[Opensc-devel] [minidriver] container naming convention

[Vincent Le T. <vin...@my...>]

I'm working on the minidriver read/write mode and especially the
certificate enrollment process.

When a container is created on the minidriver, there is 3 ways to create
the container:
1)
cf
https://github.com/OpenSC/OpenSC/blob/master/src/minidriver/minidriver.c#L1925
if md_is_guid_as_id = true; the microsoft container name is used as the id

2)
cf
https://github.com/OpenSC/OpenSC/blob/master/src/minidriver/minidriver.c#L1936
if
md_is_guid_as_label = true; the microsoft container name is used as the
label

3) (default)
cf
https://github.com/OpenSC/OpenSC/blob/master/src/minidriver/minidriver.c#L1868
the card is created with the default label "TODO: key label"
(the microsoft container name is not used)

The problem is that when the container is loaded:
1) if the container name is set on the card
cf
https://github.com/OpenSC/OpenSC/blob/master/src/minidriver/minidriver.c#L1501
Note: I didn't find in the code a place where the container name is
initialized

2) (default)
cf
https://github.com/OpenSC/OpenSC/blob/master/src/minidriver/minidriver.c#L1517
a guid is created => the initial container name is not found anymore

=> when the container is created in a process, then reloaded, it fails
because the container name is different


There are many ways to solve this problem:
A) replace the "TODO key label" with a guid and use a conversion table
stored statically.
This way, the guid for 2) is replaced at the load time
B) set md_is_guid_as_label as default for the read write card and keep the
current way to the read only cards
....

Can you give your opinion on this ?
(the history about that, ...)
