netlink: add reference of module in netlink_dump_start
[ Upstream commit 6dc878a8ca39e93f70c42f3dd7260bde10c1e0f1 ]
I get a panic when I use ss -a and rmmod inet_diag at the
same time.
It's because netlink_dump uses inet_diag_dump which belongs to module
inet_diag.
I search the codes and find many modules have the same problem. We
need to add a reference to the module which the cb->dump belongs to.
Thanks for all help from Stephen,Jan,Eric,Steffen and Pablo.
Change From v3:
change netlink_dump_start to inline,suggestion from Pablo and
Eric.
Change From v2:
delete netlink_dump_done,and call module_put in netlink_dump
and netlink_sock_destruct.
