Thank you for the patches.

I *think* everything is now sync in our tree but feel free to check
because I had to "manually" compare patches with what was in our tree.

But in theory, our tree is now ready for a v5.

- 82041505ae27: tg:msg: changelog v4
- a59272c197c5: selftests/bpf: add MPTCP test base
- e30677603c0a: Squash to "selftests/bpf: add MPTCP test base"
- 79399587d58f: tg:msg: changelog v4
- b0d947191559: selftests/bpf: verify token of struct mptcp_sock
- d84ab981b155: conflict in
t/selftests-bpf-verify-first-of-struct-mptcp_sock
- 0c8b3a796796: conflict in t/selftests-bpf-test-bpf_skc_to_mptcp_sock
- Results: 7809acd805cf..a4159e050cd2 (export)

Builds and tests are now in progress:

https://cirrus-ci.com/github/multipath-tcp/mptcp_net-next/export/20220514T112122
https://github.com/multipath-tcp/mptcp_net-next/actions/workflows/build-validation.yml?query=branch:export

Thanks Matt, but three patches still need to be updated:

Patch #4, selftests/bpf: test bpf_skc_to_mptcp_sock

if (!tcp_sk->is_mptcp) {

->

if (!is_mptcp) {

Patch #10, mptcp: add sched in mptcp_sock

 struct mptcp_sock {
 	struct inet_connection_sock	sk;
 
-	__u32		token;
-	struct sock	*first;
-	char		ca_name[TCP_CA_NAME_MAX];
+	__u32			token;
+	struct sock		*first;
+	struct mptcp_sched_ops	*sched;
+	char			ca_name[TCP_CA_NAME_MAX];
 } __attribute__((preserve_access_index));
 
->

 	__u32		token;
 	struct sock	*first;
+	struct mptcp_sched_ops *sched;
 	char		ca_name[TCP_CA_NAME_MAX];
 } __attribute__((preserve_access_index));
 

Patch #13, selftests/bpf: add bpf_first scheduler

bpf_mptcp_helpers.h

->

bpf_tcp_helpers.h

Thanks,

I did that on purpose, I thought it was clearer to read after.

Do you prefer not to change the alignment?

Thanks!

Hi Matt,

Here should be:
        if (!is_mptcp) {
not:
        if (is_mptcp) {

Otherwise, the mptcp bpf selftests failed.

I just sent a squash-to patch to fix this.

Thanks,
-Geliang

Yes, I prefer not to change the alignments, it's much easier. If we
want to change them, it's better to squash the changes into the
original patches.

Hi Matt & Mat,

I think it's better to keep the alignment of members of mptcp_sock in
bpf_tcp_helpers.h as the same as the alignment of mptcp_sock in
net/mptcp/protocol.h. So I just sent a squash-to patch in our ML to
fix this.

Anyway, bpf patches in our tree are now ready for a bpf-next v5.

Thanks,
-Geliang

These look good to replace the equivalent patches in the export branch. 
Thanks Geliang.
