The patch as it appeared in broken-out/ is attached. -- wli From: Hirokazu Takata <takata@linux-m32r.org> Hello, Here is a patchset to fix a bug of m32r kernel 2.6.9 that a code on a noexec page can be executed incorrectly. For good security, stack region should be non-executable. This fix is also needed to achieve non-executable stack. Please apply this to 2.6.10 kernel if possible. Thank you.

[PATCH 2.6.10-rc3-mm1] m32r: Don't encode ACE_INSTRUCTION in address (2/3) - To be more comprehensive, keep ACE_INSTRUCTION (access exception on instruction execution) information in thread_info->flags, instead of encoding it into address parameter. [PATCH 2.6.10-rc3-mm1] m32r: Clean up arch/m32r/mm/fault.c (3/3) - Fix a typo: ACE_USEMODE --> ACE_USERMODE. - Update copyright statement, and so on. -- Hirokazu Takata <takata@linux-m32r.org> Linux/M32R Project: http://www.linux-m32r.org/ Signed-off-by: Andrew Morton <akpm@osdl.org> --- _ | ||||||||||||
