#1 0xffff80ffba0eabec in hmac_ctx_cleanup (ctx=0x412ac0) OPENSSL_cleanse () at crypto/x86_64cpuid.s:184 Program received signal SIGINT, Interrupt. Starting program: /export/home/jwalton/openssl/test/hmactest $ LD_LIBRARY_PATH=".:$LD_LIBRARY_PATH" gdb test/hmactest As can be seen, the execution results in a loop between lines 184 and 189. You can run the test under a debugger with the following. $ LD_LIBRARY_PATH=".:$LD_LIBRARY_PATH" test/hmactest Note that $PWD is the root of the OpenSSL distribution, and the libraries are put on path using LD_LIBRARY_PATH. You can manually execute the test with the following. test/buildtest_hmac: ELF 64-bit LSB executable AMD64 Version 1, dynamically linked, not stripped The executable for test_hmac is created from the source 05-test_hmac.t, and it will be located at. The command below is an example for tracking down a failure in the HMAC test suite Since you already know there's a problem, you can build the problem test with the following. You typically run make test to validate the library after make'ing. config no-asm -DNDEBUG -g3 -O0 -fno-omit-frame-pointerĬFLAG =-m64 -Wall -DL_ENDIAN -O3 -pthread -DFILIO_H -g3 -O0 -fno-omit-frame-pointer The -DNDEBUG is used to ensure Posix's assert does not crash your program while under the debugger. Not all flags will be honored, but its an improvement over -d. To ensure most of your preferred flags are used, perform the following. Operating system: i86pc-whatever-solaris2ĬFLAG =-m64 -Wall -DL_ENDIAN -O0 -g -pthread -DFILIO_H -Wa,-noexecstack However, the debugging information will lack symbolic constants because -g3 was not used: In the output below, notice -d caused the library to reduce optimizations ( -O0) and increase debugging information ( -g). Creating a debug build is as easy as using -d configure argument. The first thing you should do after verifying the bug is to create a debug build of the OpenSSL library and attempt to reproduce it. You should move to OpenSSL 1.1.x as soon as possible. As of January 2020, OpenSSL 1.0.2 is end of life. The instructions that follow help determine a failue in OpenSSL 1.0.2 and below. home/test_user/openssl-1.1.1d/util/shlib_wrap.sh /home/test_user/openssl-1.1.1d/test/ectest => 1 # Subtest: /home/test_user/openssl-1.1.1d/test/ectestĬrypto/ec/ecp_nistp521.c:144:15: runtime error: load of misaligned address 0x7ffec57b10b7 for type 'limb', which requires 8 byte alignmentĠx7ffec57b10b7: note: pointer points hereĬ2 31 7e 7e f9 9b 42 6a 85 c1 b3 48 33 de a8 ff a2 27 c1 1d fe 28 59 e7 ef 77 5e 4b a1 ba 3d 4d Ok 1 - require '/home/test_user/openssl-1.1.1d/test/recipes/' $ PERL5LIB=util/perl TOP=$PWD perl test/recipes/15-test_ec.t You can run a specific test by setting PERL5LIB and TOP variables as shown below.
