dbe59dc029 1) Use "pathstring" instead of "STRING" consistently.
2) Remove unneeded "if not NULL" props from "pathstring",
   which will never be NULL by the lexer design.

37e3668bf5 Since GLOB_NOCHECK is set in the glob(3) call,
glob(3) will return at least one pathname unless
a system error has occured.  It's not a "not found"

Earlier, a decimal number (e.g., 890) could be passed
for mode, leading to dangerous permissions set:
-1, that is, 07777.

fb79ef5523 Teach REST how to restart a file transfer after 2^31 bytes: now yylex()
returns off_t in yylval.u.o. REST is the only user of yylval.u.o at the
moment.

NB: seems lukemftpd has the same bug.

dc82fedb5a Remove the setjmp/longjmp stuff completely. Use signal
handlers to set flags only (with exception for sigquit(),
which still seems to call some non-reentrant functions on
its way to _exit(2).)  That must eliminate the possibility
of catching SIGSEGV from following non-reentrant paths from
signal handlers.

c86b5450b5 Extend the functionality offered by the -o option into a new option
-O, which limits the impact of the write-only restriction to guest
users.

*) The existing manual page's SYNOPSIS and option listing in the
   DESCRIPTION are already horribly disordered.  No attempt has been
   made to fix this.

28e8743f4b Add a new option, '-o', for "Write-only". Disables the RETR command,
preventing anyone from downloading files.  In conjunction with -A, and some
appropriate file permissions, this lets you create an anonymous FTP drop
box for people to upload files to.

The more obvious "-w" flag is already taken by NetBSD's ftpd.  "-o" was
available as an option letter in all three BSDs.

2f71212769 Previous clobbered a work-in-progress. Here is the merged result:
Limit the "pathname" glob to one item, as that is what all users of it
are expecting, except for LIST.

Always glob, instead of when the first character is a ~.  For example,
if you had directories ~/x1, and ~/x2, then "cwd x[1]" would fail, but
"cwd ~/x[1]" would work since it was globbed due to the ~ character.
Also, "cwd ~/x[12]" used to arbitarily work as it used the first
expansion (ie: x1) without an error.  Make it return '550 ambiguous'
instead of '550 not found' so that the user can see the difference.

For LIST, just use the user supplied string as the popen does the glob.

a463dd29ce Add the "SITE MD5 filename" facility.
This allows you to determine if the file on the other side is the same
as the one you have without transferring the entire file to compare.

Needless to say, if the server end lies to you this check doesn't work,
but on the other hand, if it lies to you about the files checksum,
what can you trust from it ?

d8ac409160 Many places in the code NULL is used in integer context, where
plain 0 should be used.  This happens to work because we #define
NULL to 0, but is stylistically wrong and can cause problems
for people trying to port bits of code to other environments.

3782e8c314 If PARANOID is set, do not allow PORT commands to remote ports less than 1024
or addresses other than the requestor's address.  This violates the FTP
protocol (hmm...as I write this, I'm going to change this to a run-time var.)

Require login before PASV and RNTO commands.

Close unused PASV ports so they don't hang around forever.

Do not allow file overwrites via rename or STOR when anonymous
(suspenders).

Clean up buffer utilization.

My code, but heavily inspired by Hobbit's changes to wu-ftpd as pointed out
by Mike Prettejohn and Kit Knox.
