[PATCH 0/5] Add extra sanity checks on mmap'd physical memory

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

URGENT for July release

It has been reported that the BIOS32 test generates a SIGBUS when reading
a memory mapped physical region on aarch64 platforms.  To catch
non-readable mappings like this I've added some precautionary memory read
checks.  There are some other mappings like this in fwts, but these are
the ones I'm primarily mostly concerned about for the current July release
of fwts.

Colin Ian King (5):
  dmi: dmicheck: ensure mmap'd SMBIOS data is readable before accessing
    it
  bios32: ensure mmap'd memory is readable before accessing it
  bios: ebdadump: ensure mmap'd memory is readable before accessing it
  bios: romdump: ensure mmap'd memory is readable before accessing it
  lib: fwts_smbios: ensure mmap'd memory is readable before accessing it
