e8c6388223 Get rid of __FBSDID macros, which aren't defined in GNO (and thus prevent compilation). 2015-05-30 22:26:48 -05:00

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)

052bf438de Add baud rate support to telnet(1)
This implements part of RFC-2217

It's based off a patch originally written by Sujal Patel at Isilon, and
contributions from other Isilon employees.

0fddcbcf1c telnet: Fix infinite loop if local output generates SIGPIPE.
Instead of catching SIGPIPE and jumping out of the signal handler with
longjmp, ignore it and handle write errors to the local output by exiting
from there. I have changed the error message to mention the local output
instead of NetBSD's wrong "Connection closed by foreign host". Write errors
to the network were already handled by exiting immediately and this now
applies to EPIPE too.

The code assumed that SIGPIPE could only be generated by the network
connection; if it was generated by the local output, it would longjmp out of
the signal handler and write an error message which caused another SIGPIPE.

e1492a80cd Correct a pair of buffer overflows in the telnet(1) command:
(CAN-2005-0468) A heap buffer overflow in env_opt_add() and related
 functions.

 (CAN-2005-0469) A global uninitialized data section buffer overflow in
 slc_add_reply() and related functions.

As a result of these vulnerabilities, it may be possible for a malicious
telnet server or active network attacker to cause telnet(1) to execute
arbitrary code with the privileges of the user running it.

4369ac2a7f Fix up external variables named "debug" that have a horrible habit
of conflicting with other, similarly named functions in static
libraries. This is done mostly by renaming the var if it is shared
amongst modules, or making it static otherwise.

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.

8e7393fb93 Hack to work around braindeath in libtelnet:sra.c. The sra.o file
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. :-(
