[PATCH v5 0/3] support dump ssh via link local ipv6 address

[Ziyue Yang]

When dumping to ssh via local ipv6 address, the ssh parameter
in kdump.conf is supposed to have the form like

ssh user@fe80::cc1:8bff:fe90:b95f%eth0

where "%eth0" is an existing network interface supporting ipv6.

However, there are 3 problems in enabling ipv6:

1) The get_remote_host function in kdump-lib.sh currently
doesn't remove the network interface in the ipv6 address,
causing the ip command in kdump_install_net function to fail,
leading to a "Bad kdump location" message.

2) The kdump_setup_ifname function in dracut-module-setup.sh
would add 'kdump-' prefix to network interfaces with name like
'eth*', causing ssh target specified in kdump.conf invalid
while dumping process.

3) ssh target with 'kdump-' prefixed interface name is not
in known_hosts while dumping, leading to ssh connection failure.

This patch series handles the problems above.

Ziyue Yang (3):
  kdump-lib.sh: support link local ipv6 address with interface name
  dracut-module-setup.sh: add 'kdump-' prefix in kdump.conf for link
    local ipv6
  dracut-kdump.sh: support 'kdump-' prefixed interfaces for link local
    ipv6
