Greg Kroah-Hartman	ebbd5ac4ac	Revert "bsg-lib: don't free job in bsg_prepare_job" ... This reverts commit eb4375e196 which was commit f507b54dcc upstream. Ben reports: That function doesn't exist here (it was introduced in 4.13). Instead, this backport has modified bsg_create_job(), creating a leak. Please revert this on the 3.18, 4.4 and 4.9 stable branches. So I'm dropping it from here.

Since "block: support large requests in blk_rq_map_user_iov" we started to call it with partially drained iter; that works fine on the write side, but reads create a copy of iter for completion time.

Alden Tondettar	0fc89de6ee	partitions/efi: Fix integer overflow in GPT size calculation ... [ Upstream commit c5082b70ad ] If a GUID Partition Table claims to have more than 2**25 entries, the calculation of the partition table size in alloc_read_gpt_entries() will overflow a 32-bit integer and not enough space will be allocated for the table. Nothing seems to get written out of bounds, but later efi_partition() will read up to 32768 bytes from a 128 byte buffer, possibly OOPSing or exposing information to /proc/partitions and uevents. The problem exists on both 64-bit and 32-bit platforms. Fix the overflow and also print a meaningful debug message if the table size is too large.

Hou Tao	08229c119c	cfq-iosched: fix the delay of cfq_group's vdisktime under iops mode ... commit 5be6b75610 upstream. When adding a cfq_group into the cfq service tree, we use CFQ_IDLE_DELAY as the delay of cfq_group's vdisktime if there have been other cfq_groups already. When cfq is under iops mode, commit 9a7f38c42c ("cfq-iosched: Convert from jiffies to nanoseconds") could result in a large iops delay and lead to an abnormal io schedule delay for the added cfq_group. To fix it, we just need to revert to the old CFQ_IDLE_DELAY value: HZ / 5 when iops mode is enabled. Despite having the same value, the delay of a cfq_queue in idle class and the delay of cfq_group are different things, so I define two new macros for the delay of a cfq_group under time-slice mode and iops mode.

Ilya Dryomov	6a7620744e	block: get rid of blk_integrity_revalidate() ... commit 19b7ccf865 upstream. Commit 25520d55cd ("block: Inline blk_integrity in struct gendisk") introduced blk_integrity_revalidate(), which seems to assume ownership of the stable pages flag and unilaterally clears it if no blk_integrity profile is registered: if (bi->profile) disk->queue->backing_dev_info->capabilities |= BDI_CAP_STABLE_WRITES; else disk->queue->backing_dev_info->capabilities &= ~BDI_CAP_STABLE_WRITES; It's called from revalidate_disk() and rescan_partitions(), making it impossible to enable stable pages for drivers that support partitions and don't use blk_integrity: while the call in revalidate_disk() can be trivially worked around (see zram, which doesn't support partitions and hence gets away with zram_revalidate_disk()), rescan_partitions() can be triggered from userspace at any time. This breaks rbd, where the ceph messenger is responsible for generating/verifying CRCs. Since blk_integrity_{un,}register() "must" be used for (un)registering the integrity profile with the block layer, move BDI_CAP_STABLE_WRITES setting there. This way drivers that call blk_integrity_register() and use integrity infrastructure won't interfere with drivers that don't but still want stable pages.

Gabriel Krisman Bertazi	d7045cbf4a	blk-mq: Avoid memory reclaim when remapping queues ... commit 36e1f3d107 upstream. While stressing memory and IO at the same time we changed SMT settings, we were able to consistently trigger deadlocks in the mm system, which froze the entire machine. I think that under memory stress conditions, the large allocations performed by blk_mq_init_rq_map may trigger a reclaim, which stalls waiting on the block layer remmaping completion, thus deadlocking the system. The trace below was collected after the machine stalled, waiting for the hotplug event completion. The simplest fix for this is to make allocations in this path non-reclaimable, with GFP_NOIO. With this patch, We couldn't hit the issue anymore. This should apply on top of Jens's for-next branch cleanly. Changes since v1: - Use GFP_NOIO instead of GFP_NOWAIT.

Commit 79bd99596b ("blk: improve order of bio handling in generic_make_request()") changed current->bio_list so that it did not contain *all* of the queued bios, but only those submitted by the currently running make_request_fn. There are two places which walk the list and requeue selected bios, and others that check if the list is empty. These are no longer correct. So redefine current->bio_list to point to an array of two lists, which contain all queued bios, and adjust various code to test or walk both lists.

NeilBrown	d5986e0078	blk: improve order of bio handling in generic_make_request() ... commit 79bd99596b upstream. To avoid recursion on the kernel stack when stacked block devices are in use, generic_make_request() will, when called recursively, queue new requests for later handling. They will be handled when the make_request_fn for the current bio completes. If any bios are submitted by a make_request_fn, these will ultimately be handled seqeuntially. If the handling of one of those generates further requests, they will be added to the end of the queue. This strict first-in-first-out behaviour can lead to deadlocks in various ways, normally because a request might need to wait for a previous request to the same device to complete. This can happen when they share a mempool, and can happen due to interdependencies particular to the device. Both md and dm have examples where this happens. These deadlocks can be erradicated by more selective ordering of bios. Specifically by handling them in depth-first order. That is: when the handling of one bio generates one or more further bios, they are handled immediately after the parent, before any siblings of the parent. That way, when generic_make_request() calls make_request_fn for some particular device, we can be certain that all previously submited requests for that device have been completely handled and are not waiting for anything in the queue of requests maintained in generic_make_request(). An easy way to achieve this would be to use a last-in-first-out stack instead of a queue. However this will change the order of consecutive bios submitted by a make_request_fn, which could have unexpected consequences. Instead we take a slightly more complex approach. A fresh queue is created for each call to a make_request_fn. After it completes, any bios for a different device are placed on the front of the main queue, followed by any bios for the same device, followed by all bios that were already on the queue before the make_request_fn was called. This provides the depth-first approach without reordering bios on the same level. This, by itself, it not enough to remove all deadlocks. It just makes it possible for drivers to take the extra step required themselves. To avoid deadlocks, drivers must never risk waiting for a request after submitting one to generic_make_request. This includes never allocing from a mempool twice in the one call to a make_request_fn. A common pattern in drivers is to call bio_split() in a loop, handling the first part and then looping around to possibly split the next part. Instead, a driver that finds it needs to split a bio should queue (with generic_make_request) the second part, handle the first part, and then return. The new code in generic_make_request will ensure the requests to underlying bios are processed first, then the second bio that was split off. If it splits again, the same process happens. In each case one bio will be completely handled before the next one is attempted. With this is place, it should be possible to disable the punt_bios_to_recover() recovery thread for many block devices, and eventually it may be possible to remove it completely.

Ming Lei	21d17f1b53	blk-mq: don't complete un-started request in timeout handler ... commit 95a4960370 upstream. When iterating busy requests in timeout handler, if the STARTED flag of one request isn't set, that means the request is being processed in block layer or driver, and isn't submitted to hardware yet. In current implementation of blk_mq_check_expired(), if the request queue becomes dying, un-started requests are handled as being completed/freed immediately. This way is wrong, and can cause rq corruption or double allocation[1][2], when doing I/O and removing&resetting NVMe device at the sametime. This patch fixes several issues reported by Yi Zhang.

Mauricio Faria de Oliveira	61a153d06e	block: allow WRITE_SAME commands with the SG_IO ioctl ... [ Upstream commit 25cdb64510 ] The WRITE_SAME commands are not present in the blk_default_cmd_filter write_ok list, and thus are failed with -EPERM when the SG_IO ioctl() is executed without CAP_SYS_RAWIO capability (e.g., unprivileged users). [ sg_io() -> blk_fill_sghdr_rq() > blk_verify_command() -> -EPERM ] The problem can be reproduced with the sg_write_same command # sg_write_same --num 1 --xferlen 512 /dev/sda # # capsh --drop=cap_sys_rawio -- -c \ 'sg_write_same --num 1 --xferlen 512 /dev/sda' Write same: pass through os error: Operation not permitted # For comparison, the WRITE_VERIFY command does not observe this problem, since it is in that list: # capsh --drop=cap_sys_rawio -- -c \ 'sg_write_verify --num 1 --ilen 512 --lba 0 /dev/sda' # So, this patch adds the WRITE_SAME commands to the list, in order for the SG_IO ioctl to finish successfully: # capsh --drop=cap_sys_rawio -- -c \ 'sg_write_same --num 1 --xferlen 512 /dev/sda' # That case happens to be exercised by QEMU KVM guests with 'scsi-block' devices (qemu "-device scsi-block" [1], libvirt "<disk type='block' device='lun'>" [2]), which employs the SG_IO ioctl() and runs as an unprivileged user (libvirt-qemu). In that scenario, when a filesystem (e.g., ext4) performs its zero-out calls, which are translated to write-same calls in the guest kernel, and then into SG_IO ioctls to the host kernel, SCSI I/O errors may be observed in the guest: [...] sd 0:0:0:0: [sda] tag#0 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE [...] sd 0:0:0:0: [sda] tag#0 Sense Key : Aborted Command [current] [...] sd 0:0:0:0: [sda] tag#0 Add.

Gabriel Krisman Bertazi	d9c19f90f3	blk-mq: Always schedule hctx->next_cpu ... commit c02ebfdddb upstream. Commit 0e87e58bf6 ("blk-mq: improve warning for running a queue on the wrong CPU") attempts to avoid triggering the WARN_ON in __blk_mq_run_hw_queue when the expected CPU is dead. Problem is, in the last batch execution before round robin, blk_mq_hctx_next_cpu can schedule a dead CPU and also update next_cpu to the next alive CPU in the mask, which will trigger the WARN_ON despite the previous workaround. The following patch fixes this scenario by always scheduling the value in hctx->next_cpu. This changes the moment when we round-robin the CPU running the hctx, but it really doesn't matter, since it still executes BLK_MQ_CPU_WORK_BATCH times in a row before switching to another CPU.

Darrick J. Wong	22dd6d3566	block: invalidate the page cache when issuing BLKZEROOUT ... Patch series "fallocate for block devices", v11. This is a patchset to fix page cache coherency with BLKZEROOUT and implement fallocate for block devices. The first patch is a fix to the existing BLKZEROOUT ioctl to invalidate the page cache if the zeroing command to the underlying device succeeds. Without this patch we still have the pagecache coherence bug that's been in the kernel forever. The second patch changes the internal block device functions to reject attempts to discard or zeroout that are not aligned to the logical block size. Previously, we only checked that the start/len parameters were 512-byte aligned, which caused kernel BUG_ONs for unaligned IOs to 4k-LBA devices. The third patch creates an fallocate handler for block devices, wires up the FALLOC_FL_PUNCH_HOLE flag to zeroing-discard, and connects FALLOC_FL_ZERO_RANGE to write-same so that we can have a consistent fallocate interface between files and block devices. It also allows the combination of PUNCH_HOLE and NO_HIDE_STALE to invoke non-zeroing discard. Test cases for the new block device fallocate are now in xfstests as generic/349-351. This patch (of 3): Invalidate the page cache (as a regular O_DIRECT write would do) to avoid returning stale cache contents at a later time.

Emese Revfy	0766f788eb	latent_entropy: Mark functions with __latent_entropy ... The __latent_entropy gcc attribute can be used only on functions and variables. If it is on a function then the plugin will instrument it for gathering control-flow entropy. If the attribute is on a variable then the plugin will initialize it with random contents. The variable must be an integer, an integer array type or a structure with integer fields. These specific functions have been selected because they are init functions (to help gather boot-time entropy), are called at unpredictable times, or they have variable loops, each of which provide some level of latent entropy.
