REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3845
Enables KVM and One Click Recovery WLAN capability with WiFi Profile
Sync feature and protocol. Adding WiFiProfileSyncProtocol, which
supports the profilesync driver operations for transferring WiFi profiles
from AMT to the Supplicant. WiFiConnectionManager will check for the
WifiProfileSyncProtocol and if found will operate on the premise of a
One Click Recovery, or KVM flow with a Wifi profile provided by AMT.

I don't understand this change, StrLen returns the length of a Null-terminated Unicode string, it means "Profile->Password[StrLen (Profile->Password)]" should always be 0. Did you see exceptional case?

Yes this is checking if the users entered password had a terminator on the end, if it doesn't we are adding it.
During dev and testing we found a failure case if this was not tested and fixed.

I don't understand this change, StrLen returns the length of a Null-terminated Unicode string, it means "Profile->Password[StrLen (Profile->Password)]" should always be 0. Did you see exceptional case?

> Subject: [edk2-devel] [PATCH] NetworkPkg: Add WiFi profile sync
> protocol support
>
> From: Zachary Clark-Williams <zclarkw112@gmail.com>
>
> REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3845
>
> Enables KVM and One Click Recovery WLAN capability with WiFi Profile
> Sync feature and protocol. Adding WiFiProfileSyncProtocol, which
> supports the profilesync driver operations for transferring WiFi
> profiles from AMT to the Supplicant. WiFiConnectionManager will check
> for the WifiProfileSyncProtocol and if found will operate on the
> premise of a One Click Recovery, or KVM flow with a Wifi profile provided by AMT.

No. StrLen() works by scanning the string until it finds a L'\0'
terminator. Your code is provably wrong.
I would suggest that you retest, and find the mistake in your testing
process.

After reviewing the code that provides the password from AMT to the connection manager, in a later revision after this line was added, the password is assigned a null terminator in its conversion.
Meaning, these lines are no longer necessary.
I will update the patch and resend for submission.
Please feel free to review the rest of this patch in the mean time and provide feedback of any other misalignments to be changed.
Thanks,
Zack
