I don't think we should even remotely consider surrendering the XDP hook to module code. We restrict it to eBPF for a reason, because that framework is restricted in what it can do, what it can access, and how it can do so. Tom if you're going to do a cleanup that makes it so that drivers need less code to support XDP, that is awesome but please do only that. Don't combine it with more controversial changes. Thank you.

For this reason, I simply don't believe that BPF is magically more robust code than what is in a kernel module. Or to put it another way, do you think DPDK is going to put any restrictions on what a user can do over raw queues in userspace? If we put on artificial limits on XDP like it can only ever be BPF then we are just closing the door to its full potential and given more fodder for the userpace stacks to claim superiority. > Tom if you're going to do a cleanup that makes it so that drivers > need less code to support XDP, that is awesome but please do only > that. > > Don't combine it with more controversial changes. > We need this for TXDP; I have no interest in rewriting the TCP stack in BPF :-) Tom > Thank you.

We can actually control what externally written XDP eBPF programs can do, for kernel modules we have no such control or influence. This hook runs right in the driver and bypasses the entire stack, it has to execute in a hardened thing that cannot crash and it will not as long as BPF verifier is correct. And you're going to make it even more complicated what XDP offload in hardware actually means. With eBPF it is very clearly defined what the necessary execution engine is. Tom I'm strongly against being allowed to run arbitrary module code from the XDP hook, sorry. It is as important as the distinction between full stack offload and partial offload in those nice charts in your talks. :-)

And the relevant principle that I would draw from that is the "offload" means offloading functionality from the kernel **to** the device. Restricting what we implement in the kernel on the basis of whether or not it can be offloaded to a device is completely backwards in this regard. Tom

I'll add a configuration option like XDP_ALLOW_OTHER_HOOKS. The default will be to disallow setting any hook other than a BPF. If it is set, then we'll accept other hooks to be run. This way mostly restrict the interface by default, but still allow experimentation with other hook types like I need with TXDP or maybe the netfilter guys might want to fastpath netfilter etc. When we we bring a working robust implementation to netdev that show clear benefits then we can add those to BPF as the "allowed" hooks at that time. So this strictly controls the interfaces, but still also allows room for innovation.

I said it's because eBPF is constrained, and there is a very well understood universe of operations it can perform and what memory it can access. Whereas modules can touch any piece of kernel memory, loop, crash, deadlock, you name it. None of which is possible with eBPF.

The only reason I accepted XDP is entirely because it is limited in scope to eBPF. All eBPF programs execute in finite time, cannot loop, cannot deadlock, cannot access arbitrary pieces of kernel memory and datastructures. It is a well defined, constrained, and incredibly tightly controlled execution environment for implementing policy, monitoring and control.

None of which is possible with eBPF. So we have thousands or LOC coming into drivers every day anyway with all those properties anyway, so this "restricted" environment solves at best 1% of the problem. I must admit though that "loops" in code is now considered to be evil at the same level as deadlocks and crashes is amusing :-) Tom

And it's also incredibly invasive in the core data path of drivers. TBH it is not clear to me that the narrow use cases for XDP justifies adding this complexity being added to every driver. In any case, I withdraw the patch set. Tom

What you must understand is that no matter what someone outside of upstream writes into an eBPF program, it's safe, and we can absolutely prove this with the verifier and the invariants of the execution environment. Real kernel modules have no such restricted scope. This is the fundamental issue. Even if I agreed with you, it's tremendously frustrating that we haven't even touched the surface of what eBPF XDP can do, and yet you're openning the floodgates to something we cannot even prove we need or is required yet. XDP via eBPF in it's current form needs more work and it needs to be fully fleshed out and more user friendly. That's where the effort and engineering resources belong right now. After that you can say "Ok, now we have that just about feature complete, here is the thing that's not possible and that's why we need X" You think you can answer that right now, and I know that it's not true. There is so much that eBPF XDP can do with the right mix of care and helper functions. I actually really see no fundamental limit to what it is capable of doing with the proper design.

But just like eBPF that does not at all mean the logic of the program is correct. Getting into a mode where we drop every packet, or checksums are miscomputed, or a protocol field is miswritten is entirely possible. The value of coding in the Linux kernel, maybe the only truly relevant point compared to userspace stacks, is the scrutiny, the testing, the debugging, and the eyes of experts we get to look at every line going into the kernel to avoid such problems. Even though there's the possibility of crash or deadloacking the system, I would absolutely put the quality of kernel code over _any_ piece of userspace code _any_ day of the week. Maybe some day we'll see a process for XDP/BPF for reviewing and accepting code and you along with several of established experts on netdev will be earnestly reviewing such code, but until then I am more inclined to stick with writing kernel code for anything other than simple things that are amenable to BPF. The problem with kernel bypass is not just that it bypasses the well-written and well-tested kernel code, but that it also bypasses the process. Tom

XDP is valuable for fast userspace forwarding (e.g macvtap passthrough mode). I hope we can leave a window for this. Or we may need introduce other similar hooks.

Sounds like we can therefore meet that requirement and keep them in the kernel networking path, which supports all of our values and goals precisely.

There is no bulking and no reuse of instruction cache. There is no revolution in this approach. We will end-up with the same known performance problems when more hook users get added. Calling N-number of hooks per every packet, will just end-up flushing the instruction cache (like the issues we have today). Instead take N-packets, and then call the hooks by turn (store action verdicts in packet-vector). Such an architecture would be inline with that VPP, Snabb and DPDK is doing. Optimizing icache usage, and opens up for smarter prefetching of lookup tables. Imagine, having hook-1 identify lookup bucket and start prefetch, hook-2 access the bucket and prefetch table data, and hook-3 read data. This is what DPDK is doing see[1], and VPP is doing similar tricks to get it to scale to large route lookup tables. [1] http://dpdk.org/doc/guides/prog_guide/packet_framework.html#figure-figure35

Unfortunately though, we need the return codes to be processed in the driver so that API and driver model would have to change more. If we do this I suggest it's done sooner than later, as more drivers adopt XDP changing all the drivers for that API become much harder (as I saw with just the second version of this patch).

I'd say may we might be able to have a minimally invasive interface with something like: XDP_RUN(hook, xdp, drv_xdp_handle_action) This replaces xdp_run and return codes are processed in the called functions. Its a macro so that xdp_handle_action can be inlined. Batching could then be done in the backend XDP so that it would be transparent to the driver. We'd also probably want another call like so the driver can flush the queued packets when exiting the rx loop. Something like: XDP_FLUSH(xdp, drv_xdp_handle_action) The hook then contains a function callback that gives an array of pages to a function and returns an array of actions. Tom

Its a macro so that xdp_handle_action can be inlined. I don't see why callbacks are needed, since XDP programs (I assume) aren't supposed to block. This XDP_RUN ends up looking a lot like NF_HOOK, for no good reason that I can see (unlike NF hooks, we never do things like NF_QUEUE). > Batching could then be done in the backend XDP so that it would be > transparent to the driver. I also don't see how you can transparently batch and still allow the handler to be inlined - you'd have to stash a function pointer that you could call later when you decide to dispatch a batch of packets. To me, the sensible interface (which makes the batching explicit to the driver, which I think is necessary) is to have an int (or maybe unsigned int, which is the return type of xdp_hookfn, I'm not sure which is intended) member in struct xdp_buff. Then the driver can call something like XDP_RUN_ARRAY(napi, xdp_array, array_len); which is semantically equivalent to unsigned int i; for (i = 0; i < array_len; i++) xdp_array[i].ret = xdp_hook_run(napi, xdp_array + i); except that it may run the hooks in 'row-major order'. No callbacks needed, the driver can just loop over xdp_array reading the .ret and applying the relevant action to each packet. This also has the advantage that the driver knows how many packets it might have to process in a single batch (i.e. NAPI_POLL_WEIGHT) and can allocate the array statically, whereas an XDP hook that tried to transparently be 'helpful' would have to guess and/or use kmalloc. -Ed

Probably the biggest issues with XDP is the potential impact in the core data path on every driver for something that is a narrow use case feature. Minimizing the impact on drivers is a high order goal I believe, even if it might be at the expense of having complete flexibility. Tom > -Ed

I imagined the xdp_array[i].ret would be the XDP action return code. > except that it may run the hooks in 'row-major order'. > No callbacks needed, the driver can just loop over xdp_array reading > the .ret and applying the relevant action to each packet. > > This also has the advantage that the driver knows how many packets it > might have to process in a single batch (i.e. NAPI_POLL_WEIGHT) and > can allocate the array statically, whereas an XDP hook that tried to > transparently be 'helpful' would have to guess and/or use kmalloc. I also think the driver need to be explicit about batching. This related to the RX stages I'm talking about. Saeed is working on implementing that for mlx5, I got some PoC patches today and I'll soon test that.

This patch creates an infrastructure for registering and running code at XDP hooks in drivers. This extends and generalizes the original XDP/BPF interface. Specifically, it defines a generic xdp_hook structure and a set of hooks that can be assigned to devices or napi instances. These hooks are also generic to allow for XDP/BPF programs as well as non-BPF code (e.g. kernel code can be written in a module). An XDP hook is defined by the xdp_hook structure. 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 structure and copies the values from the xdp_hook passed in. The register function also saves the pointer value of the xdp_hook 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, functions to register and unregister hooks on a device or individual instances of napi, and xdp_hook_run that is called by drivers to run the hooks.
