* [PATCH RFC 0/3] xdp: Generalize XDP

This patch set generalizes XDP by make the hooks in drivers to be
generic in the same manner of nfhooks. This has a number of
advantages:
- Allows alternative users of the XDP hooks other than the original
BPF
- Allows a means to pipeline XDP programs together
- Reduces the amount of code and complexity needed in drivers to
manage XDP
- Provides a more structured environment that is extensible to new
features while being mostly transparent to the drivers
The generic XDP infrastructure is based on how nfhooks works. The new
xdp_hook_ops structure contains callback functions and private data
structure that can be populated by the user of XDP. The hook ops are
registered either on a netdev or a napi (both maintain a list of XDP
hook ops). Allow per netdev ops makes management of XDP a lot simpler
when the intent is for the hook to apply to the whole driver (as is the
case with XDP_BPF so far). The downside is that we may need per napi
data (such as counters of returned actions).
The xdp_hook_ops contains three fields of interest. The "hook" field is
the function that is run for the hook. This takes a private data field
and the xdp_buff as arguments. "priv" is private data and "put_priv"
is a function called when XDP is done with the private data. In XDP_BPF
terminology the hook field is bpf_prog_run_xdp, "priv" is the xdp_prog,
and "put_priv" is bpf_prog_put.
The meaning of ndo_xdp is also changed. There are two commands for this
nod: XDP_DEV_INIT and XDP_DEV_FINISH. XDP_DEV_INIT is called the first
time an XDP hook is set on a device, this is primarily intended to
allow the device to initialize XDP (allocated the XDP TX queues for
instance). XDP_DEV_FINISH is called when the last XDP hook is
removed from a driver so that the driver can cleanup when XDP is done.
A new net feature is added NETIF_F_XDP so that a driver indicates
that is supports XDP.
The primary modification to a driver to support XDP is that it call
xdp_hook_run in the receive path (equivalent to bpf_prog_run in
previous XDP-BPF). The driver must deal with the four XDP return
actions XDP_PASS, XDP_DROP, XDP_TX, and XDP_ABORT.
xdp.h contains the interface to register and manage XDP hooks.
Tested:
Created a simple hook that does XDP_PASS and saw it works. A lot more
testing is needed for this.

* [PATCH RFC 1/3] xdp: Infrastructure to generalize XDP
From: Tom Herbert @ 2016-09-20 22:00 UTC (permalink / raw)
To: davem, netdev
Cc: kernel-team, tariqt, bblanco, alexei.starovoitov, eric.dumazet,
brouer
In-Reply-To: <1474408824-418864-1-git-send-email-tom@herbertland.com>
This patch creates an infrastructure for registering and running code at
XDP hooks in drivers. This is based on the orignal XDP?BPF and borrows
heavily from the techniques used by netfilter to make generic nfhooks.
An XDP hook is defined by the xdp_hook_ops. This structure contains the
ops of an XDP hook. A pointer to this structure is passed into the XDP
register function to set up a hook. The XDP register function mallocs
its own xdp_hook_ops structure and copies the values from the
xdp_hook_ops passed in. The register function also stores the pointer
value of the xdp_hook_ops argument; this pointer is used in subsequently
calls to XDP to identify the registered hook.
The interface is defined in net/xdp.h. This includes the definition of
xdp_hook_ops, functions to register and unregister hook ops on a device
or individual instances of napi, and xdp_hook_run that is called by
drivers to run the hooks.

Hi Jesper,
Can you take a look (or try) the RFC patches I just posted to
generalize XDP. I believe that should subsume most of what you're
doing here!
Thanks,

I beg to disagree.
There are way more drivers than subsystems and if you had to go around
unselecting all NIC drivers for CONFIG_ETHERNET to be turned off, and
with CONFIG_ETHERNET=n you'd finally be able to turn networking off,
then this would be a nightmare.
IMHO it is much nicer for the poor user configuring the kernel to have a
single configuration prompt for PTP support, and then have whatever
driver that can provide a PTP clock just do it (or omit it) based on
that single prompt. Prompting for PTP support for each individual
ethernet driver is silly.

Single BPF program that encodes whatever logic is required. This is
what BPF is for. If it absolutely has to run two programs in sequence
then it can still do that even though I really don't see much of a
point of doing that in a high performance environment.
I'm not even sure yet I understand full purpose of this yet ;-)

This allows other use cases than BPF inserting code into the data
path. This gives XDP potential more utility and more users so that we
can motivate more driver implementations. For instance, I thinks it's
totally reasonable if the nftables guys want to insert some of their
rules to perform early DDOS drop to get the same performance that we
see in XDP.

Agreed, if there's one thing I would change in cls_bpf, then it's getting
rid of the (uapi unfortunately) list of classifiers and just make it a
single one, because that's all that is needed, and chaining/pipelining
can be done via tail calls for example. This whole list + callback likely
also makes things slower. Why not let more drivers come first to support
the current xdp model we have, and then we can move common parts to the
driver-independent core code?

* [PATCH] ptp_clock: future-proofing drivers against PTP subsystem becoming optional

Drivers must be ready to accept NULL from ptp_clock_register() if the
PTP clock subsystem is configured out.
This patch documents that and ensures that all drivers cope well
with a NULL return.

Let's have the basics merged now and work out the actual Kconfig issue

* [PATCHv3 net-next 1/2] net: dsa: mv88e6xxx: Add helper for accessing port registers
From: Andrew Lunn @ 2016-09-20 23:40 UTC (permalink / raw)
To: David Miller; +Cc: Vivien Didelot, netdev, Andrew Lunn
In-Reply-To: <1474414832-1638-1-git-send-email-andrew@lunn.ch>
There is a device coming soon which places its port registers
somewhere different to all other Marvell switches supported so far.
Add helper functions for reading/writing port registers, making it
easier to handle this new device.
Signed-off-by: Andrew Lunn <andrew@lunn.ch>
---
v2:
Call mv88e6xxx_{read|write} in wrappers
Change some (err < 0) to plain (err)
v3:
reg = reg & foo -> reg &= foo
Fix over zealous s/ret/err

* [PATCHv3 net-next 0/2] Preparation for mv88e6390
From: Andrew Lunn @ 2016-09-20 23:40 UTC (permalink / raw)
To: David Miller; +Cc: Vivien Didelot, netdev, Andrew Lunn
These two patches are a couple of preparation steps for supporting the
the MV88E6390 family of chips. This is a new generation from Marvell,
and will need more feature flags than are currently available in an
unsigned long. Expand to an unsigned long long. The MV88E6390 also
places its port registers somewhere else, so add a wrapper around port
register access.
v2:
Rework wrappers to use mv88e6xxx_{read|write}
Simpliy some (err < ) to (err)
Add Reviewed by tag.
v3::
reg = reg & foo -> reg &= foo
Fix over zealous s/ret/err
Andrew Lunn (2):
net: dsa: mv88e6xxx: Add helper for accessing port registers
net: dsa: mv88e6xxx: Convert flag bits to unsigned long long

Good question. Since fq_codel does not (currently) implement pacing,
it would not be sufficient to get the required behavior.

Reasonable point with nftables but are any of these users on the table
already and ready to consume non-skbs? It would be a pity to add this
complexity and cost if it is never used.
I don't see how we can ensure performance if we have multiple
subsystems register for the hook each adding their own parsers which
need to be passed through sequentially. Maybe I'm missing something.

This fails to build with the following config. Looks like IPVLAN now has
dependency on netfilter.

fq_codel is stochastic, so it wont work very well on hosts with
1,000,000 flows or more...
fq_codel is aimed for routers, while sch_fq targets hosts,
implementing pacing at a minimal cost (one high resolution timer per
qdisc)

Well, need to measure to ascertain the cost. As for complexity, this
actually reduces complexity needed for XDP in the drivers which is a
good thing because that's where most of the support and development
pain will be.
I am looking at using this for ILA router. The problem I am hitting is
that not all packets that we need to translate go through the XDP
path. Some would go through the kernel path, some through XDP path but
that would mean I need parallel lookup tables to be maintained for the
two paths which won't scale. ILA translation is so trivial and not
really something that we need to be user programmable, the fast path
is really for accelerating an existing kernel capability. If I can
reuse the kernel code already written and the existing kernel data
structures to make a fast path in XDP there is a lot of value in that
for me.

We can optimize for allowing only one hook, or maybe limit to only
allowing one hook to be set. In any case this obviously requires a lot
of performance evaluation, I am hoping to feedback on the design
first. My question about using a linear list for this was real, do you
know a better method off hand to implement a call list?
Thanks,
Tom

it's an interesting idea to move prog pointer into napi struct,
but certainly not at such huge cost.
Right now it's 1 load + 1 cmp + 1 indirect jump per packet
to invoke the program, with above approach it becomes
6 loads + 3 cmp (just to get through run_needed_check() check)
+ 6 loads + 3 cmp + 2 indirect jumps.
(I may be little bit off +- few loads)
That is a non-starter.
When we were optimizing receive path of tc clast ingress hook
we saw 1Mpps saved for every load+cmp+indirect jump removed.
We're working on inlining of bpf_map_lookup to save one
indirect call per lookup, we cannot just waste them here.
We need to save cycles instead, especially when it doesn't
really solve your goals. It seems the goals are:
>- Allows alternative users of the XDP hooks other than the original
> BPF
this should be achieved by their own hooks while reusing
return codes XDP_TX, XDP_PASS to keep driver side the same.
I'm not against other packet processing engines, but not
at the cost of lower performance.

this can be done already via bpf_tail_call. No changes needed.

hmm:
534 insertions(+), 144 deletions(-)
looks like increase in complexity instead.
> - Provides a more structured environment that is extensible to new

don't see that in these patches either.
Things like packet size change (that we're working on) still
has to be implemented for every driver.
Existing XDP_TX, XDP_DROP have to be implemented per driver as well.
Also introduction of xdp.h breaks existing UAPI.
That's not acceptable either.
