving it in our bio, but I was using the raw current time to subtract from. So once the box had been up a certain amount of time it would appear as if our IO's were taking several years to complete. Fix this by truncating the current time so it matches the issue time.

bsg: remove read/write support
The code poses a security risk due to user memory access in ->release and had an API that can't be used reliably. As far as we know it was never used for real, but if that turns out wrong we'll have to revert this commit and come up with a band aid. Jann Horn did look software archives for users of this interface, and the only users found were example code in sg3_utils, and optional support in an optional module of the tgt user space iscsi target, which looks like a proof of concept extension of the /dev/sg read/write support. Tony Battersby chimes in that the code is basically unsafe to use in general: The read/write interface on /dev/bsg is impossible to use safely because the list of completed commands is per-device (bd->done_list) rather than per-fd like it is with /dev/sg. So if program A and program B are both using the write/read interface on the same bsg device, then their command responses will get mixed up, and program A will read() some command results from program B and vice versa. So no, I don't use read/write on /dev/bsg. From a security standpoint, it should definitely be fixed or removed.

block: introduce blk-iolatency io controller
Current IO controllers for the block layer are less than ideal for our use case. The io.max controller is great at hard limiting, but it is not work conserving. This patch introduces io.latency. You provide a latency target for your group and we monitor the io in short windows to make sure we are not exceeding those latency targets. This makes use of the rq-qos infrastructure and works much like the wbt stuff. There are a few differences from wbt - It's bio based, so the latency covers the whole block layer in addition to the actual io. - We will throttle all IO types that comes in here if we need to. - We use the mean latency over the 100ms window. This is because writes can be particularly fast, which could give us a false sense of the impact of other workloads on our protected workload. - By default there's no throttling, we set the queue_depth to INT_MAX so that we can have as many outstanding bio's as we're allowed to. Only at throttle time do we pay attention to the actual queue depth. - We backcharge cgroups for root cg issued IO and induce artificial delays in order to deal with cases like metadata only or swap heavy workloads. In testing this has worked out relatively well. Protected workloads will throttle noisy workloads down to 1 io at time if they are doing normal IO on their own, or induce up to a 1 second delay per syscall if they are doing a lot of root issued IO (metadata/swap IO). Our testing has revolved mostly around our production web servers where we have hhvm (the web server application) in a protected group and everything else in another group. We see slightly higher requests per second (RPS) on the test tier vs the control tier, and much more stable RPS across all machines in the test tier vs the control tier. Another test we run is a slow memory allocator in the unprotected group. Before this would eventually push us into swap and cause the whole box to die and not recover at all. With these patches we see slight RPS drops (usually 10-15%) before the memory consumer is properly killed and things recover within seconds.

blkcg: add generic throttling mechanism
Since IO can be issued from literally anywhere it's almost impossible to do throttling without having some sort of adverse effect somewhere else in the system because of locking or other dependencies. The best way to solve this is to do the throttling when we know we aren't holding any other kernel resources. Do this by tracking throttling in a per-blkg basis, and if we require throttling flag the task that it needs to check before it returns to user space and possibly sleep there. This is to address the case where a process is doing work that is generating IO that can't be throttled, whether that is directly with a lot of REQ_META IO, or indirectly by allocating so much memory that it is swamping the disk with REQ_SWAP. We can't use task_add_work as we don't want to induce a memory allocation in the IO path, so simply saving the request queue in the task and flagging it to do the notify_resume thing achieves the same result without the overhead of a memory allocation.

block: add bi_blkg to the bio for cgroups
Currently io.low uses a bi_cg_private to stash its private data for the blkg, however other blkcg policies may want to use this as well. Since we can get the private data out of the blkg, move this to bi_blkg in the bio and make it generic, then we can use bio_associate_blkg() to attach the blkg to the bio. Theoretically we could simply replace the bi_css with this since we can get to all the same information from the blkg, however you have to lookup the blkg, so for example wbc_init_bio() would have to lookup and possibly allocate the blkg for the css it was trying to attach to the bio. This could be problematic and result in us either not attaching the css at all to the bio, or falling back to the root blkcg if we are unable to allocate the corresponding blkg. So for now do this, and in the future if possible we could just replace the bi_css with bi_blkg and update the helpers to do the correct translation.

blk-mq: avoid to synchronize rcu inside blk_cleanup_queue()
SCSI probing may synchronously create and destroy a lot of request_queues
for non-existent devices. Any synchronize_rcu() in queue creation or
destroy path may introduce long latency during booting, see detailed
description in comment of blk_register_queue().
This patch removes one synchronize_rcu() inside blk_cleanup_queue()
for this case, commit c2856ae2f315d75(blk-mq: quiesce queue before freeing queue)
needs synchronize_rcu() for implementing blk_mq_quiesce_queue(), but
when queue isn't initialized, it isn't necessary to do that since
only pass-through requests are involved, no original issue in
scsi_execute() at all.
Without this patch and previous one, it may take more 20+ seconds for
virtio-scsi to complete disk probe. With the two patches, the time becomes
less than 100ms.

blk-mq: remove synchronize_rcu() from blk_mq_del_queue_tag_set()
We have to remove synchronize_rcu() from blk_queue_cleanup(),
otherwise long delay can be caused during lun probe. For removing
it, we have to avoid to iterate the set->tag_list in IO path, eg,
blk_mq_sched_restart().
This patch reverts 5b79413946d (Revert "blk-mq: don't handle
TAG_SHARED in restart"). Given we have fixed enough IO hang issue,
and there isn't any reason to restart all queues in one tags any more,
see the following reasons:
1) blk-mq core can deal with shared-tags case well via blk_mq_get_driver_tag(),
which can wake up queues waiting for driver tag.
2) SCSI is a bit special because it may return BLK_STS_RESOURCE if queue,
target or host is ready, but SCSI built-in restart can cover all these well,
see scsi_end_request(), queue will be rerun after any request initiated from
this host/target is completed.
In my test on scsi_debug(8 luns), this patch may improve IOPS by 20% ~ 30%
when running I/O on these 8 luns concurrently.

blk-mq: introduce new lock for protecting hctx->dispatch_wait
Now hctx->lock is only acquired when adding hctx->dispatch_wait to
one wait queue, but not held when removing it from the wait queue.
IO hang can be observed easily if SCHED RESTART is disabled, that means
now RESTART exits just for fixing the issue in blk_mq_mark_tag_wait().
This patch fixes the issue by introducing hctx->dispatch_wait_lock and
holding it for removing hctx->dispatch_wait in blk_mq_dispatch_wake(),
since we need to avoid acquiring hctx->lock in irq context.

block, bfq: give a better name to bfq_bfqq_may_idle
The actual goal of the function bfq_bfqq_may_idle is to tell whether it is better to perform device idling (more precisely: I/O-dispatch plugging) for the input bfq_queue, either to boost throughput or to preserve service guarantees.

block, bfq: fix service being wrongly set to zero in case of preemption
If - a bfq_queue Q preempts another queue, because one request of Q arrives in time, - but, after this preemption, Q is not the queue that is set in service, then Q->entity.service is set to 0 when Q is eventually set in service. But Q should have continued receiving service with its old budget (which is why preemption has occurred) and its old service. This commit addresses this issue by resetting service on queue real expiration.

block, bfq: do not expire a queue that will deserve dispatch plugging
For some bfq_queues, BFQ plugs I/O dispatching when the queue becomes idle, and keeps the plug until a new request of the queue arrives, or a timeout fires. BFQ does so either to boost throughput or to preserve service guarantees for the queue. More precisely, for such a queue, plugging starts when the queue happens to have either no request enqueued, or no request in flight, that is, no request already dispatched but not yet completed. On the opposite end, BFQ may happen to expire a queue with no request enqueued, without doing any plugging, if the queue still has some request in flight. Unfortunately, such a premature expiration causes the queue to lose its chance to enjoy dispatch plugging a moment later, i.e., when its in-flight requests finally get completed. This breaks service guarantees for the queue. This commit prevents BFQ from expiring an empty queue if the latter still has in-flight requests.

block, bfq: add/remove entity weights correctly
To keep I/O throughput high as often as possible, BFQ performs I/O-dispatch plugging (aka device idling) only when beneficial exactly for throughput, or when needed for service guarantees (low latency, fairness). An important case where the latter condition holds is when the scenario is 'asymmetric' in terms of weights: i.e., when some bfq_queue or whole group of queues has a higher weight, and thus has to receive more service, than other queues or groups. Without dispatch plugging, lower-weight queues/groups may unjustly steal bandwidth to higher-weight queues/groups. To detect asymmetric scenarios, BFQ checks some sufficient conditions. One of these conditions is that active groups have different weights. BFQ controls this condition by maintaining a special set of unique weights of active groups (group_weights_tree). To this purpose, in the function bfq_active_insert/bfq_active_extract BFQ adds/removes the weight of a group to/from this set. Unfortunately, the function bfq_active_extract may happen to be invoked also for a group that is still active (to preserve the correct update of the next queue to serve, see comments in function bfq_no_longer_next_in_service() for details). In this case, removing the weight of the group makes the set group_weights_tree inconsistent. Service-guarantee violations follow. This commit addresses this issue by moving group_weights_tree insertions from their previous location (in bfq_active_insert) into the function __bfq_activate_entity, and by moving group_weights_tree extractions from bfq_active_extract to when the entity that represents a group remains throughly idle, i.e., with no request either enqueued or dispatched.

blk-mq: don't queue more if we get a busy return
Some devices have different queue limits depending on the type of IO. A classic case is SATA NCQ, where some commands can queue, but others cannot. If we have NCQ commands inflight and encounter a non-queueable command, the driver returns busy. Currently we attempt to dispatch more from the scheduler, if we were able to queue some commands. But for the case where we ended up stopping due to BUSY, we should not attempt to retrieve more from the scheduler. If we do, we can get into a situation where we attempt to queue a non-queueable command, get BUSY, then successfully retrieve more commands from that scheduler and queue those. This can repeat forever, starving the non-queuable command indefinitely. Fix this by NOT attempting to pull more commands from the scheduler, if we get a BUSY return. This should also be more optimal in terms of letting requests stay in the scheduler for as long as possible, if we get a BUSY due to the regular out-of-tags condition.
