lukem 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

lukem 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

lukem 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.

itojun b59b162709 ftpd(8): Copy sin6_scope_id from control connection to active data
connection destination, hoping this to help ftpd's behavior with
scoped IPv6 addresses.
I'm not sure if it is the right way, but it is the best way available to us.
LPRT or EPRT command gives no information about which interface (or scope)
to be used for new data connection.

ftp(1): On data connection establishment, warn if scoped address is used.
If peer (ftp daemon) does not handle scoped address, data connection
may not work right.

This seems to be sort of protocol spec hole, not implementation issue.

lukem 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

* 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.

  in every file.

lukem 29ed71b169 new features:

  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.

lukem 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
1998-09-06 10:39:40 +00:00
lukem cf3263f735 * implement NOARGS state, for commands which don't take any arguments.
fixes long standing ftpd bug where two replies would be returned
  to the client if a command was flagged as accepting `ARGS' but the
  parser didn't know how to cope. obvious symptom of this would be
  ftp client is always one error message `behind' the server.
* consistently refer to the RFC as `RFC 959' not `RFC959' or `RFC-959',
  and replace refs to RFC 765 with RFC 959.
* change order of commands in cmdtab[] to: RFC 959, BSD extras, and obsolete.
* whitespace police, deprecate register, replace malloc/strcpy with strdup

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.

lukem 67d65f4970 - ensure 257 reply codes from PWD and MKD are RFC959 compliant:
257 "dirname" some message
  (any "s in dirname should be doubled, per the RFC)
- don't put an extra / in the output of NLST if the last char in the
  directory is a /
- bump the version to 7.01 because of these fixes

lukem 0bba8ce38d * don't depend upon buffer returned by fgetln() to remain. fix mainly
from Tatoku Ogaito <tacha@tera.fukui-med.ac.jp> in [bin/3967]
* fgetln() doesn't \0 terminate its string. look for the \n and replace
  it with \0 (if no \n, ignore the line - it's most likely corrupt)
* more intensive checks on strdup() returns (not a current mem leak,
  but depended upon code elsewhere to cleanup - not good)
* cleanup some syslog error messages
