Jeremy Sowden 6be8e297f9 lapb: fixed leak of control-blocks. ... lapb_register calls lapb_create_cb, which initializes the control- block's ref-count to one, and __lapb_insert_cb, which increments it when adding the new block to the list of blocks. lapb_unregister calls __lapb_remove_cb, which decrements the ref-count when removing control-block from the list of blocks, and calls lapb_put itself to decrement the ref-count before returning. However, lapb_unregister also calls __lapb_devtostruct to look up the right control-block for the given net_device, and __lapb_devtostruct also bumps the ref-count, which means that when lapb_unregister returns the ref-count is still 1 and the control-block is leaked. Call lapb_put after __lapb_devtostruct to fix leak. Reported-by: syzbot+afb980676c836b4a0afa@syzkaller.appspotmail.com Signed-off-by: Jeremy Sowden <jeremy@azazel.net> Signed-off-by: David S.
