Usually, that function expects EFI_BOOT_SERVICES_DATA memory descriptors but the above case is for the MOKvar table which is allocated in the EFI shim as runtime services. That lead to a fix changing the allocation of that table to boot services. However, that fix broke booting SEV guests with that shim leading to this kernel fix 8d651ee9c71b ("x86/ioremap: Map EFI-reserved memory as encrypted for SEV") which extended the ioremap hint to map reserved EFI boot services as decrypted too. However, all that wasn't needed, IMO, because that error message in efi_arch_mem_reserve() was innocuous in this case - if the MOKvar table is not in boot services, then it doesn't need to be reserved in the first place because it is, well, in runtime services which *should* be reserved anyway. So do that reservation for the MOKvar table only if it is allocated in boot services data. I couldn't find any requirement about where that table should be allocated in, unlike the ESRT which allocation is mandated to be done in boot services data by the UEFI spec.

However, nobody seems to agree how to flag these regions as reserved, and (for example) EFI only publishes its reservations in /proc/iomem for the benefit of the traditional, userspace based kexec tool. On arm64 platforms with GICv3, this can result in the payload being placed at the location of the LPI tables. Shock, horror! Let's augment the EFI reservation code with a memblock_reserve() call, protecting our dear tables from the secondary kernel invasion.

Any Hypervisor could use the FFA interfaces to enable communication between VMs it manages. The Hypervisor a.k.a Partition managers in FFA terminology can assign system resources(Memory regions, Devices, CPU cycles) to the partitions and manage isolation amongst them. This is the initial and minimal support for the FFA interface to enable communication between secure partitions and the normal world OS. * tag 'arm-ffa-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_ffa: Add support for MEM_* interfaces firmware: arm_ffa: Setup in-kernel users of FFA partitions firmware: arm_ffa: Add support for SMCCC as transport to FFA driver firmware: arm_ffa: Add initial Arm FFA driver support firmware: arm_ffa: Add initial FFA bus support for device enumeration arm64: smccc: Add support for SMCCCv1.2 extended input/output registers Link: https://lore.kernel.org/r/20210601095838.GA838783@bogus Signed-off-by: Olof Johansson <olof@lixom.net>

| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Arm FF for Armv8-A specification has concept of endpoints or partitions. In the Normal world, a partition could be a VM when the Virtualization extension is enabled or the kernel itself. In order to handle multiple partitions, we can create a FFA device for each such partition on a dedicated FFA bus. Similarly, different drivers requiring FFA transport can be registered on the same bus. We can match the device and drivers using UUID. This is mostly for the in-kernel users with FFA drivers.

However once the synchronous part completes the transport layer waits for the delayed response which will be processed using the same xfer descriptor initially allocated. Since synchronous response received at the end of the xfer will shrink the Rx buffer length to the effective payload response length, it needs to be reset again. Raise the Rx buffer length again to max_msg_sz before fetching the delayed response to ensure full response is read correctly from the shared memory.
