Dear users,
we have just released a hotfixed version of Knot DNS. These last changes
address several issues:
- The last release slowed down the compilation a lot, due to some
changes in underlying code. This has been improved, so that the
compilation should be as fast as before.
- It turned out that Knot DNS was applying ENDS0 UDP payload limit also
to TCP queries - we are sorry for such a bug, it should be OK now.
- Besides, a missing include for FreeBSD was added and a potential crash
with many concurrent transfers was fixed too.
Source files can be downloaded here:
http://public.nic.cz/files/knot-dns/knot-1.0.3.tar.gz
Packages will be available soon on http://www.knot-dns.cz
Next version is due to be released in a short time, featuring support
for new RR type TLSA (52).
Enjoy!
Lubos
Hello, list!
I encountered a problem when I tried to start Knot on FreeBSD 8.0.
When I tried start from rc.d script, Knotc freezed for 5 minutes until I
killed it.
When I tried "knotc start" nothing happened.
And when I tried start directly knotd, the following was happened:
dnssec-slave2# knotd -c /srvs/knot/etc/knot.conf
Reading configuration '/srvs/knot/etc/knot.conf' ...
Assertion failed: (knot_node_new_node(knot_dname_node(dname)) != NULL),
function xfrin_switch_node_in_dname_table, file libknot/updates/xfr-in.c,
line 2264.

configuration options, log messages and slightly optimized overall
performance.

Hello knotty people ;)
Both userspace-rcu and knot are now in the FreeBSD ports collection.

Hi:
I'm trying to test Knot 1.0.1 with a basic configuration, and I managed
to crash it.
Compiled from source on a Ubuntu 11.04, serving one signed zone.
uname -a
Linux turista 2.6.38-13-generic-pae #55-Ubuntu SMP Tue Jan 24 15:54:51
UTC 2012 i686 i686 i386 GNU/Linux
autoreconf -if
./configure --prefix=/opt/knot
make
sudo make install
The configuration file looks like this
system {
identity "knot 1.0.1";
storage "/opt/knot/var/knot";
}
interfaces {
my-iface { address 192.168.22.152@53; }
}
zones {
co.nz {
file "/opt/knot/etc/co.nz";
}
}
log {
syslog { any warning, error; }
}
Then
root@turista:/opt/knot# sbin/knotc -c etc/knot.conf compile
Parsing file '/opt/knot/etc/co.nz', origin 'co.nz.' ...
Compilation successful.
root@turista:/opt/knot# sbin/knotc -c etc/knot.conf -i start
control: Running in interactive mode.
Reading configuration '/opt/knot/etc/knot.conf' ...
And when I send a query to the server
dig dnskey co.nz @192.168.22.152
I get this in syslog
Mar 15 17:00:44 turista kernel: [1487877.778230] knotd[6010]: segfault
at 0 ip (null) sp b489e03c error 14 in knotd[8048000+50000]
The error is consistent. If I restart the server, wait a little bit to
load, and then send the query, it crashes.
Running under gdb provides the following backtrace
(gdb) bt
#0 0x00000000 in ?? ()
#1 0x0804f2d4 in udp_master_recvmmsg (thread=0x850b5f0, thread_stat=0x0)

#2 0x0804f6f6 in udp_master (thread=0x850b5f0)
at knot/server/udp-handler.c:526
#3 0x08085adc in thread_ep (data=0x850b5f0) at knot/server/dthreads.c:160

#5 0xb7d999ee in clone () from /lib/i386-linux-gnu/libc.so.6
If you need anything else, please let me know. Unfortunately I can't
send you the zone.

Hello,
Congratulations to the release of Knot 1.0 which I'm looking at a bit
now, starting off with a minimal configuration.
system {
storage "/etc/knot";
user: "root";
}
interfaces {
ipv4 { address 127.0.0.1@53; }
}
keys {
my-key hmac-md5 "xxxx";
}
remotes {
local0 { address 127.0.0.1; }
mastr { address 192.168.1.145; }
m2 { address 192.168.1.53; key my-key; }
}
zones {
example.com {
file "example.com.zone";
}
inline.aa {
file "inline.aa";
semantic-checks off;
xfr-in mastr;
notify-in mastr;
}
jpmens.net {
file "jpmens.net";
semantic-checks off;
xfr-in m2;
notify-in m2;
xfr-out local0;
}
}
Apologies for nitpicking on these rather cosmetic issues, but maybe they
can be addressed in a future version:
An invocation of `knotc -c knot.conf compile' complains that slave zone
files don't (yet) exist. (True enough: they haven't yet been
transferred):
Zone file 'inline.aa' doesn't exist.
Zone file 'jpmens.net' doesn't exist.
Parsing file 'example.com.zone', origin 'example.com.' ...
Compilation successful.
After launching Knot with `knotc -c knot.conf start', zones are
populated from the master server(s) and I see the *.db and *.db.crc
files. The zones are loaded and I can query them. So far, so good. :)
A small change to `example.com.zone' and a compile, again warns that the
slave zone files don't exist. In effect it is true: the filenames I've
configured in knot.conf do not exist, but the message is confusing
because the zones have been loaded/exist.
knotc -c knot.conf compile
Zone file 'inline.aa' doesn't exist.
Zone file 'jpmens.net' doesn't exist.
Parsing file 'example.com.zone', origin 'example.com.' ...
Compilation successful.'
A subsequent server reload `knotc -c knot.conf reload' says in the log
that the file(s) I just compiled are out of date:
Loading 3 compiled zones...
warning: Database for zone 'example.com' is not up-to-date. Please recompile.
Loaded zone 'example.com.'
Zone 'inline.aa.' is up-to-date, no need for reload.
Zone 'jpmens.net.' is up-to-date, no need for reload.
Loaded 3 out of 3 zones.
Configuration reloaded.

-JP

Hi,
a (mostly) bugfix release of Knot DNS was made today (v. 0.9.1).
Corrected issues:
- Fixed build on BSD.
- Fixed parsing and dumping of some types (IPSECKEY, WKS, DLSV, APL,
SPF, NSAP).
Moreover, we added RRSet round-robin rotation when answering and a new
pseudo-random number generator.
Source files can be downloaded here:
http://public.nic.cz/files/knot-dns/knot-0.9.1.tar.gz
Packages will follow shortly (probably tomorrow).
Enjoy and be ready for the 1.0 release, which is on the way!
Kind regards,
Lubos
