ice: Improve miscellaneous interrupt code
Jacob Keller says:
This series improves the driver's use of the threaded IRQ and the
communication between ice_misc_intr() and the ice_misc_intr_thread_fn()
which was previously introduced by commit
1229b33973c7 ("ice: Add low
latency Tx timestamp read").
First, a new custom enumerated return value is used instead of a boolean for
ice_ptp_process_ts(). This significantly reduces the cognitive burden when
reviewing the logic for this function, as the expected action is clear from
the return value name.
Second, the unconditional loop in ice_misc_intr_thread_fn() is removed,
replacing it with a write to the Other Interrupt Cause register. This causes
the MAC to trigger the Tx timestamp interrupt again. This makes it possible
to safely use the ice_misc_intr_thread_fn() to handle other tasks beyond
just the Tx timestamps. It is also easier to reason about since the thread
function will exit cleanly if we do something like disable the interrupt and
call synchronize_irq().
Third, refactor the handling for external timestamp events to use the
miscellaneous thread function. This resolves an issue with the external
time stamps getting blocked while processing the periodic work function
task.
Fourth, a simplification of the ice_misc_intr() function to always return
IRQ_WAKE_THREAD, and schedule the ice service task in the
ice_misc_intr_thread_fn() instead.
Finally, the Other Interrupt Cause is kept disabled over the thread function
processing, rather than immediately re-enabled.
Special thanks to Michal Schmidt for the careful review of the series and
pointing out my misunderstandings of the kernel IRQ code. It has been
determined that the race outlined as being fixed in previous series was
actually introduced by this series itself, which I've since corrected.

When offloading a TC encap action, the action information for the

available for the destination address, we can't construct the Ethernet
header to prepend to the packet. In this case, we still offload the
flow rule, but with its action-set-list ID pointing at a "fallback"
action which simply delivers the packet to its default destination (as
though no flow rule had matched), thus allowing software TC to handle
it. Later, when we receive a neighbouring update that allows us to
construct the encap header, the rule will become "ready" and we will
update its action-set-list ID in hardware to point at the actual
offloaded actions.

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: Add a splice_eof op to file-ops and socket-ops
Add an optional method, ->splice_eof(), to allow splice to indicate the
premature termination of a splice to struct file_operations and struct
proto_ops.
This is called if sendfile() or splice() encounters all of the following
conditions inside splice_direct_to_actor():
(1) the user did not set SPLICE_F_MORE (splice only), and
(2) an EOF condition occurred (->splice_read() returned 0), and
(3) we haven't read enough to fulfill the request (ie. len > 0 still), and
(4) we have already spliced at least one byte.
A further patch will modify the behaviour of SPLICE_F_MORE to always be
passed to the actor if either the user set it or we haven't yet read
sufficient data to fulfill the request.

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

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.

ice: do not re-enable miscellaneous interrupt until thread_fn completes
The ice driver uses threaded IRQ for managing Tx timestamps via the
devm_request_threaded_irq() interface. The ice_misc_intr() handler function
is responsible for processing the hard interrupt context, and can wake the
ice_misc_intr_thread_fn() by returning IRQ_WAKE_THREAD.
The request_threaded_irq() function comment says:
@handler is still called in hard interrupt context and has to check
whether the interrupt originates from the device. If yes, it needs to
disable the interrupt on the device and return IRQ_WAKE_THREAD which will
wake up the handler thread and run the @thread_fn.
We currently re-enable the Other Interrupt Cause Register (OCIR) at the end of
ice_misc_intr(). In practice, this seems to be ok, but it can make
communicating between the handler function and the thread function
difficult. This is because the interrupt can trigger again while the thread
function is still processing.
Move the OICR update to the end of the thread function, leaving the other
interrupt cause disabled in hardware until we complete one pass of the
thread function. This prevents the miscellaneous interrupt from firing
until after we finish the thread function.

ice: trigger PFINT_OICR_TSYN_TX interrupt instead of polling
In ice_misc_intr_thread_fn(), if we do not complete all Tx timestamp work,
the thread function will poll continuously forever.
For E822 hardware, this wastes time as the return value from
ice_ptp_process_ts() is accurate and always reports correctly that the PHY
actually has new timestamp data.
In addition, if we receive enough timestamps with the right pacing, we may
never exit this polling. Should this occur, other tasks handled by the
ice_misc_intr_thread_fn() will never be processed.
Fix this by instead writing to PFINT_OICR, causing an emulated interrupt to
be triggered immediately. This does take slightly more processing than just
re-checking the timestamps. However, it allows all of the other interrupt
causes a chance to be processed first in the hard IRQ function.
Note that the OICR interrupt is configured to be throttled to no more than
once every 124 microseconds. This gives an effective interrupt rate of
~8000 interrupts per second. This should thus not cause a significant
increase in overall CPU usage when compared to sleeping.

ice: introduce ICE_TX_TSTAMP_WORK enumeration
The ice_ptp_process_ts() function and its various helper functions return a
boolean value indicating whether any work is remaining. This use of a
boolean has grown confusing as we have multiple helpers that pass status
between each other. Readers must be aware of what "true" and "false" mean,
and it is very easy to get their meaning inverted. The names of the
functions are not standard "yes/no" questions, which is the best practice
for boolean returns.
Replace this use of an enumeration with a custom type, enum
ice_tx_tstamp_work. This enumeration clearly indicates whether all work is
done, or if more work is pending.
To aid in readability, factor the actual list iteration and processing out
into ice_ptp_process_tx_tstamp(), making it void. Then call this in
ice_ptp_tx_tstamp() ensuring that we always check the Tracker list at the
end when determining the appropriate return value.
Now the return value is an explicit name instead of the true or false
value. This is easier to follow and makes reading the resulting callers
much simpler.
In addition, this paves the way for future work to allow E822 hardware to
process timestamps for all functions using a single interrupt on the clock
owning PF.

ice: always return IRQ_WAKE_THREAD in ice_misc_intr()
Refactor the ice_misc_intr() function to always return IRQ_WAKE_THREAD, and
schedule the service task during the soft IRQ thread function instead of at
the end of the hard IRQ handler.
Remove the duplicate call to ice_service_task_schedule() that happened when
we got a PCI exception.
