Thread-topic: [UNIKRAFT PATCH v4 0/4] 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 Changes since v3: * Added config option for constant value/random source for the canary. * Updated the config * Updated library title * Moved uksp/stackprotector.h to uk/sp.h * Added current stack pointer to the crash message Vlad-Andrei Badoiu (2): Move UK_SWRAND_CTOR_PRIO to uk/swrand.h lib/ukboot: Initialize the canary value at boot Vlad-Andrei BĂDOIU (78692) (2): lib/uksp: Introduce uksp library build: Add option to toggle the stack protection Makefile.uk | 10 ++++-- lib/Config.uk | 4 +++ lib/Makefile.uk | 1 + lib/ukboot/boot.c | 8 +++++ lib/uksp/Config.uk | 51 ++++++++++++++++++++++++++++ lib/uksp/Makefile.uk | 21 ++++++++++++ lib/uksp/exportsyms.uk | 2 ++ lib/uksp/include/uk/sp.h | 58 ++++++++++++++++++++++++++++++++ lib/uksp/ssp.c | 50 +++++++++++++++++++++++++++ lib/ukswrand/include/uk/swrand.h | 2 ++ lib/ukswrand/swrand.c | 2 -- 11 files changed, 205 insertions(+), 4 deletions(-) create mode 100644 lib/uksp/Config.uk create mode 100644 lib/uksp/Makefile.uk create mode 100644 lib/uksp/exportsyms.uk create mode 100644 lib/uksp/include/uk/sp.h create mode 100644 lib/uksp/ssp.c -- 2.20.1 _______________________________________________ Minios-devel mailing list Minios-devel@xxxxxxxxxxxxxxxxxxxx https://lists.xenproject.org/mailman/listinfo/minios-devel
