* 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
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.
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
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.
* Set umask to 707;
* Disable UMASK, CHMOD, DELE, RMD and MKD commands.
Compile-time options let you change that umask and go back to the
old, insecure way if you like.
