Hi guys,

While hoping to test vserver on 2.5 (which includes USAGI - but
unfortunately not vserver yet) at some point :) I'm trying to patch my
2.4.20 kernel with Usage (www.linux-ipv6.org) and cryptoapi.

I've got my kernel patched with usage, and cryptoapi - but vserver
fails:

</snippet of output>

when looking in tcp_ipv4.c I find that the patch #hunk 2:

*** 201,207 ****
                            !sk2->reuse ||
                            sk2->state == TCP_LISTEN) {
! if (!sk2->rcv_saddr ||
! !sk->rcv_saddr ||
! (sk2->rcv_saddr == sk->rcv_saddr))
                                        break;
                        }
--- 251,255 ----
                            !sk2->reuse ||
                            sk2->state == TCP_LISTEN) {
! if (tcp_ipv4_addr_conflict(sk,sk2))
                                        break;
                        }
***************

the line sk2->state == TCP_LISTEN is nowhere to be found in tcp_ipv4
(since the USAGI patch was applied) so I'm at a loss, to figure out a
way to get USAGI and vserver working together on 2.4.20.

I was hoping perhaps any of you had suggestions? Perhaps any you would
like a kernel that supports IPV6 (including IPSEC - which the current
2.4 ipv6 doesn't - which is also probably why USAGI went in to the 2.5
kernel) and vserver :)

Thank you for just reading this far ;)
