Package: dhcp-helper
Version: 1.0-1
Severity: normal
Hi,
dhcp-helper does not work with interfaces that have a label (created
with "ip addr add dev int103 10.1.103.254/24 brd + label
int103:67fe8). It simply doesn't forward an incoming request.
strace excerpt:
recvmsg(3, {msg_name(16)={sa_family=AF_INET, sin_port=htons(68),
sin_addr=inet_addr("0.0.0.0")},
msg_iov(1)=[{"\1\1\6\0002\307\270S\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\37\26&"...,
548}], msg_controllen=24, {cmsg_len=24, cmsg_level=SOL_IP, cmsg_type=, ...},
msg_flags=0}, MSG_PEEK) = 300
recvmsg(3, {msg_name(16)={sa_family=AF_INET, sin_port=htons(68),
sin_addr=inet_addr("0.0.0.0")},
msg_iov(1)=[{"\1\1\6\0002\307\270S\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\37\26&"...,
548}], msg_controllen=24, {cmsg_len=24, cmsg_level=SOL_IP, cmsg_type=, ...},
msg_flags=0}, 0) = 300
ioctl(3, SIOCGIFNAME, {ifr_index=14, ifr_name="int103"}) = 0
ioctl(3, SIOCGIFADDR, {ifr_name="int103", ???}) = -1 EADDRNOTAVAIL (Cannot
assign requested address)
recvmsg(3, {msg_name(16)={sa_family=AF_INET, sin_port=htons(68),
sin_addr=inet_addr("0.0.0.0")},

Calling dhcp-helper with -i int103:67fe8 instead if -i int103 doesn't
hellp. Removing the label from the interface (ip addr del dev int103
10.1.103.254/24; ip addr add dev int103 10.1.103.254/24) does.
dhcp-helper should properly handle interfaces with labels.
