dbx x64 version is 267 after failed update 77 -> 217 #2

Closed nre closed 2 years ago

nre commented 2 years ago

Describe the bug Updating dbx x64 77 -> 217 "failed to run update on reboot" but now fwupd says the version is 267.

What dbx version do I actually have now?

Steps to Reproduce I cannot reproduce it because dbx cannot be downgraded. The steps were:

  1. $ fwupdmgr refresh
  2. $ fwupdmgr get-updates
  3. $ fwupdmgr update
  4. Reboot.

Expected behavior dbx to be updated to 217 or remain at 77.

fwupd version information

$ fwupdmgr --version ``` runtime org.freedesktop.fwupd 1.7.5 compile org.freedesktop.gusb 0.3.10 runtime com.dell.libsmbios 2.4 runtime org.kernel 5.15.0-48-generic compile org.freedesktop.fwupd 1.7.5 runtime org.freedesktop.gusb 0.3.10 ```

apt default installation on Ubuntu 22.04.1 (upgraded from 20.04.4).

Additional questions

hughsie commented 2 years ago

What dbx version do I actually have now?

If you update fwupd to 1.8.5 or 1.7.10 the versions will be a bit less random: https://github.com/fwupd/fwupd/commit/eec6de6985f6d4a8d1d758fb7c8863c1f92b02df

nre commented 2 years ago

Snap 1.8.5-10-g34dfa8689 says the dbx version is 217, which seems like good news. Was fwupd mistaken about the update failing? Was the incorrect version number the cause of that confusion?

It's all explained in the comment:

/*
 * Microsoft seems to actually remove checksums in UEFI dbx updates, which I'm guessing is
 * a result from OEM pressure about SPI usage -- but local dbx updates are append-only.
 *
 * That means that if you remove hashes then you can have a different set of dbx checksums
 * on your machine depending on whether you went A->B->C->D or A->D...
 *
 * If we use the metric of "count the number of SHA256 checksums from MS" then we might
 * overcount (due to the now-removed entries) -- in some cases enough to not actually apply
 * the new update at all.
 *
 * In these cases look at the *last* dbx checksum and compare to the set we know to see if
 * we need to artificially lower the reported version. This isn't helped by having *zero*
 * visibility in the reason that entries were removed or added.
 *
 * This also fixes the DBX update 20200729 which added 4 duplicate entries, which should be
 * rectified during the SetVariable(), so they're only really a problem for transactional
 * size limits. But we all noticed that load-bearing *should* word there, didn't we.

My point was that fwupd was wrong about "failed to run update on reboot".

fu_engine_update_history_device checks whether the device version is the update version. But if it isn't, instead of checking whether the device version is something unexpected, it falls back to "failed to run update on reboot". I think this is a problematic default because the wiki entry sounds like it can be ignored as a known issue.

dbx isn't alone in having unexpected versions. Lenovo is having a problem with Intel ME versions too.
