Revision 1.50 stated that it fixed the -iface breakage introduced with
the latest KAME merge in revision 1.48. Actually, revision 1.48 fixed
the bug in revision 1.12 which incorrectly tested the ifr_flags member
of the ifreq structure filled by ioctl(SIOCGIFCONF); ifr_flags is only
valid in the SIOCGIFFLAGS case.
But yes, we still want to be able to specify the interface name as the
gateway for non-P2P interfaces.
(e.g., on alphas, or even on i386's with a POSIX-200x-conformant
ntohl() (ntohl() returns uint32_t which is u_int on i386's)).
Fixed related bugs and bogons while I'm here:
- ntohl() was "fixed" for printing in 1 place by casting to
"(unsigned int )". This breaks the value on systems where u_int
is smaller than uint32_t, and has 2 style bugs.
- spell u_int consistently (never use "unsigned").
- break K&R support some more (don't cast malloc()'s arg to a wrong
type...).
Replace the a.out emulation of 'struct linker_set' with something
a little more flexible. <sys/linker_set.h> now provides macros for
accessing elements and completely hides the implementation.
The linker_set.h macros have been on the back burner in various
forms since 1998 and has ideas and code from Mike Smith (SET_FOREACH()),
John Polstra (ELF clue) and myself (cleaned up API and the conversion
of the rest of the kernel to use it).
The macros declare a strongly typed set. They return elements with the
type that you declare the set with, rather than a generic void *.
For ELF, we use the magic ld symbols (__start_<setname> and
__stop_<setname>). Thanks to Richard Henderson <rth@redhat.com> for the
trick about how to force ld to provide them for kld's.
For a.out, we use the old linker_set struct.
NOTE: the item lists are no longer null terminated. This is why
the code impact is high in certain areas.
The runtime linker has a new method to find the linker set
boundaries depending on which backend format is in use.
linker sets are still module/kld unfriendly and should never be used
for anything that may be modular one day.

with BDECFLAGS on, mainly by adding 'const' to parameters in a number
of routine declarations. While I'm at it, ANSI-fy all of the routine
declarations. The resulting object code is exactly the same after
this update as before it, with the exception of one unavoidable
change to lpd.o on freebsd/alpha.
Also added $FreeBSD$ line to lpc/extern.h lpc/lpc.h lptest/lptest.c

in revision 1.48. It is pretty valid and often feasible to use
a non-point-to-point interface as the gateway. One might, for
example, use this to route some hosts through an ARP on a local
interface, without having to assign an additional IP address:

- Replace some very poorly thought out API hacks that should have been
fixed a long while ago.
- Provide some much more flexible search functions (resource_find_*())
- Use strings for storage instead of an outgrowth of the rather
inconvenient temporary ioconf table from config(). We already had a
fallback to using strings before malloc/vm was running anyway.
this is not strictly compliant with XSI curses, it enables us to pass
const strings to many more functions that are actually const safe than
before. This should be harmless.
Requested by: lots of folks
of calling sigprocmask(). This matches the behaviour of thr_sigsetmask()
on Solaris; _pthread_sigmask_stub was added purely for compatibility
with Solaris (for TI-RPC), so it might as well do the same thing.
This fixes the problem where client RPC calls ignored all signals
for the complete duration of the RPC. This behaviour is currently
necessary in the threaded case due to locking issues, but was never
intended to occur in non-threaded programs.

- add a pointer to struct mauxtag. two integer was too restrictive
- have m_aux_{add,find}2.
- make sure to return non-cluster on m_pulldown(). this is safer
(but of course less performant) when we have non-loopback L2 code
which throws the mbuf back to input path, like L2 bridging or some
multicast handling code.
Following changed was made by previous commit:
- add a pointer to struct mauxtag. two integer was too restrictive.
- add m_aux_{add,find}2.
- make sure to nuke mbuf pointed to m_aux.
- do not assume that the ro_dst member of route_in6{} is sockaddr_in6.
- repair IPsec header size prediction.
- validate mbuf chain better in {tcp,udp}6_ctlinput.
- loosened validation inner packets of icmp6 errors as much as possible.
- scope-awareness.
- be friendly with pfctlinput2.
- simplified address scope handling in the ctlinput function.
- type change of in6_pcbnotify.
- pass error from ipsec_setsocket() all the way up.
- added comments about why in6p_inputopts should not be copied in
tcp6_input().
- call ip6_copypktopts() in order to copy in6p_outputopts
from a listening PCB to a corresponding accepting one.
- be proactive about unspecified IPv6 source address. pcb layer
uses unspecified address (::) to mean "unbounded" or
"unconnected", and can be confused by packets from outside.
- made consist between tcp and udp in using mappedaddr
- setsockopt(BIND_IPV6ONLY) now works
- deprecated address consideration on TCP SYN.
- get rid of M_ANYCAST6
