PR/57609: Carl Engvall: Add salen checks but accept larger sizes
(upto sockaddr_storage)

be more forgiving, and don't abort on unexpected errors.

Handle herrors properly so that postfix can return 4XX codes when appropriate.
Pointed out by Viktor Dukhovni.

PR/50195: Henning Petersen: Incorrect check in getnameinfo_link.

Don't create a weak alias in the !RUMPACTION case.

Fix rump.{netstat,route} shows host's interface names in link local addresses

Interface names of IPv6 link local addresses are resolved
by getnameinfo(3). So we need to rump-ify it as well as
if_indextoname and getifaddrs.

Add not advertised reentrant functions: {get,set,end}hostent_r,
gethostbyname{,2}_r, gethostbyaddr_r. Make getnameinfo(3) use
gethostbyaddr_r(3) so it is re-entrant (ahem __ypdomain). These
are not being advertised because there is a bunch of different
implementation of them that have a variety of type signatures.

If people want to follow someone's implementation, it is now easy.

add and document AF_LOCAL (and the rest that were not)

PR/45989: Martin Husemann: lint invocation does include -w only on i386

- turn lint -w for all the platforms after fixing the lint warnings.
- add _DIAGASSERTS() for casts that would assign values to types that
would not fit.
- change types, add casts
- change into ansii prototypes
- turn on _DIAGNOSTIC for libc (during current, to be eliminated for release
builds)

Print AppleTalk phase 2 range, too, if available.

Add AF_APPLETALK support to getnameinfo(); make "route show" use it.
Doesn't print "ranges" yet (should it be done here?); only numeric
output.

Watch getservbyport_r() semantics. sv needs scope
while results are being looked at which in turn
are no longer valid after a endservent_r().

Return EAI_OVERFLOW instead of EAI_MEMORY when the supplied buffer is
too short. This conforms to RFC3493, POSIX and XPG6. [from KAME]

WARNS=4

Fix signed/unsigned comparison warnings. Catch error conditions
from snprintf().

correct %d/%u mixup.

Turn the flags argument to getnameinfo(3) back into an int (from unsigned
int); this is consistent with RFC2553, the current draft-ietf-ipngwg-
rfc2553bis-05 and the majority of deployed implementations.

Also, there is an effort under way to have this changed back to int in
XBD6/XSH6, XNS, and POSIX-2001 TC1.

use strlcpy, not strcpy

branches: 1.37.2;
More XNS5.2/POSIX-2001 alignment: change the flags argument to
getnameinfo() from int to unsigned int.

Align with XNS5.2/POSIX-2001: change hostlen and servlen arguments to
getnameinfo() from size_t to socklen_t.

More ipip references

make NI_WITHSCOPEID a default (always on), to synchronize with recent 2553bis.
sync with kame.

synchronize with kame better. get rid of #defines for ENI_xx.

Put back AF_LINK support. This time, all the new code passes lint(1), modulo
bin/14175. It should pass lint on a native i386 build, but I can't test that.

Remove AF_LINK support. It generates lint warnings, and hence won't compile
on i386. I'll re-commit once I've understood and fixed the problems.

make it at least compile (there's no /usr/include/net/if_ieee1394.h exist).
avoid overrun with snprintf. be careful about snprintf return value.

Extend getnameinfo() to support AF_LINK sockaddrs. The intention is that
anything that wants to print a link-layer address should go through here,
rather than re-inventing the wheel.

snprintf return value audit. inspired by deraadt

to synchronize with progress of discussion for post

use "address%interface" notation for extended scoped IPv6 address.

NOTE: the change affects link-local addresses only. I hope it to be
the final change on it.....

preparation to flip extended scoped address syntax.

the specification is still under debate; there is high possibility that
"fe80::1%de0" will be the finalist but i'm not sure yet.

revise extended scoped address format support. delimiter and the order
is changed, based on discussion in ipngwg scoped address cabal.
past code: fe80::1@de0
now: de0%fe80::1
this will be in sync with next extended address format proposal
(which should be final - I don't want to make this kind of change again).

Partially delint.

remove #if 0'ed sections.

allow reverse query for v4 loopbacknet (127.0.0.0/8).

fix getaddrinfo(3) and getnameinfo(3).

getaddrinfo(3): result from gethostby* will be broken if we call it again.
deep-copy them. we have sa_len so configure them.
getnameinfo(3): we have sa_len so configure them.

bring in latest KAME get{addr,name}info(3).
getnameinfo(3) globs ai_socktype and ai_protocol correctly.
KAME scopeid extension is implemented.

bump up shlib minor

ai_flags)

branches: 1.4.4;
Need "namespace.h".

- provide reverse query for mapped address (::ffff:10.1.1.1).
- NI_NUMERICHOST and NI_HOSTREQD conflict with each other,
so bark if there are both.
(sync with recent KAME)

add NetBSD RCSID on top.

add IPv6 support functions.

get{addr,name} info are implemented to have as little impact to existing
resolver code as possible, so they are NOT the optimal implementation.
They are at this moment not very thread safe (as they call
gethostby{name,addr}).

(shlib minor version)++, as new interfaces are added.

TODO: getipnodeby{name,addr} - which needs total reimplementation of
gethostby{name,addr}.
upgrade rcmd.c for multiple af support (needed for IPv6-ready rsh/rlogin)
