Use truncate() instead of otruncate() - step on the way to stopping

Add (but don't activate) code for a special VM option to make

downward growing stacks more general. Add (but don't activate) code to use the new stack facility when running threads, (specifically the linux threads support). This allows people to use both linux compiled linuxthreads, and also the native FreeBSD linux-threads port. The code is conditional on VM_STACK. Not using this will produce the old heavily tested system. Submitted by: Richard Seaman

According to the author..

"I've been having a problem running the patches [committed to current] installed with the COMPAT_LINUX_THREADS option along with the VM_STACK patches I did. I'm not sure what the problem is, since it seemed to work before. In any event, the attached patch fixes the problem for me. While I've had no report of problems from anyone else, possibly it would be wise to commit the patch until the problem is found. Also, there was some left-over junk in the linux_misc.c file from some earlier work I did. The attached patch cleans that up too." Submitted by: "Richard Seaman, Jr."

Kill(pid, 0) normally returns 0 on both FreeBSD and Redhat after having

1998-12-21T19:21:36Z

performed all sorts of sanity checks. The FreeBSD linux emulator returns EINVAL in such a case. Allowing signal 0 to be passed to kill will result in compatible behaviour. PR: 9082 Submitted by: Marcel Moolenaar

Submitted by: "Richard Seaman, Jr." Obtained from: linux :-) Code to allow Linux Threads to run under FreeBSD. By default not enabled This code is dependent on the conditional COMPAT_LINUX_THREADS (suggested by Garret) This is not yet a 'real' option but will be within some number of hours.

Removed the cast to a pointer in the definition of PS_STRINGS and

1998-12-16T16:28:58Z

adjusted related casts to match (only in the kernel in this commit). The pointer was only wanted in one place in kern_exec.c. Applications should use the kern.ps_strings sysctl instead of PS_STRINGS, so they shouldn't notice this change.
