It was reported by Husaini that since commit 1461d212ab27 ("net/sched:
taprio: make qdisc_leaf() see the per-netdev-queue pfifo child
qdiscs"), there was a NULL dereference when adding a child qdisc (ETF
in this case) when using taprio full offload.
The issue seems to be that since commit 13511704f8d7 ("net: taprio
offload: enforce qdisc to netdev queue mapping"), the array of child
qdiscs (q->qdiscs[]) was not used, and even free'd when full offload
mode is used, in attach().
The current implementation since 1461d212ab27 (which I feel is a
sensible change) requires that the q->qdiscs[] array is always valid.
The fix is to not deallocate it, and keep it having references to each
child qdisc.

This patch is more to make others aware of this issue and to explain
what I think is going on. Perhaps the correct solution is something
else. (and that explicit refcount seems wrong, but getting warnings
without it).
I am questioning my sanity, I have clear memories about testing the
commit above and it working fine.
Reverting commit 1461d212ab27 is another alternative, but I think it's
worth to keep that and fix the problem that it exposed.

I studied the problem a bit and unfortunately your fix is not correct.
It is not sufficient to call qdisc_refcount_inc() on the child qdiscs
grafted in taprio_graft(), there are still other sources of use-after-free.
I will send a revert of my patch soon, and explain there in more detail
what the problem is. Sorry for the trouble and thanks for reporting the
problem and proposing a solution.

I was afraid that this this would happen. I need to stop, grab some tea
and think very carefully how to simplify the lifetime handling of the
children qdiscs. It has become complicated now that the
offloaded/not-offloaded modes are very different internally.

Agreed. The revert is safer for net.
No worries. Been there, done that.

Truth be told, it's not like the problem Yannick described in commit
13511704f8d7 ("net: taprio offload: enforce qdisc to netdev queue
mapping") is unique only to the offloaded taprio, but I just don't know
enough about qdiscs to see a different design than what is currently
implemented.

Hi Vinicius,
I love your patch! Perhaps something to improve:
