block, bfq: fix uaf for bfqq in bic_set_bfqq()
[ Upstream commit b600de2d7d3a16f9007fad1bdae82a3951a26af2 ]
After commit 64dc8c732f5c ("block, bfq: fix possible uaf for 'bfqq->bic'"),
bic->bfqq will be accessed in bic_set_bfqq(), however, in some context
bic->bfqq will be freed, and bic_set_bfqq() is called with the freed
bic->bfqq.
Fix the problem by always freeing bfqq after bic_set_bfqq().

block, bfq: fix uaf for bfqq in bfq_exit_icq_bfqq
[ Upstream commit 246cf66e300b76099b5dbd3fdd39e9a5dbc53f02 ]
Commit 64dc8c732f5c ("block, bfq: fix possible uaf for 'bfqq->bic'")
will access 'bic->bfqq' in bic_set_bfqq(), however, bfq_exit_icq_bfqq()
can free bfqq first, and then call bic_set_bfqq(), which will cause uaf.
Fix the problem by moving bfq_exit_bfqq() behind bic_set_bfqq().

[ Upstream commit 64dc8c732f5c2b406cc752e6aaa1bd5471159cab ] Our test report a uaf for 'bfqq->bic' in 5.10: ================================================================== BUG: KASAN: use-after-free in bfq_select_queue+0x378/0xa30 CPU: 6 PID: 2318352 Comm: fsstress Kdump: loaded Not tainted 5.10.0-60.18.0.50.h602.kasan.eulerosv2r11.x86_64 #1 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.12.1-0-ga5cab58-20220320_160524-szxrtosci10000 04/01/2014 Call Trace: bfq_select_queue+0x378/0xa30 bfq_dispatch_request+0xe8/0x130 blk_mq_do_dispatch_sched+0x62/0xb0 __blk_mq_sched_dispatch_requests+0x215/0x2a0 blk_mq_sched_dispatch_requests+0x8f/0xd0 __blk_mq_run_hw_queue+0x98/0x180 __blk_mq_delay_run_hw_queue+0x22b/0x240 blk_mq_run_hw_queue+0xe3/0x190 blk_mq_sched_insert_requests+0x107/0x200 blk_mq_flush_plug_list+0x26e/0x3c0 blk_finish_plug+0x63/0x90 __iomap_dio_rw+0x7b5/0x910 iomap_dio_rw+0x36/0x80 ext4_dio_read_iter+0x146/0x190 [ext4] ext4_file_read_iter+0x1e2/0x230 [ext4] new_sync_read+0x29f/0x400 vfs_read+0x24e/0x2d0 ksys_read+0xd5/0x1b0 do_syscall_64+0x33/0x40 entry_SYSCALL_64_after_hwframe+0x61/0xc6 Commit 3bc5e683c67d ("bfq: Split shared queues on move between cgroups") changes that move process to a new cgroup will allocate a new bfqq to use, however, the old bfqq and new bfqq can point to the same bic: 1) Initial state, two process with io in the same cgroup. Process 1 Process 2 (BIC1) (BIC2) | Λ | Λ | | | | V | V | bfqq1 bfqq2 2) bfqq1 is merged to bfqq2. Process 1 Process 2 (BIC1) (BIC2) | | \-------------\| V bfqq1 bfqq2(coop) 3) Process 1 exit, then issue new io(denoce IOA) from Process 2. (BIC2) | Λ | | V | bfqq2(coop) 4) Before IOA is completed, move Process 2 to another cgroup and issue io. Process 2 (BIC2) Λ |\--------------\ | V bfqq2 bfqq3 Now that BIC2 points to bfqq3, while bfqq2 and bfqq3 both point to BIC2. If all the requests are completed, and Process 2 exit, BIC2 will be freed while there is no guarantee that bfqq2 will be freed before BIC2. Fix the problem by clearing bfqq->bic while bfqq is detached from bic.

bfq: fix waker_bfqq inconsistency crash
[ Upstream commit a1795c2ccb1e4c49220d2a0d381540024d71647c ]
This fixes crashes in bfq_add_bfqq_busy due to waker_bfqq being NULL,
but woken_list_node still being hashed. This would happen when
bfq_init_rq() expects a brand new allocated queue to be returned from
bfq_get_bfqq_handle_split() and unconditionally updates waker_bfqq
without resetting woken_list_node. Since we can always return oom_bfqq
when attempting to allocate, we cannot assume waker_bfqq starts as NULL.
Avoid setting woken_bfqq for oom_bfqq entirely, as it's not useful.
Crashes would have a stacktrace like:
[160595.656560] bfq_add_bfqq_busy+0x110/0x1ec
[160595.661142] bfq_add_request+0x6bc/0x980

[160595.716272] do_read_fault+0xe0/0x1f0
[160595.720487] do_fault+0x40/0x1c8
Tested by injecting random failures into bfq_get_queue, crashes go away
completely.

block, bfq: protect 'bfqd->queued' by 'bfqd->lock'
commit 181490d5321806e537dc5386db5ea640b826bf78 upstream. If bfq_schedule_dispatch() is called from bfq_idle_slice_timer_body(), then 'bfqd->queued' is read without holding 'bfqd->lock'. This is wrong since it can be wrote concurrently. Fix the problem by holding 'bfqd->lock' in such case.

bfq: Get rid of __bio_blkcg() usage
commit 4e54a2493e582361adc3bfbf06c7d50d19d18837 upstream.
BFQ usage of __bio_blkcg() is a relict from the past. Furthermore if bio
would not be associated with any blkcg, the usage of __bio_blkcg() in
BFQ is prone to races with the task being migrated between cgroups as
__bio_blkcg() calls at different places could return different blkcgs.
Convert BFQ to the new situation where bio->bi_blkg is initialized in
bio_set_dev() and thus practically always valid. This allows us to save
blkcg_gq lookup and noticeably simplify the code.

bfq: Remove pointless bfq_init_rq() calls
commit 5f550ede5edf846ecc0067be1ba80514e6fe7f8e upstream. We call bfq_init_rq() from request merging functions where requests we get should have already gone through bfq_init_rq() during insert and anyway we want to do anything only if the request is already tracked by BFQ. So replace calls to bfq_init_rq() with RQ_BFQQ() instead to simply skip requests untracked by BFQ. We move bfq_init_rq() call in bfq_insert_request() a bit earlier to cover request merging and thus can transfer FIFO position in case of a merge.

bfq: Drop pointless unlock-lock pair
commit fc84e1f941b91221092da5b3102ec82da24c5673 upstream. In bfq_insert_request() we unlock bfqd->lock only to call trace_block_rq_insert() and then lock bfqd->lock again. This is really pointless since tracing is disabled if we really care about performance and even if the tracepoint is enabled, it is a quick call.

bfq: Update cgroup information before merging bio
commit ea591cd4eb270393810e7be01feb8fde6a34fbbe upstream.
When the process is migrated to a different cgroup (or in case of
writeback just starts submitting bios associated with a different
cgroup) bfq_merge_bio() can operate with stale cgroup information in
bic. Thus the bio can be merged to a request from a different cgroup or
it can result in merging of bfqqs for different cgroups or bfqqs of
already dead cgroups and causing possible use-after-free issues. Fix the
problem by updating cgroup information in bfq_merge_bio().

bfq: Split shared queues on move between cgroups
commit 3bc5e683c67d94bd839a1da2e796c15847b51b69 upstream.
When bfqq is shared by multiple processes it can happen that one of the
processes gets moved to a different cgroup (or just starts submitting IO
for different cgroup). In case that happens we need to split the merged
bfqq as otherwise we will have IO for multiple cgroups in one bfqq and
we will just account IO time to wrong entities etc.
Similarly if the bfqq is scheduled to merge with another bfqq but the
merge didn't happen yet, cancel the merge as it need not be valid
anymore.

bfq: Avoid merging queues with different parents
commit c1cee4ab36acef271be9101590756ed0c0c374d9 upstream.
It can happen that the parent of a bfqq changes between the moment we
decide two queues are worth to merge (and set bic->stable_merge_bfqq)
and the moment bfq_setup_merge() is called. This can happen e.g. because
the process submitted IO for a different cgroup and thus bfqq got
reparented. It can even happen that the bfqq we are merging with has
parent cgroup that is already offline and going to be destroyed in which
case the merge can lead to use-after-free issues such as:

commit 70456e5210f40ffdb8f6d905acfdcec5bd5fad9e upstream.
bfq_setup_cooperator() can mark bic as stably merged even though it
decides to not merge its bfqqs (when bfq_setup_merge() returns NULL).
Make sure to mark bic as stably merged only if we are really going to
merge bfqqs.

bfq: Allow current waker to defend against a tentative one
[ Upstream commit c5ac56bb6110e42e79d3106866658376b2e48ab9 ]
The code in bfq_check_waker() ignores wake up events from the current
waker. This makes it more likely we select a new tentative waker
although the current one is generating more wake up events. Treat
current waker the same way as any other process and allow it to reset
the waker detection logic.

bfq: Relax waker detection for shared queues
[ Upstream commit f950667356ce90a41b446b726d4595a10cb65415 ]
Currently we look for waker only if current queue has no requests. This
makes sense for bfq queues with a single process however for shared
queues when there is a larger number of processes the condition that
queue has no requests is difficult to meet because often at least one
process has some request in flight although all the others are waiting
for the waker to do the work and this harms throughput. Relax the "no
queued request for bfq queue" condition to "the current task has no
queued requests yet". For this, we also need to start tracking number of
requests in flight for each task.
This patch (together with the following one) restores the performance
for dbench with 128 clients that regressed with commit c65e6fd460b4
("bfq: Do not let waker requests skip proper accounting") because
this commit makes requests of wakers properly enter BFQ queues and thus
these queues become ineligible for the old waker detection logic.
Dbench results:
Vanilla 5.18-rc3 5.18-rc3 + revert 5.18-rc3 patched
Mean 1237.36 ( 0.00%) 950.16 * 23.21%* 988.35 * 20.12%*
Numbers are time to complete workload so lower is better.

block/wbt: fix negative inflight counter when remove scsi device
commit e92bc4cd34de2ce454bdea8cd198b8067ee4e123 upstream.
Now that we disable wbt by set WBT_STATE_OFF_DEFAULT in
wbt_disable_default() when switch elevator to bfq. And when
we remove scsi device, wbt will be enabled by wbt_enable_default.
If it become false positive between wbt_wait() and wbt_track()
when submit write request.
The following is the scenario that triggered the problem.
T1 T2 T3
elevator_switch_mq
bfq_init_queue
wbt_disable_default <= Set
rwb->enable_state (OFF)
Submit_bio
blk_mq_make_request
rq_qos_throttle
<= rwb->enable_state (OFF)
scsi_remove_device
sd_remove
del_gendisk
blk_unregister_queue
elv_unregister_queue
wbt_enable_default
<= Set rwb->enable_state (ON)
q_qos_track
<= rwb->enable_state (ON)
^^^^^^ this request will mark WBT_TRACKED without inflight add and will
lead to drop rqw->inflight to -1 in wbt_done() which will trigger IO hung.
Fix this by move wbt_enable_default() from elv_unregister to
bfq_exit_queue(). Only re-enable wbt when bfq exit.

block, bfq: honor already-setup queue merges
The function bfq_setup_merge prepares the merging between two bfq_queues, say bfqq and new_bfqq. To this goal, it assigns bfqq->new_bfqq = new_bfqq. Then, each time some I/O for bfqq arrives, the process that generated that I/O is disassociated from bfqq and associated with new_bfqq (merging is actually a redirection). In this respect, bfq_setup_merge increases new_bfqq->ref in advance, adding the number of processes that are expected to be associated with new_bfqq. Unfortunately, the stable-merging mechanism interferes with this setup. After bfqq->new_bfqq has been set by bfq_setup_merge, and before all the expected processes have been associated with bfqq->new_bfqq, bfqq may happen to be stably merged with a different queue than the current bfqq->new_bfqq. In this case, bfqq->new_bfqq gets changed. So, some of the processes that have been already accounted for in the ref counter of the previous new_bfqq will not be associated with that queue. This creates an unbalance, because those references will never be decremented. This commit fixes this issue by reestablishing the previous, natural behaviour: once bfqq->new_bfqq has been set, it will not be changed until all expected redirections have occurred.

block: fix default IO priority handling
The default IO priority is the best effort (BE) class with the normal priority level IOPRIO_NORM (4). However, get_task_ioprio() returns IOPRIO_CLASS_NONE/IOPRIO_NORM as the default priority and get_current_ioprio() returns IOPRIO_CLASS_NONE/0. Let's be consistent with the defined default and have both of these functions return the default priority IOPRIO_PRIO_VALUE(IOPRIO_CLASS_BE, IOPRIO_NORM) when the user did not define another default IO priority for the task. In include/uapi/linux/ioprio.h, introduce the IOPRIO_BE_NORM macro as an alias to IOPRIO_NORM to clarify that this default level applies to the BE priotity class. In include/linux/ioprio.h, define the macro IOPRIO_DEFAULT as IOPRIO_PRIO_VALUE(IOPRIO_CLASS_BE, IOPRIO_BE_NORM) and use this new macro when setting a priority to the default.

block: Introduce IOPRIO_NR_LEVELS
The BFQ scheduler and ioprio_check_cap() both assume that the RT priority class (IOPRIO_CLASS_RT) can have up to 8 different priority levels, similarly to the BE class (IOPRIO_CLASS_iBE). This is controlled using the IOPRIO_BE_NR macro , which is badly named as the number of levels also applies to the RT class. Introduce the class independent IOPRIO_NR_LEVELS macro, defined to 8, to make things clear. Keep the old IOPRIO_BE_NR macro definition as an alias for IOPRIO_NR_LEVELS.

For a request that has a priority level equal to or larger than

defaults to setting the request new_ioprio field to IOPRIO_BE_NR. This
is not consistent with the warning and the allowed values for priority

IOPRIO_BE_NR - 1, the lowest priority level allowed.

block: return ELEVATOR_DISCARD_MERGE if possible
When merging one bio to request, if they are discard IO and the queue
supports multi-range discard, we need to return ELEVATOR_DISCARD_MERGE
because both block core and related drivers(nvme, virtio-blk) doesn't
handle mixed discard io merge(traditional IO merge together with
discard merge) well.
Fix the issue by returning ELEVATOR_DISCARD_MERGE in this situation,
so both blk-mq and drivers just need to handle multi-range discard.

bfq: Remove merged request already in bfq_requests_merged()
Currently, bfq does very little in bfq_requests_merged() and handles all the request cleanup in bfq_finish_requeue_request() called from blk_mq_free_request(). That is currently safe only because blk_mq_free_request() is called shortly after bfq_requests_merged() while bfqd->lock is still held. However to fix a lock inversion between bfqd->lock and ioc->lock, we need to call blk_mq_free_request() after dropping bfqd->lock. That would mean that already merged request could be seen by other processes inside bfq queues and possibly dispatched to the device which is wrong. So move cleanup of the request from bfq_finish_requeue_request() to bfq_requests_merged().

block, bfq: check waker only for queues with no in-flight I/O
Consider two bfq_queues, say Q1 and Q2, with Q2 empty. If a request of Q1 gets completed shortly before a new request arrives for Q2, then BFQ flags Q1 as a candidate waker for Q2. Yet, the arrival of this new request may have a different cause, in the following case. If also Q2 has requests in flight while waiting for the arrival of a new request, then the completion of its own requests may be the actual cause of the awakening of the process that sends I/O to Q2. So Q1 may be flagged wrongly as a candidate waker. This commit avoids this deceptive flagging, by disabling candidate-waker flagging for Q2, if Q2 has in-flight I/O.

block, bfq: boost throughput by extending queue-merging times
One of the methods with which bfq boosts throughput is by merging queues. One of the merging variants in bfq is the stable merge. This mechanism is activated between two queues only if they are created within a certain maximum time T1 from each other. Merging can happen soon or be delayed. In the second case, before merging, bfq needs to evaluate a throughput-boost parameter that indicates whether the queue generates a high throughput is served alone. Merging occurs when this throughput-boost is not high enough. In particular, this parameter is evaluated and late merging may occur only after at least a time T2 from the creation of the queue. Currently T1 and T2 are set to 180ms and 200ms, respectively. In this way the merging mechanism rarely occurs because time is not enough. This results in a noticeable lowering of the overall throughput with some workloads (see the example below). This commit introduces two constants bfq_activation_stable_merging and bfq_late_stable_merging in order to increase the duration of T1 and T2. Both the stable merging activation time and the late merging time are set to 600ms. This value has been experimentally evaluated using sqlite benchmark in the Phoronix Test Suite on a HDD. The duration of the benchmark before this fix was 111.02s, while now it has reached 97.02s, a better result than that of all the other schedulers.

block, bfq: fix delayed stable merge check
When attempting to schedule a merge of a given bfq_queue with the currently in-service bfq_queue or with a cooperating bfq_queue among the scheduled bfq_queues, delayed stable merge is checked for rotational or non-queueing devs. For this stable merge to be performed, some conditions must be met. If the current bfq_queue underwent some split from some merged bfq_queue, one of these conditions is that two hundred milliseconds must elapse from split, otherwise this condition is always met. Unfortunately, by mistake, time_is_after_jiffies() was written instead of time_is_before_jiffies() for this check, verifying that less than two hundred milliseconds have elapsed instead of verifying that at least two hundred milliseconds have elapsed. Fix this issue by replacing time_is_after_jiffies() with time_is_before_jiffies().

block, bfq: let also stably merged queues enjoy weight raising
Merged bfq_queues are kept out of weight-raising (low-latency) mechanisms. The reason is that these queues are usually created for non-interactive and non-soft-real-time tasks. Yet this is not the case for stably-merged queues. These queues are merged just because they are created shortly after each other. So they may easily serve the I/O of an interactive or soft-real time application, if the application happens to spawn multiple processes. To address this issue, this commits lets also stably-merged queued enjoy weight raising.

block, bfq: avoid circular stable merges
BFQ may merge a new bfq_queue, stably, with the last bfq_queue
created. In particular, BFQ first waits a little bit for some I/O to
flow inside the new queue, say Q2, if this is needed to understand
whether it is better or worse to merge Q2 with the last queue created,
say Q1. This delayed stable merge is performed by assigning
bic->stable_merge_bfqq = Q1, for the bic associated with Q1.
Yet, while waiting for some I/O to flow in Q2, a non-stable queue
merge of Q2 with Q1 may happen, causing the bic previously associated
with Q2 to be associated with exactly Q1 (bic->bfqq = Q1). After that,
Q2 and Q1 may happen to be split, and, in the split, Q1 may happen to
be recycled as a non-shared bfq_queue. In that case, Q1 may then
happen to undergo a stable merge with the bfq_queue pointed by
bic->stable_merge_bfqq. Yet bic->stable_merge_bfqq still points to
Q1. So Q1 would be merged with itself.
This commit fixes this error by intercepting this situation, and
canceling the schedule of the stable merge.

passes the hctx to ->bio_merge(). kyber_bio_merge() then gets the ctx
for the current CPU again and uses that to get the corresponding Kyber
context in the passed hctx. However, the thread may be preempted between
the two calls to blk_mq_get_ctx(), and the ctx returned the second time
may no longer correspond to the passed hctx. This "works" accidentally
most of the time, but it can cause us to read garbage if the second ctx
came from an hctx with more ctx's than the first one (i.e., if
ctx->index_hw[hctx->type] > hctx->nr_ctx).
This manifested as this UBSAN array index out of bounds error reported
by Jakub:

Only Kyber uses the hctx, so fix it by passing the request_queue to
->bio_merge() instead. BFQ and mq-deadline just use that, and Kyber can
map the queues itself to avoid the mismatch.

block, bfq: merge bursts of newly-created queues
Many throughput-sensitive workloads are made of several parallel I/O flows, with all flows generated by the same application, or more generically by the same task (e.g., system boot). The most counterproductive action with these workloads is plugging I/O dispatch when one of the bfq_queues associated with these flows remains temporarily empty. To avoid this plugging, BFQ has been using a burst-handling mechanism for years now. This mechanism has proven effective for throughput, and not detrimental for service guarantees. This commit pushes this mechanism a little bit further, basing on the following two facts. First, all the I/O flows of a the same application or task contribute to the execution/completion of that common application or task. So the performance figures that matter are total throughput of the flows and task-wide I/O latency. In particular, these flows do not need to be protected from each other, in terms of individual bandwidth or latency. Second, the above fact holds regardless of the number of flows. Putting these two facts together, this commits merges stably the bfq_queues associated with these I/O flows, i.e., with the processes that generate these IO/ flows, regardless of how many the involved processes are. To decide whether a set of bfq_queues is actually associated with the I/O flows of a common application or task, and to merge these queues stably, this commit operates as follows: given a bfq_queue, say Q2, currently being created, and the last bfq_queue, say Q1, created before Q2, Q2 is merged stably with Q1 if - very little time has elapsed since when Q1 was created - Q2 has the same ioprio as Q1 - Q2 belongs to the same group as Q1 Merging bfq_queues also reduces scheduling overhead. A fio test with ten random readers on /dev/nullb shows a throughput boost of 40%, with a quadcore. Since BFQ's execution time amounts to ~50% of the total per-request processing time, the above throughput boost implies that BFQ's overhead is reduced by more than 50%.

block, bfq: keep shared queues out of the waker mechanism
Shared queues are likely to receive I/O at a high rate. This may deceptively let them be considered as wakers of other queues. But a false waker will unjustly steal bandwidth to its supposedly woken queue. So considering also shared queues in the waking mechanism may cause more control troubles than throughput benefits. This commit keeps shared queues out of the waker-detection mechanism.

block, bfq: fix weight-raising resume with !low_latency
When the io_latency heuristic is off, bfq_queues must not start to be weight-raised. Unfortunately, by mistake, this may happen when the state of a previously weight-raised bfq_queue is resumed after a queue split. This commit fixes this error.

block, bfq: make shared queues inherit wakers
Consider a bfq_queue bfqq that is about to be merged with another bfq_queue new_bfqq. The processes associated with bfqq are cooperators of the processes associated with new_bfqq. So, if bfqq has a waker, then it is reasonable (and beneficial for throughput) to assume that all these processes will be happy to let bfqq's waker freely inject I/O when they have no I/O. So this commit makes new_bfqq inherit bfqq's waker.
