Description Nathanael Noblet 2010-07-16 16:55:17 EDT
Created attachment 432498 [details]
Patching rc.sysinit to attempt a password when the key is unavailable

Description of problem:
When configuring a luks encrypted partition/filesystem if you add a keyfile to it and add that to /etc/cryptab, if the keyfile isn't available, rc.sysinit doesn't give the user an attempt to enter the password.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Add a keyfile to /etc/crypttab
2. Don't have it available on boot
3.
  
Actual results:
Dropped to emergency shell

Expected results:
Fallback to requesting a password. Then perhaps after a few password attempts dropping to the shell would then be appropriate.

I'm not sure this is really a great fallback - it's essentially an invalid configuration.
Comment 2 Nathanael Noblet 2010-07-26 16:17:39 EDT
Not really... I've configured a key that is stored on a usb stick, if it isn't plugged in in time I should still get a password prompt. That's why there are 8 password slots, you can have master keys, master passwords etc... Imagine a system where there is a master key on USB stored by maybe the manufacturer/supplier/support to unlock a device, but normally uses passwords.... lots of potential uses for a fallback.
Comment 3 Nathanael Noblet 2010-08-25 15:28:42 EDT
or even if it was possible to specify a fallback method in the options portion of the crypttab ? So specify the path to a keyfile, but in the options specify that falling back to a password prompt is allowed..?
Comment 4 Bill Nottingham 2011-02-28 15:39:35 EST
Given that systemd (which we use for crypttab in F-15 onwards) doesn't do this, I'm not intending to add this for initscripts for older releases.

Moving to systemd, where it could be considered as a RFE.
Comment 5 Fedora Admin XMLRPC Client 2011-10-20 12:29:18 EDT
This package has changed ownership in the Fedora Package Database.  Reassigning to the new owner of this component.
Comment 6 Jóhann B. Guðmundsson 2012-01-24 06:23:05 EST
Is this still a problem or can this bug be closed or moved to an RFE?
Comment 7 Nathanael Noblet 2012-01-24 16:20:22 EST
I'd love to know if there is any way to have fallback/alternative unlock methods for encrypted partitions, however this particular bug could probably be cloased if this isn't the right medium to figure it out/discuss.
Comment 8 Jóhann B. Guðmundsson 2012-01-26 17:02:28 EST
Adding this to fit and finish tracker bug.
Comment 9 Jóhann B. Guðmundsson 2012-02-20 06:51:38 EST
Given that we will be only back porting important fixes for F15 at this point
in time I'm moving this RFE against Rawhide so it does not get forgotten or
lost in the EOL process.
