This patch continues the effort to refactor workqueue APIs, which has begun
with the changes introducing new workqueues and a new alloc_workqueue flag:
commit 128ea9f6cc ("workqueue: Add system_percpu_wq and system_dfl_wq")
commit 930c2ea566 ("workqueue: Add new WQ_PERCPU flag")
The point of the refactoring is to eventually alter the default behavior of
workqueues to become unbound by default so that their workload placement is
optimized by the scheduler.
Before that to happen after a careful review and conversion of each individual
case, workqueue users must be converted to the better named new workqueues with
no intended behaviour changes:
system_wq -> system_percpu_wq
system_unbound_wq -> systemd_dfl_wq
This way the old obsolete workqueues (system_wq, system_unbound_wq) can be
removed in the future.

Currently if a user enqueues a work item using schedule_delayed_work() the
used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use
WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to
schedule_work() that is using system_wq and queue_work(), that makes use
again of WORK_CPU_UNBOUND.
This lack of consistency cannot be addressed without refactoring the API.

alloc_workqueue() treats all queues as per-CPU by default, while unbound
workqueues must opt-in via WQ_UNBOUND.
This default is suboptimal: most workloads benefit from unbound queues,
allowing the scheduler to place worker threads where they’re needed and
reducing noise when CPUs are isolated.

This change adds a new WQ_PERCPU flag to explicitly request
alloc_workqueue() to be per-cpu when WQ_UNBOUND has not been specified.
With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND),
any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND
must now use WQ_PERCPU.
Once migration is complete, WQ_UNBOUND can be removed and unbound will

In the wpa_supplicant rekey flow, it sends an EAPOL packet 4/4 through
nl80211_tx_control_port() and triggers wake_tx_queue() in the driver.
Then, it sends nl80211_new_key() to configure a new key in mac80211.
However, in wake_tx_queue(), a workqueue is used to process the TX packet,
which might cause the driver to process the EAPOL packet later than
nl80211_new_key(). This results in the EAPOL packet 4/4 being transmitted
with the new key and IV, causing it to be dropped by the AP. Therefore,
needs to flush TX queue before deleting the old key to ensure that the
EAPOL 4/4 packet is transmitted using the old key.

hsr: Send correct HSRv0 supervision frames
Hangbin recently reported that the hsr selftests were failing and noted
that the entries in the node table were not merged, i.e., had
00:00:00:00:00:00 as MacAddressB forever [1].
This failure only occured with HSRv0 because it was not sending
supervision frames anymore. While debugging this I found that we were
not really following the HSRv0 standard for the supervision frames we
sent, so I additionally made a few changes to get closer to the standard
and restore a more correct behavior we had a while ago.
The selftests can still fail because they take a while and run into the
timeout. I did not include a change of the timeout because I have more
improvements to the selftests mostly ready that change the test duration
but are net-next material.

For HSRv0, the path_id has the following meaning:
- 0000: PRP supervision frame
- 0001-1001: HSR ring identifier
- 1010-1011: Frames from PRP network (A/B, with RedBoxes)
- 1111: HSR supervision frame
Follow the IEC 62439-3:2010 standard more closely by setting the right
path_id for HSRv0 supervision frames (actually, it is correctly set when
the frame is constructed, but hsr_set_path_id() overwrites it) and set a
fixed HSR ring identifier of 1. The ring identifier seems to be generally
unused and we ignore it anyways on reception, but some fixed identifier is
definitely better than using one identifier in one direction and a wrong
identifier in the other.
This was also the behavior before commit f266a683a4 ("net/hsr: Better
frame dispatch") which introduced the alternating path_id. This was later
moved to hsr_set_path_id() in commit 451d8123f8 ("net: prp: add packet
handling support").
The IEC 62439-3:2010 also contains 6 unused bytes after the MacAddressA in
the HSRv0 supervision frames. Adjust a TODO comment accordingly.

On HSRv0, no supervision frames were sent. The supervison frames were
generated successfully, but failed the check for a sufficiently long mac
header, i.e., at least sizeof(struct hsr_ethhdr), in hsr_fill_frame_info()
because the mac header only contained the ethernet header.
Fix this by including the HSR header in the mac header when generating HSR
supervision frames. Note that the mac header now also includes the TLV
fields. This matches how we set the headers on rx and also the size of
struct hsrv0_ethhdr_sp.

The purpose of commit 703eec1b24 ("virtio_net: fixing XDP for fully
checksummed packets handling") is to record the flags in advance, as
their value may be overwritten in the XDP case. However, the flags
recorded under big mode are incorrect, because in big mode, the passed
buf does not point to the rx buffer, but rather to the page of the
submitted buffer. This commit fixes this issue.
For the small mode, the commit c11a49d58a ("virtio_net: Fix mismatched
buf address when unmapping for small packets") fixed it.

====================
pull-request: can-next 2025-11-12
this is a pull request of 11 patches for net-next/main.
The first 3 patches are by Vadim Fedorenko and convert the CAN drivers
to use the ndo_hwtstamp callbacks.
Maud Spierings contributes a patch for the mcp251x driver that
converts it to use dev_err_probe().
The next 6 patches target the mcp251xfd driver and are by Gregor
Herburger and me. They add GPIO controller functionality to the
driver.
The final patch is by Chu Guangqing and fixes a typo in the bxcan
driver.

net: stmmac: convert glue drivers to use stmmac_get_phy_intf_sel()
This series converts the remaining glue drivers that support
multi-interface to use stmmac_get_phy_intf_sel(). The reason these
drivers are not converted to the set_phy_intf_sel() method is
because it is unclear whether there are ordering dependencies that
would prevent it.
For example, reading the stm32mp2 documentation, it is required to
set the ETH1_SEL field while the dwmac core is in reset and before
clocks are enabled. This requirement can not be satsified at the
moment (but could with further changes.)

Use stmmac_get_phy_intf_sel() to decode the PHY interface mode to the
phy_intf_sel value, validate the result and use that to set the
control register to select the operating mode for the DWMAC core.
Note that this will allow GMII as well as MII as the phy_intf_sel
value is the same for both.

Convert dwmac-visconti to use the PHY_INTF_SEL_x definitions. The
original definitions used constant 0, BIT(0) (==1) and BIT(2) (==4)
to define these, but the values of the bits corresponds with the
PHY_INTF_SEL_x values, so it is highly likely that these are not
individual bits, but the PHY_INTF_SEL_x bitfield.
This removes this incorrect use of BIT().

Use stmmac_get_phy_intf_sel() to decode the PHY interface mode to the
phy_intf_sel value. As both configure functions would end up with the
same code, call this from stm32mp1_set_mode(), validate the result and
pass the resulting value into the stm32 configure function. Use this
value to set the operating mode for the DWMAC core.

Rather than defining separate constants for each, use the
PHY_INTF_SEL_x definitions in the switch()es configuring the
control register, and use one FIELD_PREP() to convert phy_intf_sel
to the register value.

Convert dwmac-stm32 to use the PHY_INTF_SEL_x definitions.
For stm32mp1, the original definitions used constant 0 (GMII, 0 << 21),
BIT(21) (RGMII, 1 << 21) and BIT(23) (RMII, 4 << 21) to define these,
but from the values it can be clearly seen that these are the
PHY_INTF_SEL_x inputs to the dwmac.
For stm32mp2, the original definitions cover a bitfield 6:4 in the
SYSCFG Ethernet1 control register (according to documentation) and use
the PHY_INTF_SEL_x values.
Use the common dwmac definitions for the PHY interface selection field
by adding the bitfield mask, and using FIELD_PREP() for the bitfield
values.
This removes this incorrect use of BIT().
