Official Realtek Driver Binary 1.95 For 2.4.4 Release

[Nazar]

Thank you for answers.

Where could i load the source for driver? and should that be some special source code (not original from pfsense - that one not working properly)? Is there any tutorial how to compile that driver? And who actualy wrote that source code?

I am using custom Realtek driver for Lan not for WAN. Is it still danger?

Yes i am using zfs system. I wonder is that correct spot /bootpool/ to put that driver.

@Nazar If it loads, it ok.. From where isn't important.
If its rogue and it runs, anything goes.

Well the question is about security. If custom driver has some backdoor and it is set as LAN interface .. is it still danger? (is it more dangere to set it as WAN)? Can LAN custom driver breck Firewall rules and give backdoor to Network? I am very new in pfsense .. my questions may be silly
Thank you for answers

[netblues]

@Nazar Well, this isn't really a pfsense question. pfsense is based on freebsd and pf. So any drivers are talking to the os kernel, and this is definetely os specific.
I doubt if it makes any difference if its on lan or wan.
Its very difficult for such a backdoor to go undetected in any case.
In doubt, you should compile it yourself (and then you also need to trust the compilation environment too.)
Since realtek ethernet chipsets seem to have issues with freebsd, any important installation is using intel cards anyways.

[kiokoman]

@Nazar , it's not easy / not worth, use the one you have downloaded, i'm pretty sure it's safe..
you need a freebsd installation with source (virtual machine or something)
instructions are here anyway

just changing the commands from 1.94 to those of 1.95.

[Nazar]

Ok Thanks.

And here extra question about custom driver for Realtek.

If i use custom driver does it mean that everytime when pfsense update i have to search/compile new custom driver for new version?

Thanks

[netblues]

@Nazar That really depends if the update also changes underlying os version.
Sometimes it does sometimes it does not.
it is something to be aware of, however pf versions don't come that often.
And opting for an Intel based lan chipset solves all this.

If it fails to load because of a kernel mismatch it will just use the in-kernel driver instead. It's not as bad as an otherwise unsupported device.

Interestingly I was using the 2.4.5 compiled driver and it fixed all my issues. I then upgraded pfsense to 2.4.5_P1. Kldstat showed that driver was still loading fine after the upgrade.
But the interface stopped responding after approx 48 hours.

I've now updated to the 2.4.5_p1 compiled driver from above, I will test this out for stability and report back.

Edit: Anyone else using this version and using vlans with hairpinning on a single interface? I'm getting atrocious performance now however it used to work perfectly.

Today i have to setup old server for pfSense (X7SLM-L MB with 2xRealtek RTL8111C-GR). After some time of intensive load by LAN networks - connection is hangs for few minutes and then themselves restore work. I build Realtek drivers 1.95, and install, seems that they works stable, but that drivers didn't use MSI-X interrupts and CPU usage is 10-20% more (40-60%), than on stock FreeBSD drivers (25-30%).
Then i try to disable "CPU Spread Spectrum" in BIOS and use stock FreeBSD drivers, and with a big surprise Realtek starts works stable!
So, you can try do this, maybe there is a point of problem with Relatek LAN.

A little update (for those who wants to try it out):

New Realtek driver 1.96.04 for BSD systems

I compiled it against FreeBSD 11.3-release (latest) and worked for me.

Unfortunatey i am not able to upload it here, so you are about to compile for yourself at the moment.

[netblues]

@wkn said in Official Realtek Driver Binary 1.95 For 2.4.4 Release:

1.96.04

Any chance for a link/paste to the change log? (googling didn't reveal anything)

[Cybermaze]

I want to thank the original poster TheNarc, this thread and the compiled drivers provided were very helpful. The compiled driver is much better than the default drivers, it really made me realize how terrible the default drivers are.

In the end I chose to switch to another PC/server with Intel NICs, even if this is just for a home network.

Thanks again!

@netblues

Realtek is not very "open" in their information policies. So don't expect anything. Also the update frequency is very slow for network drivers.

[knight-of-ni]

Just downloaded, built, and installed the 196.04 if_re.ko driver on one of my pfsense boxes. It's too soon to declare success, but so far so good.

For those that don't already know a good set of instructions can be found here:
https://gist.github.com/jovimon/524e116471f249626fd2ccd141f3fe05

[netblues]

Anyone care to also upload the compiled driver please?

[knight-of-ni]

Here is the 196.04 driver I built:

Thanks to everyone who has kept this thread alive, and for pointing out 1.96. I try to check the Realtek driver page periodically but hadn't since this version was released. @knight-of-ni thanks for posting a compiled driver. I plan to load it on my two machines as well, but just wanted to confirm that you build it for 2.4.5-RELEASE-p1 (FreeBSD 11.3-STABLE) and not a 2.5 pre-release before I do. Thanks again!

[knight-of-ni]

I built if_re.ko in a vm running FreeBSD 11.3-RELEASE. Works for me.
