vmlinux.lds: Include .data.rel[.local] into .data section
When running in -fPIC mode, the compiler may decide to emit statically initialized data objects into .data.rel or .data.rel.local if they contain absolute references to global or local objects, respectively, which require fixing up at load time. This distinction is irrelevant for the kernel, so fold .data.rel and .data.rel.local into .data.

io_uring/zcrx: return ifq id to the user
IORING_OP_RECV_ZC requests take a zcrx object id via sqe::zcrx_ifq_idx, which binds it to the corresponding if / queue. However, we don't return that id back to the user. It's fine as currently there can be only one zcrx and the user assumes that its id should be 0, but as we'll need multiple zcrx objects in the future let's explicitly pass it back on registration.

mm: (un)track_pfn_copy() fix + doc improvements
We got a late smatch warning and some additional review feedback.
smatch warnings:
mm/memory.c:1428 copy_page_range() error: uninitialized symbol 'pfn'.
We actually use the pfn only when it is properly initialized; however, we
may pass an uninitialized value to a function -- although it will not use
it that likely still is UB in C.
So let's just fix it by always initializing pfn in the caller of
track_pfn_copy(), and improving the documentation of track_pfn_copy().
While at it, clarify the doc of untrack_pfn_copy(), that internal checks
make sure if we actually have to untrack anything.

fwctl/cxl: Fix uuid_t usage in uapi
The uuid_t type is kernel internal, and Paul reports the following build
error when it is used in a uapi header:
usr/include/cxl/features.h:59:9: error: unknown type name ‘uuid_t’
Create a uuid type (__uapi_uuid_t) compatible with the longstanding
definition uuid/uuid.h for userspace builds, and use uuid_t directly for
kernel builds.

firmware: cs_dsp: test_bin_error: Fix uninitialized data used as fw version
Call cs_dsp_mock_xm_header_get_fw_version() to get the firmware version
from the dummy XM header data in cs_dsp_bin_err_test_common_init().
Make the same change to cs_dsp_bin_test_common_init() and remove the
cs_dsp_mock_xm_header_get_fw_version_from_regmap() function.
The code in cs_dsp_test_bin.c was correctly calling
cs_dsp_mock_xm_header_get_fw_version_from_regmap() to fetch the fw version
from a dummy header it wrote to XM registers. However in
cs_dsp_test_bin_error.c the test doesn't stuff a dummy header into XM, it
populates it the normal way using a wmfw file. It should have called
cs_dsp_mock_xm_header_get_fw_version() to get the data from its blob
buffer, but was calling cs_dsp_mock_xm_header_get_fw_version_from_regmap().
As nothing had been written to the registers this returned the value of
uninitialized data.
The only other use of cs_dsp_mock_xm_header_get_fw_version_from_regmap()
was cs_dsp_test_bin.c, but it doesn't need to use it. It already has a
blob buffer containing the dummy XM header so it can use
cs_dsp_mock_xm_header_get_fw_version() to read from that.

vdso: Address variable shadowing in macros
Compiling the kernel with gcc12.3 W=2 results in shadowing warnings:
warning: declaration of '__pptr' shadows a previous local [-Wshadow]
const struct { type x; } __packed *__pptr = (typeof(__pptr))(ptr);
note: in definition of macro '__put_unaligned_t'
__pptr->x = (val);
note: in expansion of macro '__get_unaligned_t'
__put_unaligned_t(type, __get_unaligned_t(type, src), dst);
__get_unaligned_t() and __put_unaligned_t() use a local variable named
'__pptr', which can lead to variable shadowing when these macros are used in
the same scope. This results in a -Wshadow warning during compilation.
To address this issue, rename the local variables within the macros to
ensure uniqueness.

net: Fix null-ptr-deref by sock_lock_init_class_and_name() and rmmod.
When I ran the repro [0] and waited a few seconds, I observed two
LOCKDEP splats: a warning immediately followed by a null-ptr-deref. [1]
Reproduction Steps:
1) Mount CIFS
2) Add an iptables rule to drop incoming FIN packets for CIFS
3) Unmount CIFS
4) Unload the CIFS module
5) Remove the iptables rule
At step 3), the CIFS module calls sock_release() for the underlying
TCP socket, and it returns quickly. However, the socket remains in
FIN_WAIT_1 because incoming FIN packets are dropped.
At this point, the module's refcnt is 0 while the socket is still
alive, so the following rmmod command succeeds.
# ss -tan
State Recv-Q Send-Q Local Address:Port Peer Address:Port
FIN-WAIT-1 0 477 10.0.2.15:51062 10.0.0.137:445
# lsmod | grep cifs
cifs 1159168 0
This highlights a discrepancy between the lifetime of the CIFS module
and the underlying TCP socket. Even after CIFS calls sock_release()
and it returns, the TCP socket does not die immediately in order to
close the connection gracefully.
While this is generally fine, it causes an issue with LOCKDEP because
CIFS assigns a different lock class to the TCP socket's sk->sk_lock
using sock_lock_init_class_and_name().
Once an incoming packet is processed for the socket or a timer fires,
sk->sk_lock is acquired.
Then, LOCKDEP checks the lock context in check_wait_context(), where
hlock_class() is called to retrieve the lock class. However, since
the module has already been unloaded, hlock_class() logs a warning
and returns NULL, triggering the null-ptr-deref.
If LOCKDEP is enabled, we must ensure that a module calling
sock_lock_init_class_and_name() (CIFS, NFS, etc) cannot be unloaded
while such a socket is still alive to prevent this issue.
Let's hold the module reference in sock_lock_init_class_and_name()
and release it when the socket is freed in sk_prot_free().
Note that sock_lock_init() clears sk->sk_owner for svc_create_socket()
that calls sock_lock_init_class_and_name() for a listening socket,
which clones a socket by sk_clone_lock() without GFP_ZERO.

perf: Fix hang while freeing sigtrap event
Perf can hang while freeing a sigtrap event if a related deferred
signal hadn't managed to be sent before the file got closed:
perf_event_overflow()
task_work_add(perf_pending_task)
fput()
task_work_add(____fput())
task_work_run()
____fput()
perf_release()
perf_event_release_kernel()
_free_event()
perf_pending_task_sync()
task_work_cancel() -> FAILED
rcuwait_wait_event()
Once task_work_run() is running, the list of pending callbacks is
removed from the task_struct and from this point on task_work_cancel()
can't remove any pending and not yet started work items, hence the
task_work_cancel() failure and the hang on rcuwait_wait_event().
Task work could be changed to remove one work at a time, so a work
running on the current task can always cancel a pending one, however
the wait / wake design is still subject to inverted dependencies when
remote targets are involved, as pictured by Oleg:
T1 T2
fd = perf_event_open(pid => T2->pid); fd = perf_event_open(pid => T1->pid);
close(fd) close(fd)
<IRQ> <IRQ>
perf_event_overflow() perf_event_overflow()
task_work_add(perf_pending_task) task_work_add(perf_pending_task)
</IRQ> </IRQ>
fput() fput()
task_work_add(____fput()) task_work_add(____fput())
task_work_run() task_work_run()
____fput() ____fput()
perf_release() perf_release()
perf_event_release_kernel() perf_event_release_kernel()
_free_event() _free_event()
perf_pending_task_sync() perf_pending_task_sync()
rcuwait_wait_event() rcuwait_wait_event()
Therefore the only option left is to acquire the event reference count
upon queueing the perf task work and release it from the task work, just
like it was done before

drm/tests: helpers: Create kunit helper to destroy a drm_display_mode
A number of test suites call functions that expect the returned drm_display_mode to be destroyed eventually. However, none of the tests called drm_mode_destroy, which results in a memory leak. Since drm_mode_destroy takes two pointers as argument, we can't use a kunit wrapper. Let's just create a helper every test suite can use.

sctp: detect and prevent references to a freed transport in sendmsg
sctp_sendmsg() re-uses associations and transports when possible by doing a lookup based on the socket endpoint and the message destination address, and then sctp_sendmsg_to_asoc() sets the selected transport in all the message chunks to be sent. There's a possible race condition if another thread triggers the removal of that selected transport, for instance, by explicitly unbinding an address with setsockopt(SCTP_SOCKOPT_BINDX_REM), after the chunks have been set up and before the message is sent. This can happen if the send buffer is full, during the period when the sender thread temporarily releases the socket lock in sctp_wait_for_sndbuf(). This causes the access to the transport data in sctp_outq_select_transport(), when the association outqueue is flushed, to result in a use-after-free read. This change avoids this scenario by having sctp_transport_free() signal the freeing of the transport, tagging it as "dead". In order to do this, the patch restores the "dead" bit in struct sctp_transport, which was removed in commit |

mtd: spinand: Fix build with gcc < 7.5
__VA_OPT__ is a macro that is useful when some arguments can be present
or not to entirely skip some part of a definition. Unfortunately, it
is a too recent addition that some of the still supported old GCC
versions do not know about, and is anyway not part of C11 that is the
version used in the kernel.
Find a trick to remove this macro, typically '__VA_ARGS__ + 0' is a
workaround used in netlink.h which works very well here, as we either
expect:
- 0
- A positive value
- No value, which means the field should be 0.

A set of final cleanups for the timer subsystem:
1) Convert all del_timer[_sync]() instances over to the new
timer_delete[_sync]() API and remove the legacy wrappers.
Conversion was done with coccinelle plus some manual fixups as
coccinelle chokes on scoped_guard().
2) The final cleanup of the hrtimer_init() to hrtimer_setup() conversion.
This has been delayed to the end of the merge window, so that all
patches which have been merged through other trees are in mainline and
all new users are catched.
Doing this right before rc1 ensures that new code which is merged post rc1
is not introducing new instances of the original functionality.

A set of updates for the interrupt subsystem:
1) A treewide cleanup for the irq_domain code, which makes the naming
consistent and gets rid of the original oddity of naming domains
'host'.
This is a trivial mechanical change and is done late to ensure that
all instances have been catched and new code merged post rc1 wont
reintroduce new instances.
2) A trivial consistency fix in the migration code
The recent introduction of irq_force_complete_move() in the core
code, causes a problem for the nostalgia crowd who maintains ia64 out
of tree.
The code assumes that hierarchical interrupt domains are enabled and
dereferences irq_data::parent_data unconditionally. That works in mainline
because both architectures which enable that code have hierarchical domains
enabled. Though it breaks the ia64 build, which enables the functionality,
but does not have hierarchical domains.
While it's not really a problem for mainline today, this
unconditional dereference is inconsistent and trivially fixable by
using the existing helper function irqd_get_parent_data(), which has
the appropriate #ifdeffery in place.

Merge tag 'irq-urgent-2025-04-06' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull more irq updates from Thomas Gleixner:
"A set of updates for the interrupt subsystem:
- A treewide cleanup for the irq_domain code, which makes the naming
consistent and gets rid of the original oddity of naming domains
'host'.
This is a trivial mechanical change and is done late to ensure that
all instances have been catched and new code merged post rc1 wont
reintroduce new instances.
- A trivial consistency fix in the migration code
The recent introduction of irq_force_complete_move() in the core
code, causes a problem for the nostalgia crowd who maintains ia64
out of tree.
The code assumes that hierarchical interrupt domains are enabled
and dereferences irq_data::parent_data unconditionally. That works
in mainline because both architectures which enable that code have
hierarchical domains enabled. Though it breaks the ia64 build,
which enables the functionality, but does not have hierarchical
domains.
While it's not really a problem for mainline today, this
unconditional dereference is inconsistent and trivially fixable by
using the existing helper function irqd_get_parent_data(), which
has the appropriate #ifdeffery in place"
* tag 'irq-urgent-2025-04-06' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
genirq/migration: Use irqd_get_parent_data() in irq_force_complete_move()
irqdomain: Stop using 'host' for domain
irqdomain: Rename irq_get_default_host() to irq_get_default_domain()
irqdomain: Rename irq_set_default_host() to irq_set_default_domain()

tracing/timers: Rename the hrtimer_init event to hrtimer_setup
The function hrtimer_init() doesn't exist anymore. It was replaced by hrtimer_setup(). Thus, rename the hrtimer_init trace event to hrtimer_setup to keep it consistent.
