Compile-time disable SSH protocol 1. You can turn it
 back on using the Makefile.inc knob if you need it to talk to ancient
 devices.

Damien Miller 00797e86b2 check for crypt and DES_crypt in openssl block 
fixes builds on systems that use DES_crypt; based on patch
from Roumen Petrov
 2015-03-04 05:02:45 +11:00
Darren Tucker e50e8c97a9 Add null declaration of AI_NUMERICINFO. 
Some platforms (older FreeBSD and DragonFly versions) do have
getaddrinfo() but do not have AI_NUMERICINFO. so define it to zero
in those cases.

Damien Miller 72ef7c148c support --without-openssl at configure time 
Disables and removes dependency on OpenSSL. Many features don't
work and the set of crypto options is greatly restricted. This
will only work on system with native arc4random or /dev/urandom.

Considered highly experimental for now.

Damien Miller 3d673d103b - (djm) [openbsd-compat/explicit_bzero.c] implement explicit_bzero() 
using memset_s() where possible; improve fallback to indirect bzero
   via a volatile pointer to give it more of a chance to avoid being
   optimised away.
 2014-08-27 06:32:01 +10:00
Damien Miller d244a5816f - (djm) [configure.ac] We now require a working vsnprintf everywhere (not 
just for systems that lack asprintf); check for it always and extend
   test to catch more brokenness. Fixes builds on Solaris <= 9

Damien Miller 6482d90a65 - (djm) [configure.ac openbsd-compat/bsd-cygwin_util.c] 
[openbsd-compat/bsd-cygwin_util.h] On Cygwin, determine privilege
         separation user at runtime, since it may need to be a domain account.
            Patch from Corinna Vinschen.

Damien Miller 18912775cb - (djm) [commit configure.ac defines.h sshpty.c] don't attempt to use 
vhangup on Linux. It doens't work for non-root users, and for them
   it just messes up the tty settings.

Damien Miller f5bbd3b657 - (djm) [configure.ac atomicio.c] Kludge around NetBSD offering 
different symbols for 'read' when various compiler flags are

Damien Miller 2035b2236d - (djm) [configure.ac sandbox-capsicum.c sandbox-rlimit.c] Disable 
RLIMIT_NOFILE pseudo-sandbox on FreeBSD. In some configurations,
    libc will attempt to open additional file descriptors for crypto
    offload and crash if they cannot be opened.

Damien Miller c96d85376d - (djm) [configure.ac] Do not attempt to use capsicum sandbox unless 
sys/capability.h exists and cap_rights_limit is in libc. Fixes
   build on FreeBSD9x which provides the header but not the libc
   support.

Damien Miller f62ecef993 - (djm) [configure.ac] Fix detection of capsicum sandbox on FreeBSD 2014-01-25 12:34:38 +11:00
Darren Tucker 42a0925301 - (dtucker) [configure.ac] NetBSD's (and FreeBSD's) strnvis is gratuitously 
incompatible with OpenBSD's despite post-dating it by more than a decade.
   Declare it as broken, and document FreeBSD's as the same.  ok djm@

Damien Miller 5c2ff5e31f - (djm) [configure.ac aclocal.m4] More tests to detect fallout from 
platform hardening options: include some long long int arithmatic
   to detect missing support functions for -ftrapv in libgcc and
   equivalents, actually test linking when -ftrapv is supplied and
   set either both -pie/-fPIE or neither. feedback and ok dtucker@

 2014-01-22 16:31:18 +11:00
Darren Tucker 096118dc73 - (dtucker) [configure.ac] Make PIE a configure-time option which defaults 
to on platforms where it's known to be reliably detected and off elsewhere.
   Works around platforms such as FreeBSD 9.1 where it does not interop with
   -ftrapv (it seems to work but fails when trying to link ssh).  ok djm@
 2014-01-21 12:48:51 +11:00
Darren Tucker fdce373166 - (dtucker) [configure.ac] On Cygwin the getopt variables (like optargs, 
optind) are defined in getopt.h already.  Unfortunately they are defined as
   "declspec(dllimport)" for historical reasons, because the GNU linker didn't
   allow auto-import on PE/COFF targets way back when.  The problem is the
   dllexport attributes collide with the definitions in the various source
   files in OpenSSH, which obviousy define the variables without
   declspec(dllimport).  The least intrusive way to get rid of these warnings
   is to disable warnings for GCC compiler attributes when building on Cygwin.
   Patch from vinschen at redhat.com.

Darren Tucker fd994379dd - (dtucker) [aclocal.m4 configure.ac] Add some additional compiler/toolchain

   that doesn't work (see https://bugzilla.redhat.com/show_bug.cgi?id=1021897).
