gpt: rename and update documentation for grub_gpt_update
...
The function now does more than just recompute checksums so give it a
more general name to reflect that.

gpt: do not use an enum for status bit values
2018-03-29 22:18:54 -04:00
a794435ae9
gpt: use inline functions for checking status bits
...
This should prevent bugs like 6078f836 and 4268f3da.

gpt: fix partition table indexing and validation
...
Portions of the code attempted to handle the fact that GPT entries on
disk may be larger than the currently defined struct while others
assumed the data could be indexed by the struct size directly. This
never came up because no utility uses a size larger than 128 bytes but
for the sake of safety we need to do this by the spec.

gpt: add search by partition label and uuid commands
...
Builds on the existing filesystem search code. Only for GPT right now.

gpt: switch partition names to a 16 bit type
...
In UEFI/GPT strings are UTF-16 so use a uint16 to make dealing with the
string practical.

gpt: split out checksum recomputation
...
For basic data modifications the full repair function is overkill.
2018-03-29 22:18:52 -04:00

gpt: new gptprio.next command for selecting priority based partitions
...
Basic usage would look something like this:
gptprio.next -d usr_dev -u usr_uuid
linuxefi ($usr_dev)/boot/vmlinuz mount.usr=PARTUUID=$usr_uuid
After booting the system should set the 'successful' bit on the
partition that was used.

gpt: add a new generic GUID type
...
In order to do anything with partition GUIDs they need to be stored in a
proper structure like the partition type GUIDs. Additionally add an
initializer macro to simplify defining both GUID types.
2018-03-29 22:18:52 -04:00
5e1829d414
gpt: add write function and gptrepair command
...
The first hint of something practical, a command that can restore any of
the GPT structures from the alternate location. New test case must run
under QEMU because the loopback device used by the other unit tests does
not support writing.

gpt: add new repair function to sync up primary and backup tables.
2018-03-29 22:18:52 -04:00

gpt: record size of of the entries table
...
The size of the entries table will be needed later when writing it back
to disk. Restructure the entries reading code to flow a little better.
2018-03-29 22:18:52 -04:00
c26743a145
gpt: rename misnamed header location fields
...
The header location fields refer to 'this header' and 'alternate header'
respectively, not 'primary header' and 'backup header'. The previous
field names are backwards for the backup header.
2018-03-29 22:18:52 -04:00

gpt: start new GPT module
...
This module is a new implementation for reading GUID Partition Tables
which is much stricter than the existing part_gpt module and exports GPT
data directly instead of the generic grub_partition structure. It will
be the basis for modules that need to read/write/update GPT data.
The current code does nothing more than read and verify the table.
