UEFI specification requires that 5 minutes watchdog timer is
armed before the firmware's boot manager invokes an EFI boot option.
This watchdog timer is updated as follows, according to the
UEFI specification.
1) The EFI Image may reset or disable the watchdog timer as needed.
2) If control is returned to the firmware's boot manager,
the watchdog timer must be disabled.
3) On successful completion of EFI_BOOT_SERVICES.ExitBootServices()
the watchdog timer is disabled.
1) is up to the EFI image, and 3) is already implemented in U-Boot.
This patch implements 2), the watchdog is disabled when control is
returned to U-Boot.
In addition, current implementation arms the EFI watchdog at only
the first "bootefi" invocation. The EFI watchdog must be armed
in every EFI boot option invocation.

Since the efi_update_capsule() represents the UpdateCapsule() runtime
service, it has to handle the capsule flags and update ESRT. However
the capsule-on-disk doesn't need to care about such things.
Thus, the capsule-on-disk should use the efi_capsule_update_firmware()
directly instead of calling efi_update_capsule().
This means the roles of the efi_update_capsule() and capsule-on-disk
are different. We have to keep the efi_update_capsule() for providing
runtime service API at boot time.

The general rule of accepting or rejecting an image is
1. Is the sha256 of the image in dbx
2. Is the image signed with a certificate that's found in db and
not in dbx
3. The image carries a cert which is signed by a cert in db (and
not in dbx) and the image can be verified against the former
4. Is the sha256 of the image in db
For example SHIM is signed by "CN=Microsoft Windows UEFI Driver Publisher",
which is issued by "CN=Microsoft Corporation UEFI CA 2011", which in it's
turn is issued by "CN=Microsoft Corporation Third Party Marketplace Root".
The latter is a self-signed CA certificate and with our current implementation
allows shim to execute if we insert it in db.
However it's the CA cert in the middle of the chain which usually ends up
in the system's db. pkcs7_verify_one() might or might not return the root
certificate for a given chain. But when verifying executables in UEFI, the
trust anchor can be in the middle of the chain, as long as that certificate
is present in db. Currently we only allow this check on self-signed
certificates, so let's remove that check and allow all certs to try a
match an entry in db.
Open questions:
- Does this break any aspect of variable authentication since
efi_signature_verify() is used on those as well?
Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org>
The EFI spec allows for images to carry multiple signatures. Currently
we don't adhere to the verification process for such images.
The spec says:
"Multiple signatures are allowed to exist in the binary's certificate
table (as per PE/COFF Section "Attribute Certificate Table"). Only one
hash or signature is required to be present in db in order to pass
validation, so long as neither the SHA-256 hash of the binary nor any
present signature is reflected in dbx."
With our current implementation signing the image with two certificates
and inserting both of them in db and one of them dbx doesn't always reject
the image. The rejection depends on the order that the image was signed
and the order the certificates are read (and checked) in db.
While at it move the sha256 hash verification outside the signature
checking loop, since it only needs to run once per image and get simplify
the logic for authenticating an unsigned imahe using sha256 hashes.

A mix of signatures and hashes in db doesn't always work as intended.
Currently if the digest algorithm is not explicitly set to sha256 we
stop walking the security database and reject the image.
That's problematic in case we find and try to check a signature before
inspecting the sha256 hash. If the image is unsigned we will reject it
even if the digest matches.
Since we no longer reject the image on unknown algorithms add an explicit
check and reject the image if any other hash algorithm apart from sha256
is detected on dbx.

U-Boot, in some occasions, injects a 'kaslr-seed' property on the /chosen
node. That would be problematic in case we want to measure the DTB we
install in the configuration table, since it would change across reboots.
The Linux kernel EFI-stub completely ignores it and only relies on
EFI_RNG_PROTOCOL for it's own randomness needs (i.e the randomization
of the physical placement of the kernel). In fact it (blindly) overwrites
the existing seed if the protocol is installed. However it still uses it
for randomizing it's virtual placement.
So let's get rid of it in the presence of the RNG protocol.
It's worth noting that TPMs also provide an RNG. So if we tweak our
EFI_RNG_PROTOCOL slightly and install the protocol when a TPM device
is present the 'kaslr-seed' property will always be removed, allowing
us to reliably measure our DTB.

Currently we allow and explicitly check a single shared page with
StandAloneMM. This is dictated by OP-TEE which runs the application.
However there's no way for us dynamically discover the number of pages we
are allowed to use. Since writing big EFI signature list variable
requires more than a page, OP-TEE has bumped the number of shared pages to
four.
Let's remove our explicit check and allow the request to reach OP-TEE even
if it's bigger than what it supports. There's no need to sanitize the
number of pages internally. OP-TEE will fail if we try to write more
than it's allowed. The error will just trigger later on, during the
StMM access.

In order to finish moving this symbol to Kconfig for all platforms, we
need to do a few more things. First, for all platforms that define this
to a function, introduce CONFIG_DYNAMIC_SYS_CLK_FREQ, similar to
CONFIG_DYNAMIC_DDR_CLK_FREQ and populate clock_legacy.h. This entails
also switching all users from CONFIG_SYS_CLK_FREQ to get_board_sys_clk()
and updating a few preprocessor tests.
With that done, all platforms that define a value here can be converted
to Kconfig, and a fall-back of zero is sufficiently safe to use (and
what is used today in cases where code may or may not have this
available). Make sure that code which calls this function includes
<clock_legacy.h> to get the prototype.

When U-Boot is started from another firmware program, not just a prior
phase of U-Boot, special behaviour is typically used. In particular, the
device tree may come from that prior stage.
At present this is sort-of indicated by OF_BOARD, although the
correlation is not 1:1, since that option simply means that the board has
a custom mechanism for obtaining the device tree. For example, sandbox
defines OF_BOARD. Also the board_fdt_blob_setup() function can in fact
make use of the devicetree in U-Boot if it wishes, as used by
dragonboard410c until very recently.
Add an explicit Kconfig for this situation. Update the OF_BOARD option to
more-accurately reflect what it is doing, e.g. for sandbox.
Drop the docs in the README as it is out of date.

It can be confusing to figure out where the devicetree came from. It seems
important enough to warrant a message during boot. Add information about
the number of devices and uclasses too since it is helpful to have some
idea what is going on with driver model.
Report the devicetree source in bdinfo too.
This looks something like this, with > marking the new line.

At present this override function is called even when OF_BOARD is not
enabled. This makes it impossible to disable this feature and in fact
makes the OF_BOARD option useless.
Reinstate its intended purpose, so that it is possible to switch between
the appended devicetree and one provided by the board's custom function.
A follower patch adds warnings for this scenario, but for now we don't
have a Kconfig that definitively tells us that OF_BOARD should be used.
