I looked at the latest webrev:

Which is good to me.

I am not on the PKCS#11 committee and not sure about the plan.
As for which one is right, I am more inclined to the "spec is right" side which
is also what NSS picked.
Comparing between spec and header, shouldn't the former get more eyeballs in
terms of review?
The header file also has a deprecated structure CK_AES_GCM_PARAMS which
contains both ulIvLen and ulIvBits fields.
As ulIvBits and ulIvLen are essentially same in terms of meaning except bytes
vs bits. Having both just creates confusion and potential inconsistency and
makes not much sense to me.

Solaris 11.4"
Will the inconsistency structure be continue? I was just wondering if
OpenHSM2/Solaris/NSS will fix the bug and use one structure in the
future, then we may not need to workaround the issue in the calling side.
I had a quick look the PKCS#11 3.0 draft, there is no update of the
structure yet.

Anyone has time to help review this fix? PKCS#11 v2.40 has
inconsistent definition for CK_GCM_PARAMS struct. The mechanism spec
(sec 2..12.3) has:
typedef struct CK_GCM_PARAMS {
CK_BYTE_PTR pIv;
CK_ULONG ulIvLen;
CK_BYTE_PTR pAAD;
CK_ULONG ulAADLen;
CK_ULONG ulTagBits;
} CK_GCM_PARAMS;
However, the header file pkcs11t.h has an extra "ulIvBits" field:
typedef struct CK_GCM_PARAMS {
CK_BYTE_PTR pIv;
CK_ULONG ulIvLen;
* CK_ULONG ulIvBits;*
CK_BYTE_PTR pAAD;
CK_ULONG ulAADLen;
CK_ULONG ulTagBits;
} CK_GCM_PARAMS;
Some vendors such OpenHSM2 and Solaris go with the header file while
some vendor such as NSS go with the mech spec. Current SunPKCS11
provider impl works with NSS but not with other vendors whose
CK_GCM_PARAMS struct contains ulIvBits field. Based on testing
results, OpenHSM2 and Solaris error out at init time when the
parameter length does not have their expected value. Thus, one way to
workaround this inconsistency is to re-try with a different structure
for AES GCM when the init failed. In addition, given the parameters
contains Iv and AAD which some vendor may use during subsequent
enc/dec operations, I changed to use the same model as RSASSA-PSS to
defer the freeing after the enc/dec operation is finished. Verified
the changes on Solaris 11.4 against existing GCM regression tests.
