RE: EFIBootGuard for CIP and SecureBoot

by daniel.sangorrin＠toshiba.co.jp

Hello Francois, Jan, Christian, and all Sorry for the late reply, I was waiting for the administrator of the Boot Architecture mailing list to accept my subscription request, but it seems it will take a bit more time. I will send this reply and hope it will not be blocked. I have also added the u-boot mailing list to Cc, as Tom suggested (although I'm not a member), the CIP mailing list, Jan Kiszka (one of the main developers of Efibootguard) and Christian (an expert in software updates). Background: during the last Linaro connect in Bangkok I was told that Linaro Edge (LEDGE) were working on a secure software update mechanism based on UEFI capsules that would flash firmware updates from a UEFI application, instead of using a Linux agent such as SWUpdate. Then, I had an online meeting with Francois, director of LEDGE. I explained to Francois that in CIP we are using the Linux agent approach right now, and we are also considering the use of a UEFI application (Efibootguard) to arm a watchdog and deal with the state-machine variables (installed, testing, ok, failed..) needed for A/B software updates. Efibootguard sounds like an excellent place to collaborate with Linaro (particularly on the watchdog drivers front) because it does not strictly depend on where the firmware is flashed (UEFI capsule or Linux agent). > On Fri, Apr 19, 2019 at 12:48:51PM +0200, Francois Ozog wrote: > > Hi Daniel, > > > > We will be conducting a UEFI gap analysis to support EFIBootGuard in U-Boot. > > > > As we are working on UEFI SecureBoot implementation in U-Boot, how do > > you expect the boot process to be secured?

Efibootguard is composed of two parts. - A UEFI application that can arm a watchdog and decide what environment (kernel, boot args, etc.) to use next depending on a set of variables (update status, highest revision, etc.) stored in FAT16 partitions. - A Linux application that can read and set those variables from Linux (similar to u-boot's fw_setenv). This functionality is also available in the form of a library. As far as I know, there is no concept of "Secure Booting" in Efibootguard at the moment. Adding signature checks before booting into the selected kernel would be a possible solution. Thanks, Daniel

StandaloneMM discussion

by Ilias Apalodimas

Hi all, This started as an internal discussion for U-Booa and SSL which quickly span out of control, so the mailing list is a better suited place for this discussion. Akashi-san had an interesting idea. Since we will try to implement StandaloneMM as an OP-TEE TA, why not add payload authentication capabilities on it. Since it's already doing variable authentication on the secure side, the needed changes would be minimal (at least that's what i think, please correct me if i am wrong), since most of the code should already be there. This means that the payload authentication will be moved to the secure world. Although doing the authentication in secure world won't offer any security enhancements, the common code across firmware implementations is probably nice to have. The obvious drawback is that you limit the payload authentication capabilities, since running StMM will become obligatory for image that. Thanks /Ilias

EBBR Plugfest at ELC and/or ELC-E

by Grant Likely

Hi Bill and Peter, [cc'ing boot-architecture to trawl for additional volunteers] As discussed during EBBR monthly call today, we should have an EBBR plugfest at ELC and/or ELC-E this year with the goal of working out compatibility issues between platforms+firmware and OS images (distro images, OpenEmbedded, Buildroot, Yocto builds, etc). My initial thought is to run a full day event that is part hacking sprint and part plugfest. We could ask participants to either bring a platform (SBC with firmware installed) or an OS images and then set up a test matrix for each OS to test on each board. After an initial set of attempts the rest of the day could be a hacking sprint to solve problems and squash bugs. I'm only going to be at ELC this year (Aug 21-23rd in San Diego). I might be able to get the LF to provide a co-located room Tuesday the 20th. ELC-E will be in late October. If we do this at both events, then someone will need to take the lead on organizing the European version. Thoughts? g.

Shutting down arm.ebbr-discuss@arm.com mailing list

by Grant Likely

As discussed at Linaro Connect BKK19 in early April, the arm.ebbr-discuss mailing list isn't very functional because it doesn't have a public archive and non-Arm folks cannot subscribe themselves. I'm shutting down the arm.ebbr-discuss mailing list. From this date all EBBR discussion will be held on the boot-architecture(a)linaro.org mailing list. g.

EBBR Monthly Meeting - 23 April 2019

by Grant Likely

Hi all, The EBBR monthly meeting is later today. We're in the quiet period after releasing EBBR v1.0 and are unlikely to add new content immediately. Instead, we'll use the monthly meeting to track and discuss progress on Secure Boot with U-Boot, TF-A, and OP-TEE, as well as other desired EBBR features. As those features mature, we'll add language to EBBR to match. Dial in details below. g. --- There is a monthly conference call to discuss EBBR topics on the 4th Tuesday of the month at 15:00 UTC/BST, 7:00 PST/PDT, 23:00/22:00 CST (following UTC/BST daylight savings time shifts). Anyone is welcome to join. Online meeting: https://arm-onsite.webex.com/meet/gralik01 Phone 1-408-792-6300 Call-in toll number (US/Canada) 1-877-668-4490 Call-in toll-free number (US/Canada) 44-203-478-5285 Call-in toll number (UK) 08-002061177 Call-in toll-free (UK) More access numbers: webex-global-numbers Access code: 809 053 990

Re: EFIBootGuard for CIP and SecureBoot

The UEFI spec is quite clear about this: An implementation of SecureBoot will check the signature of any EFI binary before starting it. StartImage() will return EFI_SECURITY_VIOLATION when trying to start an image that is neither correctly signed nor whose hash is known. As we use StartImage() for starting any image the signature of EFIBootGuard would be checked first and then any of the child applications it starts. You will not be able to start GRUB or the Linux kernel if their signature are not added to U-Boot's key database. Of cause you could implement inside EFIBootGuard your own mechanism to start a loaded image without calling StartImage(). In this case U-Boot cannot protect you from invalid images.

EFIBootGuard for CIP and SecureBoot

by Francois Ozog

Hi Daniel, We will be conducting a UEFI gap analysis to support EFIBootGuard in U-Boot. As we are working on UEFI SecureBoot implementation in U-Boot, how do you expect the boot process to be secured? Would U-Boot UEFI SecureBoot verify EFIBootGuard signature and in turn EFIBootGuard will check either grub or Linux signature? Please elaborate on your vision of a secured boot process. Cheers FF PS: you may want to subscribe to the boot-architecture mailing list in Linaro.
