kib feb999713b When protection of wired read-only mapping is changed to read-write, ... install new shadow object behind the map entry and copy the pages from the underlying objects to it. This makes the mprotect(2) call to actually perform the requested operation instead of silently do nothing and return success, that causes SIGSEGV on later write access to the mapping. Reuse vm_fault_copy_entry() to do the copying, modifying it to behave correctly when src_entry == dst_entry. Reviewed by: alc MFC after: 3 weeks		2009-10-27 10:15:58 +00:00
