fscrypt.git/cli-tests/t_v1_policy.out, branch v0.2.8 Go tool for managing Linux filesystem encryption cmd/fscrypt: improve errors 2020-05-09T22:21:31+00:00 Eric Biggers ebiggers@google.com 2020-05-09T21:52:07+00:00 181600d6327ed34a3f62eda0dd03a6d2ae49e5f9 In checkEncryptable(), check whether the directory is already encrypted before checking whether it's empty. Also improve the error message for when a directory is nonempty. Finally, translate keyring.ErrKeyAddedByOtherUsers and keyring.ErrKeyFilesOpen into errors which include the directory. 
In checkEncryptable(), check whether the directory is already encrypted
before checking whether it's empty.

Also improve the error message for when a directory is nonempty.

Finally, translate keyring.ErrKeyAddedByOtherUsers and
keyring.ErrKeyFilesOpen into errors which include the directory.

Try to detect incomplete locking of v1-encrypted directory 2020-05-09T22:16:13+00:00 Eric Biggers ebiggers@google.com 2020-05-09T21:17:17+00:00 de51add609bc74b7247ec4776bd694abbea24a45 'fscrypt lock' on a v1-encrypted directory doesn't warn about in-use files, as the kernel doesn't provide a way to easily detect it. Instead, implement a heuristic where we check whether a subdirectory can be created. If yes, then the directory must not be fully locked. Make both 'fscrypt lock' and 'fscrypt status' use this heuristic. Resolves https://github.com/google/fscrypt/issues/215
