2021-04-26session: fix race condition in fifo allocationliuyacan1-1/+1
Under some timing conditions,VCL may receive CONNECTED/ACCEPTED event before ADD_SEGMENT event. Timing example: 2 threads call segment_manager_alloc_session_fifos() parallelly Thread 1 Thread 2 sm read lock | | | try to alloc fifo =>failed | | | sm read unlock | | | sm write lock | | | add segment | | | sm write unlock | | sm read lock | | | try to alloc fifo=>successful sm read lock | | sm read unlock | | | emit CONNECTED/ACCEPTED emit ADD_SEGMENT event | sm read unlock This commit move ADD_SEGMENT notification under the protection of the write lock in some scenarios.
