Lost in the translation from the user space implementation was the detail that HELLO mesages must be exchanged between each node pair. As such the incoming HELLO must be replied to. Similar to the previous implementation no effort is made to prevent two Linux boxes from continuously sending HELLO messages back and forth, this is left to a follow up patch. say_hello() is moved, to facilitate the new call site.

2020-03-03net: mlxfw: Replace zero-length array with flexible-array memberGustavo A. R. Silva
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

2020-03-03devlink: remove trigger command from devlink-region.rstJacob Keller
The devlink trigger command does not exist. While rewriting the documentation for devlink into the reStructuredText format, documentation for the trigger command was accidentally merged in. This occurred because the author was also working on a potential extension to devlink regions which included this trigger command, and accidentally squashed the documentation incorrectly. Further review eventually settled on using the previously unused "new" command instead of creating a new trigger command. Fix this by removing mention of the trigger command from the documentation.

Mat Martineau says: ==================== mptcp: Improve DATA_FIN transmission MPTCP's DATA_FIN flag is sent in a DSS option when closing the MPTCP-level connection. This patch series prepares for correct DATA_FIN handling across multiple subflows (where individual subflows may disconnect without closing the entire MPTCP connection) by changing the way the MPTCP-level socket requests a DATA_FIN on a subflow and propagates the necessary data for the TCP option. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2020-03-03mptcp: Only send DATA_FIN with final mappingMat Martineau
When a DATA_FIN is sent in a MPTCP DSS option that contains a data mapping, the DATA_FIN consumes one byte of space in the mapping. In this case, the DATA_FIN should only be included in the DSS option if its sequence number aligns with the end of the mapped data. Otherwise the subflow can send an incorrect implicit sequence number for the DATA_FIN, and the DATA_ACK for that sequence number would not close the MPTCP-level connection correctly.

2020-03-03mptcp: Use per-subflow storage for DATA_FIN sequence numberMat Martineau
Instead of reading the MPTCP-level sequence number when sending DATA_FIN, store the data in the subflow so it can be safely accessed when the subflow TCP headers are written to the packet without the MPTCP-level lock held. This also allows the MPTCP-level socket to close individual subflows without closing the MPTCP connection. Signed-off-by: Mat Martineau <mathew.j.martineau@linux.intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-03-03mptcp: Check connection state before attempting sendMat Martineau
MPTCP should wait for an active connection or skip sending depending on the connection state, as TCP does. This happens before the possible passthrough to a regular TCP sendmsg because the subflow's socket type (MPTCP or TCP fallback) is not known until the connection is complete. This is also relevent at disconnect time, where data should not be sent in certain MPTCP-level connection states.

2020-03-03bpf: Add gso_size to __sk_buffWillem de Bruijn
BPF programs may want to know whether an skb is gso. The canonical answer is skb_is_gso(skb), which tests that gso_size != 0. Expose this field in the same manner as gso_segs. That field itself is not a sufficient signal, as the comment in skb_shared_info makes clear: gso_segs may be zero, e.g., from dodgy sources. Also prepare net/bpf/test_run for upcoming BPF_PROG_TEST_RUN tests of the feature.

Place phylink_start()/phylink_stop() inside dsa_port_enable() and dsa_port_disable(), which ensures that we call phylink_stop() before tearing down phylink - which is a documented requirement. Failure to do so can cause use-after-free bugs.
