9d93fce265 Locking for updates to routing table entries. Each rtentry gets a mutex
that covers updates to the contents.  Note this is separate from holding
a reference and/or locking the routing table itself.

Other/related changes:

o rtredirect loses the final parameter by which an rtentry reference
  may be returned; this was never used and added unwarranted complexity
  for locking.
o minor style cleanups to routing code (e.g. ansi-fy function decls)
o remove the logic to bump the refcnt on the parent of cloned routes,
  we assume the parent will remain as long as the clone; doing this avoids
  a circularity in locking during delete
o convert some timeouts to MPSAFE callouts

Notes:

1. rt_mtx in struct rtentry is guarded by #ifdef _KERNEL as user-level
   applications cannot/do-no know about mutex's.  Doing this requires
   that the mutex be the last element in the structure.  A better solution
   is to introduce an externalized version of struct rtentry but this is
   a major task because of the intertwining of rtentry and other data
   structures that are visible to user applications.
2. There are known LOR's that are expected to go away with forthcoming
   work to eliminate many held references.  If not these will be resolved
   prior to release.
3. ATM changes are untested.

22256e113b Enable IPv6 for Token Ring. 2003-09-14 02:32:31 +00:00

324045a3c2 introduced a flag bit "ND6_IFF_ACCEPT_RTADV" in the nd_ifinfo structure to
control whether to accept RAs per-interface basis.
the new stuff ensures the backward compatibility;
- the kernel does not accept RAs on any interfaces by default.
- since the default value of the flag bit is on, the kernel accepts RAs
  on all interfaces when net.inet6.ip6.accept_rtadv is 1.

7bf004382f - In nd6_rtrequest(), ignored a route when it is created by cloning and
is not a neighbor.  see comments for the detailed reason.

- Rejected the process of nd6_rtrequest() when the request is RESOLVE and
the interface does not need neighbor caches.

ecb4d3d05f Pull post-4.4BSD change to sys/net/route.c from BSD/OS 4.2.
Have sys/net/route.c:rtrequest1(), which takes ``rt_addrinfo *''
as the argument.  Pass rt_addrinfo all the way down to rtrequest1
and ifa->ifa_rtrequest.  3rd argument of ifa->ifa_rtrequest is now
``rt_addrinfo *'' instead of ``sockaddr *'' (almost noone is
using it anyways).

Benefit: the following command now works.  Previously we needed
two route(8) invocations, "add" then "change".
# route add -inet6 default ::1 -ifp gif0

Remove unsafe typecast in rtrequest(), from ``rtentry *'' to
``sockaddr *''.  It was introduced by 4.3BSD-Reno and never
corrected.

f729fe0a4a Wrap array accesses in macros, which also happen to be lvalues:
ifnet_addrs[i - 1]  -> ifaddr_byindex(i)
        ifindex2ifnet[i]    -> ifnet_byindex(i)

This is intended to ease the conversion to SMPng.

832f8d2249 Sync with recent KAME.
This work was based on kame-20010528-freebsd43-snap.tgz and some
critical problem after the snap was out were fixed.
There are many many changes since last KAME merge.

TODO:
  - The definitions of SADB_* in sys/net/pfkeyv2.h are still different
    from RFC2407/IANA assignment because of binary compatibility
    issue.  It should be fixed under 5-CURRENT.
  - ip6po_m member of struct ip6_pktopts is no longer used.  But, it
    is still there because of binary compatibility issue.  It should
    be removed under 5-CURRENT.
