I haven't had a chance to read the document you wrote, but wanted to comment on xattrs. There is a hash field for each xattr (including internal xattrs), and one for the external xattr blocks that can be used to validate the xattr value. In addition to the hash for the in-inode xattrs, the inode hash itself would serve to validate the xattr values. I have a patch for e2fsprogs that checks the xattr hash for in-inode xattrs (currently it is always 0). > Please have a look at the design document and please feel free to suggest any > changes. Hopefully soon.
