  systemd-resolved emits a disturbingly large amount of NXDOMAIN log
  messages that do not actually indicate any real problem

  [test case]

  see original description, or look at any log from any recent Ubuntu
  system, or search google for endless complaints about NXDOMAIN
  messages logged by Ubuntu

  [regression potential]

  any regression would likely be isolated to systemd-resolved handling
  of a NXDOMAIN response from its upstream nameserver, including
  possibly failing to resolve a hostname or delays in resolving
  hostnames

  this is needed for all releases; the patch is not upstream, but
  carried by Ubuntu

  I normally don't like this, but it's a one-character change so it's
  easier to start with the solution:

  Making this name absolute instead of relative avoids spurious
  resolutions of "connectivity-check.ubuntu.com.your_domain." This
  removes a fair amount of NXDOMAIN error noise in journalctl.

Bug description:
  [impact]

  systemd-resolved emits a disturbingly large amount of NXDOMAIN log
  messages that do not actually indicate any real problem

  [test case]

  see original description, or look at any log from any recent Ubuntu
  system, or search google for endless complaints about NXDOMAIN
  messages logged by Ubuntu

  [regression potential]

  any regression would likely be isolated to systemd-resolved handling
  of a NXDOMAIN response from its upstream nameserver, including
  possibly failing to resolve a hostname or delays in resolving
  hostnames

  [scope]

  this is needed for all releases; the patch is not upstream, but
  carried by Ubuntu

  [original description]

  I normally don't like this, but it's a one-character change so it's
  easier to start with the solution:

  diff -u -r1.1 /usr/lib/NetworkManager/conf.d/20-connectivity-ubuntu.conf
  --- /usr/lib/NetworkManager/conf.d/20-connectivity-ubuntu.conf
  +++ /usr/lib/NetworkManager/conf.d/20-connectivity-ubuntu.conf
  @@ -1,2 +1,2 @@
   [connectivity]
  -uri=http://connectivity-check.ubuntu.com/
  +uri=http://connectivity-check.ubuntu.com./

  Making this name absolute instead of relative avoids spurious
  resolutions of "connectivity-check.ubuntu.com.your_domain." This
  removes a fair amount of NXDOMAIN error noise in journalctl.

  Observing the issue and the fix requires 3 terminals:

  1. tcpdump -i any 'port domain'
  2. journalctl --boot -u systemd-resolved -f

  3. nmcli c down "Wired connection 1"; nmcli c up "Wired connection 1"
   => observe the NXDOMAIN noise over a couple few minutes

  Now make the hostname absolute with the trailing dot above and run:
     systemctl reload NetworkManager
  Wait 1 min for things to stabilize. Test again:

  nmcli c down "Wired connection 1"; nmcli c up "Wired connection 1"
   => observe non-zero but significantly reduced NXDOMAIN noise over a couple 
few minutes

2021-01-22 Thread rjc
I just upgraded two machines to Ubuntu 20.04 LTS and /var/log/syslog is
full of:

systemd-resolved[...]: Server returned error NXDOMAIN, mitigating
potential DNS violation DVE-2018-0001, retrying transaction with reduced
feature level UDP.

with the only thing reported by tcpdump(8) as:

[...] [udp sum ok] 9797 NXDomain* q: ? connectivity-
check.ubuntu.com.[...]

The only thing that fixes it is by making connectivity-check.ubuntu.com
fully qualified.

I have over 250 machines to upgrade. It all adds up.

Please append the dot.

2020-07-30 Thread MarcH
I ran tcpdump 'host ubuntu20 and port domain' on my router and looked at
all the other NXDOMAIN at boot time besides this one.

1. PTR request on the IPv4 address of my virbr0 interface. Gone after
uninstalling a couple libvirt-* packages

2. PTR request on ONE of my IPv6 addresses. It's not obvious to me which
address gets picked for that PTR query. I disabled IPv6 ULA on my router
and the PTR request just moved to a different address.

3. SOA local. ??


I also found that NetworkManager needs to be told 
"connectivity-check.ubuntu.com has no  record" about 12 times during boot, 
that seems a bit excessive? (this is not NXDOMAIN)

2020-07-28 Thread MarcH
> the vast, VAST majority of the time you see this message it is

I don't have any extensive data as you seem to have but _for me at home_
(= office now!) and without zero captive portal involved, adding this
trailing dot reduces the NXDOMAIN frequency from one message every 5
minutes to a few messages _per day_ (NM's default interval is 300
seconds)

The "journalctl --boot -p notice" total also becomes about twice
smaller. I filed this bug for a reason.


> the NXDOMAIN returned by the upstream nameserver is the *correct* response -

Yes of course, hence this one character fix which IMHO also removes one
large "distraction" from the main, captive portal issue!


> if you see this NXDOMAIN "error" [outside a captive portal] it is almost 
> always just a normal lookup of a domain that doesn't exist,

... which is for sure very rare on my (admittedly headless) system. Not
sure why querying inexistent domains would be frequent on others'
systems?

> and the error message is simply wrong

It says "mitigating _potential_..." so it's not strictly speaking wrong.
Agreed it can be misleading but summarizing this fairly complex issue in
just one line is quite a challenge.


> This is due to a Ubuntu-only patch to systemd 

Care to share the "best" link(s) about this? I mean links to best bugs
and/or relevant source code. An internet search returns too many hits!
BTW a good and authoritative bug number in the error message would
probably not hurt either, see why above.


> network-manager could work around this problematic Ubuntu-only systemd patch,

With an Ubuntu-only network-manager patch maybe? Sorry couldn't resist
:-)

2020-07-28 Thread Dan Streetman
> One thing that would help with these confusing NXDOMAIN errors in
general

the vast, VAST majority of the time you see this message it is actually
not a NXDOMAIN error. This is due to a Ubuntu-only patch to systemd to
work around some select captive portals that are slightly broken, so in
any environment outside the broken captive portals (e.g. public wifi
that you have to 'click here to accept terms' before getting internet
access - and note that not all captive portals are broken) if you see
this NXDOMAIN "error" it is almost always just a normal lookup of a
domain that doesn't exist, and the error message is simply wrong (this
also slows down dns due to forcing fallback to a lower dns protocol
level and retry of the already-failed lookup).

To clarify specifically for this bug, the lookup of "connectivity-
check.ubuntu.com.your_domain" clearly has nothing to do with any "DNS
violation", and the NXDOMAIN returned by the upstream nameserver is the
*correct* response - that hostname really, actually doesn't exist.

network-manager could work around this problematic Ubuntu-only systemd
patch, but the real problem is unquestionably that systemd should not
have the Ubuntu-only patch that's causing these messages.

Fixing this appropriately (i.e. so that systemd still works with the
broken captive portal issue) requires access to one of the broken
captive portals, so I haven't been able to work on correctly fixing this
lately, but it is something I want to do, so we can get rid of the very
unfortunate false NXDOMAIN "error" messages.

> systemd behaviour could be better for domains without '.'

One thing that would help with these confusing NXDOMAIN errors in
general (not just from NetworkManager) is for systemd to provide a more
verbose and possibly less "private"[*] mode that shows the requested
domains somewhere without having to use tcpdump on the side and try to
match timestamps, process IDs and what not. In fact this mode could be
considered "more secure" because of the added admin transparency. It
could be off by default for privacy reasons - depending on where the
information goes.

Maybe this more verbose mode exists and I missed it? Or a feature
request already filed? In either case please share, thanks.

systemd behaviour could be better for domains without '.'
however, that is considered low, in the light of network-manager fix.

Imho network-manager fix should be SRUed, do you agree? And it would be
on the desktop team to do so, right?

  Making this name absolute instead of relative avoids spurious
  resolutions of "connectivity-check.ubuntu.com.your_domain." This
  removes a fair amount of NXDOMAIN error noise in journalctl.

  
  Observing the issue and the fix requires 3 terminals:

  1. tcpdump -i any 'port domain'
  2. journalctl --boot -u systemd-resolved -f

  3. nmcli c down "Wired connection 1"; nmcli c up "Wired connection 1"
   => observe the NXDOMAIN noise over a couple few minutes
   
  Now make the hostname absolute with the trailing dot above and run:
 systemctl reload NetworkManager
  Wait 1 min for things to stabilize. Test again:

  nmcli c down "Wired connection 1"; nmcli c up "Wired connection 1"
   => observe non-zero but significantly reduced NXDOMAIN noise over a couple 
few minutes

  Plenty of people annoyed by NXDOMAIN warnings, just Google it.
