R. Silva # Date: Thu Nov 30 14:29:34 2023 -0600 # # init: Kconfig: Disable -Wstringop-overflow for GCC-11 # # -Wstringop-overflow is buggy in GCC-11. Therefore, we should disable # this option specifically for that compiler version. To achieve this, # we introduce a new configuration option: GCC11_NO_STRINGOP_OVERFLOW. # # The compiler option related to string operation overflow is now managed # under configuration CC_STRINGOP_OVERFLOW. This option is enabled by # default for all other versions of GCC that support it. # # Link: https://lore.kernel.org/lkml/b3c99290-40bc-426f-b3d2-1aa903f95c4e@embeddedor.com/ # Link: https://lore.kernel.org/lkml/20231128091351.2bfb38dd@canb.auug.org.au/ # Reviewed-by: Kees Cook # Link: https://lore.kernel.org/linux-hardening/ZWj1+jkweEDWbmAR@work/ # Signed-off-by: Gustavo A.
