Hi! This series avoids a potential crash on nfp representor devices when netpoll is in use. If transmitting the frame through underlying vNIC fails we'd return an error code (by passing on error code from __dev_queue_xmit()) and cause double free in netpoll code.
Fix the error code and disable netpoll on reprs altogether. IRQ-safety of locking the queues and calling __dev_queue_xmit() is questionable. Big thanks to John Hurley for debugging and narrowing down the trace log after I gave up! :) Jakub Kicinski (2): nfp: validate the return code from dev_queue_xmit() nfp: disable netpoll on representors drivers/net/ethernet/netronome/nfp/nfp_net_repr.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) -- 2.19.2
