You might want to read the following article in the FreeBSD Journal: = https://freebsdfoundation.org/our-work/journal/browser-based-edition/rack-= and-alternate-tcp-stacks-for-freebsd/ There is no specific area for testing.

I guess that is = regression by transition of route(8) to = NETLINK.

Can you please build sbin/route from = source without NETLINK and give it another try ?

```
# cd = /usr/src/sbin/route
# = setenv MK_NETLINK_SUPPORT no

```

Hi Benoit,

I = managed to repeat this bug.

As = a workaround, add an IPv4 address to the outgoing interface (vlan200 in = your case),
```
# ifconfig vlan200 inet = x.x.x.x/y
```

then retry = adding the route
```
# route add -net 10.200.1.1/32 = -inet6 fe80::9439:36ff:fef0:7cbd%vlan200
```


```

ping6 to `fe80::9439:36ff:fef0:7cbd%vlan200` works. = What I am doing wrong? Configuration of the interface is the = following:

```
vlan200: = flags=3D1008843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST,LOWER_UP> = metric 0 mtu 1500

On latest = freebsd 14.0 release , I am trying to join an ipv4 address over an IPV6 = local link using the following command :

`route add -net = 10.200.1.1/32 -inet6 fe80::9439:36ff:fef0:7cbd%vlan200`

But I  get the = following error:

```
route add -net 10.200.1.1/32 -inet6 = fe80::9439:36ff:fef0:7cbd%vlan200
add net 10.200.1.1: gateway fe80::9439:36ff:fef0:7cbd%vlan200 = fib 0: Invalid argument

I guess that is = regression by transition of route(8) to = NETLINK.

Can you please build = sbin/route from source without NETLINK and give it another try = ?

```
# cd /usr/src/sbin/route
# = setenv MK_NETLINK_SUPPORT no
# make
```

Hi = Benoit,

I managed to repeat this = bug.

As a workaround, add = an IPv4 address to the outgoing interface (vlan200 in your = case),
```
# ifconfig vlan200 = inet x.x.x.x/y
```

then retry adding the route
```
# route add -net 10.200.1.1/32 = -inet6 fe80::9439:36ff:fef0:7cbd%vlan200
```


Hi Alexander,

I = think the logic of adding route from NETLINK routine is not = complete.

After = bumping netlink debug level,
```
# sysctl = net.netlink.debug.nl_route_debug_level=3D9
```

I got these from kernel = message:
```
# dmesg | = tail
...
[nl_route] finalize_nhop: Unable to = determine ifa, skipping
[nl_route] rtnl_handle_newroute: Error = creating nexthop

/* Both nh_ifp and gateway are = set */

*perror =3D = EINVAL;
return = (NULL);
}

}
```
If the = outgoing interface `nh->nh_ifp` does not have any IPv4 = addresses, we should try ifaddrs on other = interfaces,
and have 0.0.0.0 as the last sort ( in case the = net stack is IPv6 only, i.e., no IPv4 addresses available = )



```

ping6 to = `fe80::9439:36ff:fef0:7cbd%vlan200` works. What I am doing = wrong? Configuration of the interface is the following:

```

Wasn't it merged ? (also pretty = sure I did test it in freebsd 13).

FWIW: it works fine on CURRENT

# ifconfig vlan8 destroy
# ifconfig vlan8 = create vlandev bge0 vlan 8 up
# ifconfig vlan8 inet6 = -ifdisabled auto_linklocal
# route add -net 10.11.13.0/24 = -inet6 fe80::360a:11ff:fe1b:404e%vlan8
add net 10.11.13.0: = gateway fe80::360a:11ff:fe1b:404e%vlan8 fib 0

It looks like the fix is in = f818559774cb0c1516364c4beca361480fd68b5b . Zhenlei, could you please MFC = this one[1] ?

Cherry-picking = it to stable/14 makes route fully functional. I have tested it between = stable/14 with this fix applied and CURRENT.

Thanks= for finding the fix and the confirmation , I'll take care of that = :)

My laptop has 802.11AC card for which there is no kernel driver available. I am I use a USB wifi adapter to access the wifi router. I am having sporadic DNS failures . After reboot, everything works fine but after some time (30 minutes to a couple of hours), Internet connections start to fail. When this happens, I am able to ping 1.1.1.1, my DNS server. However, # drill yahoo.com (or any other name) fails with following error: Error: error sending query: Could not send or receive, because of network error Other devices connected to same Wifi router continue to work fine. I ran drill under truss and it appears after sendto to 1.1.1.1, no response comes. After this error occurs, it stays like that for many some time (20-30 minutes) and sometimes it gets resolved by itself. #uname -a FreeBSD bsd12 13.0-RELEASE-p13 FreeBSD 13.0-RELEASE-p13 #0: Mon Aug 29 19:52:47 UTC 2022 root@amd64-builder.d aemonology.net:/usr/obj/usr/src/amd64.amd64/sys /GENERIC amd64 Can someone please help me debug this problem?

Wasn't it merged ? (also pretty = sure I did test it in freebsd 13).

FWIW: it works fine on CURRENT

Cherry-picking it to = stable/14 makes route fully functional. I have tested it between = stable/14 with this fix applied and CURRENT.

Thanks = for finding the fix and the confirmation , I'll take care of that = :)

Done. The fix = and tests are all MFCed into stable/14 branch.

I'm going to suggest that this might be a symptom of your usb port/hub hanging-up/ disconnecting due to inactivity. Your BIOS setup may have a setting associated with that. OTOH I don't know what NIC driver you're using for your USB network adapter. When you discover you can't perform DNS lookups, are you still associated? eg; does the output of ifconfig still show associated? What are the settings in rc.conf(5) related to your network setup? > > Thanks, > Sreenath HTH --Chris From nobody Fri Mar 15 04:13:10 2024 X-Original-To: freebsd-net@mlmmj.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mlmmj.nyi.freebsd.org (Postfix) with ESMTP id 4TwrT827Cgz5FDw6 for ;

Hi Chris,

Thanks for your message.
The w= ifi continues to be associated with access point, and I can ping 1.1.1.1 as= well.
My USB wifi interface is rtwn(earlier urtwn)

It is just th= at DNS queries fail, even when 1.1.1.1 is accessible, at least to ping.
=
Is it possible that UDP communication is failing?
Is there any log = information that can shed more light on the issue?

thanks,

I'm going to suggest that this might be a symptom of= your usb port/hub
hanging-up/
disconn= ecting due to inactivity. Your BIOS setup may have a setting
associated
with that. OTOH I don't know what NIC dri= ver you're using for your USB
network
= adapter. When you discover you can't perform DNS lookups, are you still associated?
eg; does the output of ifconf= ig still show associated? What are the settings

If ping(8) is your only failure. I'd not be surprised that those addresses you're pinging drop ICMP packets. As they're frequently used in attacks. The FreeBSD ping(8) used to also have an alternate (UDP?) option. My advice; try (pinging/tracerouting) additional hosts before concluding it's your DNS/network. Perl.com, fe; doesn't drop ICMP echo, neither does microsoft.com. If you get a response. It's probably just the hosts you've been using. Not your DNS/Net. --Chris > > thanks, > Sreenath > > On Friday, March 15, 2024 at 12:48:47 AM GMT+5:30, Chris > wrote: > > On 2024-03-14 00:12, Sreenath Battalahalli wrote: >> Hi, >> >> I have been using freebsd as my primary OS on my ACER laptop for many years >> now. >> My laptop has 802.11AC card for which there is no kernel driver available I >> am I >> use a USB wifi adapter to access the wifi router. >> >> I am having sporadic DNS failures . >> >> After reboot, everything works fine but after some time (30 minutes to a >> couple of >> hours), Internet >> connections start to fail. >> >> When this happens, I am able to ping 1.1.1.1, my DNS server. >> >> However, >> # drill yahoo.com (or any other name) fails with following error: >> >> Error: error sending query: Could not send or receive, because of network >> error >> >> Other devices connected to same Wifi router continue to work fine. >> >> I ran drill under truss and it appears after sendto to 1.1.1.1, no response >> comes. >> >> After this error occurs, it stays like that for many some time (20-30 >> minutes) and >> sometimes it gets resolved by itself. >> >> >> #uname -a >> FreeBSD bsd12 13.0-RELEASE-p13 FreeBSD 13.0-RELEASE-p13 #0: Mon Aug 29 >> 19:52:47 >> UTC 2022    root@amd64-builder.d >> aemonology.net:/usr/obj/usr/src/amd64.amd64/sys >> /GENERIC  amd64 >> >> Can someone please help me debug this problem? > I'm going to suggest that this might be a symptom of your usb port/hub > hanging-up/ > disconnecting due to inactivity.

So that is fine. Just to double check: you only load the tcp_rack. You don't run sysctl net.inet.tcp.functions_default=3Drack This means you load RACK, but you don't use it. What does "poudriere testport net/gitup" do? Only build stuff or does is also download something? What does bonnie++ do? Could you reboot the system, run the test, do kldload tcphpts, run the test again, do kldload tcp_rack, and run it again. I'm wondering if tcphpts is affecting the measurements... Thanks for testing.

This is interesting. It seems a consequence on loading TCPHPTS, not = actually using it. I have CCed Drew and Randall, who know much more about HPTS and might = have follow up questions.
