From b98ba8921010d03f46704a476c69861515deb1ca Mon Sep 17 00:00:00 2001
From: Peter Jones <pjones@redhat.com>
Date: Mon, 7 Jan 2019 10:30:59 -0500
Subject: [PATCH] dp.h: make format_guid() handle misaligned guid pointers
safely.
GCC 9 adds -Werror=address-of-packed-member, which causes us to see the
build error reported at
https://bugzilla.opensuse.org/show_bug.cgi?id=1120862 .
That bug report shows us the following:
In file included from dp.c:26:
dp.h: In function 'format_vendor_helper':
dp.h:120:37: error: taking address of packed member of 'struct <anonymous>' may result in an unaligned pointer value [-Werror=address-of-packed-member]
120 | format_guid(buf, size, off, label, &dp->hw_vendor.vendor_guid);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~
dp.h:74:25: note: in definition of macro 'format_guid'
74 | _rc = efi_guid_to_str(guid, &_guidstr); \
| ^~~~
cc1: all warnings being treated as errors
This patch makes format_guid() use a local variable as a bounce buffer
in the case that the guid we're passed is aligned as chaotic neutral.
Note that this only fixes this instance and there may be others that bz
didn't show because it exited too soon, and I don't have a gcc 9 build
in front of me right now.

Subject: [PATCH] Fix all the places -Werror=address-of-packed-member catches.
This gets rid of all the places GCC 9's -Werror=address-of-packed-member
flags as problematic.

Subject: [PATCH] Fix another error of -Werror=address-of-packed-member
Android 9 clang complains:
external/efivar/src/dp-message.c:367:24: error: taking address of packed member '' of class or structure 'efidp_infiniband' may result in an unaligned pointer value [-Werror,-Waddress-of-packed-member]

^~~~~~~~~~~~~~~~~~~~~~~

memmove(&_guid, guid, sizeof(_guid)); \
^~~~
1 error generated.
Since commit c3c553d the fifth parameter of format_guid() is treated as
a const void *. The casting is unnecessary.
