Historically this variable hold previous value of filename that
had to be freed if allocated previously. Currently this branch
is entered only if filename was not allocated previously so it
became redundant. It did not cause real problems because grub_free
was not called, but code is confusing and causes compilation error
in some cases.

Fixes compilation on OpenBSD 5.9.

Grub would notify the user if the new config was invalid, however, it
did not exit properly with exit code 1. Added the proper exit code.

Resolves: rhbz#1252311

Reported by: Daniel Kiper

Same fix as in 082bc9f7.

Commit 7290bb56 causes GRUB_DISABLE_LINUX_UUID to be ignored due to
mixing of || and && operators. Add some parens to help with that.

Returned from the OpenProtocol operation, the grub_efi_block_io_media
structure contains the io_align field, specifying the minimum alignment
required for buffers used in any data transfers with the device.

Make grub_efidisk_readwrite() allocate a temporary buffer, aligned to
this boundary, if the buffer passed to it does not already meet the
requirements.

Also sanity check the io_align field in grub_efidisk_open() for
power-of-two-ness and bail if invalid.

This is a no-op on x86 but necessarry on ARM and may be necessarry on MIPS.

For this ensure that all bss sections are merged.

We need this to correctly prelink non-PE relocatable images.

Currently we pass around a lot of pointer. Instead put all relevant data
into one structure.

As a preparation for U-Boot relocations, split emitting PE-relocations
from parsing source ELF-relocations.

util/grub-mkimagexx.c is included in a special way into mkimage.c.
Interoperation between defines makes this very tricky. Instead
just have a clean interface and compile util/grub-mkimage*.c separately
from mkimage.c

kernel_type may be set to the type of failed kernel. This patching-up is
easier than to reflow kernel loading routines.

This just pollutes serial console.

Map EFI_NO_MEDIA to GRUB_ERR_OUT_OF_RANGE that is ignored by diskfilter. This
actually matches pretty close (we obviously attempt to read outside of media)
and avoids adding more error codes.

This affects only internally initiated scans. If read/write from removable is
explicitly requested, we still return an error and text explanation is more
clear for user than generic error.

ipv6 routing in grub2 is broken, we cannot talk to anything outside our local
network or anything that doesn't route in our global namespace.  This patch
fixes this by doing a couple of things

1) Read the router information off of the router advertisement.  If we have a
router lifetime we need to take the source address and create a route from it.

2) Changes the routing stuff slightly to allow you to specify a gateway _and_ an
interface.  Since the router advertisements come in on the link local address we
need to associate it with the global address on the card.  So when we are
processing the router advertisement, either use the SLAAC interface we create
and add the route to that interface, or loop through the global addresses we
currently have on our interface and associate it with one of those addresses.
We need to have a special case here for the default route so that it gets used,
we do this by setting the masksize to 0 to mean it encompasses all networks.
The routing code will automatically select the best route so if there is a
closer match we will use that.

With this patch I can now talk to ipv6 addresses outside of my local network.
Thanks,

grub_device_iterate() ignores device when iterator returns 1, not 0.

Reported by Carlos E. R. <robin.listas@telefonica.net>

Documentation says, bootloader should set reserved field to zero.

Reported by Wink Saville <wink@saville.com>

Add dprintf's on common error paths and remove some entries which are too
noisy.

This prevents non-PCI machines from having USB.

This ensures that abort message is actually visible to the user.

Prevent buffer over-read in grub_machine_mmap_iterate. This was
causing phys_base from being calculated properly. This then
caused the wrong value to be placed in ramdisk_image within
struct linux_hdrs. Which prevented the ramdisk from loading on
boot.

Newer SPARC systems contain more than 8 available memory entries.

For example on a T5-8 with 2TB of memory, the memory layout could
look like this:

When running grub in a VGA console of a KVM pseries guest on PowerPC,
you can see the cursor sweeping over the whole line when entering a
character in editor mode. This is visible because grub always refreshes
the whole line when entering a character in editor mode, and drawing
characters is quite a slow operation with the firmware used for the
powerpc pseries guests (SLOF).
To avoid this ugliness, the cursor should be disabled when refreshing
the screen contents during update_screen().

It's difficult to know all dependencies. Since it's manual and cheap
target anyway, simply always rebuild it.

Withoout this module we may end up in a system where no password is
accepted.

This allows coreboot building system to add extra modules depending
on user config.
