The IPIP and IP6IP6 tunnel tests call check_counters() to verify
flowtable offloading occurred, but the flow-add rule only matches
meta oif "veth1". When traffic is routed through a tunnel device,
oif is the tunnel interface (tun0, tun6, etc.), not veth1, so
the flow-add rule never fires, no flowtable entry is created,
and counters stay at zero — producing a silent false pass.
Fix by adding tunnel-specific flow-add rules for each tunnel
interface. These match TCP dport 12345 traffic before the bare
accept rule, set ct mark, add the flow to the flowtable, and
increment routed_orig. The existing routed_repl rule on veth0
already handles the reply direction since decapsulated reply
packets exit through the physical interface.
Also add check_counters() for the IP6IP6 non-VLAN and
IP6IP6-over-VLAN tests which previously used a bare PASS message.

Add a test that sends 2 MB of data using randomly sized small packets
(129-512 bytes) over a SOCK_STREAM connection. Packets above
GOOD_COPY_LEN (128) bypass the in-place coalescing in recv_enqueue(),
forcing each one into its own skb.
Without receive queue collapsing, the per-skb overhead eventually
exceeds buf_alloc and the connection is reset. The test verifies
that all data arrives and that content integrity is preserved.

The IPv6 addresses used for the tun_vnet_udptnl fixture currently fall in
the 2002::/16 prefix, which is reserved for the 6to4 transition mechanism
(RFC 3056).
On systems where the sit module is loaded, the kernel automatically claims
2002::/16 as a 6to4 tunnel prefix. When the test assigns a 2002:: address
to a TUN interface, sit registers a competing local route for the same
address. This ambiguity breaks the GENEVE decapsulation path: packets
injected via the TUN fd are not delivered to the test socket, causing the
IPv6-outer gtgso send_gso_packet variants to fail.
Replace all four IPv6 test addresses with addresses from the fd00:db8::/32
range, which is part of the ULA space (fc00::/7, RFC 4193) and carries no
special kernel semantics.

Pull tracing fixes from Steven Rostedt:
- Free field in error path of synthetic event parse
In __create_synth_event() the field was allocated but was not freed
in the error path
- Fix ring_buffer_event_length() on 8 byte aligned architectures
On architectures with CONFIG_HAVE_64BIT_ALIGNED_ACCESS set to y, the
ring_buffer_event_length() may return the wrong size. This is because
archs with that config set will always use the "big event meta
header" as that is 8 bytes keeping the payload 8 bytes aligned, even
when a 4 byte header could hold the size of the event
But ring_buffer_event_length() doesn't take this into account and
only subtracts 4 bytes for the meta header in the length when it
should have subtracted 8 bytes
- Have osnoise wait for a full rcu synchronization on unregister
osnoise_unregister_instance() used to call synchronize_rcu() before
freeing its copy of the instance but was switched to kfree_rcu(). The
osniose tracer has code that traverses the instances that it uses,
and inst is just a pointer to that instance. By using kfree_rcu()
instead of synchronize_rcu(), the instance that the inst pointer is
pointing to can be freed while the osnoise code is still referencing
it
That is, a rmdir on an instance first unregisters the tracer. When
the unregister finishes, the rmdir expects that the tracer is
finished with the instance that it is using. By putting back the
synchronize_rcu() in osnoise_unregister_instance() the unregistering
of osnoise will now return when all the users of the instance have
finished
- Remove an unused setting of "ret" in tracing_set_tracer()
- Fix ring_buffer_read_page() copying events
The commit that changed ring_buffer_read_page() to show dropped
events from the buffer itself, split the "commit" variable between
the commit value (with flags) and "size" that holds the size of the
sub-buffer. A cut and paste error changed the test of the reading
from checking the size of the buffer to the size of the event causing
reads to only read one event at a time
- Make tracepoint_printk a static variable
When the tracing sysctl knobs were move from sysctl.c to trace.c, the
variable tracepoint_printk no longer needed to be global. Make it
static
- Fix some typos
- Fix NULL pointer dereference in func_set_flag()
The flags update of the function tracer first checks if the value of
the flag is the same and exits if they are, and then it checks if the
current tracer is the function tracer and exits if it isn't. The
problem is that these checks need to be in a reversed order, as if
the tracer isn't the function tracer, then the flag being checked may
not exist. Reverse the order of these checks
- Fix ufs core trace events to not dereference a pointer in TP_printk()
The TP_printk() part of the TRACE_EVENT() macro is called when the
user reads the "trace" file. This can be seconds, minutes, hours,
days, weeks, and even months after the data was recorded into the
ring buffer. Thus, saving a pointer to an object into the ring buffer
and then dereferencing it from TP_printk() can cause harm as the
object the pointer is pointing to may no longer exist
Fix all the trace events in ufs core to save the device name in the
ring buffer instead of dereferencing the device descriptor from
TP_printk()
- Prevent out-of-bound reads in glob matching of trace events
The filter logic of events allows simple glob logic to add wild cards
to filter on strings. But some events have fields that may not have a
terminating 'nul' character. This may cause the glob matching to go
beyond the string. Change the logic to always pass in the length of
the field that is being matched
- Add no-rcu-check version of trace_##event##_enabled()
The trace_##event##_enabled() usually wraps trace events to do extra
work that is only needed when the trace event is enabled. But this
can hide events that are placed in locations where RCU is not
watching, and can make lockdep not see these bugs when the event is
not enabled
The trace_##event##_enabled() was updated to always test to make sure
RCU is watching to catch locations that may call events without RCU
being active
This caused a false positive for the irq_disabled() and related
events. As that use trace_irq_disabled_enabled() to force RCU to be
watching when the event is enabled via the ct_irq_enter() function,
calls the event, and then calls ct_irq_exit() to put RCU back to its
original state
The trace_irq_disabled_enabled() should not trigger a warning when
RCU is not watching because the code within its block handles the
case properly. Make a __trace_##event##_enabled() version for this
event to use that doesn't check RCU is watching as it handles the
case when it isn't
- Fix use-after-free in user_event_mm_dup()
When the enabler is removed from the link list, it is freed
immediately. But it is protected via RCU and needs to be freed after
an RCU grace period. Use queue_rcu_work() so that the event_mutex can
also be taken as user_event_put() takes the mutex on the last
reference is released
- Free type string in error path of parse_synth_field()
There's an error path in parse_synth_field() where the allocated type
string is not freed
- Add selftest that tests deferred event teardown
- Fix leak in error path of trace_remote_alloc_buffer()
If page allocation fails, the desc->nr_cpus is not incremented for
the current CPU and the allocations done for it are not freed
- Fix allocation length in trace_remote_alloc_buffer()
The logic to calculate the struct_len was doing a double count and
setting the value too large. Calculate the size upfront to fix the
error and simplify the logic
- Fix sparse CPU masks in ring_buffer_desc()
If there are sparse CPUs (gaps in the numbering), the
ring_buffer_desc() will fail as it tests the CPU number against the
number of CPUs that are used

Currently trigger-hist-poll.tc uses sched_process_free to test the polling
of the histogram file. The way it does that is to run sleep, then execute
the poll.c code that polls on the sched_process_free for up to 4 seconds
to test that when sleep triggers the sched_process_free trace event, it
will update the histogram and wake the poll.c code up.
The issue is that sched_process_free trace event is called by
delayed_put_task_struct() which is called after a RCU grace period has
ended. If CONFIG_RCU_LAZY is enabled, RCU callbacks are batched together
and do not execute right away. This causes the delayed_put_task_struct()
to be called after the poll.c function finishes and it will report an
error that it did not wake up on the event. That's because the event
didn't trigger during its wait time.
Use sched_process_exit instead, which is called when a process exits and
doesn't depend on RCU callbacks that may be delayed.

The add_remove_fprobe_module test checks the number of functions added to
the enabled_functions file to make sure that the functions added or
removed is as expected. The issue is that it expects this file to be empty
on start up.
Now that systemd uses BPF that attaches to functions via ftrace, this file
is not empty in several systems:
# cat /sys/kernel/tracing/enabled_functions
bpf_lsm_file_open (1) R D M tramp: ftrace_regs_caller+0x0/0x61 (call_direct_funcs+0x0/0x50)
direct(jmp)-->bpf_trampoline_6442529439+0x0/0xe9
Change the test to read the number of lines in enabled_functions at the
start of the test and subtract that from the value of the count for the
checks within the test.

The scoped_signal_test uses pthread_join(..., (void **)&ret)) in
a couple of places, i.e. the return value of the thread is stored
in the shape of a "void *" into the memory location of &ret.
Pointers are 64-bit on modern computers, but the ret variable is
declared as a simple "enum thread_return" which is only 32 bits.
So the pthread_join() will overflow the ret variable by 4 byte.
The problem is very visible on big endian systems like s390x
where the test is failing: The least significant byte that carries
the return code of the thread is not written into the ret variable
here, but somewhere else in the stack frame, so the comparison
for the right return code is failing here.
Fix it by getting rid of the enum and defining the THREAD_* constants
and "ret" variables as proper "void *" pointers. This way we can
also get rid of some ugly (void *) castings in a couple of spots.

cmask_equal(), cmask_weight() and cmask_subset() bounded their word walks
with CMASK_NR_WORDS(nr_cids), which pads by one word and can't tell the last
word in use without @base. The walks could thus cover a slack word past the
active range, which cmask_reframe() leaves non-zero: a stale bit there gave
cmask_equal() a spurious mismatch, cmask_weight() an inflated count, and
cmask_subset() a spurious violation. cmask_subset() could also read
@b->bits[] one word past its allocation (within the arena's fault-recovered
range, so harmless), and deviated from the kernel scx_cmask_subset() by
failing any @a range that doesn't nest inside @b's even when the overhanging
bits are all clear.
Bound the cmask_equal() and cmask_weight() walks by the words the range
actually spans, with early returns for empty ranges. Rewrite cmask_subset()
to match the kernel semantics: scan @a's overhangs for set bits with
cmask_next_set() and walk the words of the range intersection.
cmask_subset() moves below cmask_next_set(), which it now uses. Padding bits
don't need masking as every cmask helper keeps them clear.

Unregistering a user event now defers the drop of the enabler's event
reference (and the freeing of the enabler) past an RCU grace period. As a
result DIAG_IOCSDEL can transiently fail with -EBUSY while that last
reference is still being dropped, where it previously succeeded
immediately.
Two tests assumed the delete takes effect the instant the unregister
returns:
- abi_test "flags" deletes the event right after disabling it.
- perf_test's fixture teardown clear() deletes __test_event before the
next test registers the same name; a stale event makes the following
registration fail with -EADDRINUSE.
Retry the delete until it succeeds (or the event is already gone) with a
bounded wait, matching the existing wait_for_delete() idiom in the same
suite, so the tests are robust to the deferred teardown.

The ptrace_v_not_enabled test expects the child to reach its ebreak
before it has used the vector extension. That is not guaranteed when
using fork(), because libc may run child atfork handlers before
returning to the test code. In those cases PTRACE_GETREGSET for
NT_RISCV_VECTOR then succeeds instead of returning ENODATA for
inactive vector state.
Use the raw clone syscall with SIGCHLD to keep fork-like semantics
while bypassing libc's fork wrapper and atfork handler chain.

In the ctl_value_index_valid() function, when validating 64-bit integer
controls (SND_CTL_ELEM_TYPE_INTEGER64), the error message for maximum
value validation has two bugs:
1. Uses snd_ctl_elem_info_get_max() instead of the 64-bit variant
snd_ctl_elem_info_get_max64()
2. Uses %ld format specifier instead of %lld for long long type
This is inconsistent with the minimum value validation (line 335-339)
which correctly uses get_min64() and %lld. The mismatch can cause:
- Incorrect maximum values being reported on some architectures
- Undefined behavior due to format specifier mismatch
- Potential crashes when printing the error message
Fix by using snd_ctl_elem_info_get_max64() and %lld format specifier
to match the data type and be consistent with the minimum value check.

- netfs:
- fix the decision when to disallow write-streaming with fscache in
use, handling of asynchronous cache object creation, a double fput
in cachefiles, clearing S_KERNEL_FILE without the inode lock held,
page extraction bugs in the iov_iter helpers (a potential
underflow, a missing allocation failure check, a memory leak, and
a folio offset miscalculation), writeback error and ENOMEM
handling, DIO write retry for filesystems without a
->prepare_write() method, and the replacement of the wb_lock mutex
with a bit lock plus writethrough collection offload so that
multiple asynchronous writebacks don't interfere with each other.
- Fix the barriering when walking the netfs subrequest list during
retries as it was possible to see a subrequest that was just added
by the application thread.
- iomap:
- Change iomap to submit read bios after each extent instead of
building them up across extents. The old behavior was considered
problematic for a while and now caused an actual erofs bug.
- Guard the ioend io_size EOF trim in iomap against underflow when a
concurrent truncate moves EOF below the start of the ioend,
wrapping io_size to a huge value.
- overlayfs
- Fix a stale overlayfs comment about the locking order.
- Store the linked-in upper dentry instead of the disconnected
O_TMPFILE dentry during overlayfs tmpfile copy-up. With a FUSE or
virtiofs upper layer ->d_revalidate() would try to look up "/" in
the workdir and fail, causing persistent ESTALE errors that broke
dpkg and apt.
- vfs-bpf:
Have the bpf_real_data_inode() kfunc take a struct file instead of a
dentry so it is usable from the bprm_check_security, mmap_file, and
file_mprotect hooks, and rename it from bpf_real_inode() to make the
data-inode semantics explicit. The kfunc landed this cycle so the
change is safe.
- afs:
NULL pointer dereferences in the callback service and in
afs_get_tree(), several memory and refcount leaks, missing locking
around the dynamic root inode numbers and premature cell exposure
through /afs, a netns destruction hang caused by a misplaced
increment of net->cells_outstanding, a bulk lookup malfunction caused
by the dir_emit() API change, inode (re)initialisation issues, and
assorted smaller fixes to error codes, seqlock handling, and debug
output.

selftest for it.
- vboxsf:
Add Jori Koolstra as vboxsf maintainer, taking over from Hans de
Goede.
- dio:
Release the pages attached to a short atomic dio bio; the REQ_ATOMIC
size check error path leaked them.
- procfs:
Only bump the parent directory link count when registering
directories in procfs. Registering regular files inflated the count
and leaked a link on every create and remove cycle.
- minix:
Avoid an unsigned overflow in the minix bitmap block count
calculation that let crafted images with huge inode or zone counts
pass superblock validation and crash the kernel during mount.
- cachefiles:
Fix a double unlock in the cachefiles nomem_d_alloc error path left
over from the start_creating() conversion.
- fat:
Stop fat from reading directory entries past the 0x00
end-of-directory marker. If the trailing on-disk slots aren't
zero-filled the driver surfaced arbitrary garbage as directory
entries.
- freexvfs:
Don't BUG() on unknown typed-extent types in freevxfs, reachable via
ioctl(FIBMAP) on a crafted image; fail with an I/O error instead.
- orangefs:
Keep the readdir entry size 64-bit in orangefs fill_from_part().
Truncating it to __u32 bypassed the bounds check and led to
out-of-bounds reads triggerable by the userspace client.
- xfs:
Fix the error unwind in xfs_open_devices() which released the rt
device file twice and left dangling buftarg pointers behind that were
freed again when the failed mount was torn down.
- exec:
Fix an off-by-one in the comment documenting the maximum binfmt
rewrite depth in exec_binprm(). The code allows five rewrites, not
four; restricting the code would break userspace so the comment is
fixed instead.
- file handles:
Reject detached mounts in capable_wrt_mount(). A detached mount can
be dissolved concurrently, leaving a NULL mount namespace that
open_by_handle_at() would dereference.

Pull mod_devicetable.h header split from Uwe Kleine-König:
"Split <linux/mod_devicetable.h> in per subsystem headers
<linux/mod_devicetable.h> is included transitively in nearly every
driver in an x86_64 allmodconfig build of v7.1:
$ find drivers -name \*.o -not -name \*.mod.o | wc -l
21330
$ find drivers -name \*.o.cmd -not -name \*.mod.o.cmd | xargs grep -l mod_devicetable.h | wc -l
17038
The result of this mixture of different and unrelated subsystem
details is that even when touching an obscure device id struct most of
the kernel needs to be recompiled. Given that each driver typically
only needs one or two of these structures, splitting into per
subsystem headers and only including what is really needed reduces the
amount of needed recompilation.
This split is implemented in the first commit and then after some
preparatory work in the following commits, the last two replace
includes of <linux/mod_devicetable.h> by the actually needed more
specific headers.
There are still a few instances left, but the ones with high impact
(that is in headers that are used a lot) and the easy ones (.c files)
are handled. These remaining includes will be addressed during the
next merge window"
