GSoC tip: Try to spread your proposals out. If we don't have enough project slots for you, all your 3 proposals get rejected and your GSoC participation goes out the window.
Take a look at our project ideas and ask questions, and take a look at other orgs if you want. Also, don't forget that these project ideas are just suggestions, and you're free (and encouraged) to
build on top of them, or write your own proposal from scratch.

i can submit up to three proposals. I'll give all of this some thought and a little research and start putting at least two proposals together starting Friday. :)On Wed, Apr 13, 2022, 15:15 Marvin Häuser <mhaeuser@...> wrote:On 13.

I'm on board with not treating EFI as an operating system. the more i think
about it the more it looks like scope creep.Agreed.I'm not quite as enthusiastic
about it as i was at first glance.
I'm still keen on doing my gsoc proposal for edk, though, and even if this
task and the acpica application are decided to be out of scope unit
testing,How about fuzz-testing? This is also something edk2 needs quite badly. At Acidanthera, we compile edk2 code in userspace outside the edk2 build system and fuzz with dummy applications.clang integrationPedro and Vitaly are looking for someone to finish ASan: https://edk2.groups.io/g/devel/topic/90010978#87991There are working UBSan concepts, but they also need to be mainlined.and source-level debugging are all relevant to
how about your ideas for security stuff?I want the entirety of MM to leverage SmmMemLib and to support SMAP. SmmMemLib would then handle UEFI->MMRAM and BaseMemoryLib would only work on MMRAM. Also evaluation of how to best avoid pointers in MM communication buffers would be nice.There also is a bunch of other stuff, like working out moving a part of CpuDxe into DxeCore to have memory protection live immediately, memory protection in PEI, a replacement for the TE format (it’s buggy and most platforms mostly abandoned it over various issues), and alternatives to guarding critical code with SMM (like allowing NVRAM commits only as part of a reboot).I personally find all of those projects very important, but I cannot promise many people agree. Especially those that impose global changes (most notably the TE replacement) may be very tedious to submit. Gladly, I believe you can submit multiple proposals (?)Best regards,MarvinI'm not very knowledgeable about
trusted platform or secure boot but I'm willing to learn whatever is
necessary to get something spun up for my proposal.

I have no particular use case in mind for it, but I see itspotential for anybody developing larger applications in that when a libraryis changed there's no need to distribute a new version of the whole binary,just the relevant library module.I really do not like the trend of treating UEFI as a full-fledged OS - itis not. The most used UEFI applications, OS loaders, are really not thathuge and are distributed as part of the OS image anyway. Even for less usedapplications, you will always get a full snapshot anyhow. Gladly we don’thave auto-update and package management yet. :)I slept on it and it occurred to me that the whole thing could operatesimilarly to the shell protocol in that the linker/loader is itself anapplication that does a LoadImage() on the application needing dynamiclinking facilities.That would mean the linker itself is shipped with every application thatrequires it? Otherwise it doesn’t make much sense for it to be an app andbelow’s problems apply.If however the whole plan is making the linker as a DXE and including itwith the firmware, that I'm not quite as sure about. That would necessarilytie any applications using dynamic linking to TianoCore or any firmwaredistribution that derives from it.I think that was the idea referred to as “edk2 core” by Steven, but I’dlike to hear his proposal to be sure. Virtually everyone uses edk2, so thatitself is not the problem, but versioning is. Vendors are slow to updatetheir snapshots or have just given up doing that entirely. Distributing itfor external applications like OS loaders would mean this can be leveragedprobably no earlier than 10 years from now. And for in-firmware things, Ihave a hard time thinking about a use-case that outweighs the drawbacks.To shift the topic slightly back to GSoC, however, I'm willing to workon other items on the task list. Unit testing and an ACPICA application arethe alternative projects I had thought about. I need to choose fairly soonas the proposal deadline is next Tuesday. I know a tiny bit about portingACPICA as I also have plans to incorporate it into my own project.I have a few more ideas for security stuff, but Nate did not confirm themas appropriate yet and I’m not here to drive you away from this specifictask (or the others). However, I’m still curious and concerned. :)Best regards,Marvin
