chrome platform changes for 6.11
* New
- Add "cros_ec_hwmon" driver to expose fan speed and temperature.
- Add "cros_charge-control" driver to control charge thresholds and
behaviour.
- Add module parameter "log_poll_period_ms" in cros_ec_debugfs for
tuning the poll period.
- Support version 3 of EC_CMD_GET_NEXT_EVENT and keyboard matrix.
* Fixes
- Fix a race condition in accessing MEC (Microchip EC) memory between
ACPI and kernel. Serialize the memory access by an AML (ACPI
Machine Language) mutex.
- Fix an issue of wrong EC message version in cros_ec_debugfs.
* Misc
- Fix kernel-doc errors and cleanups.

arm64 updates for 6.11:
* Virtual CPU hotplug support for arm64 ACPI systems
* cpufeature infrastructure cleanups and making the FEAT_ECBHB ID bits
visible to guests
* CPU errata: expand the speculative SSBS workaround to more CPUs
* arm64 ACPI:
- acpi=nospcr option to disable SPCR as default console for arm64
- Move some ACPI code (cpuidle, FFH) to drivers/acpi/arm64/
* GICv3, use compile-time PMR values: optimise the way regular IRQs are
masked/unmasked when GICv3 pseudo-NMIs are used, removing the need for
a static key in fast paths by using a priority value chosen
dynamically at boot time
* arm64 perf updates:
- Rework of the IMX PMU driver to enable support for I.MX95
- Enable support for tertiary match groups in the CMN PMU driver
- Initial refactoring of the CPU PMU code to prepare for the fixed
instruction counter introduced by Arm v9.4
- Add missing PMU driver MODULE_DESCRIPTION() strings
- Hook up DT compatibles for recent CPU PMUs
* arm64 kselftest updates:
- Kernel mode NEON fp-stress
- Cleanups, spelling mistakes
* arm64 Documentation update with a minor clarification on TBI
* Miscellaneous:
- Fix missing IPI statistics
- Implement raw_smp_processor_id() using thread_info rather than a
per-CPU variable (better code generation)
- Make MTE checking of in-kernel asynchronous tag faults conditional
on KASAN being enabled
- Minor cleanups, typos

Updates for timers, timekeeping and related functionality:
- Core:
- Make the takeover of a hrtimer based broadcast timer reliable during
CPU hot-unplug. The current implementation suffers from a race which
can lead to broadcast timer starvation in the worst case.
- VDSO related cleanups and simplifications
- Small cleanups and enhancements all over the place
- PTP:
- Replace the architecture specific base clock to clocksource, e.g. ART
to TSC, conversion function with generic functionality to avoid
exposing such internals to drivers and convert all existing drivers
over. This also allows to provide functionality which converts the
other way round in the core code based on the same parameter set.
- Provide a function to convert CLOCK_REALTIME to the base clock to
support the upcoming PPS output driver on Intel platforms.
- Drivers:
- A set of Device Tree bindings for new hardware
- Cleanups and enhancements all over the place

A small set of SMP/CPU hotplug updates:
- Reverse the order of iteration when freezing secondary CPUs for
hibernation.
This avoids that drivers like the Intel uncore performance counter have
to transfer the assignement of handling the per package uncore events
for every CPU in a package, which is a considerable speedup on larger
systems.
- Add a missing destroy_work_on_stack() invocation in smp_call_on_cpu()
to prevent debug objects to emit a false positive warning when the
stack is freed.
- Small cleanups in comments and a str_plural() conversion

Pull CPU hotplug updates from Thomas Gleixner:
"A small set of SMP/CPU hotplug updates:
- Reverse the order of iteration when freezing secondary CPUs for
hibernation.
This avoids that drivers like the Intel uncore performance counter
have to transfer the assignement of handling the per package uncore
events for every CPU in a package, which is a considerable speedup
on larger systems.

The motivating use-case comes from LXCFS which is a tiny fuse filesystem used to virtualize various aspects of procfs. LXCFS is run on the host. The files and directories it creates can be bind-mounted by e.g. a container at startup and mounted over the various procfs files the container wishes to have virtualized. When e.g. a read request for uptime is received, LXCFS will receive the pid of the reader. In order to virtualize the corresponding read, LXCFS needs to know the pid of the init process of the reader's pid namespace. In order to do this, LXCFS first needs to fork() two helper processes. The first helper process setns() to the readers pid namespace. The second helper process is needed to create a process that is a proper member of the pid namespace. The second helper process then creates a ucred message with ucred.pid set to 1 and sends it back to LXCFS. The kernel will translate the ucred.pid field to the corresponding pid number in LXCFS's pid namespace. This way LXCFS can learn the init pid number of the reader's pid namespace and can go on to virtualize. Since these two forks() are costly LXCFS maintains an init pid cache that caches a given pid for a fixed amount of time. The cache is pruned during new read requests. However, even with the cache the hit of the two forks() is singificant when a very large number of containers are running. So this adds a simple set of ioctls that let's a caller translate PIDs from and into a given PID namespace. This significantly improves performance with a very simple change. To protect against races pidfds can be used to check whether the process is still valid" * tag 'vfs-6.11.nsfs' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: nsfs: add pid translation ioctls |

Merge tag 'vfs-6.11.mount' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull vfs mount query updates from Christian Brauner:
"This contains work to extend the abilities of listmount() and
statmount() and various fixes and cleanups.
Features:
- Allow iterating through mounts via listmount() from newest to
oldest. This makes it possible for mount(8) to keep iterating the
mount table in reverse order so it gets newest mounts first.
- Relax permissions on listmount() and statmount().
It's not necessary to have capabilities in the initial namespace:
it is sufficient to have capabilities in the owning namespace of
the mount namespace we're located in to list unreachable mounts in
that namespace.
- Extend both listmount() and statmount() to list and stat mounts in
foreign mount namespaces.
Currently the only way to iterate over mount entries in mount
namespaces that aren't in the caller's mount namespace is by
crawling through /proc in order to find /proc/<pid>/mountinfo for
the relevant mount namespace.
This is both very clumsy and hugely inefficient. So extend struct
mnt_id_req with a new member that allows to specify the mount
namespace id of the mount namespace we want to look at.
Luckily internally we already have most of the infrastructure for
this so we just need to expose it to userspace. Give userspace a
way to retrieve the id of a mount namespace via statmount() and
through a new nsfs ioctl() on mount namespace file descriptor.
This comes with appropriate selftests.
- Expose mount options through statmount().
Currently if userspace wants to get mount options for a mount and
with statmount(), they still have to open /proc/<pid>/mountinfo to
parse mount options. Simply the information through statmount()
directly.
Afterwards it's possible to only rely on statmount() and
listmount() to retrieve all and more information than
/proc/<pid>/mountinfo provides.
This comes with appropriate selftests.
Fixes:
- Avoid copying to userspace under the namespace semaphore in
listmount.
Cleanups:
- Simplify the error handling in listmount by relying on our newly
added cleanup infrastructure.
- Refuse invalid mount ids early for both listmount and statmount"

"This contains smaller performance improvements to inodes and dentries:
inode:
- Add rcu based inode lookup variants.
They avoid one inode hash lock acquire in the common case thereby
significantly reducing contention. We already support RCU-based
operations but didn't take advantage of them during inode
insertion.
Callers of iget_locked() get the improvement without any code
changes. Callers that need a custom callback can switch to
iget5_locked_rcu() as e.g., did btrfs.
With 20 threads each walking a dedicated 1000 dirs * 1000 files
directory tree to stat(2) on a 32 core + 24GB ram vm:
before: 3.54s user 892.30s system 1966% cpu 45.549 total
after: 3.28s user 738.66s system 1955% cpu 37.932 total (-16.7%)
Long-term we should pick up the effort to introduce more
fine-grained locking and possibly improve on the currently used
hash implementation.
- Start zeroing i_state in inode_init_always() instead of doing it in
individual filesystems.
This allows us to remove an unneeded lock acquire in new_inode()
and not burden individual filesystems with this.
dcache:
- Move d_lockref out of the area used by RCU lookup to avoid
cacheline ping poing because the embedded name is sharing a
cacheline with d_lockref.
- Fix dentry size on 32bit with CONFIG_SMP=y so it does actually end

Merge branch 'runtime-constants'
Merge runtime constants infrastructure with implementations for x86 and
arm64.
This is one of four branches that came out of me looking at profiles of
my kernel build filesystem load on my 128-core Altra arm64 system, where
pathname walking and the user copies (particularly strncpy_from_user()
for fetching the pathname from user space) is very hot.
This is a very specialized "instruction alternatives" model where the
dentry hash pointer and hash count will be constants for the lifetime of
the kernel, but the allocation are not static but done early during the
kernel boot. In order to avoid the pointer load and dynamic shift, we
just rewrite the constants in the instructions in place.
We can't use the "generic" alternative instructions infrastructure,
because different architectures do it very differently, and it's
actually simpler to just have very specific helpers, with a fallback to
the generic ("old") model of just using variables for architectures that
do not implement the runtime constant patching infrastructure.
Link: https://lore.kernel.org/all/CAHk-=widPe38fUNjUOmX11ByDckaeEo9tN4Eiyke9u1SAtu9sA@mail.gmail.com/
* runtime-constants:
arm64: add 'runtime constant' support
runtime constants: add x86 architecture support
runtime constants: add default dummy infrastructure
vfs: dcache: move hashlen_hash() from callers into d_hash()

Pull btrfs fixes from David Sterba:
"Fix a regression in extent map shrinker behaviour.
In the past weeks we got reports from users that there are huge
latency spikes or freezes. This was bisected to newly added shrinker
of extent maps (it was added to fix a build up of the structures in
memory).
I'm assuming that the freezes would happen to many users after release
so I'd like to get it merged now so it's in 6.10. Although the diff
size is not small the changes are relatively straightforward, the
reporters verified the fixes and we did testing on our side.
The fixes:
- adjust behaviour under memory pressure and check lock or scheduling
conditions, bail out if needed
- synchronize tracking of the scanning progress so inode ranges are
not skipped or work duplicated
- do a delayed iput when scanning a root so evicting an inode does
not slow things down in case of lots of dirty data, also fix
lockdep warning, a deadlock could happen when writing the dirty
data would need to start a transaction"

Currently the event counting provided by misc.events is hierarchical, it's not practical if user is only concerned with events of a specified cgroup. Therefore, introduce misc.events.local collect events specific to the given cgroup. This is analogous to memory.events.local and pids.events.local.

spi: Fixes for v6.10
This pull request fixes two regressions that have been bubbling along
for a large part of this release. One is a revert of the multi mode
support for the OMAP SPI controller, this introduced regressions on a
number of systems and while there has been progress on fixing those
we've not got something that works for everyone yet so let's just drop
the change for now. The other is a series of fixes from David Lechner
for his recent message optimisation work, this interacted badly with
spi-mux which is altogether too clever with recursive use of the bus and
creates situations that hadn't been considered.
There are also a couple of small driver specific fixes, including one
more patch from David for sleep duration calculations in the AXI driver.

trace_posix_lock_inode(). The tracepoint could fire while another
task raced it and freed the lock that was requested to be traced
- Only increment the nr_dentry_negative counter for dentries that are
present on the superblock LRU. Currently, DCACHE_LRU_LIST list is
used to detect this case. However, the flag is also raised in
combination with DCACHE_SHRINK_LIST to indicate that dentry->d_lru

nr_dentry_negative count. Fix the check to not count dentries that
are on a shrink related list

drm/xe: Use write-back caching mode for system memory on DGFX
The caching mode for buffer objects with VRAM as a possible placement was forced to write-combined, regardless of placement. However, write-combined system memory is expensive to allocate and even though it is pooled, the pool is expensive to shrink, since it involves global CPU TLB flushes. Moreover write-combined system memory from TTM is only reliably available on x86 and DGFX doesn't have an x86 restriction. So regardless of the cpu caching mode selected for a bo, internally use write-back caching mode for system memory on DGFX. Coherency is maintained, but user-space clients may perceive a difference in cpu access speeds. v2: - Update RB- and Ack tags. - Rephrase wording in xe_drm.h (Matt Roper) v3: - Really rephrase wording.

btrfs: avoid races when tracking progress for extent map shrinking
We store the progress (root and inode numbers) of the extent map shrinker in fs_info without any synchronization but we can have multiple tasks calling into the shrinker during memory allocations when there's enough memory pressure for example. This can result in a task A reading fs_info->extent_map_shrinker_last_ino after another task B updates it, and task A reading fs_info->extent_map_shrinker_last_root before task B updates it, making task A see an odd state that isn't necessarily harmful but may make it skip certain inode ranges or do more work than necessary by going over the same inodes again. These unprotected accesses would also trigger warnings from tools like KCSAN. So add a lock to protect access to these progress fields.

closures: fix closure_sync + closure debugging
originally, stack closures were only used synchronously, and with the original implementation of closure_sync() the ref never hit 0; thus, closure_put_after_sub() assumes that if the ref hits 0 it's on the debug list, in debug mode. that's no longer true with the current implementation of closure_sync, so we need a new magic so closure_debug_destroy() doesn't pop an assert.

sched.h: always_inline alloc_tag_{save|restore} to fix modpost warnings
Mark alloc_tag_{save|restore} as always_inline to fix the following
modpost warnings:
WARNING: modpost: vmlinux: section mismatch in reference: alloc_tag_save+0x1c (section: .text.unlikely) -> initcall_level_names (section: .init.data)
WARNING: modpost: vmlinux: section mismatch in reference: alloc_tag_restore+0x3c (section: .text.unlikely) -> initcall_level_names (section: .init.data)
The warnings happen when these functions are called from an __init
function and they don't get inlined (remain in the .text section) while
the value returned by get_current() points into .init.data section.
Assuming get_current() always returns a valid address, this situation can
happen only during init stage and accessing .init.data from .text section
during that stage should pose no issues.

spi: add defer_optimize_message controller flag
Adding spi_optimize_message() broke the spi-mux driver because it
calls spi_async() from it's transfer_one_message() callback. This
resulted in passing an incorrectly optimized message to the controller.
For example, if the underlying controller has an optimize_message()
callback, this would have not been called and can cause a crash when
the underlying controller driver tries to transfer the message.
Also, since the spi-mux driver swaps out the controller pointer by
replacing msg->spi, __spi_unoptimize_message() was being called with a
different controller than the one used in __spi_optimize_message(). This
could cause a crash when attempting to free the message resources when
__spi_unoptimize_message() is called in spi_finalize_current_message()
since it is being called with a controller that did not allocate the
resources.
This is fixed by adding a defer_optimize_message flag for controllers.
This flag causes all of the spi_[maybe_][un]optimize_message() calls to
be a no-op (other than attaching a pointer to the spi device to the
message).
This allows the spi-mux driver to pass an unmodified message to
spi_async() in spi_mux_transfer_one_message() after the spi device has
been swapped out. This causes __spi_optimize_message() and
__spi_unoptimize_message() to be called only once per message and with
the correct/same controller in each case.

bpf: Fix too early release of tcx_entry
Pedro Pinto and later independently also Hyunwoo Kim and Wongi Lee reported
an issue that the tcx_entry can be released too early leading to a use
after free (UAF) when an active old-style ingress or clsact qdisc with a
shared tc block is later replaced by another ingress or clsact instance.
Essentially, the sequence to trigger the UAF (one example) can be as follows:
1. A network namespace is created
2. An ingress qdisc is created. This allocates a tcx_entry, and
&tcx_entry->miniq is stored in the qdisc's miniqp->p_miniq. At the
same time, a tcf block with index 1 is created.
3. chain0 is attached to the tcf block. chain0 must be connected to
the block linked to the ingress qdisc to later reach the function
tcf_chain0_head_change_cb_del() which triggers the UAF.
4. Create and graft a clsact qdisc. This causes the ingress qdisc
created in step 1 to be removed, thus freeing the previously linked
tcx_entry:
rtnetlink_rcv_msg()
=> tc_modify_qdisc()
=> qdisc_create()
=> clsact_init() [a]
=> qdisc_graft()
=> qdisc_destroy()
=> __qdisc_destroy()
=> ingress_destroy() [b]
=> tcx_entry_free()
=> kfree_rcu() // tcx_entry freed
5. Finally, the network namespace is closed. This registers the
cleanup_net worker, and during the process of releasing the
remaining clsact qdisc, it accesses the tcx_entry that was
already freed in step 4, causing the UAF to occur:
cleanup_net()
=> ops_exit_list()
=> default_device_exit_batch()
=> unregister_netdevice_many()
=> unregister_netdevice_many_notify()
=> dev_shutdown()
=> qdisc_put()
=> clsact_destroy() [c]
=> tcf_block_put_ext()
=> tcf_chain0_head_change_cb_del()
=> tcf_chain_head_change_item()
=> clsact_chain_head_change()
=> mini_qdisc_pair_swap() // UAF
There are also other variants, the gist is to add an ingress (or clsact)
qdisc with a specific shared block, then to replace that qdisc, waiting
for the tcx_entry kfree_rcu() to be executed and subsequently accessing
the current active qdisc's miniq one way or another.
The correct fix is to turn the miniq_active boolean into a counter. What
can be observed, at step 2 above, the counter transitions from 0->1, at
step [a] from 1->2 (in order for the miniq object to remain active during
the replacement), then in [b] from 2->1 and finally [c] 1->0 with the
eventual release. The reference counter in general ranges from [0,2] and
it does not need to be atomic since all access to the counter is protected
by the rtnl mutex. With this in place, there is no longer a UAF happening
and the tcx_entry is freed at the correct time.

Merge patch series "cachefiles: random bugfixes"
libaokun@huaweicloud.com <libaokun@huaweicloud.com> says: This is the third version of this patch series, in which another patch set is subsumed into this one to avoid confusing the two patch sets. (https://patchwork.kernel.org/project/linux-fsdevel/list/?series=854914) We've been testing ondemand mode for cachefiles since January, and we're almost done. We hit a lot of issues during the testing period, and this patch series fixes some of the issues. The patches have passed internal testing without regression. The following is a brief overview of the patches, see the patches for more details. Patch 1-2: Add fscache_try_get_volume() helper function to avoid fscache_volume use-after-free on cache withdrawal. Patch 3: Fix cachefiles_lookup_cookie() and cachefiles_withdraw_cache() concurrency causing cachefiles_volume use-after-free. Patch 4: Propagate error codes returned by vfs_getxattr() to avoid endless loops. Patch 5-7: A read request waiting for reopen could be closed maliciously before the reopen worker is executing or waiting to be scheduled. So ondemand_object_worker() may be called after the info and object and even the cache have been freed and trigger use-after-free. So use cancel_work_sync() in cachefiles_ondemand_clean_object() to cancel the reopen worker or wait for it to finish. Since it makes no sense to wait for the daemon to complete the reopen request, to avoid this pointless operation blocking cancel_work_sync(), Patch 1 avoids request generation by the DROPPING state when the request has not been sent, and Patch 2 flushes the requests of the current object before cancel_work_sync(). Patch 8: Cyclic allocation of msg_id to avoid msg_id reuse misleading the daemon to cause hung. Patch 9: Hold xas_lock during polling to avoid dereferencing reqs causing use-after-free. This issue was triggered frequently in our tests, and we found that anolis 5.10 had fixed it. So to avoid failing the test, this patch is pushed upstream as well. Baokun Li (7): netfs, fscache: export fscache_put_volume() and add fscache_try_get_volume() cachefiles: fix slab-use-after-free in fscache_withdraw_volume() cachefiles: fix slab-use-after-free in cachefiles_withdraw_cookie() cachefiles: propagate errors from vfs_getxattr() to avoid infinite loop cachefiles: stop sending new request when dropping object cachefiles: cancel all requests for the object that is being dropped cachefiles: cyclic allocation of msg_id to avoid reuse Hou Tao (1): cachefiles: wait for ondemand_object_worker to finish when dropping object Jingbo Xu (1): cachefiles: add missing lock protection when polling fs/cachefiles/cache.c | 45 ++++++++++++++++++++++++++++- fs/cachefiles/daemon.c | 4 +-- fs/cachefiles/internal.h | 3 ++ fs/cachefiles/ondemand.c | 52 ++++++++++++++++++++++++++++++---- fs/cachefiles/volume.c | 1 - fs/cachefiles/xattr.c | 5 +++- fs/netfs/fscache_volume.c | 14 +++++++++ fs/netfs/internal.h | 2 -- include/linux/fscache-cache.h | 6 ++++ include/trace/events/fscache.h | 4 +++ 10 files changed, 123 insertions(+), 13 deletions(-) Link: https://lore.kernel.org/r/20240628062930.2467993-1-libaokun@huaweicloud.com Signed-off-by: Christian Brauner <brauner@kernel.org> |

blk-lib: check for kill signal in ioctl BLKZEROOUT
Zeroout can access a significant capacity and take longer than the user expected. A user may change their mind about wanting to run that command and attempt to kill the process and do something else with their device. But since the task is uninterruptable, they have to wait for it to finish, which could be many hours. Add a new BLKDEV_ZERO_KILLABLE flag for blkdev_issue_zeroout that checks for a fatal signal at each iteration so the user doesn't have to wait for their regretted operation to complete naturally. Heavily based on an earlier patch from Keith Busch. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Martin K.

block: Remove REQ_OP_ZONE_RESET_ALL emulation
Now that device mapper can handle resetting all zones of a mapped zoned device using REQ_OP_ZONE_RESET_ALL, all zoned block device drivers support this operation. With this, the request queue feature BLK_FEAT_ZONE_RESETALL is not necessary and the emulation code in blk-zone.c can be removed.

dm: handle REQ_OP_ZONE_RESET_ALL
This commit implements processing of the REQ_OP_ZONE_RESET_ALL operation for zoned mapped devices. Given that this operation always has a BIO sector of 0 and a 0 size, processing through the regular BIO __split_and_process_bio() function does not work because this function would always select the first target. Instead, handling of this operation is implemented using the function __send_zone_reset_all(). Similarly to the __send_empty_flush() function, the new __send_zone_reset_all() function manually goes through all targets of a mapped device table doing the following: 1) If the target can natively support REQ_OP_ZONE_RESET_ALL, __send_duplicate_bios() is used to forward the reset all operation to the target. This case is handled with the __send_zone_reset_all_native() function. 2) For other targets, the function __send_zone_reset_all_emulated() is executed to emulate the execution of REQ_OP_ZONE_RESET_ALL using regular REQ_OP_ZONE_RESET operations. Targets that can natively support REQ_OP_ZONE_RESET_ALL are identified using the new target field zone_reset_all_supported. This boolean is set to true in for targets that have reliable zone limits, that is, targets that map all sequential write required zones of their zoned device(s). Setting this field is handled in dm_set_zones_restrictions() and device_get_zone_resource_limits(). For targets with unreliable zone limits, REQ_OP_ZONE_RESET_ALL must be emulated (case 2 above). This is implemented with __send_zone_reset_all_emulated() and is similar to the block layer function blkdev_zone_reset_all_emulated(): first a report zones is done for the zones of the target to identify zones that need reset, that is, any sequential write required zone that is not already empty. This is done using a bitmap and the function dm_zone_get_reset_bitmap() which sets to 1 the bit corresponding to a zone that needs reset. Next, this zone bitmap is inspected and a clone BIO modified to use the REQ_OP_ZONE_RESET operation issued for any zone with its bit set in the zone bitmap. This implementation is more efficient than what the block layer does with blkdev_zone_reset_all_emulated(), which is always used for DM zoned devices currently: as we can natively use REQ_OP_ZONE_RESET_ALL on targets mapping all sequential write required zones, resetting all zones of a zoned mapped device can be much faster compared to always emulating this operation using regular per-zone reset. In the worst case, this implementation is as-efficient as the block layer emulation. This reduction in the time it takes to reset all zones of a zoned mapped device depends directly on the mapped device targets mapping (reliable zone limits or not).

tpm: Address !chip->auth in tpm_buf_append_hmac_session*()
Unless tpm_chip_bootstrap() was called by the driver, !chip->auth can
cause a null derefence in tpm_buf_hmac_session*(). Thus, address
!chip->auth in tpm_buf_hmac_session*() and remove the fallback

Including fixes from bluetooth, wireless and netfilter.
There's one fix for power management with Intel's e1000e here,
Thorsten tells us there's another problem that started in v6.9.
We're trying to wrap that up but I don't think it's blocking.
Current release - new code bugs:
- wifi: mac80211: disable softirqs for queued frame handling
- af_unix: fix uninit-value in __unix_walk_scc(), with the new garbage
collection algo
Previous releases - regressions:
- Bluetooth:
- qca: fix BT enable failure for QCA6390 after warm reboot
- add quirk to ignore reserved PHY bits in LE Extended Adv Report,
abused by some Broadcom controllers found on Apple machines
- wifi: wilc1000: fix ies_len type in connect path
Previous releases - always broken:
- tcp: fix DSACK undo in fast recovery to call tcp_try_to_open(),
avoid premature timeouts
- net: make sure skb_datagram_iter maps fragments page by page,
in case we somehow get compound highmem mixed in
- eth: bnx2x: fix multiple UBSAN array-index-out-of-bounds when
more queues are used
