Subject[GIT PULL] Security subsystem fixes for v4.16-rc3
Please pull these updates, which include:

- Keys fixes via David Howells:

"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."

- Seccomp updates via Kees Cook:

"Please pull these seccomp changes for v4.16-rc3. These are fixes for
the get_metadata interface that landed during -rc1. While the new
selftest is strictly not a bug fix, I think it's in the same spirit of
avoiding bugs."

And also an IMA build fix from Randy Dunlap.
