Hi James,
I have a number of sets of patches for you to pull. I've git-merged them
together into a single branch (keys-next) as there are some conflicts and
tagged the end.
The component subsets are:
(1) Tag keys-preparse-1-20140707
A set of patches that mostly convert extant key types to perform
preparsing to make it possible to determine the amount of quota in
advance.
I haven't fixed the encrypted and trusted keys as yet as they incorrectly
use the ->update() op, but I'd like to get the changes I have done out
the door.
(2) Tag keys-pkcs7-20140708
A set of patches that can parse binary PKCS#7 messages and verify the
X.509 certificates and signatures contained therein and look to see if
there's an intersection between those certificates/signatures and a ring
of trusted keys.
This has a conflict with (1) that is solved in the merge: A debugging key
type is added for testing the PKCS#7 parser and this uses the user
keyring type.
(3) Tag keys-pefile-20140709
A set of patches that take a signed PE binary, extract the PKCS#7
message, validate the signature of the signed parts of the PE binary and
verify the PKCS#7 certificate using (2) above.
Subsets (2) and (3) will then be used to do signed kexec.
(4) Branch linux-integrity/next-with-key
Mimi and Dmitry's keyrings patches.
Note that this branch is on top of their next-without-key branch. If you
pull that first as Mimi has asked, git should connect this correctly.
This is commit 7d2ce2320e8efdc4a6dcbae7b329ed3f0d1cd778.
(5) Branch keys-fixes
Three fixes:
(a) Allow CAP_SYS_ADMIN capable processes to invalidate keys that are
appropriately marked.
This has a conflict with (4) since both add new key flags.
(b) Don't select MPILIB_EXTRA as it doesn't exist.
(c) Select CRYPTO if SIGNATURE is enabled rather than depending on it to
get module vs built-in correct.
There's some duplicate code between the patches in (2) and (4) for looking up
a key containing a public key. The code exists in different places and
doesn't interfere with each other, so I'll deal with it later when one or both
of these sets has gone in.
