- new ftpd.conf directives: maxfilesize set the maximum size of uploaded files sanenames if set, only permit uploaded filenames that contain characters from the set "-+,._A-Za-z0-9" and that don't start with `.' - new/changed command line options: -e emailaddr define email address for %E (see below) -P dataport use dataport as the dataport (instead of ctrlport-1) -q use pid files to count users [default] -Q don't use pid files to count users -u write entries to utmp -U don't write entries to utmp [default] -w write entries to wtmp [default] -W don't write entries to wtmp NOTE: -U used to mean `write utmp entries'. Its meaning has changed so that it's orthogonal with -q/-Q and -w/-W. This isn't considered a major problem, because using -U isn't going to enable something you don't want, but will disable something you did want (which is safer). - new display file escape sequences: %E email address %s literal `s' if the previous %M or %N wasn't ``1''. %S literal `S' if the previous %M or %N wasn't ``1''. - expand the description of building ~ftp/incoming to cover the appropriate ftpd.conf(5) directives (which are defaults, but it pays to explicitly explain them) - replace strsuftoi() with strsuftoll(), which returns a long long if supported, otherwise a long - rework the way that check_modify and check_upload are done in the yacc parser; they're merged into a common check_write() function which is called explicitly - merge all ftpclass `flag variables' into a single bitfield-based flag element - move various common bits of parse_conf() into a couple of macros - clean up some comments

various fixes suggested by Robert Elz: * implement closedataconn() and use appropriately (including in mlsd()) * only put leading space in front of MLST output (not MLSD output) * MLSD: only output pdir and cdir entries when the type fact is requested. * change error code for giving MLSD a non-directory from 550 to 501 * remove MLSx Type fact support for UNIX.* for now; it's not standardised yet. * do a check_login when MLSD and MLST are given no args * detect & complain about null facts in OPTS MLST * cache getgroups() at login instead of calling each time in fact_perm() other mods: * implement cprintf(); as per fprintf() but increments total_bytes{,_out} * implement CPUTC(); as per putc() but increments total_bytes{,_out} * implement base64_encode() * fact_unique() display base64 encoding of dev_t and ino_t rather than hex output; should scale if size of those changes * change reply() so that a negative code acts as the initial line in a reply, code == 0 prefixes the line with 4 spaces, and code > 0 works as before. deprecate lreply(code, ) and lreply(0, ) in favour of reply(-code, ) and reply(0, ) respectively. * use cprintf() and CPUTC() appropriately (often instead of printf(), lreply(-2, ) or lreply(-1, ). now we actually account for the data sent by MLST and MLSD. * remove DEBUG support for sending MLSD output to control connection instead of data connection (my ftp client now supports MLSD :-)

major overhaul (just before netbsd 1.5 :-): * implement draft-ietf-ftpext-mlst-10 commands, especially MLST and MLSD. we already supported SIZE and MDTM. add the appropriate FEAT output lines. * migrate a lot of the command code from ftpcmd.y and ftpd.c to cmds.c * make dataconn(), feat(), lookup(), opts() and sizecmd() public * modify struct tab so that it has a `flags' instead of `implemented' element, and remove the `hasopts' element. If flags == 1, the command is implemented. if flags == 2, the command is implemented and takes options * add macros ISDOTDIR(x) (is x ".") and ISDOTDOTDIR(x) (is x "..") * modify lreply() so that lreply(-2, ...) just outputs the given info without a prefix or trailing \r\n. this saves doing b = printf(); total_* += b; * enhance statcmd(). still needs work in the LPRT status stuff. * crank version

* make checkportcmd the default. this breaks third-party proxy ftp but prevents the ftp bounce attack, and we should be secure out of the box, not require users to tweak obscure stuff. * allow the version string reported to clients to be changed with '-V vers'. if vers is empty or `-', don't report a version. * if -r is given, permanently drop root privs * if not a REAL user (i.e, GUEST or CHROOT), and ftpd is running on a port > IPPORT_RESERVED+1, permanently drop root privs * don't bother reverting to root privs to logout of wtmp/utmp; since the file descriptor is already open this isn't necessary. * fix the binding of the port for the PORT/LPRT/EPRT connection to be the ctrl_addr.su_port-1, not hardcoded to `20' (this was broken in the ipv6 merge). if root privs have been dropped, and this would be a port < IPPORT_RESERVED, use a random port instead (which isn't RFC959 compliant but it doesn't appear that many clients care). * prevent login of a new user if privs have been dropped and already logged in as a REAL user (existing check already stops GUEST & CHROOT users). * move the port check stuff into a separate port_check() function, and use for PORT, LPRT, and EPRT checks. inspired by freebsd * minor KNF * minor man page cleanup

various fixes suggested by Robert Elz: * implement closedataconn() and use appropriately (including in mlsd()) * only put leading space in front of MLST output (not MLSD output) * MLSD: only output pdir and cdir entries when the type fact is requested. * change error code for giving MLSD a non-directory from 550 to 501 * remove MLSx Type fact support for UNIX.* for now; it's not standardised yet. * do a check_login when MLSD and MLST are given no args * detect & complain about null facts in OPTS MLST * cache getgroups() at login instead of calling each time in fact_perm() other mods: * implement cprintf(); as per fprintf() but increments total_bytes{,_out} * implement CPUTC(); as per putc() but increments total_bytes{,_out} * implement base64_encode() * fact_unique() display base64 encoding of dev_t and ino_t rather than hex output; should scale if size of those changes * change reply() so that a negative code acts as the initial line in a reply, code == 0 prefixes the line with 4 spaces, and code > 0 works as before. deprecate lreply(code, ) and lreply(0, ) in favour of reply(-code, ) and reply(0, ) respectively. * use cprintf() and CPUTC() appropriately (often instead of printf(), lreply(-2, ) or lreply(-1, ). now we actually account for the data sent by MLST and MLSD. * remove DEBUG support for sending MLSD output to control connection instead of data connection (my ftp client now supports MLSD :-)

* 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

changes to improve portability: * replace union sockunion {} with struct sockinet {}, and modify the code accordingly. this is possibly more portable, as it doesn't rely upon the structure alignment within the union for our own stuff. uses local su_len unless HAVE_SOCKADDR_SA_LEN is defined (set ifdef BSD4_4) (XXX: haven't tested the ipv6 stuff) * always use getaddrinfo() and getnameinfo() instead of maintaining two code paths. (lukemftpd will provide replacements for these on older systems) * use lockf() instead of open(.., O_EXLOCK) to lock the pid file * minor KNF * clean up long long support: create helper #defines and use as appropriate: #define NO_LONG_LONG !
