Following along the same lines as per the user-space fix. Right now this isn't really an issue with the ceph kernel driver because of the feature bit laginess, however, that can change over time (when the new snaprealm info type is ported to the kernel driver) and depending on the MDS version that's being upgraded can cause message decoding issues - so, fix that early on.

ceph: make num_fwd and num_retry to __u32
The num_fwd in MClientRequestForward is int32_t, while the num_fwd in ceph_mds_request_head is __u8. This is buggy when the num_fwd is larger than 256 it will always be truncate to 0 again. But the client couldn't recoginize this.
This will make them to __u32 instead. Because the old cephs will directly copy the raw memories when decoding the reqeust's head, so we need to make sure this kclient will be compatible with old cephs. For newer cephs they will decode the requests depending the version, which will be much simpler and easier to extend new members.

ceph: drop messages from MDS when unmounting
When unmounting all the dirty buffers will be flushed and after the last osd request is finished the last reference of the i_count will be released. Then it will flush the dirty cap/snap to MDSs, and the unmounting won't wait the possible acks, which will ihold the inodes when updating the metadata locally but makes no sense any more, of this. This will make the evict_inodes() to skip these inodes.
If encrypt is enabled the kernel generate a warning when removing the encrypt keys when the skipped inodes still hold the keyring:

For encrypted inodes, transmit a rounded-up size to the MDS as the normal file size and send the real inode size in fscrypt_file field. Also, fix up creates and truncates to also transmit fscrypt_file.
When we get an inode trace from the MDS, grab the fscrypt_file field if the inode is encrypted, and use it to populate the i_size field instead of the regular inode size field.

When setting a directory's crypt context, ceph_dir_clear_complete() needs to be called otherwise if it was complete before, any existing (old) dentry will still be valid.
This patch adds a wrapper around __fscrypt_prepare_readdir() which will ensure a directory is marked as non-complete if key status changes.

ceph: add support to readdir for encrypted names
To make it simpler to decrypt names in a readdir reply (i.e. before we have a dentry), add a new ceph_encode_encrypted_fname()-like helper that takes a qstr pointer instead of a dentry pointer.
Once we've decrypted the names in a readdir reply, we no longer need the crypttext, so overwrite them in ceph_mds_reply_dir_entry with the unencrypted names. Then in both ceph_readdir_prepopulate() and ceph_readdir() we will use the dencrypted name directly.

ceph: decode alternate_name in lease info
Ceph is a bit different from local filesystems, in that we don't want to store filenames as raw binary data, since we may also be dealing with clients that don't support fscrypt.
We could just base64-encode the encrypted filenames, but that could leave us with filenames longer than NAME_MAX. It turns out that the MDS doesn't care much about filename length, but the clients do.
To manage this, we've added a new "alternate name" field that can be optionally added to any dentry that we'll use to store the binary crypttext of the filename if its base64-encoded value will be longer than NAME_MAX. When a dentry has one of these names attached, the MDS will send it along in the lease info, which we can then store for later usage.

ceph: send alternate_name in MClientRequest
In the event that we have a filename longer than CEPH_NOHASH_NAME_MAX, we'll need to hash the tail of the filename. The client however will still need to know the full name of the file if it has a key.
To support this, the MClientRequest field has grown a new alternate_name field that we populate with the full (binary) crypttext of the filename. This is then transmitted to the clients in readdir or traces as part of the dentry lease.
Add support for populating this field when the filenames are very long.

ceph: encode encrypted name in ceph_mdsc_build_path and dentry release
Allow ceph_mdsc_build_path to encrypt and base64 encode the filename when the parent is encrypted and we're sending the path to the MDS. In a similar fashion, encode encrypted dentry names if including a dentry release in a request.
In most cases, we just encrypt the filenames and base64 encode them, but when the name is longer than CEPH_NOHASH_NAME_MAX, we use a similar scheme to fscrypt proper, and hash the remaning bits with sha256.
When doing this, we then send along the full crypttext of the name in the new alternate_name field of the MClientRequest. The MDS can then send that along in readdir responses and traces.

ceph: fscrypt_auth handling for ceph
Most fscrypt-enabled filesystems store the crypto context in an xattr, but that's problematic for ceph as xatts are governed by the XATTR cap, but we really want the crypto context as part of the AUTH cap.
Because of this, the MDS has added two new inode metadata fields: fscrypt_auth and fscrypt_file. The former is used to hold the crypto context, and the latter is used to track the real file size.
Parse new fscrypt_auth and fscrypt_file fields in inode traces. For now, we don't use fscrypt_file, but fscrypt_auth is used to hold the fscrypt context.
Allow the client to use a setattr request for setting the fscrypt_auth field. Since this is not a standard setattr request from the VFS, we add a new field to __ceph_setattr that carries ceph-specific inode attrs.
Have the set_context op do a setattr that sets the fscrypt_auth value, and get_context just return the contents of that field (since it should always be available).

This is slightly less efficient, and we may want to eventually allow using RCU when the leaf dentry isn't encrypted.

ceph: preallocate inode for ops that may create one
When creating a new inode, we need to determine the crypto context before we can transmit the RPC. The fscrypt API has a routine for getting a crypto context before a create occurs, but it requires an inode.
Change the ceph code to preallocate an inode in advance of a create of any sort (open(), mknod(), symlink(), etc). Move the existing code that generates the ACL and SELinux blobs into this routine since that's mostly common across all the different codepaths.
In most cases, we just want to allow ceph_fill_trace to use that inode after the reply comes in, so add a new field to the MDS request for it (r_new_inode).
The async create codepath is a bit different though. In that case, we want to hash the inode in advance of the RPC so that it can be used before the reply comes in. If the call subsequently fails with -EJUKEBOX, then just put the references and clean up the as_ctx. Note that with this change, we now need to regenerate the as_ctx when this occurs, but it's quite rare for it to happen.
