Currenly, quic_conn on the backend side may access their parent proxy instance during their lifetime. In particular, this is the case for counters update, with <prx_counters> field directly referencing a proxy memory zone. As such, this prevents safe backend removal. One solution would be to check if the upper connection instance is still alive, as a proxy cannot be removed if connection are still active. However, this would completely prevent proxy counters update via quic_conn_prx_cntrs_update(), as this is performed on quic_conn release. Another solution would be to use refcount, or a dedicated counter on the which account for QUIC connections on a backend instance. However, refcount is currently only used by short-term references, and it could also have a negative impact on performance. Thus, the simplest solution for now is to disable a backend removal if a QUIC server is/was used in it. This is considered acceptable for now as QUIC on the backend side is experimental. |
