Subject: [RFC][PATCH 0/6] KEYS: Fixes


Hi James,

Here's a collection of fixes for Linux keyrings, mostly thanks to Eric
Biggers, if you could pass them along to Linus.  They include:

 (1) Fix some PKCS#7 verification issues.

 (2) Fix handling of unsupported crypto in X.509.

 (3) Fix too-large allocation in big_key.

The patches can be found here also:

	https://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git/tag/?h=keys-fixes-20180222

And also on the keys-fixes branch.

David
