Subject: [PATCH 0/2] Fix boot hang issue on Ampere Emag server

I met a hung task warning and then kernel was hung forever with latest
kernel on an Ampere Emag server.

The root cause is kernel was hung when invoking an efi rts call to set
the RandomSeed variable during the booting stage. The arch_efi_call_virt
call (set_variable) was never returned and then caused the hung task error.

On the Emag server, efi_rt_services_supported(EFI_RT_SUPPORTED_SET_VARIABLE)
is returned with "true"

Fix it by introducing the efi_get_supported_rt_services() and then determine
to set or clear the runtime services bit of efi.flags.

Subject: [PATCH 1/2] efi: libstub: Fix the retriving of supported rutime services

If retrieving UEFI configuration table is failed, the supported runtime
services mask should be regarded as 0 instead of EFI_RT_SUPPORTED_ALL.
Otherwise efi_novamap might be incorrectly assigned to "false" on the
Ampere Emag server.

Subject: [PATCH 2/2] efi: Introduce efi_get_supported_rt_services() to get the runtime services mask

Previously, efi.runtime_supported_mask will always be the initial value
EFI_RT_SUPPORTED_ALL and can't be retrieved in efi_config_parse_tables()
if rt_prop is EFI_INVALID_TABLE_ADDR. Thus this can cause the wrong
return value of efi_rt_services_supported(EFI_RT_SUPPORTED_SET_VARIABLE)
on the Ampere Emag server.

Besides, abstract the runtime services retrieving into a new exported
helper efi_get_supported_rt_services() to set or clear the runtime service
bit of efi.flags.

Hello Justin,

This is not how things are supposed to work. On systems that do not
implement the RT properties table, all runtime services are assumed to
be implemented.

Note that this table is informational only - the runtime services
themselves must be callable and return EFI_UNSUPPORTED if they are
marked as unavailable in the RT properties table.

This is not right. There are now other users of the EFI runtime
service infrastructure (ACPI PRM), so even if all EFI runtime services
are marked as unsupported, we should still set the
EFI_RUNTIME_SERVICES bit if the EFI runtime memory map is provided.

Given that EFI variables work on this platform (as far as I know), the
problem may be that we are calling SetVariable() too early.

Could you double check whether setting variables works as expected?
You can use efibootmgr -t 10 as root (for example) to set the boot
timeout, and check whether the new value is retained after a reboot
(efibootmgr will print the current value for you)

Could you also please share the kernel log up until the point where it hangs?

This is as expected: if the firmware does not expose the RT properties
table, all runtime services are assumed to be available.

On my phone and with very limited connectivity for another 10 days, but
I wonder if there's a later place we could move this block:

if (efi_rt_services_supported(EFI_RT_SUPPORTED_SET_VARIABLE))
execute_with_initialized_rng(&refresh_nv_rng_seed_nb);

Is there any additional initialization that happens after
efisubsys_init() that we're maybe missing out on there?

From Jia's dmesg:

[ 14.209389][ C2] random: crng init done

So SetVariable isn't even being called until 14 seconds after boot. That
suggests there's something else wrong here. I wonder how it is that
efibootmgr works, but this does not... Hm?

I think what we want to learn is whether efibootmgr -t 10 works in the
latest RC. If not, it would suggest the issue isn't with the seed
setting, but with some other unrelated change.

Can you run efibootmgr -t 10 (or whatever) again on a kernel where
you've commented out these lines in efi.c inside of efisubsys_init():

if (efi_rt_services_supported(EFI_RT_SUPPORTED_SET_VARIABLE))
execute_with_initialized_rng(&refresh_nv_rng_seed_nb);

-->

// if (efi_rt_services_supported(EFI_RT_SUPPORTED_SET_VARIABLE))
// execute_with_initialized_rng(&refresh_nv_rng_seed_nb);

Or something like that.

As your suggested (comment above execute_with_initialized_rng in latest kernel):
The efibootmgr -t X will be hung. Looks like one certain commit before your patch
broke the set_variable efi call. I will dig into the further debug and tell you the result.

The root cause of the hung IMO might be similar to
commit 550b33cfd445296868a478e8413ffb2e963eed32
Author: Ard Biesheuvel <[email protected]>

arm64: efi: Force the use of SetVirtualAddressMap() on Altra machines

Do you agree with the idea if I add Ampere ”eMAG” machine into the list of
Using SetVirtualAddressMap() forcibly?

Please note that even in previous kernel patch, the efibootmgr -t 10 will make
kernel hung if I passed "efi=novamap" to the boot parameter.

Interesting. What does dmidecode return for the family in the type 1 record?

Yes, it works on my eMAG server: the kernel boots.
Other than efibootmgr failure. But I noticed this efibootmgr failure even before
Commit d3549a938b7 ("avoid SetVirtualAddressMap() when possible ")

root@:~/linux# efibootmgr -t 9; efibootmgr -t 5;
Could not set Timeout: Input/output error

Do you get any [Firmware Bug] lines in the kernel log?

No,
I built the kernel based on:
commit d2d11f342b179f1894a901f143ec7c008caba43e (HEAD -> master, origin/master, origin/HEAD)
Author: Linus Torvalds <[email protected]>
Date: Sun Feb 5 17:17:10 2023 -0800

Merge branch 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

Are you worried about your sync exception fixup patch? I think it has been included.

On an Ampere *Altra* server, the family name seems to not follow your purpose of invoking efi_get_smbios_string(1, family).

dmidecode |grep -i family -C 10

Handle 0x0001, DMI type 1, 27 bytes
