wifi: cfg80211: replace use of system_unbound_wq with system_dfl_wq
Currently if a user enqueues a work item using schedule_delayed_work() the

WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to

again of WORK_CPU_UNBOUND.
This lack of consistency cannot be addressed without refactoring the API.

the ->setup() method to initialise when it is provided. Rename this
method to "mac_setup" to more accurately describe what it is doing.
stmmac_reset() takes the stmmac_priv and an ioaddr. It has one call
site, which passes the priv pointer, and dereferences priv for the
ioaddr.
stmmac_reset() then checks whether priv is NULL. If it was, the caller
would have oopsed. Remove the checks for NULL, and move the dereference
for ioaddr into stmmac_reset().
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.

hsr: Follow standard for HSRv0 supervision frames
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 f266a683a480 ("net/hsr: Better
frame dispatch") which introduced the alternating path_id. This was later
moved to hsr_set_path_id() in commit 451d8123f897 ("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.

hsr: Fix supervision frame sending on HSRv0
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.

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 c11a49d58ad2 ("virtio_net: Fix mismatched

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.)
====================
net: stmmac: visconti: use stmmac_get_phy_intf_sel()
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.
net: stmmac: visconti: use PHY_INTF_SEL_x to select PHY interface
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.
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.
net: stmmac: stm32: use PHY_INTF_SEL_x to select PHY interface
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.
net: stmmac: starfive: use stmmac_get_phy_intf_sel()
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.
net: stmmac: mediatek: use stmmac_get_phy_intf_sel()
Use stmmac_get_phy_intf_sel() to decode the PHY interface mode to the
phy_intf_sel value, validate the result, and pass that into the
implementation specific ->dwmac_set_phy_interface() method. Use this
to configure the PHY interface selection field.
net: stmmac: loongson1: use stmmac_get_phy_intf_sel()
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.
Use PHY_INTF_SEL_x definitions for phy_intf_sel bitfield.

selftests: drv-net: Limit the max number of queues in procfs_downup_hammer
For NICs with a large (1024+) number of queues, this test can cause
excessive memory fragmentation. This results in OOM errors, and in the
worst case driver/kernel crashes. We don't need to test with the max number
of queues, just enough to create a high likelihood of races between
reconfiguration and stats getting read.
The mcp251xfd allows two pins to be configured as GPIOs. This series adds
support for this feature.
The GPIO functionality is controlled with the IOCON register which has an
erratum.
Patch 1 from https://lore.kernel.org/linux-can/20240429-mcp251xfd-runtime_pm-v1-3-c26a93a66544@pengutronix.de/
Patch 2 refactor of no-crc functions to prepare workaround for non-crc writes
Patch 3 is the fix/workaround for the aforementioned erratum
Patch 4 only configure pin1 for rx-int
Patch 5 adds the gpio support
Patch 6 updates dt-binding
can: mcp251xfd: only configure PIN1 when rx_int is set
When rx_int is used th mcp251xfd_chip_rx_int_enable and
mcp251xfd_chip_rx_int_disable function configure both PIN0 and PIN1. To
prepare the support of the GPIOS only configure PIN1 with
regmap_update_bits.
This way PIN0 can be used as GPIO while PIN1 is used as rx_int
interrupt.
According to Errata DS80000789E 5 writing IOCON register using one SPI
write command clears LAT0/LAT1.
Errata Fix/Work Around suggests to write registers with single byte write
instructions. However, it seems that every write to the second byte
causes the overwrite of LAT0/LAT1.
Never write byte 2 of IOCON register to avoid clearing of LAT0/LAT1.

on the hardware specific maximum defined by the MAC core, and also a
platform provided maximum.
The code was originally checking that the platform specific maximum was
between ndev->min_mtu..MAC core maximum before reducing ndev->max_mtu,
otherwise if the platform specific maximum was less than ndev->min_mtu,
issuing a warning.
Re-order the code to handle the case where the platform specific max is
below ndev->min_mtu, which then means that the subsequent test is
simply reducing ndev->max_mtu.
Update the comment, and add a few blank lines to separate the blocks of
code.

ipv4: route: Prevent rt_bind_exception() from rebinding stale fnhe
The sit driver's packet transmission path calls: sit_tunnel_xmit() ->
update_or_create_fnhe(), which lead to fnhe_remove_oldest() being called
to delete entries exceeding FNHE_RECLAIM_DEPTH+random.
The race window is between fnhe_remove_oldest() selecting fnheX for
deletion and the subsequent kfree_rcu(). During this time, the
concurrent path's __mkroute_output() -> find_exception() can fetch the
soon-to-be-deleted fnheX, and rt_bind_exception() then binds it with a
new dst using a dst_hold(). When the original fnheX is freed via RCU,
the dst reference remains permanently leaked.

"${KSFT_PASS}"` lines are reported as unreachable, even though they are
executed during normal runs. For SC2119, the fact that

selftests/vsock: speed up tests by reducing the QEMU pidfile timeout
Reduce the time waiting for the QEMU pidfile from three minutes to five
seconds. The three minute time window was chosen to make sure QEMU had
enough time to fully boot up. This, however, is an unreasonably long
delay for QEMU to write the pidfile, which happens earlier when the QEMU
process starts (not after VM boot). The three minute delay becomes
noticeably wasteful in future tests that expect QEMU to fail and wait a
full three minutes for a pidfile that will never exist.

selftests/vsock: avoid multi-VM pidfile collisions with QEMU
Change QEMU to use generated pidfile names instead of just a single
globally-defined pidfile. This allows multiple QEMU instances to
co-exist with different pidfiles. This is required for future tests that
use multiple VMs to check for CID collissions.
Additionally, this also places the burden of killing the QEMU process
and cleaning up the pidfile on the caller of vm_start(). To help with
this, a function terminate_pidfiles() is introduced that callers use to
perform the cleanup. The terminate_pidfiles() function supports multiple
pidfile removals because future patches will need to process two
pidfiles at a time.
Change QEMU_OPTS to be initialized inside the vm_start(). This allows
the generated pidfile to be passed to the string assignment, and

Remove log_setup() and instead use log_host(). The host/guest prefixes
are useful to show whether a failure happened on the guest or host side,
but "setup" doesn't really give additional useful information. Since all
log_setup() calls happen on the host, lets just use log_host() instead.

This is a preparation patch to add errata workaround for non crc writes.

To allow the addition of the errata fix at a single location use
mcp251xfd_regmap_nocrc_gather_write for all non-CRC write instructions,
similar to the crc regmap.

This is a preparation patch to add GPIO support.
Up to now, the Vdd regulator and the clocks have been managed by
Runtime-PM (on systems without CONFIG_PM these remain permanently
switched on).
During the mcp251xfd_open() callback the mcp251xfd is powered,
soft-reset and configured. In mcp251xfd_stop() the chip is shut down
again. To support the on-chip GPIOs, the chip must be supplied with
power while GPIOs are being requested, even if the networking
interface is down.
To support this, move the functions mcp251xfd_chip_softreset() and
mcp251xfd_chip_clock_init() from mcp251xfd_chip_start() to
mcp251xfd_runtime_resume(). Instead of setting the controller to sleep
mode in mcp251xfd_chip_stop(), bring it into configuration mode. This
way it doesn't take part in bus activity and doesn't enter sleep mode.

wifi: iwlwifi: mld: always take beacon ies in link grading
One of the factors of a link's grade is the channel load, which is
calculated from the AP's bss load element.
The current code takes this element from the beacon for an active link,
and from bss->ies for an inactive link.
bss->ies is set to either the beacon's ies or to the probe response
ones, with preference to the probe response (meaning that if there was
even one probe response, the ies of it will be stored in bss->ies and
won't be overiden by the beacon ies).
The probe response can be very old, i.e. from the connection time,
where a beacon is updated before each link selection (which is
triggered only after a passive scan).
In such case, the bss load element in the probe response will not
include the channel load caused by the STA, where the beacon will.
This will cause the inactive link to always have a lower channel
load, and therefore an higher grade than the active link's one.
This causes repeated link switches, causing the throughput to drop.
Fix this by always taking the ies from the beacon, as those are for
sure new.
During the development of the rate changes, I evidently made
some changes that shouldn't have been there; beacon templates
with rate_n_flags are only in old versions, so no changes to
them should have been necessary, and evidently broke on some
devices. This also would have broken fixed (injection) rates,
it would seem. Restore the old handling of this.

selftests: mptcp: connect: trunc: read all recv data
MPTCP Join "fastclose server" selftest is sometimes failing because the
client output file doesn't have the expected size, e.g. 296B instead of
1024B.
When looking at a packet trace when this happens, the server sent the
expected 1024B in two parts -- 100B, then 924B -- then the MP_FASTCLOSE.
It is then strange to see the client only receiving 296B, which would
mean it only got a part of the second packet. The problem is then not on
the networking side, but rather on the data reception side.
When mptcp_connect is launched with '-f -1', it means the connection
might stop before having sent everything, because a reset has been
received. When this happens, the program was directly stopped. But it is
also possible there are still some data to read, simply because the
previous 'read' step was done with a buffer smaller than the pending
data, see do_rnd_read(). In this case, it is important to read what's
left in the kernel buffers before stopping without error like before.
SIGPIPE is now ignored, not to quit the app before having read
everything.

reset instead of cleanly removed. This can happen when one extra subflow
which has never carried data is being closed (FIN) on one side, while

been a steady trickle of fixes and some of them took a few rounds of

The bulk of the changes are fixing some fallout from the recent BBM
level two support which allows the linear map to be split from block
to page mappings at runtime, but inadvertently led to sleeping in
atomic context on some paths where the linear map was already mapped
with page granularity. The fix is simply to avoid splitting in those
cases but the implementation of that is a little involved.
The other interesting fix is addressing a catastophic performance
issue with our per-cpu atomics discovered by Paul in the SRCU locking
code but which took some interactions with the hardware folks to
resolve.
Summary:
- Avoid sleeping in atomic context when changing linear map
permissions for DEBUG_PAGEALLOC or KFENCE
- Rework printing of Spectre mitigation status to avoid hardlockup
when enabling per-task mitigations on the context-switch path
- Reject kernel modules when instruction patching fails either due to
the DWARF-based SCS patching or because of an alternatives callback
residing outside of the core kernel text

smb: server: let smb_direct_disconnect_rdma_connection() turn CREATED into DISCONNECTED
When smb_direct_disconnect_rdma_connection() turns SMBDIRECT_SOCKET_CREATED
into SMBDIRECT_SOCKET_ERROR, we'll have the situation that
smb_direct_disconnect_rdma_work() will set SMBDIRECT_SOCKET_DISCONNECTING
and call rdma_disconnect(), which likely fails as we never reached
the RDMA_CM_EVENT_ESTABLISHED. it means that
wait_event(sc->status_wait, sc->status == SMBDIRECT_SOCKET_DISCONNECTED)
in free_transport() will hang forever in SMBDIRECT_SOCKET_DISCONNECTING
never reaching SMBDIRECT_SOCKET_DISCONNECTED.
So we directly go from SMBDIRECT_SOCKET_CREATED to
SMBDIRECT_SOCKET_DISCONNECTED.

Currently, CQs without a completion function are assigned the
mlx5_add_cq_to_tasklet function by default. This is problematic since
only user CQs created through the mlx5_ib driver are intended to use
this function.
Additionally, all CQs that will use doorbells instead of polling for
completions must call mlx5_cq_arm. However, the default CQ creation flow
leaves a valid value in the CQ's arm_db field, allowing FW to send
interrupts to polling-only CQs in certain corner cases.
These two factors would allow a polling-only kernel CQ to be triggered
by an EQ interrupt and call a completion function intended only for user
CQs, causing a null pointer exception.
Some areas in the driver have prevented this issue with one-off fixes
but did not address the root cause.
This patch fixes the described issue by adding defaults to the create CQ
flow. It adds a default dummy completion function to protect against
null pointer exceptions, and it sets an invalid command sequence number
by default in kernel CQs to prevent the FW from sending an interrupt to
the CQ until it is armed. User CQs are responsible for their own
initialization values.
Callers of mlx5_core_create_cq are responsible for changing the
completion function and arming the CQ per their needs.

net/mlx5e: Fix maxrate wraparound in threshold between units
The previous calculation used roundup() which caused an overflow for
rates between 25.5Gbps and 26Gbps.
For example, a rate of 25.6Gbps would result in using 100Mbps units with
value of 256, which would overflow the 8 bits field.
Simplify the upper_limit_mbps calculation by removing the
unnecessary roundup, and adjust the comparison to use <= to correctly
handle the boundary condition.

net: sched: initialize struct tc_ife to fix kernel-infoleak
This series addresses the uninitialization of the struct which has
2 bytes of padding. And copying this uninitialized data to userspace
can leak info from kernel memory.
This series ensures all members and padding are cleared prior to
begin copied.
This change silences the KMSAN report and prevents potential information
leaks from the kernel memory.
