dhcp fails to hand out leases and complains with errors on boot
Last modified: 2007-11-30 17:10:57 EST
Description of problem: After updating to last nights new DHCP (-16), I'm now seeing these messages logged on boot: Jan 6 00:58:33 tornado dhcpd: Lease with bogus binding state: 257 Jan 6 00:58:33 tornado last message repeated 4 times and while running: Jan 6 00:58:50 tornado dhcpd: DHCPREQUEST for 192.168.0.13 from 00:90:27:23:ee:12 via eth0: unknown lease 192.168.0.13. Jan 6 01:01:53 tornado last message repeated 3 times Jan 6 01:02:04 tornado last message repeated 2 times Jan 6 01:02:23 tornado dhcpd: DHCPDISCOVER from 00:06:5b:d7:03:d7 via eth0: network 192.168.0.0/24: no free leases Jan 6 01:03:28 tornado last message repeated 4 times This is an error. There are plenty of free leases... Version-Release number of selected component (if applicable): 3.0.1-16 How reproducible: very. The problem persists over removing the dhcp.leases file and restarting. I downgraded to 3.0.1-11 and everything worked OK again.
Did you install the binary FC4/rawhide dhcp-3.0.1-16 package on an FC3 system ? If so, this is not likely to work, as the gcc and glibc version dhcp was built with on FC4 are not in FC3 - doing a : # rpmbuild --rebuild dhcp-3.0.1-16.src.rpm and then installing the packages produced in /usr/src/redhat/RPMS/$arch should work, but you have to change the compiler to gcc33 - (see bug #139299) gcc or gcc4 on FC3 won't work, as the 'binding_state_t' variables are not made into byte values as in FC4 / gcc33 - it sounds like you already built with gcc/gcc4 and the binding_state_t variables get an invalid byte value of 257 . You can download dhcp-3.0.1-16 built for i386/FC3 (and the dhcp-3.0.1-16.src.rpm that uses gcc33) from: http://people.redhat.com/~jvdias/dhcp/FC3 Please try this version and let me know if you still have a problem. I've tested it on i386/FC3 with no problems. I'll be pushing this into FC3 updates, but this takes some time. By the way, the server lease database is: /var/lib/dhcp/dhcpd.leases ^ not dhcp.leases did you try removing the real leases file and restarting ?
Yes, this is on a system running latest devel/rawhide. I made a typo with dhcpd.leases, I deleted both files after stopping dhcpd. I only reverted to -11 from FC3 as this was the only one I could get my hands on other than the latest version ;-)
What architecture is this system ? not i386 ? There could be a problem with the GCC on our build servers. The message : Jan 6 00:58:33 tornado dhcpd: Lease with bogus binding state: 257 indicates that the binding_state_t variables have a size > 1 (a known gcc issue).
It's a P4/i386...
This problem is caused by gcc bug #144358 . Until the default 'gcc' compiler is fixed, DHCP must be compiled with gcc33 from the compat-gcc-8-3.3.4.2 package. I've submitted dhcp-3.0.1-17 to FC4/rawhide that is compiled with gcc33, which should be available in the next rawhide release. *** This bug has been marked as a duplicate of 144358 ***
