TSAN: fix races in udp channels #1873

commented Mar 28, 2019

TSAN reported races in socket usage as well as unlocked access to the channels container in max_ip_connections

The call to channels.socket.async_send_to has been encapsulated in udp_channels (so the caller doesn't have to know about the mutex)
