[PATCH 00/36] ceph+fscrypt: context, filename, symlink and size handling support

[Jeff Layton <jlayton@kernel.org>]

I've not posted this in a while, so I figured it was a good time to do
so. This patchset is a pile of the mostly settled parts of the fscrypt
integration series. With this, pretty much everything but the actual
content encryption in files now works.

This series is also in the wip-fscrypt-size branch of the ceph-client
tree:

    https://github.com/ceph/ceph-client/tree/wip-fscrypt-size

It would also be nice to have an ack from Al Viro on patch #1, and from
Eric Biggers on #2-5. Those touch code outside of the ceph parts. If
they aren't acceptable for some reason, I'll need to find other ways to
handle them.

Jeff Layton (31):
  vfs: export new_inode_pseudo
  fscrypt: export fscrypt_base64url_encode and fscrypt_base64url_decode
  fscrypt: export fscrypt_fname_encrypt and fscrypt_fname_encrypted_size
  fscrypt: add fscrypt_context_for_new_inode
  fscrypt: uninline and export fscrypt_require_key
  ceph: preallocate inode for ops that may create one
  ceph: crypto context handling for ceph
  ceph: parse new fscrypt_auth and fscrypt_file fields in inode traces
  ceph: add fscrypt_* handling to caps.c
  ceph: add ability to set fscrypt_auth via setattr
  ceph: implement -o test_dummy_encryption mount option
  ceph: decode alternate_name in lease info
  ceph: add fscrypt ioctls
  ceph: make ceph_msdc_build_path use ref-walk
  ceph: add encrypted fname handling to ceph_mdsc_build_path
  ceph: send altname in MClientRequest

  libceph: add CEPH_OSD_OP_ASSERT_VER support
  ceph: size handling for encrypted inodes in cap updates
  ceph: fscrypt_file field handling in MClientRequest messages
  ceph: get file size from fscrypt_file when present in inode traces
  ceph: handle fscrypt fields in cap messages from MDS

Luis Henriques (1):
  ceph: don't allow changing layout on encrypted files/directories

Xiubo Li (4):
  ceph: add __ceph_get_caps helper support
  ceph: add __ceph_sync_read helper support
  ceph: add object version support for sync read
  ceph: add truncate size handling support for fscrypt
