selftests/net: Add additional test coverage in nk_qlease
Add further netkit queue-lease coverage for netns lifecycle of the guest and physical halves, channel resize across active leases, single-device and multi-lessee scenarios, L3 mode operation, lease capacity exhaustion, and corner-cases of e.g. queue-create rejection paths. Also make the tests more robust by removing the time.sleep(0.1) after netns deletion and turn them into a wait loop.

tools/ynl: Make YnlFamily closeable as a context manager
YnlFamily opens an AF_NETLINK socket in __init__ but has no way to release it other than leaving it to the GC. YnlFamily holds a self reference cycle through SpecFamily's self.family = self in its super().__init__() call, so refcount GC cannot reclaim it and the socket stays open until the cyclic GC runs. If a test creates a guest netns, instantiates a YnlFamily inside it via NetNSEnter(), performs some test case work via Ynl, and then deletes the netns, then the 'ip netns del' only drops the mount binding and cleanup_net in the kernel never runs, so any subsequent test case assertions that objects got cleaned up would fail given this only gets triggered later via cyclic GC run. Add an explicit close() that closes the netlink socket and wire up the __enter__/__exit__ so callers can scope the instance deterministically via 'with YnlFamily(...) as ynl: ...'.

ALSA: control: Validate buf_len before strnlen() in snd_ctl_elem_init_enum_names()
snd_ctl_elem_init_enum_names() advances pointer p through the names
buffer while decrementing buf_len. If buf_len reaches zero but items
remain, the next iteration calls strnlen(p, 0).
While strnlen(p, 0) returns 0 and would hit the existing name_len == 0
error path, CONFIG_FORTIFY_SOURCE's fortified strnlen() first checks
maxlen against __builtin_dynamic_object_size(). When Clang loses track
of p's object size inside the loop, this triggers a BRK exception panic
before the return value is examined.
Add a buf_len == 0 guard at the loop entry to prevent calling fortified
strnlen() on an exhausted buffer.

net: airoha: Add missing PPE configurations in airoha_ppe_hw_init()
Add the following PPE configuration in airoha_ppe_hw_init routine:
- 6RD hw offloading is currently not supported by Netfilter flowtable.
Disable explicitly PPE 6RD offloading in order to prevent PPE to learn
6RD flows and eventually interrupt the traffic.
- Add missing PPE bind rate configuration for L3 and L2 traffic.
PPE bind rate configuration specifies the pps threshold to move a PPE
entry state from UNBIND to BIND. Without this configuration this value
is random.
- Set ageing thresholds to the values used in the vendor SDK in order to
improve connection stability under load and avoid packet loss caused by
fast aging.

net: caif: clear client service pointer on teardown
`caif_connect()` can tear down an existing client after remote shutdown by
calling `caif_disconnect_client()` followed by `caif_free_client()`.
`caif_free_client()` releases the service layer referenced by
`adap_layer->dn`, but leaves that pointer stale.
When the socket is later destroyed, `caif_sock_destructor()` calls
`caif_free_client()` again and dereferences the freed service pointer.
Clear the client/service links before releasing the service object so
repeated teardown becomes harmless.

net: strparser: fix skb_head leak in strp_abort_strp()
When the stream parser is aborted, for example after a message assembly timeout,
it can still hold a reference to a partially assembled message in
strp->skb_head.
That skb is not released in strp_abort_strp(), which leaks the partially
assembled message and can be triggered repeatedly to exhaust memory.
Fix this by freeing strp->skb_head and resetting the parser state in the
abort path. Leave strp_stop() unchanged so final cleanup still happens in
strp_done() after the work and timer have been synchronized.

ALSA: usb-audio: Fix missing error handling for get_min_max*()
The recent fix to add the error return value check from get_min_max*()
missed one case in build_audio_procunit() where no error value is set.
This may lead to an uninitialized variable and confuse the caller
(although this wouldn't happen practically because err is set for the
loop of num_ins at the beginning of the funciton).
Fix it by setting "err = 0" properly at the missing case, too.

tracepoint: balance regfunc() on func_add() failure in tracepoint_add_func()
When a tracepoint goes through the 0 -> 1 transition, tracepoint_add_func()
invokes the subsystem's ext->regfunc() before attempting to install the
new probe via func_add(). If func_add() then fails (for example, when
allocate_probes() cannot allocate a new probe array under memory pressure
and returns -ENOMEM), the function returns the error without calling the
matching ext->unregfunc(), leaving the side effects of regfunc() behind
with no installed probe to justify them.
For syscall tracepoints this is particularly unpleasant: syscall_regfunc()
bumps sys_tracepoint_refcount and sets SYSCALL_TRACEPOINT on every task.
After a leaked failure, the refcount is stuck at a non-zero value with no
consumer, and every task continues paying the syscall trace entry/exit
overhead until reboot. Other subsystems providing regfunc()/unregfunc()
pairs exhibit similarly scoped persistent state.
Mirror the existing 1 -> 0 cleanup and call ext->unregfunc() in the
func_add() error path, gated on the same condition used there so the
unwind is symmetric with the registration.

tracing: Rebuild full_name on each hist_field_name() call
hist_field_name() uses a static MAX_FILTER_STR_VAL buffer for fully
qualified variable-reference names, but it currently appends into that
buffer with strcat() without rebuilding it first. As a result, repeated
calls append a new "system.event.field" name onto the previous one,
which can eventually run past the end of full_name.
Build the name with snprintf() on each call and return NULL if the fully
qualified name does not fit in MAX_FILTER_STR_VAL.

Merge branch 'net-bpf-fix-null-ptr-deref-in-xdp_master_redirect-for-bonding-and-add-selftest'
Jiayuan Chen says: ==================== net,bpf: fix null-ptr-deref in xdp_master_redirect() for bonding and add selftest From: Jiayuan Chen <jiayuan.chen@shopee.com> This series has gone through several rounds of discussion and the maintainers hold different views on where the fix should live (in the generic xdp_master_redirect() path vs. inside bonding). I respect all of the suggestions, but I would like to get the crash fixed first, so this version takes the approach of checking whether the master device is up in xdp_master_redirect(), as suggested by Daniel Borkmann. If a different shape is preferred later it can be done as a follow-up, but the null-ptr-deref should not linger. syzkaller reported a kernel panic, full decoded trace here: https://syzkaller.appspot.com/bug?extid=80e046b8da2820b6ba73 Problem Description bond_rr_gen_slave_id() dereferences bond->rr_tx_counter without a NULL check. rr_tx_counter is a per-CPU counter that bonding only allocates in bond_open() when the mode is round-robin. If the bond device was never brought up, rr_tx_counter stays NULL. The XDP redirect path can still reach that code on a bond that was never opened: bpf_master_redirect_enabled_key is a global static key, so as soon as any bond device has native XDP attached, the XDP_TX -> xdp_master_redirect() interception is enabled for every slave system-wide. The path xdp_master_redirect() -> bond_xdp_get_xmit_slave() -> bond_xdp_xmit_roundrobin_slave_get() -> bond_rr_gen_slave_id() then runs against a bond that has no rr_tx_counter and crashes. Solution Patch 1: Fix this in the generic xdp_master_redirect() by skipping master interception when the master device is not running. Returning XDP_TX keeps the original XDP_TX behaviour on the receiving slave, and avoids calling into any master ->ndo_xdp_get_xmit_slave() on a device that has not fully initialized its XDP state. This is not specific to bonding: any current or future master that defers XDP state allocation to ->ndo_open() is protected. Patch 2: Add a selftest that reproduces the above scenario. v6: https://lore.kernel.org/netdev/20260410113726.368111-1-jiayuan.chen@linux.dev/T/#t v5: https://lore.kernel.org/netdev/20260309030659.xxxxx-1-jiayuan.chen@linux.dev/ v4: https://lore.kernel.org/netdev/20260304074301.35482-1-jiayuan.chen@linux.dev/ v3: https://lore.kernel.org/netdev/20260228021918.141002-1-jiayuan.chen@linux.dev/T/#t v2: https://lore.kernel.org/netdev/20260227092254.272603-1-jiayuan.chen@linux.dev/T/#t v1: https://lore.kernel.org/netdev/20260224112545.37888-1-jiayuan.chen@linux.dev/T/#t [1] https://syzkaller.appspot.com/bug?extid=80e046b8da2820b6ba73 ==================== Link: https://patch.msgid.link/20260411005524.201200-1-jiayuan.chen@linux.dev Signed-off-by: Paolo Abeni <pabeni@redhat.com> |

selftests/bpf: add test for xdp_master_redirect with bond not up
Add a selftest that reproduces the null-ptr-deref in bond_rr_gen_slave_id() when XDP redirect targets a bond device in round-robin mode that was never brought up. The test verifies the fix by ensuring no crash occurs. Test setup: - bond0: active-backup mode, UP, with native XDP (enables bpf_master_redirect_enabled_key globally) - bond1: round-robin mode, never UP - veth1: slave of bond1, with generic XDP (XDP_TX) - BPF_PROG_TEST_RUN with live frames triggers the redirect path Signed-off-by: Jiayuan Chen <jiayuan.chen@linux.dev> Link: https://patch.msgid.link/20260411005524.201200-3-jiayuan.chen@linux.dev Signed-off-by: Paolo Abeni <pabeni@redhat.com> |

net, bpf: fix null-ptr-deref in xdp_master_redirect() for down master
syzkaller reported a kernel panic in bond_rr_gen_slave_id() reached via
xdp_master_redirect(). Full decoded trace:
https://syzkaller.appspot.com/bug?extid=80e046b8da2820b6ba73
bond_rr_gen_slave_id() dereferences bond->rr_tx_counter, a per-CPU
counter that bonding only allocates in bond_open() when the mode is
round-robin. If the bond device was never brought up, rr_tx_counter
stays NULL.
The XDP redirect path can still reach that code on a bond that was
never opened: bpf_master_redirect_enabled_key is a global static key,
so as soon as any bond device has native XDP attached, the
XDP_TX -> xdp_master_redirect() interception is enabled for every
slave system-wide. The path xdp_master_redirect() ->
bond_xdp_get_xmit_slave() -> bond_xdp_xmit_roundrobin_slave_get() ->
bond_rr_gen_slave_id() then runs against a bond that has no
rr_tx_counter and crashes.
Fix this in the generic xdp_master_redirect() by refusing to call into
the master's ->ndo_xdp_get_xmit_slave() when the master device is not
up. IFF_UP is only set after ->ndo_open() has successfully returned,
so this reliably excludes masters whose XDP state has not been fully
initialized. Drop the frame with XDP_ABORTED so the exception is
visible via trace_xdp_exception() rather than silently falling through.
This is not specific to bonding: any current or future master that
defers XDP state allocation to ->ndo_open() is protected.

mount: always duplicate mount
In the OPEN_TREE_NAMESPACE path vfs_open_tree() resolves a path via filename_lookup() without holding namespace_lock. Between the lookup and create_new_namespace() acquiring namespace_lock via LOCK_MOUNT_EXACT_COPY() another thread can unmount the mount, setting mnt->mnt_ns to NULL. When create_new_namespace() then checks !mnt->mnt_ns it incorrectly takes the swap-and-mntget path that was designed for fsmount()'s detached mounts. This reuses a mount whose mnt_mp_list is in an inconsistent state from the concurrent unmount, causing a general protection fault in __umount_mnt() -> hlist_del_init(&mnt->mnt_mp_list) during namespace teardown. Remove the !mnt->mnt_ns special case entirely. Instead, always duplicate the mount: - For OPEN_TREE_NAMESPACE use __do_loopback() which will properly clone the mount or reject it via may_copy_tree() if it was unmounted in the race window. - For fsmount() use clone_mnt() directly (via the new MOUNT_COPY_NEW flag) since the mount is freshly created by vfs_create_mount() and not in any namespace so __do_loopback()'s IS_MNT_UNBINDABLE, may_copy_tree, and __has_locked_children checks don't apply.

Pull power sequencing updates from Bartosz Golaszewski:
"For this release we have an extension of the pwrseq-pcie-m2 driver
with support for PCIe M.2 Key E connectors.
The rest of the commits fulfill a supporting role: document the
hardware in DT bindings, provide required serdev helpers (this has
been provided in an immutable branch to Rob Herring so you may see it
in his PR as well) and is followed up by some Kconfig fixes from Arnd.
Summary:
- add support for the PCIe M.2 Key E connectors in pwrseq-pcie-m2
- describe PCIe M.2 Mechanical Key E connectors in DT bindings
- add serdev helpers for looking up devices by OF nodes
- minor serdev core rework to enable support for PCIe M.2 Key E
connectors"

gpio updates for v7.1-rc1
GPIO core:
- defer probe on software node lookups when the remote software node
exists but has not been registered as a firmware node yet
- unify GPIO hog handling by moving code duplicated in OF and ACPI
modules into GPIO core and allow setting up hogs with software nodes
- allow matching GPIO controllers by secondary firmware node if matching
by primary does not succeed
- demote deferral warnings to debug level as they are quite normal when
using software nodes which don't support fw_devlink yet
- disable the legacy GPIO character device uAPI v1 supprt in Kconfig by
default
- rework several core functions in preparation for the upcoming Revocable
helper library for protecting resources against sudden removal, this
reduces the number of SRCU dereferences in GPIO core
- simplify file descriptor logic in GPIO character device code by using
FD_PREPARE()
- introduce a header defining symbols used by both GPIO consumers and
providers to avoid having to include provider-specific headers from
drivers which only consume GPIOs
- replace snprintf() with strscpy() where formatting is not required
New drivers:
- add the gpio-by-pinctrl generic driver using the ARM SCMI protocol to
control GPIOs (along with SCMI changes pulled from the pinctrl tree)
- add a driver providing support for handling of platform events via
GPIO-signalled ACPI events (used on Intel Nova Lake and later platforms)
Driver changes:
- extend the gpio-kempld driver with support for more recent models,
interrupts and setting/getting multiple values at once
- improve interrupt handling in gpio-brcmstb
- add support for multi-SoC systems in gpio-tegra186
- make sure we return correct values from the .get() callbacks in several
GPIO drivers by normalizing any values other than 0, 1 or negative error
numbers
- use flexible arrays in several drivers to reduce the number of required
memory allocations
- simplify synchronous waiting for virtual drivers to probe and remove the
dedicated, a bit overengineered helper library dev-sync-probe
- remove unneeded Kconfig dependencies on OF_GPIO in several drivers and
subsystems
- convert the two remaining users of of_get_named_gpio() to using GPIO
descriptors and remove the (no longer used) function along with the
header that declares it
- add missing includes in gpio-mmio
- shrink and simplify code in gpio-max732x by using guard(mutex)
- remove duplicated code handling the 'ngpios' property from gpio-ts4800,
it's already handled in GPIO core
- use correct variable type in gpio-aspeed
- add support for a new model in gpio-realtek-otto
- allow to specify the active-low setting of simulated hogs over the
configfs interface (in addition to existing devicetree support) in
gpio-sim
Bug fixes:
- clear the OF_POPULATED flag on hog nodes in GPIO chip remove path on
OF systems
- fix resource leaks in error path in gpiochip_add_data_with_key()
- drop redundant device reference in gpio-mpsse
Tests:

"For this merge window we have two new drivers: support for
GPIO-signalled ACPI events on Intel platforms and a generic
GPIO-over-pinctrl driver using the ARM SCMI protocol for

Several things have been reworked in GPIO core: we unduplicated GPIO
hog handling, reduced the number of SRCU locks and dereferences,
improved support for software-node-based lookup and removed more
legacy code after converting remaining users to modern alternatives.

Pull power management updates from Rafael Wysocki:
"Once again, cpufreq is the most active development area, mostly
because of the new feature additions and documentation updates in the
amd-pstate driver, but there are also changes in the cpufreq core
related to boost support and other assorted updates elsewhere.
Next up are power capping changes due to the major cleanup of the
Intel RAPL driver.
On the cpuidle front, a new C-states table for Intel Panther Lake is
added to the intel_idle driver, the stopped tick handling in the menu
and teo governors is updated, and there are a couple of cleanups.
Apart from the above, support for Tegra114 is added to devfreq and
there are assorted cleanups of that code, there are also two updates
of the operating performance points (OPP) library, two minor updates
related to hibernation, and cpupower utility man pages updates and
cleanups.

Pull ACPI support updates from Rafael Wysocki:
"These include an update of the CMOS RTC driver and the related ACPI
and x86 code that, among other things, switches it over to using the
platform device interface for device binding on x86 instead of the PNP
device driver interface (which allows the code in question to be
simplified quite a bit), a major update of the ACPI Time and Alarm
Device (TAD) driver adding an RTC class device interface to it, and
updates of core ACPI drivers that remove some unnecessary and not
really useful code from them.
Apart from that, two drivers are converted to using the platform
driver interface for device binding instead of the ACPI driver one,
which is slated for removal, support for the Performance Limited
register is added to the ACPI CPPC library and there are some
janitorial updates of it and the related cpufreq CPPC driver, the ACPI
processor driver is fixed and cleaned up, and NVIDIA vendor CPER
record handler is added to the APEI GHES code.
Also, the interface for obtaining a CPU UID from ACPI is consolidated
across architectures and used for fixing a problem with the PCI TPH
Steering Tag on ARM64, there are two updates related to ACPICA, a
minor ACPI OS Services Layer (OSL) update, and a few assorted updates
related to ACPI tables parsing.
Specifics:

unsigned long and use set_bit() / clear_bit() based accessors
- Document how to check for the property presence
- devres:
- Separate struct devres_node from its "subclasses" (struct devres,
struct devres_group); give struct devres_node its own release and
free callbacks for per-type dispatch

ARCH_DMA_MINALIGN alignment overhead of struct devres
- Export struct devres_node and its init/add/remove/dbginfo
primitives for use by Rust Devres<T>

- Use guard(spinlock_irqsave) where applicable; consolidate unlock
paths in devres_release_group()
- driver_override:
- Convert PCI, WMI, vdpa, s390/cio, s390/ap, and fsl-mc to the
generic driver_override infrastructure, replacing per-bus
driver_override strings, sysfs attributes, and match logic; fixes
a potential UAF from unsynchronized access to driver_override in
bus match() callbacks
- Simplify __device_set_driver_override() logic
- kernfs:
- Send IN_DELETE_SELF and IN_IGNORED inotify events on kernfs
file and directory removal

driver_init(), making it available early in the boot process
- Move kernel_kobj initialization (ksysfs_init) earlier to support
the above

- Constify attribute group array pointers to
'const struct attribute_group *const *' in sysfs functions,
device_add_groups() / device_remove_groups(), and struct class
- Rust:
- Devres:
- Embed struct devres_node directly in Devres<T> instead of going
through devm_add_action(), avoiding the extra allocation and
the unnecessary ARCH_DMA_MINALIGN alignment
- I/O:
- Turn IoCapable from a marker trait into a functional trait
carrying the raw I/O accessor implementation (io_read /
io_write), providing working defaults for the per-type Io
methods
- Add RelaxedMmio wrapper type, making relaxed accessors usable
in code generic over the Io trait
- Remove overloaded per-type Io methods and per-backend macros
from Mmio and PCI ConfigSpace
- I/O (Register):
- Add IoLoc trait and generic read/write/update methods to the Io
trait, making I/O operations parameterizable by typed locations
- Add register! macro for defining hardware register types with
typed bitfield accessors backed by Bounded values; supports
direct, relative, and array register addressing
- Add write_reg() / try_write_reg() and LocatedRegister trait

Example:
```
register! {
/// UART control register.
CTRL(u32) @ 0x18 {
/// Receiver enable.
19:19 rx_enable => bool;
/// Parity configuration.
14:13 parity ?=> Parity;
}
/// FIFO watermark and counter register.
WATER(u32) @ 0x2c {
/// Number of datawords in the receive FIFO.
26:24 rx_count;
/// RX interrupt threshold.
17:16 rx_water;
}
}
impl WATER {
fn rx_above_watermark(&self) -> bool {
self.rx_count() > self.rx_water()
}
}
fn init(bar: &pci::Bar<BAR0_SIZE>) {
let water = WATER::zeroed()
.with_const_rx_water::<1>(); // > 3 would not compile
bar.write_reg(water);
let ctrl = CTRL::zeroed()
.with_parity(Parity::Even)
.with_rx_enable(true);
bar.write_reg(ctrl);
}
fn handle_rx(bar: &pci::Bar<BAR0_SIZE>) {
if bar.read(WATER).rx_above_watermark() {
// drain the FIFO
}
}
fn set_parity(bar: &pci::Bar<BAR0_SIZE>, parity: Parity) {

Crypto library updates for 7.1
- Migrate more hash algorithms from the traditional crypto subsystem
to lib/crypto/.
Like the algorithms migrated earlier (e.g. SHA-*), this simplifies
the implementations, improves performance, enables further
simplifications in calling code, and solves various other issues:
- AES CBC-based MACs (AES-CMAC, AES-XCBC-MAC, and AES-CBC-MAC)
- Support these algorithms in lib/crypto/ using the AES
library and the existing arm64 assembly code
- Reimplement the traditional crypto API's "cmac(aes)",
"xcbc(aes)", and "cbcmac(aes)" on top of the library
- Convert mac80211 to use the AES-CMAC library. Note: several
other subsystems can use it too and will be converted later
- Drop the broken, nonstandard, and likely unused support for
"xcbc(aes)" with key lengths other than 128 bits
- Enable optimizations by default
- GHASH
- Migrate the standalone GHASH code into lib/crypto/
- Integrate the GHASH code more closely with the very similar
POLYVAL code, and improve the generic GHASH implementation
to resist cache-timing attacks and use much less memory
- Reimplement the AES-GCM library and the "gcm" crypto_aead
template on top of the GHASH library. Remove "ghash" from
the crypto_shash API, as it's no longer needed
- Enable optimizations by default
- SM3
- Migrate the kernel's existing SM3 code into lib/crypto/, and
reimplement the traditional crypto API's "sm3" on top of it
- I don't recommend using SM3, but this cleanup is worthwhile
to organize the code the same way as other algorithms
- Testing improvements
- Add a KUnit test suite for each of the new library APIs
- Migrate the existing ChaCha20Poly1305 test to KUnit
- Make the KUnit all_tests.config enable all crypto library tests
- Move the test kconfig options to the Runtime Testing menu
- Other updates to arch-optimized crypto code
- Optimize SHA-256 for Zhaoxin CPUs using the Padlock Hash Engine
- Remove some MD5 implementations that are no longer worth keeping
- Drop big endian and voluntary preemption support from the arm64
code, as those configurations are no longer supported on arm64
- Make jitterentropy and samples/tsm-mr use the crypto library APIs
Note: the overall diffstat is neutral, but when the test code is
excluded it is significantly negative:

Description for this pull request:
- Implement FALLOC_FL_ALLOCATE_RANGE to add support for preallocating
clusters without zeroing, helping to reduce file fragmentation.
- Add a unified block readahead helper for FAT chain conversion, bitmap
allocation, and directory entry lookups.
- Optimize exfat_chain_cont_cluster() by caching buffer heads to minimize
mark_buffer_dirty() and mirroring overhead during NO_FAT_CHAIN to
FAT_CHAIN conversion.
- Switch to truncate_inode_pages_final() in evict_inode() to prevent
BUG_ON caused by shadow entries during reclaim.
- Fix a 32-bit truncation bug in directory entry calculations by ensuring
proper bitwise coercion.
- Fix sb->s_maxbytes calculation to correctly reflect the maximum possible
volume size for a given cluster size, resolving xfstests generic/213.
- Introduced exfat_cluster_walk() helper to traverse FAT chains by
a specified step, handling both ALLOC_NO_FAT_CHAIN and ALLOC_FAT_CHAIN
modes.
- Introduced exfat_chain_advance() helper to advance an exfat_chain
structure, updating both the current cluster and remaining size.
- Remove dead assignments and fix Smatch warnings.

Pull nilfs2 updates from Viacheslav Dubeyko:
"This contains fixes of syzbot reported issues in NILFS2 functionality:
- The DAT inode's btree node cache (i_assoc_inode) is initialized
lazily during btree operations.
However, nilfs_mdt_save_to_shadow_map() assumes i_assoc_inode is
already initialized when copying dirty pages to the shadow map
during GC. If NILFS_IOCTL_CLEAN_SEGMENTS is called immediately
after mount before any btree operation has occurred on the DAT
inode, i_assoc_inode is NULL leading to a general protection fault.
Fix this by calling nilfs_attach_btree_node_cache() on the DAT
inode in nilfs_dat_read() at mount time, ensuring i_assoc_inode is
always initialized before any GC operation can use it (Deepanshu
Kartikey)
- nilfs_ioctl_mark_blocks_dirty() uses bd_oblocknr to detect dead
blocks by comparing it with the current block number bd_blocknr. If
they differ, the block is considered dead and skipped.
A corrupted ioctl request with bd_oblocknr set to 0 causes the
comparison to incorrectly match when the lookup returns -ENOENT and
sets bd_blocknr to 0, bypassing the dead block check and calling
nilfs_bmap_mark() on a non- existent block. This causes
nilfs_btree_do_lookup() to return -ENOENT, triggering the
WARN_ON(ret == -ENOENT).
Fix this by rejecting ioctl requests with bd_oblocknr set to 0 at
the beginning of each iteration (Deepanshu Kartikey)"

Merge tag 'hfs-v7.1-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/vdubeyko/hfs
Pull hfsplus updates from Viacheslav Dubeyko:
"This contains several fixes of syzbot reported issues and HFS+ fixes
of xfstests failures.
- Fix a syzbot reported issue of a KMSAN uninit-value in
hfsplus_strcasecmp().
The root cause was that hfs_brec_read() doesn't validate that the
on-disk record size matches the expected size for the record type
being read. The fix introduced hfsplus_brec_read_cat() wrapper that
validates the record size based on the type field and returns -EIO
if size doesn't match (Deepanshu Kartikey)
- Fix a syzbot reported issue of processing corrupted HFS+ images
where the b-tree allocation bitmap indicates that the header node
(Node 0) is free. Node 0 must always be allocated. Violating this
invariant leads to allocator corruption, which cascades into kernel
panics or undefined behavior.
Prevent trusting a corrupted allocator state by adding a validation
check during hfs_btree_open(). If corruption is detected, print a
warning identifying the specific corrupted tree and force the
filesystem to mount read-only (SB_RDONLY).
This prevents kernel panics from corrupted images while enabling
data recovery (Shardul Bankar)
- Fix a potential deadlock in hfsplus_fill_super().
hfsplus_fill_super() calls hfs_find_init() to initialize a search
structure, which acquires tree->tree_lock. If the subsequent call
to hfsplus_cat_build_key() fails, the function jumps to the
out_put_root error label without releasing the lock.
Fix this by adding the missing hfs_find_exit(&fd) call before
jumping to the out_put_root error label. This ensures that
tree->tree_lock is properly released on the error path (Zilin Guan)
- Update a files ctime after rename in hfsplus_rename() (Yangtao Li)
The rest of the patches introduce the HFS+ fixes for the case of
generic/348, generic/728, generic/533, generic/523, and generic/642
test-cases of xfstests suite"

sctp: fix missing encap_port propagation for GSO fragments
encap_port in SCTP_INPUT_CB(skb) is used by sctp_vtag_verify() for
SCTP-over-UDP processing. In the GSO case, it is only set on the head
skb, while fragment skbs leave it 0.
This results in fragment skbs seeing encap_port == 0, breaking
SCTP-over-UDP connections.
Fix it by propagating encap_port from the head skb cb when initializing
fragment skbs in sctp_inq_pop().
