Subject: [PATCH 0/6] Several device-mapper fixes

This series contains several miscellaneous fixes to input validation in
device-mapper.  The only potentially controversial commits should be the
last two, which prevent creating devices named ".", "..", or "control".
The other patches fix input validation problems that have existed since
at least the beginning of git history.

Demi Marie Obenour (6):
  device-mapper: Check that target specs are sufficiently aligned
  device-mapper: Avoid pointer arithmetic overflow
  device-mapper: structs and parameter strings must not overlap
  device-mapper: Avoid double-fetch of version
  device-mapper: Refuse to create device named "control"
  device-mapper: "." and ".." are not valid symlink names
