[Linux-stable-mirror] Patch "icmp: don't fail on fragment reassembly time exceeded" has been added to the 4.14-stable tree

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.

Such caller might allocate or free memory in callback handler depending on the completion status to make further progress or to terminate a connection. Most ULPs resolve route which involves allocating route entry and path record elements in callback event handler. It has been noticed that WQ_MEM_RECLAIM flag should not be used for workers that tend to allocate memory in this [1] thread discussion. In order to mitigate this situation, WQ_MEM_RECLAIM flag was dropped for other such WQs in this [2] patch. Similar problem might arise with address resolution path, though its not yet noticed. The ib_addr workqueue is not memory reclaim path due to its nature of invoking callback that might allocate memory or don't free any memory under memory pressure.

[Linux-stable-mirror] Patch "GFS2: Take inode off order_write list when setting jdata flag" has been added to the 4.14-stable tree

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 13:28:59 CET 2017 From: Bob Peterson <rpeterso(a)redhat.com> Date: Wed, 20 Sep 2017 08:30:04 -0500 Subject: GFS2: Take inode off order_write list when setting jdata flag From: Bob Peterson <rpeterso(a)redhat.com> [ Upstream commit cc555b09d8c3817aeebda43a14ab67049a5653f7 ] This patch fixes a deadlock caused when the jdata flag is set for inodes that are already on the ordered write list. Since it is on the ordered write list, log_flush calls gfs2_ordered_write which calls filemap_fdatawrite. But since the inode had the jdata flag set, that calls gfs2_jdata_writepages, which tries to start a new transaction. A new transaction cannot be started because it tries to acquire the log_flush rwsem which is already locked by the log flush operation. The bottom line is: We cannot switch an inode from ordered to jdata until we eliminate any ordered data pages (via log flush) or any log_flush operation afterward will create the circular dependency above. So we need to flush the log before setting the diskflags to switch the file mode, then we need to remove the inode from the ordered writes list. Before this patch, the log flush was done for jdata->ordered, but that's wrong. If we're going from jdata to ordered, we don't need to call gfs2_log_flush because the call to filemap_fdatawrite will do it for us: filemap_fdatawrite() -> __filemap_fdatawrite_range() __filemap_fdatawrite_range() -> do_writepages() do_writepages() -> gfs2_jdata_writepages() gfs2_jdata_writepages() -> gfs2_log_flush() This patch modifies function do_gfs2_set_flags so that if a file has its jdata flag set, and it's already on the ordered write list, the log will be flushed and it will be removed from the list before setting the flag.

As explained in commit 5ccc248cc537 ("ARM: imx6q: clk: Add support for mipi_core_cfg clock as a shared clock gate"), video_27m is gated by CCM_CCGR3[CG8]. On i.MX6 SoCs with VPU, the hdmi is working thanks to the CCM_CMEOR[mod_en_ov_vpu] bit which makes the video_27m ungated whatever is in CCM_CCGR3[CG8].
