arm64: kprobes: Allow reentering kprobes while single-stepping
A kprobe can be hit while another kprobe is in KPROBE_HIT_SS state. This
can happen when tracing or perf code runs from the debug exception path
while the first kprobe is preparing or executing its out-of-line
single-step instruction.
Currently arm64 treats a kprobe hit in KPROBE_HIT_SS as unrecoverable,
the same as a hit in KPROBE_REENTER. This is too strict. A hit in
KPROBE_HIT_SS is still a one-level reentry and can be handled by saving
the current kprobe state and setting up single-step for the new probe,
just like reentry from KPROBE_HIT_ACTIVE or KPROBE_HIT_SSDONE.
The truly unrecoverable case is hitting another kprobe while already in
KPROBE_REENTER, because the reentry save area has already been consumed.
Move KPROBE_HIT_SS to the recoverable reentry cases and leave
KPROBE_REENTER as the unrecoverable nested reentry case.
This change also requires saving saved_irqflag in struct prev_kprobe.
When a nested kprobe calls kprobes_save_local_irqflag(), it overwrites
kcb->saved_irqflag with the currently masked DAIF value, losing the
outer kprobe's original DAIF state. Without this fix, when the outer
kprobe's single-step finishes, kprobes_restore_local_irqflag() applies
the wrong DAIF mask and leaves interrupts permanently disabled.
Extend struct prev_kprobe with a saved_irqflag field and save/restore it
alongside kp and status. This ensures the outer kprobe's original
interrupt state is preserved across reentry.
This mirrors the x86 fix in commit

arm64: kprobes: Only handle faults originating from XOL slot
kprobe_fault_handler() currently treats any page fault taken while in
KPROBE_HIT_SS or KPROBE_REENTER state as a kprobe single-step fault. This
assumption does not hold: perf or tracing code may run from the debug
exception path during the single-step window and take its own page fault.
When the fault is handled as a kprobe fault, the PC is rewritten to the
probe address, corrupting the exception recovery context for the real
fault. A typical reproducer is running perf with preemptirq tracepoints
and dwarf callchains while a kprobe is installed on a frequently
executed function.
Fix this in two layers:
1. At function entry, bail out immediately for simulated kprobes
(ainsn.xol_insn == NULL), since they have no XOL slot and any fault
taken during their execution cannot be a single-step fault.
2. For kprobes with an XOL slot, only handle the fault when the
faulting PC matches the XOL instruction address. Faults from any
other PC are left to the normal page fault handler.
This follows the same principle as the x86 fix in commit

mmio_guard_ioremap_hook() attempts to handle unaligned addresses and

io_uring/bpf-ops: reject re-registration of an already-bound ops
io_install_bpf() only rejects a second registration on the ctx side
(ctx->bpf_ops) and sets the per-map back-pointer ops->priv
unconditionally. The struct_ops link path never advances a map past
BPF_STRUCT_OPS_STATE_READY, so the same io_uring_bpf_ops map can be
registered more than once, and bpf_io_reg() re-resolves the target ring
via fget(ops->ring_fd) on every call. A caller can therefore point the
same ring_fd at a different io_ring_ctx between two BPF_LINK_CREATE
calls.
The second registration passes the ctx->bpf_ops check (the new ctx has
none) and overwrites ops->priv, orphaning the first ctx. Teardown
(io_eject_bpf()/bpf_io_unreg()) only reaches a ctx through ops->priv, so
the orphaned ctx is never torn down: its ctx->loop_step keeps pointing
into the struct_ops trampoline, which is freed once the map is gone. A
later io_uring_enter() on the orphaned ring then calls the dangling
ctx->loop_step from io_run_loop() -- a use-after-free of freed
executable memory, reachable by a task with CAP_BPF + CAP_PERFMON.
Reject registration when ops->priv is already set, as hid_bpf_reg()
does for its struct_ops.

drm/ttm/pool: back up at native page order
ttm_pool_split_for_swap() unconditionally splits high-order pool pages
into order-0 pages before backup, so every compound the shrinker
touches is shattered even when the rest of the system would prefer it
stay intact. Under sustained kswapd pressure this fragments memory
enough to drive other parts of MM into recovery loops.
Back up each compound at its native order instead. In
ttm_pool_backup(), hand the full compound to the new
ttm_backup_backup_folio(), which backs up subpages to a contiguous
range of shmem indices and returns the base handle plus the number of
subpages actually backed up (@nr_backed). On full success, free the
compound once at its native order -- no split_page(), no per-4K
refcount juggling.
A per-folio backup can't be made fully atomic under memory pressure:
ttm_backup_backup_folio() must allocate shmem folios before source
subpages can be released, so under true OOM any subpage may fail
while the rest of the compound is still live. Two mechanisms handle
this without regressing reclaim behaviour:
- alloc_gfp gets __GFP_NOMEMALLOC whenever order > 0 (cleared again
for order-0), so a high-order backup fails fast with -ENOMEM
instead of draining kernel reserves, leaving them for other
allocations under the same pressure.
- If ttm_backup_backup_folio() still returns a short @nr_backed with
a valid handle for the successfully-backed prefix, split the
source compound with ttm_pool_split_for_swap(), free the prefix as
order-0 pages (already safely in shmem), and retry the remaining
subpages at order 0, where __GFP_NOMEMALLOC is cleared and
reserves may be used as a last resort.
This preserves the original split-on-OOM fallback while keeping the
common case fragmentation-free, and preserves the "partial backup is
allowed" contract (shrunken is incremented per subpage backed up).
The restore-side leftover-page split in ttm_pool_restore_commit() is
left as-is: it's unreachable in practice and not worth complicating
the restore state machine to avoid.
Testing: the existing backup_fault_inject point only truncated
tt->num_pages, which never exercised the reactive split path above
since it never left a compound partially backed up. Wire fault
injection into ttm_backup_backup_folio() itself: past the first
subpage of a compound, synthesize a -ENOMEM in place of
shmem_read_folio_gfp() when should_fail() trips, producing the same
short @nr_pages_backed a real failure would and forcing
ttm_pool_backup() through the split-and-retry path. The fault_attr
stays private to ttm_pool.c; ttm_backup.c reaches it through
ttm_backup_fault_inject_folio(), declared in ttm_pool_internal.h.
While converting the writeback branch to operate on the whole folio,
the unlock condition after shmem_writeout() also changed from `if
(ret)` to `if (ret == AOP_WRITEPAGE_ACTIVATE)`, matching the actual
contract: shmem_writeout()/swap_writeout() only leave the folio locked
when returning AOP_WRITEPAGE_ACTIVATE; any other return (including a
hard error from arch_prepare_to_swap()) means the folio was already
unlocked internally. The old `if (ret)` check would have double-
unlocked in that hard-error case.

SoC fixes for 7.2
There are only three devicetree fixes this time: one critical memory
corruption fix for Renesas and three minor corrections for Tegra.
The MAINTAINERS file is updated for a new maintainer of the CIX platform
and two address changes.
The rest is all driver fixes, mostly firmware:
- multiple runtime issues in ARM SCMI and FF-A firmware code, dealing
with error handling for corner cases in firmware.
- multiple fixes for reset drivers, dealing with individual platform
specific mistakes and more error handling
- minor build and runtime fixes for the Tegra SoC drivers

drm/appletbdrm: Allocate request/response buffers in begin_fb_access
In atomic_check, damage handling is not fully evaluated. Another atomic_check helper could trigger a full modeset and thus invalidate damage clips. Allocation of the request/response buffers in appletbdrm depends on correct damage information. Otherwise it might allocate incorrectly sized buffers. Allocate the buffers in the driver's begin_fb_access helper.

lockd: fix NLMv3 GRANTED_MSG handling
GRANTED_MSG is a server-to-client callback, so it runs on the client,
where nfsd never registers nlmsvc_ops. The nlm3svc_lookup_host()
helper is for the server-side request handlers
(TEST/LOCK/CANCEL/UNLOCK), which reach nlmsvc_ops->fopen and must
reject requests when nfsd isn't running. GRANTED_MSG only calls
nlmclnt_grant(). Instead, of calling nlm3svc_lookup_host(), which
results in a client failing a GRANTED_MSG call, call
nlmsvc_lookup_host().

misc: nsm: pin the module while the device is open
misc_open() installs a misc driver's file operations with fops_get(),
which pins file_operations::owner before replacing the file's f_op. The
NSM misc device leaves nsm_dev_fops.owner unset, so opening /dev/nsm does
not take a module reference on the nsm driver.
If the driver is built as a module, an open file descriptor can therefore
survive rmmod of the module that provides its ioctl callbacks. A later
ioctl through that descriptor can call into unloaded module text.
Set nsm_dev_fops.owner to THIS_MODULE so the misc core holds the module
while any /dev/nsm file descriptor is open, matching the lifetime
expectation for the installed file operations.

misc: nsm: only unlock nsm_dev on post-lock error paths
nsm_dev_ioctl() jumps to the common out label even when the initial
copy_from_user() fails before nsm->lock has been taken. The error path
then blindly unlocks a mutex that was never acquired.
This issue was found by our static analysis tool and then manually
reviewed against the current tree.
The grounded PoC kept the miscdevice ioctl entry and the pre-lock
copy_from_user(&raw, argp, _IOC_SIZE(cmd)) failure path by issuing
NSM_IOCTL_RAW with an invalid user pointer. That failure reaches the
shared out label before mutex_lock(&nsm->lock). Lockdep reported:
WARNING: bad unlock balance detected!
exploit/193 is trying to release lock (&global_nsm.lock) at:
nsm_dev_ioctl+0x5f/0xcf [vuln_msv]
but there are no more locks to release!
no locks held by exploit/193.
Return immediately on the pre-lock copy_from_user() failure and keep the
common unlock label for the post-lock paths only.

comedi: comedi_parport: deal with premature interrupt
Syzbot reported a general protection fault in
`comedi_get_is_subdevice_running()`, which was called from the interrupt
handler `parport_interrupt()` in the "comedi_parport" driver, but it
does not currently have a C reproducer for the problem. It's
probably due to a premature interrupt for one of two reasons:
1. The driver sets up the interrupt handler before the comedi subdevices
used by the interrupt handler have been allocated, but does not
disable the interrupt in the parallel port's CTRL register first.
2. The driver uses a user-supplied I/O port base address which Syzbot
would have supplied, but it might not be backed by real parallel port
hardware.
Change the initialization order in the driver's comedi "attach" handler
(`parport_attach()`) so that the hardware registers are initialized
before the interrupt handler is requested. This should prevent
premature interrupts occurring for real hardware.
Also add a test to the interrupt handler to ensure the comedi device is
fully attached and return early if it isn't.

uio_hv_generic: Bind to FCopy device by default
The Hyper-V kernel-mode fcopy driver was removed in 6.10 and the new
fcopy daemon requires this uio driver to function. However, by
default the driver does not bind to any devices, and must be
configured through the sysfs "new_id" file.
Since the FCopy device is now only usable through this driver, add its
ID to the driver's ID table so that the daemon will work "out of the
box".

staging: rtl8723bs: fix OOB reads in rtw_get_wps_ie()
rtw_get_wps_ie() iterates over IE data from network frames without
validating that the IE header and payload fit within the remaining
buffer before reading them. Specifically:
- in_ie[cnt + 1] is read without checking cnt + 1 < in_len
- memcmp(&in_ie[cnt + 2], ...) accesses cnt + 2 without bounds check
- in_ie[cnt + 1] is used as length without verifying payload fits
Add bounds checks at the top of the loop body to break early if fewer
than 2 bytes remain for the IE header, or if the declared payload
extends past the end of the buffer. Also require at least 4 bytes of
payload before comparing the WPS OUI.

staging: rtl8723bs: fix inverted HT40 secondary channel offset
rtw_get_chan_type() maps the driver's channel offset to nl80211 channel
types the wrong way around.
In this driver HAL_PRIME_CHNL_OFFSET_LOWER means the primary channel is
the lower 20 MHz half of the 40 MHz pair, i.e. the secondary channel is
above the primary one: rtw_get_center_ch() computes the center channel
as "channel + 2" for OFFSET_LOWER, and bwmode_update_check() sets
OFFSET_LOWER when the AP's HT operation IE announces SCA (secondary
channel above). In nl80211 terms that is NL80211_CHAN_HT40PLUS, not
HT40MINUS.
Because of the inversion, cfg80211_rtw_get_channel() reports an HT40+
association as HT40-. For an HT40+ AP on a low channel (e.g. channel 3)
the resulting chandef spans below the 2.4 GHz band edge and is invalid,
so the regulatory core tears the connection down 60 seconds
(REG_ENFORCE_GRACE_MS) after the AP's country IE triggers a regdomain
change: reg_check_chans_work() considers the reported chandef unusable
and calls cfg80211_leave(). The supplicant then reconnects, the country
IE changes the regdomain again, and the cycle repeats, causing a
disconnect/reconnect loop every ~65 seconds for as long as the link is
up.
Observed on a TECLAST X80 Power tablet (RTL8723BS) associated to an
HT40+ AP on channel 3 with a KR country IE; a kprobe trace showed
cfg80211_disconnect() being invoked from reg_check_chans_work(). With
the mapping fixed, "iw dev wlan0 info" reports the correct
"width: 40 MHz, center1: 2432 MHz" and the periodic disconnects stop.

mpls: fix NULL deref in mpls_valid_fib_dump_req() on CONFIG_INET=n
On CONFIG_INET=n builds, mpls_valid_fib_dump_req() walks the parsed
attribute table itself instead of calling ip_valid_fib_dump_req(). The
RTA_OIF arm passes tb[RTA_OIF] to nla_get_u32() without checking it is
present, so an RTM_GETROUTE dump for AF_MPLS with strict checking and no

llc: fix SAP refcount leak when creating incoming sockets
llc_sap_add_socket() takes a SAP reference for each socket added to a SAP, and llc_sap_remove_socket() releases it. llc_create_incoming_sock() takes an additional SAP reference after adding the child socket. This extra reference was balanced by an explicit llc_sap_put() in llc_ui_release() until commit |

selftests: netconsole: only restore MAC when it changed on resume
The "mac" bind mode reactivation downs the interface, restores the saved
MAC and renames it to trigger a target resume. This assumes the recreated
interface comes back with a different MAC, which is true under
MACAddressPolicy=none (as on the Netdev CI) but not when MACs are
persistent. In the persistent case netconsole resumes the target on its
own, and the down/restore/rename flow instead drops it and fails the test.
Guard the block on the MAC having actually changed so the test passes
under both policies.

serial: sc16is7xx: implement gpio get_direction() callback
It's strongly recommended for GPIO drivers to always implement the
.get_direction() callback - even when the direction is tracked in
software. The GPIO core emits a warning when the callback is missing
and a user reads the direction of a line, e.g. via
/sys/kernel/debug/gpio.

bnxt_en: Handle partially initialized auxiliary devices
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
source review.

usb: atm: ueagle-atm: reject descriptors that confuse probe and disconnect
uea_probe() distinguishes a pre-firmware device from a post-firmware one
using the USB id (UEA_IS_PREFIRM()), and stores a different object as the
interface data in each case: a 'struct completion' for a pre-firmware
device (to be waited on in .disconnect()), or a 'struct usbatm_data' for a
post-firmware one.
uea_disconnect() instead tells the two apart by the number of interfaces
of the active configuration (a pre-firmware device exposes a single
interface, ADI930 has 2 and eagle has 3), and casts the interface data
accordingly.
Because the two handlers use different criteria, a crafted device that
advertises a pre-firmware id together with a multi-interface descriptor
(or a post-firmware id with a single interface) makes them disagree: the
small 'struct completion' stored by uea_probe() is then passed to
usbatm_usb_disconnect(), which casts it to 'struct usbatm_data' and takes
instance->serialize, reading past the end of the allocation:

sctp: fix auth_hmacs array size in struct sctp_cookie
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.

net/sched: act_tunnel_key: Defer dst_release to RCU callback
Fix a race-condition use-after-free in tunnel_key_release_params().
The function releases the metadata_dst of the old params synchronously
via dst_release() while deferring the params struct free with
kfree_rcu(). A concurrent tunnel_key_act() reader on the datapath may
still hold the old params pointer (under rcu_read_lock_bh) and proceed
to call dst_clone(¶ms->tcft_enc_metadata->dst) after the writer's
dst_release has already pushed the dst's rcuref to RCUREF_DEAD.

dpll: fix NULL pointer dereference in dpll_msg_add_pin_ref_sync()
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

net/mlx5: free mlx5_st_idx_data on final dealloc
Workloads that repeatedly allocate and release mkeys carrying TPH
steering-tag hints (e.g. churning RDMA MRs) leak one
struct mlx5_st_idx_data per cycle; kmemleak flags it as unreferenced
and the kmalloc slab grows over time.
When the last reference to an ST table entry is dropped,
mlx5_st_dealloc_index() removed the entry from idx_xa but the backing
mlx5_st_idx_data allocation was never freed.
Free idx_data after the xa_erase() so the lifetime of the bookkeeping
struct matches the lifetime of the ST entry it tracks.

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. netfilter pull request nf-26-07-10 * tag 'nf-26-07-10' of https://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf: netfilter: xt_physdev: masks are not c-strings ipvs: fix more places with wrong ipv6 transport offsets ipvs: reload ip header after head reallocation netfilter: flowtable: use correct direction to set up tunnel route selftests: netfilter: add bridge tunnel flowtable regression netfilter: nf_conncount: fix zone comparison in tuple dedup netfilter: bridge: fix stale prevhdr pointer in br_ip6_fragment() netfilter: ecache: fix inverted time_after() check netfilter: xt_nat: reject unsupported target families ==================== Link: https://patch.msgid.link/20260710143733.29741-1-fw@strlen.de Signed-off-by: Paolo Abeni <pabeni@redhat.com> |

accel/amdxdna: Fix use-after-free of mm_struct in job scheduler
amdxdna_cmd_submit() stores current->mm in job->mm without holding any
reference. aie2_sched_job_run() later access job->mm from the DRM
scheduler worker thread. With only a raw pointer and no structural
reference, the mm_struct can be freed before the scheduler runs the job.
Fix this by calling mmgrab() to hold a structural mm_count reference for
the lifetime of the job, paired with mmdrop() in every cleanup path.
Fixes:
