Based on the following package with changes to merge into CryptoPkg.

https://github.com/microsoft/mu_plus/tree/dev/201908/SharedCryptoPkg

* Add X509ConstructCertificateStackV() to BaseCryptLib.  This is required to
  have a VA_LIST version of X509ConstructCertificateStack() so it can be
  maped into a Protocol/PPI.
* Add EDK II Crypto Protocols/PPIs/PCDs
* Add PEIM, DXE Driver, SMM Driver that produce the EDK II Crypto Protocols/PPIs
  using the services of the BaseCryptLib and TlsLib with families of services
  and individual services enabled/disables in the Protocols/PPIs using a PCD.
* Add new BaseCryptLib library instance that calls the EDK II Crypto
  Protocols/PPIs.
* Update DSC file to build all modules/libs and provide ability to build binary
  versions of the PEIM, DXE Driver, SMM Driver with different sets of Crypto
  services enabled.

This patch series depends on the following patches that must be committed 
before this patch series will build and pass EDK II CI.

https://bugzilla.tianocore.org/show_bug.cgi?id=2420

Add X509ConstructCertificateStackV() to BaseCryptLib that is
identical in behavior to X509ConstructCertificateStack(), but
it takes a VA_LIST parameter for the variable argument list.

The VA_LIST form of this function is required for BaseCryptLib
functions to be wrapped in a Protocol/PPI.

https://bugzilla.tianocore.org/show_bug.cgi?id=2420

Based on the following package with changes to merge into
CryptoPkg.

https://github.com/microsoft/mu_plus/tree/dev/201908/SharedCryptoPkg

Add the EDK II Crypto Protocol, EDK II SMM Crypto Protocol
and EDK II Crypto PPI that provide the same services as the
BaseCryptLib.  One additional GetVersion() services is provided
to support backward compatible extensions to these new
Protocols/PPIs if new services are added to BaseCryptLib in the
future.  The EDK II Crypto Protocols/PPIs are located in a
private directory so they are only available CryptoPkg components.

In order to optimize the size of modules that produce the
EDK II Crypto Protocols/PPIs define a FixedAtBuild PCD
gEfiCryptoPkgTokenSpaceGuid.PcdCryptoServiceFamilyEnable.
This PCD is type VOID* and is associated with the structure
PCD_CRYPTO_SERVICE_FAMILY_ENABLE.  This structure contains
bitfields and unions that allow a platform DSC files to
enable/disable entire families of services or enable/disable
individual services in the produced EDK II Crypto
Protocols/PPIs.

  To: devel; +Cc: Jian J Wang, Xiaoyu Lu

https://bugzilla.tianocore.org/show_bug.cgi?id=2420

Based on the following package with changes to merge into
CryptoPkg.

https://github.com/microsoft/mu_plus/tree/dev/201908/SharedCryptoPkg

Add the CryptoPei, CryptoDxe, and CryptoSmm modules that produce
EDK II Crypto Protocols/PPIs that provide the same services as
the BaseCryptLib class.

In order to optimize the size of CryptoPei, CryptoDxe, and
CryptoSmm modules for a specific platform, the FixedAtBuild
PCD gEfiCryptoPkgTokenSpaceGuid.PcdCryptoServiceFamilyEnable
is used to determine if a specific service is enabled or
disabled.  If a service is enabled, then a call is made to
the BaseCryptLib service.  If the service is disabled, then
a DEBUG() message and ASSERT() are performed and a default
return value is returned.  This provides simple detection
of a service that is disabled but is used by another module
when DEBUG()/ASSERT() macros are enabled.

The use of a FixedAtBuild PCD is required so the compiler
and linker know each services enable/disable setting at
build time and allows disabled services to be optimized away.

CryptoPei supports both pre-mem and post-mem use cases.
If CryptoPei is initially dispatched pre-mmem, the the
register for shadow service is used so the Crypto PPI can
be reinstalled post-mem.

From: Michael D Kinney @ 2020-01-30  7:00 UTC (permalink / raw)
  To: devel; +Cc: Jian J Wang, Xiaoyu Lu

https://bugzilla.tianocore.org/show_bug.cgi?id=2420

Based on the following package with changes to merge into
CryptoPkg.

https://github.com/microsoft/mu_plus/tree/dev/201908/SharedCryptoPkg

Add the PeiCryptLib, DxeCryptLib, and SmmCryptLib instances
of the BaseCryptLib library classes that are implemented using
the services of EDK II Crypto Protocols/PPIs.

These library instances all set a dependency expression on the
EDK II Crypto Protocols/PPIs, so any modules that use these
library instances are not dispatched until the modules that
produce the EDK II Crypto Protocols/PPIs are dispatched.

  To: devel; +Cc: Jian J Wang, Xiaoyu Lu

https://bugzilla.tianocore.org/show_bug.cgi?id=2420

Based on the following package with changes to merge into
CryptoPkg.

https://github.com/microsoft/mu_plus/tree/dev/201908/SharedCryptoPkg

Add Crypto library instances and modules that consume/produce
the EDK II Crypto Protocols/PPIs to the CryptoPkg DSC file.

The default build of CryptoPkg performs a package verification
build.

The CRYPTO_SERVICES define is added that supports the following
settings.

* PACKAGE         - Package verification build of all components.  Null
                    versions of libraries are used to minimize build times.
* ALL             - Build PEIM, DXE, and SMM drivers.  Protocols and PPIs
                    publish all services.
* NONE            - Build PEIM, DXE, and SMM drivers.  Protocols and PPIs
                    publish no services.  Used to verify compiler/linker
                    optimizations are working correctly.
* MIN_PEI         - Build PEIM with PPI that publishes minimum required
                    services.
* MIN_DXE_MIN_SMM - Build DXE and SMM drivers with Protocols that publish
                    minimum required services.

I wonder how platforms are expected to determine their minimal PCD bitmaps.

In the static linking case, the linker sees all sites that (a) call the
crypto functions, (b) take the addresses of crypto functions. Therefore
the linker can eliminate unused functions with certainty.

If we switch to dynamic linking, we save space between independent
modules, but we will not easily know what crypto functions are globally
used (and, un-used) between all modules.

Dynamic coverage testing seems risky. If we miss something, then in a
RELEASE build, the missing function will not even crash the system, but
pretend some action and return a default value (IIUC). That might allow
the issue to spread out, and cause symptoms at distant locations. (This
sounds really dangerous for crypto, so I think I'd prefer a hard crash,
on the spot). Either way, safety requirements appear to conflict with
space saving goals.

I tried to find a method for statically deriving the necessary set of
functions (basically, ask the linker or the object files about the
*wrapper* crypto APIs that are actually called), but I came up empty.

And then there's the other direction too -- we don't just want to enable
a service that we initially missed (and caught with an ASSERT() in a
DEBUG build), we also want to disable a service that is not used
*anymore*, after e.g. removing a module from a firmware build, or after
slimming down a module. How will we notice such opportunities for
"trimming" the protocol?

I think the static PCD is a great mechanism, but we need some automated
way ("policy") too, for calculating the PCD for a given platform.

This is not to say that the series should not go in as-is -- it's huge,
and I can't offer a review better than this mere email, so I'm not
trying to say anything like go/no-go. It's just that in OVMF I wouldn't
even attempt to come up with the right bitmaps, I'd just set "give me
everything" for safety -- and that might actually consume more space in
the flash than statically linking just a handful (?) of functions into 5
modules.

(To clarify: by "we", I don't mean "Red Hat", I mean the upstream
community. I.e. the above is not a vendor-side evaluation, but a general
platform perspective. OVMF is used just as an example that I'm familiar
with.)

With the DevicePathLib and PrintLib instances that defer to a protocol,
I think the *proportions* are a bit different. I feel it's not difficult
for a platform firmware to put most of the DevicePathLib / PrintLib APIs
to use (i.e. the duplication due to static linking may be significant),
plus the protocol implementations themselves can be "complete", because
they are not huge (i.e., even if the protocols are provided at some net
loss in space, the loss is not serious).

Again: this is not a review either way, I'm just asking: how is a
platform supposed to calculate the minimal service bitmaps for the PCD?

Thanks
Laszlo

Hi Laszlo,

Great feedback.  The reason I chose to use a Structured PCD
is to provide maximum flexibility.  I agree we should review
the behavior in RELEASE builds when a call is made to a 
service that is disabled.  Perhaps REPORT_STATUS_CODE would
be a good option for a platform provide its own handler for
that condition.
 
Platforms have a few choices for use of BaseCryptLib and
TlsLib services:

1) No changes from today.  Continue to statically link them
   into modules.  As modules change their usage, the linker
   takes care of everything.

2) Switch to the dynamic services through Protocols/PPIs
   and each platform is responsible for their own analysis
   and setting the Structured PCD for the PEI, DXE, SMM
   module.  I agree some additional guidance and/or tools
   may be required for a platform to have high confidence 
   in their Structured PCD settings.  Of course build time
   detection is preferred over runtime detection.

3) EDK II community defines a small number of profiles
   for the PEI, DXE, SMM versions of these modules and
   publishes released binaries for each profile.  Platforms
   integrate the published binary modules.  This may 
   provide more services than are required for some platforms
   but has the advantage of using a released binary from
   the EDK II project and reducing build times.  Once again,
   some guidance and/or tools may be required to help the
   EDK II community determine the right number of profiles
   and the services enabled in each profile.

I agree with your summary of the risks associated with the 
use of dynamic services.  Each platform will have to make
an assessment of those risks and choose to use this feature
or not.  Adding this feature to the EDK II will allow
platforms to try the feature on dev/debug builds first and
decide if they want to use the static or dynamic services for
their release builds.  That may also result in creative ideas
on how to get accurate accounting on service usage and work
towards a build time detection mechanism to know exactly what
services are used.

Best regards,

Mike

This sounds super interesting; I didn't think of it!

The great property of profiles seems to be that they strike a middle
ground between space savings and call safety. Namely:

- let's say we define 4 profiles,

- each profile comes with its own *wrapper* crypto API lib instance,

- in each such lib instance, the wrapper functions for those PPI /
protocol member APIs that are disabled in the PCD are *also not
implemented*, thereby causing linkage failures if a module tries to use them

- given that there are only 4 profiles, a platform can exhaustively test
building against each, and find the smallest one that works -- and
repeatably so: it's never a "bad time" to attempt building against a
smaller profile!

- in the smallest applicable profile, some functions might be included
uselessly in the PPI / protocol providers -- but not too many. That's
why we didn't pick a larger profile. And whatever is included, will be
shared between consumers.

This should work even without distributing the PPI / protocol providers
in binary form.

I think this could be a valid use case for some library instances in
edk2 *not* to implement all functions from the library class header.

Thanks!
Laszlo
