Hi Guna, Please see my comments below.
Regards, Ying -----Original Message----- From: GUNA [mailto:gbala...@gmail.com] Sent: 2016年6月1日 23:26 To: Xue, Ying Cc: Jon Maloy; Jon Maloy; tipc-discussion@lists.sourceforge.net; Erik Hugne; Xue Ying (ying.x...@gmail.com) Subject: Re: [tipc-discussion] tipc_sk_rcv: Kernel panic on one of the card on 4.4.0 If the issue is reproducible then I could try with Erik's patch even though the root cause is unknown. Currently, we are not clear yet on root cause of the issue. I could add the patch on production release, only if the patch will fix the issue. [Ying] Understood your meaning. I think Erik's patch should be merged into upstream whatever it can fix your issue or not. But in my opinion, it should be able to fix it. Otherwise, I may need to find test stream. As per Erik's proposal, ====== if (sock_owned_by_user(sk)) we can reschedule timer for a retry in a few jiffies ====== I tried to call sk_reset_timer(sk, &sk->sk_timer, (HZ / 20)); but the code or similar already is in place at tipc_sk_timeout() as marked by "<<==" below" if (tsk->probing_state == TIPC_CONN_PROBING) { if (!sock_owned_by_user(sk)) ... else sk_reset_timer(sk, &sk->sk_timer, (HZ / 20)); <<== } else { sk_reset_timer(sk, &sk->sk_timer, jiffies + tsk->probing_intv); <<== } Please let me know If I need to add/modify any. [Ying] your change above is right and it should be workable. But I still suggest you should adopt Erik's patch("tipc: fix timer handling when socket is owned ") as it's much better than above solution. thanks, Guna On Wed, Jun 1, 2016 at 7:31 AM, Xue, Ying <ying....@windriver.com> wrote: > Hi GUNA, > > Thanks for your confirmation, which is very important for us to look into > what happened in 4.4.0 version. > Yes, my mentioned Erik's patch is just as Erik said: "tipc: fix timer > handling when socket is owned". > > I also agree to Erik's solution as its change is more common method to deal > with the case when owner flag is not set in BH. > > But now we still need to know what root cause is the issue. > > If possible, please apply Erik's patch on your side to check whether the > issue occurs or not. > > Regards, > Ying > > -----Original Message----- > From: GUNA [mailto:gbala...@gmail.com] > Sent: 2016年5月31日 23:34 > To: Xue, Ying > Cc: Jon Maloy; Jon Maloy; tipc-discussion@lists.sourceforge.net; Erik Hugne; > Xue Ying (ying.x...@gmail.com) > Subject: Re: [tipc-discussion] tipc_sk_rcv: Kernel panic on one of the card > on 4.4.0 > > Just want to clarify, system was upgraded only the kernel from 3.4.2 > to 4.4.0 + some tipc patches on Fedora distribution.
