Add new quote module (src/migtd/src/quote.rs) that centralizes TD quote generation with exponential backoff retry (5s initial, up to 5 retries). This handles the race where an impactless security update invalidates a TD REPORT generated before the update then sent for quote generation. Replace direct attestation::get_quote + tdcall_report calls with quote::get_quote_with_retry in three call sites: - mig_policy.rs: local TCB info initialization - ratls/server_client.rs: RA-TLS quote generation - spdm/mod.rs: SPDM quote generation, also changed error return to MigrationAttestationError for failed quote generation, consistent with RA-TLS.

Also flush log area in more VMCALL handlers so all logs read in time Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Signed-off-by: Haitao Huang <haitaohuang@microsoft.com>
Adds a new 'Mock Quote Retry' test that exercises the quote retry logic by enabling mock_quote_retry feature. The test verifies: - Migration completes successfully after 8 simulated quote failures - Both source and destination logs contain exactly 8 retry failures and at least 1 success message Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Signed-off-by: Haitao Huang <haitaohuang@microsoft.com>
