|Remove bogus use of useracc() in (clock_)nanosleep. | |There's no point in pre-checking that we can access the user's rmtp |pointer before we do it in copyout(). | |While here, improve style(9) compliance.

When handling a 32-bit sendmsg(2) call, the compat32 subsystem copies the control message to be transmitted (if any) into kernel memory, and adjusts alignment of control message headers. The code which performs this work contained a time-of-check to time-of-use (TOCTOU) vulnerability which allows a malicious userspace program to modify control message headers after they were validated by the kernel.

Fix the wait6(2) on 32bit architectures and for the compat32, by using the right type for the argument in syscalls.master. Also fix the posix_fallocate(2) and posix_fadvise(2) compat32 syscalls on the architectures which require padding of the 64bit argument.

Revert some of the recent changes with misc functions in freebsd compatibility. I have no idea what i was thinking before.

Regen syscall table so we don't try to use them.

Introduce CPU Affinity in MidnightBSD.

The ULE scheduler is now default on i386 and amd64 architectures.

cpuset(1) allows the user to limit a process to a group of CPU cores to run on using new system calls.

32bit versions of the system calls were also added to support 32bit binaries running on amd64 boxes. libc's

symbol map was modified to include the cpuset* system calls to expose them to userland.

This is based on work by Jeff Roberson from FreeBSD 7.1.
