Date: Tue, 1 Oct 2013 13:25:01 +0400 From: Solar Designer <solar@...nwall.com> To: john-dev@...ts.openwall.com Subject: rakp format magnum, The CPU rakp format segfaults during self-test for me, at least in an linux-x86-64-avx build without OpenMP. The segfault occurs inside the first one of these free() calls from formats.c: fmt_self_test(): MEM_FREE(salt_alloc); MEM_FREE(binary_alloc); Commenting both of them out results in a self-test failure reported for crypt_all(), which means that it returns other than the expected value. This suggests that crypt_all() itself causes memory corruption (both heap and stack at once? would be weird). I guess you're the one to fix this. Additionally, both rakp and rakp-opencl process the salt for each candidate password individually (unless the OpenCL compiler manages to optimize that, which it might). I think a SHA-1 computation may be moved from crypt_all() into set_salt(). Thanks, Alexander
