Merge tag 'block-7.4-20261029' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux
Pull more block updates from Jens Axboe:
"Bigger than usual for an end-of-merge-window pull request, main reason
being that the MD side I had missed a pull on, and both NVMe and block
got a good pile of LLM driven fixes where some of them may as well
just go in now rather than wait a full cycle. This contains:
- NVMe fixes via Keith:
- nvme-tcp fallout from the parallel queue allocation: initialize
pf_cache_lock and the header digest before requests are set up,
and don't dereference a NULL queue->ctrl on reconnect
- nvme-fabrics queue mapping fixes: reset io_queues on reconnect,
limit each queue type to the online CPUs, and clear a poll map
with no poll queues
- nvme-tcp io_work priority inversion with send_mutex held
(Seiji), error recovery on read_sock failure and skipping TLS
control records while waiting for the ICResp (Martin B), TLS
handshake timeout validation, and an address attribute race
- nvme-rdma NULL metadata_sgl dereference with T10-PI
- nvme-pci early boot hang with the quirks parameter
- nvme-multipath ANA log bounds underflow, and an nvme-fc
discovery reference leak
- nvmet hardening: rdma inline SGL out-of-bounds write and short
connect requests, fc use-after-free in LS create connection and
teardown on admin queue failure, pci-epf transport error
reporting and SGL length checks, zns NUMD wrap, fc stale read
data, auth state and status fixes, ports list and qid_max
locking, rdma double puts and irq-safe locking, and a double
free on metadata SGL allocation failure
- nvmet fixes from Josef: big discard length truncation, NULL
derefs for PCI endpoint targets and debugfs host_traddr, stop
listening when a tcp port is removed, and don't BUG() in
nvme-loop when a scan runs beside a reset
- MD fixes via Yu Kuai:
- raid5 validation: reject too few disks, invalid reshape disks, a
per-device size below one chunk, and an inconsistent reshape
state from the superblock instead of BUG(), plus journal payload
size checks
- raid5 error path and lifetime fixes: extra_page leak and NULL
derefs in free_conf/setup_conf, draining released_stripes before
destroying the cache, RCU for the big_stripe_tree lookup, and
per-array io_unit slab names
- md core: reject v0.90 arrays with too many devices, validate
bblog_size, take reconfig_mutex when enabling PPL, fix the
mddev->private NULL deref when stopping an array under IO, and
don't hand out the array before mddev->kobj is added
- raid10 missing barrier wakeup, raid0 device count validation, a
bogus mddev_unlock() in lbs_store(), and shared helpers
- blk-mq fixes from Josef:
- don't trust the bio cookie in blk_mq_poll()
- keep tag sharing fair after a queue update
- don't bring back flags of a completed request from the timeout
handler
- honor a restarted timer
- initialize the dma state for P2P
- quiesce a queue joining a quiesced tag set
- set up and exit hctxs under tag_list_lock
- free the tag bitmaps in the SRCU callback
- blk-cgroup and friends from Josef:
- keep the old blkg while reassociating a bio
- free struct ioc after a grace period
- don't truncate v1 iops limits
- fix root io.stat on 32-bit
- don't free a blkg with its punt work queued
- flush iolatency enable_work after going offline
- pass dead group I/O counts on and make reset_stats reset them
- don't enter reclaim under rq_qos_mutex
- Other core fixes from Josef:
- a disk use-after-free in sync_bdevs()
- don't losing the status of a failed flush request
- 64-bit sector math for mac partitions
- apply the segment size to the integrity buffer
- blk-iocost: abort a weight transfer on invalid donation weights,
and publish hweights as one atomic value
- Fix a NULL deref and use-after-free in __blk_crypto_evict_key(),
reachable via dm-inlinecrypt
- Fix recursive i_rwsem locking in blkdev_write_iter(), from two
fixes for the same race landing in the window
- Advance the iterator after copy-in for SG_DXFER_TO_FROM_DEV, fixing
an infinite loop in blk_rq_map_user_iov()
- Check the open mode for LOOP_SET_STATUS in the compat ioctl
- rnbd-srv use-after-free and kobject fixes
- drbd timer and req_lock fixes
- zloop cleanups and error path fixes
- cdrom header and kernel-doc cleanups"
