* Improve IPv6 support in RRDtool proxy and ping utilities
- Fix RRDtool proxy to dynamically detect IPv6 addresses and use
AF_INET6 sockets instead of hardcoded AF_INET (IPv4-only), enabling
connections to IPv6 RRDtool proxy servers including backup servers
- Strip brackets from IPv6 addresses before passing to socket_connect
- Properly close failed sockets before creating new ones for failover
- Replace fragile str_contains(':') IPv6 detection in ping with
filter_var(FILTER_FLAG_IPV6) for more robust address validation

* Fix JS code quality: implicit globals, deprecated APIs, loose equality
- Add var declarations to prevent implicit globals in install.js
(element, enabled, button, buttonCheck)
- Remove console.log debug output left in production (install.js)
- Replace deprecated jQuery .unbind() with .off() (layout.js)
- Fix "depreciated" typo to "deprecated" in deprecation warnings
- Convert == / != to === / !== for null, boolean, string, typeof,
and numeric comparisons across install.js and realtime.js
https://claude.ai/code/session_01SbuDigvAkYvPKvdcougsdo
* Replace deprecated jQuery shorthand event methods in layout.js
Replace .click(), .keyup(), .keydown(), .mousedown(), .mouseenter(),
.mouseleave(), .submit(), .resize() with .on() equivalents. Replace
.focus(), .change() trigger calls with .trigger(). These shorthands
were deprecated in jQuery 3.5.
https://claude.ai/code/session_01SbuDigvAkYvPKvdcougsdo
* Replace deprecated jQuery methods in realtime.js
Replace .bind() with .on() and .change() trigger calls with
.trigger('change'). .bind() was deprecated in jQuery 3.0 and
shorthand triggers in jQuery 3.5.
https://claude.ai/code/session_01SbuDigvAkYvPKvdcougsdo
* Replace deprecated jQuery methods in install.js and fix ===/!== errors
Replace .click(), .change(), .focus() with .on()/.trigger() equivalents.
Also fix !=== and ==== operators that were incorrectly introduced by a
prior replace-all of == to === within existing !== and === expressions.
https://claude.ai/code/session_01SbuDigvAkYvPKvdcougsdo
* Restore == null where needed to catch both null and undefined
In JavaScript, == null matches both null and undefined, which is an
intentional idiom. The prior === null conversion broke cases where
values come from jQuery .val(), .data(), $.urlParam(), or object
property access that may return undefined rather than null. Revert
those specific cases while keeping === null where variables are
explicitly initialized to null.
https://claude.ai/code/session_01SbuDigvAkYvPKvdcougsdo
* Replace deprecated jQuery methods in all theme main.js files
Replace .unbind().click() with .off('click').on('click'), convert
.hover() to .on('mouseenter').on('mouseleave'), replace .change(),
.scroll(), .click() shorthands with .on() equivalents, and .blur()
with .trigger('blur') across all 10 theme files.
https://claude.ai/code/session_01SbuDigvAkYvPKvdcougsdo
* Convert string concatenation to template literals
Replace 'str' + var + 'str' patterns with ES6 template literals
in realtime.js and install.js. Improves readability especially for
URL construction and HTML building. Also replace $.parseJSON() with
native JSON.parse() in realtime.js.
https://claude.ai/code/session_01SbuDigvAkYvPKvdcougsdo
* Convert var to const for single-assignment variables
Replace var with const where the variable is assigned once and never
reassigned within its scope, in install.js and realtime.js. Keeps var
for variables that are conditionally reassigned (e.g. size, url).

remote_client_authorized() previously open-coded hostname matching with gethostbyaddr/gethostbyname and an unscoped string compare. Route both the forward-match and the poller/whitelist check through the side-effect-free helpers from lib/security_validation.php so the host-auth logic is unit-testable and the call site shrinks. Depends on Cacti#7068 landing first (introduces the helpers). Signed-off-by: Thomas Vincent <thomasvincent@gmail.com>

Pull request overview
This PR is intended to harden remote_agent.php ingress authorization by routing host/IP verification through newly introduced cacti_remote_agent_* helper functions (from the dependent PR #7068), and includes several additional security/maintenance changes across JS, networking, CI, and UI text.
Changes:
- Update
remote_agent.phpauthorization flow to use forward-DNS verification + centralized “authorized host” logic (dependency onlib/security_validation.php). - Additional remote-agent hardening (session-based effective user; stricter SNMP OID validation).
- Broad set of unrelated refactors/fixes: IPv6 socket handling, UI JS event binding updates, workflow/dependabot configs, and multiple text/spelling corrections.

Dependabot is configured to scan the npm ecosystem at the repository root, but this repo does not contain a package.json/lockfile at /. This will cause Dependabot runs to error/no-op; either add the appropriate manifest/lockfile, point Dependabot at the correct directory, or drop the npm entry and keep only github-actions.

The PR description says this change only wires remote_agent.php, but this PR also modifies many unrelated files (RRD proxy IPv6 handling, ping IPv6 detection, lots of JS event binding refactors, CodeQL/Dependabot configs, and multiple text fixes). Please update the PR description/scope to match, or split these unrelated changes into separate PRs to keep review and risk manageable.

The new OID validation rejects leading-dot OIDs (e.g. .1.3.6.1...), which are common in SNMP. Since the codebase already has cacti_snmp_validate_oid() that supports a leading dot, consider using that helper (or allowing an optional leading dot) instead of '/^[0-9.]+$/' to avoid breaking valid requests.

Same issue as get_snmp_data(): the new regex validation will reject valid leading-dot OIDs. Prefer cacti_snmp_validate_oid() (or equivalent) so legitimate OIDs like .1.3.6.1... continue to work while still blocking non-numeric input.

There was a problem hiding this comment.
This test case is currently a placeholder (expect(true)->toBeTrue()) and does not exercise the new hostname/IP authorization logic (forward DNS match + poller/whitelist checks) described in the PR. Please replace it with real functional coverage (e.g., by factoring the auth logic into a testable helper and stubbing DNS/DB inputs) so regressions in remote agent authorization are caught.

There was a problem hiding this comment.
__rrd_proxy_init() now uses AF_INET6 directly when the server is an IPv6 literal. Elsewhere in the codebase (e.g. ping sockets) IPv6 socket creation is guarded with defined('AF_INET6') to avoid fatal errors on builds without IPv6 constants. Please add the same guard/fallback here to prevent a hard failure when IPv6 support is missing.
