Each quic_conn are attached in a global thread-local quic_conns list used for "show quic" command. During thread rebinding, a connection is detached from its local list instance and moved to its new thread list. However this operation is not thread-safe and may cause a race condition. To fix this, only remove the connection from its list inside qc_set_tid_affinity(). The connection is inserted only after in qc_finalize_affinity_rebind() on the new thread instance thus prevented a race condition. One impact of this is that a connection will be invisible during rebinding for "show quic". A connection must not transition to closing state in between this two steps or else cleanup via quic_handle_stopping() may not miss it. To ensure this, this patch relies on the previous commit : commit d6646dddccb1aae08f60717b5b6743c513c37299 MINOR: quic: finalize affinity change as soon as possible This should be backported up to 2.7.
