mknb writes the compressed genesis filesystem by streaming cpio output
straight onto the final path in $tftpdir/xcat (genesis.fs.$arch.lzma or .gz).
When two mknb/nodeset runs target a shared $tftpdir at once, one run reads or
overwrites the other's half-written image, producing a corrupt genesis.fs and
failed netboots.
Write each image to a uniquely-suffixed temporary file
(xCAT::Utils::genpassword(24)) and File::Copy::move() it into place. move()
within the same directory is a rename, so the final path only ever appears
complete. Both modules are already imported by mknb.pm.
Recovered from the unmerged lenovobuild branch (originals c651e7b8 and its
fix da0723f2, which switched the suffix to genpassword after the first
attempt only produced a single character). master lacks the branch's xz
path, so only the lzma and gzip paths are adjusted here.

When nodehm.conserver is a hostname, rcons compared that name directly against
the management node's local IP addresses, so the "conserver is this host"
check never matched and rcons connected via `-s` (a remote confluent session)
even when the conserver was the local host. Resolve the name to an address
with getent first so the comparison works.

tcons opens an rcons console per node in a tiled tmux session. On tmux 3.x
(shipped by all currently supported platforms) it no longer works:
* The session was named "tcons.$$". Modern tmux treats "." as the
session:window.pane target separator, so "tmux attach -t tcons.$$" is
parsed as session "tcons", pane "$$" and fails with "can't find
session"/"can't find pane" -- tcons cannot attach to the session it
just created. Rename it to "tcons_$$".
* The per-node "tmux select-pane", "tmux split" and "tmux select-layout"
commands had no target. When tcons is run from inside an existing tmux
session (the common case) they act on the caller's current session
instead of the detached tcons session, splitting the operator's own
window. Target every command explicitly at the tcons session.
* Move the pane-border-status option inside the loop so the console title
is set on each pane as it is created.
Validated on tmux next-3.4: the reworked script builds a 3-pane tiled
session with no errors, whereas the previous version's dotted session name
is unaddressable ("can't find pane").

(cherry picked from commit dda7605028)
replaycons chose the confluent console log directory
(/var/log/confluent/consoles) whenever the confetty binary happened to be
present. On a host that has confluent installed but runs conserver as the
active console service, that directory is empty and replaycons could not find
the log. Gate on the site table's consoleservice attribute instead -- the
same setting rcons uses -- so replaycons reads /var/log/confluent/consoles
only when confluent is actually the configured console service.

(cherry picked from commit 21da014ed7)
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.

(cherry picked from commit 60bd6e7cd9)
The DNS-managed-networks check used my_ip_facing($net->{net}), which only
returns local addresses on the interface directly facing that network. A
nameserver that is a local address reachable via a different (routed)
interface was therefore treated as external, and the network was wrongly
dropped from ddns management.
Use thishostisnot(), which recognizes any local address regardless of the
interface, and keep the existing <xcatmaster> and site-nameserver special
cases.
Recovered from the unmerged lenovobuild branch (original 3c343f83), adapted
to preserve those special cases: lab validation showed the original replaced
them wholesale, which would exclude any network whose nameserver is the
literal <xcatmaster> token (thishostisnot('<xcatmaster>') is true).

For each secondary NIC in NICSTOBRINGUP, doxcat backgrounds a loop that polls
`ethtool $nic` until the link reports "detected: yes" before running dhclient.
A NIC that is never connected keeps that loop (and its `sleep 5`) running for
the life of the genesis environment, leaking background shells and needlessly
churning.
Add a second exit condition so each loop also stops once /tmp/netinitted
exists, and touch that file once the boot NIC has completed network init. A
link that never appears no longer waits indefinitely.

The genesis boot script sleeps 20 seconds unconditionally with the comment
"wait for NIC initialization", but that wait exists solely for System P LE
(ppc64) hardware discovery -- the surrounding section is explicitly ppc64
only. Every x86_64 and aarch64 node therefore pays a needless 20s delay on
each genesis boot.
Move the sleep inside the `[[ ${ARCH} =~ ppc64 ]]` block so only ppc64 waits.
Applied to the base script and both dracut_105 (el, ubuntu) variants.

(cherry picked from commit 32149f10f4)
ddns.pm's DNS-update send has a 3-try retry loop, but it only retried on
NOTAUTH and -- on the final attempt -- the `next` fell out of the loop without
reporting failure. makedns then printed "Completed updating DNS records." and
"DNS setup is completed" even when the update was never accepted.
Two problems this causes:
- SERVFAIL was never retried. named routinely replies SERVFAIL transiently
right after a zone (re)load, before the zone is ready to accept dynamic
updates; the update succeeds a second or two later. This reliably breaks real
flat-cluster provisioning on el9/el10, where the test case's makedns -n runs
right after named reloads the zone with the new compute node.
- A persistent NOTAUTH/SERVFAIL (retries exhausted) was silently swallowed and
reported as success, so a genuinely failed DNS update looked like it worked.
Extract the batch send into send_ddns_update(), which retries NOTAUTH and
SERVFAIL (pausing on SERVFAIL), returns 0 only on NOERROR, and otherwise emits
the error and returns 1. Both batch-send sites now `return 1 if
send_ddns_update(...)`, so a real failure aborts add_or_delete_records instead
of falsely reporting success.

go-xcat's install list still named yaboot-xcat, which was obsoleted in the
xcat-dep 2.18 rebuild and is no longer published. It also lists the cross-arch
ppc64 genesis packages, which the arch-split 2.18 dep repo no longer places in
the x86_64 view an x86 management node reads. Because EL dnf is strict by
default, any one of these unresolvable names aborts the entire `dnf install`
transaction, so `go-xcat install` fails outright on EL9/EL10 even though every
package the node actually needs is available.
Drop yaboot-xcat from the install list (kept in the uninstall list so existing
installs are still cleaned up) and pass `dnf --setopt=strict=0` so a package
missing from the enabled repository is warned and skipped instead of failing
the whole install. The existing post-install smoke test still catches a
genuinely broken install.

2.18.1 was already published to the EL yum repos on 2026-07-10
(xCAT-2.18.1-snap202607100105, from master commit f6deff08b, now
tagged 2.18.1 on this branch). A released version number is
immutable, so the next 2.18.x release from this branch is 2.18.2.
On the ubuntu-24.04 runner, dpkg-buildpackage aborted every xcat-core
package with 'Unmet build dependencies: build-essential:native', so zero
debs were produced, reprepro created no dists/noble, and 'apt-get update'
against the local file: repo failed with 'dists/noble/.../Packages File
not found' -> install_xcat failed. Add build-essential to the workflow
dependency install so the local package repo is actually built.
(cherry picked from commit f9717ea8da)
The xcat-dep APT repo now publishes only the noble (24.04) codename at
.../apt/latest/xcat-dep; the bionic/devel dist no longer exists, so
install_xcat failed on apt-get update/install. Run the workflow on
ubuntu-24.04 and point the apt source at latest/xcat-dep noble main.
Drop the apt-key step: apt-key is removed on Ubuntu 24.04 and the legacy
apt.key is gone from the xcat-dep dir; the repo already installs via
allow-insecure-repositories/allow-unauthenticated.

cons/kvm drives the KVM guest serial console through a shared tmux session on
the hypervisor (tmux, unlike screen, is present on every libvirt host we target
incl. ppc64le hosts that ship no screen). The KVM host package lists were never
updated for that switch, so an xCAT-provisioned KVM host got 'screen' (now
unused) -- or nothing -- where tmux is required, leaving rcons broken.
Ship tmux in the KVM host pkglists:
- install/rh, install/ubuntu: screen -> tmux / add tmux.
- netboot/{alma,centos,rocky}: were symlinks to the RHEL 5.4 list; make them
real lists with tmux (the rhel5/6/7 lists keep screen).
- install/suse: add a KVM host list (SUSE had none) carrying tmux.
screen stays where it is still used: the Xen console, and the EOL rhel5/6/7 and
centos6/7 lists.

Requiring xCAT-genesis-base >= 2:%{version} coupled the flat xcat-core to a
matching genesis-base on every marketing-version bump: a 2.18.1 core refused
to install against the deployed 2.18.0 genesis-base. genesis-base changes
rarely and lives in the separate per-EL xcat-dep repo, so floor the requirement
at the fixed 2.18.0 baseline instead. Core version bumps no longer force a
genesis-base re-publish.
