This changes the re-arm of the timer from 10us to the user-defined

10us can be either too short or to large depending on the speed so we
let user configure it. The default value of the timer is 1ms but it can

xen-netback: switch state to InitWait at the end of netback_probe()...
...as the comment above the function states.
The switch to Initialising at the start of the function is somewhat bogus
as the toolstack will have set that initial state anyway. To behave
correctly, a backend should switch to InitWait once it has set up all
xenstore values that may be required by a initialising frontend. This
patch calls backend_switch_state() to make the transition at the
appropriate point.
NOTE: backend_switch_state() ignores errors from xenbus_switch_state()
and so this patch removes an error path from netback_probe(). This
means a failure to change state at this stage (in the absence of
other failures) will leave the device instantiated. This is highly
unlikley to happen as a failure to change state would indicate a
failure to write to xenstore, and that will trigger other error
paths. Also, a 'stuck' device can still be cleaned up using 'unbind'
in any case.

tipc: don't send gap blocks in ACK messages
In the commit referred to below we eliminated sending of the 'gap'
indicator in regular ACK messages, reserving this to explicit NACK
ditto.
Unfortunately we missed to also eliminate building of the 'gap block'
area in ACK messages. This area is meant to report gaps in the
received packet sequence following the initial gap, so that lost
packets can be retransmitted earlier and received out-of-sequence
packets can be released earlier. However, the interpretation of those
blocks is dependent on a complete and correct sequence of gaps and
acks. Hence, when the initial gap indicator is missing a single gap
block will be interpreted as an acknowledgment of all preceding
packets. This may lead to packets being released prematurely from the
sender's transmit queue, with easily predicatble consequences.
We now fix this by not building any gap block area if there is no
initial gap to report.

Russell King says:
====================
improve clause 45 support in phylink
These three patches improve the clause 45 support in phylink, fixing
some corner cases that have been noticed with the addition of SFP+
NBASE-T modules, but are actually a little more wisespread than I
initially realised.
The first issue was spotted with a NBASE-T PHY on a SFP+ module plugged
into a mvneta platform. When these PHYs are not operating in USXGMII
mode, but are in a single-lane Serdes mode, they will switch between
one of several different PHY interface modes.
If we call the MAC validate() function with the current PHY interface
mode, we will restrict the supported and advertising masks to the link
modes that the current PHY interface mode supports. For example, if we
determine that we want to start the PHY with an interface mode of
2500BASE-X, then this setup will restrict the advertisement and
supported masks to 2.5G speed link modes.
What we actually want for these PHYs is to allow them to support any
link modes that the PHY supports _and_ the MAC is also capable of
supporting. Without knowing the details of the PHY interface modes that
may be used, we can do this by using PHY_INTERFACE_MODE_NA to validate
and restrict the link modes to any that the MAC supports.
mvpp2 with the 88X3310 PHY avoids this problem, because the validate()
implementation allows all MAC supported speeds not only for
PHY_INTERFACE_MODE_NA, but also for XAUI and 10GKR modes.
The first patch addresses this; current MAC drivers should continue to
work as-is, but there will be a follow-on patch to fixup at least
mvpp2.
The second issue addresses a very similar problem that occurs when
trying to use ethtool to alter the advertisement mask - we call
the MAC validate() function with the current interface mode, the
current support and requested advertisement masks. This immediately
restricts the advertisement in the same way as the above.
This patch series addresses both issues, although the patches are not
in the above order.

modes.

net: phylink: extend clause 45 PHY validation workaround
Commit
e45d1f5288b8 ("net: phylink: support Clause 45 PHYs on SFP+
modules") added a workaround to support clause 45 PHYs which
dynamically switch their interface mode on SFP+ modules. This was
implemented by validating the PHYs supported/advertising using
PHY_INTERFACE_MODE_NA, rather than the specific interface mode that
we attached the PHY with.
However, we already have a situation where phylink is used to connect
a Marvell 88X3310 PHY which also behaves in exactly the same way, but
which seemingly doesn't need this. The reason seems to be that the
mvpp2 driver sets a whole bunch of link modes for
PHY_INTERFACE_MODE_10GKR down to 10Mb/s, despite 10GBASE-R not actually
supporting anything but 10Gb/s speeds.
When testing with drivers that (correctly) take the mvneta approach,
where the validate() method only returns what can be supported /
advertised for the specified link mode, we find that Clause 45 PHYs do
not behave as we expect: their advertisement is restricted to what
the current link will support, rather than what the PHY supports
through its dynamic switching.
Extend this workaround to all such cases; if we have a Clause 45 PHY
attaching via any means, except in USXGMII, XAUI and RXAUI which are
all unable to support this dynamic switching or have other solutions
to it, then we need to validate using PHY_INTERFACE_MODE_NA.
This should allow mvpp2 to switch to a more conformant validate()
implementation.

While testing ethtool with the Methode DM7052 module, it was noticed
that attempting to set the advertising mask results in the mask being
truncated to the support offered by the currently chosen PHY interface
mode.
When a PHY dynamically changes the PHY interface mode, limiting the
advertising mask in this way is not correct - if the PHY happened to
negotiate 10GBASE-T, and selected 10GBASE-R as the host interface, we
don't want to restrict the advertisement to just 10GBASE-* modes.
Rework setting the advertisement to take account of this; do not pass
the requested advertisement through phylink_validate(), but rely on
the advertisement restriction (supported mask) set when the PHY was

eventually and then into net.git, I'll get net.git building there too on

Ido Schimmel says:
====================
Simplify IPv4 route offload API
Motivation
==========
The aim of this patch set is to simplify the IPv4 route offload API by
making the stack a bit smarter about the notifications it is generating.
This allows driver authors to focus on programming the underlying device
instead of having to duplicate the IPv4 route insertion logic in their
driver, which is error-prone.
This is the first patch set out of a series of four. Subsequent patch
sets will simplify the IPv6 API, add offload/trap indication to routes
and add tests for all the code paths (including error paths). Available
here [1].
Details
=======
Today, whenever an IPv4 route is added or deleted a notification is sent
in the FIB notification chain and it is up to offload drivers to decide
if the route should be programmed to the hardware or not. This is not an
easy task as in hardware routes are keyed by {prefix, prefix length,
table id}, whereas the kernel can store multiple such routes that only
differ in metric / TOS / nexthop info.
This series makes sure that only routes that are actually used in the
data path are notified to offload drivers. This greatly simplifies the
work these drivers need to do, as they are now only concerned with
programming the hardware and do not need to replicate the IPv4 route
insertion logic and store multiple identical routes.
The route that is notified is the first FIB alias in the FIB node with
the given {prefix, prefix length, table ID}. In case the route is
deleted and there is another route with the same key, a replace
notification is emitted. Otherwise, a delete notification is emitted.
The above means that in the case of multiple routes with the same key,
but different TOS, only the route with the highest TOS is notified.
While the kernel can route a packet based on its TOS, this is not
supported by any hardware devices I am familiar with. Moreover, this is
not supported by IPv6 nor by BIRD/FRR from what I could see. Offload
drivers should therefore use the presence of a non-zero TOS as an
indication to trap packets matching the route and let the kernel route
them instead. mlxsw has been doing it for the past two years.
Testing
=======
To ensure there is no degradation in route insertion rates, I averaged
the insertion rate of 512k routes (/24 and /32) over 50 runs. Did not
observe any degradation.
Functional tests are available here [1]. They rely on route trap
indication, which is only added in the last patch set.
In addition, I have been running syzkaller for the past week with all
four patch sets and debug options enabled. Did not observe any problems.

Allow greater variance in a run and retry to further reduce flakiness.
Observed errors are one of two kinds: either the packet arrives too
early or late at recv(), or it was dropped in the qdisc itself and the
recv() call times out.
In the latter case, the qdisc queues a notification to the error
queue of the send socket. Also explicitly report this cause.

* A fix for an issue which might occur due to the XDP_TX patch. I see fit
to place it as a standalone patch for clarity.
Difference from v2:
* Fixed the usage of rx headroom (XDP_PACKET_HEADROOM)
* Aligned the page_offset of the packet when passing it to the stack
* Switched to using xdp_frame in xdp xmit queue
* Dropped the print for unsupported commands
* Cosmetic changes
Difference from RFC v1 (XDP_DROP patch):
* Initialized xdp.rxq pointer
* Updated max_mtu on attachment of xdp and removed the check from
ena_change_mtu()
* Moved the xdp execution from ena_rx_skb() to ena_clean_rx_irq()
* Moved xdp buff (struct xdp_buff) from rx_ring to the local stack
* Started using netlink's extack mechanism to deliver error messages to
the user

====================
ethtool netlink interface, preliminary part
As Jakub Kicinski suggested in ethtool netlink v7 discussion, this
submission consists only of preliminary patches which raised no objections;
first four patches already have Acked-by or Reviewed-by.
- patch 1 exposes permanent hardware address (as shown by "ethtool -P")
via rtnetlink
- patch 2 is renames existing netlink helper to a better name
- patch 3 and 4 reorganize existing ethtool code (no functional change)
- patch 5 makes the table of link mode names available as an ethtool string
set (will be needed for the netlink interface)
Once we get these out of the way, v8 of the first part of the ethtool
netlink interface will follow.
Changes from v2 to v3: fix SPDX licence identifiers (patch 3 and 5).
Changes from v1 to v2: restore build time check that all link modes have
assigned a name (patch 5).

ethtool: provide link mode names as a string set

To allow userspace to access all link modes running kernel supports, add

====================
vsock: add local transport support
v2:
- style fixes [Dave]
- removed RCU sync and changed 'the_vsock_loopback' in a global
static variable [Stefan]
- use G2H transport when local transport is not loaded and remote cid
is VMADDR_CID_LOCAL [Stefan]
- rebased on net-next
v1: https://patchwork.kernel.org/cover/
11251735/
This series introduces a new transport (vsock_loopback) to handle
local communication.
This could be useful to test vsock core itself and to allow developers
to test their applications without launching a VM.
Before this series, vmci and virtio transports allowed this behavior,
but only in the guest.
We are moving the loopback handling in a new transport, because it
might be useful to provide this feature also in the host or when
no H2G/G2H transports (hyperv, virtio, vmci) are loaded.
The user can use the loopback with the new VMADDR_CID_LOCAL (that
replaces VMADDR_CID_RESERVED) in any condition.
Otherwise, if the G2H transport is loaded, it can also use the guest
local CID as previously supported by vmci and virtio transports.
If G2H transport is not loaded, the user can also use VMADDR_CID_HOST
for local communication.
Patch 1 is a cleanup to build virtio_transport_common without virtio
Patch 2 adds the new VMADDR_CID_LOCAL, replacing VMADDR_CID_RESERVED
Patch 3 adds a new feature flag to register a loopback transport
Patch 4 adds the new vsock_loopback transport based on the loopback
implementation of virtio_transport

communication

2. drop EEPROM ID from sfp_select_interface()
3. add more compliance code definitions from SFF-8024, renaming the
existing definitions.
4. add module start/stop methods so phylink knows when a module is
about to become active. The module start method is called after
we have probed for a PHY on the module.
5. move start/stop of module PHY down into phylink using the new
module start/stop methods.
6. add support for Clause 45 I2C accesses, tested with Methode DM7052.
Other modules appear to use the same protocol, but slight
differences, but I do not have those modules to test with.
(if someone does, please holler!)
7. rearrange how we attach to PHYs so that we can support Clause 45
PHYs with indeterminant interface modes. (Clause 45 PHYs appear
to like to change their PHY interface mode depending on the
negotiated speed.)
8. add support for phylink to connect to a clause 45 PHY on a SFP
module.
9. split the link_an_mode between the configured value and the
currently selected mode value; some clause 45 PHYs have no
capability to provide in-band negotiation.
10. split the link configuration on SFP module insertion in phylink
so we can use it in other code paths.
11. delay MAC configuration for copper modules without a PHY to the
module start method - after any module PHY has been probed. If
the module has a PHY, then we setup the MAC when the PHY is
detected.
12. the Broadcom 84881 PHY does not support in-band negotiation even
though it uses SGMII and 2500BASE-X. Having the MAC operating
with in-band negotiation enabled, even with AN bypass enabled,
results in no link - Broadcom say that the host MAC must always
be forced.
13. add support for the Broadcom 84881 PHY found on the Methode
DM7052 module.

modules.
