Recently, dracut-network drops depedency on dhcp-client which requires
ipcalc. Thus the dependency chain
"kexec-tools -> dracut-network -> dhcp-client -> ipcalc"
is broken. When NIC is configured to a static IP, kexec-tools depended
on "ipcalc -m" to get netmask. This commit implements the shell
equivalent of "ipcalc -m".
The following test code shows cal_netmask_by_prefix is consistent with
"ipcalc -m",
#!/bin/bash
. dracut-module-setup.sh
for i in {0..128}; do
mask_expected=$(ipcalc -m fe::/$i| cut -d"=" -f2)
mask_actual=$(cal_netmask_by_prefix $i "-6")
if [[ "$mask_expected" != "$mask_actual" ]]; then
echo "prefix="$i, "expected="$mask_expected, "acutal="$mask_actual
exit
fi
done
echo "IPv6 tests passed"
for i in {0..32}; do
mask_expected=$(ipcalc -m 8.8.8.8/$i| cut -d"=" -f2)
mask_actual=$(cal_netmask_by_prefix $i "")
if [[ "$mask_expected" != "$mask_actual" ]]; then
echo "prefix="$i, "expected="$mask_expected, "acutal="$mask_actual
exit
fi
done
echo "IPv4 tests passed"
i=-2
res=$(cal_netmask_by_prefix "$i" "")
if [[ $? -ne 1 ]]; then
echo "cal_netmask_by_prefix should exit when prefix<0"
exit
fi
res=$(cal_netmask_by_prefix "$i" "")
if [[ $? -ne 1 ]]; then
echo "cal_netmask_by_prefix should exit when prefix<0"
exit
fi
i=33
$(cal_netmask_by_prefix $i "")
if [[ $? -ne 1 ]]; then
echo "cal_netmask_by_prefix should exit when prefix>32 for IPv4"
exit
fi
i=129
$(cal_netmask_by_prefix $i "-6")
if [[ $? -ne 1 ]]; then
echo "cal_netmask_by_prefix should exit when prefix>128 for IPv4"
exit
fi
echo "Bad prefixes tests passed"
echo "All tests passed"
