5e21958c02 efi_selfest: redefine enum efi_test_phase
Setup will always occur before ExitBootServices(). So eliminate
EFI_SETUP_AFTER_BOOTTIME_EXIT. Put the SetVirtualAddressMap() test into a
separate class so that we can execute it last.

f69a2016b6 efi_loader: Add an S-CRTM even for firmware version
TCG PC Client Platform Firmware Profile Spec mandates that an S-CRTM
event for the version identifier using the event type EV_S_CRTM_VERSION
must be measured.

So since we are trying to add more conformance into U-Boot, let's add
the event using U_BOOT_VERSION_STRING, extend PCR[0] accordingly and log
it in the EventLog

4ac6041c3c efi: ESRT creation tests
This commmit exercises the ESRT creation in a EFI selftest.

 A fake FMP, with TEST_ESRT_NUM_ENTRIES FW images, is installed in the
 system leading to the corresponding ESRT entries being populated.
 The ESRT entries are checked against the datastructure used to
 initialize the FMP.

Invocation from the sandbox platform:
add to sandbox_defconfig:
  +CONFIG_CMD_BOOTEFI_SELFTEST=y

 make sandbox_capsule_defconfig all
 ./u-boot -d arch/sandbox/dts/test.dtb

64a8aae15c efi: Add ESRT to the EFI system table
The ESRT is initialised during efi_init_objlist after
efi_initialize_system_table().

The ESRT is recreated from scratch at the following events:
- successful UpdateCapsule;
- FMP instance install.

The code ensures that every ESRT entry has a unique fw_class value.

Limitations:
- The ESRT is not updated if an FMP instance is uninstalled;
- the fields image_type and flags are in the current implementation left
undefined. Setting these values will require a per-platform function
that returns the image_type/flags as a function of the image fw_class.

53f6a5aa86 efi_loader: Replace config option for initrd loading
Up to now we install EFI_LOAD_FILE2_PROTOCOL to load an initrd
unconditionally. Although we correctly return various EFI exit codes
depending on the file status (i.e EFI_NO_MEDIA, EFI_NOT_FOUND etc), the
kernel loader, only falls back to the cmdline interpreted initrd if the
protocol is not installed.

This creates a problem for EFI installers, since they won't be able to
load their own initrd and continue the installation. It also makes the
feature hard to use, since we can either have a single initrd or we have
to recompile u-boot if the filename changes.

So let's introduce a different logic that will decouple the initrd
path from the config option we currently have.
When defining a UEFI BootXXXX we can use the filepathlist and store
a file path pointing to our initrd. Specifically the EFI spec describes:

"The first element of the array is a device path that describes the device
and location of the Image for this load option. Other device paths may
optionally exist in the FilePathList, but their usage is OSV specific"

When the EFI application is launched through the bootmgr, we'll try to
interpret the extra device path. If that points to a file that exists on
our disk, we'll now install the load_file2 and the efi-stub will be able
to use it.

This opens up another path using U-Boot and defines a new boot flow.
A user will be able to control the kernel/initrd pairs without explicit
cmdline args or GRUB.

A following patch introduces a different logic for loading initrd's

Since similar logic can be applied in the future for other system files
(i.e DTBs), let's add some helper functions which will retrieve and
parse file paths stored in EFI variables.

76e8acce12 efi_loader: Add device path related functions for initrd via Boot####
On the following patches we allow for an initrd path to be stored in
Boot#### variables.  Specifically we encode in the FIlePathList[] of
the EFI_LOAD_OPTIONS for each Boot#### variable.

The FilePathList[] array looks like this:
kernel - 0xff - VenMedia(initrd GUID) - initrd1 - 0x01 initrd2 - 0xff
So let's add the relevant functions to concatenate and retrieve a device
path based on a Vendor GUID.

There are two different TPM standards. U-Boot supports both but each has

9c081a7eab efi_loader: limit output length for VenHw, VenMedia
VenHw and VenMedia device path nodes may carry vendor defined data of
arbitrary length. When converting a device path node to text ensure that we
do not overrun our internal buffer.

In our implementation of
EFI_DEVICE_PATH_TO_TEXT_PROTOCOL.ConvertDevicePathToText() we could first
determine the output length and then allocate buffers but that would nearly
double the code size. Therefore keep the preallocated buffers and truncate
excessive device paths instead.

15bbcafab1 efi_loader: fix get_last_capsule()
fix get_last_capsule() leads to writes beyond the stack allocated buffer.
This was indicated when enabling the stack protector.

utf16_utf8_strcpy() only stops copying when reaching '\0'. The current
invocation always writes beyond the end of value[].

The output length of utf16_utf8_strcpy() may be longer than the number of
UTF-16 tokens. E.g has "CapsuleКиев" has 11 UTF-16 tokens but 15 UTF-8
tokens. Hence, using utf16_utf8_strcpy() without checking the input may
lead to further writes beyond value[].

The current invocation of strict_strtoul() reads beyond the end of value[].

A non-hexadecimal value after "Capsule" (e.g. "CapsuleZZZZ") must result in
an error. We cat catch this by checking the return value of strict_strtoul().

A value that is too short after "Capsule" (e.g. "Capsule0") must result in
an error. We must check the string length of value[].

e9adaa75bb smbios: Add more options for the BIOS version string
At present the version string is obtained from PLAIN_VERSION. Some boards
may want to configure this using the device tree, since the build system
can more easily insert things there after U-Boot itself is built. Add this
option to the code.

Also in some cases the version needs to be generated programmatically,
such as when it is stored elsewhere in the ROM and must be read first.
To handle this, keep a pointer around so that it can be updated later.
This works by storing the last string in the context, since it is easier
than passing out a little-used extra parameter.

Provide a function to update the version string.

With the patch the CreateEvent() and CreatedEventEx() services are changed
to check that the notification level is not TPL_APPLICATION.

Reference:
UEFI Specification 2.8 Errata B, table 27 "TPL Restrictions",
"Event Notification Levels"

53e54bf50d efi_loader: Avoid emitting efi_var_buf to .GOT
Atish reports that on RISC-V, accessing the EFI variables causes
a kernel panic. An objdump of the file verifies that, since the
global pointer for efi_var_buf ends up in .GOT section which is
not mapped in virtual address space for Linux.

a80f85138c trace: select TIMER_EARLY to avoid infinite recursion
When tracing functions is enabled this adds calls to
__cyg_profile_func_enter() and __cyg_profile_func_exit() to the traced
functions.

__cyg_profile_func_enter() and __cyg_profile_func_exit() invoke
timer_get_us() to record the entry and exit time.

initr_dm() will make gd->dm_root = NULL and gd->timer = NULL, so
timer_get_us() -> get_ticks() -> dm_timer_init() will lead to an
indefinite recursion.

So select TIMER_EARLY when tracing got enabled.

c0364ce1c6 doc/README.gpt: define partition type GUID for U-Boot environment
When setting aside a GPT partition for holding the U-Boot environment,
having a partition type GUID [1] indicating "Linux filesystem" (as
most tools default to) is somewhat misleading - and there's no other
well-known type GUID that is better suited. So to have a canonical
value to put into the type field, define

    3de21764-95bd-54bd-a5c3-4abe786f38a8

to mean a partition holding a U-Boot environment.

This is a v5 namespace-name GUID [2], generated [3] from a namespace
of "25cbcde0-8642-47c6-a298-1a3a57cd256b" and name "U-Boot
environment".

Should future type GUIDs be defined in the context of U-Boot, it's
sensible to use that same namespace GUID.

Update the only caller accordingly, and get rid of pointless ifdeffery

thus do type-checking, whether or not PARTITION_TYPE_GUID is enabled

With this patch a device-tree file can be loaded. The EFI_DT_FIXUP_PROTOCOL

* apply U-Boot's fix-ups
* let U-Boot make memory reservations as required by the device-tree
* install the new device-tree as configuration table

In a next step this configuration table can be dumped.

A dtbdump.efi session would look like:

4366a2440a crypto: Fix the logic to calculate hash with authattributes set
RFC 2315 Section 9.3 describes the message digesting process. The
digest calculated depends on whether the authenticated attributes are
present. In case of a scenario where the authenticated attributes are
present, the message digest that gets signed and is part of the pkcs7
message is computed from the auth attributes rather than the contents
field.

Check if the auth attributes are present, and if set, use the auth
attributes to compute the hash that would be compared with the
encrypted hash on the pkcs7 message.

47d2b3b9c9 efi_loader: Remove unconditional installation of file2 protocol for initrd
Up to now we install the EFI_LOAD_FILE2_PROTOCOL to load an initrd
unconditionally. Although we correctly return various EFI exit codes
depending on the file status (i.e EFI_NO_MEDIA, EFI_NOT_FOUND etc), the
kernel loader only falls back to the cmdline interpreted initrd if the
protocol is not installed.

This creates a problem for EFI installers, since they won't be able to
load their own initrd and start the installation.

A following patch introduces a different logic where we search for an
initrd path defined in an EFI variable named 'Initrd####'.
If the bootmgr is used to launch the EFI payload, we'll will try to match
the BootCurrent value and find the corresponding initrd
(i.e Boot0000 -> Initrd0000 etc). If the file is found, we'll install
the required protocol which the kernel's efi-stub can use and load our
initrd.

c589132a1d fdt: Use phandle to distinguish DT nodes with same name
While assigning the sequence number to subsystem instances by reading the
aliases property, only DT nodes names are compared and not the complete
path. This causes a problem when there are two DT nodes with same name but
have different paths.

In arch/arm/dts/k3-am65-main.dtsi there are two USB controllers with the
same device tree node name but different path. When aliases are defined for
these USB controllers then fdtdec_get_alias_seq() fails to pick the correct
instance for a given index.

fdt_path_offset() function is slow and this would effect the U-Boot
startup. To avert the time penalty on all boards, apply this extra check
only when required by using a config option.

Fix it by comparing the phandles of DT nodes after the node names match,
under a config option.

bb7e71d33c efi_loader: add firmware management protocol for raw image
In this commit, a very simple firmware management protocol driver
is implemented. It will take a binary image in a capsule file and
apply the data using dfu backend storage drivers via dfu_write_by_alt()
interface.

So "dfu_alt_info" variable should be properly set to specify a device
and location to be updated. Please read README.dfu.

f27c201485 efi_loader: add firmware management protocol for FIT image
In this commit, a very simple firmware management protocol driver
is implemented. It will take a common FIT image firmware in a capsule
file and apply the data using dfu backend storage drivers via
update_fit() interface.

So "dfu_alt_info" variable should be properly set to specify a device
and location to be updated. Please read README.dfu.

Fit image is a common file format for firmware update on U-Boot, and
this protocol works neatly just as a wrapper for one.

8d99026f06 efi_loader: capsule: support firmware update
A capsule tagged with the guid, EFI_FIRMWARE_MANAGEMENT_CAPSULE_ID_GUID,
is handled as a firmware update object.
What efi_update_capsule() basically does is to load any firmware management
protocol (or fmp) drivers contained in a capsule, find out an appropriate
fmp driver and then invoke its set_image() interface against each binary
in a capsule.
In this commit, however, loading drivers is not supported.

The result of applying a capsule is set to be stored in "CapsuleXXXX"
variable, but its implementation is deferred to a fmp driver.

c74cd8bd08 efi_loader: capsule: add capsule_on_disk support
Capsule data can be loaded into the system either via UpdateCapsule
runtime service or files on a file system (of boot device).
The latter case is called "capsules on disk", and actual updates will
take place at the next boot time.

In this commit, we will support capsule on disk mechanism.

Please note that U-Boot itself has no notion of "boot device" and
all the capsule files to be executed will be detected only if they
are located in a specific directory, \EFI\UpdateCapsule, on a device
that is identified as a boot device by "BootXXXX" variables.

c8d0fd5825 efi_loader: Introduce eventlog support for TCG2_PROTOCOL
In the previous patches we only introduced a minimal subset of the
EFI_TCG2_PROTOCOL protocol implementing GetCapability().
So let's continue adding features to it, introducing the
GetEventLog() and HashLogExtendEvent() functions.

In order to do that we first need to construct the eventlog in memory,
specifically in EFI_BOOT_SERVICES_DATA memory and a configuration table
from EFI_ACPI_MEMORY_NVS.
U-Boot won't currently add any events to the log or measure any
components, but will expose the necessary EFI APIs for applications
to do so.

d2cb7a22da x86: Allow putting some tables in the bloblist
At present all tables are placed starting at address f0000 in memory, and
can be up to 64KB in size. If the tables are very large, this may not

Also if the tables point to other tables (such as console log or a ramoops
area) then we must allocate other memory anyway.

The bloblist is a nice place to put these tables since it is contiguous,
which makes it easy to reserve this memory for linux using the 820 tables.

72eda5074b lib: Add getopt
Some commands can get very unweildy if they have too many positional
arguments. Adding options makes them easier to read, remember, and
understand.

This implementation of getopt has been taken from barebox, which has had
option support for quite a while. I have made a few modifications to their
version, such as the removal of opterr in favor of a separate getopt_silent
function. In addition, I have moved all global variables into struct
getopt_context.

The getopt from barebox also re-orders the arguments passed to it so that
non-options are placed last. This allows users to specify options anywhere.
For example, `ls -l foo/ -R` would be re-ordered to `ls -l -R foo/` as
getopt parsed the options. However, this feature conflicts with the const
argv in cmd_tbl->cmd. This was originally added in 54841ab50c ("Make sure
that argv[] argument pointers are not modified."). The reason stated in
that commit is that hush requires argv to stay unmodified. Has this
situation changed? Barebox also uses hush, and does not have this problem.
Perhaps we could use their fix?

I have assigned maintenance of getopt to Simon Glass, as it is currently
only used by the log command. I would also be fine maintaining it.

529441ca89 efi_loader: Disable devices before handing over control
U-Boot Driver Model is supposed to remove devices with either
DM_REMOVE_ACTIVE_DMA or DM_REMOVE_OS_PREPARE flags set, before exiting.
Our bootm command does that by explicitly calling calling
"dm_remove_devices_flags(DM_REMOVE_ACTIVE_ALL);" and we also disable any
USB devices.

The EFI equivalent is doing none of those at the moment. As a result
probing an fTPM driver now renders it unusable in Linux. During our
(*probe) callback we open a session with OP-TEE, which is supposed to
close with our (*remove) callback. Since the (*remove) is never called,
once we boot into Linux and try to probe the device again we are getting
a busy error response. Moreover all uclass (*preremove) functions won't
run.

So let's fix this by mimicking what bootm does and disconnect devices
when efi_exit_boot_services() is called.

42f804fbba efi_loader: fix use after free in receive path
With DM enabled the ethernet code will receive a packet, call
the push method that's set by the EFI network implementation
and then free the packet.  Unfortunately the push methods only
sets a flag that the packet needs to be handled, but the code
that provides the packet to an EFI application runs after the
packet has already been freed.

To rectify this issue, adjust the push method to accept the packet
and store it in a temporary buffer.  The EFI application then gets
the data copied from that buffer.  This way the packet is cached
until is is needed.

The DM Ethernet stack tries to receive 32 packets at once, thus
we better allocate as many buffers as the stack.

4b2be78ab6 time: Fix get_ticks being non-monotonic
get_ticks does not always succeed. Sometimes it can be called before the
timer has been initialized. If it does, it returns a negative errno.
This causes the timer to appear non-monotonic, because the value will
become much smaller after the timer is initialized.

No users of get_ticks which I checked handle errors of this kind. Further,
functions like tick_to_time mangle the result of get_ticks, making it very
unlikely that one could check for an error without suggesting a patch such
as this one.

This patch panics if we ever get an error. There are two cases in which
this can occur. The first is if we couldn't find/probe the timer for some
reason. One reason for this is if the timer is not available so early. This
likely indicates misconfiguration. Another reason is that the timer has an
invalid/missing device tree binding. In this case, panicing is also
correct. The second case covers errors calling get_count. This can only
occur if the timer is missing a get_count function (or on RISC-V, but that
should be fixed soon).

3f8808ebaa rsa: fix retrieving public exponent on big-endian systems
Commit fdf0819afb (rsa: fix alignment issue when getting public
exponent) changed the logic to avoid doing an 8-byte access to a
possibly-not-8-byte-aligned address.

However, using rsa_convert_big_endian is wrong: That function converts
an array of big-endian (32-bit) words with the most significant word
first (aka a BE byte array) to an array of cpu-endian words with the
least significant word first. While the exponent is indeed _stored_ as
a big-endian 64-bit word (two BE words with MSW first), we want to
extract it as a cpu-endian 64 bit word. On a little-endian host,
swapping the words and byte-swapping each 32-bit word works, because
that's the same as byte-swapping the whole 64 bit word. But on a
big-endian host, the fdt32_to_cpu are no-ops, but
rsa_convert_big_endian() still does the word-swapping, breaking
verified boot.

To fix that, while still ensuring we don't do unaligned accesses, add
a little helper that first memcpy's the bytes to a local fdt64_t, then
applies fdt64_to_cpu(). [The name is chosen based on the
[bl]eXX_to_cpup in linux/byteorder/generic.h].

binary calls the EFI API we have to restore it.

e5a31376ac efi_loader: efi_var_mem_notify_exit_boot_services
efi_var_mem_notify_exit_boot_services() is invoked when ExitBootServices()
is called by the UEFI payload.

efi_var_mem_notify_exit_boot_services() should not be defined as
__efi_runtime as it is invoking EFI_ENTRY() and EFI_EXIT() which themselves
are not __efi_runtime.

Fixes: e01aed47d6 ("efi_loader: Enable run-time variable support for tee based variables")

8479333ce7 rsa: crash in br_i32_decode() called from rsa_gen_key_prop()
Fixes problem for unaligned 32bit big-endian access in
lib/rsa/rsa-keyprop.c.

Exchanges br_i32_decode() with get_unaligned_be32().

This will keep the unaligned access for architectures capable and will do
some byte-shift magic for the not so capable ones.
