2017-05-04fscrypt: correct collision claim for digested namesEric Biggers1-13/+9
As I noted on the mailing list, it's easier than I originally thought to create intentional collisions in the digested names. Unfortunately it's not too easy to solve this, so for now just fix the comment to not lie. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
2017-05-04fscrypt: introduce helper function for filename matchingEric Biggers1-0/+78
Introduce a helper function fscrypt_match_name() which tests whether a fscrypt_name matches a directory entry. Also clean up the magic numbers and document things properly. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
2017-02-06fscrypt: split supp and notsupp declarations into their own headersEric Biggers1-0/+66
Previously, each filesystem configured without encryption support would define all the public fscrypt functions to their notsupp_* stubs. This list of #defines had to be updated in every filesystem whenever a change was made to the public fscrypt functions. To make things more maintainable now that we have three filesystems using fscrypt, split the old header fscrypto.h into several new headers. fscrypt_supp.h contains the real declarations and is included by filesystems when configured with encryption support, whereas fscrypt_notsupp.h contains the inline stubs and is included by filesystems when configured without encryption support. fscrypt_common.h contains common declarations needed by both.
