Title:
  isc-dhcp-server fails to start on second & further attempts with
  'Can't open /var/lib/dhcp/dhcpd.leases for append'

Status in isc-dhcp package in Ubuntu:
  Fix Released

Bug description:
  During the first start of isc-dhcp-server (using the systemd service
  unit), a blank dhcpd.leases file is created (presumably owned by
  root:root).  dhcpd starts successfully (and then exits due to no
  subnet definitions, that's expected).

  Attempting to start the service again fails with 'Can't open
  /var/lib/dhcp/dhcpd.leases for append' (the dhcpd.leases file
  ownership is now dhcpd.dhcpd), and apparmor logs a denial of the
  dac_override capability.

  Removing the leases file repeats this process (first start works as
  expected, future ones do not).

2017-01-09 Thread Rolly Ng
Issue still exists with fresh installation of 16.04 server.

rolly@head:~$ apt-show-versions | grep isc-dhcp-server
isc-dhcp-server:amd64/xenial-updates 4.3.3-5ubuntu12.6 uptodate

it works with the solution:
sudo ln -s /etc/apparmor.d/usr.sbin.dhcpd /etc/apparmor.d/disable/
sudo apparmor_parser -R /etc/apparmor.d/usr.sbin.dhcpd

I am running dhcpd on infiniband, ipoib on ib0, here is the working output:

[Touch-packages] [Bug 1543794] Re: isc-dhcp-server fails to start on second & further attempts with 'Can't open /var/lib/dhcp/dhcpd.leases for append'

2016-08-12 Thread Steve Langasek
The output in comment #8 shows that this system is running upstart
despite being 16.04.  Upstart is not supported as init on 16.04 except
during the upgrade.  This bug appears to have been fixed for the systemd
unit, but not for the upstart job.  A simple reboot to systemd should
suffice to fix the problem on 16.04.

This is the workaround that I used after upgrading to 16.04:

sudo ln -s /etc/apparmor.d/usr.sbin.dhcpd /etc/apparmor.d/disable/
sudo apparmor_parser -R /etc/apparmor.d/usr.sbin.dhcpd

How to reproduce (using /etc/dhcp/dhcpd.conf installed from the package

(LP: #1543794):
- /var/lib/dhcp is root:dhcpd and 775
- /var/lib/dhcp/dhcpd{,6}.leases is root:dhcpd and 664
- don't chown /run/dhcp-server to dhcpd:dhcpd since the pid file is now
  created as root:root and the pid file was not being created before. If
  this needs to be reintroduced in the future, use root:dhcpd and 775,
  like with the leases file.

  isc-dhcp-server fails to start on second & further attempts with

Status in isc-dhcp package in Ubuntu:
  Fix Released

Bug description:
  During the first start of isc-dhcp-server (using the systemd service
  unit), a blank dhcpd.leases file is created (presumably owned by
  root:root).  dhcpd starts successfully (and then exits due to no
  subnet definitions, that's expected).

  Attempting to start the service again fails with 'Can't open
  /var/lib/dhcp/dhcpd.leases for append' (the dhcpd.leases file
  ownership is now dhcpd.dhcpd), and apparmor logs a denial of the
  dac_override capability.

  Removing the leases file repeats this process (first start works as
  expected, future ones do not).

[Touch-packages] [Bug 1543794] Re: isc-dhcp-server fails to start on second & further attempts with 'Can't open /var/lib/dhcp/dhcpd.leases for append'

2016-02-27 Thread Doug Smythies
Yes, isc-dhcp - 4.3.3-5ubuntu8 fixes the issue with the dhclient stuff
that caused this:

Feb 26 14:05:21 DOUG-64 kernel: [   17.518717] audit: type=1400
audit(1456524321.220:10): apparmor="DENIED" operation="open"
profile="/sbin/dhclient" name="/etc/ssl/openssl.cnf" pid=483
comm="dhclient" requested_mask="r" denied_mask="r" fsuid=0 ouid=0

However, that is not what this bug report is about. This bug report is
about these ones:

Feb 27 07:53:07 DOUG-64 kernel: [   21.350331] audit: type=1400 
audit(1456588387.171:12): apparmor="ALLOWED" operation="capable" 
profile="/usr/sbin/dhcpd" pid=1248 comm="dhcpd" capability=1  
capname="dac_override"
Feb 27 07:53:07 DOUG-64 kernel: [   21.466959] audit: type=1400 
audit(1456588387.287:13): apparmor="ALLOWED" operation="capable" 
profile="/usr/sbin/dhcpd" pid=1248 comm="dhcpd" capability=3  capname="fowner"

Note: the above are "ALLOWED" because I have it set to complain mode.

which were fixed, but have now returned. 
setting back to confirmed.
