have it check to see that it doesn't contain any '/' characters. This
prevents possible silliness like ypcat "../../../kernel". We already
test the domain name for this in yp_validdomain(), and ypserv itself
tests the map name in yp_open_db(), but it doesn't hurt to be paranoid
and test for it in the generic access routine too. rpc.ypxfrd does not
test the map name for slashes, but it does call yp_access() with the
map name, so this removes a potential vulnerability from there.
Also make the tests for IPPORT_RESERVED a little more selective: make
sure it trips when map == master.passwd.*, prog == YPPROC and proc ==
YPPROC_XFR, and prog == YPXFRD_FREEBSD_PROG and proc == YPXFRD_GETMAP.
Also use IPPORT_RESERVED instead of hard-coded value.
by sysctl and never can be in their documented form (kern.name_max would
have to become fs.filesystemname.name_max, etc.).
Added missing references to user.stream_max and user.tzname_max. These
seem to misnamed. <sys/sysconf.h> says that they correspond to POSIX2
names, but the sysconf names don't have POSIX2 or "posix2" like all the
other POSIX2 names.
and use /dev/console.
I really think the proper test is to determine which device has been configured
to be the console (remember the RB_SERIAL flag?) and use it instead of always
trying to open /dev/ttyv0 first.

ask for matching confirmation. I'm sure there is a clever direct-from-perl
ioctl way of putting the terminal into noecho mode, but I don't feel like
learning perl so I just used system. [yes, I'll put stty on the installation

I could find. This change does the following:
- s/usage()/break;/ in handling the -s switch.
- use err/warn instead of fprintf(stderr, ... strerror()); exit(1);
- implement Hitachi PUMA HitTablet support from the XFree86 code,
whatever the hell that is. :-)
- correctly implement baud rate setting, too much was cut from the
XFree86 code, the critical parts were a sweep over all likely
mouse powerup baud rates to switch it to the reqested rate.
- logitech support was busted (at least on mine, which is autosensing
and runs in either mmseries or logitech mode depending on the handshake
code at startup. Among other things, you talk to it at 1200, then
switch to the target baud later.
Some remaining problems.. samplerate setting is missing, but I've not
found where this is meant to be set yet. I presume this is resolution
setting of some kind.
the real buffer size. Note that the strncpy(domain, ...) doesn't need to
be a strncpy(), since it is copying from itself to itself, but belts
and suspenders don't hurt and this is not time-critical code.

- add ctm_conf.gnats from freefall
- add support for doing both the immediate mailout and the queued mailout.
- use "sendmail -odq -t" rather than "sendamil -t" to make it queue to
the mailqueue rather than immediately begin transmission. This allows
us to take advantage of our ordered dequeueing system without blowing
WC's T1 to hell with a 50 part mailout in parallel.
- bump the max ctm size from 3MB to 10MB.... This is mainly for the fast
list.
we actually look for the *group* and not the user's gid. user daemon
has traditionally been group 31 (guest).
Also clear out the groups vector so that it doesn't inherit the groups
of the invoking user (ever run rwhod by hand before?) Unfortunately, we
can't empty the supplemental groups list because the !&@^#! egid is stored
in there! :-(
of connections, we cannot afford to allow "disappeared" client to cause
us to leave one of the 14 connections open and hanging in a read() forever.
(SO_KEEPALIVE causes probe packets to be sent after a few hours of IDLE
time where no data has been transferred. Sup should NEVER do this, so the
only time it will have an effect is if it looses the remote machine)
files in /var/tmp. Sup needs to send the file size, so that
prevents running gzip in a pipeline (sigh).
It now opens a temporary file, and immediately unlinks it. It sends
gzip's output to the temp file, and when gzip is done, it rewinds the
file and sends it. When the last fd is closed, the file storage is
reclaimed. With luck, this will stop those 15MB
gzip < emacs-19.30.tgz > /var/tmp/tmp.xxxx files from being left behind
and blowing out /var on freefall.

"." means the object directory, so it is just confusing to use it
when nothing is included from the object directory unless the object
directory is also the source directory. It is confusing for "."
not to mean the source directory anyway, so used `-I.'s should be
replaced by `-I${.OBJDIR}'.

I couldn't make any sense of the sentence "Eval variables in this file." so I
left it alone.

this can probably be done more elegantly, and needs more thought.

Ultimately, this rarpd should be replaced with the more recent one

- In yppasswdproc_update_1_svc(), I wasn't paying attention and put
a couple of lines of code _after_ a return() instead of before.
(*blush*)
- The removal of certain temp files didn't always work (this showed
up mostly if you were using /etc/master.passwd as your NIS passwd
template instead of /var/yp/master.passwd). This is because the
whole temp file creation mechanism I was using was tragically
broken (you can't rename across filesystems).
This problem I found myself:
- If you have a very large password database (30,000 or more entries),
there can be a delay of several seconds while pw_copy() copies the
ASCII template file and subsitutes in the modified/new entry. During
this time, the clnt_udp() code in the RPC library may get impatient
and retry its request. This will get queued at the server and be
treated as a second request. By then the password change will have
been completed and the second request will fail (the old password is
no longer valid). To attempt to fix this, we save the IP address and
port of each request and ignore any subsequent requests from the
same IP and same port that arrive within five minutes of each other.
Some things may still display text on the 24th line, but that's because
they've always been screens designed to fit into a minimal real-estate
and have hardwired assumptions about the dimensions. They'll be a little
harder to make dynamic.
