Fall back to non-EFI if booted using EFI but -efi is missing

It may be possible, particularly in recovery situations, to be booted
using EFI on x86 when only the i386-pc target is installed, or on ARM
when only the arm-uboot target is installed.  There's nothing actually

it's better than returning a confusing error.

hfsplus: Fix gcc9 error with -Waddress-of-packed-member

The catkey->name could be unaligned since the address of 'void* record'
is calculated as offset in bytes to a malloc buffer.

The fix is using aligned buffer allocated by grub_malloc for holding
the UTF16 string copied from catkey->name. And use that buffer as
argument for grub_utf16_to_utf8 to convert to UTF8 strings.

In addition, using a new copy of buffer rather than catkey->name itself
for processing the endianess conversion, we can also get rid of the hunk
restoring byte order of catkey->name to what it was previously.

5 years agoieee1275: obdisk driver
Eric Snowberg [Tue, 5 Mar 2019 01:27:39 +0000 (17:27 -0800)]
ieee1275: obdisk driver

Add a new disk driver called obdisk for IEEE1275 platforms.  Currently
the only platform using this disk driver is SPARC, however other IEEE1275
platforms could start using it if they so choose.  While the functionality
within the current IEEE1275 ofdisk driver may be suitable for PPC and x86, it
presented too many problems on SPARC hardware.

Within the old ofdisk, there is not a way to determine the true canonical
name for the disk.  Within Open Boot, the same disk can have multiple names
but all reference the same disk.  For example the same disk can be referenced
by its SAS WWN, using this form:

/pci@302/pci@2/pci@0/pci@17/LSI,sas@0/disk@w5000cca02f037d6d,0

It can also be referenced by its PHY identifier using this form:

/pci@302/pci@2/pci@0/pci@17/LSI,sas@0/disk@p0

It can also be referenced by its Target identifier using this form:

/pci@302/pci@2/pci@0/pci@17/LSI,sas@0/disk@0

Also, when the LUN=0, it is legal to omit the ,0 from the device name.  So with
the disk above, before taking into account the device aliases, there are 6 ways
to reference the same disk.

Then it is possible to have 0 .. n device aliases all representing the same disk.
Within this new driver the true canonical name is determined using the the
IEEE1275 encode-unit and decode-unit commands when address_cells == 4.  This
will determine the true single canonical name for the device so multiple ihandles
are not opened for the same device.  This is what frequently happens with the old
ofdisk driver.  With some devices when they are opened multiple times it causes
the entire system to hang.

Another problem solved with this driver is devices that do not have a device
alias can be booted and used within GRUB. Within the old ofdisk, this was not
possible, unless it was the original boot device.  All devices behind a SAS
or SCSI parent can be found.   Within the old ofdisk, finding these disks
relied on there being an alias defined.  The alias requirement is not
necessary with this new driver.  It can also find devices behind a parent
after they have been hot-plugged.  This is something that is not possible
with the old ofdisk driver.

The old ofdisk driver also incorrectly assumes that the device pointing to by a
device alias is in its true canonical form. This assumption is never made with
this new driver.

Another issue solved with this driver is that it properly caches the ihandle
for all open devices.  The old ofdisk tries to do this by caching the last
opened ihandle.  However this does not work properly because the layer above
does not use a consistent device name for the same disk when calling into the
driver.  This is because the upper layer uses the bootpath value returned within
/chosen, other times it uses the device alias, and other times it uses the
value within grub.cfg.  It does not have a way to figure out that these devices
are the same disk.  This is not a problem with this new driver.

Due to the way GRUB repeatedly opens and closes the same disk. Caching the
ihandle is important on SPARC.  Without caching, some SAS devices can take
15 - 20 minutes to get to the GRUB menu. This ihandle caching is not possible
without correctly having the canonical disk name.

When available, this driver also tries to use the deblocker #blocks and
a way of determining the disk size.

Finally and probably most importantly, this new driver is also capable of
seeing all partitions on a GPT disk.  With the old driver, the GPT
partition table can not be read and only the first partition on the disk
can be seen.

gnulib: Upgrade Gnulib and switch to bootstrap tool

Upgrade Gnulib files to 20190105.

It's much easier to maintain GRUB's use of portability support files
from Gnulib when the process is automatic and driven by a single
configuration file, rather than by maintainers occasionally running
gnulib-tool and committing the result.  Removing these
automatically-copied files from revision control also removes the
temptation to hack the output in ways that are difficult for future
maintainers to follow.  Gnulib includes a "bootstrap" program which is
designed for this.

The canonical way to bootstrap GRUB from revision control is now
"./bootstrap", but "./autogen.sh" is still useful if you just want to
generate the GRUB-specific parts of the build system.

GRUB now requires Autoconf >= 2.63 and Automake >= 1.11, in line with
Gnulib.

Gnulib source code is now placed in grub-core/lib/gnulib/ (which should
not be edited directly), and GRUB's patches are in
grub-core/lib/gnulib-patches/.  I've added a few notes to the developer
manual on how to maintain this.

util: Detect more I/O errors

Many of GRUB's utilities don't check anywhere near all the possible
write errors.  For example, if grub-install runs out of space when
copying a file, it won't notice.  There were missing checks for the
return values of write, fflush, fsync, and close (or the equivalents on
other OSes), all of which must be checked.

I tried to be consistent with the existing logging practices of the
various hostdisk implementations, but they weren't entirely consistent
to start with so I used my judgement.  The result at least looks
reasonable on GNU/Linux when I provoke a write error:

  Installing for x86_64-efi platform.
  grub-install: error: cannot copy `/usr/lib/grub/x86_64-efi-signed/grubx64.efi.signed' to `/boot/efi/EFI/debian/grubx64.efi': No space left on device.

There are more missing checks in other utilities, but this should fix
the most critical ones.

travis: Add Travis CI config file

There is a really convenient service for open source project from Travis
CI: They allow for free CI testing using their infrastructure.

GRUB has had issues with broken builds for various targets for a long time
already. The main reason is a lack of CI to just do smoke tests on whether
all targets still at least compile.

This patch adds a Travis config file which builds (almost) all currently
available targets.

On top of that, this Travis config also runs a small execution test on the
x86_64-efi target.

All of this config file can easily be extended further on. It probably
makes sense to do something similar to the u-boot test infrastructure
that communicates with the payload properly. Going forward, we also will
want to do more QEMU runtime checks for other targets.

Currently, with this config alone, I already see about half of the available
targets as broken. So it's definitely desperately needed :).

normal/menu: Do not treat error values as key presses

Some terminals, like `grub-core/term/at_keyboard.c`, return `-1` in case
they are not ready yet.

      if (! KEYBOARD_ISREADY (grub_inb (KEYBOARD_REG_STATUS)))
        return -1;

Currently, that is treated as a key press, and the menu time-out is
cancelled/cleared. This is unwanted, as the boot is stopped and the user
manually has to select a menu entry. Therefore, adapt the condition to
require the key value also to be greater than 0.

`GRUB_TERM_NO_KEY` is defined as 0, so the condition could be collapsed
to greater or equal than (≥) 0, but the compiler will probably do that
for us anyway, so keep the cases separate for clarity.

This is tested with coreboot, the GRUB default payload, and the
configuration file `grub.cfg` below.

For GRUB:

    $ ./autogen.sh
    $ ./configure --with-platform=coreboot
    $ make -j`nproc`
    $ make default_payload.elf

For coreboot:

    $ more grub.cfg
    serial --unit 0 --speed 115200
    set timeout=5

    menuentry 'halt' {
        halt
    }
    $ build/cbfstool build/coreboot.rom add-payload \
        -f /dev/shm/grub/default_payload.elf -n fallback/payload -c lzma
    $ build/cbfstool build/coreboot.rom add -f grub.cfg -n etc/grub.cfg -t raw

    $ qemu-system-x86_64 -M pc -bios build/coreboot.rom -serial stdio -nic none

Currently, the time-out is cancelled/cleared. With the commit, it is not.
With a small GRUB payload, this the problem is also reproducible on the
ASRock E350M1.
