2020-01-29block: don't use bio->bi_vcnt to figure out segment numberMing Lei
[ Upstream commit 1a67356e9a4829da2935dd338630a550c59c8489 ] It is wrong to use bio->bi_vcnt to figure out how many segments there are in the bio even though CLONED flag isn't set on this bio, because this bio may be splitted or advanced. So always use bio_segments() in blk_recount_segments(), and it shouldn't cause any performance loss now because the physical segment number is figured out in blk_queue_split() and BIO_SEG_VALID is set meantime since bdced438acd83ad83a6c ("block: setup bi_phys_segments after splitting").

2020-01-23block: fix an integer overflow in logical block sizeMikulas Patocka
commit ad6bf88a6c19a39fb3b0045d78ea880325dfcf15 upstream. Logical block size has type unsigned short. That means that it can be at most 32768. However, there are architectures that can run with 64k pages (for example arm64) and on these architectures, it may be possible to create block devices with 64k block size. For exmaple (run this on an architecture with 64k pages): Mount will fail with this error because it tries to read the superblock using 2-sector access: device-mapper: writecache: I/O is not aligned, sector 2, size 1024, block size 65536 EXT4-fs (dm-0): unable to read superblock This patch changes the logical block size from unsigned short to unsigned int to avoid the overflow.

2019-12-23block, bfq: add Early Queue Merge (EQM) to BFQ-v7r11 for 4.4.0Mauro Andreolini
A set of processes may happen to perform interleaved reads, i.e.,requests whose union would give rise to a sequential read pattern. There are two typical cases: in the first case, processes read fixed-size chunks of data at a fixed distance from each other, while in the second case processes may read variable-size chunks at variable distances. The latter case occurs for example with QEMU, which splits the I/O generated by the guest into multiple chunks, and lets these chunks be served by a pool of cooperating processes, iteratively assigning the next chunk of I/O to the first available process. CFQ uses actual queue merging for the first type of rocesses, whereas it uses preemption to get a sequential read pattern out of the read requests performed by the second type of processes. In the end it uses two different mechanisms to achieve the same goal: boosting the throughput with interleaved I/O. This patch introduces Early Queue Merge (EQM), a unified mechanism to get a sequential read pattern with both types of processes. The main idea is checking newly arrived requests against the next request of the active queue both in case of actual request insert and in case of request merge. By doing so, both the types of processes can be handled by just merging their queues. EQM is then simpler and more compact than the pair of mechanisms used in CFQ. Finally, EQM also preserves the typical low-latency properties of BFQ, by properly restoring the weight-raising state of a queue when it gets back to a non-merged state.

2019-12-23block: introduce the BFQ-v7r11 I/O sched for 4.4.0Paolo Valente
The general structure is borrowed from CFQ, as much of the code for handling I/O contexts. Over time, several useful features have been ported from CFQ as well (details in the changelog in README.BFQ). A (bfq_)queue is associated to each task doing I/O on a device, and each time a scheduling decision has to be made a queue is selected and served until it expires. - Slices are given in the service domain: tasks are assigned budgets, measured in number of sectors. Once got the disk, a task must however consume its assigned budget within a configurable maximum time (by default, the maximum possible value of the budgets is automatically computed to comply with this timeout). This allows the desired latency vs "throughput boosting" tradeoff to be set. - Budgets are scheduled according to a variant of WF2Q+, implemented using an augmented rb-tree to take eligibility into account while preserving an O(log N) overall complexity. - A low-latency tunable is provided; if enabled, both interactive and soft real-time applications are guaranteed a very low latency. - Latency guarantees are preserved also in the presence of NCQ. - Also with flash-based devices, a high throughput is achieved while still preserving latency guarantees. - BFQ features Early Queue Merge (EQM), a sort of fusion of the cooperating-queue-merging and the preemption mechanisms present in CFQ. EQM is in fact a unified mechanism that tries to get a sequential read pattern, and hence a high throughput, with any set of processes performing interleaved I/O over a contiguous sequence of sectors. - BFQ supports full hierarchical scheduling, exporting a cgroups interface. Since each node has a full scheduler, each group can be assigned its own weight. - If the cgroups interface is not used, only I/O priorities can be assigned to processes, with ioprio values mapped to weights with the relation weight = IOPRIO_BE_NR - ioprio. - ioprio classes are served in strict priority order, i.e., lower priority queues are not served as long as there are higher priority queues. Among queues in the same class the bandwidth is distributed in proportion to the weight of each queue.

Update Kconfig.iosched and do the related Makefile changes to include kernel configuration options for BFQ. Also increase the number of policies supported by the blkio controller so that BFQ can add its own.

2019-12-23cfq: Give a chance to arm slice idle timer in case of group_idleRitesh Harjani
In below scenario blkio cgroup does not work as per their assigned weights :- 1. When the underlying device is nonrotational with a single HW queue with depth of > 5 2. When the use case is forming two blkio cgroups cg1(weight 1000) & cg2(wight 100) and two processes(file1 and file2) doing sync IO in their respective blkio cgroups. For above usecase result of fio (without this patch):- file1: (groupid=0, jobs=1): err= 0: pid=685: Thu Jan 1 19:41:49 1970 write: IOPS=1315, BW=41.1MiB/s (43.1MB/s)(1024MiB/24906msec) <...> file2: (groupid=0, jobs=1): err= 0: pid=686: Thu Jan 1 19:41:49 1970 write: IOPS=1295, BW=40.5MiB/s (42.5MB/s)(1024MiB/25293msec) <...> // both the process BW is equal even though they belong to different cgroups with weight of 1000(cg1) and 100(cg2) In above case as soon as the request from cg1 is completed and even though it is provided with higher slice_idle=10, because of CFQ algorithm when the driver tries to fetch the request, CFQ expires this group without providing any idle time nor weight priority and schedules another cfq group (in this case cg2). And thus both cfq groups(cg1 & cg2) keep alternating to get the disk time and hence loses the cgroup weight based scheduling. Below patch gives a chance to cfq algorithm (cfq_arm_slice_timer) to arm the slice timer in case group_idle is enabled. With this patch result of fio(for above usecase) :- file1: (groupid=0, jobs=1): err= 0: pid=690: Thu Jan 1 00:06:08 1970 write: IOPS=1706, BW=53.3MiB/s (55.9MB/s)(1024MiB/19197msec) <..> file2: (groupid=0, jobs=1): err= 0: pid=691: Thu Jan 1 00:06:08 1970 write: IOPS=1043, BW=32.6MiB/s (34.2MB/s)(1024MiB/31401msec) <..> // In this processes BW is as per their respective cgroups weight.

commit 8962842ca5abdcf98e22ab3b2b45a103f0408b95 upstream. It is reported that sysfs buffer overflow can be triggered if the system has too many CPU cores(>841 on 4K PAGE_SIZE) when showing CPUs of hctx via /sys/block/$DEV/mq/$N/cpu_list. Use snprintf to avoid the potential buffer overflow. This version doesn't change the attribute format, and simply stops showing CPU numbers if the buffer is going to overflow.

2019-08-11block: blk_init_allocated_queue() set q->fq as NULL in the fail casexiao jin
commit 54648cf1ec2d7f4b6a71767799c45676a138ca24 upstream. 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().

2019-04-27block: do not leak memory in bio_copy_user_iov()Jérôme Glisse
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.

2019-01-23UPSTREAM: mm: don't cap request size based on read-ahead settingJens Axboe
We ran into a funky issue, where someone doing 256K buffered reads saw 128K requests at the device level. Turns out it is read-ahead capping the request size, since we use 128K as the default setting. This doesn't make a lot of sense - if someone is issuing 256K reads, they should see 256K reads, regardless of the read-ahead setting, if the underlying device can support a 256K read in a single command. This patch introduces a bdi hint, io_pages. This is the soft max IO size for the lower level, I've hooked it up to the bdev settings here. Read-ahead is modified to issue the maximum of the user request size, and the read-ahead max size, but capped to the max request size on the device side. The latter is done to avoid reading ahead too much, if the application asks for a huge read. With this patch, the kernel behaves like the application expects.

2018-09-19partitions/aix: fix usage of uninitialized lv_info and lvname structuresMauricio Faria de Oliveira
[ Upstream commit 14cb2c8a6c5dae57ee3e2da10fa3db2b9087e39e ] 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.

2018-09-19block,blkcg: use __GFP_NOWARN for best-effort allocations in blkcgTejun Heo
commit e00f4f4d0ff7e13b9115428a245b49108d625f09 upstream. blkcg allocates some per-cgroup data structures with GFP_NOWAIT and when that fails falls back to operations which aren't specific to the cgroup. Occassional failures are expected under pressure and falling back to non-cgroup operation is the right thing to do. Unfortunately, I forgot to add __GFP_NOWARN to these allocations and these expected failures end up creating a lot of noise. Add __GFP_NOWARN.

2018-09-19cfq: Give a chance for arming slice idle timer in case of group_idleRitesh Harjani
commit b3193bc0dca9bb69c8ba1ec1a318105c76eb4172 upstream. In below scenario blkio cgroup does not work as per their assigned weights :- 1. When the underlying device is nonrotational with a single HW queue with depth of >= CFQ_HW_QUEUE_MIN 2. When the use case is forming two blkio cgroups cg1(weight 1000) & cg2(wight 100) and two processes(file1 and file2) doing sync IO in their respective blkio cgroups. For above usecase result of fio (without this patch):- file1: (groupid=0, jobs=1): err= 0: pid=685: Thu Jan 1 19:41:49 1970 write: IOPS=1315, BW=41.1MiB/s (43.1MB/s)(1024MiB/24906msec) <...> file2: (groupid=0, jobs=1): err= 0: pid=686: Thu Jan 1 19:41:49 1970 write: IOPS=1295, BW=40.5MiB/s (42.5MB/s)(1024MiB/25293msec) <...> // both the process BW is equal even though they belong to diff. cgroups with weight of 1000(cg1) and 100(cg2) In above case (for non rotational NCQ devices), as soon as the request from cg1 is completed and even though it is provided with higher set_slice=10, because of CFQ algorithm when the driver tries to fetch the request, CFQ expires this group without providing any idle time nor weight priority and schedules another cfq group (in this case cg2). And thus both cfq groups(cg1 & cg2) keep alternating to get the disk time and hence loses the cgroup weight based scheduling. Below patch gives a chance to cfq algorithm (cfq_arm_slice_timer) to arm the slice timer in case group_idle is enabled. In case if group_idle is also not required (including for nonrotational NCQ drives), we need to explicitly set group_idle = 0 from sysfs for such cases. With this patch result of fio(for above usecase) :- file1: (groupid=0, jobs=1): err= 0: pid=690: Thu Jan 1 00:06:08 1970 write: IOPS=1706, BW=53.3MiB/s (55.9MB/s)(1024MiB/19197msec) <..> file2: (groupid=0, jobs=1): err= 0: pid=691: Thu Jan 1 00:06:08 1970 write: IOPS=1043, BW=32.6MiB/s (34.2MB/s)(1024MiB/31401msec) <..> // In this processes BW is as per their respective cgroups weight.

2018-07-25block: do not use interruptible wait anywhereAlan Jenkins
commit 1dc3039bc87ae7d19a990c3ee71cfd8a9068f428 upstream. When blk_queue_enter() waits for a queue to unfreeze, or unset the PREEMPT_ONLY flag, do not allow it to be interrupted by a signal. The PREEMPT_ONLY flag was introduced later in commit 3a0a529971ec ("block, scsi: Make SCSI quiesce and resume work reliably"). Note the SCSI device is resumed asynchronously, i.e. after un-freezing userspace tasks. So that commit exposed the bug as a regression in v4.15. A mysterious SIGBUS (or -EIO) sometimes happened during the time the device was being resumed. Most frequently, there was no kernel log message, and we saw Xorg or Xwayland killed by SIGBUS.[1] [1] E.g. https://bugzilla.redhat.com/show_bug.cgi?id=1553979 Without this fix, I get an IO error in this test: # dd if=/dev/sda of=/dev/null iflag=direct & \ while killall -SIGUSR1 dd; do sleep 0.1; done & \ echo mem > /sys/power/state ; \ sleep 5; killall dd # stop after 5 seconds The interruptible wait was added to blk_queue_enter in commit 3ef28e83ab15 ("block: generic request_queue reference counting"). Before then, the interruptible wait was only in blk-mq, but I don't think it could ever have been correct.

[ Upstream commit 8ab0b7dc73e1b3e2987d42554b2bff503f692772 ] HW queues may be unmapped in some cases, such as blk_mq_update_nr_hw_queues(), then we need to check it before calling blk_mq_tag_idle(), otherwise the following kernel oops can be triggered, so fix it by checking if the hw queue is unmapped since it doesn't make sense to idle the tags any more after hw queues are unmapped.

2018-04-13blk-mq: NVMe 512B/4K+T10 DIF/DIX format returns I/O error on dd with split opWen Xiong
[ Upstream commit f36ea50ca0043e7b1204feaf1d2ba6bd68c08d36 ] When formatting NVMe to 512B/4K + T10 DIf/DIX, dd with split op returns "Input/output error". Looks block layer split the bio after calling bio_integrity_prep(bio). This patch fixes the issue. Below is how we debug this issue: (1)format nvme to 4K block # size with type 2 DIF (2)dd with block size bigger than 1024k. oflag=direct dd: error writing '/dev/nvme0n1': Input/output error We added some debug code in nvme device driver.

2018-04-08partitions/msdos: Unable to mount UFS 44bsd partitionsRichard Narron
commit 5f15684bd5e5ef39d4337988864fec8012471dda upstream. UFS partitions from newer versions of FreeBSD 10 and 11 use relative addressing for their subpartitions. But older versions of FreeBSD still use absolute addressing just like OpenBSD and NetBSD. Instead of simply testing for a FreeBSD partition, the code needs to also test if the starting offset of the C subpartition is zero. https://bugzilla.kernel.org/show_bug.cgi?id=197733 Signed-off-by: Richard Narron <comet.berkeley@gmail.com> Signed-off-by: Jens Axboe <axboe@kernel.dk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
