3bf83e47b4 VFIO fixes for v7.1-rc4
- Convert vfio-pci BAR resource requests and iomaps initialization
    from a lazy, on-demand model to an eager pre-allocation model to
    avoid races while preserving legacy error behavior.  Fix unchecked
    barmap access in dma-buf export path. (Matt Evans)
 
  - Introduce an implicit unsigned cast in converting vfio-pci device
    offsets to region indexes, closing a potential out-of-bounds
    access through the vfio_pci_ioeventfd() interface. (Matt Evans)
 
  - Fix a dma-buf kref underflow and stuck wait_for_completion() when
    closing a previously revoked dma-buf. (Alex Williamson)

31e62c2ebb ptrace: slightly saner 'get_dumpable()' logic
The 'dumpability' of a task is fundamentally about the memory image of
the task - the concept comes from whether it can core dump or not - and
makes no sense when you don't have an associated mm.

And almost all users do in fact use it only for the case where the task
has a mm pointer.

But we have one odd special case: ptrace_may_access() uses 'dumpable' to
check various other things entirely independently of the MM (typically
explicitly using flags like PTRACE_MODE_READ_FSCREDS).  Including for
threads that no longer have a VM (and maybe never did, like most kernel
threads).

It's not what this flag was designed for, but it is what it is.

The ptrace code does check that the uid/gid matches, so you do have to
be uid-0 to see kernel thread details, but this means that the
traditional "drop capabilities" model doesn't make any difference for
this all.

Make it all make a *bit* more sense by saying that if you don't have a
MM pointer, we'll use a cached "last dumpability" flag if the thread
ever had a MM (it will be zero for kernel threads since it is never
set), and require a proper CAP_SYS_PTRACE capability to override.

552cc2306c macsec: use rcu_work to defer TX SA crypto cleanup out of softirq
free_txsa() is an RCU callback running in softirq context, but calls
crypto_free_aead() which can invoke vunmap() internally on hardware
crypto drivers (e.g. hisi_sec2), triggering a kernel crash.

Use rcu_work to defer the cleanup to a workqueue, for the same reasons
as the analogous fix to free_rxsa() in the previous patch.

6624bba469 macsec: use rcu_work to defer RX SA crypto cleanup out of softirq
crypto_free_aead() can internally invoke vunmap() (e.g. via
dma_free_attrs() in hardware crypto drivers such as hisi_sec2).
vunmap() must not be called from softirq context, but free_rxsa()
is an RCU callback that runs in softirq, leading to a kernel crash:

  vunmap+0x4c/0x70
  __iommu_dma_free+0xd0/0x138
  dma_free_attrs+0xf4/0x100
  sec_aead_exit+0x64/0xb8 [hisi_sec2]
  crypto_destroy_tfm+0x98/0x110
  free_rxsa+0x28/0x50 [macsec]
  rcu_do_batch+0x184/0x460
  rcu_core+0xf4/0x1f8
  handle_softirqs+0x118/0x330

Use rcu_work to defer the cleanup to a workqueue. rcu_work dispatches
the worker asynchronously after the RCU grace period, so no thread
blocks waiting, and concurrent releases of multiple SAs naturally
share the same grace period.

59a62ea458 sched_ext: Fixes for v7.1-rc3
Bulk is hardening of the new sub-scheduler infrastructure.
 
 - UAFs and lifecycle bugs on the sub-sched attach/detach paths: parent
   sub_kset freed under a racing child, list_del_rcu on an uninitialized
   list head, ops->priv stomped by concurrent attach/detach, and a UAF in
   the init-failure error path.
 
 - Task state-machine reorg closing concurrent enable-vs-dead races: a
   task exiting during the unlocked init window could trip NULL ops
   derefs or skip exit_task() cleanup.
 
 - A scx_link_sched() self-deadlock on scx_sched_lock.
 
 - isolcpus: stop dereferencing the now-RCU-protected HK_TYPE_DOMAIN
   cpumask without RCU, and stop rejecting BPF schedulers when only
   cpuset isolated partitions are active.
 
 - PREEMPT_RT: disable irq_work runs in hardirq context so dumps show the
   failing task rather than the irq_work kthread.
 
 - Assorted !CONFIG_EXT_SUB_SCHED, randconfig, and selftest build fixes.

df733ddc26 vfio/pci: Make VFIO_PCI_OFFSET_TO_INDEX() return unsigned
VFIO_PCI_OFFSET_TO_INDEX() is used in several places with a signed
parameter (e.g. loff_t).  Because it makes no sense for a BAR/resource
index to be negative, enforce this in the macro.

This fixes at least one current issue, where vfio_pci_ioeventfd() uses
this macro with an unvalidated signed loff_t returned into a signed
type, leading to a possible negative array access.  This instance does
test against an out-of-bounds positive value, so treating the index as
unsigned fixes this issue.

better decision whether we should plaining reject the buffer (buffer
overflow attempt) or if we can safely memset it to 0 and pass it to the
rest of the stack.

11f152c0ac xen/arm: Replace __ASSEMBLY__ with __ASSEMBLER__ in interface.h
While the GCC and Clang compilers already define __ASSEMBLER__
automatically when compiling assembly code, __ASSEMBLY__ is a
macro that only gets defined by the Makefiles in the kernel.
This can be very confusing when switching between userspace
and kernelspace coding, or when dealing with uapi headers that
rather should use __ASSEMBLER__ instead. So let's standardize now
on the __ASSEMBLER__ macro that is provided by the compilers.

5dd74441cb cgroup/cpuset: Reserve DL bandwidth only for root-domain moves
cpuset_can_attach() currently adds the bandwidth of all migrating
SCHED_DEADLINE tasks to sum_migrate_dl_bw. If the source and destination
cpuset effective CPU masks do not overlap, the whole sum is then
reserved in the destination root domain.

set_cpus_allowed_dl(), however, subtracts bandwidth from the source
root domain only when the affinity change really moves the task between
root domains. A DL task can move between cpusets that are still in the
same root domain, so including that task in sum_migrate_dl_bw can reserve
destination bandwidth without a matching source-side subtraction.

Share the root-domain move test with set_cpus_allowed_dl(). Keep
nr_migrate_dl_tasks counting all migrating deadline tasks for cpuset DL
task accounting, but add to sum_migrate_dl_bw only for tasks that need a
root-domain bandwidth move. Keep using the destination cpuset effective
CPU mask and leave the broader can_attach()/attach() transaction model
unchanged.

dec85d2fbd irqchip/gic-v5: Move LPI allocation into the LPI domain
The IPI and ITS MSI domains currently allocate and release LPIs
directly, then pass the selected LPI ID to the parent LPI domain. This
leaks the LPI domain's allocation policy into its child domains and
forces each child to duplicate part of the parent domain's teardown.

Make the LPI domain allocate LPIs in its .alloc() callback and release
them in a matching .free() callback. Child domains can then request a
parent interrupt without passing an implementation-specific LPI ID,
and the LPI lifetime is tied to the domain that owns the LPI
namespace.

Remove the gicv5_alloc_lpi() and gicv5_free_lpi() wrappers now that no
external caller needs to manage LPIs directly.

This is a preparatory change for an actual leakage problem in the
allocation code and therefore tagged with the same Fixes tag.

657b594b20 fprobe: Fix unregister_fprobe() to wait for RCU grace period
Commit 4346ba1604 ("fprobe: Rewrite fprobe on function-graph tracer")
changed fprobe to register struct fprobe to an rcu-hlist, but it forgot
to wait for RCU GP. Thus there can be use-after-free if the fprobe is
released right after unregistering. This can be happened on fprobe
event and sample module code.

To fix this issue, add synchronize_rcu() in unregister_fprobe().

Note that BPF is OK because fprobe is used as a part of
bpf_kprobe_multi_link. This unregisters its fprobe in
bpf_kprobe_multi_link_release() and it is deallocated via
bpf_kprobe_multi_link_dealloc(), which is invoked from
bpf_link_defer_dealloc_rcu_gp() RCU callback.

For BPF, this also introduced unregister_fprobe_async() which does
NOT wait for RCU grace priod.

c941d7391f sched_ext: Close root-enable vs sched_ext_dead() race with SCX_TASK_INIT_BEGIN
scx_root_enable_workfn() drops the iter rq lock for ops.init_task() and a
TASK_DEAD @p can fall through sched_ext_dead() in that window. The race hits
when sched_ext_dead() observes SCX_TASK_INIT (the intermediate state before
@p->scx.sched is published) and dereferences NULL via SCX_HAS_OP(NULL,
exit_task), or observes SCX_TASK_NONE during the unlocked init window and
skips cleanup so exit_task() never runs.

Add SCX_TASK_INIT_BEGIN. The enable path writes NONE -> INIT_BEGIN under the
iter rq lock, then takes the rq lock again after init to walk INIT_BEGIN ->
INIT -> READY. sched_ext_dead() that wins the rq-lock race observes
INIT_BEGIN and sets DEAD without calling into ops; the post-init recheck
unwinds via scx_sub_init_cancel_task().

scx_fork() runs single-threaded against sched_ext_dead() (the task is not on
scx_tasks until scx_post_fork() adds it) so its INIT_BEGIN -> INIT walk
needs no rq-lock pairing; it rolls back to NONE on ops.init_task() failure.

The validation matrix grows the INIT_BEGIN row and the INIT_BEGIN -> DEAD
edge; INIT now requires INIT_BEGIN as the predecessor. scx_sub_disable()'s
migration writes INIT_BEGIN as a synthetic predecessor to satisfy the
tightened verification.

The sub-sched paths still race with sched_ext_dead() during the unlocked
init window. This will be fixed by the next patch.

cceb8fa9cb sched_ext: Replace SCX_TASK_OFF_TASKS flag with SCX_TASK_DEAD state
SCX_TASK_OFF_TASKS marked tasks already through sched_ext_dead() so cgroup
task iteration would skip them. This can be expressed better with a task
state. Replace the flag with SCX_TASK_DEAD.

scx_disable_and_exit_task() resets state to NONE on its way out, so
sched_ext_dead() now sets DEAD after the wrapper returns. The validation
matrix grows NONE -> DEAD, warns on DEAD -> NONE, and tightens READY's
predecessor to INIT or ENABLED so the new DEAD value cannot silently
transition to READY.

Prepares for the following enable vs dead race fix.

====================
Netfilter fixes for net

The following batch contains Netfilter fixes for net:

1) Allow initial x_tables table replacement without emitting an audit
   log message. Delay the register message until after hooks are wired up
   to avoid unnecessary unregister logs during error unwinding.

2) Fix a NULL dereference by allocating hook ops before adding the
   table to the per-netns list. Use `synchronize_rcu()` during error
   unwinding to ensure the table stops processing packets before
   teardown. Defer audit log register message until all operations
   succeed.

3) Refactor xtables to use a single `xt_unregister_table_pre_exit`
   function. Eliminate code duplication by centralizing table
   unregistration logic within the xtables core. ebtables cannot be
   changed due to incompatibility.

4) Unregister xtables templates before module removal. This prevents
   a race condition where userspace instantiates a new table after the
   pernet unreg removed the current table.

5) Add `xtables_unregister_table_exit` to fully unregister netfilter
   tables during module removal. Unlink the table from dying lists,
   then free hook operations.

6) Implement a two-stage removal scheme for ebtables following the
   x_tables pattern. Assign table->ops while holding the ebt mutex to
   prevent exposing partially-filled structures.

7) Fix ebtables module initialization race. Register the template last
   in table initialization functions. Prevent table instantiation before
   pernet operations are available.

8) Fix a race condition in x_tables module initialization. Ensure
   pernet ops are fully set up before exposing the table to userspace.

9) Fix a race condition in ebtables module initialization, similar to
   previous patch.

10) Restore propagation of helper to expected connection, this is a
    fix-for-recent-fix.

11) Validate that the expectation tuple and mask netlink attributes are
    present when adding expectation via nfqueue, this fixes a possible
    null-ptr-deref.

12) Fix possible rare memleak in the SIP helper in case helper has been
    detached from conntrack entry, from Li Xiasong.

13) Fix refcount leak in nft_ct when creating custom expectation, also
    from Li Xiason.

Patches 1-9 from Florian Westphal.

10) Restore propagation of helper to expected connection, this is a
    fix-for-recent-fix.

11) Check that tuple and mask netlink attributes are set when creating an
    expectation via nfqueue.

efda25ee84 genetlink: free the skb on 'group >= family->n_mcgrps'
These methods generally consume ownership of the provided skb, so even
if an error path is encountered, the skb is freed. This is because the
very first thing they do after some initial setup is to unconditionally
consume the skb via consume_skb(skb). Any subsequent errors lead to the
core netlink layer freeing the skb.

However, there is one check that occurs before ownership is passed,
which is the check for the group index. So if this error condition is
encountered, then the skb is leaked. This error condition is generally
considered a violation of the netlink API, so it's not expected to occur
under normal circumstances. For the same reason, no callers check for
this error condition, and no callers need to be adjusted. However, we
should still follow the same ownership semantics of the rest of the
function. Thus, free the skb in this codepath.

f2ab4fd027 net: nsh: fix incorrect header length macros
NSH header length is a 6-bit field that encodes the total length of
the header in 4-byte words.  So the maximum length is 0b111111 * 4,
which is 252 and not 256.  The maximum context length is the same
number minus the length of the base header (8), so 244.

These macros are used to validate push_nsh() action in openvswitch.
Miscalculation here doesn't cause any real issues.  In the worst case
the oversized context is truncated while building the header, so we'll
construct and send a broken packet, which is not a big problem, as any
receiver should validate the fields.  No invalid memory accesses will
happen during the header push.  But we should fix the macros to reject
the incorrect actions in the first place.

Using previously defined values and calculating the length instead
of defining numbers directly, so it's easier to understand where they
come from and harder to make a mistake.

e68eadffb7 ipv6: flowlabel: enforce per-netns limit for unprivileged callers
fl_size, fl_ht and ip6_fl_lock in net/ipv6/ip6_flowlabel.c are
file scope and shared across netns. mem_check() reads fl_size to
decide whether to deny non-CAP_NET_ADMIN callers. capable() runs
against init_user_ns, so an unprivileged user in any non-init
userns can push fl_size past FL_MAX_SIZE - FL_MAX_SIZE / 4 and
starve every other unprivileged userns on the host.

Add struct netns_ipv6::flowlabel_count, bumped and decremented
next to fl_size in fl_intern, ip6_fl_gc and ip6_fl_purge. The new
field fills the existing 4-byte hole after ipmr_seq, so struct
netns_ipv6 stays the same size on 64-bit builds.

Bump FL_MAX_SIZE from 4096 to 8192. It has been 4096 since the
file was added. Machines and connection counts have grown.

mem_check() folds an extra per-netns ceiling into the existing
non-CAP_NET_ADMIN conditional. The ceiling is half of the total
budget that unprivileged callers have ever been able to use, i.e.
(FL_MAX_SIZE - FL_MAX_SIZE / 4) / 2 = 3072 entries. With
FL_MAX_SIZE doubled, this preserves the original per-user reach
of 3K (what an unprivileged caller could already obtain before
this change), while forcing an attacker to spread allocations
across at least two netns to exhaust the global non-CAP_NET_ADMIN
budget.

CAP_NET_ADMIN against init_user_ns still bypasses both caps.

The previous patch took ip6_fl_lock across mem_check and
fl_intern, so the new flowlabel_count read in mem_check and the
new flowlabel_count++ in fl_intern run under the same critical
section. flowlabel_count is therefore plain int, like fl_size.

b2ed01e7ad drm/ttm: Fix ttm_bo_swapout() infinite LRU walk on swapout failure
When ttm_tt_swapout() fails, the current code calls
ttm_resource_add_bulk_move() followed by ttm_resource_move_to_lru_tail()
to restore the resource's bulk_move membership.

However, ttm_resource_move_to_lru_tail() places the resource at the tail
of the LRU list which, relative to the walk cursor's hitch node (placed
immediately after the resource when it was yielded), puts the resource
*in front of the* the hitch. The next list_for_each_entry_continue() from
the hitch finds the same resource again, causing an infinite loop.

Fix by deferring del_bulk_move to the success path only.

On the success path, TTM_TT_FLAG_SWAPPED has just been set by
ttm_tt_swapout() but the resource is still tracked in the bulk_move range,
so ttm_resource_del_bulk_move()'s !ttm_resource_unevictable() guard would
incorrectly skip the removal. Introduce
ttm_resource_del_bulk_move_unevictable() which bypasses that guard.

411c1cf430 arm64/entry: Fix arm64-specific rseq brokenness
Mathias Stearn reports that since v6.19, there are two big issues
affecting rseq:

(1) On arm64 specifically, rseq critical sections aren't aborted when
    they should be.

(2) The 'cpu_id_start' field is no longer written by the kernel in all
    cases it used to be, including some cases where TCMalloc depends on
    the kernel clobbering the field.

This patch fixes issue #1. This patch DOES NOT fix issue #2, which will
need to be addressed by other patches.

The arm64-specific brokenness is a result of commits:

  2fc0e4b412 ("rseq: Record interrupt from user space")
  39a167560a ("rseq: Optimize event setting")

The first commit failed to add a call to rseq_note_user_irq_entry() on
arm64. Thus arm64 never sets rseq_event::user_irq to record that it may
be necessary to abort an active rseq critical section upon return to
userspace. On its own, this commit had no functional impact as the value
of rseq_event::user_irq was not consumed.

The second commit relied upon rseq_event::user_irq to determine whether
or not to bother to perform rseq work when returning to userspace. As
rseq_event::user_irq wasn't set on arm64, this work would be skipped,
and consequently an active rseq critical section would not be aborted.

Fix this by giving arm64 syscall-specific entry/exit paths, and
performing the relevant logic in syscall and non-syscall paths,
including calling rseq_note_user_irq_entry() for non-syscall entry.

Currently arm64 cannot use syscall_enter_from_user_mode(),
syscall_exit_to_user_mode(), and irqentry_exit_to_user_mode(), due to
ordering constraints with exception masking, and risk of ABI breakage
for syscall tracing/audit/etc. For the moment the entry/exit logic is
left as arm64-specific, directly using enter_from_user_mode() and
exit_to_user_mode(), but mirroring the generic code.

I intend to follow up with refactoring/cleanup, as we did for kernel
mode entry paths in commit:

  041aa7a853 ("entry: Split preemption from irqentry_exit_to_kernel_mode()")

... which will allow arm64 to use the GENERIC_IRQ_ENTRY functions directly.

307abfac04 kprobes: skip non-symbol addresses in kprobe_add_ksym_blacklist()
When kprobe_add_area_blacklist() iterates through a section like
.kprobes.text, the start address may not correspond to a named symbol.
On ARM64 with CONFIG_DYNAMIC_FTRACE_WITH_CALL_OPS=y (introduced by
commit baaf553d3b ("arm64: Implement
HAVE_DYNAMIC_FTRACE_WITH_CALL_OPS")), the compiler flag
-fpatchable-function-entry=4,2 inserts 2 NOPs before each function entry
point for ftrace call_ops. These pre-function NOPs sit at the section base
address, before the first named function symbol. The compiler emits a $x
mapping symbol at offset 0x00 to mark the start of code, but
find_kallsyms_symbol() ignores mapping symbols.

Without CONFIG_DYNAMIC_FTRACE_WITH_CALL_OPS (e.g. defconfig), no
pre-function NOPs are inserted, the first function starts at offset
0x00, and the bug does not trigger.

This only affects modules that have a .kprobes.text section (i.e. those
using the __kprobes annotation). Modules using NOKPROBE_SYMBOL() instead
(like kretprobe_example.ko) blacklist exact function addresses via the
_kprobe_blacklist section and are not affected.

For kprobe_example.ko on ARM64 with -fpatchable-function-entry=4,2,
the .kprobes.text section layout is:

  offset 0x00: $x + 2 NOPs    (mapping symbol + ftrace preamble)
  offset 0x08: handler_post   (64 bytes)
  offset 0x50: handler_pre    (68 bytes)

kprobe_add_area_blacklist() starts iterating from the section base
address (offset 0x00), which only has the $x mapping symbol.
kprobe_add_ksym_blacklist() then calls kallsyms_lookup_size_offset()
for this address, which goes through:

  kallsyms_lookup_size_offset()
    -> module_address_lookup()
      -> find_kallsyms_symbol()

find_kallsyms_symbol() scans all module symbols to find the closest
preceding symbol.

Since no named text symbol exists at offset 0x00,
find_kallsyms_symbol() picks __UNIQUE_ID_vermagic (a .modinfo symbol
whose address is in the temporary image) as the "best" match. The
computed "size" = next_text_symbol - modinfo_symbol spans across
these two unrelated memory regions, creating a blacklist entry with
a bogus range of tens of terabytes.

Whether this causes a visible failure depends on address randomization,
here is what happens on Raspberry Pi 4/5:

  - On RPi5, the bogus size was ~35 TB. start + size stayed within
    64-bit range, so the blacklist entry covered the entire kernel
    text. register_kprobe() in the module's own init function failed
    with -EINVAL.

  - On RPi4, the bogus size was ~75 TB. start + size overflowed
    64 bits and wrapped to a small address near zero. The range
    check (addr >= start && addr < end) then failed because end
    wrapped around, so the bogus entry was accidentally harmless
    and kprobes worked by luck.

The same bug exists on both machines, but randomization determines whether
the integer overflow masks it or not.

Fix this by adding notrace to the __kprobes macro. Functions in

dcb0f9aefd netfilter: nf_conntrack_expect: restore helper propagation via expectation
A recent series to fix expectations broke helper propagation via
expectation, this mechanism is used by the sip and h323 helper. This
also propagates the conntrack helper to expected connections. I changed
semantics of exp->helper which now tells us the actual helper that
created the expectation.

Add an explicit assign_helper field to expectations for this purpose
and update helpers to use it.

Restore this feature for userspace conntrack helper via ctnetlink
nfqueue integration so it is again possible to attach a helper to an
expectation, where it makes sense. This is not restored via ctnetlink
expectation creation as there is no client for such feature. Use the
expectation layer 4 protocol number for the helper lookup for
consistency.

Make sure the expectation using this helper propagation mechanism also
go away when the helper is unregistered.

b4597d5fd7 netfilter: x_tables: add and use xtables_unregister_table_exit
Previous change added xtables_unregister_table_pre_exit to detach the
table from the packetpath and to unlink it from the active table list.
In case of rmmod, userspace that is doing set/getsockopt for this table
will not be able to re-instantiate the table:
 1. The larval table has been removed already
 2. existing instantiated table is no longer on the xt pernet table list.

This adds the second stage helper:

unlink the table from the dying list, free the hook ops (if any) and do
the audit notification.  It replaces xt_unregister_table().

b62eb8dcf2 netfilter: x_tables: allocate hook ops while under mutex
arp/ip(6)t_register_table() add the table to the per-netns list via
xt_register_table() before allocating the per-netns hook ops copy
via kmemdup_array().  This leaves a window where the table is
visible in the list with ops=NULL.

If the pernet exit happens runs concurrently the pre_exit callback finds
the table via xt_find_table() and passes the NULL ops pointer to
nf_unregister_net_hooks(), causing a NULL dereference:

  general protection fault in nf_unregister_net_hooks+0xbc/0x150
  RIP: nf_unregister_net_hooks (net/netfilter/core.c:613)
  Call Trace:
    ipt_unregister_table_pre_exit
    iptable_mangle_net_pre_exit
    ops_pre_exit_list
    cleanup_net

Fix by moving the ops allocation into the xtables core so the table is
never in the list without valid ops.  Also ensure the table is no longer
processing packets before its torn down on error unwind.
nf_register_net_hooks might have published at least one hook; call
synchronize_rcu() if there was an error.

audit log register message gets deferred until all operations have
passed, this avoids need to emit another ureg message in case of
error unwinding.

Based on earlier patch by Tristan Madani.

c73370c677 btrfs: tracepoints: fix sleep while in atomic context in btrfs_sync_file()
The trace event btrfs_sync_file() is called in an atomic context (all trace
events are) and its call to dput(), which is needed due to the call to
dget_parent(), can sleep, triggering a kernel splat.

This can be reproduced by enabling the trace event and running btrfs/056
from fstests for example. The splat shown in dmesg is the following:

platform/x86: intel: Add notifiers support
In some cases a driver using services of vsec_tpmi driver requires some
processing before vsec_tpmi exits. For example a children using debugfs
can't use debugfs as this will be deleted by the vsec_tpmi driver.

This is the case when unbind using PCI driver interface. In this case
the remove callback of vsec_tpmi driver is called first, then remove
callback of its children.

Add support of blocking chain notifiers support. Notify on successful probe
and before clean up in the remove callback.

91b5a598b5 Bluetooth: l2cap: defer conn param update to avoid conn->lock/hdev->lock inversion
When a BLE peripheral sends an L2CAP Connection Parameter Update Request
the processing path is:

  process_pending_rx()          [takes conn->lock]
    l2cap_le_sig_channel()
      l2cap_conn_param_update_req()
        hci_le_conn_update()    [takes hdev->lock]

Meanwhile other code paths take the locks in the opposite order:

  l2cap_chan_connect()          [takes hdev->lock]
    ...
      mutex_lock(&conn->lock)

  l2cap_conn_ready()            [hdev->lock via hci_cb_list_lock]
    ...
      mutex_lock(&conn->lock)

This is a classic AB/BA deadlock which lockdep reports as a circular
locking dependency when connecting a BLE MIDI keyboard (Carry-On FC-49).

Fix this by making hci_le_conn_update() defer the HCI command through
hci_cmd_sync_queue() so it no longer needs to take hdev->lock in the
caller context.  The sync callback uses __hci_cmd_sync_status_sk() to
wait for the HCI_EV_LE_CONN_UPDATE_COMPLETE event, then updates the
stored connection parameters (hci_conn_params) and notifies userspace
(mgmt_new_conn_param) only after the controller has confirmed the update.

A reference on hci_conn is held via hci_conn_get()/hci_conn_put() for
the lifetime of the queued work to prevent use-after-free, and
hci_conn_valid() is checked before proceeding in case the connection was
removed while the work was pending.  The hci_dev_lock is held across
hci_conn_valid() and all conn field accesses to prevent a concurrent
disconnect from invalidating the connection mid-use.

1f7305d87a KVM: arm64: Work around C1-Pro erratum 4193714 for protected guests
C1-Pro cores with SME have an erratum where TLBI+DSB does not complete
all outstanding SME accesses. Instead a DSB needs to be executed on the
affected CPUs. The implication is that pages cannot be unmapped from the
host Stage 2 and then provided to a protected guest or to the
hypervisor. Host SME accesses may still complete after this point.

This erratum breaks pKVM's guarantees, and the workaround is hard to
implement as EL2 and EL1 share a security state meaning EL1 can mask
IPIs sent by EL2, leading to interrupt blackouts.

Instead, do this in EL3. This has the advantage of a separate security
state, meaning lower EL cannot mask the IPI. It is also simpler for EL3
to know about CPUs that are off or in PSCI's CPU_SUSPEND.

Add the needed hook to host_stage2_set_owner_metadata_locked(). This
covers the cases where the host loses access to a page:

  __pkvm_host_donate_guest()
  __pkvm_guest_unshare_host()
  host_stage2_set_owner_locked() when owner_id == PKVM_ID_HYP

Since pKVM relies on the firmware call for correctness, check for the
firmware counterpart during protected KVM initialisation and fail the
pKVM initialisation if it is missing.

82f572449c rseq: Implement read only ABI enforcement for optimized RSEQ V2 mode
The optimized RSEQ V2 mode requires that user space adheres to the ABI
specification and does not modify the read-only fields cpu_id_start,
cpu_id, node_id and mm_cid behind the kernel's back.

While the kernel does not rely on these fields, the adherence to this is a
fundamental prerequisite to allow multiple entities, e.g. libraries, in an
application to utilize the full potential of RSEQ without stepping on each
other toes.

Validate this adherence on every update of these fields. If the kernel
detects that user space modified the fields, the application is force
terminated.

====================
IPVS fixes for net

The following batch contains IPVS fixes for net to address issues
from the latest net-next pull request.

Julian Anastasov made the following summary:

1-3) Fixes for the recently added resizable hash tables

4) dest from trash can be leaked if ip_vs_start_estimator() fails

5) fixed races and locking for the estimation kthreads

6) fix for wrong roundup_pow_of_two() usage in the resizable hash
   tables

7-8) v2 of the changes from Waiman Long to properly guard against
  the housekeeping_cpumask() updates:

  https://lore.kernel.org/netfilter-devel/20260331165015.2777765-1-longman@redhat.com/

  I added missing Fixes tag. The original description:

  Since commit 041ee6f372 ("kthread: Rely on HK_TYPE_DOMAIN for preferred
  affinity management"), the HK_TYPE_KTHREAD housekeeping cpumask may no
  longer be correct in showing the actual CPU affinity of kthreads that
  have no predefined CPU affinity. As the ipvs networking code is still
  using HK_TYPE_KTHREAD, we need to make HK_TYPE_KTHREAD reflect the
  reality.

  This patch series makes HK_TYPE_KTHREAD an alias of HK_TYPE_DOMAIN
  and uses RCU to protect access to the HK_TYPE_KTHREAD housekeeping
  cpumask.

Julian plans to post a nf-next patch to limit the connections by using
"conn_max" sysctl. With Simon Horman, they agreed that this is an old
problem that we do not have a limit of connections and it is not a
stopper for this patchset.
