#ifndef _NETINET6_IN6_PCB_H_
#define _NETINET6_IN6_PCB_H_
Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL" is an application space macro and the applications are supposed to be free to use it as they please (but cannot). This is consistant with the other BSD's who made this change quite some time ago. More commits to come.

Modify in6_pcbpurgeif0() to accept a pcbinfo structure rather than a pcb list head structure; this improves congruence to IPv4, and also allows in6_pcbpurgeif0() to lock the pcbinfo. Modify in6_pcbpurgeif0() to lock the pcbinfo before iterating the pcb list, use queue(9)'s LIST_FOREACH() for the iteration, and to lock individual inpcb's while manipulating them.

void in6_pcbdetach __P((struct inpcb *));
void in6_pcbdisconnect __P((struct inpcb *));
Break out in_pcbdetach() into two functions: - in_pcbdetach(), which removes the link between an inpcb and its socket. - in_pcbfree(), which frees a detached pcb. Unlike the previous in_pcbdetach(), neither of these functions will attempt to conditionally free the socket, as they are responsible only for managing in_pcb memory. Mirror these changes into in6_pcbdetach() by breaking it into in6_pcbdetach() and in6_pcbfree(). While here, eliminate undesired checks for NULL inpcb pointers in sockets, as we will now have as an invariant that sockets will always have valid so_pcb pointers. MFC after: 3 months

Pass pcbinfo structures to in6_pcbnotify() rather than pcbhead structures, allowing in6_pcbnotify() to lock the pcbinfo and each inpcb that it notifies of ICMPv6 events. This prevents inpcb assertions from firing when IPv6 generates and delievers event notifications for inpcbs. Reported by: kuriyama Tested by: kuriyama

Notify functions can destroy the pcb, so they have to return an indication of whether this happenned so the calling function knows whether or not to unlock the pcb. Submitted by: Jennifer Yang (yangjihui@yahoo.com) Bug reported by: Sid Carter (sidcarter@symonds.net)

Create new functions in_sockaddr(), in6_sockaddr(), and in6_v4mapsin6_sockaddr() which allocate the appropriate sockaddr_in* structure and initialize it with the address and port information passed as arguments. Use calls to these new functions to replace code that is replicated multiple times in in_setsockaddr(), in_setpeeraddr(), in6_setsockaddr(), in6_setpeeraddr(), in6_mapped_sockaddr(), and in6_mapped_peeraddr(). Inline COMMON_END in tcp_usr_accept() so that we can call in_sockaddr() with temporary copies of the address and port after the PCB is unlocked. Fix the lock violation in tcp6_usr_accept() (caused by calling MALLOC() inside in6_mapped_peeraddr() while the PCB is locked) by changing the implementation of tcp6_usr_accept() to match tcp_usr_accept().

Reduce network stack oddness: implement .pru_sockaddr and .pru_peeraddr protocol entry points using functions named proto_getsockaddr and proto_getpeeraddr rather than proto_setsockaddr and proto_setpeeraddr. While it's true that sockaddrs are allocated and set, the net effect is to retrieve (get) the socket address or peer address from a socket, not set it, so align names to that intent.
