Subject: [PATCH] shared/tpm2-util: Fix "Error: Esys invalid ESAPI handle
|
||
|
(40000001)" warning
|
||
|
|
||
|
systemd-cryptenroll complains (but succeeds!) upon binding to a signed PCR
|
||
|
policy:
|
||
|
|
||
|
$ systemd-cryptenroll --unlock-key-file=/tmp/passphrase --tpm2-device=auto
|

|
--tpm2-public-key=... --tpm2-signature=..." /tmp/tmp.img

ERROR:esys:src/tss2-esys/esys_iutil.c:394:iesys_handle_to_tpm_handle() Error: Esys invalid ESAPI handle (40000001).

New TPM2 token enrolled as key slot 1.
|
||
|
|
||
|
The problem seems to be that Esys_LoadExternal() function from tpm2-tss
|
||
|
expects a 'ESYS_TR_RH*' constant specifying the requested hierarchy and not
|
||
|
a 'TPM2_RH_*' one (see Esys_LoadExternal() -> Esys_LoadExternal_Async() ->
|
||
|
iesys_handle_to_tpm_handle() call chain).
|
||
|
|
||
|
It all works because Esys_LoadExternal_Async() falls back to using the
|
||
|
supplied values when iesys_handle_to_tpm_handle() fails:
|
||
|
|
||
|
r = iesys_handle_to_tpm_handle(hierarchy, &tpm_hierarchy);
|
||
|
if (r != TSS2_RC_SUCCESS) {
|
||
|
...
|
||
|
tpm_hierarchy = hierarchy;
|
||
|
}
|
||
|
|
||
|
Note, TPM2_RH_OWNER was used on purpose to support older tpm2-tss versions
|
||
|
(pre https://github.com/tpm2-software/tpm2-tss/pull/1531), use meson magic
|
||
|
to preserve compatibility.
