Hi Igor,
Thank you for your help to review my changes.
> And it will be blocked by our IPMI call.
I see your point. So, BIOS should never be the person to shutdown credential service because BIOS always get executed prior to OS, right?
> Should it be configured with some PCD? Maybe user may select in Setup what method should be used? Or it could be build time configuration?
I have below assumption while I implemented the library. I admit this is not always true.
No Auth: I think this is rare case for Redfish service which gives anonymous privilege to change BIOS settings.
Basic Auth: this is the authentication method which uses username and password to build base64 encoded string.
Session Auth: I assume that client must have a session token first and then use this authentication method. Can we use username and password to generate session token on our own? If my memory serves me correctly, client has to do a login with username and password first and then client can receive session token from server.
If we really like to know what authentication method that Redfish service used, we can issue a HTTP query to "/redfish/v1/Systems" with "No Auth". Then we can know what authentication method is required by reading the "WWW-Authenticate " filed in returned HTTP header.
Thanks,
Nickle

Hi Nickle,
I would like to discuss that DisableBootstrapControl flag and how it is used in our implementation.
According to Redfish HI specification we can use this flag to disable credential bootstrapping control.
It can be disabled permanently or till next reboot of the host or service. That depend on the EnableAfterReset setting on BMC side:
CredentialBootstrapping (v1.3+)
{ object The credential bootstrapping settings for this interface.
EnableAfterReset (v1.3+) Boolean read-write (null) An indication of whether credential bootstrapping is enabled after a reset for this interface.
Enabled (v1.3+) Boolean read-write (null) An indication of whether credential bootstrapping is enabled for this interface.
RoleId (v1.3+) string read-write The role used for the bootstrap account created for this interface.
}
So, if EnableAfterReset set to false, that means BMC will response with 0x80 error and will not return any credentials after reboot. And BIOS BMC communication will fail.
Another concern with disabling credential bootstrapping control is that we do it on Exit Boot event before passing a control to OS.
But OS may also need to communicate to BMC through Redfish Host Interface to post some information. And it will be blocked by our IPMI call.
We create that SMBIOS Type 42 table with Redfish Host Interface settings which can be used by OS to communicate with BMC. But without the credentials it will not be possible.
Another question is AuthMethod parameter you initialize in this library:
*AuthMethod = AuthMethodHttpBasic;
According to Redfish HI specification 3 methods may be used - No Auth, Basic Auth and Session Auth.
Basic Auth and Session Auth methods are required the credentials to be used by BIOS. And both of them should be supported by BMC.
And your high level function RedfishCreateLibredfishService also supports of creation Basic or Session Auth service.
I'm not sure why low level library which is created to get credentials from BMC should decide what Authentication method should be used?
Should it be configured with some PCD? Maybe user may select in Setup what method should be used? Or it could be build time configuration?
Thank you,
Igor

[Chang, Abner]
Allocation memory with the size (USERNAME_MAX_LENGTH + 1) for both BootUsername and BootstrapPassword? Because the maximum number of characters defined in the spec is USERNAME_MAX_LENGTH for the user/password.
Yes, the additional one byte is for NULL terminator. USERNAME_MAX_LENGTH is defined as 16 and follow host interface specification.

Nickle

Could we name this library RedfishPlatformCredentialIpmi so the naming style is consistent with RedfishPlatformCredentialNull?

Could you please add a comment to the reference of IpmiFeaturePkg? We have to give customers a notice that the dependence of "edk2-platforms/Features/Intel/OutOfBandManagement/". They have to add the path to PACKAGES_PATH. You also have to skip this dependence in the RedfishPkg.yaml to avoid the CI error.
Another thing is I propose to move out IpmiFeaturePkg from edk2-platforms/Features/Intel/OutOfBandManagement to edk2-platforms/Features/ManageabilityPkg that also provides the implementation of PLDM/MCTP/IPMI/KCS. I had an initial talk with IpmiFeaturePkg owner and get the positive response on this proposal. I will kick off the discussion on the dev mailing list. That is to say this module may need a little bit change later, however that is good to me having this implementation now.
Thanks
