21 months agoarm64: explicitly disable pointer authentication instructions
Rasmus Villemoes [Mon, 8 Aug 2022 14:12:30 +0000 (16:12 +0200)]
arm64: explicitly disable pointer authentication instructions

The Yocto project builds their aarch64 cross-compiler with the
configure knob --enable-standard-branch-protection, which means that
their gcc behaves as if -mbranch-protection=standard is passed; the
default (lacking that configure knob) is -mbranch-protection=none.

This means that when building U-Boot using the Yocto toolchain, most
functions end up containing paciasp/autiasp/bti instructions. However,
since U-Boot is not an ordinary userspace application, there's no OS
kernel which has set up the required authentication keys, so these
instructions do nothing at all (even on arm64 hardware that does have
the pointer authentication capability). They do however make the image
larger.

It is theoretically possible for U-Boot to make use of the pointer
authentication protection - cf. the linux kernel's
CONFIG_ARM64_PTR_AUTH_KERNEL - but it is far from trivial, and it's
hard to see just what threat model it would protect against in a
bootloader context. Regardless, we certainly have none of the required
infrastructure now, so explicitly pass -mbranch-protection=none to
ensure those useless instructions do not get emitted.

For a toolchain not configured with
--enable-standard-branch-protection, this changes nothing. For the
Yocto toolchain, this reduces the size of both SPL and U-Boot proper
by about 3% for my imx8mp target.

If you don't have a Yocto toolchain, the effect can easily be
reproduced by applying this patch and changing =none to =standard.

the i.MX6, i.MX8 and stm32mp1 based boards.

All pre-existing implementations follow the same logic:

(1) Check if ethaddr is already set in the environment
(2) If not, try to get it from a board specific location (e.g. fuse)
(3) If not, try to get it from eeprom

After this commit, (1) and (3) are implemented as common functions,
ready to be used by board specific files.

To quote Simon:
This adds the concept of a VBE method to U-Boot, along with an
implementation of the 'VBE simple' method, basically a simple way of
updating firmware in MMC from userspace and monitoring it from U-Boot.

VBE simple is implemented in fwupd. U-Boot's role is to set up the
device tree with the required firmware-update properties and provide the
developer with information about the current VBE state. To that end this
series includes a new 'vbe' command that allows VBE methods to be listed
and examined.

As part of this work, support for doing FDT fixups via the event interface
is provided, along with the ability to write to the device tree via the
ofnode interface.

Another (significant) change is that bootmeths now have a 'global' flag,
to allow the implementation of EFI bootmgr (and VBE) to be cleaned up.
The 'system' bootdev is no-longer needed and these bootmeths are scanned
first.

Further work is needed to pull everything together, but this is a step
along the way.
