WARNING: fs/nilfs2/btree.c:2302 at nilfs_btree_assign+0x983/0xbe0 fs/nilfs2/btree.c:2302,
Analysis found that a corrupted file has the following btree layout:

The test truncated the file to 2 bytes, which partially zeroes the first
block and adds the file to the dirty list. When the segment constructor
writes it and assigns a new blocknr for the index block, it searches the
btree with key=0 and min level=2, and apparently returns -ENOENT.
Therefore, we should perform more checks on the btree nodes and return
early.

tcf_action_check_ctrlact() range checks the primary control action:
if (!opcode)
ret = action > TC_ACT_VALUE_MAX ? -EINVAL : 0;
TC_ACT_VALUE_MAX is TC_ACT_TRAP, so kernel-internal verdicts above it
cannot be set that way. But act_gact and act_police each carry a second,
independent control action supplied by user space that never reaches that
helper - TCA_GACT_PROB.paction and TCA_POLICE_RESULT. Both only reject
TC_ACT_GOTO_CHAIN, so any other value is stored verbatim and returned
verbatim from the action.
In particular user space can store TC_ACT_CONSUMED, which is
TC_ACT_VALUE_MAX + 1 and is deliberately not part of the UAPI value
range. That verdict tells every caller the action took ownership of the
skb, so nobody frees it: sch_handle_ingress(), sch_handle_egress() and
tcf_qevent_handle() all deliberately skip the free for it. The result is
one leaked sk_buff plus its data buffer per packet traversing the filter,
unbounded, for all traffic on the chain including kernel-generated
packets.
Both are trivially deterministic. act_gact clamps tcfg_pval to >= 1, so
with pval = 1 gact_determ() returns the fallback for every packet.
act_police has no mandatory rate, so rate = 0 leaves tcfp_mtu = ~0 and
tcf_police_mtu_check() always passes.
TC_ACT_CONSUMED was added by commit 720f22fed8 ("net: sched: refactor
reinsert action"), after both goto-chain guards were written:
commit 9469f375ab ("net/sched: act_gact: disallow 'goto chain' on
fallback control action") and
commit c08f5ed5d6 ("net/sched: act_police: disallow 'goto chain' on
fallback control action"). Neither guard was widened when the new
verdict appeared.
Factor the existing range test out of tcf_action_check_ctrlact() as
tcf_action_valid() and apply it to both fallbacks. The helper cannot call
tcf_action_check_ctrlact() directly because that also allocates a
goto_chain, which is exactly what these two sites must not do.
Reproduced on v7.2-rc6: kmemleak reports one leaked 232-byte
skbuff_head_cache object plus its 704-byte data buffer per packet. With
this patch both configurations are rejected with -EINVAL and kmemleak
reports none.

veth_poll() derives the index of the peer TX queue to wake from
rq->xdp_rxq.queue_index. That field is only initialized by
xdp_rxq_info_reg() in veth_enable_xdp_range(), which runs only when an
XDP program is attached. On the plain GRO/NAPI path
(veth_napi_enable_range()) xdp_rxq_info_reg() is never called, so
queue_index stays 0 for every queue, as priv->rq is zero-allocated.
So in a multi-queue setup with GRO enabled and no XDP program attached,
every NAPI instance looks at the peer's TX queue 0. If veth_xmit() stops
peer TX queue 1 because the ptr_ring is full (NETDEV_TX_BUSY), nothing
ever wakes it again: the poller draining queue 1 wakes queue 0 instead.
veth implements no ndo_tx_timeout, so the netdev watchdog does not kick
in either, and the queue stays stopped indefinitely.
Derive the index from the position of the rq within priv->rq instead,
which is correct regardless of whether XDP was ever enabled.

netdev_queue_get_dma_dev() uses "compat" locking assert which wants
either the rtnl_lock or netdev instance lock. This is not right,
the callers are taking the instance lock unconditionally. All entry
points for queue config are purely instance locked.
In other words the callers use netdev_get_by_index_lock(), not
netdev_get_by_index_lock_ops_compat(). All the state we will
access is effectively instance lock protected (it's const for
devices which are not ops-locked).
Update the assert to avoid false positive warnings.

uses a threshold of 100000 us (100 ms), not 1000000 us (1 s).
The lower threshold causes false positives on slower hardware where
normal connection latency occasionally exceeds 100 ms but never
approaches the 1 s spike that indicates the actual FIN/ACK race bug.

====================
eth: bnxt: fix IRQ notifier bugs
I was trying to make bnxt preserve IRQ mappings across reconfiguration.
While hacking on that I noticed 2 bugs in the notifiers that should
probably be fixed before development work.
First one is simple - TPH recofig makes aARFs not work. There can only
be one notifier per IRQ and TPH "steals" the callback from the rmap
updates. Fix by patches 1 and 2.
Second one is a deadlock between the affinity notifier and reconfig.
This one is a bit more involved (patch 3 and 4).
Unfortunately, I can't really verify the problem or test the fix.
I managed to get my hands on a system with an AMD Venice CPU which
is supposed to support TPH, but the ACPI is missing some bits to
actually advertise it. pcie_tph_get_cpu_st() returns -EINVAL.

Unregistering IRQ affinity notifiers waits for the callback synchronously.
bnxt takes the netdev instance lock in the notifier (to restart the queue)
and cancels the work under the same lock. This may obviously deadlock.
Move the restart to the async service task. The queue restart isn't
super time sensitive. Store the new TPH tag, schedule the task.
Safely canceling the service task is already ironed out.
In bnxt_request_irq() the order of registering notifier, affinity and
initial TPH programming has to be inverted. I think it was racy
previously since user may trigger an update as soon as notifier
is installed.
There's a small known gap - if pcie_tph_get_cpu_st() fails at init
and the target tag is 0 we may miss programming the entry.
This does not seem worth fixing, the code has skip-on-failure
all over the place, anyway.

The TPH support must have broken aRFS in bnxt. IRQ can only have one
notifier, so installing the TPH notifier is overriding the one implicitly
installed by irq_cpu_rmap_add().
Make sure we call cpu_rmap_update() from the TPH notifier.
We need to be careful with the ordering and not free the rmap
until we unregistered the notifier. Note that moving the rmap
freeing after the early return in bnxt_free_irq() is fine -
there's no path that could leave rmap with irq_tbl being NULL.

Add pinctrl support for the Rockchip RV1106, based on the vendor
kernel in the Luckfox Pico SDK [1] at commit 824b817f8 (a Linux
5.10.160 kernel tree). Each GPIO bank has its own IO control (IOC)
register block, referenced by the rockchip,grf phandle of the bank
node; the register offsets are relative to the bank's own block. The
drive strength uses the RK3568-style exponential encoding and only
pins 0-6 of GPIO0 have drive-strength registers.
The RV1103 is a package variant of the RV1106 with fewer pins and uses
the same pin controller.

The decoding of the 2-bit and 8-bit level drive-strength values sits in
rockchip_set_drive_perpin(), where it is unreachable: the SoCs whose
banks declare these drive types (RK3506 and RV1103B) take the early
ctrl->type branch in the set path, and the read-and-decode logic in a
set function has no purpose. Meanwhile rockchip_get_drive_perpin()
lacks the decoding, so pin_config_get() and the debugfs output report
-EINVAL for these SoCs.
Move the two cases to rockchip_get_drive_perpin(), where they belong.

exit.c does not check the return value of exit__open(). If it returns
NULL, which happens when the skeleton wrapper fails to allocate the
object or open the BPF ELF, the very next line dereferences it via
SCX_ENUM_INIT(). That macro expands to SCX_ENUM_SET(), which accesses
skel->rodata, causing a NULL pointer dereference.
Every other selftest guards this with SCX_FAIL_IF(!skel, ...); exit.c
is the only one missing it.

The introductory paragraph for the IO controller still states that
weight based distribution is "available only if cfq-iosched is in use"
and that "neither scheme is available for blk-mq devices". This text
dates from when the cgroup v2 documentation was first written (2015)
and was correct at the time, but is no longer accurate:
* cfq-iosched was removed in v5.0;
* blk-mq is now the only block I/O path, and both the absolute limit
scheme (io.max via blk-throttle) and the weight based scheme
(io.weight via iocost, or io.bfq.weight under BFQ) work on it;
* latency based protection (iolatency) and I/O priority (ioprio)
controllers have since been added.
The rest of the section already documents io.weight, io.max,
io.cost.{qos,model}, io.latency and io.prio.class correctly, so the
introduction is the only part that contradicts them. Rewrite it to
reflect the current state.

The cpuset selftests use awk -e to parse cgroup mount points. This
works with gawk, but mawk rejects the option. In test_cpuset_prs.sh,
this leaves CGROUP2 empty and causes the test to skip as if cgroup v2
were not mounted. The same non-portable invocation exists in the cpuset
v1 hotplug test.
The scripts only need to pass a single awk program. Use the standard awk
invocation without -e so mount point detection works with awk
implementations that do not support the gawk extension.

The per-NUMA-node descriptor DMA pools are created lazily from
nvme_init_hctx_common() once the admin tag set is allocated, but they are
only destroyed in nvme_remove() via nvme_release_descriptor_pools(). Any
probe failure after the admin tag set has been allocated unwinds through
the out_disable label and nvme_pci_free_ctrl(), neither of which releases
the pools, leaking the dma_pool objects.
Release the descriptor pools in the out_disable error path. It must not
be added to nvme_pci_free_ctrl(), as that would double-free against
nvme_remove() on the normal teardown path.

When a host issues an Identify command with CNS 07h (Active Namespace ID
List for a specific I/O Command Set), nvmet_execute_identify_nslist() is
called with match_css set. The command-set filter dereferences req->ns,
but this handler never calls nvmet_req_find_ns(), so req->ns is always
NULL (nvmet_req_init() resets it to NULL). As soon as an enabled
namespace with an NSID greater than the requested value exists,
req->ns->csi dereferences a NULL pointer and oopses.
Besides the crash, the comparison is logically wrong: to filter the list
by command set it must test the command set of the namespace being
iterated, not a single fixed value. Use the loop variable ns->csi.

Add a VFIO selftest driver for the Intel Gigabit Ethernet controller
(IGB), specifically targeting the 82576 device. IGB is fully virtualized
in QEMU which makes it easy to run VFIO selftests without needing any
specific hardware.
Since IGB is an Ethernet device, it cannot support DMA transfers smaller
than the minimum Ethernet payload size (60 bytes) without hardware padding
corrupting adjacent memory. The driver asserts that the transfer size is
at least 60 bytes to prevent this.
All VFIO selftest drivers must implement DMA/memcpy operations, but IGB
doesn't have a native memcpy feature, so the loopback feature (described
in section 3.5.6.3 of IGB specification) is used to implement it. To
support testing on both QEMU and physical hardware, the driver uses PHY
internal loopback with some QEMU-specific fallbacks. The driver also
supports MSI-X routing and interrupt management, and disables PCIe
completion timeout retries to ensure clean recovery during invalid-DMA
tests.
Users can verify the driver works in QEMU by building the kernel,
building VFIO selftests, and then running the vfio_pci_driver_test using
this command:
vng \
--run arch/x86/boot/bzImage \
--user root \
--disable-microvm \
--memory 32G \
--cpus 8 \
--qemu-opts="-M q35,accel=kvm,kernel-irqchip=split" \

Selftest drivers that recover from a fault by issuing VFIO_DEVICE_RESET
need to re-arm device interrupts afterwards. VFIO_DEVICE_RESET tears
down the kernel-side IRQ trigger so a subsequent VFIO_DEVICE_SET_IRQS
is required, but the user-side eventfds (and any fd cached in a test
fixture) are still valid and must be preserved.
vfio_pci_irq_enable() refuses to be called for vectors that already
have an eventfd (VFIO_ASSERT_LT), and vfio_pci_irq_disable() closes
all eventfds before resetting the trigger, so neither is suitable.
Add vfio_pci_irq_reenable(device, index, vector, count) which asserts
that the requested range has existing eventfds and re-issues
VFIO_DEVICE_SET_IRQS using them. Signature mirrors vfio_pci_irq_enable().
Add vfio_pci_msi{,x}_reenable() wrappers around vfio_pci_irq_reenable()
for additional ease of use and readability.

nvme_setup_discard() always maps sizeof(struct nvme_dsm_range) *
NVME_DSM_MAX_RANGES = 4096 bytes as the DSM payload however many ranges
the command declares, because some devices ignore the 'Number of Ranges'
field - the Fixes: commit records two that read past the declared ranges.
A single-range discard fills only the first 16 bytes.
Normally the buffer comes from kzalloc() and the other 4080 bytes are
zero. When that allocation fails the code falls back to the
per-controller ctrl->discard_page, which nvme_init_ctrl() obtains with
alloc_page(GFP_KERNEL) and nothing ever zeroes, so those 4080 bytes are
whatever the page last held and are handed to the controller. Reaching
it requires the kzalloc(GFP_ATOMIC | __GFP_NOWARN) to fail, that is
memory pressure; it is not remotely triggerable. Failing the allocation
under KMSAN reproduces it, with the leaked tail full of vmemmap struct
page pointers. The extent in the report is a partial transfer of the
payload, not the whole 4096 bytes; the 16-byte boundary in it is the one
declared range:

descriptor list populated from the underlying passthru controller's
Identify response, which is device reported. The loop advanced pos by
device controlled amounts (sizeof(*cur) + nidl) without checking that
the next descriptor header actually fits inside the buffer, so a
malicious device could push pos to within a few bytes of the buffer end
and cause cur->nidl, cur->nidt or the reserved field to be read past the
allocation.
Additionally, when a CSI descriptor lands exactly at the last valid
header offset, cur + 1 points one byte past the end of the buffer.
The unconditional memcpy(&csi, cur + 1, NVME_NIDT_CSI_LEN) could read
that out-of-bounds byte and copy it back to the initiator via
nvmet_copy_to_sgl(), leaking adjacent heap memory.
