Leif Lindholm 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.

Andrei Borzenkov 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.

grub-devel@iam.tj c7f93a20c4 cryptodisk: teach grub_cryptodisk_insert() about partitions (bug #45889)
It is not possible to configure encrypted containers on multiple partitions of
the same disk; after the first one all subsequent fail with

disk/cryptodisk.c:978: already mounted as crypto0

Store partition offset in cryptomount descriptor to distinguish between them.

Vladimir Serbinenko 94f701a826 crypto: restrict cipher block size to power of 2.
All current ciphers have blocks which are power of 2 and it's

This restriction allows avoiding extra divisions.

Andrei Borzenkov 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

Also fix memory leak in failure case in grub_diskfilter_make_raid.

Andrei Borzenkov 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.
