this changes function prototype for __ivalid*.
This commit breaks binary compatibility for __ivalid*. I believe this can be
forgiven due to the following:
- this is not really exported function. no function prototype is in headers.
function name starts with underbars. No third-party applications are
expected to use it.
- the function was introduced very recently, when rcmd.c was made IPv6-ready.
- the only customer in NetBSD tree is lpd.
(lpd.c) sync with rcmd.c change.
on each of them, and don't bother listening on them. this allows messages
to be forwarded even with -s enabled.
XXX: not 100% sure if this is susceptable to a DoS, e.g someone filling
up kernel buffers with a backlog of packets not being read, but shutdown(2)
should prevent that even if it possibly doesn't at this time.
* minor KNF
dev/vndvar.h or dev/ccdvar.h so that struct pool is always available
regardless of multiple inclusion. Actually, ccdconfig.c compiles without
this change but ...
per mount point, the way ``try to export and unexport an unnecessary
mount point later'' may leave unwanted information in the kernel, and
doesn't work if a mount point is default exported or publically exported.
To fix the race condtion, we need another way.
version 0 RMT protocol, the query of status makes no sense (send back, in
binary, the mtget structure), but systems sometimes use it anyway. And when
they use it, they get upset if they get back something that is a different
size from what they expect. The original mtget structure in BSD 4.3 is
24 bytes in size, and that seems to be what they can cope with.
The correct fix would be to go to Version 1 RMT, but that's a horse of
another color...
one set of code which knows how to resize the packet.
Report when we shrink MTU because of an EMSGSIZE return; fix
formatting to let this not look ugly.
Add a few likely MTU's to the table (1480 and 1280).
have a way to embed the revision number into the kernel's "uname -v"
output. The patch below does this, by generating a new keyword "ident"
that can be followed by any string, e.g.
ident "NOON-$Revision$"
will lead to
vvvvvvvvvvvvvvvvvvvvvv
char version[] = "NetBSD 1.4P (NOON-$Revision: 1.21 $) #37: Thu Jan
20 02:01:23 MET 2000\n feyrer@noon:/usr/cvs.local/src-current/sys/arch/i386/c
ompile/NOON\n";
This will lead to a version of "MYMACHINE-$Revision$" instead of the
kernel config file name. If "ident" is not present, the current behaviour
of using the kernel config file's name as identifier is used.
Implement by writing the ident to a file ("ident") in the compile dir,
which newvers.sh will pick up for generating the ident.
Modulo some code cleanup, this gives NetBSD full wildcard support not
only in pkgsrc, but esp. for binary packages installed from local disk
and via FTP. For more information, see:

msg[]. I didn't check all the plog() call so I don't know if this overflow
is possible by a non-root user or not.
Suggested by Zdenek Salvet <salvet@ics.muni.cz> a looong time ago.
AF_INET6 wildcard listening socket. heavily documented in ip6(4).
net.inet6.ip6.bindv6only defines default value. default is 1.
"options INET6_BINDV6ONLY" removes any code fragment that supports
IPV6_BINDV6ONLY == 0 case (not defopt'ed as use of this is rare).
this allows you to disable/enable ICMPv6 node information query/reply
processing (which tells remote end the gethostname(3) setting, interface
addresses on the node, and some other things - documented in
draft-ietf-ipngwg-icmp-name-lookup* or something alike).
to test it, try ping6 -w ::1 with nodeinfo=0 and nodeinfo=1.

+ copy all files and directories in <skeldir> to new user's home
directory, not just if they begin with a '.'
+ use pax to copy files from <skeldir>, as this will allow <skeldir>
to contain directory trees as well as regular files
+ use -h arg to chown(1) in case any symlinks have been created in the
new user's home directory
+ getpwnam(3) does not set errno, so use errx(3) and warnx(3)
+ use nologin(8) in preference to false(1) when deleting users but
preserving information
+ in usage messages, specify [-r lowuid..highuid] rather than a simple
[-r range]
+ Moved all internal definitions from usermgmt.h to user.c
+ Added prototypes to usermgmt.h
+ Allow defaults to be set at build time
+ Check the effective uid is 0 if any data is to be modified
+ Check all numeric uids and gids really are numeric
+ Fix a bug (reported by lenb at sasquatch.com) where new ranges were
appended to old ranges, rather than replacing them
+ Add userinfo(8) and groupinfo(8) utilities (if EXTENSIONS is
defined), whereby user and group information can be displayed. Add
manual pages for new utilities. Add front-end calling from user(8)
and group(8) accordingly.
+ Make all functions visible outside the user.c file again. User and
group manipulation may be split out into a separate shared lib in the
future
+ Split off main function into a separate main.c
+ Changed default group to be "users"
+ Changed despatch table for commands to work in a more sane manner
+ Added "default-group" target to Makefile, so that the default group
can be made easily.

Many thanks to Ted Lemon for debugging this.
and use these timeout in the lpq, lpd and lprm programs.
these stop hung remote printers that accept tcp connections but do
not process jobs from hanging the whole system and letting the sysadmin
have a clue about what is going on with this rogue printer.
- add a -r flag to lpd to allow `of' filters for remote jobs.
i know there are ways around this, but i just don't care.
- add a -f flag to lpf to add missing carriage returns.
useful when printing UNIX files to an, eg, LaserWriter that wants CR's
as well as LF's in raw text. stair-stepped text is no fun.
- implement child process accounting: we just have a limit on the number
of children we can have (settable by the sysadmin), and we sleep when
this number is reached. this can reduce malicious not-so-malicious
attacks on the print server by a rogue remote client..
- use setproctitle() where appropriate so the sysadmin has a clue about
what each of the lpd's here are doing.
this was useful to help diagnose a problem (that the above child process
accounting change reduces the lossages of) where a rogue client was
attempting "lpq" operations on one stuck queue in rapid succession,
causing the lpd server to be extremely slow, due to the large number
of lpd processes running.
i have been running these changes in production for about a year.
groupadd/groupmod/groupdel functionality, along with two front-end

Based on the addnerd package, but most of the interface has been
completely rewritten, and suggestions from simonb and mrg have been
incorporated.

While here, convert code to use getopt(3) and do some const poisoning.
Also g/c variables uid and euid, they are no longer needed after

- Minor re-indenting
- Fix printing of @ignore in pkg_info (did this ever work?)
- Fix installing of local wildcard dependencies (unused in main system)
- Fix deleting of packages that depend on wildcard dependencies
(fexist() is not enough there :-)
