Current upstream kernel is booting fine under Xen, so in general the patch should be fine. Using an upstream kernel built from above commit (with the then needed Xen fixup patch 1457d8cf7664f34c4ba534) is fine, too. Kirill, are you aware of any prerequisite patch from 4.20 which could be missing in 4.19.5? Juergen

[PATCH v3] [bug/urgent] dvb-usb-v2: Fix incorrect use of transfer_flags URB_FREE_BUFFER

by Malcolm Priestley

In commit 1a0c10ed7b media: dvb-usb-v2: stop using coherent memory for URBs incorrectly adds URB_FREE_BUFFER after every urb transfer. It cannot use this flag because it reconfigures the URBs accordingly to suit connected devices. In doing a call to usb_free_urb is made and invertedly frees the buffers. The stream buffer should remain constant while driver is up.

Please include d391f120706726826 in v4.9.y [x86/kvm/vmx]: do not use vm-exit instruction length for fast MMIO when running nested

by Mike Haboustak

The following commit fixes freezes in virtio device drivers when KVM is nested under VMWare Workstation/ESXi or Hyper-V. I've encountered problems running KVM inside VMWare since upgrading to Debian 9 (currently testing 4.9.88-1+deb9u1). d391f1207067268261add0485f0f34503539c5b0 The same issue affects 4.4.y as well. A git-bisect within my environment stopped at e9ea5069d9e569c32ab913c39467df32e056b3a7, where the KVM capability was added that QEMU checks before enabling fast mmio. Thanks, Mike

[PATCH v3.16 2/2] v4l: event: Add subscription to list before calling "add" operation

by Sakari Ailus

[ upstream commit 92539d3eda2c090b382699bbb896d4b54e9bdece ] Patch ad608fbcf166 changed how events were subscribed to address an issue elsewhere. As a side effect of that change, the "add" callback was called before the event subscription was added to the list of subscribed events, causing the first event queued by the add callback (and possibly other events arriving soon afterwards) to be lost. Fix this by adding the subscription to the list before calling the "add" callback, and clean up afterwards if that fails.

[PATCH] netfilter: xt_connlimit: fix race in connection counting

by Alakesh Haloi

An iptable rule like the following on a multicore systems will result in accepting more connections than set in the rule. iptables -A INPUT -p tcp -m tcp --syn --dport 7777 -m connlimit \ --connlimit-above 2000 --connlimit-mask 0 -j DROP In check_hlist function, connections that are found in saved connections but not in netfilter conntrack are deleted, assuming that those connections do not exist anymore. But for multi core systems, there exists a small time window, when a connection has been added to the xt_connlimit maintained rb-tree but has not yet made to netfilter conntrack table. This causes concurrent connections to return incorrect counts and go over limit set in iptable rule. Connection 1 on Core 1 Connection 2 on Core 2 list_length = N conntrack_table_len = N spin_lock_bh() In check_hlist() function a. loop over saved connections 1. call nf_conntrack_find_get() 2. If not found in 1, i. call hlist_del() b. return total count to caller c. connection gets added to list of saved connections. spin_unlock_bh() list_length = N + 1 spin_lock_bh() on core 2 In check_hlist() function a. loop over saved connection. 1. call nf_conntrack_find_get() 2. If not found in 1. i. call hlist_del() [Connection 1 was in the but not in nf_conntrack yet] ii. connection 1 gets deleted list_length = N conntrack_table_len = N b. return total count to caller c. connection 2 gets added to list of saved connections spin_unlock_bh() d. connection 1 gets added to nf_conntrack list_length = N + 1 conntrack_table_len = N + 1 e. connection 2 gets added to nf_conntrack list_length = N + 1 conntrack_table_len = N + 2 So we end up with N + 1 connections in the list but N + 2 in nf_conntrack, allowing more number of connections eventually than set in the rule. This fix adds an additional field to track such pending connections and prevent them from being deleted by another execution thread on a different core and returns correct count.

4.14 backport request for dbdda842fe96f: "printk: Add console owner and waiter logic to load balance console writes"

by Daniel Wang

Prior to this change, the combination of `softlockup_panic=1` and `softlockup_all_cpu_stacktrace=1` may result in a deadlock when the reboot path is trying to grab the console lock that is held by the stack trace printing path. What seems to be happening is that while there are multiple CPUs, only one of them is tasked to print the back trace of all CPUs. On a machine with many CPUs and a slow serial console (on Google Compute Engine for example), the stack trace printing routine hits a timeout and the reboot path kicks in. The latter then tries to print something else, but can't get the lock because it's still held by earlier printing path. This is easily reproducible on a VM with 16+ vCPUs on Google Compute Engine - which is a very common scenario. A quick repro is available at https://github.com/wonderfly/printk-deadlock-repro. The system hangs 3 seconds into executing repro.sh. Both deadlock analysis and repro are credits to Peter Feiner. Note that I have read previous discussions on backporting this to stable [1]. The argument for objecting the backport was that this is a non-trivial fix and is supported to prevent hypothetical soft lockups. What we are hitting is a real deadlock, in production, however. Hence this request. [1] https://lore.kernel.org/lkml/20180409081535.dq7p5bfnpvd3xk3t@pathway.suse.c… Serial console logs leading up to the deadlock. As can be seen the stack trace was incomplete because the printing path hit a timeout. ``` lockup-test-16-2 login: [ 206.648060] LoadPin: kernel-module pinning-ignored obj="/tmp/release/hog.ko" pid=3003 cmdline="insmod hog.ko" [ 206.650851] hog: loading out-of-tree module taints kernel.
