makedhcp on a noderange sends the request to every service node running a dhcp
server, whether or not it serves any of the named nodes. On a cluster with many
service nodes each one does the work and reports on nodes that are not its
responsibility, for example warning that a node it does not serve has no mac
address.
Map the named nodes to their service nodes and skip the rest. Regenerating the
networks with -n still reaches every dhcp server, since a dynamic range is not
tied to a node, and if none of the named nodes can be mapped the request goes to
all of them as before rather than risk leaving one out.
The node to service node mapping reuses getSNformattedhash, which the
disjointdhcps path in this same function already uses.

makedhcp using the Kea backend fails for any node whose mac table entry
uses the *NOIP* sentinel to mark a secondary NIC that has no IP address
(e.g. "mac1|mac2!*NOIP*|mac3!*NOIP*"). kea_node_reservations() and
kea_node_reservations6() split each NIC's hostname and pass it straight
to getipaddr(), so the literal string "*NOIP*" is treated as a host to
resolve. It cannot resolve, and the reservation is reported as unresolved
-- which aborts the whole makedhcp run, leaving the node with no Kea
reservation at all and therefore no DHCP lease.
This breaks provisioning on distros that use the Kea backend (e.g. EL10,
which has no ISC dhcp-server): the node never gets an address and is
unreachable, while the ISC backend has always handled *NOIP* and is
unaffected.
Skip *NOIP* NICs in both the DHCPv4 and DHCPv6 reservation builders, the
same way the ISC path does -- there is no address to reserve for them.

Boot URLs handed to nodes always carried an explicit :80 even when the HTTP
server listens on the default port. grub2.pm already omits the port when it is
80; make the xNBA, genesis and DHCP boot URLs consistent with it.
$portsuffix is empty when site.httpport is unset or 80 and ":<port>" otherwise,
so a non-default port is unchanged. Covers the ISC and Kea paths in dhcp.pm,
xnba.pm, mknb.pm, and the Kea xNBA client classes in BootPolicy.pm.
dhcp_boot_policy.t and mknb_xcatd_address.t follow the new URLs and gain cases
for a non-default and an unset port. The floating-address guard in
mknb_xcatd_address.t also drops :80 so that it keeps matching.

Modern x86-64 UEFI firmware (including OVMF and recent iPXE) reports DHCP
client architecture 00:07, but the xNBA network-boot conditionals only matched
00:09. A UEFI node would load xnba.efi, re-request with user-class xNBA and
arch 00:07, fail to match, and be handed xnba.efi again -- an endless boot
loop. Accept 00:07 alongside 00:09 in the xNBA UEFI branches of both the
network-level (addnet) and node-level (addnode) dhcpd statements.
Validated on an OVMF UEFI client: it progresses from xnba.efi to the .uefi
genesis config and boots, instead of looping on xnba.efi.

getzonesfornet() derives the number of reverse-zone nibbles as
$nibbs = $maskbits / 4, then decrements it once per hex nibble of the network
prefix. For a sub-nibble (not 4-bit-aligned) IPv6 mask $nibbs can go negative
before the padding loop, and `while ($nibbs)` then never terminates: it keeps
decrementing past zero while appending "0." to $rev, spinning forever and
growing the string until the process is killed.
Make the padding loop `while ($nibbs > 0)` so it can never run away, and
return early only when $nibbs is genuinely negative. $nibbs == 0 is the normal
nibble-aligned case (e.g. a /64) and must still emit its reverse zone.
Recovered from the unmerged lenovobuild branch (original 0e070cd2). The
original guarded with `$nibbs < 1`, which also dropped the valid $nibbs == 0
case and left standard /64 subnets with no reverse zone; corrected to
`$nibbs < 0` after lab validation on a real provisioning cluster.

The activenics{"!remote!"} hash key is checked at line 1940 but never
set by any code path — neither the dhcpinterfaces parsing nor the
querynics discovery populates it. This causes the guard to always
evaluate true, hitting next and silently skipping every !remote!
network when dhcpinterfaces is defined in the site table or on a
service node.
Remove the dead check so remote networks are processed correctly.
The inner activenics{$netif} check (which uses the actual interface
name after stripping the !remote! prefix) is the correct guard and
is preserved.

Add a shared OMAPI policy helper for ISC DHCP and DDNS so administrators can select the key name, signing algorithm, and omshell path from the site table while preserving the existing xcat_key hmac-md5 default.
Keep local ISC updates from hanging indefinitely when omshell does not exit, and use a static host-declaration fallback for local Ubuntu ISC releases where omshell is unstable for xCAT host updates.

Previously, makedhcp warned but still created host entries without
a static IP reservation when a node's address fell inside the
dynamic range. The node would silently get a random IP from the
pool instead of its configured address.
Now errors and skips the node on all four DHCP paths (ISC v4/v6,
Kea v4/v6) with a clear message telling the admin to move the IP
outside the range or adjust the dynamic range.
This makes ISC DHCP and Kea behavior consistent and aligns with
xCAT's design: the dynamic range is for hardware discovery,
known nodes should have static IPs outside it.
