udhcpd crashes with 'Illegal instruction'

[Marco Davids]

Binary package hint: busybox

package: udhcpd 1:1.15.3-1ubuntu5
OS: Maverick 10.10 (server edition)

When trying to run udhcp, it crashes with an SIGILL while reading the config file. Doing the same with an entire empty config-file will work, but as soon as saomething is entered, even if it is only a # character, the application crashes.

Here are the last few lines of the strace output of 'strace -f udhcpd':

open("/etc/udhcpd.conf", O_RDONLY|O_LARGEFILE) = 3
fstat64(3, {st_mode=S_IFREG|0644, st_size=3158, ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb781f000
read(3, "# Sample udhcpd configuration fi"..., 4096) = 3158
--- SIGILL (Illegal instruction) @ 0 (0) ---
Process 17853 detached

btw, kernel version is: Linux xs 2.6.35-24-generic-pae #42-Ubuntu SMP Thu Dec 2 03:21:31 UTC 2010 i686 GNU/Linux

I can confirm this bug.

Looks to me like it only reads the first 32-bytes of the config, then dies.

Running the same udhcpd package as Marco, but the kernel in my case is 2.6.35-22-generic-pae #35-Ubuntu SMP Sat Oct 16 22:16:51 UTC 2010 i686 GNU/Linux

Running Lucid's udhcpd_0.9.8cvs20050303-3_i386.deb works as a temorary workaround.
