2013-11-12fix verify_mok()Andrew Boie
() Fix the return value semantics. If the MokList doesn't exist, we are OK. If the MokList was compromised but we were able to erase it, that is OK too. Only if the list can't be nuked do we return an error. () Fix use of potentially uninitialized attribute variable () Actually use the return value when called from verify_buffer.

2013-11-06Fix check logic for SetupMode variable.Peter Jones
After going back and inspecting this further, the logic for "SetupMode" being present at all was incorrect. Also initialize our state earlier so it's sure to always be set. Signed-off-by: Peter Jones <pjones@redhat.com>

2013-10-28We should be checking both mok and the system's SB settingsPeter Jones
When we call hook_system_services(), we're currently only checking mok's setting. We should use secure_mode() instead so it'll check both. Signed-off-by: Peter Jones <pjones@redhat.com>

2013-10-23Revert "additional bounds-checking on section sizes"Peter Jones
This reverts commit 21e40f0174814b3d91836e38c7cf95c8f2f1f3a4. In principle I like the idea of what's going on here, but generate_hash() really does need to have the expected result.

2013-10-22Don't reject all binaries without a certificate database.Peter Jones
If a binary isn't signed, but its hash is enrolled in db, it won't have a certificate database. So in those cases, don't check it against certificate databases in db/dbx/etc, but we don't need to reject it outright. Signed-off-by: Peter Jones <pjones@redhat.com>

This adds additional bounds-checking on the section sizes. Also adds -Wsign-compare to the Makefile and replaces some signed variables with unsigned counteparts for robustness. Signed-off-by: Kees Cook <kees@ubuntu.com>

2013-10-02Add support for disabling db for verificationJosh Boyer
Provide a mechanism for a physically present end user to disable the use of db when doing 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 the use of db for verification purposes (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 cause shim to not use db for verification purposes. If db is to be ignored, shim will export a runtime variable called 'MokIgnoreDB' for the OS to query at runtime. Signed-off-by: Josh Boyer <jwboyer@fedoraproject.org>
