only resend established pfcp sessions on reassociation #63

Closed spencersevilla closed 1 year ago

spencersevilla commented 1 year ago

Right now, when PFCP reassociates a CPS (sgwc or smf) with UPS (sgwu or upf), the CPS re-sends a CSR for all PFCP sessions it has associated with the UPS, including any sessions that were in the middle of being established or torn down. This is a simple fix to ensure that it only re-sends requests for any active (already fully established) sessions.
