6c98f40194 Never emit a message to stderr: use syslog instead.
When in inetd mode, this prevents bogus messages from
appearing on the control channel.  When running as a
daemon, we shouldn't write to the terminal we used to
have at all.

e897216f45 Don't log the chroot dir on every command since it's constant for a session.
Log it once at the beginning of the session instead.  OTOH, log wd each
time for the sake of better auditing and consistent log format.

6b2dee6ba1 Log pathname arguments to ftp commands as the user specified them;
add the working directory pathname to the log message if any of
such arguments isn't absolute.  This has advantage over the old
way of logging that an admin can see what users are actually trying
to do, and where.  The old code was also not too robust when it
came to a chrooted session and an absolute pathname.

6e4b0a55f7 Using off_t to pass a block size is obvious overkill.
The size_t type is better suited for that, particularly because
the "blksize" argument is to be passed to malloc() and read().
On 64-bit archs it's more to a style issue, but the good style
of coding in C is also important.

545ea86459 OpenPAM allows passing a NULL "pamh" to pam_strerror() to indicate
that the creation of a PAM context has failed.

N.B. This does not apply to pam_strerror() in RELENG_4, it
will mishandle a NULL "pamh".

c999732b45 Log the actual number of bytes sent on the wire to /var/log/ftpd
instead of the disk size of the file sent.   Since the log file
is intended to provide data for anonymous ftp traffic accounting,
the disk size of the file isn't really informative in this case.

40e677651c o Merge rev. 1.5 libexec/ftpd/ftpd.c from DragonflyBSD:
Do not unconditionally fork() after accept().  accept() can
  return -1 due to an interrupted system call (i.e. SIGCHLD).
  If we fork in that case ftpd can get into an
  accept()/SIGCHLD/fork/[fail]/repeat loop.

6c124a8422 Open a socket for a data transfer in active mode using euid
of the current user, not root.  This will allow neat things
like matching anonymous FTP data traffic with a single ipfw(8)
rule:
	ipfw add ... tcp from any to any uid ftp

Note that the control connection socket still belongs to the
user ftpd(8) was started from, usually root.
