Page Faults in DMESG? (simple-adblock, dnsmasq, 17.01.0, WNDR3800)

Installing and Using OpenWrt
1

I woke up this morning to no internet. After trying to reboot the router and modem, which failed, I eventually logged in and pulled up my kernel log. If you look toward the bottom, it appears some sort of failure has occured. I have no idea what to do about it. Ideas?

WNDR3800 is s stable old device, so that looks a bit strange.
Just reboot the device, and hope that this time things keep running.

Note that the logged faults have happened right after the boot and then at every 6 seconds. So you should see rather quickly if the same happens again.

You might also try a newer 17.01 build. E.g. my community build for WNDR3700/3800 has a month newer version. Build for WNDR3700v1/v2 / WNDR3800

Simple Adblock was causing it. I turned it off and now it's working fine. The DNS errors tipped me off...

Thanks Hnyman. I have extra hardware, so maybe I'll load up your latest and check it out...

4

Interesting. "simple adblock" causing dnsmasq page faults? Might interest also @stangri

5

Thanks @hnyman, @motocrossmann. Could it be caused by a very large blocked domains list so dnsmasq was running out of RAM?

6

I'll try and test it later today and report back.

7

It doesn't appear to be out of memory, but here are the numbers. Let me know if there are other tests I should run, or logs to look at. As soon and I turn adblock on, the page faults appear. When I turn it off and restart, they are gone.

8

For what it's worth, here is the system log when I enable simple-adblock. This isn't an urgent issue for me, as my internet works fine when I turn adblock off.

There should be more entries in the log. It would also improve readability if you do logread -e simple.

11

Thanks! And the dnsmasq still segfaults?

12

At the time of that log, I did check dmesg and it was showing the page faults. What I don't know is whether or not adblock was always causing those errors or if it just started happening. I never looked at the kernel log until internet went down, which is when I started this thread.

13

I've implemented some changes in filtering and management of the dnsmasq-file in 1.5.7-1, please upgrade to this version (if you have my repo added to your router it's just opkg update; opkg upgrade simple-adblock) and let me know if that helps.

14

Hmm, I'm failing to get the repo added. I followed your package repo instructions, but got this:

Collected errors:

15

Are uclient-fetch and libustream-mbedtls installed?

16

Yup. I originally installed simple-adblock using an old procedure using wget, I think. I can't really find those old instructions as your readme appears to be updated.

17

Can you post opkg list-installed?
@hnyman -- may the opkg_download fail because it either can't or won't use wget/libopenssl combo?

Based on the installed package list, there is full wget, and both libopenssl and libmbedtls, so everything should be ok.

wget error 5 is "SSL verification failure."

When I try manually in a router without ca-certificates downloading with wget https://raw.githubusercontent.com/stangri/openwrt-repo/master/Packages.gz , I receive certificate check error: "Unable to locally verify the issuer's authority."

That is likely what is happening there. @stangri's repo at Github is https, and the cert verification fails due to missing certificates.

The same happens if I change a normal LEDE repo's address in /etc/opkg/distfeeds.conf to be https. opkg does not normally use https based repos, so opkg does not issue the "--no-check-certificate" parameter for wget. So, opkg expects "fully working https downloading functionality" if https links are used.

Two simple solution alternatives:

  • install ca-certificates package, so that SSL certificate verification succeeds.
  • manually download the simple-adblock related packages to /tmp and opkg install them. You can use wget --no-check-certificate https://github.com/stangri/openwrt-repo/blob/master/simple-adblock_1.5.7-1_all.ipk for downloading from Github

This worked! I no longer get the error when trying to run 'opkg update'. Thanks @hnyman!

@stangri, I'll test out 1.5.7-1 and report back later.
