lukem b918fc0803 Forbid filenames returned from mget that aren't in (or below) the
current directory.
The previous behaviour (of trusting the remote server's response when
retrieving the list of files to mget with prompting disabled) has been
in ftp ~forever, and has been a "known issue" for a long time.
Recently an advisory was published by D.J. Bernstein on behalf of
Yosef Klein warning of the problems with the previous behaviour, so
to alleviate concern I've fixed this with a sledgehammer.

Remember the local cwd after any operation which may change it.
Use "remotecwd" instead of "remotepwd".

lukem 1aa9c35970 If an ftp auto-fetch transfer is interrupted by SIGINT (usually ^C),
exit with 130 instead of 1 (or rarely, 0).
This allows an ftp auto-fetch in a shell loop to correctly terminate the loop.
Should fix PR [pkg/26351], and possibly others.

lukem f3c773016a If connect(2) in xconnect() fails with EINTR, call select(2) on the socket
until it's writable or it fails with something other than EINTR.
This matches the behaviour in SUSv3, and prevents the problem when
pressing ^T (SIGINFO, which is marked as restartable) during connection
setup would cause ftp to fail with EADDRINUSE or EALREADY when the
second connect(2) was attempted on the same socket.
Problem found and solution provided by Maxime Henrion <mux@freebsd.org>.

lukem 90bb61be44 * Work around broken ftp servers (notably ProFTPd) that can't even follow
RFC 2389, and skip any amount of whitespace before a FEATure response.
  The RFC says 'single space' yet ProFTPd puts two.
* Improve formatting of features[] debug dump.

jhawk 401927b1d5 Abstract out progress bar support into progressbar.[ch], for inclusion
in external programs (conditionalized on -DSTANDALONE_PROGRESS).

The following moved from util.c to progressbar.c:
  alarmtimer(), progressmeter(), psummary(), ptransfer(),
  xsignal(), xsignal_restart()

The following moved from extern.h and ftp_var.h to progressbar.h:
  STALLTIME, verbose, fromatty, progress, quit_time, ttywidth

lukem e3cdb47e47 * implement parseport(), which takes a string and attempts to convert
it to a numeric port number
* use parseport() in parse_url() and hookup()
* don't try and lookup the port number using getaddrinfo(), as it's too hard
  to separate a failed host name lookup from a failed service name lookup.
  this was causing lossage on systems that don't have `http' in services(5)
  (such as solaris), but only crept in when we started using getaddrinfo()
  unconditionally.

lukem 29d497f491 - rename NO_QUAD to NO_LONG_LONG, QUAD* -> LL* and add ULL* (unsigned)
equivalents. name change suggested by Klaus Klein <kjk@netbsd.org>

lukem 7816d2586e add support for FEAT and OPTS commands with `features' and `opts'.
(from RFC 2389).

add support for MLST & MLSD (machine parseble listings) with 'mlst', 'mlsd'
and 'pmlsd' (mlsd |$PAGER) commands.  (from draft-ietf-ftpext-mlst-11)

rename remotesyst() to getremoteinfo(), and modify to parse the result from
FEAT (if supported), and take into account the support for the various
extensions such as MDTM, SIZE, REST (STREAM), MLSD, and FEAT/OPTS.
put each feature into one of the following categories:
	- known to work (explicit FEAT)
	- unknown but assume works until explicit failure, when it's
	  then tagged as `known not to work'.
	- known not to work (FEAT succeeded but didn't return anything,
	  or was unknown and then explicit failure)
assign results into features[] matrix.

add support to getreply() so that an optional callback will be called
for each line received from the server except for the first and last.
this is used in FEAT (and MLST) parsing.

modify various commands to check if REST (STREAM), MDTM and SIZE are
explicitly or implicitly supported before using.

fix `syst' when verbose is off.

minor knf (indent goto labels by one space, etc).

simply various command usage handlers by assuming that argv != NULL except
for quit() and disconnect().

lukem 040253276f * migrate the SYST parsing from setpeer() into a separate remotesyst().
call remotesyst() only when login has been successful
  some servers don't let you run SYST until you've successfully logged in.
* in fetch_ftp(), always call setpeer() with autologin disabled, and use
  the following ftp_login() to DTRT.
  this prevents ftp from trying to login a second time if the first autologin
  fails when connecting to a remote site anonymously using autofetch.
* reset unix_proxy and unix_server in cleanuppeer()
* missed a function conversion in the KNF sweep...

lukem 0ac52b3131 roll back to using sscanf() instead of strptime() to parse `yyyymmddhhmmss'
strings, since the latter technically can't parse dates without non

  [noted by Giles Lean <giles@nemeton.com.au>]
* recvrequest(): treat remote=="" as remote==NULL when calling command().
  (to support the above change)

lukem ecb8a0755a - implement `set rprompt'; right side version of `set prompt'. depends on
EL_RPROMPT support i added to editline(3).
- allow $FTPPROMPT and $FTPRPROMPT to override defaults for the relevant
  prompts
- move `%' formatting code from prompt() to expandbuf().
- implement `%.' and `%c', similar to the same % codes in tcsh(1)
  (functionality I added to tcsh nearly 6 years ago), except that `%.'
  always does `...trailing' and `%c' always does `/<x>trailing'.
- unknown `%foo' codes get printed as `%foo'
1999-11-12 02:50:38 +00:00
lukem 14fbd5079e - implement updateremotepwd(); update the global variable `remotepwd'
to contain the remote working directory.
- add `set prompt', a user configurable prompt. (defaults to `ftp> ').
  the following escape characters a la tcsh(1) are supported: %/, %m,
  %M, and %n.
- add global var `username'; used by prompt code
- fix a couple of minor memory leaks
- bump version

lukem 4f2d3550d0 new features:
- add `usage'; displays the usage of a command.
  implemented by calling the c_handler() with argc = 0, argv = "funcname".
- add `passive auto'; does the same as $FTPMODE=auto.
- add `set [option value]'; display all options, or set an option to a value.
- add `unset option'; unset an option.
- add getoptionvalue() to retrieve an option's value, and replace a few
  global variables with calls to this.
- implement cleanuppeer(), which resets various bits of state back to
  `disconnected'. call in disconnect() and lostpeer().
- support completing on `options'.
- improve recovery after a SIGINT may have closed the connection.
  XXX: there's still a couple to fix

other stuff:
- various consistency fixes in the man page.
- ensure that the command usage strings in the code and man page match reality.
- mput/mget: check that the connection still exists before each xfer.
- minor cosmetic changes in confirm().
- set code correctly in sizecmd() and modtime()
- don't need \n in err() strings.
- change lostpeer to take an argument (rather than casting (sig_t)lostpeer
  in signal handlers)
- knf and whitespace police.

lukem da626f2307 a few user interface and cosmetic tweaks:
* confirm(): move from util.c to cmds.c. display mnemonic string in its prompt.
  add support for `q' (terminate current xfer), `?' (show help list)
* in various signal handlers, output a linefeed only if fromatty.
* if fgets(stdin) returned NULL (i.e, EOF), clearerr(stdin) because you don't
  want future fgets to fail. this is not done for the fgets() in the main
  command loop, since ftp will quit at that point.
* unless ftp is invoked with -a, don't retain the anonftp setting between
  hosts (`ftp somehost:' sets anonftp, but you don't want that to `stick'
  if you close that connection and open a new one).

lukem 4309cfaab3 enhancments from Marc Horowitz <marc@mit.edu> to improve connection timeouts:
* implement xsignal_restart(), which only sets the SA_RESTART flag if
  specifically requested
* xsignal() is now a wrapper to xsignal_restart(). INFO, USR1, USR2 and WINCH
  are restartable, ALRM, INT, PIPE and QUIT are not.
* improve getreply()'s timeout code to take advantage of the above.

other changes:
* improve wording of how globbing works for `classic' URLs (host:path).
  suggested by John Refling <johnr@imageworks.com> in relation to PRs
  [bin/8519] and [bin/8520]
* always compile in the `edit' command even if NO_EDITCOMPLETE defined.
  it's just a no-op in the latter case, which is more consistent to
  the users.
* always compile in about: support (i.e, remove NO_ABOUT).
