I solved this.
TLDR: I'm working from git://git.code.sf.net/p/trousers/tpm-tools
trousers-tpm-tools. The getPass() utility method used on the 1.3.9 branch/tag
doesn't work for me. I needed to pick up changes from 'master', and it works.
Some more info:
The terminal/prompt logic was overhauled at some point, so I think I'm just
suffering from bad legacy behavior:

tpm_utils: reimplement _get_pass to replace the obsolete get_pass().

I based my work from the 1.3.9 tag/branch, for stability (silly me). But, it
seems the getPass() method refactor never made it there. I confirmed that the
plain 1.3.9 branch also exhibits this error on my machine.

Subject: TPM-Tools password prompt
Hi all,
I'm extending the tpm-tools and using the console input handling methods used
by the rest of the utilities.
I'm building all the tools myself, including my new tools, but the "Enter owner
password:" prompt isn't working right: I enter my password, then hit ENTER, but
it blows right past the "Confirm Password" prompt, which I obviously didn't
have time to input, and fails for "Passwords didn't match"
> Enter new owner password: {password entered and click ENTER}
> Confirm password: Passwords didn't match { didn't stop here for my input }
It does this for my new tools as well as existing tools that I build without
modification. Also note that the Trousers tpm-tools package installed on my
machine (Ubuntu 14.04) does not exhibit this behavior, only the ones I build.
Here's my code:
if (!owner_well_known) {
// Prompt for owner password
szTpmPasswd = GETPASSWD(_("Enter owner
password: "), &tpm_len, TRUE);
if (!szTpmPasswd){
printf("ERROR: Failed to get
owner password.\n");
goto abort;
}
} else {
szTpmPasswd = (char *)well_known_secret;
}
Where GETPASSWD is defined in the tpm-tools project. This is pretty straight
forward, so I don't know what's wrong.
The problem must be something in my build, but I don't know where to start.
Can someone here point me in the right direction to fix this?
Thanks,
