[Scst-devel] [PATCH 2/5] kbuild: remove stack protector flags
|
From: Tony B. <to...@cy...> - 2025-09-02 17:18:07
|
-fstack-protector-strong is controlled by the in-tree
CONFIG_STACKPROTECTOR_STRONG config option. If the flag is set without
the config option, scst fails to build:
ERROR: modpost: "__stack_chk_fail" [scst/src/scst.ko] undefined!
-fstack-clash-protection is disabled in the kernel's Makefile due to an
incompatibility with randomize_kstack_offset.
Fixes: 86d3d4bb1d14 ("kbuild: Enable additional compiler warnings")
Signed-off-by: Tony Battersby <to...@cy...>
