Why was 1.3.0 an oddball release?

January 31st, 2020

1.3.0 was an oddball release because I applied to funding from the federal german government in a program called, shifting the release date early by half a year. I didn't get selected with delphinusdnsd. Meaning, I paid out of my own pocket to work on version 1.4.0 and 1.4.1 (January 2019 through February 2020). In 2018 between summer and christmas I had another project (OpenBSD powerpc64 port which ultimately failed) while waiting on the selection results of prototypefund. All releases before 1.3.0 were also constructed from my spare time as I could find it. I'm glad 1.4.X is out and I'm looking forward to programming on 1.5.0 (expected to be released in late December). Someone I met is working on an OpenBSD port for me and I'm looking forward to featuring him on the Credits section of the site once the work is committed at OpenBSD. The porting work is no easy feat and I'm glad someone is doing this for me.


Delphinusdnsd 1.4.1 to be released in February

January 26th, 2020

I believe the fixes I made to delphinusdnsd (on linux) were good. I'm going to backport the code to the STABLE_1_4 branch soon and then tag it RELEASE_1_4_1. I'm gonna run the code as it is now for another week on the particular Linux computer that had problems throughout december and early january and if I don't see any more crashes then it's a done deal. Sorry for inconveniences. This I believe did not affect BSD versions of this code, only Linux although and off-by-one was fixed (I think), that should have impact on all platforms.


Something is wrong with delphinusdnsd 1.4 (on linux)

January 9th, 2020

Sorry to bring these bad news... I have noticed segfaults on Linux but not on OpenBSD, in the TCP engine (tcploop()). I have for the time being reinstalled nsd on the linux replicant and I'll have to see what's causing this. I know of one possible off-by-one buffer overflow but I couldn't exploit it with my test program. I'm still looking. I suspect that the problem may be with the linux TAILQ macros as I remove a member from the tailq and it wasn't _SAFE (which is only found in libbsd) so there is some room for corruption there. I'll look at replacing the TAILQ macros with their libbsd equivalents for 1.5.0 and possibly backport it to 1.4.1. Still deciding what to do and how to it correctly. I haven't seen the OpenBSD delphinusdnsd with this behaviour, and that is what I care most about.


Delphinusdnsd 1.4.0 Released

January 2nd, 2020

I have released delphinusdnsd 1.4.0. More info is found in the news.html entry. I'd like to thank everyone that contributed to this release (special thanks to FreeLogic and PiRATA).


Recent modification fixes answers for PowerDNS recursors

December 27th, 2019

Revision 1.98 of reply.c does more reply length checks and truncates when appropriate. Before it gave weird answers because it excluded RRSIG's and fit NSEC3's which was bogus. PowerDNS recursor noticed this as bogus and would mark all zones on those nameserver as bogus (as tested). Of course PowerDNS was right in this, and my code was wrong. Much thanks to Peng_ in #dns on freenode who helped me debug this problem.


1.4.0 Release in January after all

December 26th, 2019

I found some problems with delphinusdnsd and I'd like a week of testing before tagging it a release. I'm hoping for a release around or on January 2nd, 2020.


Last patch was wrong

December 22th, 2019

Sorry to bother you again, the last patch was wrong, I had edited the article directly but you wouldn't see it if you didn't reload it. Here it is again.

Security problem identified

December 22nd, 2019

Here is a patch, if you're using the daemon. Unfortunately this won't be available until the release day. I'm mindsearching if I'm going to put this release off until next year (2020).


Wishing you a happy time

December 20th, 2019

I'd like to wish you a happy december solstice and a merry christmas. I'm going away for 6 days from my work setup until the 26th when I'll be back in my apartment and doing the final check for delphinusdnsd and then releasing it.


Three days of testing remain

December 19th, 2019

Today I installed NetBSD and noticed I don't really know too much about this BSD. It was sorta hard. But I finally managed to install Delphinusdnsd to it and it prompted for some makefile changes. So then I'll be revisiting all test platforms tomorrow and on the 26th and 27th after which I will tag a release in the tree and make the tarball available. Unfortunately christmas is in the way or else I'd have a few more days. And commitments after the 27th until new years take away also a few more days. If you want to try out Delphinusdnsd grab a snapshot and test. It's likely not going to change in a big way in these last three days. If you'd rather wait for the 1.4 tarball, there is eight days left to wait for that.
