David Howells says:
====================
splice, net: Rewrite splice-to-socket, fix SPLICE_F_MORE and handle MSG_SPLICE_PAGES in AF_TLS
Here are patches to do the following:
(1) Block MSG_SENDPAGE_* flags from leaking into ->sendmsg() from
userspace, whilst allowing splice_to_socket() to pass them in.
(2) Allow MSG_SPLICE_PAGES to be passed into tls_*_sendmsg(). Until
support is added, it will be ignored and a splice-driven sendmsg()
will be treated like a normal sendmsg(). TCP, UDP, AF_UNIX and
Chelsio-TLS already handle the flag in net-next.
(3) Replace a chain of functions to splice-to-sendpage with a single
function to splice via sendmsg() with MSG_SPLICE_PAGES. This allows a
bunch of pages to be spliced from a pipe in a single call using a
bio_vec[] and pushes the main processing loop down into the bowels of
the protocol driver rather than repeatedly calling in with a page at a
time.
(4) Provide a ->splice_eof() op[2] that allows splice to signal to its
output that the input observed a premature EOF and that the caller
didn't flag SPLICE_F_MORE, thereby allowing a corked socket to be
flushed. This attempts to maintain the current behaviour. It is also
not called if we didn't manage to read any data and so didn't called
the actor function.
This needs routing though several layers to get it down to the network
protocol.
[!] Note that I chose not to pass in any flags - I'm not sure it's
particularly useful to pass in the splice flags; I also elected
not to return any error code - though we might actually want to do
that.
(5) Provide tls_{device,sw}_splice_eof() to flush a pending TLS record if
there is one.
(6) Provide splice_eof() for UDP, TCP, Chelsio-TLS and AF_KCM. AF_UNIX
doesn't seem to pay attention to the MSG_MORE or MSG_SENDPAGE_NOTLAST
flags.
(7) Alter the behaviour of sendfile() and fix SPLICE_F_MORE/MSG_MORE
signalling[1] such SPLICE_F_MORE is always signalled until we have
read sufficient data to finish the request. If we get a zero-length
before we've managed to splice sufficient data, we now leave the
socket expecting more data and leave it to userspace to deal with it.
(8) Make AF_TLS handle the MSG_SPLICE_PAGES internal sendmsg flag.
MSG_SPLICE_PAGES is an internal hint that tells the protocol that it
should splice the pages supplied if it can. Its sendpage
implementations are then turned into wrappers around that.

splice, net: Fix SPLICE_F_MORE signalling in splice_direct_to_actor()
splice_direct_to_actor() doesn't manage SPLICE_F_MORE correctly[1] - and,
as a result, it incorrectly signals/fails to signal MSG_MORE when splicing
to a socket. The problem I'm seeing happens when a short splice occurs
because we got a short read due to hitting the EOF on a file: as the length
read (read_len) is less than the remaining size to be spliced (len),
SPLICE_F_MORE (and thus MSG_MORE) is set.
The issue is that, for the moment, we have no way to know *why* the short
read occurred and so can't make a good decision on whether we *should* keep
MSG_MORE set.
MSG_SENDPAGE_NOTLAST was added to work around this, but that is also set
incorrectly under some circumstances - for example if a short read fills a
single pipe_buffer, but the next read would return more (seqfile can do
this).
This was observed with the multi_chunk_sendfile tests in the tls kselftest
program. Some of those tests would hang and time out when the last chunk
of file was less than the sendfile request size:
build/kselftest/net/tls -r tls.12_aes_gcm.multi_chunk_sendfile
This has been observed before[2] and worked around in AF_TLS[3].
Fix this by making splice_direct_to_actor() always signal SPLICE_F_MORE if
we haven't yet hit the requested operation size. SPLICE_F_MORE remains
signalled if the user passed it in to splice() but otherwise gets cleared
when we've read sufficient data to fulfill the request.
If, however, we get a premature EOF from ->splice_read(), have sent at
least one byte and SPLICE_F_MORE was not set by the caller, ->splice_eof()
will be invoked.

splice, net: Use sendmsg(MSG_SPLICE_PAGES) rather than ->sendpage()
Replace generic_splice_sendpage() + splice_from_pipe + pipe_to_sendpage()
with a net-specific handler, splice_to_socket(), that calls sendmsg() with
MSG_SPLICE_PAGES set instead of calling ->sendpage().
MSG_MORE is used to indicate if the sendmsg() is expected to be followed
with more data.
This allows multiple pipe-buffer pages to be passed in a single call in a
BVEC iterator, allowing the processing to be pushed down to a loop in the
protocol driver. This helps pave the way for passing multipage folios down
too.
Protocols that haven't been converted to handle MSG_SPLICE_PAGES yet should
just ignore it and do a normal sendmsg() for now - although that may be a
bit slower as it may copy everything.

net: Block MSG_SENDPAGE_* from being passed to sendmsg() by userspace
It is necessary to allow MSG_SENDPAGE_* to be passed into ->sendmsg() to
allow sendmsg(MSG_SPLICE_PAGES) to replace ->sendpage(). Unblocking them
in the network protocol, however, allows these flags to be passed in by
userspace too[1].
Fix this by marking MSG_SENDPAGE_NOPOLICY, MSG_SENDPAGE_NOTLAST and
MSG_SENDPAGE_DECRYPTED as internal flags, which causes sendmsg() to object
if they are passed to sendmsg() by userspace. Network protocol ->sendmsg()
implementations can then allow them through.
Note that it should be possible to remove MSG_SENDPAGE_NOTLAST once
sendpage is removed as a whole slew of pages will be passed in in one go by
splice through sendmsg, with MSG_MORE being set if it has more data waiting
in the pipe.

1) Support 4 ports VF LAG, part 2/2
2) Few extra trivial cleanup patches
Shay Drory Says:
================
Support 4 ports VF LAG, part 2/2
This series continues the series[1] "Support 4 ports VF LAG, part1/2".
This series adds support for 4 ports VF LAG (single FDB E-Switch).
This series of patches refactoring LAG code that make assumptions
about VF LAG supporting only two ports and then enable 4 ports VF LAG.
Patch 1:
- Fix for ib rep code
Patches 2-5:
- Refactors LAG layer.
Patches 6-7:
- Block LAG types which doesn't support 4 ports.
Patch 8:
- Enable 4 ports VF LAG.
This series specifically allows HCAs with 4 ports to create a VF LAG
with only 4 ports. It is not possible to create a VF LAG with 2 or 3
ports using HCAs that have 4 ports.
Currently, the Merged E-Switch feature only supports HCAs with 2 ports.
However, upcoming patches will introduce support for HCAs with 4 ports.
In order to activate VF LAG a user can execute:
devlink dev eswitch set pci/0000:08:00.0 mode switchdev
devlink dev eswitch set pci/0000:08:00.1 mode switchdev
devlink dev eswitch set pci/0000:08:00.2 mode switchdev
devlink dev eswitch set pci/0000:08:00.3 mode switchdev
ip link add name bond0 type bond
ip link set dev bond0 type bond mode 802.3ad
ip link set dev eth2 master bond0
ip link set dev eth3 master bond0
ip link set dev eth4 master bond0
ip link set dev eth5 master bond0
Where eth2, eth3, eth4 and eth5 are net-interfaces of pci/0000:08:00.0
pci/0000:08:00.1 pci/0000:08:00.2 pci/0000:08:00.3 respectively.
User can verify LAG state and type via debugfs:

Russell King says:
====================
complete Lynx mdio device handling
This series completes the mdio device lifetime handling for Lynx PCS
users which do not create their own mdio device, but instead fetch
it using a firmware description - namely the DPAA2 and FMAN_MEMAC
drivers.
In a previous patch set, lynx_pcs_create() was modified to increase
the mdio device refcount, and lynx_pcs_destroy() to drop that
refcount.
The first two patches change these two drivers to put the reference
which they hold immediately after lynx_pcs_create(), effectively
handing the responsibility for maintaining the refcount to the Lynx
PCS driver.
A side effect of the first two patches is that lynx_get_mdio_device()
is no longer used, so patch 3 removes it.
Patch 4 adds a new helper - lynx_pcs_create_fwnode(), which creates
a Lynx PCS instance from the fwnode.
Patch 5 and 6 convert the two drivers to make use of this new helper,
which simply has to find the mdio device, and then create the Lynx
PCS from that.
With those conversions done, lynx_pcs_create() is no longer required
outside pcs-lynx.c, so remove it from public view.
Patch 8 we changes lynx_pcs_create() to return an error-pointer rather
than NULL to bring consistency to the return style, and means that we
can remove the NULL-to-error-pointer conversion from both
lynx_pcs_create_fwnode() and lynx_pcs_create_mdiodev().
Patch 9 adds a check for the fwnode being available, and returns an
-ENODEV error pointer if unavailable.
Patch 10 removes this check from DPAA2, detecting the error pointer
value to continue printing the helpful message.
Patch 11 removes this check from fman_memac, and in doing so fixes a
bug where if the node is unavailable, the reference count is not
dropped.

Admittedly the devlink.yaml spec is fairly limitted,

That's sufficient to be useful (monitoring FW versions

Merge branch 'crypto-splice-net-make-af_alg-handle-sendmsg-msg_splice_pages'
David Howells says:
====================
crypto, splice, net: Make AF_ALG handle sendmsg(MSG_SPLICE_PAGES)
Here are patches to make AF_ALG handle the MSG_SPLICE_PAGES internal
sendmsg flag. MSG_SPLICE_PAGES is an internal hint that tells the protocol
that it should splice the pages supplied if it can. The sendpage functions
are then turned into wrappers around that.
This set consists of the following parts:
(1) Move netfs_extract_iter_to_sg() to somewhere more general and rename
it to drop the "netfs" prefix. We use this to extract directly from
an iterator into a scatterlist.
(2) Make AF_ALG use iov_iter_extract_pages(). This has the additional
effect of pinning pages obtained from userspace rather than taking
refs on them. Pages from kernel-backed iterators would not be pinned,
but AF_ALG isn't really meant for use by kernel services.
(3) Change AF_ALG still further to use extract_iter_to_sg().
(4) Make af_alg_sendmsg() support MSG_SPLICE_PAGES support and make
af_alg_sendpage() just a wrapper around sendmsg(). This has to take
refs on the pages pinned for the moment.
(5) Make hash_sendmsg() support MSG_SPLICE_PAGES by simply ignoring it.
hash_sendpage() is left untouched to be removed later, after the
splice core has been changed to call sendmsg().

bnxt_en: Implement .set_port / .unset_port UDP tunnel callbacks
As per the new udp tunnel framework, drivers which need to know the
details of a port entry (i.e. port type) when it gets deleted should
use the .set_port / .unset_port callbacks.
Implementing the current .udp_tunnel_sync callback would mean that the
deleted tunnel port entry would be all zeros. This used to work on
older firmware because it would not check the input when deleting a
tunnel port. With newer firmware, the delete will now fail and
subsequent tunnel port allocation will fail as a result.
