ip6mr: Use MAXMIFS in mr6_msgsize().
mr6_msgsize() calculates skb size needed for ip6mr_fill_mroute(). The size differs based on mrt->maxvif. We will drop RTNL for ip6mr_rtm_getroute() and mrt->maxvif may change under RCU. To avoid -EMSGSIZE, let's calculate the size with the maximum value of mrt->maxvif, MAXMIFS. struct rtnexthop is 8 bytes and MAXMIFS is 32, so the maximum delta is 256 bytes, which is small enough.

ip6mr: Annotate access to mrt->mroute_do_{pim,assert,wrvifwhole}.
These fields in struct mr_table are updated in ip6_mroute_setsockopt() under RTNL: * mroute_do_pim * mroute_do_assert (MRT6_PIM is under RTNL while MRT6_ASSERT is lockless) * mroute_do_wrvifwhole However, ip6_mroute_getsockopt() does not hold RTNL and read the first two fields locklessly, and ip6_mr_forward() reads all the three under RCU. Let's use WRITE_ONCE() and READ_ONCE() for them.

Merge branch 'so_txtime-improvements'
Willem de Bruijn says: ==================== SO_TXTIME improvements FQ targets monotonic timestamps as generated by the TCP stack. But SO_TXTIME was later added, which can send skbs with timestamps against other clocks. It is now possible to detect these through skb tstamp_type. Make FQ robust by converting these timestamps for use in FQ (patch 2). This also requires testing against out-of-bounds values. Prefer to do this at the source, when parsing SCM_TXTIME (patch 1). But, tests in the hot path are still needed, to handle BPF sources. Extend the so_txtime selftest to handle this new case (patch 3). v1: https://lore.kernel.org/20260603190243.2789335-1-willemdebruijn.kernel@gmail.com ==================== Link: https://patch.msgid.link/20260604194221.3319080-1-willemdebruijn.kernel@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

selftests: drv-net: extend so_txtime with FQ with other clocks
Add a variant of the existing FQ tests, but pass CLOCK_TAI rather than the native CLOCK_MONOTONIC clock id. FQ used to imply monotonic. This is no longer the case, and the inverse need not hold either. Rename $PREFIX_mono to $PREFIX_fq.

net_sched: sch_fq: convert skb->tstamp if not monotonic
FQ currently assumes skb->tstamp holds monotonic time, as used by TCP. Users with ns_capable CAP_NET_ADMIN can transmit skbs using SO_TXTIME with CLOCK_MONOTONIC, CLOCK_REALTIME or CLOCK_TAI clockids as of commit |

net: ensure SCM_TXTIME delivery time is no older than system boot
Limit input to sane values to avoid having to add tests later in the
kernel hot path, e.g., in FQ.
SCM_TXTIME timestamps are converted to signed ktime_t when assigned to
skb->tstamp. Avoid having negative values overflow into large positive
ones when again used as u64, e.g., in FQ time_to_send.
For CLOCK_MONOTONIC, only allow positive values.
For CLOCK_REALTIME and CLOCK_TAI, allow equivalent values, i.e., no
older than the boot of the machine.
skb->tstamp zero is a special case signaling feature off. This is not
converted between clockids.
Handle the special case where the realtime clock is set so small that
real - mono is negative, however unlikely in practice.
Ideally we would also set a sane upper bound, but that would require
reading the clock, which is an expensive operation. Continue to defer
that validation to users of the data. FQ already does this.
Bound rather than return error on older timestamps. This is the
existing policy e.g., in FQ.

Pablo Neira Ayuso says:
====================
Netfilter/IPVS updates for net-next
The following patchset contains Netfilter/IPVS updates for net-next,
this contains updates to address sashiko reports in IPVS and Netfilter
on possible pre-existing issues. This also includes a series to add
refcount for ct helper and timeout to deal with a corner case scenario
with unconfirmed conntracks flying to nfqueue.
1) Add a conn_max sysctl to IPVS to limit the maximum number of
connections, from Julian Anastasov.
2) Use get_unaligned_be16() to access TCP MSS in nfnetlink_osf,
from Fernando Fernandez Mancera.
3) Use {READ,WRITE}_ONCE to access helper flags from nfnetlink_helper.
Several patches for the synproxy infrastructure, from Fernando
Fernandez Mancera:
4) Drop packet if TCP timestamp adjustment fails.
5) Continue parsing of TCP timestamp to deal with possible duplicates.
6) Use {get,put}_unaligned_be32() to acess the TCP timestamp.
7) Hold ct->lock to initialize nf_ct_seqadj_init().
Updates for the ct timeout infrastructure, to deal with a corner case
for unconfirmed conntracks flying to nfqueue:
8) Add a refcount to track ct timeout policy use by ct extension,
release the timeout until the last ct extension drops the refcnt
on it.
Similar update for the ct helper infrastructure:
9) Dynamic allocation of ct helpers, as a preparation for adding
refcount to track ct extension use.
10) Move destroy_sibling_or_exp() to nf_conntrack_proto_gre, so
pptp conntrack helper module removal does not make this code
unreachable via the helper->destroy callback. This is another
dependency for the new refcount coming in this series.
11) Add a refcount to track use of it from the ct extension, then
ct helper and timeout is reachable to the connection until
it goes away.
12) Remove the genid infrastructure in ct extensions. The primary
goal was to detect that a ct extension such as ct timeout and
ct helper went stale for unconfirmed conntrack, either because
object or module was removed. This deactivates all ct extensions
though for this unconfirmed conntrack.
13) Call nf_ct_gre_keymap_destroy() if this is a master conntrack
with a pptp helper only.
sashiko.dev reports one more relevant issue when unsetting the helper
via ctnetlink that I will address in a follow up patch.
Then, two more assorted updates:
14) Avoid a unlikely underflow in bridge VLAN untag, only possible
if buggy bridge VLAN filtering is buggy, remove WARN_ON_ONCE
while at it. From David Carlier.
15) Use get_unaligned_be32() in nf_conntrack_tcp to access sack
extension, from Rosen Penev.

scsi: target: Remove tcm_loop target reset handling
tcm_loop_target_reset is supposed to handle all the LUNs on a target but
it's only doing a TMR_LUN_RESET so only that one LUN is handled. This
will cause us to return early while IOs to other LUNs are still hung in
lower layers. This just removes the target reset handler for the driver
because LIO doesn't support target resets and for the common case where
this is run from the scsi-ml error hamdler we have already tried an
abort and lun reset so waiting again is most likely useless.

scsi: ufs: core: Handle PM commands timeout before SCSI EH
A PM START STOP sent from the UFS well-known LU resume path can race
with SCSI EH:
The "wl resume" task flow is:
__ufshcd_wl_resume()
ufshcd_set_dev_pwr_mode(UFS_ACTIVE_PWR_MODE)
ufshcd_execute_start_stop()
scsi_execute_cmd()
blk_execute_rq <-- wait
scsi_check_passthrough() <-- may retry START STOP
If the first START STOP time out, SCSI EH may already recover the link and
reset the device before scsi_execute_cmd() returns:
scsi_timeout()
scsi_eh_scmd_add()
scsi_error_handler()
scsi_unjam_host()
scsi_eh_ready_devs()
scsi_eh_host_reset()
ufshcd_eh_host_reset_handler()
if (hba->pm_op_in_progress)
ufshcd_link_recovery()
ufshcd_device_reset()
ufshcd_host_reset_and_restore()
...
scsi_eh_flush_done_q() <-- wakeup "wl resume" task
... <-- host still in SHOST_RECOVERY
scsi_restart_operations()
A later passthrough retry can then run while the host is still in
SHOST_RECOVERY and hit the SCMD_FAIL_IF_RECOVERING path:
scsi_queue_rq()
if (scsi_host_in_recovery(shost) &&
cmd->flags & SCMD_FAIL_IF_RECOVERING)
return BLK_STS_OFFLINE
That retry completes with DID_ERROR or DID_NO_CONNECT even though EH may
already have restored the device to an operational ACTIVE state.
Handle these PM timeouts directly from ufshcd_eh_timed_out() instead.
After ufshcd_link_recovery(), complete the timed-out command immediately
if it has not been completed already.
For regular SCSI commands, complete them with DID_REQUEUE to match the
existing MCQ force-completion semantics and allow scsi_execute_cmd() to
retry if needed. For reserved internal device-management commands,
finish the request with DID_TIME_OUT without calling
ufshcd_release_scsi_cmd() since those commands use different resource
lifetime rules.
The system_suspending flag is no longer needed because PM command
timeout handling now uses pm_op_in_progress.

The Promise VTrak Ex10 series share the same hardware base and firmware.
Consequently all interface variants, whether fibre channel ("f") or SAS

Instead of adding separate blacklist entries for every specific model

the match strings to "VTrak E310" and "VTrak E610".

Currently building with C=1 generates the following warning: CC drivers/nvme/host/core.o CHECK drivers/nvme/host/core.c drivers/nvme/host/core.c:2426:13: warning: unsigned value that used to be signed checked against zero? drivers/nvme/host/core.c:2426:13: signed value source This issue was introduced when using check_shl_overflow() to check for invalid LBA size. Sparse is having trouble dealing with __bitwise __le64 conversion when passing to check_shl_overflow(). Resolve the issue by moving the check_shl_overflow() call to a separate function, where types are not converted. The id->lbaf[lbaf].ds < SECTOR_SHIFT check is dropped as check_shl_overflow() is able to detect negative shifts.

driver core: platform: set mod_name in driver registration
Pass KBUILD_MODNAME through the driver registration macro so that the
driver core can create the module symlink in sysfs for built-in drivers,
and fixup all callers.
The Rust platform adapter is updated to pass the module name through to
the new parameter.
Tested on qemu with:
- x86 defconfig + CONFIG_RUST
- arm64 defconfig + CONFIG_RUST + CONFIG_CORESIGHT stuff
Examples after this patch:
/sys/bus/platform/drivers/...
coresight-itnoc/module -> coresight_tnoc
coresight-static-tpdm/module -> coresight_tpdm
coresight-catu-platform/module -> coresight_catu
serial8250/module -> 8250
acpi-ged/module -> acpi
vmclock/module -> ptp_vmclock

kernel: param: initialize module_kset in a pure_initcall
Commit "driver core: platform: set mod_name in driver registration" will set struct device_driver's mod_name member for platform driver registration. For a driver to be registered with its mod_name set, module_kset needs to be initialized, which currently happens in a subsys_initcall in param_sysfs_init(). The tegra cbb drivers register themselves before module_kset init, in a core_initcall. This works currently because lookup_or_create_module_kobject(), which dereferences module_kset via kset_find_obj(), is not called if mod_name is not set, which is the case now. So in preparation for the commit "driver core: platform: set mod_name in driver registration", move module_kset init to pure_initcall level, ensuring it happens before tegra cbb driver registration.

scsi: target: Use constant-time crypto_memneq() for CHAP digests
A constant-time memory comparison is more suitable than plain memcmp() for authentication digest comparison. CHAP digests use an authenticator-provided random challenge, so any timing side-channel shouldn't be easily exploitable. Reported-by: Sashiko (gemini/gemini-3.1-pro-preview) Link: https://sashiko.dev/#/patchset/20260521151121.808477-1-hossu.alexandru%40gmail.com Signed-off-by: David Disseldorp <ddiss@suse.de> Reviewed-by: Lee Duncan <lduncan@suse.com> Link: https://patch.msgid.link/20260605122019.24146-3-ddiss@suse.de Signed-off-by: Martin K.

scsi: target: Fix hexadecimal CHAP_I handling
A mutual CHAP handshake requires target processing of an initiator-sent
CHAP_I identifier. The RFC 3720 specification states:
11.1.4. Challenge Handshake Authentication Protocol (CHAP)
...
CHAP_A=<A> CHAP_I=<I> CHAP_C=<C>
...
Where N, (A,A1,A2), I, C, and R are (correspondingly) the Name,
Algorithm, Identifier, Challenge, and Response as defined in
[RFC1994], N is a text string, A,A1,A2, and I are numbers
CHAP_I parsing currently calls extract_param(), which returns the
@identifier string (stripped of any 0b/0B or 0x/0X prefix) and a @type
which indicates DECIMAL, HEX, or BASE64 encoding (based on any stripped
prefix).
Any HEX encoded CHAP_I string is further processed via:
ret = kstrtoul(&identifier[2], 0, &id);
This is incorrect for two reasons:
* The @identifier string has already been stripped of the 0x/0X prefix,
so skipping the first two bytes omits part of the number.
* The kstrtoul() call specifies a base of 0, which will see
&identifier[2] parsed as a decimal, unless a '0x' or (octal) '0' is
erroneously present at that offset.
Fix this by passing the (zero-offset) identifier string to kstrtoul()
along with a base=16 parameter. Also add an explicit error handler for
BASE64 encoding.
Hex-encoded CHAP_I handling can be testing using the libiscsi EncodedI
test linked below.

scsi: scsi_debug: Fix one-partition tape setup bounds
The tape setup path uses one tape_block entry as the end-of-data marker after the usable tape blocks. For the one-partition layout, partition 0 uses all TAPE_UNITS data slots and partition 1's marker is written at tape_blocks[0] + TAPE_UNITS. Only TAPE_UNITS entries are allocated, so that marker write is one element past the allocation during device initialization before any command is issued. Allocate one extra tape_block entry for the marker. This keeps the existing partitioning paths unchanged while providing backing storage for the sentinel.

w1: ds2482: Use named initializers for arrays of i2c_device_data
While being less compact, using named initializers allows to more easily see which members of the structs are assigned which value without having to lookup the declaration of the struct. And it's also more robust against changes to the struct definition. The mentioned robustness is relevant for a planned change to struct i2c_device_id that replaces .driver_data by an anonymous union. This patch doesn't modify the compiled arrays, only their representation in source form benefits. The former was confirmed with x86 and arm64 builds.

IIO: New device support, features and cleanup for the 7.2 cycle.
Like many areas of the kernel IIO has seen a lot of new contributors though in this case that is not all AI driven, but also reflects and annual surge of student contributions from usp.br. We also have several new regular reviewers who are helping with the surge (thanks to all our active reviewers!) Given there was a lot of cases of similar improvements applied to different drivers, I have grouped those into a special section (various drivers) to avoid mass duplication. New device support ------------------ adi,ad4130 - Add support for AD4129-4, AD4129-8, AD4130-4, AD4131-4 and AD4131-8 after reworking the driver to be suitable for multiple device support. adi,ad4080 - Support the AD4880 and AD4884 dual-channel parts. Interesting parts as have two separate data pipelines (including SPI buses interfaces), but the only current backend IP combines the two so they cannot be treated as independent devices. adi,ad5706r - New driver for this 4 channel current output DAC. adi,ad4691 - New driver supporting this family of ADCs. Support for AD4691, AD4692, AD4693 and AD4694 which support either 8 or 16 channels with different max sampling rates. Feature rich driver including SPI offload support. adi,ltc2983 - Add support for the ADT7604 in which the same sensor die as the LTC2984 is used for leak detection (liquid coverage of a sense area). allwinner,adc - Support for A523 SoCs. Similar to existing parts but with an additional clock. Includes adding support for non contiguous channel lookup for in kernel use (fwnode_xlate callback). broadcomm,apds9999 - New driver for the APDS9999 Ambient Light, RGB and proximity sensor. memsic,mmc5983 - New driver for this 3-axis magnetometer. taos,tsl2772 - Add support for the AVAGO APDS9900 and APDS9901 Ambient Light and Proximity sensors. which are very similar to existing part with slightly different integration time choices. Includes removal of driver for these parts from drivers/misc. vishay,veml3328 - New driver for this RGB+IR light sensor. Features -------- IIO Core - Support for IEEE 754 floating point values in buffer scan elements. - Support quaternion axis representation (missing the scaler part) microchip,mcp4821 - Add configurable gain control qcom,pm8xxx-xoadc - Add per channel labels. st,lsm6dsx - Support for rotation sensing on the LSM6DSV and LSM6DSV16X using both floating point and new quaterionaxis rotation modifier. MAINTAINERS update ------------------ IIO top level entry - Include Documentation/driver-api/iio/ adi,* - Top level ADI entry maintainer switch from Lars-Peter Clausen to Nuno Sá reflecting what has been the reality for some time. Thanks to Lars-Peter who was very active for many years, but has moved on to other things. Also add the linux@analog.com email list to ensure we don't get a gap in future. - Maintainer updates to reflect Cosmin Tanislav having moved on - thanks to Marcelo Schmitt for taking these over. sensiron,scd30 - Replace maintainer (Tomasz Duszynski) with Maxwell Doose. Cleanups, minor fixes and hardening. ------------------------------------ Documentation - Add missing powerdown modes to ABI docs. - Use modern helpers for buffer definition in the examples. core - Rework of the handling of timestamps so that the offset is cached at buffer resize time (during enabling) rather than based on assumption that relied in the timestamp being last and the largest element and so always 8 bytes before end of the scan. Underlying problem was triggered by scans with repeated type elements such as quaternions with each element more than 2 bytes - Giving a 16 byte+ aligned channel with result that a following timestamp may be 16 bytes from end of scan, rather than 8. Note that for the bosch,bno55 a compatibility hack means that it will duplicate the timestamp putting a second copy at previously incorrect location. - Tidy up use of kernel types in buffer code to not use int64_t given all calls use s64. various drivers - Drop unused driver_data in device id tables - includes cleanup of various drivers that had only one choice where it can be hard coded elsewhere. - Move to named initializers for many i2c_device_id and platform_device_id tables (I have no idea how we go into habit of using named initializers for only a subset of the table types - e.g. of_device_id). - Make IIO_CHAN_SOFT_TIMESTAMP() macro a compound literal allowing simple use in various drivers that do dynamic channel definitions. Use it in all such cases. - Use dev_err_probe() and local dev variables to tidy up older drivers. - Switch more drivers to devm_mutex_init() to provide minor debug benefits. - Reorder code to put MODULE_DEVICE_TABLE() next to the tables. - Lots of use of cleanup.h magic to improve code flow, often including related refactors such as introducing helpers. - Replacement of usleep_range() with fsleep() - Reduce logging noise where functions either provide their own extensive reports on error, or where a clear error code is returned to userspace. - Minor spelling and style fixes (improving bracket usage, not using __packed etc) hid-sensors-* - Drop helpers for setting channel bit masks in favor of a compound literal at the call site. Also general cleanup of surrounding code. hid-sensors-magn - Use u32 rather than bare unsigned for types. hid-sensors-rotation - Make sue of ext_scan_type handling for static case rather than duplicate chan_info structures. adi,ad3552r - Use field_get() to replace open coded equivalent. adi,ad4170 - Switch from switch to table lookup for GPIO modes. adi,ad5686 - Apply IWYU principal to included a consistent set of headers. - Deduplicate regmaps for AD5684 and AD5693 as identical. - Switch from an enum value in driver data and array look up to pointers to separate structures, improving readabilty and avoiding issues with 0 value when using helpers to deal with different firmware types. - Add of_match_id table to SPI driver rather than relying on fallback to spi_device_id table. - Introduce some helpers for powerdown mask control. - Add helpers for control sync simplifying a couple of corner cases. - Docs fixes. - Add an ops structure to simplify future addition of operations beyond read and write. adi,ad7191 - Switch to best practice of using device_property_present() to detect if an optional property is there rather than error values on querying the property. adi,ad7280a -

Like many areas of the kernel IIO has seen a lot of new contributors though in this case that is not all AI driven, but also reflects and annual surge of student contributions from usp.br. We also have several new regular reviewers who are helping with the surge (thanks to all our active reviewers!) Given there was a lot of cases of similar improvements applied to different drivers, I have grouped those into a special section (various drivers) to avoid mass duplication. New device support ------------------ adi,ad4130 - Add support for AD4129-4, AD4129-8, AD4130-4, AD4131-4 and AD4131-8 after reworking the driver to be suitable for multiple device support. adi,ad4080 - Support the AD4880 and AD4884 dual-channel parts. Interesting parts as have two separate data pipelines (including SPI buses interfaces), but the only current backend IP combines the two so they cannot be treated as independent devices. adi,ad5706r - New driver for this 4 channel current output DAC. adi,ad4691 - New driver supporting this family of ADCs. Support for AD4691, AD4692, AD4693 and AD4694 which support either 8 or 16 channels with different max sampling rates. Feature rich driver including SPI offload support. adi,ltc2983 - Add support for the ADT7604 in which the same sensor die as the LTC2984 is used for leak detection (liquid coverage of a sense area). allwinner,adc - Support for A523 SoCs. Similar to existing parts but with an additional clock. Includes adding support for non contiguous channel lookup for in kernel use (fwnode_xlate callback). broadcomm,apds9999 - New driver for the APDS9999 Ambient Light, RGB and proximity sensor. memsic,mmc5983 - New driver for this 3-axis magnetometer. taos,tsl2772 - Add support for the AVAGO APDS9900 and APDS9901 Ambient Light and Proximity sensors. which are very similar to existing part with slightly different integration time choices. Includes removal of driver for these parts from drivers/misc. vishay,veml3328 - New driver for this RGB+IR light sensor. Features -------- IIO Core - Support for IEEE 754 floating point values in buffer scan elements. - Support quaternion axis representation (missing the scaler part) microchip,mcp4821 - Add configurable gain control qcom,pm8xxx-xoadc - Add per channel labels. st,lsm6dsx - Support for rotation sensing on the LSM6DSV and LSM6DSV16X using both floating point and new quaterionaxis rotation modifier. MAINTAINERS update ------------------ IIO top level entry - Include Documentation/driver-api/iio/ adi,* - Top level ADI entry maintainer switch from Lars-Peter Clausen to Nuno Sá reflecting what has been the reality for some time. Thanks to Lars-Peter who was very active for many years, but has moved on to other things. Also add the linux@analog.com email list to ensure we don't get a gap in future. - Maintainer updates to reflect Cosmin Tanislav having moved on - thanks to Marcelo Schmitt for taking these over. sensiron,scd30 - Replace maintainer (Tomasz Duszynski) with Maxwell Doose.

pinctrl: qcom: Modify MSM_PULL_MASK to accurately represent PULL bits
MSM_PULL_MASK currently spans bits [2:0], but the GPIO_PULL field in the GPIO_CFG register only occupies bits [1:0]. Bit 2 belongs to FUNC_SEL. MSM_PULL_MASK is used to isolate the GPIO_PULL bits before writing the pull configuration (PULL_DOWN: 0x1, PULL_UP: 0x3) to the GPIO_CFG register. Narrow it to bits [1:0] to prevent unintended modification of the FUNC_SEL field. This causes no functional change since the driver currently does not modify the FUNC_SEL bit, but align the mask with hardware configuration nonetheless.

i2c: tegra: Disable fair arbitration for non-MCTP buses
Recent Tegra I2C controllers have a fairness arbitration register, which allows configuring the fair idle time required to support MCTP protocol over I2C. It is enabled by default, adding a per-transfer latency overhead that impacts non-MCTP I2C buses. Disable the fairness arbitration register during controller init for buses that are not MCTP controllers.

i2c: tegra: use dmaengine_get_dma_device() for DMA buffer allocation
Use dmaengine_get_dma_device() to obtain the correct struct device pointer for dma_alloc_coherent() instead of directly dereferencing chan->device->dev. The dmaengine_get_dma_device() helper checks whether the DMA channel has a per-channel DMA device (chan->dev->chan_dma_dev) and returns it when available, falling back to the controller device otherwise. On platforms where the DMA controller sits behind an IOMMU with per-channel IOVA spaces (e.g. Tegra264 GPC DMA), the per-channel device carries the correct DMA mapping context. Using the controller device directly would allocate DMA buffers against the wrong IOMMU domain, leading to SMMU faults at runtime. On platforms without per-channel DMA devices the helper returns the same pointer as before, so there is no change in behavior for existing hardware.

i2c: tegra: Fix NOIRQ suspend/resume
The Tegra I2C driver relies on runtime PM to wake up the controller before
each transfer. However, runtime PM is disabled between the system suspend
and NOIRQ suspend. If an I2C device initiates a transfer during this
window, the I2C controller fails to wake up and the transfer fails. To
handle this, the controller must be kept available for this period to
allow transfers.
Rework the I2C controller's system PM callbacks such that the controller
is resumed from runtime suspend during system suspend and it stays
RPM_ACTIVE throughout the suspend-resume cycle until it is runtime
suspended back in the system resume. The clocks are disabled in NOIRQ
suspend and enabled back in NOIRQ resume by calling the controller's
runtime PM functions directly.
