Description
In the Linux kernel, the following vulnerability has been resolved:
net_sched: sch_sfq: fix a potential crash on gso_skb handling
SFQ has an assumption of always being able to queue at least one packet.
However, after the blamed commit, sch->q.len can be inflated by packets
in sch->gso_skb, and an enqueue() on an empty SFQ qdisc can be followed
by an immediate drop.
Fix sfq_drop() to properly clear q->tail in this situation.
