Hi Matt,

My workstation started instant rebooting with tip.  I bisected it to..

   efi/esrt: Use efi_mem_reserve() and avoid a kmalloc()

..but seems it's really $subject, as box works fine with the below.

No idea what's going boom down in efi_arch_mem_reserve().

OK, that's 56 bytes and yet I realise that at no point in the
efi_mem_reserve() call path do we round up to the nearest page size
even though the EFI memory map only deals with EFI_PAGE_SIZE regions.

Could you try this patch?

Subject: [PATCH] x86/efi: Round EFI memmap reservations to EFI_PAGE_SIZE

Mike reported that his machine started rebooting during boot after,

  commit 8e80632fb23f ("efi/esrt: Use efi_mem_reserve() and avoid a kmalloc()")

The ESRT table on his machine is 56 bytes and at no point in the
efi_arch_mem_reserve() call path is that size rounded up to
EFI_PAGE_SIZE.

Since the EFI memory map only deals with whole pages, inserting an EFI
memory region with 56 bytes results in a new entry covering zero
pages, and completely screws up the calculations for the old regions
that were trimmed.

Round all sizes upwards to the nearest EFI_PAGE_SIZE boundary.

Additionally, efi_memmap_insert() expects the mem::range::end value to
be one less than the end address for the region.

I note that the base is also not aligned to EFI_PAGE_SIZE. Shouldn't we
round that down, too?

i.e. have:

	size += addr % EFI_PAGE_SIZE;
	size = round_up(size, EFI_PAGE_SIZE);
	addr = round_down(base, EFI_PAGE_SIZE);

Thanks,
Mark.

That was what I meant to write, though the two statements aren't
necessarily mutually exclusive. ;)

I'll have to leave it to you and Matt to figure out what the real
solution is -- I'm not familiar with this code and was just
pattern-matching.

Thanks,

No dice.  The numbers changed, but box still goes *poof*.

These addresses are pretty low. Can you try the hacky patch plus
Ricardo's change in commit 3dad6f7f6975 ("x86/efi: Defer efi_esrt_init
until after memblock_x86_fill"). He fixed a bug where it's possible to
run out of memblock regions.

Brilliant. This is what I've got queued up. Thanks everyone.

Subject: [PATCH] x86/efi: Round EFI memmap reservations to EFI_PAGE_SIZE

Mike Galbraith reported that his machine started rebooting during boot
after,

  commit 8e80632fb23f ("efi/esrt: Use efi_mem_reserve() and avoid a kmalloc()")

The ESRT table on his machine is 56 bytes and at no point in the
efi_arch_mem_reserve() call path is that size rounded up to
EFI_PAGE_SIZE, nor is the start address on an EFI_PAGE_SIZE boundary.

Since the EFI memory map only deals with whole pages, inserting an EFI
memory region with 56 bytes results in a new entry covering zero
pages, and completely screws up the calculations for the old regions
that were trimmed.

Round all sizes upwards, and start addresses downwards, to the nearest
EFI_PAGE_SIZE boundary.

Additionally, efi_memmap_insert() expects the mem::range::end value to
be one less than the end address for the region.

Brilliant. This is what I've got queued up. Thanks everyone.

Subject: [PATCH] x86/efi: Round EFI memmap reservations to EFI_PAGE_SIZE

Mike Galbraith reported that his machine started rebooting during boot
after,

  commit 8e80632fb23f ("efi/esrt: Use efi_mem_reserve() and avoid a kmalloc()")

The ESRT table on his machine is 56 bytes and at no point in the
efi_arch_mem_reserve() call path is that size rounded up to
EFI_PAGE_SIZE, nor is the start address on an EFI_PAGE_SIZE boundary.

Since the EFI memory map only deals with whole pages, inserting an EFI
memory region with 56 bytes results in a new entry covering zero
pages, and completely screws up the calculations for the old regions
that were trimmed.

Round all sizes upwards, and start addresses downwards, to the nearest
EFI_PAGE_SIZE boundary.

Additionally, efi_memmap_insert() expects the mem::range::end value to
be one less than the end address for the region.
