[PATCH OLK-5.10] start_kernel: Add __no_stack_protector function attribute
by Lin Yujun 09 Dec '25

09 Dec '25

From: "ndesaulniers(a)google.com" <ndesaulniers(a)google.com> mainline inclusion from mainline-v6.5-rc1 commit 514ca14ed5444b911de59ed3381dfd195d99fe4b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ID0RFA CVE: CVE-2023-53491 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Back during the discussion of commit a9a3ed1eff36 ("x86: Fix early boot crash on gcc-10, third try") we discussed the need for a function attribute to control the omission of stack protectors on a per-function basis; at the time Clang had support for no_stack_protector but GCC did not. This was fixed in gcc-11. Now that the function attribute is available, let's start using it. Callers of boot_init_stack_canary need to use this function attribute unless they're compiled with -fno-stack-protector, otherwise the canary stored in the stack slot of the caller will differ upon the call to boot_init_stack_canary. This will lead to a call to __stack_chk_fail() then panic.
