hi! i'm working on a new concept of i386 memory management and have to change quite a bit of the linux mm. could someone please point out, where the location & size of the USER-MODE stack is set for a new program (i.e. after calling sys_execve...) exactly?
I know that all settings are simply copied from the parent-process when invoking fork and how the stack grows (through page-faults). However, 1.) is mm->start_stack set inside the search_binary_handler / the individual fs-handlers? i see that the aout-, elf-, etc. handlers all set this variable --> is this the only location where it can be set? 2.) when looking at /proc/PID/maps, i see that the stack always ends at different locations (obviously close to TASK_SIZE). thus the sizes seem to vary. where are they set / where are the infos written to the vma's / the PGD? any help would be greatly appreciated!! greets, clemens - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
