genpdu read negative-capable sensors from the unsigned value column,
which the MIB leaves undefined for them: a PX4 answers it with 0 for
inlet reactive power and carries the reading in the signed column. Use
SensorSignedMinimum to pick the column, as the MIB specifies. The
unsigned column is still needed for active energy, whose range exceeds
Integer32 and reads 0 in the signed one.
An unreachable PDU or a wrong credential looked like a PDU without
switched outlets, since the switching probe was the first exchange with
the device. Probe pduCount first (implemented by every PDU2 agent,
verified on PX2, PX3 and PX4) and return no session when it fails, so
callers print "Couldn't connect to <pdu>". Warn when pduCount is not 1
rather than refusing: a linked primary still answers for its own
outlets.
Add unit tests for the genpdu sensor, session and inventory paths.

Add a new pdutype (genpdu) for PDUs implementing the Raritan PDU2-MIB.
A single MIB covers the Raritan PX2/PX3/PX4/PXC/SRC/PXO/BCM series, the
Server Technology PRO3X/PRO4X series, the Legrand intelligent PDUs, and
all PDUs following the PDU2-MIB.
Supports rpower (whole-PDU and per-outlet), rinv and rvitals over SNMP
v1, v2c or v3, with credentials read from the pdu table).
Unlike the existing types, sensor units and decimal precision are read
from the MIB per sensor rather than hardcoded, so readings are correct
across models that report differing precision for the same sensor.
Outlet switching capability is probed at connect time, so metered-only
models report a single "unsupported" message instead of a per-outlet error.
rspconfig is not supported for genpdu; PDU linking and BCM2/PMC power
meters are out of scope.
Tested on Raritan PX4-5851-E7V2 (fw 4.2.10.5-50400, switched),
PX3-1901U-N1 and PX3-1901U-N1A6 (fw 4.0.20.5-49038, metered), and
PX2-1901U-N1A6 (fw 4.0.20.5-49038, metered).

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.

The CUDA docs were frozen at CUDA 9.2 / RHEL 7.5 / Ubuntu 14.04 since
2019. Update to cover all currently supported OS and architecture
combinations (EL 7-10, Ubuntu 20.04-24.04, x86_64/ppc64le/sbsa).
Consolidate the version-specific repo and osimage pages into generic
guides that use placeholder variables, reducing 7 files to 2 while
covering more OS versions. Both online (direct NVIDIA repo URL) and
offline (dnf download / apt download mirroring) workflows are
documented.
All NVIDIA repository URLs validated against
developer.download.nvidia.com/compute/cuda/repos/ and confirmed
accessible with valid repodata.
Addresses #7373
The default xCAT Apache configuration shipped with Options Indexes
enabled for the /install and /tftpboot directories. This allowed
unauthenticated users to browse directory listings, disclosing the
full tree of postscripts, boot files, and (in production deployments)
potentially kickstart files with password hashes, custom scripts with
embedded credentials, and cluster topology details.
Replace Options Indexes with -Indexes in all four shipped Apache config
files (MN and SN, Apache 2.2 and 2.4 variants). Direct file access
by known path continues to work, so all provisioning workflows are
unaffected. Directory browsing for /xcat-doc is preserved as it
contains only public documentation.
Additionally, add an Apache hardening guide documenting recommended
permissions for sensitive directories under /install, network binding
best practices, and IP-based access control options.
Addresses #7450
Docker container lifecycle management (mgt=docker, mkdocker, rmdocker,
lsdocker) was added in 2015-2016 as an experiment targeting Docker API
v1.22 on Ubuntu only. Documentation and man pages were deliberately
removed in 2019 (PRs #6222 and #6324) with the original developer's
approval, noting that "the interface of Docker has become very simple
right now, so there is no value for xCAT to offer such functions."
The plugin was still being shipped but has had no functional code changes
since April 2016, was never listed as a valid mgt value in Schema.pm,
and no user ever filed an issue about it.
Removed:
- xCAT-server/lib/xcat/plugins/docker.pm (1,142 lines)
- xCAT/postscripts/setupdockerhost
- xCAT-server/share/xcat/scripts/setup-dockerhost-cert.sh
- xCAT-test/autotest/testcase/dockercommand/ (test cases)
- Docker attribute definitions in Schema.pm
- Client symlinks (mkdocker, rmdocker, lsdocker)
- Usage entries and dockerhost cert handling in credentials.pm
- Docker attribute documentation in man7 pages
The "Running xCAT in Docker" documentation (dockerized_xcat/) is
retained as it documents containerizing xCAT itself, not the removed
mgt=docker feature.
Closes#7518
