Problem
When using a custom password for TPM, the OEM re-ownership process is broken
Impact
The OEM re-ownership process breaks for any user setting a custom password and not just using 12345678
First appeared
6923fb5e20
Detail
on line 498, if blank, the TPM custom password is overwritten with TPM_PASS_DEF (eg, when no custom password is set by the user installing)
```
if [ "$TPM_PASS" == "" ]; then TPM_PASS=$TPM_PASS_DEF; fi
```
so far so good. $TPM_PASS should be used for all TPM interaction from this point. $TMP_PASS_DEF is now a disposed of variable.
we see that happens when resetting the TPM on line 712 (generate_checksums) is that $TPM_PASS is used (correctly)
```## reset TPM and set password
if [ "$CONFIG_TPM" = "y" ]; then
echo -e "\nResetting TPM...\n"
tpmr reset "$TPM_PASS" >/dev/null 2>/tmp/error
---SNIP
```
The TPM now has either the custom password of the user, or the default of 12345678 depending on user selection.
On line 712, we duck into the generate_checksums sub, which for some reason reverts to TPM_PASS_DEF
```
# create Heads TPM counter
if [ "$CONFIG_TPM" = "y" ];then
if [ "$CONFIG_IGNORE_ROLLBACK" != "y" ]; then
tpmr counter_create \
-pwdo "$TPM_PASS_DEF" \
--SNIP
```
This then, rightly, fails due to
```
Authentication failed (Incorrect Password) (ox1) from TPM_CreateCounter
```

valid or the repeated password doesn't match, so the user can try
again.

Don't hash password used to seal an object. This limits the password
to 32-characters but avoids obfuscating the usage of the password. The

lower already (GPG token limits to 25 chars). We may allow >32 char
passwords in the future by hashing only if the password is >32 chars.
Always pass passwords as hex to tpm2-tools to avoid possible ambiguity

Set flags 'fixedtpm|fixedparent|adminwithpolicy'. Plain password auth
is no longer allowed. For objects sealed with a password, the password

tpm2 unseal -c 0x81000003 -p "<password>"
This now correctly returns an error indicating this auth method is not
allowed.

* sign, decrypt: Not applicable to a sealed object, tpm2_create
automatically removed these from the defaults.
* fixedtpm, fixedparent: Kept
* sensitivedataorigin: Not applicable an object where the sensitive

Most logic throughout Heads doesn't need to know TPM1 versus TPM2 (and
shouldn't, the differences should be localized). Some checks were
incorrect and are fixed by this change. Most checks are now unchanged
relative to master.
There are not that many places outside of tpmr that need to
differentiate TPM1 and TPM2. Some of those are duplicate code that
should be consolidated (seal-hotpkey, unseal-totp, unseal-hotp), and
some more are probably good candidates for abstracting in tpmr so the
business logic doesn't have to know TPM1 vs. TPM2.
Previously, CONFIG_TPM could be variously 'y', 'n', or empty. Now it
is always 'y' or 'n', and 'y' means "any TPM". Board configs are
unchanged, setting CONFIG_TPM2_TOOLS=y implies CONFIG_TPM=y so this
doesn't have to be duplicated and can't be mistakenly mismatched.
There were a few checks for CONFIG_TPM = n that only coincidentally
worked for TPM2 because CONFIG_TPM was empty (not 'n'). This test is
now OK, but the checks were also cleaned up to '!= "y"' for robustness.

- init tries to bind fd and fails currently
- Note: Check if whiptail is different of fbwhiptail in clearing screen. As of now every clear seems to be removed, still whiptail clears previous console output
- When no OS' /boot can be mounted, do not try to TPM reset (will fail)
- seal-hotpkey is not working properly
- setting disk unlock key asks for TPM ownership passphrase (sealing in NV requires ownership, but text is misleading user as if reowning TPM)
- We should cache input, feed tpm behind the scene and wipe passphrase and state clearly that this is TPM disk unlock kye passphrase.
- primary key from TPM2 is invalid most of the time from kexec-select-boot and verifying global hashes but is setuped correctly at disk unlock key setup
- would be nice to take advantage of bash function tracing to understand where we are for debugging purposes, code takes ash in consideration only
- tpmr says it implements nv calls but actually doesn't. Removing those falsely wrapped functions would help.
- Implementing them would be better
- REVIEW TODOS IN CODE
- READD CIRCLECI CONFIG
Current state:
- TPM unseal works without disk unlock key and generates TOTP properly (was missing die condition at unseal to not produce always good TOTP even if invalid)
- TPM disk encryption key fails. Hypothesis is that sealing with USB drivers loaded and measures in inconsistent with sealed with/without.
- TPM disk unsealing happens without USB modules being loaded in non-HOTP setup. This fails.
- Current tests are with fbwhiptail (no clear called so having traces on command line of what happens)
- Testing with HOTP implementation for sealing/unsealing since that forces USB module loads on each boot to remove this from failing possibilities
- Add TRACE function tracing output under etc/functions, depending on CONFIG_ENABLE_FUNCTION_TRACING_OUTPUT enabled in board configs
- Replace current DEBUG to TRACE calls in code, reserving DEBUG calls for more verbose debugging later on (output of variables etc)
- add 'export CONFIG_ENABLE_FUNCTION_TRACING_OUTPUT=y' in qemu-coreboot(fb)whiptail-tpm1(-hotp) boards to see it in action
- kexec-save-default extracts initrd crypttab files and creates /boot/kexec_initrd_crypttab_overrides.txt entries pointing to /secret.key
- kexec-insert-key applies /boot/kexec_initrd_crypttab_overrides.txt to replace initrd's crypttabs files pointing to inserted /secret.key through cpio
- Both scripts inform the user of applied magic on screen
Not all distro put crypttab under /etc/ within initramfs, but finding it at
runtime needs unpacking, which may be hard to do, so it is made overridable
with a file at /boot/kexec_initrd_crypttab_path.txt, whose content could be
obtained with $ cpio -t < ${uncompressed_initrd} | grep crypttab .
The "target" field of the record within the crypttab stored in the root
file system for the luks container which is going to be unlocked via
kexec-insert-key should be modified into the same "luks-$uuid" format,
otherwise the boot sequence will get stuck when OS is trying to unlock them
again, in order to map them according to "target" fields written in the
crypttab stored in the root fs.
Adds check to detect device formatted as fat32 without partition table.
With fat32 fdisk does not print message about invalid partition table
and instead it'll print an empty table with header.
In both cases total output has the same length of 5 lines: 3 about
device info, 1 empty line and the 5th will be the table header or
invalid partition message.

2. whiptail itself allows escape characters such as \n

only generate a diff to display to the user, if an actual issue is

Above changes squashed in this commit.
Since /etc/luks-functions are currently exporting passphrases tested good per cryptsetup to be reused in the code,
the logic calling both luks_reencrypt and luks_change_passphrase testing for non-empty luks_current_Disk_Recovery_Key_passphrase
was bogus.
This commit includes a new variable luks_new_Disk_Recovery_Key_desired which is set when reencryption is desired.
The 3 use cases (reencrypt+passphrase change, reencrypt no passphrase change and passphrase change alone now only test
for luks_new_Disk_Recovery_Key_desired and luks_new_Disk_Recovery_Key_passphrase_desired, nothing else.
network-init-reovery can be used to automatically set RTC clock to obtained NTP clock.
The script would fail if other devices devices previously registered on the network with the same MAC.
Consequently, maximized boards are detected here, and a full random MAC is generated and used instead of using hardcoded DE:AD:C0:FF:EE.
This continues to generate checksums and sign them per new GPG User PIN, but does not set a default boot option.
The user hitting Default Boot on reboot will go through having to setup a new boot default, which will ask him to setup a Disk Unlock Key if desired.
Otherwise, hitting Default Boot goes into asking the user for its Disk Recovery Key passphrase, and requires to manually setup a default boot option.
Simplify the menu options by removing the duplication of the entry name
in the menu selections; instead, use clear verbiage to distinish
