Description

In the Linux kernel, the following vulnerability has been resolved: ipvs: do not propagate one-packet flag to synced conns Synced connections can be created before their destination exists. When the destination is later added, ip_vs_bind_dest() copies connection flags from the destination into cp->flags. IP_VS_CONN_F_ONE_PACKET connections are not synced. If a synced connection inherits IP_VS_CONN_F_ONE_PACKET while it is already hashed, expiry can treat it as a one-packet connection and skip unlinking the existing conn_tab node, leaving stale hash nodes pointing at a freed struct ip_vs_conn. Drop IP_VS_CONN_F_ONE_PACKET from destination flags when binding synced connections.
