Hi Linus, Please pull this fix for a bug introduced with '82f94f24475c ("KEYS: Provide software public key query function [ver #2]")'. The following changes since commit ccda4af0f4b92f7b4c308d3acc262f4a7e3affad: Linux 4.20-rc2 (2018-11-11 17:12:31 -0600) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security.git fixes-v4.20-rc3 for you to fetch changes up to fd35f192e42cf7c0df1e2480bfd5965e35b2f4ca: integrity: support new struct public_key_signature encoding field (2018-11-13 13:09:56 -0800) ---------------------------------------------------------------- Mimi Zohar (1): integrity: support new struct public_key_signature encoding field security/integrity/digsig_asymmetric.c | 1 + 1 file changed, 1 insertion(+) --- commit fd35f192e42cf7c0df1e2480bfd5965e35b2f4ca Author: Mimi Zohar <zohar@linux.ibm.com> Date: Fri Nov 9 00:53:40 2018 -0500 integrity: support new struct public_key_signature encoding field On systems with IMA-appraisal enabled with a policy requiring file signatures, the "good" signature values are stored on the filesystem as extended attributes (security.ima). Signature verification failure would normally be limited to just a particular file (eg. executable), but during boot signature verification failure could result in a system hang. Defining and requiring a new public_key_signature field requires all callers of asymmetric signature verification to be updated to reflect the change. This patch updates the integrity asymmetric_verify() caller.
