-Subject: [PATCH 03/17] powerpc/ima: Add support to initialize ima policy rules
-
-PowerNV systems use a Linux-based bootloader, which rely on the IMA
-subsystem to enforce different secure boot modes. Since the
-verification policy may differ based on the secure boot mode of the
-system, the policies must be defined at runtime.
-
-This patch implements arch-specific support to define IMA policy rules
-based on the runtime secure boot mode of the system.
-
-This patch provides arch-specific IMA policies if PPC_SECURE_BOOT
-config is enabled.

-Subject: [PATCH 04/17] powerpc: Detect the trusted boot state of the system
-
-While secure boot permits only properly verified signed kernels to be
-booted, trusted boot calculates the file hash of the kernel image and
-stores the measurement prior to boot, that can be subsequently
-compared against good known values via attestation services.
-
-This patch reads the trusted boot state of a PowerNV system. The state
-is used to conditionally enable additional measurement rules in the
-IMA arch-specific policies.

-
-process_buffer_measurement() is limited to measuring the kexec boot
-command line. This patch makes process_buffer_measurement() more
-generic, allowing it to measure other types of buffer data (e.g.
-blacklisted binary hashes or key hashes).
-
-process_buffer_measurement() may be called directly from an IMA hook
-or as an auxiliary measurement record. In both cases the buffer
-measurement is based on policy. This patch modifies the function to
-conditionally retrieve the policy defined PCR and template for the IMA
-hook case.

-Subject: [PATCH 07/17] ima: Check against blacklisted hashes for files with
- modsig
-
-Asymmetric private keys are used to sign multiple files. The kernel
-currently supports checking against blacklisted keys. However, if the
-public key is blacklisted, any file signed by the blacklisted key will
-automatically fail signature verification. Blacklisting the public key
-is not fine enough granularity, as we might want to only blacklist a
-particular file.
-
-This patch adds support for checking against the blacklisted hash of
-the file, without the appended signature, based on the IMA policy. It
-defines a new policy option "appraise_flag=check_blacklist".
-
-In addition to the blacklisted binary hashes stored in the firmware
-"dbx" variable, the Linux kernel may be configured to load blacklisted
-binary hashes onto the .blacklist keyring as well. The following
-example shows how to blacklist a specific kernel module hash.
-
-  $ sha256sum kernel/kheaders.ko
-  77fa889b35a05338ec52e51591c1b89d4c8d1c99a21251d7c22b1a8642a6bad3

-
-  $ grep BLACKLIST .config

-  CONFIG_SYSTEM_BLACKLIST_HASH_LIST="blacklist-hash-list"

-
-Update the IMA custom measurement and appraisal policy
-rules (/etc/ima-policy):
-
-  measure func=MODULE_CHECK template=ima-modsig
-  appraise func=MODULE_CHECK appraise_flag=check_blacklist
-  appraise_type=imasig|modsig

-Subject: [PATCH 09/17] powerpc/powernv: Add OPAL API interface to access
- secure variable
-
-The X.509 certificates trusted by the platform and required to secure
-boot the OS kernel are wrapped in secure variables, which are
-controlled by OPAL.
-
-This patch adds firmware/kernel interface to read and write OPAL
-secure variables based on the unique key.
-
-This support can be enabled using CONFIG_OPAL_SECVAR.

-Date: Sun, 10 Nov 2019 21:10:34 -0600
-Subject: [PATCH 10/17] powerpc: expose secure variables to userspace via sysfs
-
-PowerNV secure variables, which store the keys used for OS kernel
-verification, are managed by the firmware. These secure variables need to
-be accessed by the userspace for addition/deletion of the certificates.
-
-This patch adds the sysfs interface to expose secure variables for PowerNV
-secureboot. The users shall use this interface for manipulating
-the keys stored in the secure variables.

-Subject: [PATCH 14/17] powerpc/ima: Fix secure boot rules in ima arch policy
-
-To prevent verifying the kernel module appended signature
-twice (finit_module), once by the module_sig_check() and again by IMA,
-powerpc secure boot rules define an IMA architecture specific policy
-rule only if CONFIG_MODULE_SIG_FORCE is not enabled. This,
-unfortunately, does not take into account the ability of enabling
-"sig_enforce" on the boot command line (module.sig_enforce=1).
-
-Including the IMA module appraise rule results in failing the
-finit_module syscall, unless the module signing public key is loaded
-onto the IMA keyring.
-
-This patch fixes secure boot policy rules to be based on
-CONFIG_MODULE_SIG instead.

-Subject: [PATCH 16/17] linux: configure CONFIG_I2C_OPAL as in-built.
-
-Currently, skiroot_defconfig CONFIG_I2C_OPAL is built as a loadable
-module rather than builtin, even if CONFIG_I2C=y is defined. This
-results in a delay in the TPM initialization, causing IMA to go into
-TPM bypass mode. As a result, the IMA measurements are added to the
-measurement list, but do not extend the TPM. Because of this, it is
-impossible to verify or attest to the system's integrity, either from
-skiroot or the target Host OS.
-
-Mimi Zohar <zohar@linux.ibm.com> explains more:
-
-  The concept of trusted boot requires the measurement to be added to the
-  measurement list and extend the TPM, prior to allowing access to the
-  file. By allowing access to a file before its measurement is included
-  in the measurement list and extended into the TPM PCR, a malicious file
-  could potentially prevent its own measurement from being added. As the
-  PCRs are tamper proof, measuring and extending the TPM prior to giving
-  access to the file, guarantees that all file measurements are included
-  in the measurement list, including the malicious file.
-
-  IMA needs to be enabled before any files are accessed in order to
-  verify a file's integrity and extend the TPM with the file
-  measurement.  Queueing file measurements breaks the measure and extend,
-  before usage, trusted boot paradigm.
-
-  The ima-evm-utils package includes a test for walking the IMA
-  measurement list, calculating the expected TPM PCRs, and comparing the
-  calculated PCR values with the physical TPM.  Testing is important to
-  ensure the TPM is initialized prior to IMA.  Failure to validate the
-  IMA measurement list may indicate IMA went into TPM bypass mode, like
-  in this case.
