Latest commit 348c416 Sep 28, 2016 @syzzer syzzer committed with cron2 Make sure options->ciphername and options->authname are always defined
The NCP code does a strcmp(options->ciphername, ...) without first checking
whether options->ciphername is NULL.  This could cause a crash when using
"--cipher none".  This patch fixes that problem by ensuring that
options->ciphername (and options->authname) are never NULL.  Ensuring that
options->ciphername is never null prevents us from having to write null
checks everywhere.
