Merge branch 'net-sched-teql-enforce-hierarchy-placement'
Jamal Hadi Salim says:
====================
net/sched: teql: Enforce hierarchy placement
GangMin Kim <km.kim1503@gmail.com> managed to create a UAF on qfq by inserting
teql as a child qdisc and exploiting a qlen sync issue.
teql is not intended to be used as a child qdisc. Lets enforce that rule in
patch #1. Although patch #1 fixes the issue, we prevent another potential qlen
exploit in qfq in patch #2 by enforcing the child's active status is not
determined by inspecting the qlen. In patch #3 we add a tdc test case.
