Pull tracing fixes from Steven Rostedt:
- Fix some missing-prototype warnings
- Fix user events struct args (did not include size of struct)
When creating a user event, the "struct" keyword is to denote that
the size of the field will be passed in. But the parsing failed to
handle this case.
- Add selftest to struct sizes for user events
- Fix sample code for direct trampolines.
The sample code for direct trampolines attached to handle_mm_fault().
But the prototype changed and the direct trampoline sample code was
not updated. Direct trampolines needs to have the arguments correct
otherwise it can fail or crash the system.
- Remove unused ftrace_regs_caller_ret() prototype.
- Quiet false positive of FORTIFY_SOURCE
Due to backward compatibility, the structure used to save stack
traces in the kernel had a fixed size of 8. This structure is
exported to user space via the tracing format file. A change was made
to allow more than 8 functions to be recorded, and user space now
uses the size field to know how many functions are actually in the
stack.
But the structure still has size of 8 (even though it points into the
ring buffer that has the required amount allocated to hold a full
stack.
This was fine until the fortifier noticed that the
memcpy(&entry->caller, stack, size) was greater than the 8 functions
and would complain at runtime about it.
Hide this by using a pointer to the stack location on the ring buffer
instead of using the address of the entry structure caller field.
- Fix a deadloop in reading trace_pipe that was caused by a mismatch
between ring_buffer_empty() returning false which then asked to read
the data, but the read code uses rb_num_of_entries() that returned
zero, and causing a infinite "retry".
- Fix a warning caused by not using all pages allocated to store ftrace
functions, where this can happen if the linker inserts a bunch of
"NULL" entries, causing the accounting of how many pages needed to be
off.
- Fix histogram synthetic event crashing when the start event is
removed and the end event is still using a variable from it
- Fix memory leak in freeing iter->temp in tracing_release_pipe()

Eric Dumazet says[1]:
-------
Speaking of psched_mtu(), I see that net/sched/sch_pie.c is using it
without holding RTNL, so dev->mtu can be changed underneath.
KCSAN could issue a warning.

Annotate dev->mtu with READ_ONCE() so KCSAN don't issue a warning.

rethook_free()
Ensure running fprobe_exit_handler() has finished before
calling rethook_free() in the unregister_fprobe() so that caller can free
the fprobe right after unregister_fprobe().
unregister_fprobe() ensured that all running fprobe_entry/exit_handler()
have finished by calling unregister_ftrace_function() which synchronizes
RCU. But commit 5f81018753df ("fprobe: Release rethook after the ftrace_ops
is unregistered") changed to call rethook_free() after
unregister_ftrace_function(). So call rethook_stop() to make rethook
disabled before unregister_ftrace_function() and ensure it again.
Here is the possible code flow that can call the exit handler after
unregister_fprobe().
------
CPU1 CPU2
call unregister_fprobe(fp)
...
__fprobe_handler()
rethook_hook() on probed function
unregister_ftrace_function()
return from probed function
rethook hooks
find rh->handler == fprobe_exit_handler
call fprobe_exit_handler()
rethook_free():
set rh->handler = NULL;
return from unreigster_fprobe;
call fp->exit_handler() <- (*)
------
(*) At this point, the exit handler is called after returning from
unregister_fprobe().
This fixes it as following;
------
CPU1 CPU2
call unregister_fprobe()
...
rethook_stop():
set rh->handler = NULL;
__fprobe_handler()
rethook_hook() on probed function
unregister_ftrace_function()
return from probed function
rethook hooks
find rh->handler == NULL
return from rethook
rethook_free()
return from unreigster_fprobe;

commit dd0ff4d12dd2 ("bootmem: remove the vmemmap pages from kmemleak in
put_page_bootmem") fix an overlaps existing problem of kmemleak. But the
problem still existed when HAVE_BOOTMEM_INFO_NODE is disabled, because in
this case, free_bootmem_page() will call free_reserved_page() directly.
Fix the problem by adding kmemleak_free_part() in free_bootmem_page() when
HAVE_BOOTMEM_INFO_NODE is disabled.

Previously the clients_lock was protecting the clients array against
concurrent addition/removal of clients but was also accessed from IRQ
context. This meant that it had to be a spinlock and that the add() and
remove() callbacks in which clients need to do allocation and take
mutexes can't be called under the clients_lock. To work around this these
callbacks were moved to workqueues. This not only introduced significant
complexity but is also subtly broken in at least one way.
In ism_dev_init() and ism_dev_exit() clients[i]->tgt_ism is used to
communicate the added/removed ISM device to the work function. While
write access to client[i]->tgt_ism is protected by the clients_lock and
the code waits that there is no pending add/remove work before and after
setting clients[i]->tgt_ism this is not enough. The problem is that the
wait happens based on per ISM device counters. Thus a concurrent
ism_dev_init()/ism_dev_exit() for a different ISM device may overwrite
a clients[i]->tgt_ism between unlocking the clients_lock and the
subsequent wait for the work to finnish.
Thankfully with the clients_lock no longer held in IRQ context it can be
turned into a mutex which can be held during the calls to add()/remove()
completely removing the need for the workqueues and the associated

The clients array references all registered clients and is protected by
the clients_lock. Besides its use as general list of clients the clients
array is accessed in ism_handle_irq() to forward ISM device events to
clients.
While the clients_lock is taken in the IRQ handler when calling
handle_event() it is however incorrectly not held during the
client->handle_irq() call and for the preceding clients[] access leaving
it unprotected against concurrent client (un-)registration.
Furthermore the accesses to ism->sba_client_arr[] in ism_register_dmb()
and ism_unregister_dmb() are not protected by any lock. This is
especially problematic as the client ID from the ism->sba_client_arr[]
is not checked against NO_CLIENT and neither is the client pointer
checked.
Instead of expanding the use of the clients_lock further add a separate
array in struct ism_dev which references clients subscribed to the
device's events and IRQs. This array is protected by ism->lock which is
already taken in ism_handle_irq() and can be taken outside the IRQ
handler when adding/removing subscribers or the accessing
ism->sba_client_arr[]. This also means that the clients_lock is no
longer taken in IRQ context.

since the ocelot switch lib does not have access to functions private to
the DSA wrapper.

In a future commit we will have to call vsc9959_tas_guard_bands_update()
from ocelot_port_update_active_preemptible_tcs(), and that will be
impossible due to the AB/BA locking dependencies between
ocelot->tas_lock and ocelot->fwd_domain_lock.
Just like we did in commit 3ff468ef987e ("net: mscc: ocelot: remove
struct ocelot_mm_state :: lock"), the only solution is to expand the
scope of ocelot->fwd_domain_lock for it to also serialize changes made
to the Time-Aware Shaper, because those will have to result in a
recalculation of cut-through TCs, which is something that depends on the
forwarding domain.

Originally this used jhash2() over tuple and folded the zone id,
the pernet hash value, destination port and l4 protocol number into the
32bit seed value.
When the switch to siphash was done, I used an on-stack temporary
buffer to build a suitable key to be hashed via siphash().
But this showed up as performance regression, so I got rid of
the temporary copy and collected to-be-hashed data in 4 u64 variables.
This makes it easy to build tuples that produce the same hash, which isn't
desirable even though chain lengths are limited.
Switch back to plain siphash, but just like with jhash2(), take advantage
of the fact that most of to-be-hashed data is already in a suitable order.
Use an empty struct as annotation in 'struct nf_conntrack_tuple' to mark
last member that can be used as hash input.
The only remaining data that isn't present in the tuple structure are the
zone identifier and the pernet hash: fold those into the key.

Overflow use refcount checks are not complete.
Add helper function to deal with object reference counter tracking.
Report -EMFILE in case UINT_MAX is reached.
nft_use_dec() splats in case that reference counter underflows,
which should not ever happen.
Add nft_use_inc_restore() and nft_use_dec_restore() which are used
to restore reference counter from error and abort paths.
Use u32 in nft_flowtable and nft_object since helper functions cannot
work on bitfields.
Remove the few early incomplete checks now that the helper functions
are in place and used to check for refcount overflow.

incl_srcpt has the limitation, mentioned in commit b4638af8885a ("net:
dsa: sja1105: always enable the INCL_SRCPT option"), that frames with a
MAC DA of 01:80:c2:xx:yy:zz will be received as 01:80:c2:00:00:zz unless
PTP RX timestamping is enabled.
The incl_srcpt option was initially unconditionally enabled, then that
changed with commit 42824463d38d ("net: dsa: sja1105: Limit use of
incl_srcpt to bridge+vlan mode"), then again with b4638af8885a ("net:
dsa: sja1105: always enable the INCL_SRCPT option"). Bottom line is that
it now needs to be always enabled, otherwise the driver does not have a
reliable source of information regarding source_port and switch_id for
link-local traffic (tag_8021q VLANs may be imprecise since now they
identify an entire bridging domain when ports are not standalone).
If we accept that PTP RX timestamping (and therefore, meta frame
generation) is always enabled in hardware, then that limitation could be
avoided and packets with any MAC DA can be properly received, because
meta frames do contain the original bytes from the MAC DA of their
associated link-local packet.
This change enables meta frame generation unconditionally, which also
has the nice side effects of simplifying the switch control path
(a switch reset is no longer required on hwtstamping settings change)
and the tagger data path (it no longer needs to be informed whether to
expect meta frames or not - it always does).

strlcpy() reads the entire source buffer first.
This read may exceed the destination size limit.
This is both inefficient and can lead to linear read
overflows if a source string is not NUL-terminated [1].
In an effort to remove strlcpy() completely [2], replace
strlcpy() here with strscpy().
No return values were used, so direct replacement is safe.

"This consist of three parts; UAPI update, OHCI driver update, and
several bug fixes.
Firstly, the 1394 OHCI specification defines method to retrieve
hardware time stamps for asynchronous communication, which was
previously unavailable in user space. This adds new events to the
UAPI, allowing applications to retrieve the time when asynchronous
packet are received and sent. The new events are tested in the
bleeding edge of libhinawa and look to work well. The new version of
libhinawa will be released after current merge window is closed:
https://git.kernel.org/pub/scm/libs/ieee1394/libhinawa.git/

After a change to the bnxt_re driver, it fails to link when
CONFIG_INFINIBAND_USER_ACCESS is disabled:
aarch64-linux-ld: drivers/infiniband/hw/bnxt_re/ib_verbs.o: in function `bnxt_re_handler_BNXT_RE_METHOD_ALLOC_PAGE':
ib_verbs.c:(.text+0xd64): undefined reference to `ib_uverbs_get_ucontext_file'
aarch64-linux-ld: drivers/infiniband/hw/bnxt_re/ib_verbs.o:(.rodata+0x168): undefined reference to `uverbs_idr_class'
aarch64-linux-ld: drivers/infiniband/hw/bnxt_re/ib_verbs.o:(.rodata+0x1a8): undefined reference to `uverbs_destroy_def_handler'
The problem is that the 'bnxt_re_uapi_defs' structure is built
unconditionally and references a couple of functions that are never
really called in this configuration but instead require other functions
that are left out.
Adding an #ifdef around the new code, or a Kconfig dependency would
address this problem, but adding the compile-time check inside of the
UAPI_DEF_CHAIN_OBJ_TREE_NAMED() macro seems best because that also
addresses the problem in other drivers that may run into the same
dependency.

Pull kvm updates from Paolo Bonzini:
"ARM64:
- Eager page splitting optimization for dirty logging, optionally
allowing for a VM to avoid the cost of hugepage splitting in the
stage-2 fault path.
- Arm FF-A proxy for pKVM, allowing a pKVM host to safely interact
with services that live in the Secure world. pKVM intervenes on
FF-A calls to guarantee the host doesn't misuse memory donated to
the hyp or a pKVM guest.
- Support for running the split hypervisor with VHE enabled, known as
'hVHE' mode. This is extremely useful for testing the split
hypervisor on VHE-only systems, and paves the way for new use cases
that depend on having two TTBRs available at EL2.
- Generalized framework for configurable ID registers from userspace.
KVM/arm64 currently prevents arbitrary CPU feature set
configuration from userspace, but the intent is to relax this
limitation and allow userspace to select a feature set consistent
with the CPU.
- Enable the use of Branch Target Identification (FEAT_BTI) in the
hypervisor.
- Use a separate set of pointer authentication keys for the
hypervisor when running in protected mode, as the host is untrusted
at runtime.
- Ensure timer IRQs are consistently released in the init failure
paths.
- Avoid trapping CTR_EL0 on systems with Enhanced Virtualization
Traps (FEAT_EVT), as it is a register commonly read from userspace.
- Erratum workaround for the upcoming AmpereOne part, which has
broken hardware A/D state management.

- Redirect AMO load/store misaligned traps to KVM guest
- Trap-n-emulate AIA in-kernel irqchip for KVM guest
