Merge branch 'splice-net-switch-over-users-of-sendpage-and-remove-it'
David Howells says:
====================
splice, net: Switch over users of sendpage() and remove it
Here's the final set of patches towards the removal of sendpage. All the
drivers that use sendpage() get switched over to using sendmsg() with
MSG_SPLICE_PAGES.
The following changes are made:
(1) Make the protocol drivers behave according to MSG_MORE, not
MSG_SENDPAGE_NOTLAST. The latter is restricted to turning on MSG_MORE
in the sendpage() wrappers.
(2) Fix ocfs2 to allocate its global protocol buffers with folio_alloc()
rather than kzalloc() so as not to invoke the !sendpage_ok warning in
skb_splice_from_iter().
(3) Make ceph/rds, skb_send_sock, dlm, nvme, smc, ocfs2, drbd and iscsi
use sendmsg(), not sendpage and make them specify MSG_MORE instead of
MSG_SENDPAGE_NOTLAST.
(4) Kill off sendpage and clean up MSG_SENDPAGE_NOTLAST.

net: Kill MSG_SENDPAGE_NOTLAST
Now that ->sendpage() has been removed, MSG_SENDPAGE_NOTLAST can be cleaned
up. Things were converted to use MSG_MORE instead, but the protocol
sendpage stubs still convert MSG_SENDPAGE_NOTLAST to MSG_MORE, which is now
unnecessary.

ocfs2: Fix use of slab data with sendpage
ocfs2 uses kzalloc() to allocate buffers for o2net_hand, o2net_keep_req and
o2net_keep_resp and then passes these to sendpage. This isn't really
allowed as the lifetime of slab objects is not controlled by page ref -
though in this case it will probably work. sendmsg() with MSG_SPLICE_PAGES
will, however, print a warning and give an error.
Fix it to use folio_alloc() instead to allocate a buffer for the handshake
message, keepalive request and reply messages.

Merge branch 'net-stmmac-introduce-devres-helpers-for-stmmac-platform-drivers'
Bartosz Golaszewski says:
====================
net: stmmac: introduce devres helpers for stmmac platform drivers
The goal of this series is two-fold: to make the API for stmmac platforms more
logically correct (by providing functions that acquire resources with release
counterparts that undo only their actions and nothing more) and to provide
devres variants of commonly use registration functions that allows to
significantly simplify the platform drivers.
The current pattern for stmmac platform drivers is to call
stmmac_probe_config_dt(), possibly the platform's init() callback and then
call stmmac_drv_probe(). The resources allocated by these calls will then
be released by calling stmmac_pltfr_remove(). This goes against the commonly
accepted way of providing each function that allocated a resource with a
function that frees it.
First: provide wrappers around platform's init() and exit() callbacks that
allow users to skip checking if the callbacks exist manually.
Second: provide stmmac_pltfr_probe() which calls the platform init() callback
and then calls stmmac_drv_probe() together with a variant of
stmmac_pltfr_remove() that DOES NOT call stmmac_remove_config_dt(). For now
this variant is called stmmac_pltfr_remove_no_dt() but once all users of
the old stmmac_pltfr_remove() are converted to the devres helper, it will be
renamed back to stmmac_pltfr_remove() and the no_dt function removed.
Finally use the devres helpers in dwmac-qco-ethqos to show how much simplier
the driver's probe() becomes.
This series obviously just starts the conversion process and other platform
drivers will need to be converted once the helpers land in net/.

net/tcp: optimise locking for blocking splice
Even when tcp_splice_read() reads all it was asked for, for blocking
sockets it'll release and immediately regrab the socket lock, loop

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

Merge branch 'mlxsw-maintain-candidate-rifs'
Petr Machata says:
====================
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.

mlxsw: spectrum_router: Track next hops at CRIFs
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.

Extract from mlxsw_sp_nexthop_type_fini() a helper that covers the

mlxsw: spectrum_router: Link CRIFs to RIFs
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.

mlxsw: spectrum_router: Maintain a hash table of CRIFs
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.

mlxsw: spectrum_router: Use mlxsw_sp_ul_rif_get() to get main VRF LB RIF
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.

igb: Fix igb_down hung on surprise removal
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.

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.

net: dsa: microchip: simplify ksz_prmw8()
Implement ksz_prmw8() in terms of ksz_rmw8(), just as all the other
ksz_pX are implemented in terms of ksz_X. No functional change.

tools: ynl: improve the direct-include header guard logic
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.

net: txgbe: remove unused buffer in txgbe_calc_eeprom_checksum
Half a year passed since commit
049fe5365324c ("net: txgbe: Add operations
to interact with firmware") was submitted, the buffer in
txgbe_calc_eeprom_checksum was not used. So remove it and the related
branch codes.
