2017-08-22Use a boolean variable to remember the quotation level instead ofAlexander Bluhm
doing string pointer arithmetic. Fixes a clang warning. OK otto@ tom@
2017-07-19A few cleanups. This only needs to operate on systems with SIGWINCH,Theo de Raadt
SIGINFO, and Bxxxx values that equal xxxx. ok tom millert
2017-07-07Remove unnecessary #ifdefs in telnet. No binary change.Frederic Cambus
OK deraadt@, tedu@
2016-05-03telnet should not verify if hostname is a fully qualified domainAdam Wolk
telnet would perform a gethostbyname on close/quit commands when the machine hostname is not a fully qualified domain. This behavior added on 12-March-98 breaks the current pledge that "dns" operations are not needed after establishing a connection leading to a coredump from telnet when quiting or closing an existing connection.

2015-12-23Add rpath to telnet's more restrictive pledge; otherwise if the server requestsStuart Henderson
the client to send the next terminal-type (RFC-1091), the client tries to read terminfo files and is killed by pledge. Noticed when connecting to 4.3 BSD. ok semarie@ tb@

2015-11-13move pledge(2) after setrtable(2), like in nc(1);Ingo Schwarze
OK deraadt@
2015-11-13pledge "stdio rpath wpath getpw inet tty" at startup. After openingTheo de Raadt
the socket and entering the main loop, pledge "stdio tty". For my next trick, I will be adding chacha20-poly1305 support.
2015-11-13Use setrtable() for the entire process, rather than doing it for theTheo de Raadt
socket later. Same idea as in nc(1).
2015-11-13Remove support for the debug command; noone needs setsockopt SO_DEBUGTheo de Raadt
2015-11-13Delete tracefile command. Tracefiles can now only be specified atTheo de Raadt
program startup. Who uses that? Noone... ok millert

2015-10-26Set low-delay traffic class for IPv6 connections as wellJeremie Courreges-Anglas
While here, there is no option to pass a different tos, and no other use of the "tos" variable out of tn(), so move the "tos" variable in tn() and assign it the right value from the start. ok millert@

2015-03-29Revert r1.29 "Don't clear ICRNL when editing mode is off, so that characterStuart Henderson
local echo mode don't echo ^M locally" as this causes problems sending CR to some Cisco equipment reported by Ryan Freeman and Fred Crowson. kettenis@ agrees with reverting to fix the regression; we can consider a better diff afterwards but clearly this is a sensitive area.
2015-03-13remove the first comma from constructs like ", and," and ", or,": you can useJason McIntyre
"and" and "or" to join sentence clauses, and you can use commas, but both hinders reading;

mode don't echo ^M locally analysis and patch from Stanislav Brabec (sbrabec (at) suse.cz)
2015-01-16Replace <sys/param.h> with <limits.h> and other less dirty headers whereTheo de Raadt
possible. Annotate <sys/param.h> lines with their current reasons. Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution. These are the files confirmed through binary verification. ok guenther, millert, doug (helped with the verification protocol)
2014-11-15Reduce instances of `` '' in manuals.Anthony J. Bentley
troff displays these as typographic quotes, but nroff implementations almost always print them literally, which rarely has the intended effect with modern fonts, even in stock xterm. These uses of `` '' can be replaced either with more semantic alternatives or with Dq, which prints typographic quotes in a UTF-8 locale (but will automatically fall back to `` '' in an ASCII locale). improvements and ok schwarze@
