The packet test runs dhcpd and kea-dhcp4 in a network namespace with the
rules that BootPolicy renders, and sends relayed DHCPDISCOVER packets
from a second namespace. It checks the boot file of firmware PXE, xNBA
and iPXE clients, with each iPXE feature present or missing, for an xnba
node and an ipxe node that install, for both methods with a SAN disk,
and for an unknown node. On ISC it also covers an iSCSI node of each
method in the boot state, and repeats the node rows after a restart,
when dhcpd reads the host statements back from dhcpd.leases. On Kea it
repeats the rows of the ipxe nodes with a configuration that makedhcp
upgraded, which keeps the xNBA global classes of the older makedhcp -n.
It also checks that the UEFI clients of an xnba node get xNBA when the
server lacks the xNBA UEFI file.
The Kea validation test checks the x86 classes of xnba and ipxe nodes
with kea-dhcp4 -t. XCAT::Test::DHCP builds the packets, and the
integration case expects seven files.
dhcpd keeps the host statements that makedhcp gives it through OMAPI in
dhcpd.leases, where it saves them without parentheses, and reads them
back when it restarts.
The lease test stores the statements of netboot=ipxe nodes through OMAPI
in a private network namespace, checks the saved leases with dhcpd -t,
and restarts dhcpd with them. The configuration test checks the iPXE
feature declarations of the ISC header with dhcpd -t.
start_daemon can now keep the identity of the caller, and the
integration case expects six files.
The helpers that start, wait for and stop a DHCP daemon lived in the
Kea smoke test. The ISC lease test and the packet test need them too.
They move to XCAT::Test::DHCP in integration/lib, which the xCAT-test
packages install with the tests. The smoke test loads them from there
and behaves as before.
