 I thought about it again and felt it might not be correct to return
 reset_ctl always. The reset control is optional only if the consumer
 node doesn't have populated reset properties.

 If we always return valid reset_ctl possibly with it's dev member
 initialized or not initialized, it would not be possible to tell it's
 not initialized because of the absence of reset property or due to some
 other valid error.

hmm, I pointed to the wrong function from clk-uclass. The below clk
function is similar to our reset usecase

struct clk *devm_clk_get_optional(struct udevice *dev, const char *id)
{
struct clk *clk = devm_clk_get(dev, id);

if (PTR_ERR(clk) == -ENODATA)
return NULL;

return clk;
}

For this case, clk_valid() works because it checks for "clk" pointer and
for ENODATA case (get_optional), the client will have clk = NULL and
pass NULL to all the clock APIs.

IIUC, you don't prefer returning NULL to client on ENODATA (or any other
error)? And that's why unlike devm_clk_get_optional() which returns NULL
on ENODATA, $patch directly returns devm_reset_control_get().

So for reset it could return
1) valid reset_ctl pointer with dev initialized
2) -ENOMEM (if allocation of reset_ctl itself fails)
3) -ENODATA (if reset-names is not populated in DT)
4) -ENOENT/-EINVAL (for other DT errors)

clk-uclass has a separate class of APIs that ends with _nodev(). Here
the client allocates memory for clk and let clk framework populate
clk->dev. For the other APIs where clk framework itself returns clk
pointer, there is no case where clk framework returns a valid clk
pointer but without clk->dev initialized (the second case is what we
deal in reset).

Since reset at this point doesn't deal with _nodev(), the latter case
above for clk is what should be considered (i.e reset returns valid
reset_ctrl pointer with dev initialized or return an error value).

So again coming back to the return values mentioned above [ 1) valid
reset, 2) -ENOMEM, 3) -ENODATA, 4) -ENOENT/-EINVAL ].

For get_optional()
  1) Should we return NULL on -ENODATA (similar to devm_clk_get_optional())?
  2) If we

Let me make clear: "a single binary or 2 binaries" is not
an implementation detail, but it's a matter of user's (, distro's
or whoever wants to provide a capsule) policy.

If signing feature is enabled in mkeficapsule, you can create
both a signed capsule and an unsigned capsule.
And yet, some users may totally had no need to authentication
for firmware update using UEFI interfaces on their systems.
For them, signing should be able to be disabled.

I don't get your point.
As far as we maintain CONFIG_(HOST_)_EFI_CAPSULE_AUTHENTICATE,
we can and should guarantee the compatibility.

I don't get you point neither.

Again, (major) distros are ones of users.
There may be bunch of users who may build/maintain their systems
on their way and not expect any authentication.

Having said that,
coincidentally there is happening a similar discussion
about building host tools and host-specific configs among Simon, Tom
and Alex[1].
(The background for the discussion is a bit different though.)

I'd like to see and follow the direction to be agreed there.

So far, we have been discussing whether CONFIG_EFI_CAPSULE_AUTHENTICATE
(or "host" version like CONFIG_HOST_EFI_CAPSULE_AUTHENITATE)
be honored in mkeficapsule.c or not.

There exist lots of "hostprogs-$(CONFIG_...)" targets.
I think that this is a common practice in U-Boot.

Re: [PATCH] Revert "riscv: cpu: fu740: clear feature disable CSR"

Hi Bin,

Thanks, I'll include that revert. Just traced back the git log. My original
patch is based on fu740. I guess it was merged to fu540 since fu740 series
wasn't present yet.

Hi Rick,

Not sure whether you'll pick fu740 series soon or if any parts need more
revisement. Do you prefer that I append both this revert and "disable CSR"
patch to fu740 patch series? If so, I will create v9 patch and
include these 2 patches.

Or if you prefer to keep them separate from fu740 series, we can wait for
fu740 patch merge and I'll create a separate patch for this revert
and CSR disable.

What do you think? Many thanks.

[PATCH v3 1/1] clk: zynq: Add clock wizard driver

[zhengxun]

The Clocking Wizard IP supports clock circuits customized
to your clocking requirements. The wizard support for
dynamically reconfiguring the clocking primitives for
Multiply, Divide, Phase Shift/Offset, or Duty Cycle.

Limited by uboot clk uclass without set_phase API, this
patch only provides set_rate to modify the frequency.

In my case (I've tested it on the DeveloperBox), the key is embedded in
the U-Boot's control device tree.

However, I agreed this point. If we use the public key in the device
tree, it must be loaded as a part of U-Boot itself, and must not overwritten
by the user given fdt.

Re: [PATCH 2/4] tools: mkeficapsule: remove device-tree related operationy

[AKASHI Takahiro]

Heinrich,

You are discussing two different issues:
1. if we should remove "-K/-D" options from mkeficapsule
2. if it is safe or not to store a key in device tree

It makes the discussion in this thread confusing.

OK, you meant U-Boot's fdt command.

What I meant by "control device tree" is the feature
provided by OF_CONTROL+OF_EMBED with Sughosh's patch[1]
which is also a prerequisite for my patch 

[PATCH v2 16/16] RFC: clk: Return error code from clk_set_default_get_by_id()

[Simon Glass]

At present the error code is never returned. Fix it.

With this change, the following error is produced:

   test/dm/clk.c:50, dm_test_clk():
  0 == uclass_get_device_by_name(UCLASS_CLK, "clk-sbox", _clk):
  Expected 0x0 (0), got 0xfffe (-2)
   Test: dm_test_clk: clk.c (flat tree)
   test/dm/clk.c:50, dm_test_clk():
  0 == uclass_get_device_by_name(UCLASS_CLK, "clk-sbox", _clk):
  Expected 0x0 (0), got 0xfffe (-2)

Also this causes a crash in sandbox:

   Test: dm_test_clk: clk.c

   Program received signal SIGSEGV, Segmentation fault.
   sandbox_clk_query_enable (dev=, id=id@entry=0)
   at drivers/clk/clk_sandbox.c:164
   164  return priv->enabled[id];
   (gdb) q

A few other tests fail also, as marked.

Signed-off-by: Simon Glass 
Reported-by: Coverity (CID: 312946)

Changes in v2:
- Disable dm_test_simple_pm_bus() also, since it fails
- Drop patch: sandbox: Indicate NULL-pointer access in 'sigsegv' command

[PATCH v2 15/16] clk: Detect failure to set defaults

[Simon Glass]

When the default clocks cannot be set, the clock is silently probed and
the error is ignored. This is incorrect, since having the clocks at the
correct speed may be important for operation of the system.

Fix it by checking the return code.

[PATCH v2 04/16] tools: Avoid showing return value of clock_gettime()

This value is either 0 for success or -1 for error. Coverity reports that
"ret" is passed to a parameter that cannot be negative, pointing to the
condition 'if (ret < 0)'.

Adjust it to just check for non-zero and avoid showing -1 in the error
message, which is pointless. Perhaps these changes will molify Coverity.

[PATCH 0/3] Fix 'reset' for TI K3 AM64x and J721E/J7200 boards

[Suman Anna]

Hi Lokesh,

The following patches fix the 'reset' command functionality for various
TI K3 SoCs. Patches are based on the latest master that includes the
AM64x board support, commit ea184cbff99e ("Merge tag 'ti-v2021.07-rc3'
of https://source.denx.de/u-boot/custodians/u-boot-ti;).

The first patch is needed for J721E/J7200 SoCs with newer System
Firmwares (anything newer that 2020.04 SYSFW) and is backward
compatible. Without this, the 'reset' command throws the following
warnings,
  => reset
  resetting ...
  ti-sci-sysreset sysreset-controller: ti_sci_sysreset_request: reboot_device 
failed (-19)
  ti-sci-sysreset sysreset-controller: ti_sci_sysreset_request: reboot_device 
failed (-19)
  ti-sci-sysreset sysreset-controller: ti_sci_sysreset_request: reboot_device 
failed (-19)
  System reset not supported on this platform
  ### ERROR ### Please RESET the board ###

The second and third patches add the required ti-sci sysreset nodes
for the AM64x EVM and SK boards respectively. The required SYSRESET
and SYSRESET_TI_SCI configs are already enabled in the
am64x_evm_a53_defconfig.

regards
Suman

[PATCH v8 2/3] efi_loader: expose efi_image_parse() even if UEFI Secure Boot is disabled

[Masahisa Kojima]

This is preparation for PE/COFF measurement support.
PE/COFF image hash calculation is same in both
UEFI Secure Boot image verification and measurement in
measured boot. PE/COFF image parsing functions are
gathered into efi_image_loader.c, and exposed even if
UEFI Secure Boot is not enabled.

This commit also adds the EFI_SIGNATURE_SUPPORT option
to decide if efi_signature.c shall be compiled.

Changes in v8:
- remove superfluous "depends on" in Kconfig

(no changes since v4)

Changes in v4:
- revert #ifdef instead of using "if (!IS_ENABLED())" statement,
  not to rely on the compiler optimization.

Changes in v3:
- hide EFI_SIGNATURE_SUPPORT option

Changes in v2:
- Remove all #ifdef from efi_image_loader.c and efi_signature.c
- Add EFI_SIGNATURE_SUPPORT option
- Explicitly include 
- Gather PE/COFF parsing functions into efi_image_loader.c
- Move efi_guid_t efi_guid_image_security_database in efi_var_common.c

[PATCH v8 1/3] lib: introduce HASH_CALCULATE option

[Masahisa Kojima]

Build error occurs when CONFIG_EFI_SECURE_BOOT or
CONFIG_EFI_CAPSULE_AUTHENTICATE is enabled,
because hash-checksum.c is not compiled.

Since hash_calculate() implemented in hash-checksum.c can be
commonly used aside from FIT image signature verification,
this commit itroduces HASH_CALCULATE option to decide
if hash-checksum.c shall be compiled.

(no changes since v7)

Changes in v7:
- newly introduce HASH_CALCULATE option

Changes in v6:
- update lib/Makefile to compile hash-checksum.c, instead of
  selecting FIT_SIGNATURE in secure boot and capsule authentication.

Changes in v5:
- Missing option for EFI_TCG2_PROTOROL already added in different commit.
  This commit adds FIT_SIGNATURE only.

Changes in v4:
- newly added in this patch series, due to rebasing
  the base code.

[PATCH] arm: dts: k3-j721e: Fix up MAIN R5FSS cluster mode back to Split-mode

[Suman Anna]

The default U-Boot environment variables and design are all set up for
both the MAIN R5FSS clusters to be in Split-mode. This is the setting
in v2021.01 U-Boot and the dt nodes are synched with the kernel binding
property names in commit 468ec2f3ef8f ("remoteproc: k3_r5: Sync to
upstreamed kernel DT property names") merged in v2021.04-rc2.

The modes for both the clusters got switched back to LockStep mode by
mistake in commit 70e167495ab2 ("arm: dts: k3-j721e: Sync Linux v5.11-rc6
dts into U-Boot") also in v2021.04-rc2. This throws the following warning
messages when early-booting the cores using default env variables,

  k3_r5f_rproc r5f@5d0: Invalid op: Trying to start secondary core 7 in 
lockstep mode
  Load Remote Processor 3 with data@addr=0x8200 98484 bytes: Failed!
  k3_r5f_rproc r5f@5f0: Invalid op: Trying to start secondary core 9 in 
lockstep mode
  Load Remote Processor 5 with data@addr=0x8200 98484 bytes: Failed!

Fix this by switching back both the clusters to the expected Split-mode.

We must just be talking at cross-purposes. The function you show above
returns an error code, so there is no need for the caller to check clk
if an error is returned. For the -ENODATA case, note that
clk_get_by_name_nodev() sets clk->dev to NULL, thus ensuring that
clk_valid() works as expected.

But all of your patches are about a function that returns a pointer,
which is a different thing

I'm a bit lost at this point...will look at what you send.

Yes, that is a good point. Perhaps I was not mad when I wrote that.

Let's fix it then. The patch makes all the hashing algorithms work the
same, which seems right to me. If we come to converting this to a
linker list, which we should, then it will be easier with this patch
applied than not.

OK. It's up to Tom what he wants to do. But how about sending a patch
to do what you want, instead?

I did consider simply defining CONFIG_IS_ENABLED() to true for the
host, but rejected that because I worried it would break down at some
point. Examples I can think of at the moment:

- conflicting or alternative options (OF_LIVE, OF_HOST_FILE, OF_SEPARATE)
- code that is not actually wanted on the host (WATCHDOG,

[PATCH v4] mmc: Update environment variable with active partition

[Reuben Dowle]

This patch allows uboot scripts make choices about where to boot from based
on the active mmc boot partition. This allows having two copies of kernel,
filesystems etc, and choosing which to boot from based off of the active
bootloader partition.

It is described (quite explicitly) in the current devicetree
specification draft.

I suspect Atish is asking because of the issue I opened for opensbi:

  https://github.com/riscv/opensbi/issues/210

On many RISC-V platforms, opensbi runs in "machine mode" (somewhat
equivalent to EL3 on ARMv8) and allocates some memory for itself.  It
sets up protections for this memory such that "supervisor mode"
(somewhat equivalent to EL1 on ARMv8) can't access this memory.

Older versions of opensbi marked this memory area as "no-map",
resulting in that memory area being marked as EfiReservedMemoryType,
and evrything is fine.

However, according to reserved-memory.txt, "no-map" means the the area
isn't supposed to be mapped by the OS at all.  That is deemed
undesirable since it prevents the OS from using a large 2MB or 1G page
table entry to map the memory range that happens to include the memory
reserved for opensbi.  That is sub-optimal as it means the OS has to
allocated more levels of page tables for this memory block and has to
use 4K pages which will increase TLB pressure.  So newer versions of
opensbi dropped the "no-map" property resulting in the area being
marked as EfiBootServicesData.  But that is obviously wrong since the
OS can't actually access that memory range.

Now somewhat by accident the Linux kernel didn't actually attempt to
use this memory area so the issue wasn't noticed.  But we're working
on OpenBSD/riscv64 and when I added code to use the EFI memory map the
OpenBSD kernel tried to use that inaccessable memory, which obviously
didn't end well.

I suspect differences between the ARMv8 and RISC-V architecture are at
play here.  On ARMv8 "secure" memory areas like this are not supposed
to be mapped as speculative access might trigger a fault.  But on
RISC-V mapping a "protected" memory area is fine as long as you don't
try to actually access it.

So the question really is how opensbi can express that a certain
memory area is reserved (and should end up as EfiReservedMemoryType in
the EFI memory map) but that it is ok to map it.  Possible solution
include:

* Change the interpretation of the "no-map" property for RISC-V such
  that it is clear that the region in question can be mapped but can
  not be accessed.  This only makes sense if the RISC-V architecture
  guarantees that creating a mapping for physical memory will never
  cause problems even if those areas can't be accessed.

* Invent a new property that conveys the desired semantics.

* Always flag memory ranges under /reserved-memory as
  EfiReserbedMemoryType unless that memory range is marked as
  "reusable".

Cheers,

Mark

You are right, it's only fixed in NXP fork, with kernel driver modification. We
prefer the current u-boot bch geometry, so I will send out a kernel patch to

[PATCH] dm: core: fix no null pointer detection in ofnode_get_addr_size_index()

[chenguanqiao]

From: Chen Guanqiao 

Fixed a defect of a null pointer being discovered by Coverity Scan:
   CID 331544:  Null pointer dereferences  (REVERSE_INULL)
   Null-checking "size" suggests that it may be null, but it has already been 
dereferenced on all paths leading to the check.

In the mail-thread starting a

[PATCH 1/1] EBBR: GetMemoryMap(), handling of no-map DT property
https://lists.linaro.org/pipermail/boot-architecture/2020-September/001389.html

the issue has been discussed. The conclusion was that we should not
change the current behavior.



Digging some old threads :)

The merged version of the patch marks any reserved memory as
EFI_BOOT_SERVICES_DATA.
AFAIK, these memory regions will be available after ExitBootservice.
If the operating system chooses to
map these region and access them, it violates the purpose of the
reserved memory region specified by the firmware.

Did I miss something ?


The no-map property is neither described in the EBBR nor in the
Devicetree specification v0.3 but only in Linux' reserved-memory.txt.

In
https://lists.linaro.org/pipermail/boot-architecture/2020-September/001418.html
Ard requested that no-map memory shall be marked EfiReservedMemory
because Linux will not map EfiReservedMemory, see Linux function
is_usable_memory().

All reserved memory that is not marked as no-map shall be mapped by
Linux. It may for instance serve as DMA pool or as video memory. Or it
may even be reusable. See reserved-memory.txt.

Only drivers will access their own reserved memory if the region is not
marked as reusable.

BTW, IMHO, if u-boot.bin can not find the ESL in the device tree,

In this case the capsule should be rejected (if
CONFIG_EFI_CAPSULE_AUTHENTICATE=y).


That's basically right.
But as I mentioned in my comment against Sughosh's patch,
the authentication process will be enforced only if the capsule has
an attribute, IMAGE_ATTRIBUTE_AUTHENTICATION_REQUIRED.



That would be a security desaster.


The requirement that I mentioned above is clearly described
in UEFI specification.
If you think that it is a disaster, please discuss the topic
in UEFI Forum first.


I confirmed UEFI specification, version 2.7, Section.23.1
the last of EFI_FIRMWARE_MANAGEMENT_PROTOCOL.GetImageInfo()

-
If IMAGE_ATTRIBUTE_AUTHENTICATION_REQUIRED is supported and clear, then
authentication is not required to perform the firmware image operations.
-


IMAGE_ATTRIBUTE_AUTHENTICATION_REQUIRED bit is a property of the FMP driver.

Best regards

Heinrich



Oh, this is really crazy because deciding whether to authenticate the
suspicious
package or not, depends on whether the package said "please
authenticate me" or not. :D

Anyway, since this behavior follows the specification, it should be
kept by default,
but also IMHO, there should be a CONFIG option to enforce capsule
authentication always.

Thank you,

As we discussed, "-K" and "-D" options have nothing to do with

$ dtc -@ -I dts -O dtb -o signature.dtbo signature.dts
$ fdtoverlay -i test.dtb -o test_sig.dtb -v signature.dtbo

So just remove this feature.
(Effectively revert the commit 322c813f4bec ("mkeficapsule: Add support
for embedding public key in a dtb").)

The same feature is implemented by a shell script (tools/fdtsig.sh).



The only reason I can see to keep this, is if mkeficapsule gets included
intro distro packages in the future.  That would make end users life a bit
easier, since they would need a single binary to create the whole
CapsuleUpdate sequence.


Hmm, I think it is better to write a manpage of mkeficapsule which
also describes
how to embed the key into dtb as in the above example if it is so short.
Or, distros can package the above shell script with mkeficapsule.

Embedding a key and signing a capsule are different operations but
using the same tool may confuse users (at least me).


Sure fair enough.  I am merely pointing out we need a way to explain all of
those to users.


This is currently our only documentation:

https://u-boot.readthedocs.io/en/latest/board/emulation/qemu_capsule_update.html?highlight=mkeficapsule


As I mentioned several times (and TODO in the cover letter),
this text must be reviewed, revised and generalized
as a platform-independent document.
It contains a couple of errors.


For mkimage we have a man-page ./doc/mkimage.1 that is packaged with
Debians u-boot-tools package. Please, provide a similar man-page as
./doc/mkeficapsule.1.


So after all do you agree to removing "-K/-D"?


I see no need to replicate in U-Boot what is already in the device tree
compiler package.


This is another reason that we should remove Sughosh's change.


In the current workflow the fdt command is used to load the public key.
This is insecure and not usable for production.


I totally disagree.
Why is using fdt command (what do you mean by fdt command, dtc/fdtoverlay?)
insecure?


A user can load an insecure capsule.

The fdt command is in /cmd/fdt.c and you are referring to it in
board/emulation/qemu_capsule_update.rst.




The public key used to verify the capsule must be built into the U-Boot
binary. This will supplant the -K and -D options.


I don't get your point. You don't understand my code.

Even with Sughosh's original patch, the public key (as I said,
it is not a public key but a X509 certificate in ESL format) is
embedded in the U-Boot's "control device tree".


No, the ESL file it is not built into U-Boot's control device tree.

A user is loading it and updating the control device tree.

You shouldn't trust anything a user has loaded. You need at least the
public key of the root CA built somewhere into U-Boot.

The 'fdt resize' command may overwrite code. This is not what you want
to do with the control device tree.

If CONFIG_OF_LIVE=y, the active device tree is not at $fdtcontroladdr
but in a hierarchical structure. You cannot update it via the fdt command.



Even after applying my patch, this is true.

Or are you insisting that the key should not be in the device tree?


The public key of the root CA must not be in a place where it can be
changed by a user while the device is in deployed mode.

The device-tree based design is a good feasibility study but not
suitable for production.

My point is that if you are changing the logic of reset_request(), you
should add a test for it and you need to update the docs.

Do you have someone at TI that can work through this with you? I am
not the maintainer of this subsystem, nor the expert here, but I feel
it could use a review with someone else as well, to really nut out all
the issues once and for all.

Based on what was discussed in the thread waht I think would make more
sense is:
- Build u-boot and use the script Akashi sent to inject the certificate. 
  Whether we create a single binary (always signed if a config option is
  there) or 2 binaries (1 signed. 1 unsigned) is an implemetation detail
  and I am fine with either.
- Use mkefi capsule to create the final capsule

So that's the point exactly. Building the tool is completely disjoint from
building a u-boot binary.   Also you usually start adding config options to
an app, when it starts getting to big and you want discrete functionality. 
I don't see any reason for making a simple tool, which is supposed to do 2
things (create/sign), require config options and more over config options
*for U-Boot*. I also think it's extremely unlikely to get any working distro 
without libssl.

That's basically right.

the authentication process will be enforced only if the capsule has
an attribute, IMAGE_ATTRIBUTE_AUTHENTICATION_REQUIRED.



That would be a security desaster.


The requirement that I mentioned above is clearly described

If IMAGE_ATTRIBUTE_AUTHENTICATION_REQUIRED is supported and clear, then
authentication is not required to perform the firmware image operations.

Thank you for citing this.


Oh, this is really crazy because deciding whether to authenticate the
suspicious
package or not, depends on whether the package said "please
authenticate me" or not. :D


Well, the attributes can been fetched with GetInfo API, but
how it is managed depends on the implementation of FMP drivers.

As I proposed somewhere else, those attributes should be
maintained in a separate place (maybe as part of system's policy),
presumably ESRT or platform-specific internal database?


FWIW I personally don't think we should even have a config option. But even
if we did it certainly must not be dictated by a hardware config.

When you install distro packages you accept whatever dependencies the
package has. mkeficapsule is a capsule creation and signing tool.  I don't
see any reason for keeping the creation and signing apart.


My question is, since the U-Boot binary is heavily dependent on the target
platform, can we split the u-boot.bin creation (may include embedding keys)
and the capsule file creation (including signing)?


Building U-Boot and creating a capsule are totally separate. Maybe you
get the first capsule years after you buy your board. But this should
not stop us from building mkeficapsule when building U-Boot.

If you want to build tools only, you can do so with 'make tools'. The
tools target must include mkeficapsule irrespective of configuration.

This line in tools/Makefile must be corrected:

-hostprogs-$(CONFIG_EFI_HAVE_CAPSULE_SUPPORT) += mkeficapsule
+hostprogs-y += mkeficapsule

This option also doesn't make sense.This seems to do what 'mkimage -l'
already supports.


Are you sure you have looked at the goal of the CONFIG_IS_ENABLED()
changes? This is here purely to avoid #ifdefs in the share code.


On the one hand, we have the cosmetic inconvenience caused by #ifdefs.
On the other hand we have the config system. To most users, the config
system is likely more visible, while it's mostly developers who will
ever see the ifdefs.

Therefore, in order to get the developer convenience of less ifdefs, we
have to sacrifice user convenience by cloberring the Kconfig options. I
think this is back-to-front.


These Kconfig options are not visible to users. They cannot be updated
in defconfig, nor in 'make menuconfig', etc. They are purely there for
the build system.



Can we reduce the host config count to just SLL/NOSSL?


The point here is that the code has a special case for host builds,
and this is a means to remove that special case and make the code
easier to maintain and follow.


I understand where you're coming from. Without these changes, the code
knows what it should and should not do, correct? My argument is that if
the code has the logic to do the correct thing, that logic should not be
split with the config system.

I agree with the goal of reducing clutter in the source code. I disagree
with this specific course of fixing it. Instead, I propose a single
kconfig for host tools for SSL on/off.

The disadvantage of my proposal is that we have to refactor the common
code in a way consistent with the goals, instead of just changing some
#ifdefs to if(CONFIG_IS_ENABLED()). I admit that, off the top of my
head, I don't have a detailed plan on how to achieve this.


You are mostly describing the status quo, so far as I understand it.
The problem is with the code that is built for both boards and tools.
For boards, we want this code to be compiled conditionally, depending
on what options are enabled. For tools, we want the code to be
compiled unconditionally.

I can think of only three ways to do this:

- status quo (add #ifdefs USE_HOSTCC wherever we need to)
- my series (make use of hidden Kconfig options to avoid that)
- put every single feature and associated lines of code in separate
files and compile them conditionally for boards, but always for tools

I believe the last option is actually impossible, or at least
impractical. It would cause an explosion of source files to deal with
all the various combinations, and would be quite painful to maintain
also.


I don't think the status quo is such a terrible solution, so I am 
looking at the aspects that can benefit from improvement. Hence why it 
may appear I am talking about the status quo.


Let's assume CONFIG_IS_ENABLED() returns true on host builds, and for 
those cases where you need to know if IS_HOST_BUILD(), there's a macro 
for that. You have the oddball case that uses a CONFIG_ value that's 
only defined on the target, and those you would have to split according 
to your option #3.


I don't think the above is as dire an explosion in source files as it seems.

Another point of contention is checksum_algos and crypto_algos arrays 
image-sig.c. On the target side, these should be in .u-boot-list. Status 
quo is the definition of rsa_verify is hidden behind #if macros, which 
just pushes the complexity out into the rsa.h headers.


The two ideas here are CONFIG_IS_ENABLED() returns true for host code, 
and image-sig.c is split bwtween host and target versions, the target 
version making use of .uboot-list. Using these as the starting points, I 
think we can get to a much better solution

My question is, since the U-Boot binary is heavily dependent on the target
platform, can we split the u-boot.bin creation (may include embedding keys)
and the capsule file creation (including signing)?

This is all a mess. We should not use weak functions IMO, but

instead

have a driver interface, like we do with filesystems.

Part of the challenge is the need to keep code size small for
platforms that only need one algorithm.


If a function is not referenced, the linker will eliminate it. But

with

a driver interface every function in the interface is referenced.


Indeed, but we can still have an option for enabling the progressive
interface. My point is that the implementation (software or hardware)
should use a driver.

Anyway that should not stop us from reverting a problematic patch. We can work 
on refactoring afterwards.


Well the patch was applied because tests passed. We should be careful
about reverting a patch due to problems it causes in the future.


The code compiled because SHA384 and SHA512 were not used together with
CONFIG_SHA_HW_ACCEL=y. But we need these functions to implement the TCG2
protocol on boards with TPMv2.

Gitlab CI had no issues with reverting the patch.

Hm, can you send me the U-Boot output?

Can you also try adding :0? I noticed it in my partition aliases:

"fastboot_aliases=setenv fastboot_partition_alias_user ${mmcdev}.0:0; " 
\
"setenv fastboot_partition_alias_boot0 ${mmcdev}.1:0; " \
"setenv fastboot_partition_alias_boot1 ${mmcdev}.2:0;\0" \

Re: [PATCH] Fix flash and erase of EMMC_BOOT2 with fastboot

Hi,

Have you considered trying to flash using e.g.

flashboot flash 0.1 foo.img

instead of

fastboot flash boot0

? I would like to remove these MMC_BOOT2 options but I haven't gotten around to 
it.

Changes in v4:
- newly added in this patch series, due to rebasing

Otherwise we cannot correctly fill SMBIOS tables. This shows up in

This sounds like a bug in the smbios-table code. For sandbox it should
perhaps use addresses instead of pointers.

I think that code (that I unfortunately wrote) was an expeditious way
of getting it running, but is not correct.


The field you are filling is only 32bit wide. I wonder how that table is meant 
to work on systems where the lowest memory address is above 4 GiB. Such ARMv8 
systems exist.


map_to_sysmem() will give you a 32-bit wide address. Yes SMBIOS is
legacy and designed for 4GB.


I know map_to_sysmem(). But you wrote in lib/smbios.c:487:

/*
 * We must use a pointer here so things work correctly on sandbox. The
 * user of this table is not aware of the mapping of addresses to
 * sandbox's DRAM buffer.
 */

For testing you could start a binary with command 'bootefi' or 'booti'
and that binary would analyze the table. So yes, your comment holds true
and you must not use map_to_sysmem() here.

[PATCH v7 2/3] efi_loader: expose efi_image_parse() even if UEFI Secure Boot is disabled

[Masahisa Kojima]

This is preparation for PE/COFF measurement support.
PE/COFF image hash calculation is same in both
UEFI Secure Boot image verification and measurement in
measured boot. PE/COFF image parsing functions are
gathered into efi_image_loader.c, and exposed even if
UEFI Secure Boot is not enabled.

This commit also adds the EFI_SIGNATURE_SUPPORT option
to decide if efi_signature.c shall be compiled.

Signed-off-by: Masahisa Kojima

(no changes since v4)

Changes in v4:
- revert #ifdef instead of using "if (!IS_ENABLED())" statement,
  not to rely on the compiler optimization.

Changes in v3:
- hide EFI_SIGNATURE_SUPPORT option

Changes in v2:
- Remove all #ifdef from efi_image_loader.c and efi_signature.c
- Add EFI_SIGNATURE_SUPPORT option
- Explicitly include 
- Gather PE/COFF parsing functions into efi_image_loader.c
- Move efi_guid_t efi_guid_image_security_database in efi_var_common.c

[PATCH v7 1/3] lib: introduce HASH_CALCULATE option

[Masahisa Kojima]

Build error occurs when CONFIG_EFI_SECURE_BOOT or
CONFIG_EFI_CAPSULE_AUTHENTICATE is enabled,
because hash-checksum.c is not compiled.

Since hash_calculate() implemented in hash-checksum.c can be
commonly used aside from FIT image signature verification,
this commit itroduces HASH_CALCULATE option to decide
if hash-checksum.c shall be compiled.

Signed-off-by: Masahisa Kojima 
---

Changes in v7:
- newly introduce HASH_CALCULATE option

Changes in v6:
- update lib/Makefile to compile hash-checksum.c, instead of
  selecting FIT_SIGNATURE in secure boot and capsule authentication.

Changes in v5:
- Missing option for EFI_TCG2_PROTOROL already added in different commit.
  This commit adds FIT_SIGNATURE only.

Changes in v4:
- newly added in this patch series, due to rebasing
  the base code.

configuration.

map_to_sysmem() will give you a 32-bit wide address. Yes SMBIOS is
legacy and designed for 4GB.

Well the patch was applied because tests passed. We should be careful

[PATCH 1/1] test: revert Don't unmount not (yet) mounted system

Since commit 1ba21bb06b08 ("test: Don't unmount not (yet) mounted system")
the following tests are skipped:

test/py/tests/test_fs/test_basic.py
test/py/tests/test_fs/test_ext.py

Re: [PATCH v2 4/4] test: Don't unmount not (yet) mounted system

[Heinrich Schuchardt]

On 2/11/21 3:40 PM, Andy Shevchenko wrote:

When test suite tries to create a file for a new filesystem test case and fails,
the clean up of the exception tries to unmount the image, that has not yet been
mounted. When it happens, the fuse_mounted global variable is set to False and
inconveniently the test case tries to use sudo, so without this change the
admin of the machine gets an (annoying) email:

   Subject: *** SECURITY information for example.com ***

   example.com : Feb  5 19:43:47 : ... COMMAND=/bin/umount 
.../build-sandbox/persistent-data/mnt

and second run of the test cases on uncleaned build folder will ask for sudo
which is not what expected.

Besides that there is a double unmount calls during successfully run test case.

All of these due to over engineered Python try-except clause and people didn't
get it properly at all. The rule of thumb is that don't use more keywords than
try-except in the exception handling code. Nevertheless, here we adjust code
to be less intrusive to the initial logic behind that complex and unclear
constructions in the test case, although it adds a lot of lines of the code,
i.e. splits one exception handler to three, so on each step we know what
cleanup shall perform.

Dear Andy,

with this merged patch the following tests are not executed anymore locally:

test/py/tests/test_fs/test_basic.py
test/py/tests/test_fs/test_ext.py

SKIPPED [13] test/py/tests/test_fs/conftest.py:350: Setup failed for
filesystem: ext4. Command 'guestmount -a
build-sandbox/persistent-data/3GB.ext4.img -m /dev/sda
build-sandbox/persistent-data/mnt' returned non-zero exit status 1.

Please, revert the patch or fix it.

Best regards

Heinrich
