[Bug 295520] [NEW] dhcp3-server vlan support seems to be broken
Public bug reported: Binary package hint: dhcp3-server Description:Ubuntu 8.10 Release:8.10 dhcp3-server: Installed: 3.1.1-1ubuntu2 Candidate: 3.1.1-1ubuntu2 Version table: *** 3.1.1-1ubuntu2 0 500 http://de.archive.ubuntu.com intrepid/main Packages 100 /var/lib/dpkg/status libpcap-dev: Installed: (none) Candidate: 0.9.8-5 Version table: 0.9.8-5 0 500 http://de.archive.ubuntu.com intrepid/main Packages -- Let's have both an untagged "eth0" and a vlan "vlan2" which uses eth0 as it's raw device. -- Assign 192.168.0.1/24 to eth0 -- and 192.168.3.1724 to vlan2. -- Configure both subnets in dhcpd3.conf When a request on the untagged network comes in, everything is fine: dhcpd receives and answers it on eth0.

With 8.04, this seemingly did NOT happen: The vlan tagged request was only processed on vlan2. Some investigation suggests, however, that this is a problem in dhcpd3 which just didn't always show up in 8.04. There is a change regarding the handling of VLAN packets and packet filters in kernel 2.6.27 which makes sure that vlan tagged packets are always presented to filters on the underlying device (eth0 in this case) with the vlan tag removed from the packet data. Previously (depending on the ethernet driver, from what I could understand) the raw data was also presented, but with the vlan tag still present. Thus, before 2.6.27 and as a side-effect of not expecting the vlan tag, dhcpd's LPF code would filter the vlan tagged packet away as not a valid bootp/dhcp packet, and the dhcpd3 application code was only seeing the packet which was received via the "vlan2" device. Starting with 2.6.27, the LPF code now matches for both the vlan2 received packet, and the eth0 received packet, thus causing above problem. If the analysis is correct, this needs to be fixed upstream in dhcpd's linux interfacing code. ** Affects: dhcp3 (Ubuntu) Importance: Undecided Status: New -- dhcp3-server vlan support seems to be broken https://bugs.launchpad.net/bugs/295520 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
