Subject: Re: [edk2-devel] [PATCH v7 00/14] Add the VariablePolicy feature
Date: Tue, 22 Sep 2020 15:35:46 +0000	[thread overview]
Message-ID: <SN6PR11MB331296F17CA8D40768FFACA9B63B0@SN6PR11MB3312.namprd11.prod.outlook.com> (raw)
In-Reply-To: <20200828055127.1610-1-brbarkel@microsoft.com>

Bret,

If someone has given same comments as below, please just ignore them. Sorry
for the late feedback.

Patch 09: LockVariablePolicy () is called inside a debug macro. In release build it
will be replaced with empty. If this is really what you want, please add comments
in code to explain your purpose.
    ASSERT_EFI_ERROR (LockVariablePolicy ());

Patch 13: The file name VariableLockRequstToLock.c has a typo
    'Requst' -> 'Request'

Patch 02, 03, 04, 09, 12, 13, 14 have many inconsistent coding style, especially
the spaces in function/macro calling. For example,

  AllocatePool( NewSize );    vs    DumpVariablePolicy (NULL, &TempSize);

Please refer to "EDK II C Coding Standards Specification" ch5.2.2 "Horizontal Spacing"
for details.

With above addressed (for patch 01-04, 09-14),
     Acked-by: Jian J Wang <jian.j.wang@intel.com>

> Subject: [edk2-devel] [PATCH v7 00/14] Add the VariablePolicy feature
> 
> The 14 patches in this series add the VariablePolicy feature to the core,
> deprecate Edk2VarLock (while adding a compatibility layer to reduce code
> churn), and integrate the VariablePolicy libraries and protocols into
> Variable Services.
> 
> Since the integration requires multiple changes, including adding libraries,
> a protocol, an SMI communication handler, and VariableServices integration,
> the patches are broken up by individual library additions and then a final
> integration. Security-sensitive changes like bypassing Authenticated
> Variable enforcement are also broken out into individual patches so that
> attention can be called directly to them.
> 
> Platform porting instructions are described in this wiki entry:
> https://github.com/tianocore/tianocore.github.io/wiki/VariablePolicy-Protocol-
> --Enhanced-Method-for-Managing-Variables#platform-porting
> 
> Discussion of the feature can be found in multiple places throughout
> the last year on the RFC channel, staging branches, and in devel.
> 
> Most recently, this subject was discussed in this thread:
> https://edk2.groups.io/g/devel/message/53712
> (the code branches shared in that discussion are now out of date, but the
> whitepapers and discussion are relevant).
