Bind upgrade producing errors on pfsense 2.5 upgrade

@matthijs "Name Server" and "Base Domain IP" was the problem in my case.

matthijs

I cannot understand that is causing the issue in my case these fields will result in the following records in de zone file (fictional IP and FQDN)

@ IN NS nameserver.fqdn.com.
@ IN A 1.1.1.1

@matthijs

I did as shown in the video on YouTube https://www.youtube.com/watch?v=Sgn4oNy85_o&t=337s

@matthijs The video is a tutorial about configuring bind in pfsense and I just followed it while I looked at my config via the GUI. I wouldn't of even though some of the mistakes were mistakes. Like I put in the wrong base ip in the reverse zone and one of the reverse zones had localhost in the name of the nameserver and I changed it to 127.0.0.1. I cleared all the serial numbers so they were generated, probably no effect on that one. In my 2.16.172 reverse some I changed the first record from 1.2.16.172 to 1 PTR pfsense.localdomain. I increased the the Memory limit in the main config from 256M to 1024M, now that could of had an effect. Most of it was just little differences and all of the changes were made with the GUI.

Here's a diff of the bind part of my backed up config...

Well that didn't turn out like I hoped but I deleted a couple of things too.

Been marked as a spammer so I can't edit the previous entry. Note that you can turn off zones and that may help in debugging. Just go to the little box at the beginning of the zone and disable it and see if it stops crashing.

Hi!

Could the usage of an additional ACL cause the problem?

Debian Discussion: Bug#980786: named: after upgrade to bind9=1:9.16.11-1 named is killed with status=11/SEGV

nordeep

@freebsd-man Thanks. It's make sense.

madforic

@freebsd-man That is the issue!
In my case I disabled any named acl and bind started as expected.
Named acls make sense only for master zones. Slave and forward zones works with named acls without proplems.

matthijs

Is there maybe a way to workaround for this ACL issue ? I have two ACLs and I really need them (one is an ACL containing secondary name servers who are allowed to do zone transfers, the other is an ACL containing hosts who are allowed to do dynamic updates)

Or should I wait till this bug is fixed and a new release is provided ?

I'm not sure if I have the same issue, but after upgrading to 2.5.0, named service, along with several other downloaded packages, fail to start upon reboot. A manual start of the named service clears the blockage and all the other services then proceed to start normally.

No logs whatsoever are saved on the first (automatic) start attempt. Afterwards, no error is shown, I've tried to delete my only named ACL, but the problem persists. Reinstalling the Bind package is also of no use.

Any hints on how I could debug this further would be appreciated.

matthijs

I read that this Bind bug (bug 980786) where freebsd-man is referring to is already fixed.
Can Netgate update the Bind package to the latest version?

viktor_g

try to update it directly (on x86):

# pkg add -f https://pkg.freebsd.org/FreeBSD:12:amd64/latest/All/lmdb-0.9.28,1.txz
# pkg add -f https://pkg.freebsd.org/FreeBSD:12:amd64/latest/All/bind916-9.16.12.txz

freebsd-man

@viktor_g :
With the BIND 9.16.12 package I can use an ACL without issues in a view and zones.

The LDAP package is a needed dependency for installing the bind package this way.
I think the final updated pfSense package will perhaps also have this dependency or will be a modified package without it.
So I will delete both packages before updating bind via pfSense GUI.

@viktor_g
I've updated to the 9.16.12 version and my problem persists, so this is clearly not related. Maybe I should open a support ticket?

matthijs

I updated directly to bind916-9.16.12 from the command line like viktor_g suggested, and all my Bind problems are SOLVED :-) , bind starts and runs without issues now. Can Netgate update the official Package Manager with bind916-9.16.12 ?

Thanks in advance

@viktor_g
Confirm. After manual update bind to 9.16.12 issue has been solved, in my case.
Thank you!

freebsd-man

After deleting the manual installed bind and lmdb packages und the old pfSense -pkg-bind package via shell, I installed the updated Package pfSense-pkg-bind-9.16_10 via GUI.

While installing I used "tail -f /var/log/resolver.log" to inspect the startup of the new bind.

I got rndc timeout messages from install log in GUI and errors from bind-startup in tail-output.
After GUI timouts the install finished successful.

After deleting corrupted journal files with "rm /cf/named/etc/namedb/*jnl" I finally was able to start bind via GUI.
Now it is up and running.

@freebsd-man
In my case, upgrading the Bind package did not solve the problem. I get the same timeouts at install, but also during startup. I've deleted all the files and reinstalled the package, but it didn't make any difference.

What I've found out is that given enough time (like 15-20 minutes in my case) the named service will eventually start, but not before cycling through each of the zones trying to freeze and thaw them and getting timeouts from RNDC. There are no logs of this, but I can see the processes in memory:

/usr/local/sbin/rndc -q -c /usr/local/etc/rndc.conf freeze [zone name] IN [view name]
/usr/local/sbin/rndc -q -c /usr/local/etc/rndc.conf thaw [zone name] IN [view name]

It's definitely a problem with RNDC, but I can't figure out how to fix it, I guess I'll just have to go back to 2.4.5, since I'm apparently the only one experiencing this issue.
