[GIT PULL] keys: Collected minor fixes and cleanups

[David Howells]

Hi Linus,

Here's a set of minor keyrings fixes/cleanups that I've collected from
various people for the upcoming merge window.

A couple of them might, in theory, be visible to userspace:

 (*) Make blacklist_vet_description() reject uppercase letters as they
     don't match the all-lowercase hex string generated for a blacklist
     search.

     This may want reconsideration in the future, but, currently, you can't
     add to the blacklist keyring from userspace and the only source of
     blacklist keys generates lowercase descriptions.

 (*) Fix blacklist_init() to use a new KEY_ALLOC_* flag to indicate that it
     wants KEY_FLAG_KEEP to be set rather than passing KEY_FLAG_KEEP into
     keyring_alloc() as KEY_FLAG_KEEP isn't a valid alloc flag.

     This isn't currently a problem as the blacklist keyring isn't
     currently writable by userspace.

The rest of the patches are cleanups and I don't think they should have any
visible effect.

I've fixed the compilation error, added another patch and rebased to
v5.11-rc4 since the last request.

David
