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.
[Discussed with lukem some time ago.]
* 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.
without search permission. This confused some ftp clients.
We fix this problem by maitaining a cached path when getcwd() does not work.
The symbolic links and ../ are resolved in the cached path, and it is finnally
checked for accuracy by comparing ./ and the cached path with stat (device
and inode comparison). If the comparison fails, pwd fails as it did before,
and if the comparison succeeds, the cached path is displayed.
If paths are too long, we should just compare ./ with a truncated path and
fail, thus making pwd displaying an error as it did before.
- use LLT (aka 'long long type') for all numeric class parameters
- improve description of various ftpd.conf(5) options
- statcmd(): print out: mmapsize readsize writesize sendbufsize sendlowat
