Add a method to query the PHY's in-band capabilities for a PHY
interface mode.
Where the interface mode does not have in-band capability, or the PHY
driver has not been updated to return this information, then
phy_inband_caps() should return zero. Otherwise, PHY drivers will
return a value consisting of the following flags:
LINK_INBAND_DISABLE indicates that the hardware does not support
in-band signalling, or can have in-band signalling configured via
software to be disabled.
LINK_INBAND_ENABLE indicates that the hardware will use in-band
signalling, or can have in-band signalling configured via software
to be enabled.
LINK_INBAND_BYPASS indicates that the hardware has the ability to
bypass in-band signalling when enabled after a timeout if the link
partner does not respond to its in-band signalling.
This reports the PHY capabilities for the particular interface mode,
not the current configuration.

There is an interdependence between the current link_an_mode and
pcs_neg_mode that some drivers rely upon to know whether inband or PHY
mode will be used.
In order to support detection of PCS and PHY inband capabilities
resulting in automatic selection of inband or PHY mode, we need to
cater for this, and support changing the MAC link_an_mode. However, we
end up with an inter-dependency between the current link_an_mode and
pcs_neg_mode.
To solve this, split the current link_an_mode into the requested
link_an_mode and active link_an_mode. The requested link_an_mode will
always be passed to phylink_pcs_neg_mode(), and the active link_an_mode
will be used for everything else, and only updated during
phylink_major_config(). This will ensure that phylink_pcs_neg_mode()'s
link_an_mode will not depend on the active link_an_mode that will,
in a future patch, depend on pcs_neg_mode.

Move the call to phylink_pcs_neg_mode() in phylink_major_config() after
we have selected the appropriate PCS to allow the PCS to be passed in.
Add struct phylink and struct phylink_pcs pointers to
phylink_pcs_neg_mode() and pass in the appropriate structures. Set
pl->pcs_neg_mode before returning, and remove the return value.
This will allow the capabilities of the PCS and any PHY to be used when
deciding which pcs_neg_mode should be used.

netcons: Add udp send fail statistics to netconsole
Enhance observability of netconsole. Packet sends can fail.
Start tracking at least two failure possibilities: ENOMEM and
NET_XMIT_DROP for every target. Stats are exposed via an additional
attribute in CONFIGFS.
The exposed statistics allows easier debugging of cases when netconsole
messages were not seen by receivers, eliminating the guesswork if the
sender thinks that messages in question were sent out.
Stats are not reset on enable/disable/change remote ip/etc, they
belong to the netcons target itself.

netpoll_send_udp can return if send was successful.
It will allow client code to be aware of the send status.
Possible return values are the result of __netpoll_send_skb (cast to int)

instantaneously and was scheduled for later, __netpoll__send_skb returns
success in that case.

In the __netpoll_setup() function, when accessing the device's npinfo
pointer, replace rcu_access_pointer() with rtnl_dereference(). This
change is more appropriate, as suggested by Herbert Xu[1].
The function is called with the RTNL mutex held, and the pointer is
being dereferenced later, so, dereference earlier and just reuse the
pointer for the if/else.
The replacement ensures correct pointer access while maintaining
the existing locking and RCU semantics of the netpoll subsystem.

After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all platform drivers below drivers/ptp to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.
While touching these drivers, make the alignment of the touched
initializers consistent.

Several places call ip6mr_get_table() with no RCU nor RTNL lock.
Add RCU protection inside such helper and provide a lockless variant
for the few callers that already acquired the relevant lock.
Note that some users additionally reference the table outside the RCU
lock. That is actually safe as the table deletion can happen only
after all table accesses are completed.

The multicast route tables lifecycle, for both ipv4 and ipv6, is
protected by RCU using the RTNL lock for write access. In many
places a table pointer escapes the RCU (or RTNL) protected critical
section, but such scenarios are actually safe because tables are
deleted only at namespace cleanup time or just after allocation, in
case of default rule creation failure.
Tables freed at namespace cleanup time are assured to be alive for the
whole netns lifetime; tables freed just after creation time are never
exposed to other possible users.
Ensure that the free conditions are respected in ip{,6}mr_free_table, to
document the locking schema and to prevent future possible introduction
of 'table del' operation from breaking it.

Recent kernels cause a lot of TCP retransmissions
[ ID] Interval Transfer Bitrate Retr Cwnd
[ 5] 0.00-1.00 sec 2.24 GBytes 19.2 Gbits/sec 2767 442 KBytes
[ 5] 1.00-2.00 sec 2.23 GBytes 19.1 Gbits/sec 2312 350 KBytes
^^^^
Replacing the qdisc with pfifo makes retransmissions go away.
It appears that a flow may have a delayed packet with a very near
Tx time. Later, we may get busy processing Rx and the target Tx time
will pass, but we won't service Tx since the CPU is busy with Rx.
If Rx sees an ACK and we try to push more data for the delayed flow
we may fastpath the skb, not realizing that there are already "ready
to send" packets for this flow sitting in the qdisc.
Don't trust the fastpath if we are "behind" according to the projected
Tx time for next flow waiting in the Qdisc. Because we consider anything
within the offload window to be okay for fastpath we must consider
the entire offload window as "now".
Qdisc config:
qdisc fq 8001: dev eth0 parent 1234:1 limit 10000p flow_limit 100p \
buckets 32768 orphan_mask 1023 bands 3 \
priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1 \

low_rate_threshold 550Kbit \
refill_delay 40ms timer_slack 10us horizon 10s horizon_drop
For iperf this change seems to do fine, the reordering is gone.
The fastpath still gets used most of the time:
gc 0 highprio 0 fastpath 142614 throttled 418309 latency 19.1us
xx_behind 2731
where "xx_behind" counts how many times we hit the new "return false".

The cited commit replaced inet_csk_reqsk_queue_drop_and_put() with
__inet_csk_reqsk_queue_drop() and reqsk_put() in reqsk_timer_handler().
Then, oreq should be passed to reqsk_put() instead of req; otherwise
use-after-free of nreq could happen when reqsk is migrated but the
retry attempt failed (e.g. due to timeout).
Let's pass oreq to reqsk_put().

When phy_ethtool_set_eee_noneg() detects a change in the LPI
parameters, it attempts to update phylib state and trigger the link
to cycle so the MAC sees the updated parameters.
However, in doing so, it sets phydev->enable_tx_lpi depending on
whether the EEE configuration allows the MAC to generate LPI without
taking into account the result of negotiation.
This can be demonstrated with a 1000base-T FD interface by:
# ethtool --set-eee eno0 advertise 8 # cause EEE to be not negotiated
# ethtool --set-eee eno0 tx-lpi off
# ethtool --set-eee eno0 tx-lpi on
This results in being true, despite EEE not having been negotiated and:
# ethtool --show-eee eno0
EEE status: enabled - inactive
Tx LPI: 250 (us)
Supported EEE link modes: 100baseT/Full
1000baseT/Full
Advertised EEE link modes: 100baseT/Full
1000baseT/Full
Fix this by keeping track of whether EEE was negotiated via a new
eee_active member in struct phy_device, and include this state in
the decision whether phydev->enable_tx_lpi should be set.

net: Fix some callers of copy_from_sockptr()
Some callers misinterpret copy_from_sockptr()'s return value. The function
follows copy_from_user(), i.e. returns 0 for success, or the number of
bytes not copied on error. Simply returning the result in a non-zero case
isn't usually what was intended.
Compile tested with CONFIG_LLC, CONFIG_AF_RXRPC, CONFIG_BT enabled.
Last patch probably belongs more to net-next, if any. Here as an RFC.

copy_from_sockptr() does not return negative value on error; instead, it
reports the number of bytes that failed to copy. Since it's deprecated,
switch to copy_safe_from_sockptr().
Note: Keeping the `optlen != sizeof(unsigned int)` check as
copy_safe_from_sockptr() by itself would also accept
optlen > sizeof(unsigned int). Which would allow a more lenient handling
of inputs.

"Apart from the gpio-exar fix which addresses an older issue, they all
fix regressions from this release cycle:
- fix missing GPIO chip labels in gpio-zevio and gpio-altera
- for the latter: also set GPIO base to -1 to use dynamic range
allocation
- fix value setting with external pull-up/down resistor in gpio-exar
- use the recommended IDA interfaces in gpio-mpsse"
* tag 'gpio-fixes-for-v6.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux:
gpio: mpsse: Remove usage of the deprecated ida_simple_xx() API
gpio: exar: set value when external pull-up or pull-down is present
gpio: altera: Add missed base and label initialisations
gpio: zevio: Add missed label initialisation
A small number of improvements all over the place.

- Constify an unmodified structure used in linking vfio and kvm.
(Christophe JAILLET)
- Add ID for an additional hardware SKU supported by the nvgrace-gpu
vfio-pci variant driver. (Ankit Agrawal)
- Fix incorrect signed cast in QAT vfio-pci variant driver, negating
test in check_add_overflow(), though still caught by later tests.
(Giovanni Cabiddu)
- Additional debugfs attributes exposed in hisi_acc vfio-pci variant
driver for migration debugging. (Longfang Liu)
- Migration support is added to the virtio vfio-pci variant driver,
becoming the primary feature of the driver while retaining emulation
of virtio legacy support as a secondary option. (Yishai Hadas)
