The purgatory code now uses the shared lib/crypto/sha256.c sha256 implementation. This needs memzero_explicit, implement this. Reported-by: Arvind Sankar <nivedita@xxxxxxxxxxxx> Fixes: 906a4bb97f5d ("crypto: sha256 - Use get/put_unaligned_be32 to get input, memzero_explicit") Signed-off-by: Hans de Goede <hdegoede@xxxxxxxxxx> --- Changes in v2: - Add barrier_data() call after the memset, making the function really explicit. Using barrier_data() works fine in the purgatory (build) environment. --- arch/x86/boot/compressed/string.c | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/arch/x86/boot/compressed/string.c b/arch/x86/boot/compressed/string.c index 81fc1eaa3229..654a7164a702 100644 --- a/arch/x86/boot/compressed/string.c +++ b/arch/x86/boot/compressed/string.c @@ -50,6 +50,12 @@ void *memset(void *s, int c, size_t n) return s; } +void memzero_explicit(void *s, size_t count) +{ + memset(s, 0, count); + barrier_data(s); +} + void *memmove(void *dest, const void *src, size_t n) { unsigned char *d = dest; -- 2.23.0
