C++ (Cpp) TlclDefineSpace Examples

Example #1

File: tpmtest_testsetup.c Project: Chainfire/vboot_android

int main(int argc, char** argv) {
  uint32_t perm;
  uint32_t result;
  uint32_t x;

  TlclLibInit();

  TPM_CHECK(TlclStartupIfNeeded());
  TPM_CHECK(TlclSelfTestFull());
  TPM_CHECK(TlclAssertPhysicalPresence());
  TPM_CHECK(TlclForceClear());
  TPM_CHECK(TlclSetEnable());
  TPM_CHECK(TlclSetDeactivated(0));

  result = TlclRead(INDEX0, (uint8_t*) &x, sizeof(x));
  if (result == TPM_E_BADINDEX) {
    perm = TPM_NV_PER_PPWRITE | TPM_NV_PER_GLOBALLOCK;
    TPM_CHECK(TlclDefineSpace(INDEX0, perm, sizeof(uint32_t)));
  }

  result = TlclRead(INDEX1, (uint8_t*) &x, sizeof(x));
  if (result == TPM_E_BADINDEX) {
    perm = TPM_NV_PER_PPWRITE;
    TPM_CHECK(TlclDefineSpace(INDEX1, perm, sizeof(uint32_t)));
  }

  printf("TEST SUCCEEDED\n");
  exit(0);
}

Example #2

File: rollback_index_test.c Project: Sigterm-no/vboot_reference

static uint32_t SafeDefineSpace(uint32_t index, uint32_t perm, uint32_t size) {
  uint32_t result = TlclDefineSpace(index, perm, size);
  if (result == TPM_E_MAXNVWRITES) {
    RETURN_ON_FAILURE(TPMClearAndReenable());
    result = TlclDefineSpace(index, perm, size);
    tpm_was_just_cleared = 0;
  }
  return result;
}
