lukem 635a375704 Fixes from (or inspired by) OpenBSD:
* 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.

lukem be437fb5c3 - move password checking into separate valid_passwd() function, to assist
in porting to other systems.
- don't syslog() or setproctitle() "ACCT" lines (as per "PASS")
- replace #ifdef HASSETPROCTITLE with #if HAVE_SETPROCTITLE, and set the
  latter #ifdef BSD4_4
- don't compile in internal `ls' #ifdef NO_INTERNAL_LS. will need Makefile
  support if this is to be used on NetBSD.

lukem 18be3cd981 - Always close(pdata) if it was a valid filedescriptor before setting it to -1.
Problem noted in [bin/9642] by Takahiro Kambe <taca@sky.yamashina.kyoto.jp>,
  (part of which already had been solved by itojun a while ago), and provided
  patch covered most of the fixes needed. (Thanks Takahiro!)
- Consistently indent goto labels by one space.

lukem c8493e9499 * add ftpd.conf directive `portrange class min max', which allows specification
of the port range used by passive connections. based on work in [bin/9158]

* change the way global variables are defined and extern-ed to be more
  consistent.
2000-01-12 22:39:27 +00:00
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
1999-12-12 14:05:54 +00:00
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.

lukem 4b2b2847cc * fix a problem in retrieve() where arguments to commands weren't working
(this was broken in the last commit). problem noticed by simonb@
* don't display the stderr output of the internal ls.
* modify usage of lreply so that generally only one `XXX-' code per
  `block' is displayed; the rest of the lines have four spaces instead.
  i find this easier to read.
* fix a couple places where byte accounting wasn't correct
1999-05-18 08:14:17 +00:00
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

lukem 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.
1998-12-28 04:54:00 +00:00
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

kleink fc5d36f8e4 GLOB_QUOTE is dead; per POSIX, backslash quoting of special characters being
enabled is the default behaviour.
1998-06-19 22:58:04 +00:00
lukem 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.

lukem 31547ec641 * implement /etc/ftpd.conf, which adds support for the following features,
controllable on a per class (which is one of: real, chroot, guest,
  all or none) basis:
    * on-the-fly execution of a command to build the file (a ``conversion''),
      providing support for "get dirname.tar" and the like.
    * displaying the contents of a file when a directory is entered
      for the first time.
    * maximum value for timeout (replaces -T).
    * control usage of CHMOD, DELE, MKD, RMD, UMASK; replacing -DINSECURE_GUEST.
    * notifying the user of the existance of a files matching a glob
      pattern when a directory is entered for the first time.
    * default value for timeout (replaces -t).
    * default umask (replaces -DGUEST_CMASK and -u).
  The conversion, display, and notify functionality was based on code by
  Simon Burge <simonb@telstra.com.au>.
* clean up and re-order parts of the man page into subsections.
* STAT displays the settings defined for the class of the current user.
* bump version from 6.00 to 7.00, because of ftpd.conf.
* deprecate -DGUEST_CMASK and -DINSECURE_GUEST in the Makefile, and
  -t, -T and -u, as ftpd.conf allows finer control of these.
* add "nostderr" argument to ftpd_popen(), because you don't want the
  stderr stream mixing with the stdout stream during a conversion,
  as this can corrupt the stream.

lukem 66783f1f43 * fix "cd ~" so that it works (from Simon Burge <simonb@telstra.com.au>
