2020-01-10devlink: rename devlink-info-versions.rst and add a headerJacob Keller3-65/+95
Rename the devlink-info-versions.rst file to a plain devlink-info.rst file.

2020-01-09tcp: clean ext on tx recyclePaolo Abeni1-0/+1
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.

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: 9424e2e7ad93 (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.

2020-01-09tcp: coalesce/collapse must respect MPTCP extensionsMat Martineau4-4/+74
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: Paolo Abeni <pabeni@redhat.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: Mat Martineau <mathew.j.martineau@linux.intel.com> Signed-off-by: David S.

2020-01-09tcp, ulp: Add clone operation to tcp_ulp_opsMat Martineau2-0/+17
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 <mathew.j.martineau@linux.intel.com> Signed-off-by: David S.

2020-01-09tcp: Define IPPROTO_MPTCPMat Martineau3-1/+6
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.
