Hi, When I was trying run the test code openssl-1.0.2h/test/hmactest.c in FIPS mode, I got SIGSEGV. I did following changes to run it in FIPS mode. a) Added FIPS_mode_set(1); b) Commented out the test 1 ~ test 3 since MD5 is not supported in FIPS mode. c) I renamed hmactest.c to hmactest_changed_for_test4_in_fips.c
OpenSSL version: 1.0.2h
OpenSSL FIPS version: 2.0.12
OS: CentOS 6.7
I compiled it like this:
# gcc -I /usr/local/ssl/include/ -L /usr/local/ssl/lib/ -lcrypto
-Wl,-rpath=/usr/local/ssl/lib/ hmactest_changed_for_test4_in_fips.c
(The e_os.h is at same directory with hmactest.c)
Output from gdb:
(gdb)
192 if (HMAC_Init_ex(&ctx, NULL, 0, NULL, NULL)) {
(gdb)
197 if (HMAC_Update(&ctx, test[4].data, test[4].data_len)) {
(gdb)
Program received signal SIGSEGV, Segmentation fault.
This issue could be reproduced with the attached
hmactest_changed_for_test4_in_fips.c
Thanks,
Ziyan
