net: ipa: a mix of patches
This series includes a mix of things things that are generally
minor. The first four are sort of unrelated fixes, and summarizing
them here wouldn't be that helpful.
The last three together make it so only the "configuration data" we
need after initialization is saved for later use. Most such data is
used only during driver initialization. But endpoint configuration
is needed later, so the last patch saves a copy of that. Eventually
we'll want to support reconfiguring endpoints at runtime as well,
and this will facilitate that.
====================

All elements of the default endpoint configuration are used in the
code when programming an endpoint for use. But none of the other
configuration data is ever needed once things are initialized.
So rather than saving a pointer to *all* of the configuration data,
save a copy of only the endpoint configuration portion.
This will eventually allow endpoint configuration to be modifiable
at runtime. But even before that it means we won't keep a pointer
to configuration data after when no longer needed.

Rename the just-moved data structure types to drop the "_data"
suffix, to make it more obvious they are no longer meant to be used
just as read-only initialization data. Rename the fields and

If we program an RX endpoint to have no header (header length is 0),
header-related endpoint configuration values are meaningless and are
ignored.
The only case we support that defines a header is QMAP endpoints.
In ipa_endpoint_init_hdr_ext() we set the endianness mask value
unconditionally, but it should not be done if there is no header
(meaning it is not configured for QMAP).
Set the endianness conditionally, and rearrange the logic in that
function slightly to avoid testing the qmap flag twice.

The MPTCP socket's conn_list (list of subflows) requires the socket lock
to access. The MP_FAIL timeout code added such an access, where it would
check the list of subflows both in timer context and (later) in workqueue
context where the socket lock is held.
Rather than check the list twice, remove the check in the timeout
handler and only depend on the check in the workqueue. Also remove the
MPTCP_FAIL_NO_RESPONSE flag, since mptcp_mp_fail_no_response() has
insignificant overhead and can be checked on each worker run.

MP_FAIL timeout (waiting for a peer to respond to an MP_FAIL with
another MP_FAIL) is implemented using the MPTCP socket's sk_timer. That
timer is also used at MPTCP socket close, so it's important to not have
the two timer users interfere with each other.
At MPTCP socket close, all subflows are orphaned before sk_timer is
manipulated. By checking the SOCK_DEAD flag on the subflows, each
subflow can determine if the timer is safe to alter without acquiring
any MPTCP-level lock. This replaces code that was using the
mptcp_data_lock and MPTCP-level socket state checks that did not
correctly protect the timer.

The mentioned helper requires the msk socket lock, and the
current callers don't own it nor can't acquire it, so the
access is racy.
All the current callers are really checking for infinite mapping
fallback, and the latter condition is explicitly tracked by
the relevant msk variable: we can safely remove the caller usage
- and the caller itself.
The issue is present since MP_FAIL implementation, but the
fix only applies since the infinite fallback support, ence the

This patch improves TCP PRR loss recovery behavior for a corner
case. Previously during PRR conservation-bound mode, it strictly
sends the amount equals to the amount newly acked or s/acked.
The patch changes s.t. PRR may send additional amount that was banked
previously (e.g. application-limited) in the conservation-bound
mode, similar to the slow-start mode. This unifies and simplifies the
algorithm further and may improve the recovery latency. This change
still follow the general packet conservation design principle and
always keep inflight/cwnd below the slow start threshold set
by the congestion control module.

mtk_eth_soc phylink updates
This series ultimately updates mtk_eth_soc to use phylink_pcs, with some
fixes along the way.
Previous attempts to update this driver (which is now marked as legacy)
have failed due to lack of testing. I am hoping that this time will be
different; Marek can test RGMII modes, but not SGMII. So all that we
know is that this patch series probably doesn't break RGMII.
1) remove unused mac_mode and sgmii flags members from structures.
2) remove unnecessary interpretation of speed when configuring 1000
and 2500 Base-X
3) move configuration of SGMII duplex setting from mac_config() to
link_up()
4) only pass in interface mode to mtk_sgmii_setup_mode_force()
5) move decision about which mtk_sgmii_setup_mode_*() function to call
into mtk_sgmii.c
6) add a fixme comment for RGMII explaning why the call to
mtk_gmac0_rgmii_adjust() is completely wrong - this needs to be
addressed by someone who has the hardware and can test an appropriate
fix. This fixme means that the driver still can't become non-legacy.
7) move gmac setup from mac_config() to mac_finish() - this preserves
the order that we write to the hardware when we eventually convert to
phylink_pcs()
8) move configuration of syscfg0 in SGMII/802.3z mode to mac_finish()
for the same reasons as (7).
9) convert mtk_sgmii.c code structure and the mtk_sgmii structure to
suit conversion to phylink_pcs
10) finally convert to phylink_pcs
As there has been no feedback from mtk_eth_soc maintainers to my RFC
on April 6th, not my reminder on April 11th, so it's now time to merge
this anyway. Mediatek code seems to be submitted to the kernel and
then the maintainers scarper...

clang emits a -Wunaligned-access warning on union
mcp251xfd_tx_ojb_load_buf.
The reason is that field hw_tx_obj (not declared as packed) is being
packed right after a 16 bits field inside a packed struct:
| union mcp251xfd_tx_obj_load_buf {
| struct __packed {
| struct mcp251xfd_buf_cmd cmd;
| /* ^ 16 bits fields */
| struct mcp251xfd_hw_tx_obj_raw hw_tx_obj;

| struct mcp251xfd_hw_tx_obj_raw hw_tx_obj;
| __be16 crc;
| } crc;
| } ____cacheline_aligned;
Starting from LLVM 14, having an unpacked struct nested in a packed
struct triggers a warning. c.f. [1].
This is a false positive because the field is always being accessed
with the relevant put_unaligned_*() function. Adding __packed to the
structure declaration silences the warning.

We want to remove the weight argument from the basic version of the
netif_napi_add() call. Move all the callers in drivers/net/can that
pass a custom weight (i.e. not NAPI_POLL_WEIGHT or 64) to the
netif_napi_add_weight() API.

With commit 2aa39889c4 ("can: isotp: isotp_bind(): return -EINVAL on
incorrect CAN ID formatting") the bind() syscall returns -EINVAL when
the given CAN ID needed to be sanitized. But in the case of an unconfirmed
broadcast mode the rx CAN ID is not needed and may be uninitialized from
the caller - which is ok.
This patch makes sure the result of an inproper CAN ID format is only
provided when the address information is needed.

TLS device offload copies sendfile data to a bounce buffer before
transmitting. It allows to maintain the valid MAC on TLS records when
the file contents change and a part of TLS record has to be
retransmitted on TCP level.
In many common use cases (like serving static files over HTTPS) the file
contents are not changed on the fly. In many use cases breaking the
connection is totally acceptable if the file is changed during
transmission, because it would be received corrupted in any case.
This commit allows to optimize performance for such use cases to
providing a new optional mode of TLS sendfile(), in which the extra copy
is skipped. Removing this copy improves performance significantly, as
TLS and TCP sendfile perform the same operations, and the only overhead
is TLS header/trailer insertion.
The new mode can only be enabled with the new socket option named
TLS_TX_ZEROCOPY_SENDFILE on per-socket basis. It preserves backwards
compatibility with existing applications that rely on the copying
behavior.
The new mode is safe, meaning that unsolicited modifications of the file
being sent can't break integrity of the kernel. The worst thing that can
happen is sending a corrupted TLS record, which is in any case not
forbidden when using regular TCP sockets.
Sockets other than TLS device offload are not affected by the new socket
option. The actual status of zerocopy sendfile can be queried with
sock_diag.
Performance numbers in a single-core test with 24 HTTPS streams on
nginx, under 100% CPU load:
* non-zerocopy: 33.6 Gbit/s
* zerocopy: 79.92 Gbit/s

Current implementation of ct merging doesn't support the case
that the fields mangling in pre_ct rules are matched in post_ct
rules.
This change is to support merging when mangling mac address,
ip address, tos, ttl and l4 port. VLAN and MPLS mangling is
not involved yet.
