However, time exceeded messages can either represent "time to live exceeded in transit" (code 0) or "fragment reassembly time exceeded" (code 1). Unconditionally replying to "fragment reassembly time exceeded" with host unreachable messages might cause unjustified connection resets which are now easily triggered as UFO has been removed, because, in turn, sending large buffers triggers IP fragmentation. The issue can be easily reproduced by running a lot of UDP streams which is likely to trigger IP fragmentation: # start netserver in the test namespace ip netns add test ip netns exec test netserver # create a VETH pair ip link add name veth0 type veth peer name veth0 netns test ip link set veth0 up ip -n test link set veth0 up for i in $(seq 20 29); do # assign addresses to both ends ip addr add dev veth0 192.168.$i.1/24 ip -n test addr add dev veth0 192.168.$i.2/24 # start the traffic netperf -L 192.168.$i.1 -H 192.168.$i.2 -t UDP_STREAM -l 0 & done # wait send_data: data send error: No route to host (errno 113) netperf: send_omni: send_data failed: No route to host We need to differentiate instead: if fragment reassembly time exceeded is reported, we need to silently drop the packet, if time to live exceeded is reported, maintain the current behaviour. In both cases increment the related error count "icmpInTimeExcds". While at it, fix a typo in a comment, and convert the if statement into a switch to mate it more readable.

Hence, ingress packets which gets to the RSS QP will be steered then to a garbage QPN. The patch fixes this by skipping the above assignment when a RSS QP is modified, also, the RSS context's attributes assignments are relocated just before the context is posted to avoid future issues like this. Additionally, this patch takes the opportunity to change the code to be disciplined to the device's manual and assigns the RSS QP context just at RESET to INIT transition.

[Linux-stable-mirror] Patch "IB/ipoib: Grab rtnl lock on heavy flush when calling ndo_open/stop" has been added to the 4.14-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled IB/ipoib: Grab rtnl lock on heavy flush when calling ndo_open/stop to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: ib-ipoib-grab-rtnl-lock-on-heavy-flush-when-calling-ndo_open-stop.patch and it can be found in the queue-4.14 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From foo@baz Mon Dec 18 13:29:00 CET 2017 From: Alex Vesker <valex(a)mellanox.com> Date: Tue, 10 Oct 2017 10:36:41 +0300 Subject: IB/ipoib: Grab rtnl lock on heavy flush when calling ndo_open/stop From: Alex Vesker <valex(a)mellanox.com> [ Upstream commit b4b678b06f6eef18bff44a338c01870234db0bc9 ] When ndo_open and ndo_stop are called RTNL lock should be held. In this specific case ipoib_ib_dev_open calls the offloaded ndo_open which re-sets the number of TX queue assuming RTNL lock is held. Since RTNL lock is not held, RTNL assert will fail.
