Since commit ce6cb8113c84 ("tools: ynl-gen: individually free previous
values on double set"), specifying the "multi-attr" property raises an
error unless the "nested-attributes" property is specified as well:
File "tools/net/ynl/./pyynl/ynl_gen_c.py", line 1147, in _load_nested_sets
child = self.pure_nested_structs.get(nested)
^^^^^^
UnboundLocalError: cannot access local variable 'nested' where it is not associated with a value
This appears to be a bug since there are existing specs which omit
"nested-attributes" on "multi-attr" attributes. Also, according to
Documentation/userspace-api/netlink/specs.rst, multi-attr "is the
recommended way of implementing arrays (no extra nesting)", suggesting
that nesting should even be avoided in favor of multi-attr.
Fix the indentation of the if-block introduced by the commit to avoid
the error.

Pull probes fixes from Masami Hiramatsu:
- fprobe: Fix RCU warning message in list traversal
fprobe_module_callback() using hlist_for_each_entry_rcu() traverse
the fprobe list but it locks fprobe_mutex() instead of rcu lock
because it is enough. So add lockdep_is_held() to avoid warning.
- tracing: eprobe: Add missing trace_probe_log_clear for eprobe
__trace_eprobe_create() uses trace_probe_log but forgot to clear it
at exit. Add trace_probe_log_clear() calls.
- tracing: probes: Fix possible race in trace_probe_log APIs
trace_probe_log APIs are used in probe event (dynamic_events,
kprobe_events and uprobe_events) creation. Only dynamic_events uses
the dyn_event_ops_mutex mutex to serialize it. This makes kprobe and
uprobe events to lock the same mutex to serialize its creation to
avoid race in trace_probe_log APIs.

When bridged ports and standalone ports share a VLAN, e.g. via VLAN
uppers, or untagged traffic with a vlan unaware bridge, the ASIC will
still try to forward traffic to known FDB entries on standalone ports.
But since the port VLAN masks prevent forwarding to bridged ports, this
traffic will be dropped.
This e.g. can be observed in the bridge_vlan_unaware ping tests, where
this breaks pinging with learning on.
Work around this by enabling the simplified EAP mode on switches
supporting it for standalone ports, which causes the ASIC to redirect
traffic of unknown source MAC addresses to the CPU port.
Since standalone ports do not learn, there are no known source MAC
addresses, so effectively this redirects all incoming traffic to the CPU
port.

Since the shared trace_probe_log variable can be accessed and
modified via probe event create operation of kprobe_events,
uprobe_events, and dynamic_events, it should be protected.
In the dynamic_events, all operations are serialized by
`dyn_event_ops_mutex`. But kprobe_events and uprobe_events
interfaces are not serialized.
To solve this issue, introduces dyn_event_create(), which runs
create() operation under the mutex, for kprobe_events and
uprobe_events. This also uses lockdep to check the mutex is
held when using trace_probe_log* APIs.

Oleksij Rempel says:
====================
address EEE regressions on KSZ switches since v6.9 (v6.14+)
This patch series addresses a regression in Energy Efficient Ethernet
(EEE) handling for KSZ switches with integrated PHYs, introduced in
kernel v6.9 by commit fe0d4fd9285e ("net: phy: Keep track of EEE
configuration").
The first patch updates the DSA driver to allow phylink to properly
manage PHY EEE configuration. Since integrated PHYs handle LPI
internally and ports without integrated PHYs do not document MAC-level
LPI support, dummy MAC LPI callbacks are provided.
The second patch removes outdated EEE workarounds from the micrel PHY
driver, as they are no longer needed with correct phylink handling.
This series addresses the regression for mainline and kernels starting
from v6.14. It is not easily possible to fully fix older kernels due
to missing infrastructure changes.
Tested on KSZ9893 hardware.

The KSZ9477 PHY driver contained workarounds for broken EEE capability
advertisements by manually masking supported EEE modes and forcibly
disabling EEE if MICREL_NO_EEE was set.
With proper MAC-side EEE handling implemented via phylink, these quirks
are no longer necessary. Remove MICREL_NO_EEE handling and the use of
ksz9477_get_features().
This simplifies the PHY driver and avoids duplicated EEE management logic.

Phylink expects MAC drivers to provide LPI callbacks to properly manage
Energy Efficient Ethernet (EEE) configuration. On KSZ switches with
integrated PHYs, LPI is internally handled by hardware, while ports
without integrated PHYs have no documented MAC-level LPI support.
Provide dummy mac_disable_tx_lpi() and mac_enable_tx_lpi() callbacks to
satisfy phylink requirements. Also, set default EEE capabilities during
phylink initialization where applicable.
Since phylink can now gracefully handle optional EEE configuration,
remove the need for the MICREL_NO_EEE PHY flag.
This change addresses issues caused by incomplete EEE refactoring
introduced in commit fe0d4fd9285e ("net: phy: Keep track of EEE
configuration"). It is not easily possible to fix all older kernels, but
this patch ensures proper behavior on latest kernels and can be
considered for backporting to stable kernels starting from v6.14.

It has been reported that when under a bridge with stp_state=1, the logs
get spammed with this message:
[ 251.734607] fsl_dpaa2_eth dpni.5 eth0: Couldn't decode source port
Further debugging shows the following info associated with packets:
source_port=-1, switch_id=-1, vid=-1, vbid=1
In other words, they are data plane packets which are supposed to be
decoded by dsa_tag_8021q_find_port_by_vbid(), but the latter (correctly)
refuses to do so, because no switch port is currently in
BR_STATE_LEARNING or BR_STATE_FORWARDING - so the packet is effectively
unexpected.
The error goes away after the port progresses to BR_STATE_LEARNING in 15
seconds (the default forward_time of the bridge), because then,
dsa_tag_8021q_find_port_by_vbid() can correctly associate the data plane
packets with a plausible bridge port in a plausible STP state.
Re-reading IEEE 802.1D-1990, I see the following:
"4.4.2 Learning: (...) The Forwarding Process shall discard received
frames."
IEEE 802.1D-2004 further clarifies:
"DISABLED, BLOCKING, LISTENING, and BROKEN all correspond to the
DISCARDING port state. While those dot1dStpPortStates serve to
distinguish reasons for discarding frames, the operation of the
Forwarding and Learning processes is the same for all of them. (...)
LISTENING represents a port that the spanning tree algorithm has
selected to be part of the active topology (computing a Root Port or
Designated Port role) but is temporarily discarding frames to guard
against loops or incorrect learning."
Well, this is not what the driver does - instead it sets
mac[port].ingress = true.
To get rid of the log spam, prevent unexpected data plane packets to
be received by software by discarding them on ingress in the LISTENING
state.
In terms of blame attribution: the prints only date back to commit
d7f9787a763f ("net: dsa: tag_8021q: add support for imprecise RX based
on the VBID"). However, the settings would permit a LISTENING port to
forward to a FORWARDING port, and the standard suggests that's not OK.

__netdev_update_features() expects the netdevice to be ops-locked, but
it gets called recursively on the lower level netdevices to sync their
features, and nothing locks those.
This commit fixes that, with the assumption that it shouldn't be possible
for both higher-level and lover-level netdevices to require the instance
lock, because that would lead to lock dependency warnings.
Without this, playing with higher level (e.g. vxlan) netdevices on top
of netdevices with instance locking enabled can run into issues:

There is a situation where after THALT is set high, TGO stays high as
well. Because jiffies are never updated, as we are in a context with
interrupts disabled, we never exit that loop and have a deadlock.
That deadlock was noticed on a sama5d4 device that stayed locked for days.
Use retries instead of jiffies so that the timeout really works and we do
not have a deadlock anymore.

If btrfs_reserve_extent() fails while submitting an async_extent for a
compressed write, then we fail to call free_async_extent_pages() on the
async_extent and leak its folios. A likely cause for such a failure
would be btrfs_reserve_extent() failing to find a large enough
contiguous free extent for the compressed extent.
I was able to reproduce this by:
1. mount with compress-force=zstd:3
2. fallocating most of a filesystem to a big file
3. fragmenting the remaining free space
4. trying to copy in a file which zstd would generate large compressed
extents for (vmlinux worked well for this)
Step 4. hits the memory leak and can be repeated ad nauseam to
eventually exhaust the system memory.
Fix this by detecting the case where we fallback to uncompressed
submission for a compressed async_extent and ensuring that we call
free_async_extent_pages().

If the discard worker is running and there's currently only one block
group, that block group is a data block group, it's in the unused block
groups discard list and is being used (it got an extent allocated from it
after becoming unused), the worker can end up in an infinite loop if a
transaction abort happens or the async discard is disabled (during remount
or unmount for example).
This happens like this:
1) Task A, the discard worker, is at peek_discard_list() and
find_next_block_group() returns block group X;
2) Block group X is in the unused block groups discard list (its discard
index is BTRFS_DISCARD_INDEX_UNUSED) since at some point in the past
it become an unused block group and was added to that list, but then
later it got an extent allocated from it, so its ->used counter is not
zero anymore;
3) The current transaction is aborted by task B and we end up at
__btrfs_handle_fs_error() in the transaction abort path, where we call
btrfs_discard_stop(), which clears BTRFS_FS_DISCARD_RUNNING from
fs_info, and then at __btrfs_handle_fs_error() we set the fs to RO mode
(setting SB_RDONLY in the super block's s_flags field);
4) Task A calls __add_to_discard_list() with the goal of moving the block
group from the unused block groups discard list into another discard
list, but at __add_to_discard_list() we end up doing nothing because
btrfs_run_discard_work() returns false, since the super block has
SB_RDONLY set in its flags and BTRFS_FS_DISCARD_RUNNING is not set
anymore in fs_info->flags. So block group X remains in the unused block
groups discard list;
5) Task A then does a goto into the 'again' label, calls
find_next_block_group() again we gets block group X again. Then it
repeats the previous steps over and over since there are not other
block groups in the discard lists and block group X is never moved
out of the unused block groups discard list since
btrfs_run_discard_work() keeps returning false and therefore
__add_to_discard_list() doesn't move block group X out of that discard
list.
When this happens we can get a soft lockup report like this:

Building the kernel with O= is affected by stale in-tree build artifacts.
So, if the source tree is not clean, Kbuild displays the following:
$ make ARCH=um O=build defconfig
make[1]: Entering directory '/.../linux/build'
***
*** The source tree is not clean, please run 'make ARCH=um mrproper'
*** in /.../linux
***
make[2]: *** [/.../linux/Makefile:673: outputmakefile] Error 1
make[1]: *** [/.../linux/Makefile:248: __sub-make] Error 2
make[1]: Leaving directory '/.../linux/build'
make: *** [Makefile:248: __sub-make] Error 2
Usually, running 'make mrproper' is sufficient for cleaning the source
tree for out-of-tree builds.
However, building UML generates build artifacts not only in arch/um/,
but also in the SUBARCH directory (i.e., arch/x86/). If in-tree stale
files remain under arch/x86/, Kbuild will reuse them instead of creating
new ones under the specified build directory.
This commit makes 'make ARCH=um clean' recurse into the SUBARCH directory.

Silencing the instances from typecheck.h is difficult because '= {}' is
not available in older but supported compilers and '= {0}' would cause
warnings about a literal 0 being treated as NULL. While it might be
possible to come up with a local hack to silence the warning for
clang-21+, it may not be worth it since -Wuninitialized will still
trigger if an uninitialized const variable is actually used.
In all audited cases of the "field" variant of the warning, the members
are either not used in the particular call path, modified through other
means such as memset() / memcpy() because the containing object is not
const, or are within a union with other non-const members.
Since this warning does not appear to have a high signal to noise ratio,
just disable it.

With CONFIG_GENDWARFKSYMS, __gendwarfksyms_ptr variables are
added to the kernel in EXPORT_SYMBOL() to ensure DWARF type
information is available for exported symbols in the TUs where
they're actually exported. These symbols are dropped when linking
vmlinux, but dangling references to them remain in DWARF.
With CONFIG_DEBUG_INFO_BTF enabled on X86, pahole versions after
commit 47dcb534e253 ("btf_encoder: Stop indexing symbols for
VARs") and before commit 9810758003ce ("btf_encoder: Verify 0
address DWARF variables are in ELF section") place these symbols
in the .data..percpu section, which results in an "Invalid
offset" error in btf_datasec_check_meta() during boot, as all
the variables are at zero offset and have non-zero size. If
CONFIG_DEBUG_INFO_BTF_MODULES is enabled, this also results in a
failure to load modules with:
failed to validate module [$module] BTF: -22
As the issue occurs in pahole v1.28 and the fix was merged
after v1.29 was released, require pahole <v1.28 or >v1.29 when
GENDWARFKSYMS is enabled with DEBUG_INFO_BTF on X86.

Pull x86 ITS mitigation from Dave Hansen:
"Mitigate Indirect Target Selection (ITS) issue.
I'd describe this one as a good old CPU bug where the behavior is
_obviously_ wrong, but since it just results in bad predictions it
wasn't wrong enough to notice. Well, the researchers noticed and also
realized that thus bug undermined a bunch of existing indirect branch
mitigations.
Thus the unusually wide impact on this one. Details:
ITS is a bug in some Intel CPUs that affects indirect branches
including RETs in the first half of a cacheline. Due to ITS such
branches may get wrongly predicted to a target of (direct or indirect)
branch that is located in the second half of a cacheline. Researchers
at VUSec found this behavior and reported to Intel.
Affected processors:
- Cascade Lake, Cooper Lake, Whiskey Lake V, Coffee Lake R, Comet
Lake, Ice Lake, Tiger Lake and Rocket Lake.
Scope of impact:
- Guest/host isolation:
When eIBRS is used for guest/host isolation, the indirect branches
in the VMM may still be predicted with targets corresponding to
direct branches in the guest.
- Intra-mode using cBPF:
cBPF can be used to poison the branch history to exploit ITS.
Realigning the indirect branches and RETs mitigates this attack
vector.
- User/kernel:
With eIBRS enabled user/kernel isolation is *not* impacted by ITS.
- Indirect Branch Prediction Barrier (IBPB):
Due to this bug indirect branches may be predicted with targets
corresponding to direct branches which were executed prior to IBPB.
This will be fixed in the microcode.
Mitigation:
As indirect branches in the first half of cacheline are affected, the
mitigation is to replace those indirect branches with a call to thunk that
is aligned to the second half of the cacheline.
RETs that take prediction from RSB are not affected, but they may be
affected by RSB-underflow condition. So, RETs in the first half of
cacheline are also patched to a return thunk that executes the RET aligned
to second half of cacheline"

Pull x86 IBTI mitigation from Dave Hansen:
"Mitigate Intra-mode Branch History Injection via classic BFP programs
This adds the branch history clearing mitigation to cBPF programs for
x86. Intra-mode BHI attacks via cBPF a.k.a IBTI-History was reported
by researchers at VUSec.
For hardware that doesn't support BHI_DIS_S, the recommended
mitigation is to run the short software sequence followed by the IBHF
instruction after cBPF execution. On hardware that does support
BHI_DIS_S, enable BHI_DIS_S and execute the IBHF after cBPF execution.
The Indirect Branch History Fence (IBHF) is a new instruction that
prevents indirect branch target predictions after the barrier from
using branch history from before the barrier while BHI_DIS_S is
enabled. On older systems this will map to a NOP. It is recommended to
add this fence at the end of the cBPF program to support VM migration.
This instruction is required on newer parts with BHI_NO to fully
mitigate against these attacks.
The current code disables the mitigation for anything running with the
SYS_ADMIN capability bit set. The intention was not to waste time
mitigating a process that has access to anything it wants anyway"

RISC-V:
- Add missing reset of smstateen CSRs

- Forcibly leave SMM on SHUTDOWN interception on AMD CPUs to avoid
causing problems due to KVM stuffing INIT on SHUTDOWN (KVM needs to
sanitize the VMCB as its state is undefined after SHUTDOWN,
emulating INIT is the least awful choice).
- Track the valid sync/dirty fields in kvm_run as a u64 to ensure KVM
KVM doesn't goof a sanity check in the future.
- Free obsolete roots when (re)loading the MMU to fix a bug where
pre-faulting memory can get stuck due to always encountering a
stale root.
- When dumping GHCB state, use KVM's snapshot instead of the raw GHCB
page to print state, so that KVM doesn't print stale/wrong
information.
- When changing memory attributes (e.g. shared <=> private), add
potential hugepage ranges to the mmu_invalidate_range_{start,end}
set so that KVM doesn't create a shared/private hugepage when the
the corresponding attributes will become mixed (the attributes are
commited *after* KVM finishes the invalidation).

The Share button, if present, is always one of two offsets from the end of the
file, depending on the presence of a specific interface. As we lack parsing for
the identify packet we can't automatically determine the presence of that
interface, but we can hardcode which of these offsets is correct for a given
controller.
More controllers are probably fixable by adding the MAP_SHARE_BUTTON in the
future, but for now I only added the ones that I have the ability to test
directly.

Two controllers -- Mad Catz JOYTECH NEO SE Advanced and PDP Mirror's
Edge Official -- were missing the value of the mapping field, and thus
wouldn't detect properly.

To wake up the system from s2idle when pressing the power-button, let's
convert from using pm_wakeup_event() to pm_wakeup_dev_event(), as it allows
us to specify the "hard" in-parameter, which needs to be set for s2idle.
