| |
Hi!
This is an updated version of the guard page series:
V1: https://lkml.kernel.org/r/20190331214020.836098943@linutronix.de V2: https://lkml.kernel.org/r/20190405150658.237064784@linutronix.de
Changes vs. V2:
- Fixed the broken stack trace storage in slub
- Adjust the guard page ordering and fix the top macro (Sean)
- Fix an off by one in the debug stack check (Sean)
- Rename ISTACK_ prefix to ESTACK_ (Josh)
- Collected Acked/Reviewed-by tags
The lot is also available from tip:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git WIP.x86/stackguards
310a7f5b0b42 ("x86/irq/64: Remove stack overflow debug code")
Thanks,
tglx
