[dpdk-dev] [PATCH] vhost: return -EAGAIN during unregistering vhost if it is busy.

use of the vhost fd, then leads to deadlock. It is better to return -EAGAIN to application, who will decide how to handle (eg OVS can call ovsrcu_quiesce() and then retry). Signed-off-by: Zhike Wang --- lib/librte_vhost/rte_vhost.h | 4 +++- lib/librte_vhost/socket.c| 8 2 files c

[dpdk-dev] [PATCH] vhost:fix crash on port deletion and VM shutdown at same time

will access invalid memory when trying to reconnect. The fix is to move the "removing of vsocket from conn_list" to end of the vhost_user_read_cb(), then avoid the race condition. The core trace is Program terminated with signal 11, Segmentation fault. Signed-off-by: Zhike Wang

X722 SFPs have different flavors, eg I40E_DEV_ID_SFP_X722 /I40E_DEV_ID_SFP_I_X722. So instead we use mac.type to judge whether it is X722 or not. Fixes: 9efa8d28b ("net/i40e: fix SFP X722 with FW4.16") Signed-off-by: Zhike Wang --- drivers/net/i40e/i40e_ethdev.c | 2 +- 1 file

, the rcb, such as vhost_user_read_cb() would try to retrieve the conn_mutex. So issue is that the 1st thread will loop check the flag while holding the mutex, while the 2nd thread would be blocked by mutex and can not change the flag. Then dead lock is observed. Signed-off-by: zhike wang
