954fd730ca Allow protocol to be separated from host with a semicolon
Some DHCP servers (such as dnsmasq) tokenise parameters with commas, making
it impossible to pass boot files with commas in them. Allow using a semicolon
to separate the protocol from host if a comma wasn't found.

ec0051a569 Don't allocate a new address buffer if we receive multiple responses
The current logic in the DNS resolution code allocates an address buffer
based on the number of addresses in the response packet. If we receive
multiple response packets in response to a single query packet, this means
that we will reallocate a new buffer large enough for only the addresses in
that specific packet, discarding any previous results in the process. Worse,
we still keep track of the *total* number of addresses resolved in response
to this query, not merely the number in the packet being currently processed.
Use realloc() rather than malloc() to avoid overwriting the existing data,
and allocate a buffer large enough for the total set of addresses rather
than merely the number in this specific response.

bb3473d7c8 Rework TPM measurements
Rework TPM measurements to use fewer PCRs. After discussion with upstream,
it's preferable to avoid using so many PCRs. Instead, measure into PCRs 8
and 9 but use a prefix in the event log to indicate which subsystem carried
out the measurements.

f4d35d49e3 configure: set -fno-pie together with -fno-PIE
OpenBSD 5.9 apparently defaults to -fpie. We use -fno-PIE when appropriate
already, but that is not enough - it does not turn off -fpie.

Actually check for -fPIE is not precise enough. __PIE__ is set for both
-fpie and -fPIE but with different values. As far as I can tell, both
options were introduced at the same time, so both should always be supported.

This fixes compilation on OpenBSD 5.9 which otherwise created insanely big
lzma_decompress.img.

76eac44af3 Remove the variable oldname which is attempting to free stack space.
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.

51f375d688 efidisk: Respect block_io_protocol buffer alignment
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.

b00e4c2bd9 efidisk: prevent errors from diskfilter scan of removable drives
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.

eb9f401fc1 net: fix ipv6 routing
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,

bc220962e3 ieee1275: prevent buffer over-read
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:

625934ec0f menu_entry: Disable cursor during update_screen()
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().
