[LU-13471] LNet: discovery can glitch

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.14.0, Lustre 2.12.6
• Severity: 3

Description

When discovery is initiated from a MR node to another MR peer, we will send the GET message from source NID-A, but the PUSH message from source NID-B. The PUSH will not be recognize because the peer doesn't have any record of NID-B yet and will drop the push. This will result in asymmetric information. The MR node will have a record for the peer NIDs, but the peer will not have a record of the node's NIDs.
