interface, and statically link them to the programs using them.
These functions, upon reflection and discussion, are too generically
named for a library interface with such specific functionality.
Also the api that they use, whilst ok for private use, isn't good
enough for a libc function.
Additionally there were complications with the build/install-world
process. It depends heavily upon xinstall, which got broken by
the change in api, and caused bootstrap problems and general mayhem.
There is work in progress to address future problems that may be
caused by changes in install-chain tools, and better names for
{g|s}etflags can be derived when some future program requires them.
For now the code has been left in src/lib/libc/gen (it started off
in src/bin/ls).
It's important to provide library functions for manipulating file
flag strings if we ever want this interface to be adopted outside
of the source tree, but now isn't necessarily the right moment
with 4.0-release just around the corner.

When hostname is not set, ftpd core dumps, because there is no
NULL check for freeing name resolving information for its own
hostname.
So the check is added.

o use return 0 at end of main when needed
o use braces to avoid potentially ambiguous else
o don't default to type int (and also remove a useless register

Fix INTERNAL_LS to sense new /etc/localtime after chroot
any case.
It makes no difference for anon account (since chroot already makes it GMT),
but if you do mirror with special non-anon login, in old variant
your mirror will be wholy retransmitted twice in the year due to
time zone changes (/etc/localtime plays bad role here)

NULL to 0, but is stylistically wrong and can cause problems

modules from src/bin/ls, and handling exec(_PATH_LS,..) as a
special case, very useful in an environment where many users
are given chroot access. "~/etc/{s}pwd.db" files are still
needed if uid/gid->user/group translation is desired.
To enable this it must be compiled with the make variable

environment.
- Use MAP_FAILED instead of the constant -1 to indicate
failure (required by POSIX).
- Removed flag arguments of '0' (required by POSIX).
- Fixed code which expected an error return of 0.
- Fixed code which thought any address with the high bit set
was an error.
- Check for failure where no checks were present.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
password: ask for it, but don't tell that S/key password required.
It looks like non-s/key system from outside.
Additionally tell that s/key required when it is so for normal case
It happens if 1) regular passwords not allowed, 2) skey database

Under some rare circumstanes skey_challenge can return empty

Document the new -R (relax paranoia) option.
From NetBSD/Lite2: code and man page cleanups, Kerberos IV hooks

protocol (hmm...as I write this, I'm going to change this to a run-time var.)

Clean up buffer utilization.

by Mike Prettejohn and Kit Knox.
accepting connections on the FTP port and forking children processes to
handling them. This is lower overhead than spawning ftpd from inetd and
can be a significant win on busy FTP servers. Be sure to disable ftpd in
inetd.conf if you decide to use this option.
These changes are based on similar changes I made to wu-ftpd and have
been in use on wcarchive for several months.
- set TCP_NOPUSH to keep from sending short packets at each write(2) boundary
- set SO_SNDBUF to 64k so we have a reasonable amount of buffer space
- for a regular file in binary mode which is not being restarted and is
. smaller than 16 Meg, use mmap(2) and write(2) the whole file in one big
gulp
In the most common circumstances, this should dramatically reduce the
system-call load from ftpd, since the call to write() will not return until
the entire file has been written, rather than writing just a few K at a time
in a loop.
libskey contains references to _crypt and can't resolve it unless
-lcrypt occurs after it in the link command. This only occurs when
linking statically.
(as is printing out a version number at the telnet login banner).
Don't print out /etc/motd when people login, instead if present,
print out /etc/ftpmotd. It looks like 4.4lite2 has done something similar
(perhaps for different reasons) because /etc/motd no longer shows up
on vangogh.
Folks who like the old behavior can create a symbolic link to motd.
