bpf_arena_free_pages() accepts scalar arena addresses. The runtime
masks the address to the low 32 bits and reconstructs a full user
address from the arena base before returning the range to the arena
free tree.
When the scalar value is below the low 32 bits of the arena base,
full_uaddr falls below user_vm_start. The existing upper-end clipping
then turns this into an out-of-range free-tree offset. A later
allocation can reuse that offset and return an address below the arena
mapping.
Reject such frees before computing the clipped range.

====================
bpf: Add memory usage for arena and selftest
arena is the only map type whose map_mem_usage() still returns 0, so
bpftool and fdinfo always show 0 memlock for it no matter how many pages
it holds. This series adds the accounting, runs the arena selftests
serially so they don't OOM a small CI VM, and adds a test for it.
v1 -> v2:
- split the scratch_page -> arena refactor into a prep patch (no
functional change)
- use WRITE_ONCE() for nr_pages to pair with the lockless reader
- reword the "run serially" commit message
- selftest: alloc prog returns 0 so the failure check is reached

Every arena reserves a 4GB kernel vmalloc region at creation, and on a
KASAN build that eagerly populates ~512MB of shadow memory per arena. When
several arena tests run in parallel their shadow adds up, exhausts the
memory of a small CI VM and trips the OOM killer during map creation.
Make the dedicated arena tests (arena_* and libarena*) serial so they no
longer pile up in the parallel phase. That alone brings the peak number of
live arenas back within the CI memory budget.
A few other tests such as verifier_arena*, stream and compute_live_registers
create an arena too, but they run inside shared RUN_TESTS()/RUN() suites, so
turning them serial would drag many unrelated subtests along with them.
Leave those as-is.

arena is the only map type whose map_mem_usage() still returns 0, so
"bpftool map show" and fdinfo always showed 0 memlock for an arena no

Count the pages that are actually mapped into the arena: bump a counter in
apply_range_set_cb() when a page goes in and drop it in
apply_range_clear_cb() when a page goes out, both under the arena spinlock.
map_mem_usage() then just returns nr_pages << PAGE_SHIFT.
Only real data pages are counted, not the scratch page.

check_kfunc_call() reads meta.func_name when bpf_fetch_kfunc_arg_meta()
returns -EACCES, but that error can come from fetch_kfunc_meta() (e.g.
fd_array_get_btf() rejecting BTF binding for a signed program) before
meta is memset(), leaving it uninitialized and risking a garbage deref
in verbose().
Move the memset() to the start of bpf_fetch_kfunc_arg_meta() so meta is
zeroed on every error return. The intended "not allowed" -EACCES path
still sets func_name first, so its message is unchanged.

For a bloom filter, the value argument of bpf_map_peek_elem() is always
an input. Therefore, the verifier should not allow passing uninitialized
stack memory to it to avoid information leak.
bpf_map_peek_elem() tags its value argument ARG_PTR_TO_MAP_VALUE |
MEM_UNINIT, telling the verifier the callee fills the buffer. This holds
for queue/stack maps, but not for a bloom filter, which reads the buffer
as an input to test set membership and never writes it.
As a result, a program can pass an uninitialized stack buffer to
bpf_map_peek_elem() on a bloom filter. The verifier accepts it and marks
the buffer initialized on return, letting the program read back leftover
kernel stack memory. Bloom maps require CAP_BPF to create, so this is a
CAP_BPF-gated stack infoleak that bypasses the boundary CAP_BPF is meant
to enforce (arbitrary kernel reads are gated behind CAP_PERFMON).

bnxt_aux_devices_init() calls auxiliary_device_init() before all fields
used by bnxt_aux_dev_release() are initialized. After
auxiliary_device_init() succeeds, later errors must unwind with
auxiliary_device_uninit(), which invokes the release callback.
The release callback assumes that aux_priv->id, aux_priv->edev,
edev->net and edev->ulp_tbl are all populated. If allocation fails
after auxiliary_device_init(), the release path can otherwise dereference
or clear partially initialized state.
Allocate and attach the bnxt_en_dev and ULP table before calling
auxiliary_device_init(), so the release callback only sees a fully
initialized auxiliary private object. If auxiliary_device_init() itself
fails, free those allocations directly because device_initialize() has not
run and the release callback will not be invoked.
This issue was found by a static analysis checker and confirmed by manual

The auth_hmacs array in struct sctp_cookie is supposed to store a complete
SCTP_AUTH_HMAC_ALGO parameter, which consists of a struct sctp_paramhdr
followed by N HMAC identifiers.
However, the array size was calculated using an extra 2 bytes instead of
sizeof(struct sctp_paramhdr), which is 4 bytes. When four HMAC identifiers
are configured, the HMAC-ALGO parameter stored in the endpoint is larger
than the auth_hmacs buffer in the cookie.
As a result, sctp_association_init() copies beyond the end of auth_hmacs
when initializing the association, corrupting the adjacent auth_chunks
field. This can lead to an invalid HMAC identifier being accepted and later
cause an out-of-bounds read in sctp_auth_get_hmac().
Fix the array size calculation by including the full SCTP parameter header
size.

When a dpll_pin is shared across multiple dpll_device instances and
those devices are being unregistered (e.g. during driver module removal),
a NULL pointer dereference can occur in dpll_msg_add_pin_ref_sync().
This happens under the following conditions:
- A pin is registered with two or more dpll devices (dpll_A, dpll_B)
- The pin has ref_sync pairs with other pins
- During unregistration of dpll_A's pins, a ref_sync partner pin is
unregistered first, removing it from dpll_A->pin_refs
- But since the partner pin is still registered with dpll_B, its
dpll_refs is not empty, so dpll_pin_ref_sync_pair_del() does NOT
run and the partner stays in the pin's ref_sync_pins xarray
- When the pin itself is then unregistered from dpll_A, the delete
notification calls dpll_msg_add_pin_ref_sync() which finds the
partner in ref_sync_pins, passes dpll_pin_available() (partner is
still registered with dpll_B), but dpll_pin_on_dpll_priv(dpll_A,
partner) returns NULL because partner was already removed from
dpll_A->pin_refs
- The NULL priv pointer is passed to the driver's ref_sync_get
callback, which dereferences it

====================
netfilter: updates for net
The following patchset contains Netfilter fixes for *net*.
These are fixes for bugs except patches 6 and 9 which fix issues added in
last PR and 7.1-rc1.
1) Reject unsupported target families in xt_nat_checkentry().
From Wyatt Feng.
2) Fix inverted time_after() check in ecache_work_evict_list().
Causes pointless work rescheds and thus way longer time to
clear the pending event backlog. From Yizhou Zhao.
3) Fix a use-after-free in br_ip6_fragment() caused by a dangling prevhdr
pointer. From Xiang Mei.
4) Fix incorrect conntrack zone comparison in nf_conncount tuple
deduplication. Pass IP_CT_DIR_ORIGINAL, not zone direction.
From Yizhou Zhao.
5) Add bridge tunnel flowtable regression test for a bug that
got fixed in the previous PR. From Zhengyang Chen.
6) Use the correct direction when setting up tunnel routes in the flowtable
xmit path. From Pablo Neira Ayuso. This fixes a bug added in the
previous PR.
7) Reload IP header after potential skb head reallocation in IPVS.
8) Fix incorrect IPv6 transport offsets in TCP application code. Correct the
ICMPv6 header offset to ensure proper checksumming with extension headers,
from Julian Anastasov. this is a followup to the previous PR.
9) Remove null-termination requirement for xt_physdev masks, this broke
device names with 15 characters.

Some JIT compilers, such as x86_64, rely on a register to pass the TCC.
When subprograms of synchronous callback invoke tailcall, C helpers
invoking bpf callback clobber this register, and the corrupted TCC may
bypass the TCC limit, leading to infinite tailcall.
Fix this by rejecting tailcall inside all subprogs of sync callback.
This also cleanly consolidates the existing async and exception callback
checks into a single unified `is_cb` check.

Currently in check_max_stack_depth_subprog, when the verifier enters a
new callee branch, the local tail_call_reachable is not properly
synchronized with the callee's state.
Consider a main prog branching into multiple subprogs:
subprog0 -> tailcall
main <
subprog1 -> subprog2
When the verifier finishes checking subprog0 and backtracks to main
prog, the local tail_call_reachable state is left as true. As it
proceeds to subprog1, this uncleared state leaks into the new branch,
falsely marking subprog1 and subprog2 as tailcall reachable.
Fix this by explicitly syncing tail_call_reachable with the callee's
has_tail_call state on entry. The caller's state is safely preserved and
restored via the existing backtracking logic.

====================
bpf: Fix tracing of kfuncs with implicit args
Tejun reported an issue where a BPF program tracing a kfunc with
KF_IMPLICIT_ARGS can crash the kernel [1]. This is caused by a bug in
bpf_check_attach_target(): the btf_func_model for such a kfunc is
computed from a wrong BTF prototype. For more details see the commit
message of patch #1.
The second patch adds a selftest that can catch this situation.
The fix is a candidate for 7.1 backport.

v2->v3:
* Replace btf_kfunc_accumulated_flags() with btf_kfunc_check_flag()
following a discussion with Eduard. Inlining the hook walk is a
worse option than a helper, because BTF_KFUNC_HOOK_MAX and co are
internal to btf.c and exposing them is uglier.
* remove reduntant btf_is_func check (Jiri)

KF_IMPLICIT_ARGS kfuncs have a BPF-call prototype and a real kernel
target prototype. Add a tracing selftest that attaches fentry and fexit
programs to bpf_kfunc_implicit_arg(), runs a syscall BPF program that
calls it, and checks that the tracing context exposes both the explicit
argument and the implicit prog aux pointer.

A kfunc marked with KF_IMPLICIT_ARGS flag takes implicit arguments
(such as bpf_prog_aux) that the verifier injects at load time.
resolve_btfids strips those from the kfunc's BTF-visible prototype and
keeps the real kernel ABI in a counterpart _impl prototype [1].
fentry/fexit/fmod_ret/fsession programs may attach to the BPF kernel
functions, including those with implicit args. However
bpf_check_attach_target() and bpf_check_attach_btf_id_multi() extract
the struct btf_func_model from the wrong BTF prototype of the
kfunc. The btf_func_model is later read to construct the trampoline,
which then causes the injected implicit argument to be clobbered and
the kfunc dereferencing garbage.
Add btf_attach_func_proto() to resolve the real ABI prototype of the
kfunc the way the call site does: by looking up the _impl prototype
for a KF_IMPLICIT_ARGS kfunc. Use it at both attach-target model
construction sites.
To enable this, make two supporting changes:
* pass bpf_verifier_log instead of bpf_verifier_env to
find_kfunc_impl_proto(), so it can be reused from the attach path
* add btf_kfunc_check_flag() to test a flag across all of a kfunc's
hook sets, because a program attaching to a kfunc is not in the
kfunc's call-set
KF_IMPLICIT_ARGS must be consistent across the sets, so
btf_kfunc_check_flag() returns -EINVAL on inconsistency.
btf_kfunc_check_flag() reads the kfunc's flags from the target's
kfunc_set_tab. For a module BTF that table is stable only after the
module is live, so take a module reference around the read, mirroring
how the kfunc call path gates the same lookup with btf_try_get_module().
The remaining call sites of btf_distill_func_proto() are safe as
is. The BPF_TRACE_ITER case distills a registered iterator's
prototype, and bpf_struct_ops_desc_init() distills the
function-pointer members of a struct_ops type. Neither is a kfunc, and
so can't have implicit arguments.

The TX state machine (so->tx.state) is driven from three contexts:
sendmsg() claiming and progressing a transfer, the RX path consuming
Flow Control/echo frames, and two hrtimers timing out a stalled
transfer. Mixing a lock-free cmpxchg() claim in sendmsg() with
hrtimer_cancel() calls made under so->rx_lock elsewhere left windows
where a frame or timer callback could act on a state that had already
moved on, corrupting an unrelated transfer.
so->rx_lock now covers the full lifecycle of a TX claim: sendmsg()
takes it to check so->tx.state is ISOTP_IDLE, switch it to
ISOTP_SENDING, bump so->tx_gen and drain the previous transfer's
timers - all as one critical section. isotp_rcv_fc()/isotp_rcv_cf()
already run under this lock via isotp_rcv(), and isotp_rcv_echo() now
takes it itself, so none of them can ever observe a transfer mid-claim.
This also means a transfer can no longer be handed to sendmsg()'s
cleanup paths (signal or send error) while another thread is
concurrently claiming or finishing it, so those paths can cancel
timers and reset the state unconditionally.
isotp_release() claims the socket the same way, so a racing sendmsg()
sees a consistent ISOTP_SHUTDOWN and skips arming its timer or sending.
Only the hrtimer callbacks stay outside so->rx_lock, since they run
under so->rx_lock's cancellation elsewhere and taking it themselves
would deadlock. so->tx_gen lets them recognize whether the transfer
they timed out is still the one currently active, so they don't
report an error against a transfer that has since completed or been
superseded.

isotp_release() looked up the bound network device via dev_get_by_index()
using the stored ifindex. During device unregistration the device is
unlisted from the ifindex hash before the NETDEV_UNREGISTER notifier
chain runs, so a concurrent isotp_release() could find no device, skip
can_rx_unregister() entirely, and still proceed to free the socket.
Since isotp_release() had already removed itself from the isotp
notifier list at that point, isotp_notify() would never get a chance to
clean up either, leaving a stale CAN filter that keeps pointing at the
freed socket.
Fix this the same way raw.c already does: hold a tracked reference to
the bound net_device in the socket (so->dev/so->dev_tracker) from
bind() onward instead of re-resolving it from the ifindex, and
serialize bind()/release() with rtnl_lock() so that so->dev is always
consistent with what the NETDEV_UNREGISTER notifier sees. so->dev
stays valid regardless of ifindex-hash unlisting, and is only ever
cleared by whichever of isotp_release()/isotp_notify() gets there
first, so the filter is always removed exactly once.
isotp_bind() now rejects a (re)bind with -EAGAIN while so->[tx|rx].state
isn't ISOTP_IDLE yet, so a timer left running by a prior
NETDEV_UNREGISTER can't act on a newly bound so->ifindex. Both checks
share the same lock_sock() section, so there is no window in which a
concurrent isotp_notify() clearing so->bound could be missed.
