To: subterfugue-announce@lists.sourceforge.net Subject: [ANNOUNCE] SUBTERFUGUE 0.1.2 From: Mike Coleman <mkc@kc.net> Date: 12 Mar 2000 03:46:17 -0600 SUBTERFUGUE 0.1.2 is available. From NEWS: Version 0.1.2 ("georgia") * Several improvements and new tricks (PathSandbox, NoMunmap, Paranoia, Umask) from Pavel Machek. * Removed dependency on PTRACE_GETPPID. Added use of PTRACE_O_TRACESYSGOOD; the corresponding kernel patch allows backward compatibility with existing versions of 'strace'. ============================================================================== This is SUBTERFUGUE. See 'NEWS' for info on the latest release. SUBTERFUGUE is a framework for observing and playing with the reality of software; it's a foundation for building tools to do tracing, sandboxing, and many other things. You could think of it as "strace meets expect." Here's a short (real) "screenshot" which hints at one of its possible uses: # sf --trick=SimplePathSandbox:"read=['/'];write=['/dev/tty'];net=1" bash # id uid=0(root) gid=0(root) groups=0(root) # rm -f /etc/passwd write deny (unlink): '/etc/passwd' rm: cannot unlink `/etc/passwd': Permission denied BEWARE: This is an alpha release. It might not hose your system, but who can say? You probably shouldn't even be reading this. Don't run this as root, except on a scratch system. Don't use it to run programs where a loss of state might be disastrous (e.g., fetchmail). Consider yourself warned.
