feat(api): add olderThan field to DropCondition for time-based filtering

[Clee2691]

Description

Adds time-based filtering to ClusterLogForwarder drop filters through a new olderThan condition. Values may be specified as YYYY-MM-DD dates or RFC3339 timestamps with explicit offsets; date-only values are interpreted as midnight UTC.

The change updates the API types, CRD schemas, CSV metadata, Vector filter/input configuration, and operator documentation. It also tightens CEL drop-condition validation so each condition must define either olderThan or a field-based match, while preventing invalid combinations such as missing match expressions or simultaneous matches and notMatches.

Testing

Adds coverage for:

• Valid and invalid olderThan formats and timestamps
• Conflicting or incomplete drop conditions
• Application, infrastructure, and audit log filtering
• Boundary behavior around the cutoff timestamp
• Ensuring dropped records remain absent after subsequent log writes

Summary by CodeRabbit

• New Features

  • Drop filters can target records older than a specified date or RFC3339 timestamp.
  • Date-only values are interpreted as midnight UTC; timestamps support explicit offsets.
  • Drop conditions now enforce valid combinations of time-based and field-based criteria.
  • Custom TLS security profiles now support documented ordered group configuration and protocol settings.

• Bug Fixes

  • Improved timestamp handling for host, Kubernetes, OpenShift, OVN, and HTTP audit logs.

AI Description

• Adds olderThan drop conditions for date and offset-aware timestamp cutoffs.
• Normalizes audit timestamps so historical filtering works across supported log sources.
• Tightens schema validation and expands unit, API, and functional coverage.

High-Level Assessment

The following are alternative approaches to this PR:

1. Filter at individual sources

• ➕ Could avoid processing historical records downstream
• ➕ May reuse source-specific age controls where available
• ➖ Not consistently supported across application, infrastructure, and audit sources
• ➖ Cannot compose the cutoff with field match conditions
• ➖ Would duplicate behavior across source implementations

2. Use a relative age duration

• ➕ Convenient for continuously moving retention windows
• ➕ Avoids periodically updating an absolute cutoff
• ➖ Evaluation time introduces changing behavior and replay ambiguity
• ➖ Requires additional duration syntax and validation
• ➖ Does not match the requested deterministic historical boundary

Recommendation: Keep the absolute olderThan condition in the shared drop-filter layer. It provides deterministic, source-independent semantics and composes with existing field conditions; normalizing source event timestamps is the appropriate supporting change for accurate comparisons.

1. HTTP audit records ignore time filters ✓ Resolved 🐞 Bug ≡ Correctness

Description

buildOlderThanCondition evaluates root .timestamp, but the HTTP receiver calls
NewAuditInternalNormalization with parseIntoStructured=false, so its stageTimestamp and
requestReceivedTimestamp are never copied into ._internal.timestamp. ViaQ consequently assigns a
missing timestamp to the root record and the predicate coalesces the parse failure to false,
affecting audit events delivered through the supported HTTP receiver.

Code

internal/generator/vector/filter/drop/filter.go[R56-61]

+func buildOlderThanCondition(olderThan string) (string, error) {
+	cutoff, err := normalizeOlderThan(olderThan)
+	if err != nil {
+		return "", err
+	}
+	return fmt.Sprintf(`((parse_timestamp(to_string(.timestamp) ?? "", "%%+") < t'%s') ?? false)`, cutoff), nil

Relevance

●●● Strong

HTTP audit normalization skips timestamp extraction, so olderThan silently evaluates false for
supported audit records.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

The new predicate reads root .timestamp; the HTTP receiver explicitly disables structured audit
parsing, while the shared normalizer only extracts audit timestamps when that flag is enabled. ViaQ
copies only ._internal.timestamp to the root, and the existing HTTP fixture demonstrates that
received audit events provide stageTimestamp and requestReceivedTimestamp rather than a root
timestamp.

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

Issue description
`olderThan` evaluates `.timestamp`, but HTTP receiver audit events retain their timestamps under `._internal.structured` and never populate `._internal.timestamp`. The filter therefore treats valid HTTP-delivered audit events as having no parseable timestamp and keeps them.

Fix Focus Areas

- internal/generator/vector/input/internal.go[61-72]
- internal/generator/vector/filter/drop/filter.go[56-61]

Recommended Fix
Add receiver-specific audit timestamp normalization that parses `._internal.structured.stageTimestamp`, falling back to `._internal.structured.requestReceivedTimestamp`, and assigns the parsed result to `._internal.timestamp` before ViaQ normalization. Add functional coverage for an HTTP kube-audit receiver with an `olderThan` drop condition.

2. Old invalid filters begin dropping logs ✓ Resolved 🐞 Bug ≡ Correctness

Description

validateDropCondition no longer rejects conditions containing both matches and notMatches,
while generation selects matches and silently ignores notMatches. A resource persisted under the
previous CRD can therefore become operator-valid after upgrade and activate an ambiguous drop rule
because CEL validation is not rerun when controllers read existing objects.

Code

internal/validations/observability/filters/validate_filters.go[L54-56]

-			// Validate only one of matches/notMatches is defined
-			if testCondition.Matches != "" && testCondition.NotMatches != "" {
-				testErrors = append(testErrors, "only one of matches or notMatches can be defined at once")

Relevance

●●● Strong

Removing internal conflict validation lets legacy invalid objects reach generation with matches
silently taking precedence.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

The current validator chooses notMatches for regex compilation but never reports that both
expressions are present, whereas the generator chooses matches first. Existing objects are fetched
and validated internally during reconciliation, so the new API-server CEL rule does not protect
already persisted resources.

## Fix Focus Areas

- internal/validations/observability/filters/validate_filters_test.go[48-120]

3. Invalid cutoffs pass API validation ✗ Dismissed 🐞 Bug ≡ Correctness

Description

The olderThan schema pattern uses [0-2]\d for both clock and offset hours, admitting values from
24 through 29. Values such as 2026-09-16T24:00:00Z and 2026-09-16T00:00:00+24:00 pass API
schema validation but are rejected later by validateOlderThan and Go time parsing during transform
generation, leaving an admitted resource unable to generate collector configuration.

Code

api/observability/v1/filter_types.go[114]

+	// +kubebuilder:validation:Pattern:=`^\d{4}-\d{2}-\d{2}(T[0-2]\d:[0-5]\d:[0-5]\d(\.\d+)?(Z|[+-][0-2]\d:[0-5]\d))?$`

Relevance

●●● Strong

Schema admits hours 24–29 that internal validation rejects, directly undermining the new API
contract.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

The API marker and generated CRD manifests share the permissive hour pattern, while the
controller-side regex restricts offset hours to 00–23 and semantic validation delegates to Go
timestamp parsing. Existing tests explicitly expect offset hour 24 to be rejected internally,
demonstrating that the API schema admits inputs that reconciliation and filter generation cannot
use.

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The API pattern for `olderThan` permits impossible timestamp and timezone-offset hours from 24 through 29. This disagrees with later validation and transform generation, which reject those values after the API server has admitted the resource.

## Fix Focus Areas
- api/observability/v1/filter_types.go[109-116]
- config/crd/bases/observability.openshift.io_clusterlogforwarders.yaml[1127-1133]
- bundle/manifests/observability.openshift.io_clusterlogforwarders.yaml[1127-1133]
- internal/validations/observability/filters/validate_filters.go[19-21]

## Recommended Fix
Replace the clock-hour and offset-hour `[0-2]\d` expressions with `(?:[01]\d|2[0-3])`, regenerate the CRD and bundle manifests, and add API-validation cases proving that a `24` timestamp hour and a `+24:00` offset are rejected.
