new GCC_NO_* uses for warning issues. most of the users of the new
GCC_NO_RETURN_LOCAL_ADDR are bugs in GCC itself, not the code.

introduce some common variables for use in GCC warning disables:

GCC_NO_FORMAT_TRUNCATION -Wno-format-truncation (GCC 7/8)
GCC_NO_STRINGOP_TRUNCATION -Wno-stringop-truncation (GCC 8)
GCC_NO_STRINGOP_OVERFLOW -Wno-stringop-overflow (GCC 8)
GCC_NO_CAST_FUNCTION_TYPE -Wno-cast-function-type (GCC 8)

use these to turn off warnings for most GCC-8 complaints. many
of these are false positives, most of the real bugs are already
commited, or are yet to come.


we plan to introduce versions of (some?) of these that use the
"-Wno-error=" form, which still displays the warnings but does
not make it an error, and all of the above will be re-considered
as either being "fix me" (warning still displayed) or "warning
is wrong."

Specify "-fno-tree-ter" to getaddrinfo.c and gethnamaddr.c on arm and gcc45
for workaround of a possible optimazation bug.

On my W-ZERO3 and Zaurus, hostname lookup against CNAME by some commands
(ping(8), ftp(1) etc.) fails even though nslookup(8) returns a proper name
against the same CNAME, after NetBSD/arm ports has been switched to
gcc 4.5 since 201110311420Z (i.e 201110310000Z binaries worked but
201111010000Z ones not).

Building getaddrinfo.c and gethnamaddr.c in libc with "-O2 -fno-tree-ter"
(or using objects built by old gcc 4.1) seems to fix this issue.

Accroding to nonaka@, the following gcc bugzilla test case also fails
with -O2 but works with -O2 -fno-tree-ter on NetBSD/zaurus 5.99.57:

to get (f)lex output to go to stdout, use -t (a flag supported by
flex) rather than -o/dev/stdout which uses a flex feature (-o isn't
in vendor lex, at least on solaris 7) and also requires that
"/dev/stdout" function in the expected manner.

use BSDI-origin if_{index,name}* functions. they use getifaddrs(3) as
backend and are more robust against SIOCGIFCONF alignment issue.
now getifaddrs always takes care of the issue. (sync with kame tree)
use weak symbol just in case.

Listing generated files nslexer.c nsparser.c in SRCS breaks make depend

make CMSG_ALIGN always synchronize with kernel's idea of ALIGNBYTES.

NOTE: if you are on top of arch with ALIGNBYTES != sizeof(long) - 1,
you need to recompile IPv6-related binaries. there is no way to guarantee

As a consequence, bump libc's minor number.

Document the LOCAL_PEEREID socket option in unix(4).

Based on contribution by Arne H. Juul, minor modifications by myself.

Remove the XNS man pages.

Move ns_addr and ns_ntoa to compat libc. Add a stripped version of
<netns/ns.h> which only include struct ns_addr and the ns_addr and ns_ntoa
function prototypes.

Add support for RFC 3542 Adv. Socket API for IPv6 (which obsoletes 2292).
* RFC 3542 isn't binary compatible with RFC 2292.
* RFC 2292 support is on by default but can be disabled.
* update ping6, telnet and traceroute6 to the new API.

From the KAME project (www.kame.net).
Reviewed by core.

replace with written-from-scratch manpage. (fixes ISOC copyright issue)

Only compile in IPv6 support if ${USE_INET6} != "no"

MKINET6 is for providing IPv6 infrastructure.
USE_INET6 is for compiling IPv6 support into the programs (needs MKINET6).

revert previous change while discussion is in progress.

RFC cannot be used as manpage regarding to the ISOC copyright boilerplate.
remove it until someone writes it up from scratch/freely-redistributable
text is found.

Add MLINK for gethostent as suggested by Matthias Drochner.

Finish bind9 resolver merge.

Make building IPv6 support controllable by MKINET6

MAKEVERBOSE tweaks

Split the notion of building Hesiod, Kerberos, S/key, and YP
infrastructure and using that infrastructure in programs.

* MKHESIOD, MKKERBEROS, MKSKEY, and MKYP control building
of the infratsructure (libraries, support programs, etc.)

* USE_HESIOD, USE_KERBEROS, USE_SKEY, and USE_YP control
building of support for using the corresponding API
in various libraries/programs that can use it.

As discussed on tech-toolchain.

Add a sockatmark(3), the 1003.1g wrapper around SIOCATMARK.

remove obsolete MAN lines for getipnodeby* (has been comented out)

branches: 1.56.2;
it seems that gethostent(3) is no longer supplied in libc.
couple of wording corrections.
From: Hubert Feyrer <hubert.feyrer@informatik.fh-regensburg.de>

to get (f)lex output to go to stdout, use -t (a flag supported by
flex) rather than -o/dev/stdout which uses a flex feature (-o isn't
in vendor lex, at least on solaris 7) and also requires that
"/dev/stdout" function in the expected manner.

use BSDI-origin if_{index,name}* functions. they use getifaddrs(3) as
backend and are more robust against SIOCGIFCONF alignment issue.
now getifaddrs always takes care of the issue. (sync with kame tree)
use weak symbol just in case.

Listing generated files nslexer.c nsparser.c in SRCS breaks make depend
in a clean dir. Put the actual src files nslexer.l nsparser.y there.

make CMSG_ALIGN always synchronize with kernel's idea of ALIGNBYTES.
ancillary data alignment will be ALIGNBYTES, not sizeof(long) - 1, from now.

CMSG_xx will NOT resolve into constant. if you use CMSG_xx to allocate
arrays, you'll lose.

bump shlib minor for libc.

NOTE: if you are on top of arch with ALIGNBYTES != sizeof(long) - 1,
you need to recompile IPv6-related binaries. there is no way to guarantee
backward compat in this aspect. sorry for this. this should be the last
backward compat breakage for IPv6-related ancillary data manipulation.
(we still have PR 9516 for unix-domain sockets...)

add freeifaddrs.3 as MLINKS.

add getifaddrs(3) from bsdi4, as mentioned in tech-net (in SIOCGIFCONF
related thread).
this will save future apps from complexity of SIOCGIFCONF.

getifaddrs(3) does not use SIOCGIFCONF internally, it uses sysctl.

add missing manpage, gethostbyname2(3).

add IPv6 support to rcmd() and friends.
rcmd() and iruserok(): unchanged
ruserok(): became address family independent
rcmd_af(), iruesrok_sa(): address family independent

move -DINET6 upwards, into lib/libc/Makefile.
- we need it for lib/libc/rpc soon
- this is not clear to add CPPFLAGS in subdir/Makefile.inc (as it affect other
subdirs as well)

add manpage for inet6_{option,rthdr}_*.

add freeaddrinfo(3) and gai_strerror(3) as links to getaddrinfo(3)

branches: 1.44.4;
Add indirect reference stubs for inet_[ap]ton() for environments not supporting
weak aliases; addresses PR lib/7435 but leaves the original file intact.

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)

Do a lame hack to reduce the size of the lexer state buffer, which reduces
memory consumption substantially. The buffer is only used to print line
numbers...

branches: 1.41.2;
use ${ARCHDIR} instead of ${.CURDIR}/arch/${MACHINE_ARCH} where appropriate
libc builds on pmax again

add hesiod(3) et al

pull nsswitch up to main branch
convert getnetby*() to nsswitch (from resolv.conf lookup)

merge nsswitch into main branch

install links for inet_ntop(3) and inet_pton(3)

Add sorting of resolved addresses.

add missing .Nm entries. from spz@serpens.swb.de.

branches: 1.34.2;
Make linkntoa.3 a link to linkaddr.3 again; fixes PR lib/4017 from maximum
entropy <entropy@tardis.bernstein.com>.

merge bind 4.9.6 resolver. still need to fix <resolv.h>

inet_pton4() did not handle
- incompletely specified ip addresses
- ip addresses specified in hex
like inet_aton() and inet_addr(). This broke parsing of /etc/hosts
(127.1 localhost stopped working before the resolver is started).
The fix is to use the inet_aton() code to implement inet_pton4(), and
then use the new inet_pton4() code to implement inet_aton() and inet_addr().
At that point inet_addr.c is empty and has been removed.

* add man page for inet_net_ntop(3) and inet_net_pton(3)
* xref them in inet(3)
* use Va instead of Fn for 'errno' in inet(3)

install a man page (link) for orcmd(3).

branches: 1.29.2;
create indirect references (or function stubs) to dn_comp(), res_close()
and res_send(), as required.

merge in the bind 4.9.5-P1 resolver. we are now _mostly_ the
same as this, with our changes also included (resolv.conf and
other minor differences).

Add iso_addr.3 to MAN. Fixes misc/2942.

branches: 1.26.4;
Install linkaddr.3 as link_addr.3 and link_ntoa.3 too.

Added explicit return types to all functions in SYNOPSIS section.
Added documentation to hstrerror() function.
Added hstrerror MLINK.

merge with the resolver in bind 4.9.3-P1.
