Bug 1603628 Update NSS to handle PKCS #11 v3.0 r=ueno r=mt
Update to PKCS #11 v3.0 part 2.
Create the functions and switch to the C_Interface() function to
fetch the PKCS #11 function table. Also PKCS #11 v3.0 uses a new
fork safe interface. NSS can already handle the case if the PKCS #11
module happens to be fork safe (when asked by the application to
refresh the tokens in the child process, NSS can detect that such a
refresh is not necessary and continue. Softoken could also be put in
fork_safe mode with an environment variable. With this patch it's
the default, and NSS asks for the fork safe API by default.
Technically softoken should implement the old non-fork safe
interface when PKCS #11 v2.0 is called, but NSS no longer needs it,
and doing so would double the number of PKCS #11 interfaces are
needed. You can still compile with fork unsafe semantics, and the
PKCS #11 V3.0 module will do the right thing and not include the
fork safe flag. Firefox does not fork(), so for firefox this is
simply code that is no longer compilied.
We now use C_GetInterface, which allows us to specify what kind of
interface we want (PKCS #11 v3.0, PKCS #11 v2.0, fork safe, etc.).
Vendor specific functions can now be accessed through the
C_GetInterface. If the C_GetInterface function does not exists, we
fall bak to the old C_GetFunctionList.
There are 24 new functions in PKCS #11 v3.0: C_GetInterfaceList -
return a table of all the supported interfaces C_GetInterface -
return a specific interface. You can specify interface name, version
and flags separately. You can leave off any of these and you will
get what the token thinks is the best match of the interfaces that
meet the criteria. We do this in softoken by the order of the
interface list. C_SessionCancel - Cancel one or more multipart
operation C_LoginUser - Supply a user name to C_Login(). This
function has no meaning for softoken, so it just returns
CKR_OPERATION_NOT_INITIALIZED under the theory that if we in the
future want to support usernames, the NSS db would need special
initialization to make that happen. C_Message* and C_*Message* (20
functions in all) are the new AEAD interface (they are written
generally so that it can be used for things other than AEAD). In
this patch they are unimplemented (see the next patch).
This patch adds regular (NSC_) and FIPS (FC_) versions of these
functions. Also when creating the PKCS #11 v2.0 interface, we had to
create a 2.0 specific version of C_GetInfo so that it can return a
2.40 in the CK_VERSION field rather than 3.00. We do this with
#defines since all the function tables are generated automagically

Bug 1623184 - Clear ECX prior to cpuid, fixing query for Extended
While trying to benchmark the recent HACL* AVX2 code, I noticed that
it was not being called on two machines (that both support AVX2),
instead using only the AVX version.
In order to query for Extended Features (cpuid with EAX=7), we also
need to set ECX to 0: https://www.intel.com/content/www/us/en
developer-vol-2a-manual.html. The current code fails to do this,
resulting in flags that show no support.
Initially, I wrote a separate `freebl_cpuid_ex` function that
accepted a value for ECX as a separate input argument. However, some
definitions of `freebl_cpuid` already zero ECX, so making this
consistent is the simplest way to get the desired behavior.
With this patch, the two test machines (MacOS and Linux x64)
correctly use the AVX2 ChaCha20Poly1305 code.

Bug 1603628 Update NSS to handle PKCS #11 v3.0 r=daiki r=mhoye
This patch implements the first phase: updating the headers.
lib/util/pkcs11.h lib/util/pkcs11f.h lib/util/pkcs11t.h
Were updated using the released OASIS PKCS #11 v3.0 header files.
lib/util/pkcs11n.h was updated to finally deprecate all uses of
A new define as added: NSS_PKCS11_2_0_COMPAT. If it's defined, the
small semantic changes (including the removal of deprecated defines)
between the NSS PKCS #11 v2 header file and the new PKCS #11 v3 are
reverted in favor of the PKCS #11 v2 definitions. This include the
removal of CK?_NETSCAPE_? in favor of CK?_NSS_?.
One notable change was caused by an inconsistancy between the spec
and the released headers in PKCS #11 v2.40. CK_GCM_PARAMS had an
extra field in the header that was not in the spec. OASIS considers
the header file to be normative, so PKCS #11 v3.0 resolved the issue
in favor of the header file definition. NSS had the spec definition,
so now there are 2 defines for this structure:
CK_NSS_GCM_PARAMS - the old nss define. Still used internally in
freebl. CK_GCM_PARAMS_V3 - the new define. CK_GCM_PARAMS - no longer
referenced in NSS itself. It's defined as CK_GCM_PARAMS_V3 if
NSS_PKCS11_2_0_COMPAT is *not* defined, and it's defined as
CKM_NSS_GCM_PARAMS if NSS_PKCS11_2_0_COMPAT is defined.
Softoken has been updated to accept either CK_NSS_GCM_PARAMS or
CK_GCM_PARAMS_V3. In a future patch NSS will be updated to use
CK_GCM_PARAMS_V3 and fall back to CK_NSS_GMC_PARAMS.
One other semantic difference between the 3.0 version of pkcs11f.h
and the version here: In the oasis version of the header, you must
define CK_PKCS11_2_0_ONLY to get just the PKCS #11 v2 defines. In
our version you must define CK_PKCS11_3 to get the PCKS #11 v3
Most of this patch is to handle changing the deprecated defines that
have been removed in PCKS #11 v3 from NSS.

Bug 1608250 KBKDF - broken fipstest handling of KI_len r=rrelyea
When testing Bug 1608245, I realized that I had inadvertently broken
fipstest.c's handling of KI and KI_len. This lead to it passing
bogus keys (with unusually large lengths exceeding the bounds of
sizeof KI) to kbkdf_Dispatch(...).
This uses Bob Relyea's suggestion on how to handle this: detect the
size of KI when processing the mech selection, storing KI_len there.
This simplifies reading of the KI value in later code.
Bug 1608245 KBKDF - Consistently handle NULL slot/session r=kjacobs
Patch by cipherboy, review by kjacobs.
Per Bug 1607955, the KBKDF code introduced in Bug 1599603 confused
Coverity with a elided NULL check on
sftk_SlotFromSessionHandle(...). While Coverity is incorrect (and
the behavior is fine as-is), it isn't consistent with the KBKDF
code's handling of sftk_SessionFromHandle(...) (which is NULL
This brings these two call sites into internal consistency.
