2.5 upgrade is missing USB Ethernet (ue0)

dotdash

I just keep a recent backup and a copy of the previous installer.
For a corporate environment, one should have a spare firewall available.

@dotdash
I have a spare portable firewall with 2.4.5 installed a couple of hundred miles away but I am stuck in this pointless Covid19 lockdown in England and I can't get home.

My corporate firewalls are setup with CARP, with a third machine in each rack as a cold standby/upgrade guinea pig.

@vmb That Ethernet adapter uses the Realtek chipset and you can see this link for the solution. https://forum.netgate.com/topic/161076/upgrade-to-2-5-0-went-well-after-an-additional-upgrade-of-the-realtek-ethernet-nic-driver

Thanks for the URL, I have linked to it here.

I will check it later today. It will certainly save a lot of time if it does work. I will try making the changes in /boot/loader.conf.local first as changes here at least stand a chance of surviving future upgrades.

re(4) is for Realtek PCI NICs. You probably want ure(4) which has never been included but is now built for 2.6 snaps. See:
https://forum.netgate.com/topic/161352/issue-with-upgrade-and-install-latest-version

For some reason it seems those devices are loaded as generic cdce in 2.4 and 2.6 but not 2.5. Unclear why yet.

The device will likely work much better with the correct ure driver.

If you need the 2.4.5p1 installer image just open a ticket and we can get it to you: https://go.netgate.com/

Sadly the Realtek kernel module didn't work for me. I get a kernel panic, fatal trap 12: page fault while in kernel mode. The intel Atom based device I am using has a Realtek NIC on the motherboard.

Fortunately, the FreeBSD 11.3 kernel was still present and I could boot it to delete my /boot/loader.conf.local .

I have come up with a temporary workaround using a VLAN capable Ethernet switch that I have here. I can configure VLANs for WAN and LAN to use the same parent interface. Alternatively, I could use the unused Atheros WLAN as a separate interface for WAN. I have only ever used it to provide a temporary access point, never used it as a client before in pfSense.

The ure or re module? Did you try loading either in real time?

As I said the re module will not help you with a USB device, it's a PCI driver.

@stephenw10
Yes, I tried a kldload of if_re.ko . kldstat reported it was loaded but because my machine's onboard Ethernet adapter is a Realtek the in-kernel version had already grabbed the interface.

I am looking for a way to upgrade to 2.6.0 from the 2.5.0 console but I can't find a way of doing this using a URL for a 2.6.0 installer image.

stephenw10

Yes, you would need to add that line to the loader file to load the alternative re driver in preference to the in kernel driver.

You can't upgrade to an installer image. You could try toedit the pkg repo line in the config file, reboot to apply it, then upgrade using menu option 13.
Add or edit the line:

<pkg_repo_conf_path>/usr/local/share/pfSense/pkg/repos/pfSense-repo-devel.conf</pkg_repo_conf_path>

Re-installing to 2.6 directly would be better though.

@stephenw10
Thanks. I will try the repo line edit first. If it fails, I will install 2.6.0 from a flash drive.

vmb

Upgrading to 2.6.0 using the repo edit worked well. I have a running firewall again with USB Ethernet.

stephenw10

Nice. Still at the reduced speed though?

You should try adding ure in the loader file so it's present at boot if you have not already.

dmesg shows ue0 binding to ure0 at full speed.

ue0: <USB Ethernet> on ure0

A grep for ure on /boot/loader.conf turns up nothing. I am happy the adapter is working again as it did on 2.4.5 .

stephenw10

Ah, that looks good.

Does it report the correct link speed now? Typically it does not using the generic driver.

@stephenw10
ifconfig shows...

media: Ethernet autoselect (1000baseT <full-duplex>)

Web GUI says the same for the interface status.

I have upgraded my remaining 2.4.5p1 to 2.5.2 today and it correctly recognises the USB Ethernet adaptor using kernel module if_ure.ko .

vmb

@vmb I have upgraded my 2.5.2 installs to 2.6.0 today. The automatic notifications I have configured made it clear that 2.6.0 works better for me.
