This allows for setting the passive socket's SO_RCVBUF. Option works
similarly to the current sendbufsize configuration option.
* Change how recveive_data() works
When reading data from the socket for passive transfers to the server,
receive_data() now works very similar to send_data_with_read(). Reads
from the network are now done using either the filesystem block size or
the configuration option readsize chunks.
* Crank version.h
[Changes discussed with lukem.]
ftpd will listen on the default FTP port for incoming connections and fork
a child for each connection. This is lower overhead than starting ftpd from
inetd(8) and thus might be useful on busy servers to reduce load.
Inspired by FreeBSD.

with MKPIC=no, possibly because the target does not support shared
libraries, these include libraries required to resolve all symbols
which end up referenced from PAM-using applications. The libraries
presently required are -lcrypt, -lrpcsvc and -lutil.
Add use of these variables which are currently set up to use PAM,
so that they compile when MKPIC=no.
Also, in the telnetd case, reorder the order of the libraries, so
that libtelnet.a comes before -ltermcap and -lutil, again to fix
link error when MKPIC=no.
Discussed with thorpej and christos.
This adds a -L to all ls command arguments so that the file or directory
the link references is listed rather than the link itself. This was
inspired by IRIX ftpd's -S option.

* Crank version.h [right Luke? :-)]
that is required to change their password will not be allowed FTP
access. Inspired by similar functionality in other FTP daemons.
(approved by lukem)
* Crank version to 20041119 per lukem's request.
* Fix yacc parser error recovery so that setjmp(3)/longjmp(3) is unnecessary.
* Fix SIGURG handler to set an urgflag that's later tested, rather than
abusing setjmp(3)/longjmp(3).
* Use "volatile sig_atomic_t" as the type of variables modified by sig handlers.
* Use sigaction(3) instead of signal(3) to set the signal handlers.
* Only set the main SIGALRM handler once. If we need to change it,
cache the old handler and restore appropriately...
* Remove a bunch of signal races by improving the signal handlers.
* Fix memory leak with 'ESPV ALL'.
My stuff:
* Clean up the debug message in reply(); use vsnprintf(3) instead of vsyslog(3).
* Rework parsing of OOB commands to _not_ use the yacc parser, since the
latter isn't reentrant and the hacks to work around that are ugly.
We now examine urgflag at appropriate locations and call handleoobcmd()
if it's set. Since the only OOB commands we currently implement are
ABOR and STAT, this isn't an issue. (I also can't find the reference in
RFC2228 where MIC, CONF & ENC are OOB-only commands. Go figure.)
I could clean up the is_oob stuff some more, but the remaining stuff
in ftpcmd.y is harmless and it's unnecessary churn right this moment.

per suggestion in mail from Mike Heffner <mheffner@vt.edu>, who
forwarded patch from Michael Ranner <mranner@inode.at>.
on <security@freebsd.org>, and subsequently in FreeBSD's cvs repository
as libexec/ftpd/ftpd.c rev 1.133:
The FTP daemon was vulnerable to a DoS where an attacker could bind()
up port 20 for an extended period of time and thus lock out all other
users from establishing PORT data connections. Don't hold on to the
bind() while we loop around waiting to see if we can make our
connection.
Bump version to 20030122.
