b59db4f484 chainloader: patch in BPB's sectors_per_track and num_heads
These fields must reflect the ROM-BIOS's geometry for CHS-based
loaders to correctly load their next stage. Most loaders do not
query the ROM-BIOS (Int13.08), relying on the BPB fields to hold
the correct values already.

Tested with lDebug booted in qemu via grub2's
FreeDOS direct loading support, refer to
https://bitbucket.org/ecm/ldosboot + https://bitbucket.org/ecm/ldebug
(For this test, lDebug's iniload.asm must be assembled with
-D_QUERY_GEOMETRY=0 to leave the BPB values provided by grub.)

no-data-command ( cmd-addr -- error? )
Executes a simple SCSI command, automatically retrying under
certain conditions.  cmd-addr is the address of a 6-byte command buffer
containing an SCSI command that does not have a data transfer phase.
Executes the command, retrying indefinitely with the same retry criteria
as retry-command.

error? is nonzero if an error occurred, zero otherwise.
NOTE no-data-command is a convenience function. It provides
no capabilities that are not present in retry-command, but for
those commands that meet its restrictions, it is easier to use.

On systems which are not based on Open Firmware but have at

trying to append the disk name to of_path will result in a
crash.

The proper behavior of of_path_of_nvme is, however, to just
return NULL in such cases, like other users of find_obppath,

9363f738ba libgcrypt: Import replacement CRC operations
The CRC implementation imported from libgcrypt 1.5.3 is arguably
non-free, due to being encumbered by the restrictive Internet Society
licence on RFCs (see e.g. https://wiki.debian.org/NonFreeIETFDocuments).
Fortunately, libgcrypt has since replaced it with a version that is both
reportedly better-optimised and doesn't suffer from this encumbrance.

The ideal solution would be to update to a new version of libgcrypt, and
I spent some time trying to do that.  However, util/import_gcry.py
requires complex modifications to cope with the new version, and I
stalled part-way through; furthermore, GRUB's libgcrypt tree already
contains some backports of upstream changes.  Rather than allowing the
perfect to be the enemy of the good, I think it's best to backport this
single change to at least sort out the licensing situation.  Doing so
won't make things any harder for a future wholesale upgrade.

This commit is mostly a straightforward backport of
https://git.gnupg.org/cgi-bin/gitweb.cgi?p=libgcrypt.git;a=commitdiff;h=06e122baa3321483a47bbf82fd2a4540becfa0c9,
but I also imported bufhelp.h from libgcrypt 1.7.0 (newer versions
required further changes elsewhere).

I've tested that "hashsum -h crc32" still produces correct output for a
variety of files on both i386-pc and x86_64-emu targets.

5826e32c37 chainloader: Fix wrong break condition (must be AND not, OR)
The definition of bpb's num_total_sectors_16 and num_total_sectors_32
is that either the 16-bit field is non-zero and is used (in which case
eg mkfs.fat sets the 32-bit field to zero), or it is zero and the
32-bit field is used. Therefore, a BPB is invalid only if *both*
fields are zero; having one field as zero and the other as non-zero is
the case to be expected. (Indeed, according to Microsoft's specification
one of the fields *must* be zero, and the other non-zero.)

This affects all users of grub_chainloader_patch_bpb which are in
chainloader.c, freedos.c, and ntldr.c

Some descriptions of the semantics of these two fields:

https://www.win.tue.nl/~aeb/linux/fs/fat/fat-1.html

  The old 2-byte fields "total number of sectors" and "number of
  sectors per FAT" are now zero; this information is now found in
  the new 4-byte fields.

(Here given in the FAT32 EBPB section but the total sectors 16/32 bit
fields semantic is true of FAT12 and FAT16 too.)

https://wiki.osdev.org/FAT#BPB_.28BIOS_Parameter_Block.29

  19 | 2 | The total sectors in the logical volume. If this value is 0,
  it means there are more than 65535 sectors in the volume, and the actual
  count is stored in "Large Sectors (bytes 32-35).

  32 | 4 | Large amount of sector on media. This field is set if there
  are more than 65535 sectors in the volume.

(Doesn't specify what the "large" field is set to when unused, but as
mentioned mkfs.fat sets it to zero then.)

https://technet.microsoft.com/en-us/library/cc976796.aspx

  0x13 | WORD | 0x0000 |
  Small Sectors . The number of sectors on the volume represented in 16
  bits (< 65,536). For volumes larger than 65,536 sectors, this field
  has a value of zero and the Large Sectors field is used instead.

  0x20 | DWORD | 0x01F03E00 |
  Large Sectors . If the value of the Small Sectors field is zero, this
  field contains the total number of sectors in the FAT16 volume. If the
  value of the Small Sectors field is not zero, the value of this field
  is zero.

https://staff.washington.edu/dittrich/misc/fatgen103.pdf page 10

  BPB_TotSec16 | 19 | 2 |
  This field is the old 16-bit total count of sectors on the volume.
  This count includes the count of all sectors in all four regions of the
  volume. This field can be 0; if it is 0, then BPB_TotSec32 must be
  non-zero. For FAT32 volumes, this field must be 0. For FAT12 and
  FAT16 volumes, this field contains the sector count, and
  BPB_TotSec32 is 0 if the total sector count “fits” (is less than
  0x10000).

  BPB_TotSec32 | 32 | 4 |
  This field is the new 32-bit total count of sectors on the volume.
  This count includes the count of all sectors in all four regions of the
  volume. This field can be 0; if it is 0, then BPB_TotSec16 must be
  non-zero. For FAT32 volumes, this field must be non-zero. For
  FAT12/FAT16 volumes, this field contains the sector count if
  BPB_TotSec16 is 0 (count is greater than or equal to 0x10000).

(This specifies that an unused BPB_TotSec32 field is set to zero.)

By the way fix offsets in include/grub/fat.h.

984c022638 sparc64: fix OF path names for sun4v systems
Fix the Open Firmware (OF) path property for sun4v SPARC systems.
These platforms do not have a /sas/ within their path. Over time
different OF addressing schemes have been supported. There
is no generic addressing scheme that works across every HBA.

It looks that this functionality will not work if you try to cross-install
SPARC GRUB2 binary using e.g. x86 grub-install. By default it should work.
However, we will also have other issues here, like lack of access to OF
firmware/paths, which make such configs unusable anyway. So, let's leave
this patch as is for time being. If somebody cares then he/she should fix
the issue(s) at some point.

d97d20da82 ahci: Improve error handling
Check the error bits in the interrupt status register. According to the
AHCI 1.2 spec, "Interrupt sources that are disabled (‘0’) are still
reflected in the status registers.", so this should work even though
grub uses polling

This fixes the following problem on a Fujitsu E744 laptop:

Sometimes there is a very long delay (up to several minutes) when
booting from hard disk. It seems accessing the DVD drive (which has no
disk inserted) sometimes fails with some errors, which leads to each
access being stalled until the 20s timeout triggers. This seems to
happen when grub is trying to read filesystem/partition data.

The problem is that the command_issue bit that is checked in the loop is
only reset if the "HBA receives a FIS which clears the BSY, DRQ, and ERR
bits for the command", but the ERR bit is never cleared. Therefore
command_issue is never reset and grub waits for the timeout.

The relevant bit in our case is the Task File Error Status (TFES), which
is equivalent to the ERR bit 0 in tfd. But this patch also checks
the other error bits except for the "Interface non-fatal error status"
bit.

e224ee31c0 efi: Move grub_reboot() into kernel
The reboot function calls machine_fini() and then reboots the system.
Currently it lives in lib/ which means it gets compiled into the

In a following patch, I want to free the heap on machine_fini()
though, so we would free the memory that the code is running in. That
obviously breaks with smarter UEFI implementations.

So this patch moves it into the core. That way we ensure that all
code running after machine_fini() in the UEFI case is running from
memory that got allocated (and gets deallocated) by the UEFI core.

2da5f067f4 unix exec: avoid atexit handlers when child exits
The `grub_util_exec_redirect_all` helper function can be used to
spawn an executable and redirect its output to some files. After calling
`fork()`, the parent will wait for the child to terminate with
`waitpid()` while the child prepares its file descriptors, environment
and finally calls `execvp()`. If something in the children's setup
fails, it will stop by calling `exit(127)`.

Calling `exit()` will cause any function registered via `atexit()` to be
executed, which is usually the wrong thing to do in a child. And
actually, one can easily observe faulty behaviour on musl-based systems
without modprobe(8) installed: executing `grub-install --help` will call
`grub_util_exec_redirect_all` with "modprobe", which obviously fails if
modprobe(8) is not installed. Due to the child now exiting and invoking
the `atexit()` handlers, it will clean up some data structures of the
parent and cause it to be deadlocked in the `waitpid()` syscall.

The issue can easily be fixed by calling `_exit(127)` instead, which is
especially designed to be called when the atexit-handlers should not be
executed.

682b3134b6 * grub-core/fs/udf.c: Add support for UUID
Use same algorithm as in libblkid from util-linux v2.30.

1. Take first 16 bytes from UTF-8 encoded string of VolumeSetIdentifier
2. If all bytes are hexadecimal digits, convert to lowercase and use as UUID
3. If first 8 bytes are not all hexadecimal digits, convert those 8 bytes
   to their hexadecimal representation, resulting in 16 bytes for UUID
4. Otherwise, compose UUID from two parts:
   1. part: converted first 8 bytes (which are hexadecimal digits) to lowercase
   2. part: encoded following 4 bytes to their hexadecimal representation (16 bytes)

So UUID would always have 16 hexadecimal digits in lowercase variant.

According to UDF specification, first 16 Unicode characters of
VolumeSetIdentifier should be unique value and first 8 should be
hexadecimal characters.

In most cases all 16 characters are hexadecimal, but e.g. MS Windows
format.exe set only first 8 as hexadecimal and remaining as fixed
(non-unique) which violates specification.

4aaa6b639d Allow GRUB to mount ext2/3/4 filesystems that have the encryption feature.
On such a filesystem, inodes may have EXT4_ENCRYPT_FLAG set.
For a regular file, this means its contents are encrypted; for a
directory, this means the filenames in its directory entries are
encrypted; and for a symlink, this means its target is encrypted.  Since
GRUB cannot decrypt encrypted contents or filenames, just issue an error
if it would need to do so.  This is sufficient to allow unencrypted boot
files to co-exist with encrypted files elsewhere on the filesystem.

(Note that encrypted regular files and symlinks will not normally be
encountered outside an encrypted directory; however, it's possible via
hard links, so they still need to be handled.)

Tested by booting from an ext4 /boot partition on which I had run
'tune2fs -O encrypt'.  I also verified that the expected error messages
are printed when trying to access encrypted directories, files, and
symlinks from the GRUB command line.  Also ran 'sudo ./grub-fs-tester
ext4_encrypt'; note that this requires e2fsprogs v1.43+ and Linux v4.1+.

da4e8334b2 sparc64: Don't use devspec to determine the OBP path
Don't use devspec to determine the OBP path on SPARC hardware.  Within all
versions of Linux on SPARC, the devspec returns one of three values:
"none", "vnet-port", or "vdisk".  Unlike on PPC, none of these values
are useful in determining the OBP path.

Before this patch grub-ofpathname always returned the wrong value
for a virtual disk. For example:

% grub-ofpathname /dev/vdiskc2
vdisk/disk@2:b

After this patch it now returns the correct value:

% grub-ofpathname /dev/vdiskc2
/virtual-devices@100/channel-devices@200/disk@2:b

x86-64 assembler generates R_X86_64_PLT32, instead of R_X86_64_PC32, for
32-bit PC-relative branches.  Grub2 should treat R_X86_64_PLT32 as

721b4677ab Fix packed-not-aligned error on GCC 8
When building with GCC 8, there are several errors regarding packed-not-aligned.

./include/grub/gpt_partition.h:79:1: error: alignment 1 of ‘struct grub_gpt_partentry’ is less than 8 [-Werror=packed-not-aligned]

This patch fixes the build error by cleaning up the ambiguity of placing
aligned structure in a packed one. In "struct grub_btrfs_time" and "struct
grub_gpt_part_type", the aligned attribute seems to be superfluous, and also
has to be packed, to ensure the structure is bit-to-bit mapped to the format
laid on disk. I think we could blame to copy and paste error here for the
mistake. In "struct efi_variable", we have to use grub_efi_packed_guid_t, as
the name suggests. :)
