argument to ip6_output() with a new explicit struct in6pcb* argument.
(The underlying socket can be obtained via in6pcb->inp6_socket.)
In preparation for fast-ipsec. Reviewed by itojun.
- routing header declaration with RFC3542
(note: sizeof(ip6_rthdr0) has changed!)
also, sync up with RFC2460 routing header definition (no "strict" source
routing mode any more)
part of advanced API update (RFC2292 -> 3542).
as necessary:
* Implement a new mbuf utility routine, m_copyup(), is is like
m_pullup(), except that it always prepends and copies, rather
than only doing so if the desired length is larger than m->m_len.
m_copyup() also allows an offset into the destination mbuf, which
allows space for packet headers, in the forwarding case.
* Add *_HDR_ALIGNED_P() macros for IP, IPv6, ICMP, and IGMP. These
macros expand to 1 if __NO_STRICT_ALIGNMENT is defined, so that
architectures which do not have strict alignment constraints don't
pay for the test or visit the new align-if-needed path.
* Use the new macros to check if a header needs to be aligned, or to
assert that it already is, as appropriate.
Note: This code is still somewhat experimental. However, the new
code path won't be visited if individual device drivers continue
to guarantee that packets are delivered to layer 3 already properly
aligned (which are rules that are already in use).
net.inet6.icmp6.nodeinfo is now a bitmap (2^0 = ping6 -w, 2^1 = ping6 -a).
give up local if there's mbuf alloc failures.
cope with ".." in hostname.
sync comments/whitespaces.
now traffic on loopback interface will be presented to bpf as normal wire
format packet (without KAME scopeid in s6_addr16[1]).
fix KAME PR 250 (host mistakenly accepts packets to fe80::x%lo0).
sync with kame.
normal operation (/var can get filled up by flodding bogus packets).
sysctl net.inet6.icmp6.nd6_debug will turn on diagnostic messages.
(#define ND6_DEBUG will turn it on by default)
improve stats in ND6 code.
lots of synchronziation with kame (including comments and cometic ones).
- let ipfilter look at wire-format packet only (not the decapsulated ones),
so that VPN setting can work with NAT/ipfilter settings.
sync with kame.
