I am running 95 and have had two times in the past couple of weeks where dnsmasq has died on me. I have been able to fix the problem by starting it up again and it works just fine.
The error appears to be associated with these log entries:

this is a fresh install of IPFire 94, then upgrade to 95. Please let me know what I can do to further troubleshoot this.

Hi,
yes, dnsmasq has some stability issues. This has become way better since a few releases, but it is still not at the level where it should be.
Have you any information about how to reproduce the crash? I experienced them for a time, but they were all random and I could not debug this a lot.
I just merged a patch with some fixes. Maybe it has been fixed in there. Please test Core Update 96 as soon as it becomes available for testing.
Best, -Michael

I tried to reproduce it, but was not successful. I saw no correlation between the two times it happened. If it breaks again, I'll see if I can create a conditions list, however.
My office firewall is set to always run the testing tree, so as soon as 96 goes into beta, it will automatically upgrade (I keep a very, very old router around in case I completely mess it up with the upgrade! ).
I really hate giving a report that says "this broke." I know you need more information than that.

Just a follow up on the dnsmasq issue. It happened again tonight, with logs similar to what I had before. See at the bottom. Here is the sequence of events:
I was opening http://news.bbc.co.uk (which redirects to http://www.bbc.com/news). It made it halfway through the page when dnsmasq apparently died (some of the images did not come up). I then tried to open a few additional pages, all at www.bbc.com, and when they all failed, I checked the server. Note that at 21:53:13 it was running fine, and at 21:54.25 it died, during a page load.
Just prior to all this, I had loaded several pages, each requiring a DNS operation. It appeared dnsmasq died during the loading of the last of them (news.bbc.co.uk) as that one had images only partially complete. The sites were.
http://antwrp.gsfc.nasa.gov/apod/ http://news.bbc.co.uk/ http://www.publicbroadcasting.net/kera/news.newsmain http://planet.ipfire.org/ http://www.kyivpost.com/
I tend to open these all at the same time in Firefox and they generally work just fine. At the time I opened these, I also had 12 other tabs open in three additional instances of Firefox, one tab open in Chromium, my mail client open with 4 accounts. No other machines were on in the location.
I see no patterns at all. The last time it happened, I do not believe I had nearly as many sessions open (there are always around 12 web pages open in two Firefox windows). It is weird in that it happened about a week ago also.
The IPFire machine is as follows: AMD Geode, single core, 500Mhz 512M RAM, no swap 4 VIA VT6105M NIC's, Red, Green and two bridged Green 1 TP-Link TL-WN75IND wireless PCI card (Qualcomm Atheros AR9227 Wireless NIC)
With the exception of bridging two NIC's into the Green, and the wireless NIC, this is a standard configuration I have used in dozens of firewalls.
Michael, does any of this match your machine that has had the issue? Do you think I should look for anything else, or do you want to just wait for Core 96 and see if the new dnsmasq fixes it.

HI,
if you'd like to test the latest 'dnsmasq 2.75', containing the "latest upstream patches" I could send you the download link of the version which is now running for about two weeks here without any crashes. Besides, using DNS.WATCH-servers, I never had any crashes, but it could be worth a try.
I'm just not really sure - this version was compiled an an "Intel Core 2 Duo" - is this ready for "AMD Geode" or do you need a somewhat ~special version!?
Regards, Matthias

I have pretty much the same situation here, but on various machines and even on virtual machines.
However I was not able to reproduce it with a single DNS record. It rather seems to be that if there are a few DNS queries coming in at the same time, dnsmasq tends to crash under certain circumstances. The only thing that I can do is contacting upstream again and raise attention, but I am not sure if they can do anything if we cannot show when the crash is happening.

I tried to reproduce it, but was not successful. I saw no correlation between the two times it happened. If it breaks again, I'll see if I can create a conditions list, however.
My office firewall is set to always run the testing tree, so as soon as 96 goes into beta, it will automatically upgrade (I keep a very, very old router around in case I completely mess it up with the upgrade! ).
I really hate giving a report that says "this broke." I know you need more information than that.

Hi,
yes, dnsmasq has some stability issues. This has become way better since a few releases, but it is still not at the level where it should be.
Have you any information about how to reproduce the crash? I experienced them for a time, but they were all random and I could not debug this a lot.
I just merged a patch with some fixes. Maybe it has been fixed in there. Please test Core Update 96 as soon as it becomes available for testing.
Best, -Michael

I am running 95 and have had two times in the past couple of weeks where dnsmasq has died on me. I have been able to fix the problem by starting it up again and it works just fine.
The error appears to be associated with these log entries:
Nov 24 13:38:26 dd-router kernel: dnsmasq[2789]: segfault at 0 ip 0805daaf sp 5af771e0 error 4 in dnsmasq[8048000+32000] Nov 24 13:38:26 dd-router kernel: grsec: Segmentation fault occurred at (nil) in /usr/sbin/dnsmasq[dnsmasq:2789] uid/euid:99/99 gid/egid:40/40, parent /sbin/init[init:1] uid/euid:0/0 gid/egid:0/0 Nov 24 13:38:26 dd-router kernel: grsec: bruteforce prevention initiated due to crash of /usr/sbin/dnsmasq against uid 99, banning suid/sgid execs for 15 minutes.

this is a fresh install of IPFire 94, then upgrade to 95. Please let me know what I can do to further troubleshoot this.
