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
