global: Convert simple_strtoul() with decimal to dectoul()

2021-08-02T17:32:14+00:00

It is a pain to have to specify the value 10 in each call. Add a new
dectoul() function and update the code to use it.

global: Convert simple_strtoul() with hex to hextoul()

2021-08-02T17:32:14+00:00

It is a pain to have to specify the value 16 in each call. Add a new
hextoul() function and update the code to use it.

Add a proper comment to simple_strtoul() while we are here.

disk: Tidy up #ifdefs in part_efi

2021-07-28T18:27:54+00:00

This file does not correctly handle the various cases, sometimes
producing warnings about partition_basic_data_guid being defined but not
used. Fix it.

There was some discussion about adjusting Kconfig or making
HAVE_BLOCK_DEVICE a prerequisite for PARTITIONS, but apparently this is
not feasible. Such changes can be undertaken separate from the goal of
this series.

disk/part_dos.c: Fix a variable typo in write_mbr_partitions()

2021-06-22T17:58:08+00:00

This function is passed *dev not *dev_desc, so pass the right name to
part_init().

part: Add check for NULL dev_part_str

2021-05-26T21:26:07+00:00

Some callers (e.g. cmd/fs.c) of fs_set_blk_dev may use a NULL dev_part_str.
While blk_get_device_part_str handles this fine,
part_get_info_by_dev_and_name does not. This fixes commands crashing when
implicitly using bootdevice.

The unit test has also been updated to set bootdevice to a known value and
to restore it after we are done.

Fixes: 7194527b6a ("cmd: fs: Use part_get_info_by_dev_and_name_or_num to parse partitions")

part: Fix bogus return from part_get_info_by_dev_and_name

2021-04-22T18:09:45+00:00

blk_get_device_by_str returns the device number on success. So we must
check if the return was negative to determine an error.

disk: gpt: verify alternate LBA points to last usable LBA

2021-04-12T21:17:11+00:00

The gpt command require the GPT backup header at the standard location
at the end of the device. Check the alternate LBA value before reading
the GPT backup header from the last usable LBA of the device.

part: Support string block devices in part_get_info_by_dev_and_name

2021-02-26T14:30:55+00:00

This adds support for things like "#partname" and "0.1#partname". The block
device parsing is done like in blk_get_device_part_str.

part: Support getting whole disk from part_get_info_by_dev_and_name_or_num

2021-02-26T14:30:55+00:00

This adds an option to part_get_info_by_dev_and_name_or_num to allow
callers to specify whether whole-disk partitions are fine.

part: Give several functions more useful return values

2021-02-26T14:30:55+00:00

Several functions in disk/part.c just return -1 on error. This makes them
return different errnos for different failures. This helps callers
differentiate between failures, even if they cannot read stdout.
