This looks wrong to me. IIRC, we should be able to send
ICMP errors from the OUTPUT hook where skb->dev is NULL. It is
true even for IPv6: net/ipv6/netfilter/ip6t_REJECT.c works for
NF_INET_LOCAL_OUT. nf_send_unreach6() and other IPv6 places have
workarounds to avoid skb->dev being NULL but IPv4 and IPv6 are
different: IPv4 never required skb->dev to be non-NULL, so better
do not change that. Just check dst.dev to avoid crash.

Hi David, Heiner,
could you please be specific what to add? The discussion was on various
topics. Agree that it would probably help to add some more clarity, but
it would be good if you can specify your expectation in this.

AF_XDP socket only triggers tx interrupt on ndo_xsk_async_xmit() which
is used in zero-copy mode. Real xmit happens inside
ixgbe_poll()
-> ixgbe_clean_xdp_tx_irq()
-> ixgbe_xmit_zc()
This should be not possible to bound another XDP socket to the same netdev
queue.
It also possible to xmit frames in xdp_ring while performing XDP_TX/REDIRECT
actions. REDIRECT could happen from different netdev with different NAPI
context, but this operation is bound to specific CPU core and each core has
its own xdp_ring.
However, I'm not an expert here.
Björn, maybe you could comment on this?

Checking the number of used descs, i.e. next_to_use - next_to_clean,
makes iteration in this function logically equal to the iteration inside
'ixgbe_xsk_clean_tx_ring()'. Do you think we need to change the later
function too to follow same 'bytecount' approach? I don't like having
two different ways to determine number of used descriptors in the same file.
Best regards, Ilya Maximets.

As you say, C45 doesn't cover 1000BaseT, therefore for this mode a
vendor-specific part is needed in the PHY driver always.
That's the reason why genphy_c45_an_config_aneg is meant to be used
within a PHY drivers config_aneg callback implementation, and why
we don't have a generic C45 config_aneg function yet.
Use case for the new function could be cases where 1000BaseT support
isn't needed, and it could serve as a fallback if there's no
dedicated PHY driver yet e.g. for a new chip.

As far as ixgbe_clean_xdp_tx_irq() vs ixgbe_xsk_clean_tx_ring(), I
would say that if you got rid of budget and framed things more like
how ixgbe_xsk_clean_tx_ring was framed with the ntc != ntu being
obvious I would prefer to see us go that route.
Really there is no need for budget in ixgbe_clean_xdp_tx_irq() if you
are going to be working with a static ntu value since you will only
ever process one iteration through the ring anyway. It might make more
sense if you just went through and got rid of budget and i, and
instead used ntc and ntu like what was done in
ixgbe_xsk_clean_tx_ring().
Thanks.

If no such device is on the market yet, then I'd suggest:
- wait for such a device to see whether genphy_c45 driver is really
sufficient or whether other chip features require a dedicated driver
anyway. In the latter case it may be better to add dedicated T1
functions to phylib.
- add the missing 10BASE-T1L and 10BASE-T1S support meanwhile
The current patch set IMO is a little bit hacky. I'm not 100% happy
with the implicit assumption that there can't be devices supporting
T1 and classic BaseT modes or fiber modes.

Indeed.
I missed "(opened)" part in Documentation/trace/ftrace.rst:
trace:
This file holds the output of the trace in a human
readable format (described below). Note, tracing is temporarily
disabled while this file is being read (opened).
I always thought that reading disables it.
It's indeed odd part of the ftrace implementation that
worth documenting here.
Applied the set to bpf-next. Thanks

Just a quick update on that.
The test case is nginx running with ktls offload.
The client (hurl or openssl client) requests a file of ~2M, but only
44K ever gets across (not even sure which side sees an error at this
point, outputs are pretty quiet).

At first I was confused why you bring up rtnl lock in commit message
(flower classifier has 'unlocked' flag set and can't rely on it anymore)
but looking at the code I see that we lost rcu read lock here in commit
d39d714969cd ("idr: introduce idr_for_each_entry_continue_ul()") and you
are correctly bringing it back. Adding Cong to advise if it is okay to
wait for this patch to be accepted or we need to proceed with fixing the
missing RCU lock as a standalone patch.

What is the motivation for this change? You substitute O(n) iteration
over linked list with O(nlogn) iteration over xarray without any
apparent benefit.

I see, that sounds reasonable, yes. Thanks for clarifying.

The dev_kfree_skb() function performs also input parameter validation.
Thus the test around the shown calls is not needed.
This issue was detected by using the Coccinelle software.

In addition, as long as additional keys still can't be added or

this is fine.

Hi Heiner
I would also like cleaner integration. I doubt here is anything in the
standard which says you cannot combine these modes. It is more a
marketing question if anybody would build such a device. Maybe not
directly into a vehicle, but you could imaging a mobile test device
which uses T1 to talk to the car and T4 to connect to the garage
network?
So i don't think we should limit ourselves. phylib should provide a
clean, simple set of helpers to perform standard operations for
various modes. Drivers can make use of those helpers. That much should
be clear. If we try to make genphy support them all simultaneously, is
less clear.

Jiong,
Thanks for the review. I can now see why the other two changes are not
necessary. I will post a follow-on patch.

I like how xa mark simplifies reoffload handling, but this wouldn't
work anymore because without rtnl protection fl_change()/fl_delete() can
be called concurrently with fl_reoffload(). My original implementation
of unlocked flower classifier relied on idr in fl_reoffload() and we had
to introduce hw_list due to following race conditions:
- fl_reoffload() can miss fnew if it runs after fnew was provisioned to
hardware with fl_hw_replace_filter() but before it is marked with
HW_FILTER.
- Another race condition would be in __fl_delete() when filter is
removed from xarray, then shared block is detached concurrently which
causes fl_reoffload() that misses the filter, then the block callback
is no longer present when fl_hw_destroy_filter() calls
tc_setup_cb_call() and we have a dangling filter that can't be removed
from hardware anymore.
That is why filter must be added to hw_list where it is done now - in
fl_hw*() functions while holding rtnl lock to prevent concurrent
reoffload (block bind/unbind always take rtnl). I guess
marking/unmarking filters as HW_FILTER in exactly the same places where
it is inserted/removed from hw_list would also work.
