Hi Guna, I am looking at it, but don't have much time to spend at it right now. A further study of your dump makes me believe this is a case of race between tipc_recv_stream(), which in user context is setting the "owned" flag but not grabbing slock, and tipc_sk_timeout(), which in interrupt mode is grabbing slock without checking the "owned" flag. This creates an obvious risk of a race, but I don't yet understand the exact implications or solution to it. It may be that it is sufficient to just replace the grabbing of slock with a call to lock_sock() in the timer function as I first suggested, but I rather believe we have to explicitly grab both slock and the flag and keep them for the duration of the timeout, before tipc_node_xmit_skb(). This will protect the timeout against interference from both user context (tipc_recv_stream() and other sw interrups (tipc_sk_rcv()) and vice versa. Or maybe not even this is enough?
I will continue my analysis, but input from others would be appreciated. ///jon > -----Original Message----- > From: GUNA [mailto:gbala...@gmail.com] > Sent: Saturday, 28 May, 2016 06:00 > To: Jon Maloy; tipc-discussion@lists.sourceforge.net; Erik Hugne > Subject: Re: [tipc-discussion] tipc_sk_rcv: Kernel panic on one of the card > on 4.4.0 > > Any update on the issue?
