Hi all, I'm sending out v1 of my patch series that addresses a UEFI spec non-compliance when enrolling PK in setup mode. Additional info can be found in bugzilla [1]; the changes are split into 4 patches as suggested by Laszlo Ersek in comment #4. I've based my work on the patch by Matthew Carlson; I've credited him with co-authorship of the first patch even though in the end I decided to do the implementation a bit differently. Comments & reviews welcome!

Jan, From looking over the patch 1/4 email i have a concern. In AuthService.c on the conditional change you made. Aren't we losing a case where we are evaluating a nonPK payload signed by the PK? Given the system is in SetupMode that means there is no PK but is this the conditional path that is used when installing Secure boot keys in reverse (DBX,DX,KEK,PK) order? Is there testing you have done? This code should be pretty easy to do host based unit testing on. Any chance you have authored that to confirm use cases are not unexpectedly impacted? Example of host based unit test of library is here: edk2/SecurityPkg/Library/SecureBootVariableLib/UnitTest at master · tianocore/edk2 (github.com) <https://github.com/tianocore/edk2/tree/master/SecurityPkg/Library/SecureBootVariableLib/UnitTest> Thanks Sean On 1/22/2023 10:13 PM, Yao, Jiewen wrote: > Hi Sean > I would like to hear your feedback, since it is a little different from the original MSFT patch. > > Would you please take a look? > > Thank you > Yao, Jiewen > >> -----Original Message----- >> From: Jan Bobek<jbobek@nvidia.com> >> Sent: Saturday, January 21, 2023 6:59 AM >> To:devel@edk2.groups.io >> Cc: Jan Bobek<jbobek@nvidia.com>; Laszlo Ersek<lersek@redhat.com>; Yao, >> Jiewen<jiewen.yao@intel.com> >> Subject: [PATCH v1 0/4] Don't require self-signed PK in setup mode >> >> Hi all, >> >> I'm sending out v1 of my patch series that addresses a UEFI spec >> non-compliance when enrolling PK in setup mode.

Thanks for sharing your concern! They way I think about the change is that I've replaced the expression IsPk with FeaturePcdGet (PcdRequireSelfSignedPk) && IsPk and nothing else. When you look at it this way, it's fairly easy to break down how it affects the logic: 1. Assume PcdRequireSelfSignedPk is TRUE. In this case, the two expressions are exactly the same and no change in behavior occurs, just as we want. 2. Assume IsPk is FALSE. In this case, both expressions evaluate to FALSE, no matter what the PCD is configured to. That's also good, because we don't want to change how non-PK payloads are handled. 3. In fact, the only change in behavior that occurs is when PcdRequireSelfSignedPk is FALSE and IsPk is TRUE; here the former expression would be TRUE, whereas the latter is FALSE. That's exactly what we want: we wish to enter the first block of the if-else branch (which changes the variable similarly to when we're in custom mode) rather than falling through to the third block (which checks the self-signature). To directly answer your question, I don't think the behavior changes at all when processing non-PK payloads, by virtue of IsPk being FALSE and what I said in point (2.) above. Additionally, yes, the first block of the if-else branch is exactly the path that's taken when enrolling KEK/DB/DBX in Setup mode, and one that has always been available even without Custom mode. It used to be that you couldn't use this path to enroll PK without Custom mode (precisely because of !IsPk in the condition), but I'm hoping to enable this path with my patch. Let me know if I haven't answered or misunderstood your question. > Is there testing you have done? This code should be pretty easy to do > host based unit testing on.

You could do a similar test from the OS, but in my case this was more straightforward. I am aware of the host-based unit testing library in edk2, and I agree that it would be great to have the code in AuthVariableLib tested for all the different cases. However, I don't have any such tests right now, and while I'm willing to potentially look into writing some, I'd have to do it more or less on the side, meaning it could take a while.

I read your replacement a little different. - if ((InCustomMode () && UserPhysicalPresent ()) || ((mPlatformMode == SETUP_MODE) && !IsPk)) { with + if ( (InCustomMode () && UserPhysicalPresent ()) + || ( (mPlatformMode == SETUP_MODE) + && !(FeaturePcdGet (PcdRequireSelfSignedPk) && IsPk))) + { In the upper part you replaced it says !IsPk. What am i missing? If a payload was in this function targeting a KEK change with no PK installed it would go in the original IF condition. In the new code it would because device is not in custom mode and the payload is not targeted PK.

Is it possible that you're missing the negation (i.e. exclamation mark) in front of the parethesis?

Did i mention how much i hate reviewing code over email? :) Even after looking at it a few times I missed that change. I think this change looks fine. Personally, i think this code has terrible readability and high complexity and with high impact. It would be great to at least get unit tests if not a full refactor of the library. I also think the edk2 idea of "custom mode" should be removed. But that feedback isn't for this patch and I don't think this patch should be held up just because the surrounding code is less than ideal. For patch 1 and 4.
