[pkg-cryptsetup-devel] Bug#758788: cryptsetup: Passphrase caching broken in decrypt_keyctl

[Marek Królikowski]

Package: cryptsetup
Version: 2:1.6.6-1
Severity: normal

Dear Maintainer,
after upgrade to 2:1.6.6-1 I have to enter passphrase for each of crypttab entries. 
Desired behavior is for cryptsetup to try cached passphrase for crypptab entries with
the same identifier (pw1 in this case).

Working configurations:
- cryptsetup 2:1.6.4-4
- cryptsetup 2:1.6.6-1 with decrypt_keyctl copied from 2:1.6.4-4
