qc_check_dcid() is a function which check that a DCID is associated to the expected quic_conn instance. This is used for quic_conn socket receive handler as there is a tiny risk that a datagram to another connection was received on this socket. As other operations on global CID tree, a lock must be used to protect against race condition. However, as previous commit, lock was not held long enough as CID tree node is accessed outside of the lock region. To fix this, increase critical section until CID dereferencement is done. The impact of this bug should be similar to the previous one. However, risk of crash are even less reduced as it should be extremely rare to receive datagram for other connections on a quic_conn socket. As such, most of the time first check condition of qc_check_dcid() is enough. This may fix first crash of issue github #2607. This must be backported up to 2.8. |
