f4b1b48a83 disk/ahci.c: Use defines GRUB_AHCI_HBA_PORT_CMD_SPIN_UP and GRUB_AHCI_HBA_PORT_CMD_POWER_ON
Instead of hard coding `2` and `4` use the macros defined already at the
top of the file. As a consequence, wrap the now too long line.

ca59c24bd0 disk/ahci.c: Add port number to port debug messages
Currently, some messages cannot be mapped to the port they belong to as
the port number is missing from the output. So add `port: n` to the
debug messages.

5082ea6184 remove extra newlines in grub_util_* strings
grub_util_{info,warn,error} already add trailing newlines, so remove
them from format strings. Also trailing full stops are already added.

94f701a826 crypto: restrict cipher block size to power of 2.
All current ciphers have blocks which are power of 2 and it's
unlikely to change. Other block length would be tricky to handle anyway.
This restriction allows avoiding extra divisions.

fc535b32b9 diskfilter: fix double free of lv names for mdraid
Avoid micro-optimization in grub_diskfilter_make_raid and make sure
name and fullname are independent strings. This avoids need to special
case it everywhere else.

Also fix memory leak in failure case in grub_diskfilter_make_raid.

Closes: 41582

e27fdbd686 diskfilter: fix crash in validate_lv for mdraid arrays
Commit 750f4bacd3 put LV validation before
actual vg assignment. Make grub_diskfilter_make_raid to assign ->vg as
happens in other cases for consistency. Also clean up redundant code and add
explicit NULL lv->vg check in validate_lv.

Also fix segment validation in validate_lv; it became obvious when crash
was fixed.

2f73d2733c accept also hdX as alias to native Xen disk name
To be compatible with legacy pv-grub, sort disks by increasing order of handle
value. This allows reusing legacy pv-grub menu.lst which is using hdX names.

ea44693fc8 grub-core/disk/luks.c: fix use after free and memory leaks
configure_ciphers:

- several memory leaks where allocated ciphers were not freed. CID: 73813,
73710

- use after free. It is probably quite innocent as grub is single threaded,
but could potentially be a problem with memory allocator debugger turned on.
CID: 73730

- memory leak. CID: 73854

24024dac7f Fix partmap, cryptodisk, and abstraction handling in grub-mkconfig.
Commit 588744d0dc caused grub-mkconfig
no longer to be forgiving of trailing spaces on grub-probe output
lines, which among other things means that util/grub.d/10_linux.in
no longer detects LVM.  To fix this, make grub-probe's output
delimiting more consistent.  As a bonus, this improves the coverage
of the -0 option.

Fixes Debian bug #735935.
