infrastructure and using that infrastructure in programs.
* MKHESIOD, MKKERBEROS, MKSKEY, and MKYP control building
of the infratsructure (libraries, support programs, etc.)
* USE_HESIOD, USE_KERBEROS, USE_SKEY, and USE_YP control
building of support for using the corresponding API
in various libraries/programs that can use it.
As discussed on tech-toolchain.
- mlst shouldn't return cdir or pdir for type, only dir
- mlst should always provide a full path name
- mlsd should provide a full path name for the cdir entry. (providing a
full path name for the pdir entry is optional, and i punted on that).
and with a non-NULL file pointer. active transfers now work correctly again,
passive transfers work, and the data stream is only closed after a PASV or
EPSV if a successful connection was initiated with dataconn().
descriptor was set by dataconn(). this fixes a problem for clients (such
as lynx and netscape) that only sent PASV/EPSV after a transfer (RETR, LIST,
STOR) started and returned 150. certain command sequences could return 550
(etc) before setting up the dataconn(), and would run into this bug. netbsd's
ftp didn't hit this bug because it always sends PASV/EPSV before a new
transfer command.
- 'denyquick'; deny a connection so tagged by ftpusers(5) after the USER
command instead of the PASS command. whilst this might provide some
info leakage of accounts names if you have some `real' or `chroot'
users enabled and not others, it does prevent accidental entering of
such passwords if you have all such users denied. This option is
strongly recommended on anonymous-only servers.
Functionality requested by Rob Windsor in [bin/12602]
- 'private'; don't display class related information in the output of STAT.
For paranoid admins.
Make sure that each va_start has one and only one matching va_end,
especially in error cases.
If the va_list is used multiple times, do multiple va_starts/va_ends.
If a function gets va_list as argument, don't let it use va_end (since
it's the callers responsibility).
Improved by comments from enami and christos -- thanks!
Heimdal/krb4/KAME changes already fed back, rest to follow.
Inspired by, but not not based on, OpenBSD.
- totally clear a glob buffer before use, because FreeBSD depends on
some of the other fields being cleared (other than just gl_offs)
- in strend(), ensure that the source string isn't too large
- remove unnecessarily complicated sizing of proctitle, since snprintf()
will truncate it anyway
define HAVE_SETPROCTITLE and HAVE_SOCKADDR_SA_LEN, because certain
operating systems from a vendor which claims to be the biggest unix
vendor as of two months ago #define BSD4_4 and THEN REMOVE BITS OF THE
4.4BSD API!
anyway, this won't affect other systems which use lukemftpd (e.g,
other 4.4BSD derived systems), because autoconf will set HAVE_SETPROCTITLE
as appropriate. the point of this little code fragment is to remove the
need to have -DHAVE_SETPROCTITLE ... in our libexec/ftpd/Makefile

This involved changing the yacc syntax to be line-oriented, rather than
having it run against the entire input at once, and adding a flag to
struct tab, to indicate if or not it's acceptable for a command to occur
OOB.
