Works just fine on GA-Z170-D3H with SB Enabled.
This update has been submitted for stable by bodhi.
After updating my XPS 13 (9360) to current F34, with this shim, I cannot boot with Secure Boot enabled. The screen briefly shows
Bootloader has not verified loaded image.
System is compromised. halting.
and then shuts down. This happens with any kernel I try to boot. Boot with SB disabled works fine. Boot with SB enabled was working fine until I updated. fwupdmgr update does not show any available firmware updates.
Confirmed that after downgrading to shim-x86-15-8 I can boot with SB enabled.
I noticed that when doing so, something (shim?) briefly shows "Booting in insecure mode", though after boot, mokutil --sb-state shows SecureBoot enabled. Searching around for references on that, I found https://bugzilla.redhat.com/show_bug.cgi?id=1531961 , which claims that running mokutil --enable-validation would 'fix' it, though I can't find any explanation as to why. I ran that anyway, it asked for a password, I gave it one, it apparently completed OK.
System still does not boot with SB enabled and this shim, though. I don't know if it made the "Booting in insecure mode" message when booting with older shim go away yet (haven't checked, it's a lot of rebooting).
So poking through the code a bit I suspect https://github.com/rhboot/shim/commit/65be3503 , a bit, because it's a commit between 15 and 15.4 that touches user_insecure_mode. Just on the face of it - I may be misunderstanding - it looks like it adds a function (import_one_mok_state) that's intended to be called one-by-one on a bunch of variables and import them one at a time, but it unconditionally does user_insecure_mode = 0; at the start, whether it's reading the variable that might set it to 1 or not. So even if it's momentarily set to 1 when the relevant variable (MokSBState) is read, won't it then get set straight back to 0 by reading the next variable? Note user_insecure_mode is declared extern in shim.h, which AIUI makes it something like a global variable, right?
user_insecure_mode = 0;
Again, I may be missing something, but if so, the same may apply to ignore_db (set by MokDBState). It also is declared as extern and set unconditionally at the start of import_one_mok_state.
I'm going to test reverting that commit if possible...
I filed https://github.com/rhboot/shim/pull/362 in case I'm right about the problem and the fix.
works for me
After installing this update, my XPS 13 won't boot unless I disable secure boot. Looks like it's the same issue @adamwill has.
Works only if Secureboot is disabled, don't work if enabeld, so I'm reverting karma point.
Thinkpad T480s + UEFI + SecureBoot works fine
After orientation from javierm I enabled validation on mokutil ( sudo mokutil --enable-validation ) and my system booted fine in SB.
No regressions found
Everything seems ok.
