Re: panic truss'ing linux ls
Linux has added, among other things, a new exit system call,
"group_exit". It tells an entire thread group to exit. I don't
believe we really support Linux's thread semantics correctly,
so I've mapped it, for the moment, to sys_exit. This allows
ls and everything else to work without dumping core. I don't know
what the ramifications of NPTL will be on Linux compatibility.
truss will still dump core when run against a linux binary, I haven't
I haven't waited for build world to complete to see if it will fix
itself. Compiling truss in its own directory fails painfully.
Linux seems to be using PAM pretty heavily these days to work around
the cripple root/everyone else security model. Is this something worth
importing for compatibility purposes?
