Hello,

I have implemented solution to sign the u-boot and zImage with CST tool. Now I would like to implement CST tool to work with HSM module. I already have PKI tree generated on the HSM. I created the CST tool with back_end-hsm, create hsm.cfg file with path to the certificate and run CST tool. After a moment I get error Segmentation fault (core dumped). With cst tool located in /linux64/bin/cst there is no problem to sign the image, but with back_end-hsm I get segmentation fault. (CST 3.1.0 and also with CST 3.2.0)

EDIT:

I am using module libsc-hsm-pkcs11.so, error is on the line 589 (ENGINE_ctrl_cmd_string (eng, "MODULE_PATH", hsm_conf.module_path, 0);)

Thank you for any idea.

Best regards

Tomas Klein

Correct Answer

I solve the problem by moving the Engine constructor (ENGINE *engine_hsm (void); - e_hsm.c, line: 124), from C file to to e_hsm.h (files path: cst-3.1.0/release/code/back_end-hsm/src)

I did the same. But this doesn't work.

Does it have anything to do with version of openssl ? I am using the openssl 1.1.1 with Ubuntu18.04

In our case, we also using openssl version 1.1.1, cst 3.1.0 and library to comunicate with HSM (GitHub - CardContact/sc-hsm-embedded: PKCS#11 and CSP-Minidriver library for the SmartCard-HSM and STARCOS based signatu… )

Do u have any steps u had already followed. ?

This is the error i got after using cst-hsm compilation

cst[20371]: segfault at ffffffff8cdac980 ip 00007fa5b8c56fbc sp 00007ffc19f0f320 error 5 in libcrypto.so.1.1[7fa5b8b04000+29b000]

this is the configuration I am using. Even i tried static compilation of those.

ldd /usr/bin/openssl
   linux-vdso.so.1 (0x00007ffe39bd5000)
   libssl.so.1.1 => /usr/lib/x86_64-linux-gnu/libssl.so.1.1 (0x00007fdeefe05000)
   libcrypto.so.1.1 => /usr/lib/x86_64-linux-gnu/libcrypto.so.1.1 (0x00007fdeef93a000)
   libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fdeef71b000)
   libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fdeef32a000)
   libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007fdeef126000)
   /lib64/ld-linux-x86-64.so.2 (0x00007fdef0345000)

I solve the problem by moving the Engine constructor (ENGINE *engine_hsm (void); - e_hsm.c, line: 124), from C file to to e_hsm.h (files path: cst-3.1.0/release/code/back_end-hsm/src)

Where exactly you moved the line ?
