Hi Linus, Included in this pull request are bug fixes, code clean up, and new features. Listed below are the main changes. - IMA policy rules can be defined in terms of LSM labels, making the IMA policy dependent on LSM policy label changes, in particular LSM label deletions. The new environment, in which IMA-appraisal is being used, frequently updates the LSM policy and permits LSM label deletions. - Prevent an mmap'ed shared file opened for write from also being mmap'ed execute. In the long term, making this and other similar changes at the VFS layer would be preferable. - The IMA per policy rule template format support is needed for a couple of new/proposed features (eg. kexec boot command line measurement, appended signatures, and VFS provided file hashes). - Other than the "boot-aggregate" record in the IMA measuremeent list, all other measurements are of file data. Measuring and storing the kexec boot command line in the IMA measurement list is the first buffer based measurement included in the measurement list. (Stephen is carrying a patch to address a merge conflict with David's "Keys: Set 4 - Key ACLs for 5.3"). thanks, Mimi The following changes since commit 8cdc23a3d9ec0944000ad43bad588e36afdc38cd: ima: show rules with IMA_INMASK correctly (2019-05-29 23:18:25 -0400) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity.git next-integrity for you to fetch changes up to 650b29dbdf2caf7db27cdc8bfa8fc009b28a6ce3: integrity: Introduce struct evm_xattr (2019-06-30 17:54:41 -0400) ---------------------------------------------------------------- Geert Uytterhoeven (1): integrity: Fix __integrity_init_keyring() section mismatch Janne Karhunen (2): LSM: switch to blocking policy update notifiers ima: use the lsm policy update notifier Matthew Garrett (1): IMA: support for per policy rule template formats Mimi Zohar (2): x86/ima: check EFI SetupMode too ima: prevent a file already mmap'ed write to be mmap'ed execute Nayna Jain (1): x86/ima: fix the Kconfig dependency for IMA_ARCH_POLICY Prakhar Srivastava (3): IMA: Define a new hook to measure the kexec boot command line arguments IMA: Define a new template field buf KEXEC: Call ima_kexec_cmdline to measure the boot command line args Thiago Jung Bauermann (3): ima: Use designated initializers for struct ima_event_data ima: Update MAX_TEMPLATE_NAME_LEN to fit largest reasonable definition integrity: Introduce struct evm_xattr YueHaibing (1): ima: Make arch_policy_entry static Documentation/ABI/testing/ima_policy | 6 +- Documentation/security/IMA-templates.rst | 7 +- arch/x86/kernel/ima_arch.c | 12 ++- drivers/infiniband/core/device.c | 6 +- include/linux/ima.h | 2 + include/linux/security.h | 12 +-- kernel/kexec_file.c | 9 +- security/integrity/digsig.c | 5 +- security/integrity/evm/evm_main.c | 8 +- security/integrity/ima/Kconfig | 3 +- security/integrity/ima/ima.h | 21 +++- security/integrity/ima/ima_api.c | 38 +++++-- security/integrity/ima/ima_appraise.c | 9 +- security/integrity/ima/ima_init.c | 6 +- security/integrity/ima/ima_main.c | 123 ++++++++++++++++++++-- security/integrity/ima/ima_policy.c | 163 +++++++++++++++++++++++++----- security/integrity/ima/ima_template.c | 23 +++-- security/integrity/ima/ima_template_lib.c | 21 ++++ security/integrity/ima/ima_template_lib.h | 4 + security/integrity/integrity.h | 6 ++ security/security.c | 23 +++-- security/selinux/hooks.c | 2 +- security/selinux/selinuxfs.c | 2 +- 23 files changed, 413 insertions(+), 98 deletions(-)
