[Patch v5] Add static route into cmdline if target address is not local

If one target address is not local and its route is different than default gateway, the specific route to this target address need be added. E.g, target is 192.168.200.222. sh> ip route show default via 192.168.122.1 dev eth0 proto static metric 1024 192.168.200.0/24 via 192.168.100.222 dev ens10 proto static metric 1 In this patch, get the route to the specific target address and store it as cmdline, here is /etc/cmdline.d/45-route-static.conf. And the route options are separated by semicolon like below. Then the stored route can be parsed when kdump kernel boot up. 192.168.200.0/24:192.168.100.222:ens10 Signed-off-by: Baoquan He <bhe(a)redhat.com&gt; --- dracut-module-setup.sh | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/dracut-module-setup.sh b/dracut-module-setup.sh index 5ab2997..fefbe4b 100755 --- a/dracut-module-setup.sh +++ b/dracut-module-setup.sh @@ -79,6 +79,11 @@ kdump_static_ip() { _gateway=$(ip route list dev $_netdev | awk '/^default /{print $3}') echo -n "${_srcaddr}::${_gateway}:${_netmask}::" fi + + /sbin/ip route show | grep -v default | grep "^[[:digit:]].*via.* $_netdev " |\ + while read line; do + echo $line | awk '{printf("rd.route=%s:%s:%s\n", $1, $3, $5)}' + done >> ${initdir}/etc/cmdline.d/45route-static.conf } kdump_get_mac_addr() { -- 1.8.5.3
