server cannot be NULL at this point (we return error earlier if it is).
Also structure is zalloc'ed, so no need to explicitly initialize
members to 0.

Condition was apparently reversed so GRUB assumed all devices were
files. This later made it skip BLKFLSBUF ioctl on Linux which caused
various page cache coherency issues. Observed were
- failure to validate blocklist install (read content did not match
just written)
- failure to detect Linux MD on disk after online hot addition
(GRUB got stale superblock)

grub_xfs_iterate_dir did not restore first character after inline
name when match was found. Dependning on XFS format this character
could be inode number and we could return to the same node later in
find_file if processing cycled symlinks.
CID: 86724
If line contains single word, line and argv[0] are aliases, so
no NULL dereference is possible, but Coverity does not know it.
Change code to avoid ambiguity and also remove redundant call to
grub_strchr.

Currently only Windows gets distinguished icons, everything else is displayed
using the same generic one. Add additional --class based on os-prober returned
label, which usually is expected to match primary distribution name.
Also use it for Windows as well - chainloader prober may actually return
different strings (Windows, MS-DOS, Windows9xME).
This was lost when code was refactored. Patch restores previous behavior.
It is still not clear whether this is the right one. Due to the way we
detect DM abstraction, partitions on DM are skipped, we fall through to
generic detection which ends up in assuming parent device is BIOS disk.
It is useful to install GRUB on VM disk from the host. But it also means
that GRUB will mistakenly allow install on real system as well.
For now let's fix regression; future behavior needs to be discussed.

GRUB keeps partition offset and size in units of 512B sectors. Media paths
are defined in terms of LBA which are presumed to match HDD sector size.
This is probably cosmetic (EFI requires that partition is searched by GUID)
and still incorrect if GPT was created using different logical block size.
But current code is obviously wrong and new has better chances to be correct.
Otherwise it causes subsequent file open to fail, because grub_file_open
misinterprets set grub_errno for grub_file_get_device_name failure.

gnulib files are already handled by recursive make distdir invocation.
Including all generated headers (after make completed) causes build
failure if target system is different (different compile version etc).
Macports add extra information after version itself:
$flex --version
flex 2.5.35 Apple(flex-31)
We require at least felx 2.5.35 so do not need to care about prehistoric
"flex version n.n.n"; just use second field always.

This makes it impossible to read from stdin without controlling tty:
10:/mnt # echo -e passwd\\npasswd | setsid ./grub-mkpasswd-pbkdf2
Enter password:
Reenter password: ./grub-mkpasswd-pbkdf2: error: failure to read password.

This did not cause real problem but is good for reproducible builds. I hit
it with recent bootinfoscript that displays embedded config; I was puzzled
by random garbage at the end.
Prezero memory buffer used to assemble core.img. This makes individual
memset redundant. Also ensure buffer is filled with zeroes in several other
places.
Also remove redundant zeroing code where we fill in the whole memory block
anyway.
GRUB code expects O32 or N32. N32 is less tested than O32, so we prefer to
compile with O32. Some systems (e.g. GNU Guix) default to using newer
n64 or n32 ABI. Try to find suitable options to force o32.
For GCC this is simply -mabi=32. While clang supports this option as well,
o32 ABI is valid for MIPS target and n32/64 ABI are valid for MIPS64 target
only, so use "-target mips/mipsel -mabi=32".

From original patch by dann frazier <dann.frazier@canonical.com>:
grub_net_fs_open() saves off a copy of the file structure it gets passed and
uses it to create a bufio structure. It then overwrites the passed in file
structure with this new bufio structure. Since file->name doesn't get set
until we return back to grub_file_open(), it means that only the bufio
structure gets a valid file->name. The "real" file's name is left
uninitialized. This leads to a crash when the progress module hook is called
on it.
grub_net_fs_open() already saved copy of file name as ->net->name, so change
progress module to use it.
Also, grub_file_open may leave file->name as NULL if grub_strdup fails. Check
for it.

It cannot work anyway because host disk cannot be read. This fixes hostfs access
on native Windows build where filenames start with '\' or do not have initial
separator at all (d:\foo).
Issue was observed when running grub-fstest on Windows. On UNIX image name is
canonicalized to always start with `/' so this was not noticed.
This has side effect of allowing relative path names on host, but this already
was the case with `ls' command, so it just extends it to all commands.

Exclusive open on SNP will close all existing protocol instances which
may disable all receive filters on interface. Reinstall them after we

Also follow UEFI specification recommendation and stop interfaces when

"Access to menuentry" is a bit vague - change to "execute menuentry"

From RFC1542:
The 'giaddr' field is rather poorly named. It exists to facilitate
the transfer of BOOTREQUEST messages from a client, through BOOTP
relay agents, to servers on different networks than the client.
Similarly, it facilitates the delivery of BOOTREPLY messages from the
servers, through BOOTP relay agents, back to the client. In no case
does it represent a general IP router to be used by the client. A
BOOTP client MUST set the 'giaddr' field to zero (0.0.0.0) in all
BOOTREQUEST messages it generates.
A BOOTP client MUST NOT interpret the 'giaddr' field of a BOOTREPLY
message to be the IP address of an IP router. A BOOTP client SHOULD
completely ignore the contents of the 'giaddr' field in BOOTREPLY
messages.
Leave code ifdef'd out for the time being in case we see regression.
