Currently we can allocate the extension only after the skb, this change allows the user to do the opposite, will simplify allocation failure handling from MPTCP. Signed-off-by:

Otherwise we will find stray/unexpected/old extensions value on next iteration. On tcp_write_xmit() we can end-up splitting an already queued skb in two parts, via tso_fragment(). The newly created skb can be allocated via the tx cache and an upper layer will not be aware of it, so that upper layer cannot set the ext properly. Resetting the ext on recycle ensures that stale data is not propagated in to packet headers or elsewhere. An alternative would be add an additional hook in tso_fragment() or in sk_stream_alloc_skb() to init the ext for upper layers that need it. Co-developed-by:

Update the SACK check to work with zero option space available, a case that's possible with MPTCP but not MD5+TS. Maintained only one conditional branch for insufficient SACK space. v1 -> v2: - Moves the check inside the SACK branch by taking recent SACK fix: 9424e2e7 (tcp: md5: fix potential overestimation of TCP option space) in to account, but modifies it to work in MPTCP scenarios beyond the MD5+TS corner case.

MPTCP will make use of tcp_send_mss() and tcp_push() when sending data to specific TCP subflows. tcp_request_sock_ipvX_ops and ipvX_specific will be referenced during TCP subflow creation. Co-developed-by:

Coalesce and collapse of packets carrying MPTCP extensions is allowed when the newer packet has no extension or the extensions carried by both packets are equal. This allows merging of TSO packet trains and even cross-TSO packets, and does not require any additional action when moving data into existing SKBs. v3 -> v4: - allow collapsing, under mptcp_skb_can_collapse() constraint v5 -> v6: - clarify MPTCP skb extensions must always be cleared at allocation time Co-developed-by:

If ULP is used on a listening socket, icsk_ulp_ops and icsk_ulp_data are copied when the listener is cloned. Sometimes the clone is immediately deleted, which will invoke the release op on the clone and likely corrupt the listening socket's icsk_ulp_data. The clone operation is invoked immediately after the clone is copied and gives the ULP type an opportunity to set up the clone socket and its icsk_ulp_data. The MPTCP ULP clone will silently fallback to plain TCP on allocation failure, so 'clone()' does not need to return an error code. v6 -> v7: - move and rename ulp clone helper to make it inline-friendly v5 -> v6: - clarified MPTCP clone usage in commit message Signed-off-by:

Mat Martineau authored
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. Reviewed-by:

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.

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. Reviewed-by:

Ido Schimmel says: ==================== 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. ==================== Signed-off-by: -

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. Signed-off-by:

The `connected` value for wired devices was not properly initialized, it must be set to `true` upon creation, because wired devices do not generate connection events. When a raw client (the Steam Client) uses the device, the input device is destroyed. Then, when the raw client finishes, it must be recreated. But since the `connected` variable was false this never happended. Signed-off-by:

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 ==================== Signed-off-by:
