Subject: [PATCH] merge sctp_opt with sctp_sock
Date: Sat, 15 Jan 2005 02:52:13 -0200 [thread overview]
Message-ID: <41E8A17D.9040307@conectiva.com.br> (raw)
[-- Attachment #1: Type: text/plain, Size: 510 bytes --]
Hi David, Sridhar,
Please take a look and if its acceptable pull from:
bk://kernel.bkbits.net/acme/connection_sock-2.6
The tricky bit here is that SCTP, to keep the existing logic,
needs a way to copy only its private area from one sock to another, so
I introduced a generic inet_sk_copy_descendant, that knows about the
inet (v4/v6) layout (wrt inet_sock and inet6_pinfo), using this and
sk->sk_prot->slab_obj_size we can copy the inet_sock descendant
private area generically.
Best Regards,
- Arnaldo

ChangeSet@1.2334, 2005-01-15 02:32:54-02:00, acme@toy.ghostprotocols.net
[SCTP] merge sctp_sock with sctp_opt
No need for two structs, follow the new inet_sock layout style.
Also introduce inet_sk_copy_descendant, to copy just the inet_sock
descendant specific area from one sock to another.
