It is illegal to schedule reset work from another reset work!
Fix this by scheduling the userq reset work directly on the work queue
of the reset domain.
Not fully tested, I leave that to the IGT test cases.

Since commit
5894cf571e14 ("acpi/prmt: Use EFI runtime sandbox to invoke PRM handlers")
ACPI PRM calls are delegated to a workqueue which runs in a kernel
thread, making it easier to detect and mitigate faulting memory accesses
performed by the firmware.
Rafael reports that such PRM accesses may occur before efisubsys_init()
executes, which is where the workqueue is allocated, leading to NULL
pointer dereferences. Since acpi_init() [which triggers the early PRM
accesses] executes as a subsys_initcall() as well, and has its own
dependencies that may be sensitive to initcall ordering, deferring
acpi_init() is not an option.
So instead, split off the workqueue allocation into its own postcore
initcall, as this is the only missing piece to allow EFI runtime calls
to be made. This ensures that EFI runtime call (including PRM calls) are
accessible to all code running at subsys_initcall() level.

The mini-LED current_value attribute does not work on devices that use
ASUS_WMI_DEVID_MINI_LED_MODE2 (2024 and newer models).
Reading is broken: mini_led_mode_current_value_show() fetches the mode
from the device but then decodes a literal 0 instead of the value it
just read:
mode = FIELD_GET(ASUS_MINI_LED_MODE_MASK, 0);
So mode is always 0, and the attribute always reports the same thing
regardless of the real hardware state.
Writing is broken too. The number a user writes is an index; the value
the firmware actually wants is looked up from that index in
mini_led_mode_map[]. mini_led_mode_current_value_store() skips that
lookup and passes the raw index straight to armoury_attr_uint_store().
On 2024 devices the firmware numbers its modes differently from the
index, so some writes are rejected with -EINVAL and the rest send the
wrong mode to the hardware.
Fix both paths: decode the value actually read from the device when
reading, and look up the firmware value before sending it when
writing. Older (MODE1) devices were unaffected because there the index
and the firmware value are the same.

After a PCIe Uncorrectable Error has been reported by a device with
Intel Vendor Specific Extended Capabilities and has been recovered
through a Secondary Bus Reset, its driver calls intel_vsec_pci_probe()
to rescan and reinitialize VSECs.
intel_vsec_pci_probe() invokes pcim_enable_device() and thereby adds
another devm action which calls pcim_disable_device() on driver unbind.
So once the driver unbinds, pcim_disable_device() will be called as many
times as an Uncorrectable Error occurred, plus one. This will lead to
an enable_cnt imbalance on driver unbind.
Additionally, since commit dc957ab6aa05 ("platform/x86/intel/vsec: Add
private data for per-device data"), a devm_kzalloc() allocation is
leaked on every Uncorrectable Error.
Avoid by splitting the VSEC rescan out of intel_vsec_pci_probe() into a
separate helper and calling that on PCIe error recovery.

pdsfc_fw_rpc() casts the buffer to struct fwctl_rpc_pds and then calls
pdsfc_validate_rpc(), which reads fields from that structure before

in_len can make pds_fwctl read beyond the allocation.

In mana_hwc_rx_event_handler(), resp->response.hwc_msg_id is read from
DMA-coherent memory and bounds-checked, then mana_hwc_handle_resp()
re-reads the same field from the same DMA buffer for test_bit() and
pointer arithmetic.
DMA-coherent memory is mapped uncacheable on x86 and is shared,
unencrypted, in Confidential VMs (SEV-SNP/TDX), so each load goes
directly to host-visible memory. A H/W can modify the value
between the check and the use, bypassing the bounds validation.
Fix this by reading hwc_msg_id exactly once using READ_ONCE() into a
stack-local variable in mana_hwc_rx_event_handler(), and passing the
validated value as a parameter to mana_hwc_handle_resp().

In i2c_smbus_xfer_emulated(), there are two buffers: msgbuf0 and
msgbuf1, which are used to save a series of messages, as mentioned in
the comment. According to the value of the variable 'size', msgbuf0 is
initialized to various values. In contrast, msgbuf1 is left
uninitialized until the function i2c_transfer() is invoked. However,
msgbuf1 is not always initialized on all possible execution paths
(implementation) of i2c_transfer(). Thus, it is possible that msgbuf1
may still be uninitialized even after the invocation of the function
i2c_transfer(), especially when the return value of i2c_transfer() is
not checked properly. In the following execution, the uninitialized
msgbuf1 will be used, such as for security checks. Since uninitialized
values can be random and arbitrary, this will cause undefined behaviors
or even check bypass. For example, it is expected that if the value of
'size' is I2C_SMBUS_BLOCK_PROC_CALL, the value of data->block[0] should
not be larger than I2C_SMBUS_BLOCK_MAX. This patch initializes the first
byte of msgbuf1 with 0 to avoid such undefined behaviors or security
issues.

With bridge VLAN filtering enabled on a port configured as untagged
member of the bridge PVID, ingress untagged frames do not reach the
corresponding bridge VLAN upper interface (br-lan.<vid>). ARP and
similar traffic is visible on the physical port but not delivered
to the VLAN sub-interface.
The MT7530/MT7531 forwards frames to the CPU port with the user
port's PVID tag applied even when the frame ingressed untagged on
the wire, because the CPU port is set to MT7530_VLAN_EG_CONSISTENT
and is a tagged member of the VLAN entry created for the bridge
VLAN. The DSA core then sees a hwaccel-tagged frame whose VID
matches the port's PVID, which the bridge does not treat as the
untagged-on-the-wire frame that the user expects.
Set ds->untag_vlan_aware_bridge_pvid in the mt7530 and mt7531
setup paths so the DSA core strips that hwaccel tag in software
when the parsed VID matches the bridge port's PVID, restoring the
on-the-wire frame as the bridge expects to see it.

After a VLAN-aware bridge is destroyed, creating any VLAN-unaware
bridge loses all connectivity. The VID 0 VLAN table entry used by
VLAN-unaware ports in FALLBACK mode gets corrupted during VLAN-aware
operation: mt7530_hw_vlan_add() overwrites its EG_CON flag with
VTAG_EN and bridge teardown removes ports from its PORT_MEM.
The cleanup code that should restore it never runs because the current
port's dp->vlan_filtering flag is still true when checked (DSA updates
it only after the driver callback returns). Even when restored, the
deferred VLAN deletion events from the switchdev workqueue can corrupt
VID 0 again after the restoration.
Skip the current port in the all_user_ports_removed check, call
mt7530_setup_vlan0() to restore the VID 0 entry, and protect VID 0
from being modified by bridge VLAN operations in port_vlan_add and
port_vlan_del since it is managed exclusively by mt7530_setup_vlan0().
Remove the CPU port PCR and PVC register writes which were clobbering
PORT_VLAN mode and VLAN_ATTR with wrong values.

The BPC, RGAC1 and RGAC2 registers control the handling of link-local
frames with reserved MAC DAs (01:80:C2:00:00:0x). These frames are
correctly trapped to the CPU port, but the egress VLAN tag attribute was
set to MT7530_VLAN_EG_UNTAGGED which causes the switch to strip any
VLAN tags from trapped frames before they reach the CPU.
This causes VLAN-tagged link-local frames (STP BPDUs, LLDP, PTP Peer
Delay Requests) to arrive at the CPU without their VLAN tag, so they
are delivered to the base network interface instead of the VLAN
sub-interface. The DSA local_termination selftest confirms this: all
link-local protocol tests on VLAN upper interfaces fail.
Set the EG_TAG attribute to MT7530_VLAN_EG_DISABLED (system default)
so that the switch does not modify VLAN tags in trapped frames. This
way VLAN-tagged frames retain their original tag and are delivered to
the correct VLAN sub-interface, matching the behavior of non-trapped
frames which pass through without VLAN tag modification.

The DSA forwarding selftests bridge_vlan_aware.sh and
bridge_vlan_unaware.sh configure the bridge with ageing_time set to
LOW_AGEING_TIME (1000 centiseconds, i.e. 10 seconds) and then run
learning_test() in lib.sh, which expects a learned FDB entry to be
removed after ageing_time + 10 seconds. On MT7530/MT7531 the entry
persisted past the deadline and the "Found FDB record when should
not" assertion failed.
With msecs=10000, the algorithm in mt7530_set_ageing_time() finds
AGE_CNT=0 and AGE_UNIT=9 as the first exact match (starting the
search from tmp_age_count=0). The per-entry aging counter is
initialized to AGE_CNT when a MAC address is learned, so with
AGE_CNT=0 new entries start with a counter value of 0, which the
hardware treats as "already aged" and never removes, effectively
disabling aging.
Fix this by starting the search from tmp_age_count=1 to ensure
entries always have a non-zero initial aging counter. For a
10-second ageing time this yields AGE_CNT=1 and AGE_UNIT=4 instead:
the timer ticks every 5 seconds and entries are removed after 2
ticks.
Starting the search at AGE_CNT=1 raises the minimum representable
ageing time from 1 to 2 seconds. Without bounds, a stale ageing_time
of 1 second would now make the loop fall through without setting
age_count and age_unit, leaving them uninitialized when written to
the MT7530_AAC hardware register. Set ds->ageing_time_min and
ds->ageing_time_max so the DSA core validates the range before the
callback is invoked, and drop the now-redundant range check from
mt7530_set_ageing_time().

Keep drm_bridge_add() rather than devm_drm_bridge_add(): registration is
tied to the STDP4028 device while ge_b850v3_register() may complete from
either I2C probe; devm would not unwind the bridge if the other client's

EDP specification says:
"If either VSC SDP is unable to be transmitted 100 ns before the SU region,
the Source device may optionally transmit the VSC SDP during the prior
video scan line’s HBlank period There is a Intel specific drm dp register
currently containing bits related how TCON can support PSR2 with SDP on
prior line."
Unfortunately many panels are having problems in implementing this. So
there is a custom Intel specific DPCD register (INTEL_WA_REGISTER_CAPS) to
figure out if this is properly implemented on a panel or if panel doesn't
require that 100 ns delay before the SU region. Here are the definitions in
this custom DPCD address:
0 = Panel doesn't support SDP on prior line
1 = Panel supports SDP on prior line
2 = Panel doesn't have 100ns requirement
3 = Reserved
Add definitions for this new register and it's values into new header

ixgbevf_clean_rx_irq() prunes frames whose source MAC matches the VF's
own address (VEPA multicast workaround) by freeing the skb and
continuing to the next descriptor:
dev_kfree_skb_irq(skb);
continue;
The skb pointer is declared outside the while loop and persists across
iterations. Because the continue skips the "skb = NULL" reset at the
bottom of the loop, the next iteration enters the "else if (skb)" path
and calls ixgbevf_add_rx_frag() on the freed skb, dereferencing
skb_shinfo(skb)->nr_frags - a use-after-free in NAPI softirq context.
The sibling driver iavf already handles this correctly by nulling the
pointer before continuing. Apply the same pattern here.
I do not have ixgbevf hardware; the bug was found by static analysis
(scan_drop_continue_loops.py + semgrep drop_continue_in_loop, multi-tool
corroboration with the highest score in the scan). The UAF was confirmed
under KASAN by loading a test module that reproduces the exact code
pattern (alloc skb, kfree_skb, then read skb_shinfo(skb)->nr_frags):
BUG: KASAN: slab-use-after-free in ixgbevf_uaf_test_init+0x100/0x1000

freed 208-byte region [000000006163adc0, 000000006163ae90)
QEMU emulates igb (82576) but not ixgbe (82599), and the igbvf VF
driver does not include the VEPA source pruning path, so a full
end-to-end reproduction with emulated hardware was not possible.

When ethtool -L changes queue counts, ice_vsi_recfg_qs() closes and
rebuilds the VSI, reallocating Rx rings. The newly allocated rings have
ptp_rx cleared, so RX hardware timestamps are no longer attached to skb
until hwtstamp configuration is applied again.
Restore timestamp mode after ice_vsi_open() in the queue reconfiguration
path, matching reset/rebuild behavior and ensuring newly rebuilt Rx rings
have PTP RX timestamping re-enabled.
Testing hints:
- run ptp4l application in client synchronization mode:
ptp4l -i ethX -m -s
- run PTP traffic
- change queue number on ethX netdev interface:
ethtool -L ethX combined new_queue_size
- observe ptp4l output
- expected result: no "received DELAY_REQ without timestamp" messages

For E825 2xNAC configurations, PTP semaphore operations must hit the
primary NAC register block so both sides coordinate on the same lock.
Commit e2193f9f9ec9 ("ice: enable timesync operation on 2xNAC E825
devices") updated other primary-only PTP register accesses to
use the primary NAC on non-primary functions, but left ice_ptp_lock()
and ice_ptp_unlock() operating on the local NAC. As a result, secondary
NAC PTP paths can take a different semaphore than the primary side.
Select the primary hardware in ice_ptp_lock() and ice_ptp_unlock() when
the current function is not primary, keeping semaphore operations
symmetric and consistent with the rest of the 2xNAC PTP register access
path.

ice_start_phy_timer_eth56g() programs TIMETUS registers and issues
INIT_INCVAL without holding the global PTP semaphore.
This allows concurrent PTP command paths to interleave with PHY timer
start, which can make the sequence fail and leave timer initialization
inconsistent.
Take the PTP lock around TIMETUS registers programming and INIT_INCVAL
command execution, and make sure the lock is released on all error paths.
Keep the subsequent sync step outside of this critical section, since
ice_sync_phy_timer_eth56g() takes the same semaphore internally.

There are at least two paths through which VSI promiscuous mode can be
independently configured via ice_fltr_set_vsi_promisc():
- ice_vlan_rx_add_vid() (netdev op)
- ice_service_task() -> ... -> ice_set_promisc()
Both paths may try to program promiscuous mode concurrently. One such
scenario is:
1. Add ice netdev to bond
2. Add the bond netdev to bridge
3. ice netdev enters allmulticast mode (IFF_ALLMULTI)
4. Service task programs promisc mode filter
5. Bridge -> bond calls ice_vlan_rx_add_vid()
Crucially, ice_vlan_rx_add_vid() fails if ice_fltr_set_vsi_promisc()
returns any error, including -EEXIST. This causes VLAN filtering setup
to fail on the bond interface. ice_set_promisc() already handles -EEXIST
correctly.
Fix by adding the same -EEXIST check to ice_vlan_rx_add_vid(): if the
promisc filter is already programmed, continue without returning error.

The ice driver's VF queue configuration validation rejects
databuffer_size values below 1024 bytes, which prevents VFs from
using MTU values below 871 bytes.
The iavf driver calculates databuffer_size based on the MTU using:
databuffer_size = ALIGN(MTU + LIBETH_RX_LL_LEN, 128)
where LIBETH_RX_LL_LEN = 26 (ETH_HLEN + 2*VLAN_HLEN + ETH_FCS_LEN).
For MTU values below 871:
MTU 870: 870 + 26 = 896, aligned to 128 = 896 (< 1024, rejected)
MTU 871: 871 + 26 = 897, aligned to 128 = 1024 (>= 1024, accepted)
The 1024-byte minimum seems unnecessarily restrictive, because the hardware
supports databuffer_size as low as 128 bytes (the alignment boundary),
which should allow MTU values down to the standard minimum of 68 bytes.
I haven't found the reason why the limit was configured in the commit
9c7dd7566d18 ("ice: add validation in OP_CONFIG_VSI_QUEUES VF message"), so
with no more information and since it is working, change the minimum
databuffer_size validation from 1024 to 128 bytes to allow standard low
MTU values while still preventing invalid configurations.
