Netmap not supported for Intel X553 driver in pfSense 2.5.0
-
Hello,
I have the following board: https://www.supermicro.com/en/products/motherboard/A2SDi-4C-HLN4F
I use Netmap(Suricata) on pfSense 2.5.0:
https://www.freebsd.org/cgi/man.cgi?query=netmap&sektion=4
The driver for FreeBSD as far as I know is this:
https://downloadcenter.intel.com/do...10-Gigabit-Network-Connections-Under-FreeBSD-
or from source net/intel-ix-kmod
pciconf -lvc output:

I understood that NETMAP is disabled on FreeBSD 12.1, as someone kindly provided this line:
MAX_NETMAP_OSVERSION= 1199999 # Doesn't build w/NETMAP on 12Also I requested help from Intel also here:
https://forums.intel.com/s/question/0D50P00004g25BHSAY/intel-x553-driver-support-for-freebsd-121Basically they've told me to not use FreeBSD 12.1 :)
I contacted also SuperMicro:
What I like to point out is, on pfSense 2.4.5 or 2.4.4 Netmap was running on Native mode, so it's not a hardware issue.
Also please note that ixgbe driver changes names depending on devices names as quoted in my discussion with FreeBSD guys:
Log Message: Update to the Intel ixgbe driver: - The driver loadables will now match the device names, something that has been requested for some time. - Rather than a modules/ixgbe there is now modules/ix and modules/ixvI didnt want to post a question before I tried to gather all the information I could. But it seems my last chance is with you.
Please go through my discussions with Intel and FreeBSD if you have time, and if you can, help me in order to solve this.
Thank you

why are you using pfsense 2.5.0 and not 2.4.5 then? it's not ready for production and it migrated to freebsd 12.1 only a couple of weeks ago
also I don't think anyone here can help you with this, it's something that intel/freebsd should do upstream -

also I don't think anyone here can help you with this, it's something that intel/freebsd should do upstreamI wanted to test 2.5.0, it's pretty solid besides the Netmap issue. Maybe pfSense 2.5.0 is not ready for production but what about FreeBSD 12.1, it isn't ready also? A great part of pfSense is still FreeBSD, and it seems nobody knows about this. If nobody will test, how we will find this issues?
Don't get me wrong, I'm not trying to point fingers, just to find a solution if possible, and if not just to report stuff, and if there is no solution, sure I will revert back to a previous version, but why shouldn't we benefit somehow from this in advance?

I got the following response from Intel:
The issue now is if I go with the driver included I got very low speeds ~150 Mbs/s, and I can't tune the interface because some parameters are missing:

@kiokoman
I tried already, but I tried with your module also:[2.5.0-DEVELOPMENT][root@Entaro.Blueshift]/root: kldstat Id Refs Address Size Name 1 17 0xffffffff80200000 38cefc0 kernel 2 1 0xffffffff83acf000 eed8 aesni.ko 3 1 0xffffffff83adf000 58f30 if_ix_updated.ko 4 1 0xffffffff84011000 ff0 cpuctl.ko 5 1 0xffffffff84012000 37e8 cryptodev.ko 6 1 0xffffffff84016000 b28 coretemp.koThe idea is if I load if_ix_kmod in /boot/modules/ or if I compile from Intel site and copy if_ix.ko to /boot/kernel, Netmap will not run in Native mode, so I achieve nothing. This process works well with FreeBSD 11.2, 11.3, but not above. The driver cannot be compiled with Netmap support, at least that I have understood from Eric's mail.
From Suricata log:
31/5/2020 -- 16:28:38 - <Error> -- [ERRCODE: SC_ERR_NETMAP_CREATE(263)] - Couldn't query netmap for ix3, error Operation not supported 31/5/2020 -- 16:28:38 - <Info> -- Going to use 1 thread(s) 31/5/2020 -- 16:28:38 - <Error> -- [ERRCODE: SC_ERR_NETMAP_CREATE(263)] - opening devname netmap:ix3/R failed: Operation not supportedI started netmap with dev.netmap.admode:1 in loader.conf.local which forces Netmap to start in Native mode, or otherwise fail.

did you try snort ?
-
@kiokoman I've installed it just now, the speed is actually worse ~ 98 Mbs/s. I don't see any startup entries or logs like Suricata have. There is one alert.log which is a txt format, and two logs in pcap format that I have read with tcpdump, but I cannot find nothing related to Netmap.
Maybe if you are more familiar with Snort:[2.5.0-DEVELOPMENT][root@Entaro.Blueshift]/var/log/snort/snort_ix322137: ls -al total 488 drwxr-xr-x 3 root wheel 512 May 31 18:15 . drwxr-xr-x 3 root wheel 512 May 31 18:13 .. -rw-r--r-- 1 root wheel 101523 May 31 18:21 alert -rw-r--r-- 1 root wheel 0 May 31 18:13 app-stats.log drwxr-xr-x 2 root wheel 512 May 31 18:13 barnyard2 -rw------- 1 root wheel 100 May 31 18:15 snort.log.1590938061 -rw------- 1 root wheel 377805 May 31 18:21 snort.log.1590938143 -
Netmap has turned out to be a big disappointment to me. I had very high hopes in the beginning when I first included netmap support in Suricata, and later in Snort on pfSense-2.5, that Inline IPS Mode with netmap would be a fantastic feature in both packages. However, the reality has been that the various NIC drivers seem to haphazardly support netmap operation, and the internal coding and exposed API of the netmap kernel device itself has changed several times over the last couple of years or so. Based on that, no wonder the NIC drivers have a hard time keeping up. So netmap operation is failing to live up to its promise.
Snort probably has the slower performance under emulation mode than Suricata due to the fact the Snort implementation is a bit older and uses the API version that only exposed a single host ring. The latest netmap API exposes multiple host rings if the NIC driver supports them.
-
The ideea is as I'm testing it right now, it will be impossible to run Suricata or Snort anymore, with this ifllib framework. On Linux works ok, I can reach from 620 to 960 Mbps so it's not a hardware issue.
Also it worked at full speed on FreeBSD 11.2, I think maybe it's not only Netmap but this iflib framework that Intel talks about.
I used Snort only to respond to @kiokoman for testing, but I'm not able to tell from logs in which mode NETMAP started like in Suricata. Do you know how?
Also there is somehow the possibility that NETMAP will start to emulated mode regardless of dev.netmap.admode:1 setting with iflib framework? I'm thinking maybe this iflib framework hides or doesn't report correctly the starting mode?
On FreeBSD 11.2 for example I achieved full speed only after I compiled my own driver, so I had:
- NETMAP native mode : 600 - 960 Mbs/s - with Intel compiled driver
- NETMAP emulated mode: 150 Mb/s - with included FreeBSD driver in pfSense installation
On FreeBSD 12.1 I have:
- Netmap native mode(at least that's what the system reports) : 150 Mbs/s - with included FreeBSD driver in pfSense installation
- Netmap emulated mode: 150 Mbs/s - with Intel driver compiled from Intel site, or from FreeBSD source: intel-ix-kmod
I don't know what to ask anymore. Only one question, what will we do with Suricata or Snort when pfSense 2.5.0 will be production ready?
-
Be careful with the term "pfSense driver" as that is not really accurate. There are no "pfSense drivers" at all. They simply use what is included by default from upstream FreeBSD according to the FreeBSD version they are using.
Now on to the topic at hand --
I am not a netmap device expert by any means. I have also read a limited amount about the iflib framework. Still have not fully digested what little bit I did read about it, but I understand it to be yet another new gizmo for abstracting stuff. That seems to be the favorite pastime of developers these days -- abstracting things in layer upon layer of additional software to supposedly make it all easier to use. Well, I'm not 100% convinced, but then nobody asked me anyway ...
.When it comes to trendy hardware support (and that would include things like netmap, NIC drivers and so forth), Linux is better than FreeBSD. So living with less than optimum hardware support is just one of the things we must accept when using a FreeBSD platform.
As for what happens with Snort and Suricata in pfSense-2.5, well, Legacy Mode still works and should continue working. Of course it is not ideal when it comes to IPS. On the other hand, the utility of an IDS/IPS is steadily diminishing as more and more traffic becomes end-to-end encrypted. The rules have less and less traffic to actually inspect in any meaningful way.
-
By pfSense driver I've meant the default driver, and to point out I did nothing to change it. You are correct it comes from FreeBSD not from pfSense. I will change the term.
For the rest, what is to be said. I like your diplomacy

I understood that NETMAP is disabled on FreeBSD 12.1, as someone kindly provided this line:
That is not true ... in FreeBSD 12.0/12.1, Netmap had been moved to IFLib.
@NRgia said in Netmap not supported for Intel X553 driver in pfSense 2.5.0:
How can I enable or fine tune the interface with the new iflib driver?
You cannot. The problem is currently FreeBSD 12.0 and 12.1 is still using the old Intel Pro1000 driver instead of Intel 25 driver released in January 2020. The solution is either wait for FreeBSD to incorporate the new driver into FreeBSD 12.1 or encourages pfSense to incorporate it in pfSense 2.5 final release.
I really wished it was easy for us to install driver updates than having to wait for it to be compiled by FreeBSD ... that's why I am encouraging pfSense to do it since the NIC is the essence of a firewall.
-
- Why we must wait for upstream, the driver and the framework it's not open source? Or maybe not the Intel driver.
- It requires recompilation of the kernel?
- There is no new compatible driver with iflib from Intel?
I noticed that you talked with Luigi. I sent an email to him and he introduced me to two of his friends: Vincenzo Maffione and Giuseppe Lettieri. Should I go further with asking them for a solution, or your investigation with Luigi points to the conclusion that the Netmap implementation is fine?
What about the parameters that we used to tune for getting the right buffers, queues, etc. My understanding is that all of those have different names now, and we have to tune them through iflib, before Intel driver is even loaded. All the tutorials are now obsolete?
I don't think it's ok for us to play a waiting game here, we may see the final version omitting this issue, due to lack of upstream implementation
I also started a topic on FreeBSD forums here https://forums.freebsd.org/threads/intel-x553-driver-support-for-freebsd-12-1.75588/ maybe you can drop a line there also, someone may see it.
I will also sent this issue to FreeBSD e-mail group freebsd-net@freebsd.org if you didn't do this already
Thank you

Yes, I wish I knew how to do it ... it can take up to 18Hrs to compile. The compatible driver is the Pro1000 which I am using now.

That why I believe it is pfSense responsibility to make sure releases have the latest drivers for NIC and stop leaving it up to FreeBSD ... without the NIC, the firewall is useless. Unfortunately, addressing the issue on FreeBSD forum is a moot point because they think or believe it's pfSense responsibility. They don't encourage discussion on pfSense. Pretty soon pfSense 2.5RC will be out; so, we need folks making noise.

https://downloadcenter.intel.com/download/22283/Intel-Ethernet-Adapter-Complete-Driver-PackBut if go for PRO 1000 specifically you will find that the latest version for FreeBSD is 2.5.14 or 7.7.8 depending the card
For my chipset X553 it uses PROXGB driver:
and the last version is from last year:
https://downloadcenter.intel.com/download/14688/Intel-Network-Adapters-Driver-for-PCIe-10-Gigabit-Network-Connections-Under-FreeBSD-?wapkw=intel%20x550%20networkSo I think it should have been included by now, but I can't tell because the system reports 4.0.1-k.
What is your status now, are you using NETMAP in emulated mode, not at all and you are waiting for this to get fixed?
Thank you

But if you are using Netmap in NATIVE mode, what is your issue then ? Or it got fixed after you updated to FreeBSD 12.1 by default? What speeds do you achieve?
My issue is that I have a very high speed penalty.
With FreeBSD 12.1 default driver I get 150 Mbs/s, and NETMAP starts in NATIVE mode
If I compile my own driver I will get the same speed, but NETMAP will not start in NATIVE mode, only in emulated mode
In comparison with FreeBSD 11.2 where I got between 800-960 Mbs/s it's a huge difference.Thank you

The current driver when in iflib does not allow traffic graph to show. That's great info to have on the WebGUI at a glance. The new driver should make that happened.

I'm using 25.1 even, but I think you are referring to the driver package rele
On FreeBSD 11.2 it worked this way, compile the driver and override the ko in /boot/kernel/ or copy as a module in /boot/modules. Sure, adding the proper line in loader.conf.local is also needed
On FreeBSD 11.3,12.1 if I compile my own driver I will achieve nothing, because my own compilation, will not include NETMAP native support due to iflib framework, hence it will run in Emulated mode at 150 Mbs/s, and if I go with the FreeBSD 12.1 driver, NETMAP will start in Native mode, but I will achieve the same speed 150 Mbs/s, so something is not right with the driver.I contacted you because in your thread here: https://forum.netgate.com/topic/144979/porting-bge-driver-to-iflib/5
you mentioned you had problems with NETMAP Native support and you attempted to compile some drivers.
In this context we have the same issue I think. Can you elaborate, what was your status with BGE in the end?
Thank you
