[Cerowrt-devel] Names not resolved on Wireless

[Fred Stratton]

True for the last two builds. Wired works as expected.

Is this a problem with the development version of DNSMasq? What is the recommended workaround?

I can confirm it as well. I wiped my config back to defaults, and it wasn't
fixed. Reinstalled the 3.10.11-3 build, and restored my configs and all is
well.

Just tested again with 3.10.15-2. My OSX (10.8.5) laptop worked, neither my
Nexus 7 (2013 w/CM10.2) or my Fedora 19 laptop could resolve DNS over
wireless. My wired Linux server (Ubuntu 12.04.3) was working fine as well.
Reverted to 3.10.11-3 once more.

Re: [Cerowrt-devel] Names not resolved on Wireless

Dear Dr. Dnsmasq:

When cerowrt made the jump between dnsmasq-2.67-test10 and
dnsmasq-2.67-test17, detection of interfaces other than the first
started failing. It seems to be related to interfaces that come up
after dnsmasq starts, as restarting it after the device is fully
booted works. Have moved forward to 2.67-rc3 to no avail.

(along the way we migrated from kernel 3.10.11 to 3.10.13 to 3.10.15
but I doubt that's the issue)

Hot, fresh, firmware can be had at:

http://snapon.lab.bufferbloat.net/~cero2/cerowrt/wndr/


<knacky> [10:39:25] has anyone had IPv4 DHCP problems in the last two 3.10.x
builds?  currently running 3.10.11-3 and it works flawlessly.
upgraded to 3.10.13-2 and 3.10.15-1 and both present me with an
identical issue.  upon reboot after upgrading, DHCP leases are no
longer handed out on the wireless interfaces.  disabling and
re-enabling DHCP on the wireless interfaces will fix the problem, but
the problem
<knacky> [10:39:26] returns after a reboot.  disable/reenable DHCP on the
interface will again temporarily fix it.
<knacky> [10:42:03] also tried a fresh install (using reset to defaults
option) to avoid anything not properly interpreted from the config of
the previous version, but still get the same issue.

Re: [Cerowrt-devel] Names not resolved on Wireless

[Fred Stratton]

With the last three builds, there is no ipv4 connection to OS X 10.7.5 or Ubuntu 12.04.3 clients. ipv6 works, but that is not the responsibility of DNSMasq yet, IIRC. Attempts at ipv4  lease renewal fail on both clients.

Have reverted from 3.10.15-2 to 3.10.11-3 again, awaiting another build of DNSMasq.

Seems likely.

I reverted that patch and put it in this build

http://snapon.lab.bufferbloat.net/~cero2/cerowrt/wndr/3.10.15-3/

I won't be in a position to test stuff myself til sunday but cero's
devoted userbase seems to be hoovering over the reload button and will
probably beat me to it....

Uh oh… It looks as if 3.10.15-2 is identical to 3.10.15-3 on the download pages. 

http://snapon.lab.bufferbloat.net/~cero2/cerowrt/wndr/3.10.15-3/

I downloaded both (…15-2 and…15-3) and they're the exact same length, and the firmware that's identified as the -3 version displays "-2" in luci...

Best,

Re: [Cerowrt-devel] [Dnsmasq-discuss] Names not resolved on Wireless

[Simon Kelley]

I'm not sure that's the problem, but it's worth a try.


Another thing to do is add a a line to log if bindtodevice() in 
src/dhcp-common.c actually sets the SO_BINDTODEVICE sockopt. It's not 
supposed to even is there's currently exactly one interface, if there's 
a possibility that more will appear. This could be relevant in this 
case, but I'm not sure where the regression could come from.

Hmm, are you using --listen-address or --interface to configure dnsmasq 
to server particular interfaces? Or maybe --except-interface? Now 
there's a thought.....

Simon.

Re: [Cerowrt-devel] [Dnsmasq-discuss] Names not resolved on Wireless

[Simon Kelley]

Having thought about this more, this patch is necessary

http://thekelleys.org.uk/gitweb/?p=dnsmasq.git;a=commit;h=8584c502d37627d8abe18213771b5f4f98cb4aa3

and should fix the bug iff

1) Dnsmasq is configured using --except-interface=<upstream interface> 
and there are no --interface=<interface we want to provide service on> 
config lines.

2) Exactly one interface that dnsmasq should be listening on is around 
when it starts, but others arrive later.

I can't explain why it just broke though, this bug has been around forever.


Simon.

Re: [Cerowrt-devel] Names not resolved on Wireless

[Fred Stratton]

You are correct.

3.10.15-3 does not remedy the issue with wireless dhcp clients.

I just pushed to git code to log at startup if dnsmasq deploys the 
SO_BINDTODEVICE hack. The compile-time and run-time dependencies to do 
that were frightening. Given that this can and has silently bitten 
people, it's good to be informed.

If you see something like

dnsmasq-dhcp: DHCP, sockets bound exclusively to interface br0

then there's a problem.


I'll try and learn how to flash the router Dave gave me so I can test 
this stuff myself.

Cheers,

Simon.

Re: [Cerowrt-devel] [Dnsmasq-discuss] Names not resolved on Wireless

[Richard E. Brown]

Simon,

> I'll try and learn how to flash the router Dave gave me so I can test this stuff myself.

For anyone interested in trying to do this at home, Dave wrote a *very* good procedure for flashing the ...xxx-squashfs-factory.img firmware via tftp at:

http://www.bufferbloat.net/projects/cerowrt/wiki/CeroWrt_flashing_instructions

As noted on that page, the tftp process always works. You'll also need:

- bent paper clip
- Ethernet cable
- tftp client on your computer
- and of course, a WNDR3700v2 or WNDR3800 router

It takes longer to read the steps than to flash the firmware. :-)

Reverted DNSmasq to 2.67test10* as suggested. Still no ipv4 addresses. Reverted to 3.10.11-3 again. Checked settings. Renewed leases. Rebooted everything.

Indeed. Being located in a nautical, rather than office, environment I 
used a split-pin instead of a paperclip. I also had to find the firmware 
for the ethernet port in the ship's computer, which is not supported 
out-of-the-box by Ubuntu :-( That done, it went fine.

Poking around my newly flashed router, I find.

1) The dnsmasq config does indeed use --except-interface and no 
--interface statements, so the SO_BINDTODEVICE bug a talked about before 
may have caused the problem if exactly one interface is up when dnsmasq 
starts. The code I committed yesterday which logs setting 
SO_BINDTODEVICE is the final arbiter of this, but I think that bug 
should be fixed anyway. It may have been the original source of the problem.

2) This is an out-of-the-box router, I've not changed the config at all. 
I can see a single --dhcp-range, 
172.30.42.2,172.30.42.27,255.255.255.224,24h which corresponds to the 
wired interface. I can't see anything for the wireless interfaces. When 
I go to the GUI for the wireless interface, I see it has address 
172.30.42.65/26 and the DHCP service is enabled, but for start address 2 
and 26 leases. Since 2 isn't in the 64-96 range, could that be the 
problem, or am I missing something obvious?

Cheers,

Simon.
