2020-08-11 Thread Gianfranco Costamagna 
just to clarify, the change is in bind9-libs and fixes the issue also
for my servers.

the change
+--- bind9-libs-9.11.16+dfsg.orig/lib/isc/unix/socket.c
 bind9-libs-9.11.16+dfsg/lib/isc/unix/socket.c
+@@ -4050,7 +4050,7 @@ check_write:
+   if (!SOCK_DEAD(sock)) {
+   if (sock->connecting)
+   dispatch_connect(sock);
+-  else
++  else if (!sock->pending_send)
+   dispatch_send(sock);
+   }
+   unwatch_write = true;


doesn't change the ABI/API of the library, so no-change rebuilding isc-dhcp 
package against the fix is not useful.

[Touch-packages] [Bug 1872118] Re: DHCP Cluster crashes after a few hours

2020-08-06 Thread Jorge Niedbalski 
Hello Andrew,

I just reviewed the core file that you provided. Thread 1 is the thread that 
panics
on assertion because sock.pending_send is already set. This is the condition I 
prevented
in the PPA, so *shouldn't* be hitting the frame 3

In my test systems I don't hit this condition, dispatch_send isn't called if 
pending_send
is set.

Andrew, what's the current version of libisc-export1105:amd64 installed in your 
system? can you provide a dpkg -l output and a systemctl status for the dhcpd 
service? Did you restarted/killed the dhcpd processes after upgrading that 
library?

Thanks in advance.

[Touch-packages] [Bug 1872118] Re: DHCP Cluster crashes after a few hours

2020-08-04 Thread Richard Laager 
I ran:
sudo apt install \
isc-dhcp-server=4.4.1-2.1ubuntu6~ppa1 \
libdns-export1109=1:9.11.16+dfsg-3~ppa1 \
libirs-export161=1:9.11.16+dfsg-3~ppa1 \
libisc-export1105=1:9.11.16+dfsg-3~ppa1 && \
sudo systemctl restart isc-dhcp-server

The restart at the end was just for extra good measure, to make sure I
was running on the new libraries.

I'm coming up on 3 hours running, which is a good sign.

Andrew,

Thank you for your input.

** Do you have any logs or a crash report to take a look after you
upgraded these systems?

On my test lab , I am counting for 3+ hours without a crash.

[Touch-packages] [Bug 1872118] Re: DHCP Cluster crashes after a few hours

2020-08-04 Thread Andrew Welham 
isc-dhcp-server failed to start after that, a reboot fixed it and it appeared 
to stabilise. Then as a test i upgraded the primary server.
when the primary server came on line the secondary went off line and the 
stability of the environment went down fast. 
Remove the patched version and installed the version from 18.04 to be able to 
stay online

2020-08-04 Thread Jorge Niedbalski 
Hello Andrew,

Correct me if I am wrong but it seems your system isn't running with
libisc-export1105:amd64 1:9.11.16+dfsg-3~ppa1 (?)

I am running the following packages from the PPA, please note that 
libisc-export1105 is required (that's
where the fix is located).

root@dhcpd1:/home/ubuntu# dpkg -l | grep ppa1
ii isc-dhcp-server 4.4.1-2.1ubuntu6~ppa1 amd64 ISC DHCP server for automatic IP 
address assignment

I'll leave this running until I can reproduce the crash or assume that the fix
works.

Please let me know if you can reproduce with those packages.

Thanks,

[Touch-packages] [Bug 1872118] Re: DHCP Cluster crashes after a few hours

2020-08-04 Thread Jorge Niedbalski 
Hello Andrew,

The fix is on the libisc-export1105 library (check dependencies on: 
https://launchpad.net/~niedbalski/+archive/ubuntu/fix-1872118/+packages), just 
replacing
the dhcpd binary won't be enough.

If you can install isc-dhcp-server and its dependencies from the PPA and
test, would be great.

Thanks for any feedback.

2020-08-04 Thread Andrew Welham 
As my systems are pinned not to accept isc-dhcp-server upgrades, as I run the 
18.04 version as it works. I extracted the dhcpd file from your packages and 
dropped it in place.

2020-08-03 Thread Jorge Niedbalski 
** Follow up from my previous comment, I've built a PPA with a fix similar to 
the one
pointed in 430065.

https://launchpad.net/~niedbalski/+archive/ubuntu/fix-1872118

* I'd appreciate if anyone can test that PPA with focal and report back if the
problem keeps reproducible with that version.

In case it does, please upload the crash file / coredump and the configuration
file used.

Thank you.

The code is crashing on this assertion: 
https://gitlab.isc.org/isc-projects/bind9/-/blob/v9_11_3/lib/isc/unix/socket.c#L3364
This was already reported and marked as fixed in debian (?) via [0]

""Now if a wakeup event occurres the socket would be dispatched for
processing regardless which kind of event (timer?) triggered the wakeup.
At least I did not find any sanity checks in process_fds() except
SOCK_DEAD(sock).

This leads to the following situation: The sock is not dead yet but it
is still pending when it is dispatched again.

I would now check sock->pending_send before calling dispatch_send().This
 would at least prevent the assertion failure - well knowing that the
situation described above ( not dead but still pending and alerting ) is
not a very pleasant one - until someone comes up with a better solution.
"""

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=430065#20

** Follow up questions:

0) The reproducer doesn't seems consistent and seems to be related to a race
condition associated with a internal timer/futex.
1) Can anyone confirm that a pristine upstream 4.4.1 doesn't reproduces the 
issue?

[Touch-packages] [Bug 1872118] Re: DHCP Cluster crashes after a few hours

2020-08-03 Thread Jorge Niedbalski 
Hello,

I am trying to setup a reproducer for the mentioned issue. I have 2
machines acting as peers with the following versions:


# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:Ubuntu 20.04.1 LTS
Release:20.04
Codename:   focal

# dpkg -l |grep -i isc-dh
ii  isc-dhcp-client4.4.1-2.1ubuntu5  amd64  
  DHCP client for automatically obtaining an IP address
ii  isc-dhcp-common4.4.1-2.1ubuntu5  amd64  
  common manpages relevant to all of the isc-dhcp packages
ii  isc-dhcp-server4.4.1-2.1ubuntu5  amd64  
  ISC DHCP server for automatic IP address assignment

Primary configuration:  https://pastebin.ubuntu.com/p/XYj648MghK/
Secondary configuration: https://pastebin.ubuntu.com/p/PYkcshZCWK/

# dhcpd -f -d -4 -cf /etc/dhcp/dhcpd.conf --no-pid ens4

So far (after 1.5h) no crash has been reported in any of the servers. 

Questions:

1) Anything missed from the provided configuration?
2) Is this load or concurrency related? meaning a specific amount of leases 
needs to be allocated for this crash to happen? 

I will take a look to an existing crash/coredump.

[Touch-packages] [Bug 1872118] Re: DHCP Cluster crashes after a few hours

2020-07-29 Thread Tomek Mrugalski 
I don't have specific recommendation on this.

The best course of action would be to find a new maintainer that would
update the packages to 4.4.2. The upstream (ISC) does very infrequent
releases. We had 4.4.2 coming out in Jan 2020. We don't know when the
next one (4.4.3) will come out, but we're no longer actively developing
it. We're fixing serious bugs reported by customers (and addressing
security issues if found), so the future releases are driven by that.

My point here is that this isn't that much work to do. Perhaps existing
maintainers could be convinced to do the package updates?

Also, the alternative - ISC Kea - is much superior in many regards. It's
modern, can (but doesn't have to) use MySQL, Postgres and other
databases, has much better performance, is extensible with hooks, much
cleaner configuration using JSON, ability to alter almost every aspect
of its configuration during runtime, the dev version already support
multi-threading etc. This is the ultimate solution to that problem:
migrate to Kea and stop using isc-dhcp altogether.

Finally, ISC provides packages for Kea for many systems, including
Ubuntu. We can work with package maintainers if there are specific
patches that are needed. We don't and we don't be able to do that for
isc-dhcp.

2020-07-24 Thread Andrew Welham 
Tomek, Please remember I tried the version 4.4.2 as suggested and as you
say Ubuntu used 4.4.1, so it could be something to do with the 4.4.1
release or the ubuntu changes. Either way it looks like its not going to
be fixed. Given this how do you apply to have a ISC-DHCP_Server removed
form the Ubuntu bundle for no maintenance.

tried it on a single server in the cluster and it looks like it better,
i.e it actually launches, however there is no -user or -group options,
with different directories and it must be started as root (with no
change of id_  to start, so not secure. I guess thee other changes are
added by ubuntu

[Touch-packages] [Bug 1872118] Re: DHCP Cluster crashes after a few hours

2020-07-15 Thread Tomek Mrugalski 
Can someone affected by this bug compile 4.4.2 and see if this problem
persists? You can get the latest sources from here:
https://ftp.isc.org/isc/dhcp/4.4.2/ Compilation is trivial (untar,
./configure && make). The failover is enabled by default, so no need for
extra switches to configure.

If it does crash, please report it upstream here: https://gitlab.isc.org
/isc-projects/dhcp/-/issues

Ubuntu 20.04 has packages for 4.4.1 (released Feb 2018). The latest
released from ISC (upstream) is 4.4.2, which went out on Jan 2020.

2020-06-20 Thread Andrew Welham 
Looking at the history around isc-dhcp, it appears if i read it properly that 
isc-dhcp sever for Ubuntu has been abandoned.
If this is the case should it even be in the focal build

[Touch-packages] [Bug 1872118] Re: DHCP Cluster crashes after a few hours

2020-06-14 Thread Peter A. Bigot 
I just moved primary dns and dhcp from 16.04.6 LTS to 20.04 LTS and also
observe this behavior.

Primary is isc-dhcp-server 4.4.1-2.1ubuntu5 amd64.  Crashes regularly.

Secondary is isc-dhcp-server 4.3.5-3+deb9 armhf which runs fine.

[Touch-packages] [Bug 1872118] Re: DHCP Cluster crashes after a few hours

2020-06-08 Thread Andrew Welham 
Thats what I did, but had a couple of outages, I had a choice of extending the 
lease time or downgrade. I did also try to disable apparmor, and dhcp gave an 
error (can't remember what though) and crashed I guess AppArmor just detected 
this and killed the process. So far about a week in ad every thing looks good.
The other option i guess (until they fix this) is to build the latest release 
from source. I did not do this due to no automatic patching

[Touch-packages] [Bug 1872118] Re: DHCP Cluster crashes after a few hours

2020-06-08 Thread Joakim Soendojo 
I do have this problem running Ubuntu 20.04.
Have been fiddling around with config, starting and stopping, apparmor and what 
not.
Currently running it in single node with services stopped on the backup.

Not very keen on downgrading but might have to go that path or migrate
to KEA.

A very big thanks for the downgrade fix Andrew.

[Touch-packages] [Bug 1872118] Re: DHCP Cluster crashes after a few hours

2020-06-05 Thread Andrew Welham 
No response, I actually wondering if I logged the bug in the wrong
place. Anyone building a cluster of DHCP servers on Ubuntu 20.04 should
run into this. The above or no one is using Ubuntu for DHCP clusters ?

2020-05-30 Thread Andrew Welham 
MM , Thanks I install the isc-dhcp-server from the Bionic-Security repository, 
and it appears to work.
For anyone else here is how to install an older version of the server,and then 
block updates to the focal version

PLEASE USE AT YOUR OWN RISK

#Backup your old config
sudo mkdir /etc/dhcp.20.04
sudo cp -r /etc/dhcp /etc/dhcp.20.04

#Remove your old isc-dhcp server
sudo apt remove isc-dhcp-server

#Add the old Bionic repository
add-apt-repository 'deb http://security.ubuntu.com/ubuntu bionic-security main'
sudo apt update

#Install isc-dhcp-server from the bionic-security repository
sudo apt-get install -t bionic-security/main isc-dhcp-server
sudo systemctl restart isc-dhcp-server


#Block upgrades of the package from the Focal Repository
edit /etc/apt/preferences.d/repo and add the following lines


Package: isc-dhcp-server
Pin: release a=bionic-security
Pin-Priority: 900
