From: LEROY Christophe <christophe.leroy@xxxxxx> commit 56136631573baa537a15e0012055ffe8cfec1a33 upstream. Today, md5sum fails with error -ENOKEY because a setkey function is set for non hmac hashing algs, see strace output below: mmap(NULL, 378880, PROT_READ, MAP_SHARED, 6, 0) = 0x77f50000 accept(3, 0, NULL) = 7 vmsplice(5, [{"bin/\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 378880}], 1, SPLICE_F_MORE|SPLICE_F_GIFT) = 262144 splice(4, NULL, 7, NULL, 262144, SPLICE_F_MORE) = -1 ENOKEY (Required key not available) write(2, "Generation of hash for file kcap"..., 50) = 50 munmap(0x77f50000, 378880) = 0 This patch ensures that setkey() function is set only for hmac hashing.
