This is the standard BSD license with clause 3 removed and clause 4
suitably renumbered.

o Because of export controls, TELNET ENCRYPT option is not supported outside
of the United States and Canada.
o Because of export controls, data encryption
is not supported outside of the United States and Canada.

and actually telnet encryption is used outside of US and Canada now.

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.

o Fixed `nfrontp' calculations in output_data(). If `remaining' is
initially zero, it was possible for `nfrontp' to be decremented.

o Replaced leaking writenet() with output_datalen():

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
: 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.

Also update the crypto telnet's man page to reflect other options
ported from the non-crypto version.

references global variables from telnetd, but is also linked into
telnet as well. I was tempted to back out the last sra.c change
as it is 100% bogus and should be taken out and shot, but for now
this bandaid should get world working again. :-(

now the default, so ignore the arguments that turn it on. Add a new -y
argument to turn off encryption in case someone wants to do that. Sync
these changes with the man page (including removing the now obsolete
statement about availability only in the US and Canada).

This allows people to break out of SRA authentication if they wish to.
