2012-10-23Fix password hash calculationMatthew Garrett
This was hardcoded, rather than being based on the actual password length, resulting in incorrect hashes being generated.

2012-10-23Delete MokList properlyMatthew Garrett
A cut and paste error meant that attempts to delete MokList were instead appending a zero-length addition.

The pointer to the certificate needs to be incremented by the size of the entire certificate, not just the certificate data.

2012-10-23Support a vendor-specific DBX list.Peter Jones
In some rare corner cases, it's useful to add a blacklist of things that were allowed by a copy of shim that was never signed by the UEFI signing service. In these cases it's okay for them to go into a local dbx, rather than taking up precious flash. Signed-off-by: Peter Jones <pjones@redhat.com>

2012-10-18Add MOK password authMatthew Garrett
Add support for setting an MOK password. The OS passes down a password hash. MokManager then presents an option for setting a password. Selecting it prompts the user for the same password again. If they match, the hash is enrolled into a boot services variable and MokManager will prompt for the password whenever it's started.

If a callback returns any kind of failure, wait for a keypress in order to give the user an opportunity to read any failure messages.

2012-10-18Add support for disabling signature verificationMatthew Garrett
Provide a mechanism for a physically present end user to disable signature verification. This is handled by the OS passing down a variable that contains a UINT32 and a SHA256 hash. If this variable is present, MokManager prompts the user to choose whether to enable or disable signature validation (depending on the value of the UINT32). They are then asked to type the passphrase that matches the hash. This then saves a boot services variable which is checked by shim, and if set will skip verification of signatures.

2012-10-12Reallocate the DevPath space for the volume labelGary Ching-Pang Lin
The size of the DevPath string array was not sufficient to append the volume label. This patch extends the size for the label and re-enables the menu freeing.

2012-10-12Remove LoadImage/StartImage supportMatthew Garrett
Some systems will show an error dialog if LoadImage() returned EFI_ACCESS_DENIED, which then requires physical user interaction to skip. Let's just remove the LoadImage/StartImage code, since the built-in code is theoretically equivalent.

2012-10-12Switch to using db format for MokList and MokNewMatthew Garrett
Using the same format as the UEFI key databases makes it easier for the kernel to parse and extract keys from MOK, and also permits MOK to contain multiple key or hash types. Additionally, add support for enrolling hashes.

In theory vendors could blacklist binaries with SHA1, so make sure we calculate and check that hash as well.
