faf391c382 tcp: Define IPPROTO_MPTCP
To open a MPTCP socket with socket(AF_INET, SOCK_STREAM, IPPROTO_MPTCP),
IPPROTO_MPTCP needs a value that differs from IPPROTO_TCP. The existing
IPPROTO numbers mostly map directly to IANA-specified protocol numbers.
MPTCP does not have a protocol number allocated because MPTCP packets
use the TCP protocol number. Use private number not used OTA.

bf9765145b sock: Make sk_protocol a 16-bit value
Match the 16-bit width of skbuff->protocol. Fills an 8-bit hole so
sizeof(struct sock) does not change.

Also take care of BPF field access for sk_type/sk_protocol. Both of them
are now outside the bitfield, so we can use load instructions without
further shifting/masking.

v5 -> v6:
 - update eBPF accessors, too (Intel's kbuild test robot)
v2 -> v3:
 - keep 'sk_type' 2 bytes aligned (Eric)
v1 -> v2:
 - preserve sk_pacing_shift as bit field (Eric)

e9cdced78d net: Make sock protocol value checks more specific
SK_PROTOCOL_MAX is only used in two places, for DECNet and AX.25. The
limits have more to do with the those protocol definitions than they do
with the data type of sk_protocol, so remove SK_PROTOCOL_MAX and use
U8_MAX directly.

mlxsw: Firmware version updates

This patch sets contains two firmware-related updates.

Patch #1 bumps the required firmware version in order to support 2x50
Gb/s split on SN3800 systems.

Patch #2 changes the driver to only enforce a minimum required firmware
version, which should allow us to reduce the frequency in which we need
to update the driver.

4dab08df3b mlxsw: spectrum: Only require minimum firmware version
Currently, the driver ensures that the firmware version found on the
device matches the branch of the required version.

Remove this limitation so that the driver will accept the required
version or a newer version, from any branch.

This will allow us to reduce the frequency in which we need to update
the required version. New firmware versions that include necessary bug
fixes will be able to work with the driver, even if they are not from
the required branch.

78b6d073bc Merge branch 'Broadcom-tags-support-for-531x5-539x-families'
Florian Fainelli says:

====================
Broadcom tags support for 531x5/539x families

This patch series finally allows us to enable Broadcom tags on the
BCM531x5/BCM539x switch series which are very often cascaded onto
another on-chip Broadcom switch. Because of that we need to be able to
detect that Broadcom tags are already enabled on our DSA master which
happens to be a DSA slave in that case since they are not part of the
same DSA switch tree, the protocol does not support that.

Due to the way DSA works, get_tag_protocol() is called prior to
ds->ops->setup and we do not have all data structures set-up (in
particular dsa_port::cpu_dp is not filed yet) so doing this at the time
get_tag_protocol() is called and without exporting a helper function is
desirable to limit our footprint into the framework.

Having the core (net/dsa/dsa2.c) return and enforce DSA_TAG_PROTO_NONE
was considered and done initially but this leaves the driver outside of
the decision to force/fallback to a particular protocol, instead of
letting it in control. Also there is no reason to suspect that all
tagging protocols are problematic, e.g.: "inner" Marvell EDSA with
"outer" Broadcom tag may work just fine, and vice versa.

This was tested on:

- Lamobo R1 which now has working Broadcom tags for its external BCM53125 switch
- BCM7445 which has a BCM53125 hanging off one of its internal switch
  port, the BCM53125 still works with DSA_TAG_PROTO_NONE
- BCM7278 which has a peculiar dual CPU port set-up (so dual IMP mode
  needs to be enabled)
- Northstar Plus with DSA_TAG_PROTO_BRCM_PREPEND and no external
  switches hanging off the internal switch

8fab459e69 net: dsa: b53: Enable Broadcom tags for 531x5/539x families
The BCM531x5 and BCM539x families require that the IMP port be enabled
within the management page and that management mode (SM_SW_FWD_MODE) be
turned on. Once this is done, everything works as expected, including
multicast with standalone DSA devices or bridge devices.

Because such switches are frequencly cascaded with other internal
Broadcom switches on which we want to enable Broadcom tags, update
b53_can_enable_brcm_tags() to check the kind of DSA master tagging
protocol being used, if it is one of the two supported Broadcom tagging
protocols, force DSA_TAG_PROTO_NONE.

4d776482ec net: dsa: Get information about stacked DSA protocol
It is possible to stack multiple DSA switches in a way that they are not
part of the tree (disjoint) but the DSA master of a switch is a DSA
slave of another. When that happens switch drivers may have to know this
is the case so as to determine whether their tagging protocol has a
remove chance of working.

This is useful for specific switch drivers such as b53 where devices
have been known to be stacked in the wild without the Broadcom tag
protocol supporting that feature. This allows b53 to continue supporting
those devices by forcing the disabling of Broadcom tags on the outermost
switches if necessary.

The get_tag_protocol() function is therefore updated to gain an
additional enum dsa_tag_protocol argument which denotes the current
tagging protocol used by the DSA master we are attached to, else
DSA_TAG_PROTO_NONE for the top of the dsa_switch_tree.

9546a0b7ce tipc: fix wrong connect() return code
The current 'tipc_wait_for_connect()' function does a wait-loop for the
condition 'sk->sk_state != TIPC_CONNECTING' to conclude if the socket
connecting has done. However, when the condition is met, it returns '0'
even in the case the connecting is actually failed, the socket state is
set to 'TIPC_DISCONNECTING' (e.g. when the server socket has closed..).
This results in a wrong return code for the 'connect()' call from user,
making it believe that the connection is established and go ahead with
building, sending a message, etc. but finally failed e.g. '-EPIPE'.

This commit fixes the issue by changing the wait condition to the
'tipc_sk_connected(sk)', so the function will return '0' only when the
connection is really established. Otherwise, either the socket 'sk_err'
if any or '-ETIMEDOUT'/'-EINTR' will be returned correspondingly.

49afb806cb tipc: fix link overflow issue at socket shutdown
When a socket is suddenly shutdown or released, it will reject all the
unreceived messages in its receive queue. This applies to a connected
socket too, whereas there is only one 'FIN' message required to be sent
back to its peer in this case.

In case there are many messages in the queue and/or some connections
with such messages are shutdown at the same time, the link layer will
easily get overflowed at the 'TIPC_SYSTEM_IMPORTANCE' backlog level
because of the message rejections. As a result, the link will be taken
down. Moreover, immediately when the link is re-established, the socket
layer can continue to reject the messages and the same issue happens...

The commit refactors the '__tipc_shutdown()' function to only send one
'FIN' in the situation mentioned above. For the connectionless case, it
is unavoidable but usually there is no rejections for such socket
messages because they are 'dest-droppable' by default.

In addition, the new code makes the other socket states clear
(e.g.'TIPC_LISTEN') and treats as a separate case to avoid misbehaving.

Vikas Gupta says:

====================
Devlink notification after recovery complete by bnxt_en driver

 This patchset adds following feature in devlink
  1) Recovery complete direct call API to be used by drivers when it
     successfully completes. It is required as recovery triggered by
     devlink may return with EINPROGRESS and eventually recovery
     completes in different context.
  2) A notification when health status is updated by reporter.

 Patchset also contains required changes in bnxt_en driver to
 mark recovery in progress when recovery is triggered from kernel
 devlink.

6181e5cb75 devlink: add support for reporter recovery completion
It is possible that a reporter recovery completion do not finish
successfully when recovery is triggered via
devlink_health_reporter_recover as recovery could be processed in
different context. In such scenario an error is returned by driver when
recover hook is invoked and successful recovery completion is
intimated later.
Expose devlink recover done API to update recovery stats.

====================
reduce open coded skb->next access for gso segment walking

This patchset introduces the skb_list_walk_safe helper macro, in order
to add some sanity to the myrid ways drivers have of walking through gso
segments. The goal is to reduce future bugs commonly caused by open
coding these sorts of things, and to in the future make it easier to
swap out the underlying list representation.

This first patch series addresses the easy uses of drivers iterating
over the returned list of skb_gso_segments, for drivers that live in
drivers/net/*. There are still other use cases to tackle later for
net/*, and after these low-hanging fruits are taken care of, I imagine
there are more subtle cases of gso segment walking that isn't just a
direct return value from skb_gso_segments, and eventually this will have
to be tackled. This series is the first in that direction.
