+Subject: hrtimers: Push pending hrtimers away from outgoing CPU earlier
+
+From: Thomas Gleixner <tglx@linutronix.de>
+
+[ Upstream commit 5c0930ccaad5a74d74e8b18b648c5eb21ed2fe94 ]
+
+2b8272ff4a70 ("cpu/hotplug: Prevent self deadlock on CPU hot-unplug")
+solved the straight forward CPU hotplug deadlock vs. the scheduler
+bandwidth timer. Yu discovered a more involved variant where a task which
+has a bandwidth timer started on the outgoing CPU holds a lock and then
+gets throttled. If the lock required by one of the CPU hotplug callbacks
+the hotplug operation deadlocks because the unthrottling timer event is not
+handled on the dying CPU and can only be recovered once the control CPU
+reaches the hotplug state which pulls the pending hrtimers from the dead
+CPU.
+
+Solve this by pushing the hrtimers away from the dying CPU in the dying
+callbacks. Nothing can queue a hrtimer on the dying CPU at that point because
+all other CPUs spin in stop_machine() with interrupts disabled and once the
+operation is finished the CPU is marked offline.

+It results in a memory leak.
+
+Instead, only the pointer should be copied.

+Subject: netfilter: ipset: fix race condition between swap/destroy and kernel
+ side add/del/test
+
+From: Jozsef Kadlecsik <kadlec@netfilter.org>
+
+[ Upstream commit 28628fa952fefc7f2072ce6e8016968cc452b1ba ]
+
+Linkui Xiao reported that there's a race condition when ipset swap and destroy is
+called, which can lead to crash in add/del/test element operations. Swap then
+destroy are usual operations to replace a set with another one in a production
+system. The issue can in some cases be reproduced with the script:
+
+ipset create hash_ip1 hash:net family inet hashsize 1024 maxelem 1048576
+ipset add hash_ip1 172.20.0.0/16
+ipset add hash_ip1 192.168.0.0/16
+iptables -A INPUT -m set --match-set hash_ip1 src -j ACCEPT
+while [ 1 ]
+do
+ # ... Ongoing traffic...
+ ipset create hash_ip2 hash:net family inet hashsize 1024 maxelem 1048576
+ ipset add hash_ip2 172.20.0.0/16
+ ipset swap hash_ip1 hash_ip2
+ ipset destroy hash_ip2
+ sleep 0.05
+done
+
+In the race case the possible order of the operations are
+
+ CPU0 CPU1
+ ip_set_test
+ ipset swap hash_ip1 hash_ip2
+ ipset destroy hash_ip2
+ hash_net_kadt
+
+Swap replaces hash_ip1 with hash_ip2 and then destroy removes hash_ip2 which
+is the original hash_ip1. ip_set_test was called on hash_ip1 and because destroy
+removed it, hash_net_kadt crashes.
+
+The fix is to force ip_set_swap() to wait for all readers to finish accessing the
+old set pointers by calling synchronize_rcu().
+
+The first version of the patch was written by Linkui Xiao <xiaolinkui@kylinos.cn>.
+
+v2: synchronize_rcu() is moved into ip_set_swap() in order not to burden
+ ip_set_destroy() unnecessarily when all sets are destroyed.
+v3: Florian Westphal pointed out that all netfilter hooks run with rcu_read_lock() held
+ and em_ipset.c wraps the entire ip_set_test() in rcu read lock/unlock pair.
+ So there's no need to extend the rcu read locked area in ipset itself.
