In [1] the meaning of the synthetic IBPB flags has been redefined for a
better separation of concerns:
- ENTRY_IBPB -- issue IBPB on entry only
- IBPB_ON_VMEXIT -- issue IBPB on VM-Exit only
and the Retbleed mitigations have been updated to match this new
semantics.
Commit [2] was merged shortly before [1], and their interaction was not
handled properly. This resulted in IBPB not being triggered on VM-Exit
in all SRSO mitigation configs requesting an IBPB there.
Specifically, an IBPB on VM-Exit is triggered only when
X86_FEATURE_IBPB_ON_VMEXIT is set. However:
- X86_FEATURE_IBPB_ON_VMEXIT is not set for "spec_rstack_overflow=ibpb",
because before [1] having X86_FEATURE_ENTRY_IBPB was enough. Hence,
an IBPB is triggered on entry but the expected IBPB on VM-exit is
not.
- X86_FEATURE_IBPB_ON_VMEXIT is not set also when
"spec_rstack_overflow=ibpb-vmexit" if X86_FEATURE_ENTRY_IBPB is
already set.
That's because before [1] this was effectively redundant. Hence, e.g.
a "retbleed=ibpb spec_rstack_overflow=bpb-vmexit" config mistakenly
reports the machine still vulnerable to SRSO, despite an IBPB being
triggered both on entry and VM-Exit, because of the Retbleed selected
mitigation config.
- UNTRAIN_RET_VM won't still actually do anything unless
CONFIG_MITIGATION_IBPB_ENTRY is set.
For "spec_rstack_overflow=ibpb", enable IBPB on both entry and VM-Exit
and clear X86_FEATURE_RSB_VMEXIT which is made superfluous by
X86_FEATURE_IBPB_ON_VMEXIT. This effectively makes this mitigation
option similar to the one for 'retbleed=ibpb', thus re-order the code
for the RETBLEED_MITIGATION_IBPB option to be less confusing by having
all features enabling before the disabling of the not needed ones.
For "spec_rstack_overflow=ibpb-vmexit", guard this mitigation setting
with CONFIG_MITIGATION_IBPB_ENTRY to ensure UNTRAIN_RET_VM sequence is
effectively compiled in. Drop instead the CONFIG_MITIGATION_SRSO guard,
since none of the SRSO compile cruft is required in this configuration.
Also, check only that the required microcode is present to effectively
enabled the IBPB on VM-Exit.
Finally, update the KConfig description for CONFIG_MITIGATION_IBPB_ENTRY
to list also all SRSO config settings enabled by this guard.

Commit ba5095ebbc7a ("mfd: syscon: Allow syscon nodes without a
"syscon" compatible") broke drivers which call device_node_to_regmap()
on nodes without a "syscon" compatible. Restore the prior behavior for
device_node_to_regmap().
This also makes using device_node_to_regmap() incompatible with
of_syscon_register_regmap() again, so add kerneldoc for
device_node_to_regmap() and syscon_node_to_regmap() to make it clear
how and when each one should be used.

Jeff says:
Now that I look, 1b3e26a5ccbf is wrong. The patch on the ml was correct, but
the one that got committed is different. It should be:
status = decode_cb_op_status(xdr, OP_CB_GETATTR, &cb->cb_status);
if (unlikely(status || cb->cb_status))
If "status" is non-zero, decoding failed (usu. BADXDR), but we also want to
bail out and not decode the rest of the call if the decoded cb_status is
non-zero. That's not happening here, cb_seq_status has already been checked and
is non-zero, so this ends up trying to decode the rest of the CB_GETATTR reply
when it doesn't exist.

If nfs4_client is in courtesy state then there is no point to send

A recent patch moved the assignment of seq->maxslots from before the

in it not being run in that case. This results in the server returning

Commit 3775fc538f53 ("PM: sleep: core: Synchronize runtime PM status of
parents and children") exposed an issue related to simple_pm_bus_pm_ops
that uses pm_runtime_force_suspend() and pm_runtime_force_resume() as
bus type PM callbacks for the noirq phases of system-wide suspend and
resume.
The problem is that pm_runtime_force_suspend() does not distinguish
runtime-suspended devices from devices for which runtime PM has never
been enabled, so if it sees a device with runtime PM status set to
RPM_ACTIVE, it will assume that runtime PM is enabled for that device
and so it will attempt to suspend it with the help of its runtime PM
callbacks which may not be ready for that. As it turns out, this
causes simple_pm_bus_runtime_suspend() to crash due to a NULL pointer
dereference.
Another problem related to the above commit and simple_pm_bus_pm_ops is
that setting runtime PM status of a device handled by the latter to
RPM_ACTIVE will actually prevent it from being resumed because
pm_runtime_force_resume() only resumes devices with runtime PM status
set to RPM_SUSPENDED.
To mitigate these issues, do not allow power.set_active to propagate
beyond the parent of the device with DPM_FLAG_SMART_SUSPEND set that
will need to be resumed, which should be a sufficient stop-gap for the
time being, but they will need to be properly addressed in the future
because in general during system-wide resume it is necessary to resume
all devices in a dependency chain in which at least one device is going
to be resumed.

The code was restructured where the function graph notrace code, that
would not trace a function and all its children is done by setting a
NOTRACE flag when the function that is not to be traced is hit.
There's a TRACE_GRAPH_NOTRACE_BIT which defines the bit in the flags and a
TRACE_GRAPH_NOTRACE which is the mask with that bit set. But the
restructuring used TRACE_GRAPH_NOTRACE_BIT when it should have used
TRACE_GRAPH_NOTRACE.
For example:
# cd /sys/kernel/tracing
# echo set_track_prepare stack_trace_save > set_graph_notrace
# echo function_graph > current_tracer
# cat trace

0) | free_to_partial_list() {
0) | arch_stack_walk() {
0) | __unwind_start() {

-Wenum-enum-conversion was strengthened in clang-19 to warn for C, which
caused the kernel to move it to W=1 in commit 75b5ab134bb5 ("kbuild:
Move -Wenum-{compare-conditional,enum-conversion} into W=1") because
there were numerous instances that would break builds with -Werror.
Unfortunately, this is not a full solution, as more and more developers,
subsystems, and distributors are building with W=1 as well, so they
continue to see the numerous instances of this warning.
Since the move to W=1, there have not been many new instances that have
appeared through various build reports and the ones that have appeared
seem to be following similar existing patterns, suggesting that most
instances of this warning will not be real issues. The only alternatives
for silencing this warning are adding casts (which is generally seen as
an ugly practice) or refactoring the enums to macro defines or a unified
enum (which may be undesirable because of type safety in other parts of
the code).
Move the warning to W=2, where warnings that occur frequently but may be
relevant should reside.

While attempting to build a Debian packages with CC="ccache gcc", I
saw the following error as builddeb builds linux-headers-$KERNELVERSION:
make HOSTCC=ccache gcc VPATH= srcroot=. -f ./scripts/Makefile.build obj=debian/linux-headers-6.14.0-rc1/usr/src/linux-headers-6.14.0-rc1/scripts
make[6]: *** No rule to make target 'gcc'. Stop.
Upon investigation, it seems that one instance of $(CC) variable reference
in ./scripts/package/install-extmod-build was missing quotation marks,
causing the above error.
Add the missing quotation marks around $(CC) to fix build.

Pull vfs fixes from Christian Brauner:
- Fix fsnotify FMODE_NONOTIFY* handling.
This also disables fsnotify on all pseudo files by default apart from
very select exceptions. This carries a regression risk so we need to
watch out and adapt accordingly. However, it is overall a significant
improvement over the current status quo where every rando file can
get fsnotify enabled.
- Cleanup and simplify lockref_init() after recent lockref changes.
- Fix vboxfs build with gcc-15.
- Add an assert into inode_set_cached_link() to catch corrupt links.
- Allow users to also use an empty string check to detect whether a
given mount option string was empty or not.
- Fix how security options were appended to statmount()'s ->mnt_opt
field.
- Fix statmount() selftests to always check the returned mask.
- Fix uninitialized value in vfs_statx_path().
- Fix pidfs_ioctl() sanity checks to guard against ioctl() overloading
and preserve extensibility.
* tag 'vfs-6.14-rc2.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:

fixes performance issues when the filesystem is nearly full and
we're bottlenecked on copygc

be off when devices are being onlined/offlined; users should report
