There is currently no timeout to the resource and lock acquiring loops. We printed warnings and depended on user sending a signal to the waiting process to stop the waiting. This doesn't work very well when wait happens out of a work queue. The simplest example of that is PCI probe. When user loads the module and card is in a broken state modprobe will wait forever and signals sent to it will not actually reach the probing thread. Make sure all wait loops have a time out. Set the upper wait time to 60 seconds to stay on the safe side. Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S. Miller <davem@davemloft.net> |
