Even when tcp_splice_read() reads all it was asked for, for blocking
sockets it'll release and immediately regrab the socket lock, loop
around and break on the while check.
Check tss.len right after we adjust it, and return if we're done.
That saves us one release_sock(); lock_sock(); pair per successful

mlxsw: Maintain candidate RIFs
The mlxsw driver currently makes the assumption that the user applies
configuration in a bottom-up manner. Thus netdevices need to be added to
the bridge before IP addresses are configured on that bridge or SVI added
on top of it. Enslaving a netdevice to another netdevice that already has
uppers is in fact forbidden by mlxsw for this reason. Despite this safety,
it is rather easy to get into situations where the offloaded configuration
is just plain wrong.
As an example, take a front panel port, configure an IP address: it gets a
RIF. Now enslave the port to the bridge, and the RIF is gone. Remove the
port from the bridge again, but the RIF never comes back. There is a number
of similar situations, where changing the configuration there and back
utterly breaks the offload.
The situation is going to be made better by implementing a range of replays
and post-hoc offloads.
This patch set lays the ground for replay of next hops. The particular
issue that it deals with is that currently, driver-specific bookkeeping for
next hops is hooked off RIF objects, which come and go across the lifetime
of a netdevice. We would rather keep these objects at an entity that
mirrors the lifetime of the netdevice itself. That way they are at hand and
can be offloaded when a RIF is eventually created.
To that end, with this patchset, mlxsw keeps a hash table of CRIFs:
candidate RIFs, persistent handles for netdevices that mlxsw deems
potentially interesting. The lifetime of a CRIF matches that of the
underlying netdevice, and thus a RIF can always assume a CRIF exists. A
CRIF is where next hops are kept, and when RIF is created, these next hops
can be easily offloaded. (Previously only the next hops created after the
RIF was created were offloaded.)
- Patches #1 and #2 are minor adjustments.
- In patches #3 and #4, add CRIF bookkeeping.
- In patch #5, link CRIFs to RIFs such that given a netdevice-backed RIF,
the corresponding CRIF is easy to look up.
- Patch #6 is a clean-up allowed by the previous patches
- Patches #7 and #8 move next hop tracking to CRIFs
No observable effects are intended as of yet. This will be useful once
there is support for RIF creation for netdevices that become mlxsw uppers,
which will come in following patch sets.

Move the list of next hops from struct mlxsw_sp_rif to mlxsw_sp_crif. The
reason is that eventually, next hops for mlxsw uppers should be offloaded
and unoffloaded on demand as a netdevice becomes an upper, or stops being
one. Currently, next hops are tracked at RIFs, but RIFs do not exist when a
netdevice is not an mlxsw uppers. CRIFs are kept track of throughout the
netdevice lifetime.
Correspondingly, track at each next hop not its RIF, but its CRIF (from
which a RIF can always be deduced).
Note that now that next hops are tracked at a CRIF, it is not necessary to
move each over to a new RIF when it is necessary to edit a RIF. Therefore
drop mlxsw_sp_nexthop_rif_migrate() and have mlxsw_sp_rif_migrate_destroy()
call mlxsw_sp_nexthop_rif_update() directly.

Nexthop finalization consists of two steps: the part where the offload is
removed, because the backing RIF is now gone; and the part where the
association to the RIF is severed.
Extract from mlxsw_sp_nexthop_type_fini() a helper that covers the
unoffloading part, mlxsw_sp_nexthop_type_rif_gone(), so that it can later
be called independently.
Note that this swaps around the ordering of mlxsw_sp_nexthop_ipip_fini()
vs. mlxsw_sp_nexthop_rif_fini(). The current ordering is more of a
historical happenstance than a conscious decision. The two cleanups do not
depend on each other, and this change should have no observable effects.

When a RIF is about to be created, the registration of the netdevice that
it should be associated with must have been seen in the past, and a CRIF
created. Therefore make this a hard requirement by looking up the CRIF
during RIF creation, and complaining loudly when there isn't one.
This then allows to keep a link between a RIF and its corresponding
CRIF (and back, as the relationship is one-to-at-most-one), which do.
The CRIF will later be useful as the objects tracked there will be
offloaded lazily as a result of RIF creation.
CRIFs are created when an "interesting" netdevice is registered, and
destroyed after such device is unregistered. CRIFs are supposed to already
exist when a RIF creation request arises, and exist at least as long as
that RIF exists. This makes for a simple invariant: it is always safe to
dereference CRIF pointer from "its" RIF.
To guarantee this, CRIFs cannot be removed immediately when the UNREGISTER
event is delivered. The reason is that if a RIF's netdevices has an IPv6
address, removal of this address is notified in an atomic block. To remove
the RIF, the IPv6 removal handler schedules a work item. It must be safe
for this work item to access the associated CRIF as well.
Thus when a netdevice that backs the CRIF is removed, if it still has a
RIF, do not actually free the CRIF, only toggle its can_destroy flag, which
this patch adds. Later on, mlxsw_sp_rif_destroy() collects the CRIF.

CRIFs are objects that mlxsw maintains for netdevices that may not have an
associated RIF (i.e. they may not have been instantiated in the ASIC), but
if indeed they do not, it is quite possible they will in the future. These
netdevices are candidate RIFs, hence CRIFs. Netdevices for which CRIFs are
created include e.g. bridges, LAGs, or front panel ports. The idea is that
next hops would be kept at CRIFs, not RIFs, and thus it would be easier to
offload and unoffload the entities that have been added before the RIF was
created.
In this patch, add the code for low-level CRIF maintenance: create and
destroy, and keep in a table keyed by the netdevice pointer for easy
recall.

The current function, mlxsw_sp_router_ul_rif_get(), is a wrapper around the
function mentioned in the subject. As such it forms an external interface
of the router code.
In future patches we will want to maintain connection between RIFs and the
CRIFs (introduced in the next patch) that back them. That will not hold
for the VRF-based loopback netdevices, so the whole CRIF business can be
kept hidden from the rest of mlxsw.
But for the main VRF loopback RIF we do want to keep the RIF-CRIF
connection, because that RIF is used for blackhole next hops, and the next
hop code can be kept simpler for assuming rif->crif is valid.
Hence, instead, call mlxsw_sp_ul_rif_get() to create the main VRF loopback
RIF. This being an internal function will take the CRIF argument anyway.
Furthermore, the function does not lock, which is not necessary at this
point in code yet.

Commit ad72c4a06a introduced optimization to return from function
quickly if the MAC address is not changing at all. It was reported
that such change causes dev->addr_assign_type to not change
to NET_ADDR_SET from _PERM or _RANDOM.
Restore the old behavior and skip only call to ndo_set_mac_address.

In a setup where a Thunderbolt hub connects to Ethernet and a display
through USB Type-C, users may experience a hung task timeout when they
remove the cable between the PC and the Thunderbolt hub.
This is because the igb_down function is called multiple times when
the Thunderbolt hub is unplugged. For example, the igb_io_error_detected
triggers the first call, and the igb_remove triggers the second call.
The second call to igb_down will block at napi_synchronize.
Here's the call trace:

In this case, igb_io_error_detected detaches the network interface
and requests a PCIE slot reset, however, the PCIE reset callback is
not being invoked and thus the Ethernet connection breaks down.
As the PCIE error in this case is a non-fatal one, requesting a
slot reset can be avoided.
This patch fixes the task hung issue and preserves Ethernet
connection by ignoring non-fatal PCIE errors.

net: dsa: microchip: fix writes to phy registers >= 0x10
Patch 1 is just a simplification, technically unrelated to the other
two patches. But it would be a bit inconsistent to have the new
ksz_prmw32() introduced in patch 2 use ksz_rmw32() while leaving
ksz_prmw8() as-is.
The actual fix is of course patch 3. I can definitely see some weird
behaviour on our ksz9567 when writing to phy registers 0x1e and 0x1f
(with phytool from userspace), though it does not seem that the effect
is always to write zeroes to the buddy register as the errata sheet
says would be the case. In our case, the switch is connected via i2c;
I hope somebody with other switches and/or the SPI variants can test
this.

According to the errata sheets for ksz9477 and ksz9567, writes to the
PHY registers 0x10-0x1f (i.e. those located at addresses 0xN120 to
0xN13f) must be done as a 32 bit write to the 4-byte aligned address
containing the register, hence requires a RMW in order not to change
the adjacent PHY register.

Przemek suggests that I shouldn't accuse GCC of witchcraft,
there is a simpler explanation for why we need manual define.
scripts/headers_install.sh modifies the guard, removing _UAPI.
That's why including a kernel header from the tree and from
/usr leads to duplicate definitions.
This also solves the mystery of why I needed to include
the header conditionally. I had the wrong guards for most
cases but ethtool.

====================
Add and use helper for PCS negotiation modes
Earlier this month, I proposed a helper for deciding whether a PCS
should use inband negotiation modes or not. There was some discussion
around this topic, and I believe there was no disagreement about
providing the helper.
The initial discussion can be found at:
https://lore.kernel.org/r/ZGIkGmyL8yL1q1zp@shell.armlinux.org.uk
Subsequently, I posted a RFC series back in May:
https://lore.kernel.org/r/ZGzhvePzPjJ0v2En@shell.armlinux.org.uk
that added a helper, phylink_pcs_neg_mode() which PCS drivers could use
to parse the state, and updated a bunch of drivers to use it. I got
a couple of bits of feedback to it, including some ACKs.
However, I've decided to take this slightly further and change the
"mode" parameter to both the pcs_config() and pcs_link_up() methods
when a PCS driver opts in to this (by setting "neg_mode" in the
phylink_pcs structure.) If this is not set, we default to the old
behaviour. That said, this series converts all the PCS implementations
I can find currently in net-next.
Doing this has the added benefit that the negotiation mode parameter
is also available to the pcs_link_up() function, which can now know
whether inband negotiation was in fact enabled or not at pcs_config()
time.
It has been posted as RFC at:
https://lore.kernel.org/r/ZIh/CLQ3z89g0Ua0@shell.armlinux.org.uk
and received one reply, thanks Elad, which is a similar amount of
interest to previous postings. Let's post it as non-RFC and see
whether we get more reaction.
