Breno Leitao 5d646a7632 crypto: sha256 - fix crash at kexec ... Loading a large (~2.1G) files with kexec crashes the host with when running: # kexec --load kernel --initrd initrd_with_2G_or_more UBSAN: signed-integer-overflow in ./include/crypto/sha256_base.h:64:19 34152083 * 64 cannot be represented in type 'int' ... BUG: unable to handle page fault for address: ff9fffff83b624c0 sha256_update (lib/crypto/sha256.c:137) crypto_sha256_update (crypto/sha256_generic.c:40) kexec_calculate_store_digests (kernel/kexec_file.c:769) __se_sys_kexec_file_load (kernel/kexec_file.c:397 kernel/kexec_file.c:332) ... (Line numbers based on commit da274362a7 ("Linux 6.12.49") This started happening after commit f4da7afe07 ("kexec_file: increase maximum file size to 4G") that landed in v6.0, which increased the file size for kexec. This is not happening upstream (v6.16+), given that `block` type was upgraded from "int" to "size_t" in commit 74a43a2cf5 ("crypto: lib/sha256 - Move partial block handling out") Upgrade the block type similar to the commit above, avoiding hitting the overflow. This patch is only suitable for the stable tree, and before 6.16, which got commit 74a43a2cf5 ("crypto: lib/sha256 - Move partial block handling out"). This is not required before f4da7afe07 ("kexec_file: increase maximum file size to 4G"). In other words, this fix is required between versions v6.0 and v6.16.
