Bug ID: 1089
Summary: mlx5 Windows crash creating flows in multiple threads
Product: DPDK
Version: 21.11
Hardware: All
OS: Windows
Status: UNCONFIRMED
Severity: critical
Priority: Normal
Component: ethdev
Assignee: dev@dpdk.org
Reporter: paul203...@gmail.com
Target Milestone: ---
Hi,
I am using release 21.11 on Windows with a ConnectX-4 card. My application is
crashing when calling rte_flow_create in two threads at the same time.
I tracked the issue down to mlx5_is_thread_alive() in
drivers/net/mlx5/windows/mlx5_flow_os.c. This is always returning false.
Changing the second return statement to return true fixes the crash.
I think one thread was destroying data structures still in use by another
thread.
