7543b77a8e * add back support for `-h hostname'; it still may be useful to override
the name advertised to the client, even if ftpd can determine it from
  the ip address that ftpd is bound to. requested by mrg.
* remove -4/-6; they were effectively no-ops since itojun's change in 1.75.
* crank version

6eff1df26e deprecate -h hostname in favour of automatic determination of local hostname.
this is a much cleaner solution for supporting multihomed virtual servers.

8aad99ce9d * move version to separate header file
* use .Dv and .Tn in the man pages as appropriate
* KNF a bit

The following were inspired by similar changes in openbsd, but may
have additional improvements by me:
* add more check_login tests to the parser rules
* nuke a few memory leaks in the parser rules
* clear passwords before free()ing them, for safety
* don't display \r\n in setproctitle() output
* add support for -U, which enables managing /var/run/utmp entries for
  connections. solves [bin/2217] by Jason Downs <downsj@teeny.org>
* fix oob handling for STAT command
* use SIG_ERR instead of -1

e11b8f48c5 * add support for `-h hostname', which defines the hostname to advertise
as (useful for virtual ftp servers in conjunction with inetd.conf(5)'s
  ability to bind to a specific address).
  if this option is used, add `hostname' to the syslog messages.
* improve documentation of command-line options
* don't allow class names of `all' or `none' in ftpusers

21d03121d3 * change format of /etc/ftpusers lines from
userglob [allow|deny]
  to
	userglob[@host] [allow|deny  [classname]]
  where class is a userdefined classname.
  - if host is given it may either be a CIDR address (e.g, `1.2.3.0/24') or a
    hostglob (e.g, `*.foo.com'), and the remote host is matched against that.
  - if classname is given, use that to match entries in ftpd.conf (defaults
    to `guest' for `anonymous'/`ftp' logins, `chroot' for users found in
    /etc/ftpchroot, and `real' for everyone else.

* implement new /etc/ftpd.conf directives:
    classtype classname type	set type of classname to GUEST, CHROOT, or REAL
    motd classname file		file to use instead of /etc/motd
    rateget classname rate	set rateget throttle to rate
    rateput classname rate	set rateput throttle to rate
    upload classname		allow/deny uploads (STOU, STOR, APPE). if
				denied, also acts as `modify deny'.

* implement new `SITE' commands:
    RATEGET	as per /etc/ftpd.conf rateget, but cannot exceed that
    RATEPUT	as per /etc/ftpd.conf rateput, but cannot exceed that

* implement format_file(), which outputs a file to the user, parsing %
  escapes. use to print /etc/ftpwelcome, /etc/motd, and the `display' file.

* implement strsuftoi() (from ftp(1)), which parses a number and
  optional suffix (for use with rateget, etc)

* don't bother seteuid(0) ; bind(...) ; seteuid(pw->pw_uid), since
  we don't need reserved ports (at wasn't getting them anyway).

* update & reorder copyrights

* use strlcpy() as appropriate

397e2cfc53 * change ftpd_popen() to take char *argv[] instead of char *cmd.
the string tokenisation must be performed by the caller (which is
  generally easy because it's almost always a static command).
* change do_conversion() to return a char *argv[] instead of char *cmd.
  tokenisation of the command is done internally.
* change retrieve() to take char *argv[] instead of char *cmd.
  (to take advantage of the above changes).  fixes [bin/8173]
* use fparseln() instead of fgetln()
* store conversions in listed order (rather than reverse order)
* use stringlists instead of handrolling code to manage an argv.

25cf35a4f3 features/fixes:
* implement xferstats. full stats are displayed for `STAT', and a
  summary is displayed upon exit (and syslogged).  inspired by wu-ftpd.
* wrap data xfers in {send,receive}_data with alarm() timeouts. this
  should remove the majority of the `hanging ftpd' problems that
  people were still seeing.  inspired by wu-ftpd.
* link with ../../bin/ls, so that bin/ls is not required under a
  chroot()ed area for `LIST' to work.  based on [bin/4497] from
  "Soren S.  Jorvang" <soren@t.dk>
* migrate code from util.c into ftpd.c, so that it doesn't conflict
  with ls' util.c.
* remove man page comment about ~ftp/bin/ls being necessary.
* bump version to 7.2.0.
* syslog xfer time with xfer stats.
* if appropriate, syslog error message with command.

internal code stuff:
* change arguments of various functions from `char *' to `const char *'.
* define PLURAL(x) macro, which returns `' if x == 1, `s' otherwise.
  use macro appropriately
* lreply(): a code of -1 means ``send line as is''. a code of 0
  means ``send line with 4 space prefix''. don't print a space after
  the `-' for any other code.
* logcmd(): add `const struct timeval *elapsed' and `const char *error'
  for more flexible error reporting

c984c19121 * replace LOG(CMD|BYTES) macros with logcmd(), which is a cleaner
solution with less code replication. use realpath() in logcmd() so
  that all logged filenames are sane.
* support `REST STREAM' in `FEAT' reply (from draft-ietf-ftpext-mlst-05)
* in 'HELP', suffix unimplemented commands with `-' instead of `*'; the
  former is easier to differentiate from `+'.
* deprecate curdir() now that logcmd() doesn't use it.
* ensure all filename buffers are at least MAXPATHLEN+1 in size.
* move jmp_buf errcatch out of extern.h, removing need to #include <setjmp.h>
  in every file.

29ed71b169 new features:
* implement FEAT and OPTS from RFC2389. FEAT returns SIZE and MDTM.
  OPTS only works on NOOP (as a test).
* extend format of /etc/ftpchroot similar to /etc/ftpusers; each entry
  can take an optional trailing `yes' or `no' which indicates if
  chroot should be done (defaults to `yes').
  based on patches from Ty Sarna <tsarna@endicor.com> in [bin/4769]

cleanups/bugs:
* reorder and reformat entries in yacc parser to match cmdtab[].
  add a blank line between each rule.
* add short hasopts and char *options to struct tab, to support OPTS.
* deprecate upper(); use strcasecmp() instead of strcmp()
* remove unnecessary for (;;) { } in yylex();
* replace copy() and sgetsave() with xstrdup()
* fix a couple of `hasyyerrored = 1' that were accidently removed.

0e5bdd5185 * complete fix for `multiple replies returned for single parse error'
problem; move `hasyyerrored' state flag out of yylex() so that
  check_{login,modify} can also set it.
* check result of check_login for PORT command
* set initial timeout before the "setjmp(); for(;;) yyparse()",
  otherwise an invalid command after login incorrectly sets the timeout
  to 5 minutes (rather than what was set in ftpd.conf)
* replace (char *)0 with NULL
* move yyerror() from ftpd.c to ftpcmd.y
* remove need for -Dunix, by using the version string from ftpd.c
  (instead of `BSD-199506')
* move all extern-ed vars into extern.h

9c9d43e6b5 support displaying the stderr output from a LIST or a conversion to
the user at the end of a transfer.
this generates a file in /tmp, so anonymous requires a
writable ~ftp/tmp, which you may not want to do (because it may
allow people to unwanted upload files).

XXX:	a better method of storing the stderr output would be nice, but
	is a lot more effort to implement. this feature can at least be
	used temporarily whilst debugging why an ftp conversion doesn't
	work.
