- Thread-topic: [UNIKRAFT PATCH v3 0/3] lib/uksp: Introduce uksp library
Currently, we provide a basic implementation of stack smashing protection that
has a global value for all threads. The value is randomly initialized during the
boot. Finally, this option might help us detect bugs caused by stack overflows.
Changes since v1:
* We now use a choice based config option for the stack protector level. Since
the last version we added the regulat and strong stack protector options.
Changes since v2:
* Renamed the library to uksp
Vlad-Andrei BĂDOIU (78692) (3):
lib/uksp: Introduce uksp library
build: Add option to toggle the stack protection
lib/ukboot: Initialize the canary value at boot
