[Solved] 18.1.5 issues

[elektroinside]

I don't know what's happening after the upgrade on my box.

So, here it goes:

1. Whenever I restart the box, I have no internet connectivity on the LAN clients; pinging from the OPNsense GUI works fine, pinging from the LAN clients (using IP or FQDN) fails
2. To make things work again on the LAN side, I have to either:
- disconnect/connect my PPPoE link (on the WAN)
- or edit the default gateway without any modification, save and apply
3. Right after the reboot, a lot of things are still loading of course, but the GUI is available at one point. When some of the services loaded (as pictured in the attached Screenshot_36.png), internet works on the LAN side. When everything is fully loaded (as pictured in Screenshot_37.png) internet on the LAN side no longer works
4. Sometimes I can't even ssh to the box from the LAN if I don't reconnect the WAN to fix the internet connectivity (something is not binding to some interfaces, I guess)

Errors in the log:
Line 63: Mar 22 19:40:49 gateway kernel: module_register_init: MOD_LOAD (vesa, 0xffffffff810ab110, 0) error 19
Line 97: Mar 22 19:40:49 gateway kernel: pcib0: _OSC returned error 0x10
and a bunch of "Line 268: Mar 22 19:40:54 gateway sshd[48206]: error: Bind to port 22 on ... failed: Can't assign requested address."

I already tried a clean install, which in my case is a pain in the *ss:
1. Install 17.7.5 first, because I get the segmentation fault error with 18.1
2. Upgrade to the latest version
3. Install plugins
4. Restore backup

Do you run some VPN in the Box? Disable gateway monitoring

[elektroinside]

I do have OpenVPN.
I didn't have gateway monitoring at the beginning. I enabled it later, to see what changes...
But having that disabled didn't work.
I'll try again...

Update: confirming that disabling gateway monitoring doesn't help... same thing

If you relied on the NAT patch, did you reapply it after the update? This fix will not be included until 18.1.6.

# opnsense-patch 7a823c56a

[elektroinside]

No, it's not my case. I think something changed in the network stack (just a hunch).
But thanks anyway.

[elektroinside]

Actually, a lot changed on the stack, judging by the changelog... will take the opportunity to underline (once more) the importance of a stable/better tested (by the community as well) release channel.

Hi there,

18.1.5 has been unusually quiet and apart from PTI/IBRS lacks behavioural changes almost entirely.

Just try with 18.1.4 package to see if that caused it:

# opnsense-revert -r 18.1.4 opnsense

The only change that looks related is "interfaces: ignore dynamic linkup events for unassigned interfaces".

If it's the same issue, I don't particularly believe it's the kernel but why not switch back this one as well...

# opnsense-update -kr 18.1
# /usr/local/etc/rc.reboot

It could be a local issue surfacing more clearly and / or entirely unrelated to the software. Reinstall does not yield different results most of the time.


Cheers,
Franco

Yep, 18.1.4 works fine after a reboot. Rebooted 3 times, no issues.
The downgrade was performed in a matter of seconds. At first, i believed it failed because of the speed, but the GUI is showing that I'm on 18.1.4. So i think it worked. Anyway, rebooting no longer breaks internet connectivity on the LAN side, so there's something probably incompatible with my @$&43#_-;!!?: PPPoE link and OPNsense 18.1.5.

I really like the new kernel. Despite the slightly higher CPU usage, it is very snappy and everything is just very fast.

[franco]

Sorry for the late repy.

Flip this... either from 18.1.4 or 18.1.5. 18.1.4 would get worse, 18.1.5 would get better when done.

# opnsense-patch d94ed6d8

(It's a theory.)


Cheers,

Updated to 18.1.5 and applied the patch.
And it works!

Thank you Franco, well done!

Btw, it's "opnsense-patch", right?

[fabian]

yes

[franco]

Alright, this is a fix so something else is going on... what is your WAN and LAN config with regard to IPv4 and IPv6 setup types?


Cheers,
Franco

[elektroinside]

WAN: IPv4 is PPPoE, IPv6 is DHCPv6
LAN1: IPv4 is "Static IP", IPv6 is "Track interface"
LAN2: IPv4 is "Static IP", IPv6 is disabled (this is for the guest wifi network, without a captive portal)

On both LANs, DHCPv4 is running, no DHCPv6.
Simple, by the book setup

[franco]

When you say:

"1. Whenever I restart the box, I have no internet connectivity on the LAN clients; pinging from the OPNsense GUI works fine, pinging from the LAN clients (using IP or FQDN) fails"

Do you mean LAN1, LAN2 or both?


Cheers,
Franco

[franco]

And more interestingly: Is IPv4 or IPv6 not working, or both?
