Subject: [PATCH 2/2] fix qemu-core when vhost-user-net config with server mode
|
|
|
|
commit 3a223111d7 set default reconnect for vhost-user-net
|
|
device, if vhost-user-net config with server mode will
|
|
casuse the core when ovs client stop.
|
|
tcp_chr_disconnect ---> set tcp_char state disconnect
|
|
tcp_chr start reconnect ---> set tcp_char state connecting
|
|
tcp_char is listen ---> call tcp_chr_accept()
|
|
fun tcp_char_accept() set tcp_char state to connecting, but
|
|
current tcp_char state already is connecting, assert failed
|
|
in tcp_char_change_state() raise qemu core
|
|
assert(s->state == TCP_CHARDEV_STATE_DISCONNECTED)
|
|
|
|
this commit check tcp_char mode, if tcp_char config with server
|
|
mode, dont set reconnect time for tcp_chr.
