On my ASUS Transformer Mini T103HAF [1], applying a too big dbx update from e.g. Ubuntu 24.04 beta live CD can cause Shim to refuse too boot, citing "Volume Full" despite plenty of space reported from efivars filesystem on Linux. Upon further investigation, this "Volume Full" error probably comes from tpm2->hash_log_extend_event(), as I'll demonstrate below.Step to reproduce:Download & flash Ubuntu 24.04 beta live CD to a USB drive [2]. This image contains Shim 15.8-0ubuntu1 and a secureboot-db which "Update dbx to 2023-05-09 release".Boot this image on the tablet. Upon boot, verify that efivars isn't close to full.$ df -h /sys/firmware/efi/efivarsFilesystem Size Used Avail Use% Mounted onefivarfs 128K 67K 57K 55% /sys/firmware/efi/efivarsNow reboot into the same boot image again. This time, Shim will refuse to boot, citing the following:Could not create MokListRT: Volume fullCould not create MokListXRT: Volume fullCould not create SbatlevelRT: Volume fullCould not create MokListTrustedRT: Volume fullSomething has gone seriously wrong: import_mok_state() failed : Volume FullBut we've just established that efivars isn't even close to full. So what gives?4. Now disable Secure Boot, modify the boot image on the USB drive so that it boots Grub directly instead, and boot the image again. After that, enable Shim verbose mode by running sudo mokutil --set-verbosity true.5. Modify the boot image again so that it will load Shim. Boots off that. This time, you'll find the log that says:Volume FullCould not create MokListXRT: Volume Fullmok.c:926:import_one_mok_state() returning Volume Full">mok.c:798:mirror_one_mok_variable() tpm_log_event(0x73207F18, 76, 14, "MokListX")->Volume FullCould not create MokListXRT: Volume Fullmok.c:926:import_one_mok_state() returning Volume FullOr:Volume FullCould not create SbatLevelRT: Volume Fullmok.c:926:import_one_mok_state() returning Volume Full">mok.c:762:mirror_one_mok_variable() tpm_measure_variable("SbatLevel",46,0x73207F98)->Volume FullCould not create SbatLevelRT: Volume Fullmok.c:926:import_one_mok_state() returning Volume FullThe full log is available in the picture form at [3] (since I don't know how to collect the log otherwise).Here comes my analysis: both tpm_measure_variable() and tpm_log_event() calls tpm_log_event_raw() which in turns call tpm2->hash_log_extend_event(). Now, the TCG EFI Protocol Specification family 2.0 [4] section 6.6.6 specifies EFI_VOLUME_FULL as one of the possible error of EFI_TCG2_PROTOCOL.HashLogExtendEvent, describing it as "The extend operation occurred, but the event could not be written to one or more event logs". So, what I assume happens is that the full content of dbx are included into this event log, which consumes so much space it can't log any other variable, hence EFI_VOLUME_FULL "failure".Now, the reason I put "failure" in quote is because 1.) the extend operation still occurs, and 2.) go-attestation mentions in one of their vulnerability disclosure [5] that "The TCG noted that event data is meant for debugging". So, I think this error from tpm2->hash_log_extend_event() could be considered non-fatal?Note that before I come to this conclusion, I've reported this issue to Ubuntu before as [6].[1] Additional information about my device:Make & model: ASUS Transformer Mini T103HAFFirmware (BIOS) make & version: American Megatrends Inc.
