I hit a compiler error caused by e4160b2e4b02377c67f8ecd05786811598f39acd.
x86/purgatory: Fail the build if purgatory.ro has missing symbols
Having CONFIG_STACKPROTECTOR* & CONFIG_KEXEC_FILE enabled always results in a linking error like this:
LD arch/x86/purgatory/purgatory.chk ld: arch/x86/purgatory/purgatory.ro: in function `verify_sha256_digest': purgatory.c:(.text+0x108): undefined reference to `__stack_chk_fail' ld: arch/x86/purgatory/purgatory.ro: in function `sha256_transform': sha256.c:(.text+0x1c74): undefined reference to `__stack_chk_fail' ld: arch/x86/purgatory/purgatory.ro: in function `__sha256_final': sha256.c:(.text+0x1e65): undefined reference to `__stack_chk_fail' ld: arch/x86/purgatory/purgatory.ro: in function `_kstrtoull': string.c:(.text+0x2107): undefined reference to `__stack_chk_fail'
I didn't look closer at that but from the error, it seems to be, some missing -fstack-protector* vs -fno-stack-protector* checks somewhere.
Best Regards,
