Peilin Ye 84ad0af0bc net/sched: qdisc_destroy() old ingress and clsact Qdiscs before grafting 
mini_Qdisc_pair::p_miniq is a double pointer to mini_Qdisc, initialized
in ingress_init() to point to net_device::miniq_ingress.  ingress Qdiscs
access this per-net_device pointer in mini_qdisc_pair_swap().  Similar
for clsact Qdiscs and miniq_egress.

Unfortunately, after introducing RTNL-unlocked RTM_{NEW,DEL,GET}TFILTER
requests (thanks Hillf Danton for the hint), when replacing ingress or
clsact Qdiscs, for example, the old Qdisc ("@old") could access the same
miniq_{in,e}gress pointer(s) concurrently with the new Qdisc ("@new"),
causing race conditions [1] including a use-after-free bug in
mini_qdisc_pair_swap() reported by syzbot:

@old and @new should not affect each other.  In other words, @old should
never modify miniq_{in,e}gress after @new, and @new should not update
@old's RCU state.

Fixing without changing sch_api.c turned out to be difficult (please
refer to Closes: for discussions).  Instead, make sure @new's first call
always happen after @old's last call (in {ingress,clsact}_destroy()) has
finished:

In qdisc_graft(), return -EBUSY if @old has any ongoing filter requests,
and call qdisc_destroy() for @old before grafting @new.

Introduce qdisc_refcount_dec_if_one() as the counterpart of
qdisc_refcount_inc_nz() used for filter requests.  Introduce a
non-static version of qdisc_destroy() that does a TCQ_F_BUILTIN check,
just like qdisc_put() etc.

Depends on patch "net/sched: Refactor qdisc_graft() for ingress and
clsact Qdiscs".

[1] To illustrate, the syzkaller reproducer adds ingress Qdiscs under
TC_H_ROOT (no longer possible after commit c7cfbd1150 ("net/sched:
sch_ingress: Only create under TC_H_INGRESS")) on eth0 that has 8
transmission queues:

  Thread 1 creates ingress Qdisc A (containing mini Qdisc a1 and a2),
  then adds a flower filter X to A.

  Thread 2 creates another ingress Qdisc B (containing mini Qdisc b1 and
  b2) to replace A, then adds a flower filter Y to B.

           ...                                 ...

Here, B calls mini_qdisc_pair_swap(), pointing eth0->miniq_ingress to
its mini Qdisc, b1.  Then, A calls mini_qdisc_pair_swap() again during
ingress_destroy(), setting eth0->miniq_ingress to NULL, so ingress
packets on eth0 will not find filter Y in sch_handle_ingress().

This is just one of the possible consequences of concurrently accessing
miniq_{in,e}gress pointers.
