[Bug 1747970] Re: [Hyper-V] vsock: always call vsock_init_tables()
Yes, I confirm this is the patch we need for the Enhanced Session mode.
The patch was originally made to fix a different issue, but it can also
fix the VM panic we see with Enhanced Session mode, because the cause is
the same: there is a race
static int __init hvs_init(void)
{
int ret;
if (vmbus_proto_version < VERSION_WIN10)
return -ENODEV;
ret = vmbus_driver_register(_drv);
if (ret != 0)
return ret;
Dexuan: ---: if the host-initiated connection comes
here (e.g. before we call vsock_core_init(), hvs_open_connection() ->
vsock_find_bound_socket() -> __vsock_find_bound_socket() can access the
uninitialized vsock_bound_sockets(addr) -> vsock_bind_table, which will be
initialized in vsock_core_init() -> vsock_init_tables(), and we'll hit a panic.
ret = vsock_core_init(_transport);
if (ret) {
vmbus_driver_unregister(_drv);
return ret;
}
return 0;
}
The latest upstream 4.15.1 kernel has the fix already, but 4.14.17 doesn't
have the fix.
