Add mimmutable(2) system call which locks the permissions (PROT_*) of memory mappings so they cannot be changed by a later mmap(), mprotect(), or munmap(), which will error with EPERM instead. ok kettenis

Hold a read lock on the map while copying out data during a sysctl(2) call to prevent another thread from unmapping the memory and triggering an assertion or even corrupting random physical memory pages. This fix is similar to the change in uvm_glue.c rev. 1.74. However in this case we need to be careful since some sysctl(2) calls look at the map of the current process. In those cases we must not attempt to lock the map again. ok mpi@ Should fix: Reported-by: syzbot+be89fe83d6c004fcb412@syzkaller.appspotmail.com

First step towards making uiomove() take a size_t size argument: - rename uiomove() to uiomovei() and update all its users. - introduce uiomove(), which is similar to uiomovei() but with a size_t. - rewrite uiomovei() as an uiomove() wrapper. ok kettenis@

New vmmap implementation. no oks (it is really a pain to review properly) extensively tested, I'm confident it'll be stable 'now is the time' from several icb inhabitants Diff provides: - ability to specify different allocators for different regions/maps - a simpler implementation of the current allocator - currently in compatibility mode: it will generate similar addresses as the old allocator

Reimplement uvm/uvm_map. vmmap is designed to perform address space randomized allocations, without letting fragmentation of the address space go through the roof. Some highlights: - kernel address space randomization - proper implementation of guardpages - roughly 10% system time reduction during kernel build Tested by alot of people on tech@ and developers. Theo's machines are still happy.

Add an extra flags argument to uvm_io(), to specify whether we want to fix the protection of the memory mapping we're doing I/O on, or if we want to leave them as they are. This should only be necessary for breakpoint insertion in code, so we'll only use it for ptrace requests. Initially from art@ after discussion with kettenis@ millert@ and I, tested by many.

UBC was a disaster. It worked very good when it worked, but on some machines or some configurations or in some phase of the moon (we actually don't know when or why) files disappeared. Since we've not been able to track down the problem in two weeks intense debugging and we need -current to be stable, back out everything to a state it had before UBC. We apologise for the inconvenience.
