jhb 2007-07-12 18:01:31 UTC FreeBSD src repository Modified files: sys/amd64/linux32 linux32_sysvec.c sys/compat/ia32 ia32_sysvec.c sys/kern kern_exec.c kern_resource.c sys/sys sysent.h Log: Fix a couple of issues with the stack limit for 32-bit processes on 64-bit kernels exposed by the recent fixes to resource limits for 32-bit processes on 64-bit kernels: - Let ABIs expose their maximum stack size via a new pointer in sysentvec and use that in preference to maxssiz during exec() rather than always using maxssiz for all processses. - Apply the ABI's limit fixup to the previous stack size when adjusting RLIMIT_STACK to determine if the existing mapping for the stack needs to be grown or shrunk (as well as how much it should be grown or shrunk).
