Matching subscriptions: iproute2 https://bugs.launchpad.net/bugs/1642514 Title: sched: Match-all classifier is missing in xenial Status in iproute2 package in Ubuntu: Fix Released Status in linux package in Ubuntu: Fix Released Status in iproute2 source package in Xenial: Fix Committed Status in linux source package in Xenial: Fix Released Bug description: [SRU Justification] == Impact == The Xenial 4.4 kernel already has a patch applied which implements the matchall filter. But in order to actually use it, iproute2 needs to pick up the user-space side of the implementation. == Fix == Backported a patch from iproute2 upstream which adds the missing support. Tested against the standard 4.4 and the HWE kernel in 16.04 (see testcase). == Risk of Regression == This adds a new filter type which has to be actively selected. This should not impact existing uses. So low. == Testcase == ip link add dev dummy0 type dummy ip link add dev dummy1 type dummy ip link set dev dummy0 up ip link set dev dummy1 up tc qdisc add dev dummy0 handle 1: root prio tc filter add dev dummy0 parent 1: matchall skip_hw action mirred egress mirror dev dummy1 at this point, "tc filter show dev dummy0" should spit out something like: filter parent 1: protocol all pref 49152 matchall filter parent 1: protocol all pref 49152 matchall handle 0x1 action order 1: mirred (Egress Mirror to device dummy1) pipe index 1 ref 1 bind 1 and the functionality can be tested via tcpdump -n -i dummy1 & ping -I dummy0 1.2.3.4 --- This is implemented in linux v4.8 by the following upstream patch: bf3994d2ed31 ("net/sched: introduce Match-all classifier") http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=bf3994d2ed31 The backport is straightforward. It's useful in combination with clsact qdisc (see bug #1642510).
