Subject: erroneous static network interface broadcast address
The Debian Installer repeatedly crashes my DSL modem. There have never
been any other problems except with D-I. I think the broadcast address
is the problem. The problem occurs especially when the installer tries
to fetch files from the internet before rebooting. The network is good
after rebooting. I think the netcfg is the problem or else busybox. This
is what I found when checking before rebooting:
========= preboot installation /etc/network/interfaces ==============
============ this was correctly written by the installer ============
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.2.64
netmask 255.255.255.0
network 192.168.2.0
broadcast 192.168.2.255
gateway 192.168.2.1
# dns-* options are implemented by the resolvconf package, if installed
dns-nameservers 192.168.2.1
dns-search localnet
======== preboot installation ifconfig ===============
======== this was not correctly initialized ==========
eth0 Link encap:Ethernet HWaddr 00:11:2F:E0:3A:27
inet addr:192.168.2.64 Bcast:0.0.0.0 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

RX bytes:49876 (48.7 KiB) TX bytes:3281 (3.2 KiB)
Interrupt:17 Memory:fba00000-0
============ the above Bcast:0.0.0.0 is incorrect =========
I found this code in the netcfg/static.c file. The fprintf must be good.
I think the broadcast.s_addr is wrong when initializing interface:
static.c: struct in_addr broadcast = { 0 };
static.c: broadcast.s_addr = (network.s_addr | ~netmask.s_addr);
static.c: fprintf(fp, "\tbroadcast %s\n", inet_ntop (AF_INET, &broadcast, ptr1, sizeof (ptr1)));
............
Thanks for the attention

Changes:
netcfg (1.08) unstable; urgency=low
.
* Joshua Kwan
- Ask for nameserver information if the DHCP server did not provide
any. closes: #281924
- Pass broadcast parameter to ip because it doesn't actually set it.
Generally harmless, but we crash DSL modems now. closes: #295482
- Fix some translation issues with Choices.
* Joey Hess
- If heuristics fail to determine a default interface, use the first
interface as the default.
- Back up netcfg/choose_interface preseeded value, and if the question
is not displayed to the user, restore that value, overriding the
selected default interface. Unless it was preseeded to "auto", then we
use the selected default interface anyway.
- That should make interface preseeding work in all situations.
Closes: #293682
