Subject: [PATCH bpf-next v2 0/9] bpf: sockmap, sockhash: support storing UDP sockets
Date: Fri, 28 Feb 2020 11:53:35 +0000 [thread overview]
Message-ID: <20200228115344.17742-1-lmb@cloudflare.com> (raw)
Thanks for all the reviews so far! I've fixed the identified bug and addressed
feedback as much as possible.
I've not taken up Jakub's suggestion to get rid of sk_psock_hooks_init. My
intention is to encapsulate initializing both v4 and v6 protos. Really, it's
down to personal preference, and I'm happy to remove it if others prefer
Jakub's approach. I'm also still eager for a solution that requires less
machinery.
Changes since v1:
- Check newsk->sk_prot in tcp_bpf_clone
- Fix compilation with BPF_STREAM_PARSER disabled
- Use spin_lock_init instead of static initializer
- Elaborate on TCPF_SYN_RECV
- Cosmetic changes to TEST macros, and more tests
- Add Jakub and me as maintainers
