Stephen Heumann e8c6388223 Get rid of __FBSDID macros, which aren't defined in GNO (and thus prevent compilation). 2015-05-30 22:26:48 -05:00
Stephen Heumann 327170235b Changes to make telnet & telnetd compile on OS X, and begin adapting them to GNO:
*New makefile
*Refer to local versions of telnet-related headers, rather than system ones
*Use termcap instead of termios
*Change hostname lookup in telnetd back to older code (which assumes IPv4, but that's all GNO supports anyway)

kevlo 6b099757e8 Make sure that each va_start has one and only one matching va_end,
especially in error cases.

jhb d76e719277 Don't attempt authentication at all if it has been disabled via '-a off'.
This works around a bug in HP-UX's telnet client and also gives a much
saner user experience when using FreeBSD's telnet client.

markm 820d180830 Very large style makeover.
1) ANSIfy.
2) Clean up ifdefs so that
   a) ones that never/always apply are appropriately either
      fully removed, or just the #if junk is removed.
   b) change #if defined(FOO) for appropiate values of FOO.
      (currently AUTHENTICATION and ENCRYPTION)
3) WARNS=2 fixing
4) GC other unused stuff

This code can now be unifdef(1)ed to make non-crypto telnet.

markm 0fd2377dcc Code merge and diff reduce with "base" telnet. This is the "later"
telnet, so it was treated as the reference code, except where later
commits were made to "base" telnet.

kris 9de6e7ba10 output_data(), output_datalen() and netflush() didn't actually guarantee
to do what they are supposed to: under some circumstances output data would
be truncated, or the buffer would not actually be flushed (possibly leading
to overflows when the caller assumes the operation succeeded).  Change the
semantics so that these functions ensure they complete the operation before
returning.

Comment out diagnostic code enabled by '-D reports' which causes an
infinite recursion and an eventual crash.

Patch developed with assistance from ru and assar.

ru 2c684cfa07 More potential buffer overflow fixes.
o Fixed `nfrontp' calculations in output_data().  If `remaining' is
  initially zero, it was possible for `nfrontp' to be decremented.

Noticed by:	dillon

o Replaced leaking writenet() with output_datalen():

:  * writenet
:  *
:  * Just a handy little function to write a bit of raw data to the net.
:  * It will force a transmit of the buffer if necessary
:  *
:  * arguments
:  *    ptr - A pointer to a character string to write
:  *    len - How many bytes to write
:  */
: 	void
: writenet(ptr, len)
: 	register unsigned char *ptr;
: 	register int len;
: {
: 	/* flush buffer if no room for new data) */
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
: 	if ((&netobuf[BUFSIZ] - nfrontp) < len) {
: 		/* if this fails, don't worry, buffer is a little big */
                   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
: 		netflush();
: 	}
:
: 	memmove(nfrontp, ptr, len);
: 	nfrontp += len;
:
: }  /* end of writenet */

What an irony!  :-)

o Optimized output_datalen() a bit.
