[Bug 1633058] Re: ghash-clmulni-intel module fails to load

 

Can you test the following two kernels? If 4.7 is good and 4.8-rc1 is
bad, we can bisect between those two:

4.7 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7/
4.8-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8-rc1/

If both those kernels are good, we can test later 4.8 release
candidates. If they are both bad, we can test some of the 4.7 release
candidates.

Title:
  ghash-clmulni-intel module fails to load

Status in linux package in Ubuntu:
  Confirmed
Status in linux source package in Trusty:
  Confirmed
Status in linux source package in Xenial:
  Confirmed

Bug description:
  The module ghash-clmulni-intel always fails to load with "Invalid
  argument":

  $ sudo modprobe ghash-clmulni-intel
  modprobe: ERROR: could not insert 'ghash_clmulni_intel': Invalid argument

  That was caused by the commit 8996eafdc ("crypto: ahash - ensure
  statesize is non-zero"), that added a requirement that all ahash
  algorithms now need to implement import() and export() and define a
  non zero statesize.

  The fix is composed by two commits:

  3a020a7 crypto: ghash-clmulni - Fix load failure
  1a07834 crypto: cryptd - Assign statesize properly

  Xenial and Trusty are affected and Yakkety already included the
  solution above.
