## Description:

This update for cryptsetup fixes the following issues:

Changes in cryptsetup:

  * Fix for (bsc#1270254) to avoid undesired pinning of all volume keys (via the
    thread keyring) through the caller's credentials when the kernel opens a
    file. This is due to the refactoring in kernel commit a28d893eb327 ("md:
    port block device access to file") that accidentally causes the caller's
    thread keyring to be kept alive long beyond the caller's lifetime, the
    kernel part is tracked in (bsc#1270252).

  * Add keyring key type. [b6fb6fc0]

  * Load volume keys in intermediary keyring linked in thread keyring.
    [413a3dd0]
  * Use unique intermediary keyring name per device. [04ef07a7]
  * Add regression tests. [bfcb0c38, bb5e8e9f, e6573494, aa214c09]
