Hi Bastian, Thanks for adding more information here.
I've looked into the problem. The s390x should be the endian problem. While the rest (i386, armel, armhf) is due to it is 32-bits. According to the build log: https://buildd.debian.org/status/fetch.php?pkg=tpm2-tss&arch=armhf&ver=4.0.1-1&stamp=1688685120&raw=0 The test failed at Test: tcti_libtpms_remap_state_posix_fallocate_fail_test We can look into the code. First. At test/unit/tcti-libtpms.c:1097, expect_value(TPMLIB_Process, cmd, cmd); And cmd is an array. unsigned char cmd[] = {0x80, 0x01, 0x00, 0x00, 0x00, 0x0c, 0x00, 0x00, 0x01 , 0x44, 0x00, 0x00}; At test/unit/tcti-libtpms.c:136, check_expected_ptr(cmd); So the problem is actually at test/unit/tcti-libtpms.c:1097. Because it tries to convert a pointer to integer. The expect_value() of CMocka is expect_value(#func, #para, LargestIntegralType val) So that cmd is converted to Integral Type. I think we might want to use expect_memory() instead? expect_memory(#func, #para, void* mem, size_t size) So that cmd is pointer rather than converted to int. Yours, Paul
