v8: bugfixes, comment cleanups, etc.
It's been a little while since my last posting of this series. Not a lot
has changed in this series since then. This is mostly addressing review
comments on the v7 posting. Many thanks to Eric, Xiubo and Luis for
helping review the last set.
There are a few smaller bugfixes, some comment fixes, and a new helper
to determine the length of a ceph_fscrypt_auth field was added.
This support requires changes to the MDS that are currently being
tracked here:
https://github.com/ceph/ceph/pull/41284
This patchset also requires a patch that's not yet in tree from Eric
Biggers:
[PATCH] fscrypt: align Base64 encoding with RFC 4648 base64url
Hopefully, that will go into v5.15.
Work continues on the content piece, but I don't think we want to merge
any of this until we have a fully-working prototype. I'm planning to
send a ceph+fscrypt state of the union email in a bit that covers the
state of the larger project.
Stay tuned...
