Leon Romanovsky 935454915c RDMA/netlink: Fix locking around __ib_get_device_by_index ... [ Upstream commit f8978bd95c ] Holding locks is mandatory when calling __ib_device_get_by_index, otherwise there are races during the list iteration with device removal. Since the locks are static to device.c, __ib_device_get_by_index can never be called correctly by any user out side the file. Make the function static and provide a safe function that gets the correct locks and returns a kref'd pointer. Fix all callers. Fixes: e5c9469efc ("RDMA/netlink: Add nldev device doit implementation") Fixes: c3f66f7b00 ("RDMA/netlink: Implement nldev port doit callback") Fixes: 7d02f605f0 ("RDMA/netlink: Add nldev port dumpit implementation") Reviewed-by: Mark Bloch <markb@mellanox.com> Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com> Signed-off-by: Sasha Levin <alexander.levin@verizon.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		History 2018-03-03 10:24:34 +01:00
