      efi: Use 32-bit alignment for efi_guid_t · 494c704f
      Ard Biesheuvel authored 
      The UEFI spec and EDK2 reference implementation both define EFI_GUID as
struct { u32 a; u16; b; u16 c; u8 d[8]; }; and so the implied alignment
is 32 bits not 8 bits like our guid_t. In some cases (i.e., on 32-bit ARM),
this means that firmware services invoked by the kernel may assume that
efi_guid_t* arguments are 32-bit aligned, and use memory accessors that
do not tolerate misalignment. So let's set the minimum alignment to 32 bits.

Note that the UEFI spec as well as some comments in the EDK2 code base
suggest that EFI_GUID should be 64-bit aligned, but this appears to be
a mistake, given that no code seems to exist that actually enforces that
or relies on it.

      efi/memattr: Don't bail on zero VA if it equals the region's PA · 5de0fef0
      Ard Biesheuvel authored 
      The EFI memory attributes code cross-references the EFI memory map with
the more granular EFI memory attributes table to ensure that they are in
sync before applying the strict permissions to the regions it describes.

Since we always install virtual mappings for the EFI runtime regions to
which these strict permissions apply, we currently perform a sanity check
on the EFI memory descriptor, and ensure that the EFI_MEMORY_RUNTIME bit
is set, and that the virtual address has been assigned.

However, in cases where a runtime region exists at physical address 0x0,
and the virtual mapping equals the physical mapping, e.g., when running
in mixed mode on x86, we encounter a memory descriptor with the runtime
attribute and virtual address 0x0, and incorrectly draw the conclusion
that a runtime region exists for which no virtual mapping was installed,
and give up altogether. The consequence of this is that firmware mappings
retain their read-write-execute permissions, making the system more
vulnerable to attacks.

So let's only bail if the virtual address of 0x0 has been assigned to a
physical region that does not reside at address 0x0.

      efi/arm64: Fix debugfs crash by adding a terminator for ptdump marker · 74c953ca
      Qian Cai authored 
      When reading 'efi_page_tables' debugfs triggers an out-of-bounds access here:

  arch/arm64/mm/dump.c: 282
  if (addr >= st->marker[1].start_address) {

called from:

  arch/arm64/mm/dump.c: 331
  note_page(st, addr, 2, pud_val(pud));

because st->marker++ is is called after "UEFI runtime end" which is the
last element in addr_marker[]. Therefore, add a terminator like the one
for kernel_page_tables, so it can be skipped to print out non-existent
markers.

Here's the KASAN bug report:

      "Resource Control" is a very broad term for this CPU feature, and a term
that is also associated with containers, cgroups etc. This can easily
cause confusion.

Make the user prompt more specific. Match the config symbol name.

   under ARM_CPU_RESCTRL and the arch-agnostic bits will be carved out

      Pull arm64 fixes from Will Deacon:
 "Although we're still debugging a few minor arm64-specific issues in
  mainline, I didn't want to hold this lot up in the meantime.

  We've got an additional KASLR fix after the previous one wasn't quite
  complete, a fix for a performance regression when mapping executable
  pages into userspace and some fixes for kprobe blacklisting. All
  candidates for stable.

  Summary:

   - Fix module loading when KASLR is configured but disabled at runtime

   - Fix accidental IPI when mapping user executable pages

   - Ensure hyp-stub and KVM world switch code cannot be kprobed"

* tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux:
  arm64: hibernate: Clean the __hyp_text to PoC after resume
  arm64: hyp-stub: Forbid kprobing of the hyp-stub
  arm64: kprobe: Always blacklist the KVM world-switch code
  arm64: kaslr: ensure randomized quantities are clean also when kaslr is off
  arm64: Do not issue IPIs for user executable ptes
