add_disk_final() sets GD_NEED_PART_SCAN before calling bdev_add(),
then calls disk_scan_partitions() which sets the flag itself. The
early set is redundant and introduces a race.
Between bdev_add() and disk_scan_partitions(), concurrent openers
(multipathd, blkid, LVM) see the flag in blkdev_get_whole() and
trigger bdev_disk_changed(). When disk_scan_partitions() then runs,
it calls bdev_disk_changed() again, dropping the partitions the
concurrent opener already created before re-adding them, which can
result in transient partition disappearances.
The race is observable by inserting an msleep() between bdev_add()
and disk_scan_partitions() while running concurrent open() calls
during device bind. Without artificial delay, it manifests under
scheduling pressure during boot on systems with aggressive device
scanners (multipathd, systemd-udevd).
Therefore, do not set GD_NEED_PART_SCAN in add_disk_final(). Other
GD_NEED_PART_SCAN consumers (blkdev_get_whole(),
sd_need_revalidate()) should not be affected as the flag
is set internally by disk_scan_partitions().
The retry-on-next-open intention from commit e5cfefa97b
("block: fix scan partition for exclusively open device again")
should also not be affected as the early return paths in
disk_scan_partitions() should be unreachable at device registration
time (bd_holder is NULL and open_partitions is zero).
Fixes: e5cfefa97b ("block: fix scan partition for exclusively open device again")

recv_dless_read() receives a P_DATA_REPLY from a peer into the bio of an
outstanding read request. The peer-supplied payload length reaches it as
the signed int data_size, and two peer-controlled inputs can make it
negative. With a negotiated data-integrity-alg the digest length is
subtracted first, so a reply whose payload is smaller than the digest
underflows data_size. With no integrity algorithm (the default) data_size
is assigned from the unsigned h95/h100 wire length and drbdd() never
bounds it for a payload-carrying command, so a length above INT_MAX casts
it negative; this path needs no non-default feature. The bio receive loop
then computes expect = min_t(int, data_size, bv_len), which is negative,
and drbd_recv_all_warn(mapped, expect) receives with a size_t of SIZE_MAX
into the first mapped page.
The sibling receive path read_in_block() is not affected: it uses an
unsigned size and rejects it against DRBD_MAX_BIO_SIZE before receiving.
Reject a data reply whose size is negative after the optional digest
subtraction, covering both triggers.
Impact: a malicious or man-in-the-middle DRBD peer copies attacker-chosen
bytes past a bio page in the receiver, corrupting kernel memory. A node
that reads from its peer (a diskless node, or read-balancing to the peer)
is exposed in the default configuration; data-integrity-alg is not
required.

We've had an unknown Turing issue for a while with page faults since
large pages and compression.
I've got a patch series that syncs all our L2 handling with ogkm and it
made this fault happen more.
After writing a bunch of debugging patches, I spotted an invalid LPT
entry where there should have been a valid one.
A 64K MAP succeeds on a range, but a subsequent SPT put drops SPT refs
across multiple ranges,
We shouldn't assume all ranges where SPTEs go away will have the same
sparse/invalid/valid state, just iterate over each instead and do the
right thing.

Do not call SMBQueryInformation() command for path with SMB wildcard
characters on non-UNICODE connection because server expands wildcards.
Function cifs_is_path_accessible() needs to check if the real path exists
and must not expand wildcard characters.
Do not dynamically allocate memory for small FILE_ALL_INFO structure and
instead allocate it on the stack. This structure is allocated on stack by
all other functions.
When CAP_NT_SMBS was not negotiated then do not issue CIFSSMBQPathInfo()
command. This command returns failure by non-NT Win9x SMB servers, so there
is no need try it. The purpose of cifs_is_path_accessible() function is
just to check if the path is accessible, so SMBQueryInformation() for old
servers is enough.

When a block request is too large for a single ring entry and the
backend does not support indirect descriptors, blkfront splits it across
two ring requests. This only happens when the frontend runs on a
64K-page kernel (e.g. arm64): there, even a single-page request may not
fit in one ring slot and must be split. blkif_ring_get_request() is
called twice and both shadow slots (shadow[id] and shadow[extra_id])
point at the *same* struct request, linked through associated_id.
blkif_completion() collapses the pair on the normal completion path,
recycling the second slot and completing the request once. The
suspend/resume walk in blkfront_resume() does not: it visits every
shadow slot with ->request set and calls blk_mq_end_request() or
re-queues ->request. For an in-flight split request it therefore
processes the shared struct request twice on resume/migration -- a
double completion.
Skip the secondary slot of a split request in the resume walk so each
logical request is processed exactly once. The secondary slot is the
linked one (associated_id != NO_ASSOCIATED_ID) that carries no
scatter-gather list (num_sg == 0); the first slot always keeps the sg
list. The bug is only reachable on suspend/resume or live migration of
such a guest, so it has no local reproducer.

This reverts commit ed64f5c546.
Since commit:
648790e095 ("io_uring: restore RCU read section in io_req_local_work_add()")
io_ctx_mark_taskrun() is only ever called with the RCU read lock
already held, like previously. Hence's there's no need for this commit
anymore, which grabbed the RCU read lock inside io_ctx_mark_taskrun().
Signed-off-by: Jens Axboe <axboe@kernel.dk>
The task-work refactor that moved io_req_local_work_add() out of
io_uring.c into the new io_uring/tw.c dropped the whole-body
guard(rcu)() that used to cover the function body.
For DEFER_TASKRUN rings the ring teardown still relies on that RCU read
section pairing with its grace period:
/* pairs with RCU read section in io_req_local_work_add() */
if (ctx->flags & IORING_SETUP_DEFER_TASKRUN)
synchronize_rcu();
io_ring_ctx_free(ctx);
io_req_local_work_add() keeps dereferencing ctx after mpscq_push() has
published the request to the work list (ctx->cq_wait_nr, and
ctx->submitter_task in the final wake_up_state()), without holding a ctx
reference across that window. The RCU read section was the only thing
guaranteeing an in-flight adder had finished touching ctx before
io_ring_ctx_free() ran; synchronize_rcu() only waits for readers that
are actually inside an RCU read-side critical section. With the guard
gone the grace period no longer pairs with anything on the add side, so
ctx can be freed and reused while io_req_local_work_add() is still using
it.

The try_harder contiguous fallback could return a range whose start
offset did not match the caller's min_block_size. When a candidate's
start is misaligned, realign it: free the misaligned run and reallocate
exactly @size at the next lower min_block_size boundary. This keeps the
returned size unchanged with no surplus to trim, and rejects the request
only when no aligned candidate fits.
v2: align misaligned candidates down to min_block_size instead of
bailing out, for both the RHS and LHS paths (Matthew).

smb2_ioctl_query_info() validates the PASSTHRU_FSCTL response payload
before copying it to userspace.
The payload offset and length both come from 32-bit fields. The bounds
check currently adds OutputOffset and qi.input_buffer_length directly, so
the addition can wrap in 32-bit arithmetic before the result is compared
against the response buffer length.
A malicious server can use a large OutputOffset and a small OutputCount
to make the wrapped sum pass the bounds check. The later copy_to_user()
then reads from io_rsp + OutputOffset, outside the response buffer.
Use size_add() for the offset plus length check so overflow is treated as
out of bounds.

macsec_encrypt() reads the Ethernet header via eth_hdr(skb)
(skb->head + skb->mac_header) to memmove() the 12 source/destination MAC
bytes forward and make room for the SecTAG.
On the AF_PACKET SOCK_RAW + PACKET_QDISC_BYPASS transmit path the skb
reaches the macsec ndo_start_xmit() with the MAC header unset, so
eth_hdr(skb) resolves to skb->head + (u16)~0 and the read is out of
bounds: a 12-byte heap over-read that is also emitted on the wire as the
frame's outer source/destination MAC. KASAN reports a slab-out-of-bounds
read in macsec_start_xmit() on 6.0; on current mainline a CONFIG_DEBUG_NET
build flags it as an unset mac header in skb_mac_header().
On the TX path the L2 header is at skb->data, so use skb_eth_hdr(), added
by commit 96cc4b6958 ("macvlan: do not assume mac_header is set in

The loopback move_data() performs a memcpy into the registered DMB
without checking whether offset + size exceeds the DMB length. Unlike
real ISM hardware, which enforces memory region bounds natively, the
software loopback has no such protection.
A peer-supplied out-of-bounds offset or oversized write would result in
an OOB write past the allocated kernel buffer. Add an explicit bounds
check before the memcpy to reject such requests with -EINVAL.

Before arming a user job, xe_exec_ioctl() only added the VM's
dma-resv KERNEL slot as a dependency. That slot covers rebinds and
the kernel operations of the VM's private BOs, but not external BOs
(bo->vm == NULL), which carry their kernel operations (evictions,
moves, ...) in their own dma-resv KERNEL slot.
The DMA_RESV_USAGE_KERNEL slot is the cross-driver contract for
memory management operations that must complete before the BO or its
backing store may be used: any accessor is required to wait on the
KERNEL fences before touching the resv. By skipping the external BOs'
KERNEL slots, the exec path violated that contract and could schedule
a user job while a kernel operation on an external BO mapped by the VM
was still in flight, racing against it and potentially reading or
writing memory that was being moved.
Replace the VM-only dependency with an iteration over every object
locked by the exec, adding each object's KERNEL slot as a job
dependency. This covers the VM resv (rebinds and private BOs) as well
as every external BO, mirroring the drm_gpuvm_resv_add_fence() call
that later publishes the job fence to the same set of objects.
Long-running mode continues to skip this, as before.

xe_vm_populate_pgtable() indexed the source PTE array (update->pt_entries)
by the per-call loop counter, assuming each call starts at the first entry
of the update. That holds for the CPU bind path
(xe_migrate_update_pgtables_cpu), which populates a whole update in a single
call, but not for the GPU bind path: write_pgtable() splits an update into
MAX_PTE_PER_SDI (510) sized MI_STORE_DATA_IMM chunks, invoking the populate
callback once per chunk with an advancing qword_ofs but a fresh command-
buffer destination pointer.
As a result, every chunk after the first re-read pt_entries from index 0
instead of from its true offset, so PTEs beyond the first 510 entries of a
single update were programmed with the wrong physical pages, shifting the
mapping by exactly MAX_PTE_PER_SDI pages.
This stayed latent because a single update only exceeds 510 qwords when a
large (e.g. 2M) region is bound as individual 4K PTEs rather than a single
huge-page entry, which happens when the backing store is sufficiently
fragmented. It was surfaced by the BO defrag path, which deliberately
rebinds such fragmented ranges via the GPU bind path, producing
deterministic data corruption offset by 510 pages.
Index pt_entries by the chunk's absolute offset relative to update->ofs so
both the CPU and GPU paths pick the correct entries.

Mbox handling of nix_set_rx_mode for a VF with promiscuous and
all_multi flags set to false causes deletion of the PF's promiscuous

Guard both rvu_npc_enable_allmulti_entry() and

that a VF bringing up or tearing down its interface cannot inadvertently
clear the PF's MCAM rules.

====================
netfilter: updates for net
The following patchset contains Netfilter fixes for *net*.
Most of these are LLM fixes for old issues flagged by sashiko/LLMs.
Many of these trigger drive-by-findings in sashiko. In particular:
- many load/store tearing and missing memory barriers, races
etc. in ipset, esp. with GC and resizing.
Keeping the proposed patches spinning for yet-another-iteration
keeps legit fixes back, so I prefer to add these now and follow
up with other reports later.
- flowtable work queue still has possible races with teardown,
but same rationale as with ipset: drive-by findings, not
problems coming with the flowtable IPIP changeset in this PR.
- ever since unreadable frag skb support was added in 6.12, we can no
longer do: BUG_ON(skb_copy_bits( ...): it will fire with such skbs.
Mina Almasry is looking at similar patterns elsewhere in the stack.
1) Guard skb->mac_header adjustment after IPv6 defragmentation in
nf_conntrack_reasm. From Xiang Mei.
2) NUL-terminate ebtables table names before calling find_table_lock() to
prevent stack-out-of-bounds reads. Also from Xiang Mei.
3) Zero the ebtables chainstack array, else error unwind may free bogus
pointer when CPU mask is sparse. All three issues date from 2.6 days.
4) Ensure ebtables module names are c-strings, same bug pattern as 2).
Bug added in 4.6.
5) Fix catchall element handling for inverted lookups in nft_lookup. Fold the
catchall lookup into ext before computing the match status. Was like
this ever since catchall elements got introduced in 5.13.
From Tamaki Yanagawa.
6-9) ipset updates from Jozsef Kadlecsik:
- mark rcu protected areas correctly
- address gc and resize clash in the comment extension
- add/del backlog cleanup in the error path
- allocate right size for the generic hash structure
10-12): IPIP flowtable updates from Pablo Neira Ayuso:
- Use the current direction's route when pushing IPIP headers
Fix incorrect headroom and fragmentation offset calculations.
- Avoid hardware offload for IPIP tunnels due to lack of driver support.
- Support IPIP tunnels with direct xmit in netfilter flowtable.
dst_cache and dst_cookie are moved outside the union to share route
state across flows. This is a followup to work done in 6.19 cycle.
13) Don't BUG() on skb_copy_bits error. Handle unreadable fragments by
either returning an error or restricting the copy operations to linear area,
This became an issue when unreable frag support was merged in 6.12.
14-16): IPVS updates from Yizhou Zhao:
- Pass parsed transport offset to IPVS state handlers.
update callback signatures.
- use correct transport header offset on state lookp in TCP.
As-is it was possible for ipv6 extension header data to be
treated as L4 header.
- same for SCTP. This was also broken since 2.6 days.
17) Ensure inner IP headers in ICMP errors are in the skb headroom after
stripping outer headers. Add more checks for the length of inner headers.
This was broken since 3.7 days.
From Julian Anastasov.

ETHTOOL_A_RSS_HFUNC and ETHTOOL_A_RSS_INPUT_XFRM are NLA_U32 attributes,
but ethnl_rss_set() and ethnl_rss_create_doit() parse them with
ethnl_update_u8(), which reads a single byte.
On little endian this happens to read the least significant byte and
works as long as the value fits in a byte. On big endian it reads the
most significant byte, so the requested value is parsed incorrectly.
The destination fields in struct ethtool_rxfh_param are u8, so the
attribute can't be read directly with ethnl_update_u32().
Cap the hfunc policy at U8_MAX so an out of range value is rejected
instead of being silently truncated into the u8 field, and add
ethnl_update_u8_u32() to read the full u32 and narrow it into the u8
destination.

Fixes: d3e2c7bab1 ("ethtool: rss: support setting input-xfrm via Netlink")

mlx5_tun_entropy_refcount_inc() counts both VXLAN and L2-to-L3
tunnel reformat entries as entropy-enabling users. The matching
decrement path only handled VXLAN, leaving L2-to-L3 tunnel entries
counted after release.
Handle MLX5_REFORMAT_TYPE_L2_TO_L3_TUNNEL in
mlx5_tun_entropy_refcount_dec() as well so the enabling entry
refcount remains balanced.
