Hello I have a question about the behavior of mmap() in the kernel built without VM_STACK option. The platform is FreeBSD3.3.
When the area allocated by mmap() overlaps the area between vm_maxsaddr and USRSTACK, accessing the overlapped area causes Segmentation Fault, although mmap() is returned successfully. Is this a bug or the intended behavior? Looking through the source code, what happens seems: When grow() is called by the page fault handler trap_pfault(), grow() failes to grow a user stack area because virtual address space has already been taken by mmap(). ----- Kenji Kaneshige [EMAIL PROTECTED] To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
