[U-Boot] [PATCH v3 0/6] solve issues in gpt management

[U-Boot] [PATCH v3 0/6] solve issues in gpt management

[Patrick Delaunay]

in the last version v2017.09, I see some regression for the command

$> gpt write mmc 0 "name=test,start=0x4400,size=0"
$> gpt write mmc 0 "name=test,size=0"

I use sandbox python test to verify if this issue is also present in
v2017.11-rc1 and when I check the log tests, I detect a other issue
for the swap / rename feature : the offset and the size is always 1MB
align, that cause issue if the partition wasn't initially 1MB align.
And it is the case of the test (the size of partition change after the
command gpt rename or swap)

I propose this patch-set with:
- updated gpt test to highlight the issues
- my proposed correction for the 2 issues

tests are ok on v2017.11-rc1


Changes in v3:
- update after Stephen Warren comments
- Add partition name in persistent data and test them
- split test_gpt.py update: commit to add the test write command
- tests are now OK for each commit
- Indicate LBA end error for rename command in test/py and commit message

Changes in v2:
- Split test to functional change

[U-Boot] [PATCH v3 1/6] test/py: gpt: copy persistent file

[Patrick Delaunay]

copy the persistent gpt binary file as it can be modified during the test
that avoid issue if the test fail: the test always restart with clean file

[U-Boot] [PATCH v3 3/6] disk: efi: correct the overlap check on GPT header and PTE

[Patrick Delaunay]

[-- Warning: decoded text below may be mangled, UTF-8 assumed --]
[-- Attachment #1: Type: text/plain; charset="windows-1254", Size: 1832 bytes --]

the partition starting at 0x4400 is refused with overlap error:
  $> gpt write mmc 0 "name=test,start=0x4400,size=0"
  Writing GPT: Partition overlap
  error!

even if the 0x4400 is the first available offset for LBA35 with default
value:
- MBR=LBA1
- GPT header=LBA2
- PTE= 32 LBAs (128 entry), 3 to 34

And the command to have one partition for all the disk failed also :
  $> gpt write mmc 0 "name=test,size=0"

After the patch :

  $> gpt write mmc 0 "name=test,size=0"
  Writing GPT: success!
  $> part list mmc 0

  Partition Map for MMC device 0  --   Partition Type: EFI

  Part	Start LBA	End LBA		Name
	Attributes
	Type GUID
	Partition GUID
  1	0x00000022	0x01ce9fde	"test"
	attrs:	0x0000000000000000
	type:	ebd0a0a2-b9e5-4433-87c0-68b6b72699c7
	type:	data
	guid:	b4b84b8a-04e3-4000-0036-aff5c9c495b1

And 0x22 = 34 LBA => offset = 0x4400 is accepted as expected

[U-Boot] [PATCH v3 5/6] test/py: gpt: test start LBA for sub-command rename and swap

[Patrick Delaunay]

Add test of first and last LBA in gpt for rename and swap.
Only the name is expected to change, so test 3 columns
for part command
1: first LBA (start)
2: last LBA (end)
3: partition name

After rename, the last LBA change and it is a error in current U-Boot code
+ "first" = 0x7ff : invalid value (<start)
+ "second" = 0x17ff => size increasing !

Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>

Before rename
0x00000800  0x00000a00      "part1"
0x00001000  0x00001200      "part2"

And after rename last LBA are invalid
0x00000800	0x000007ff "first"
0x00001000	0x000017ff	"second"

this issue will be corrected in next commit of the patchset

[U-Boot] [PATCH v3 6/6] cmd: gpt: solve issue for swap and rename command

[Patrick Delaunay]

don't use prettyprint_part_size() in create_gpt_partitions_list()
that avoid to align offset and size to 1 MiB and increase precision for
start and size.
This patch avoid the risk to change partition size and lost data during

If you're looking for more things to change(!), perhaps change the 
sgdisk commands so that the partitions are big enough that 'gpt read 
host 0' says something other than 'size 0MiB' for the partitions; when I 
saw that, I was initially rather confused until I realized that the 
partitions were less than 1MiB!

I don't really looking...
but I agree: size 0MiB is confusing, I had the same reaction the first time.

So I will propose something when this serie will be accepted,
just update the test to have 2 partitions with different size and > 1MiB.
