[PATCH 13/24] x86: Lock down IO port access when the kernel is locked down

From: Matthew Garrett IO port access would permit users to gain access to PCI configuration registers, which in turn (on a lot of hardware) give access to MMIO register space. This would potentially permit root to trigger arbitrary DMA, so lock it down by default.

[PATCH 10/24] hibernate: Disable when the kernel is locked down

From: Josh Boyer There is currently no way to verify the resume image when returning from hibernate. This might compromise the signed modules trust model, so until we can work with signed hibernate images we disable it when the kernel is locked down. Signed-off-by:

[PATCH 07/24] kexec: Disable at runtime if the kernel is locked down

From: Matthew Garrett kexec permits the loading and execution of arbitrary code in ring 0, which is something that lock-down is meant to prevent. It makes sense to disable kexec in this situation. This does not affect kexec_file_load() which can check for a signature

[PATCH 06/24] Add a sysrq option to exit secure boot mode

From: Kyle McMartin Make sysrq+x exit secure boot mode on x86_64, thereby allowing the running kernel image to be modified. This lifts the lockdown. Signed-off-by: Kyle McMartin Signed-off-by: David Howells cc: x...@kernel.org ---

[HMM 10/16] mm/hmm/mirror: helper to snapshot CPU page table v2

This does not use existing page table walker because we want to share same code for our page fault handler. Changes since v1: - Use spinlock instead of rcu synchronized list traversal Signed-off-by: Jérôme Glisse Signed-off-by: Evgeny Baskakov

[HMM 09/16] mm/hmm/mirror: mirror process address space on device with HMM helpers

This is a heterogeneous memory management (HMM) process address space mirroring. In a nutshell this provide an API to mirror process address space on a device. This boils down to keeping CPU and device page table synchronize (we assume that both device and CPU are cache coherent like PCIe device

[PATCH 08/24] Copy secure_boot flag in boot params across kexec reboot

From: Dave Young Kexec reboot in case secure boot being enabled does not keep the secure boot mode in new kernel, so later one can load unsigned kernel via legacy kexec_load. In this state, the system is missing the protections provided by secure boot. Adding a patch to fix

[PATCH 02/24] Add the ability to lock down access to the running kernel image

Provide a single call to allow kernel code to determine whether the system should be locked down, thereby disallowing various accesses that might allow the running kernel image to be changed including the loading of modules that aren't validly signed with a key we recognise, fiddling with MSR

[PATCH 03/24] efi: Lock down the kernel if booted in secure boot mode

UEFI Secure Boot provides a mechanism for ensuring that the firmware will only load signed bootloaders and kernels. Certain use cases may also require that all kernel modules also be signed. Add a configuration option that to lock down the kernel - which includes requiring validly signed modules

[PATCH 05/24] Restrict /dev/mem and /dev/kmem when the kernel is locked down
