[Bug 235309] [NEW] dhcp3-server crashes with bootp clients

[alkisg]

Public bug reported:

Ubundu hardy, 3.0.6.dfsg-1ubuntu9  
To reproduce the crash:

(1) In dhcp3.conf, put a dynamic-bootp range, like:
range dynamic-bootp 192.168.0.201 192.168.0.220;
(2) In /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default, add ip=bootc, like:
DEFAULT vmlinuz ro initrd=initrd.img ip=bootp
(3) sudo /etc/init.d/dhcp3-server restart

Then boot up a pxe client. Dhcp3-server should halt with an entry in
syslog saying:

kernel: [ 5600.238937] dhcpd3[12225]: segfault at 00000004 eip 0804ed83
esp bfd34e80 error 4


My dhcpd.conf file, stripped down as it was used to locate the problem:

subnet 192.168.0.0 netmask 255.255.255.0 {
	range dynamic-bootp 192.168.0.201 192.168.0.220;
	option subnet-mask 255.255.255.0;
	option root-path "/opt/ltsp/i386";
	if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient" {
		filename "/ltsp/i386/pxelinux.0";
	} else {
		filename "/ltsp/i386/nbi.img";
	}
}
