Checklist for submitter

If some of the following don't apply, delete the relevant line.

  • Changes file added for user-visible changes in changes/, orbit/changes/ or ee/fleetd-chrome/changes.
    See Changes files for more information.

  • Input data is properly validated, SELECT * is avoided, SQL injection is prevented (using placeholders for values in statements), JS inline code is prevented especially for url redirects, and untrusted data interpolated into shell scripts/commands is validated against shell metacharacters.

  • Timeouts are implemented and retries are limited to avoid infinite loops

  • If paths of existing endpoints are modified without backwards compatibility, checked the frontend/CLI for any necessary changes

Testing

For unreleased bug fixes in a release candidate, one of:

  • Confirmed that the fix is not expected to adversely impact load test results
  • Alerted the release DRI if additional load testing is needed

Frontend

  • Attached a screenshot or screen recording of each user-visible change. For changes to existing UI, show the before and after.

Database migrations

  • Checked schema for all modified table for columns that will auto-update timestamps during migration.
  • Confirmed that updating the timestamps is acceptable, and will not cause unwanted side effects.
  • Ensured the correct collation is explicitly set for character columns (COLLATE utf8mb4_unicode_ci).
  • Ensured the migration can be retried if it was partially applied after a failure.

New Fleet configuration settings

  • Setting(s) is/are explicitly excluded from GitOps

If you didn't check the box above, follow this checklist for GitOps-enabled settings:

  • Verified that the setting is exported via fleetctl generate-gitops
  • Verified the setting is documented in a separate PR to the GitOps documentation
  • Verified that the setting is cleared on the server if it is not supplied in a YAML file (or that it is documented as being optional)
  • Verified that any relevant UI is disabled when GitOps mode is enabled

fleetd/orbit/Fleet Desktop

  • Verified compatibility with the latest released version of Fleet (see Must rule)
  • If the change applies to only one platform, confirmed that runtime.GOOS is used as needed to isolate changes
  • Verified that fleetd runs on macOS, Linux and Windows
  • Verified auto-update works from the released version of component to the new version (see tools/tuf/test)

Summary by CodeRabbit

  • Bug Fixes
    • Windows devices with BitLocker enabled but missing startup protectors are no longer incorrectly shown as “Verified.”
    • Fleet now detects and repairs missing startup protectors, including when protection is already enabled or a restart is pending.
    • BitLocker status updates more accurately reflect whether a device can unlock its encrypted volume at startup.
    • Failed key escrow attempts retain the rotated key for retry, preventing key loss during recovery.

Deleting the TPM and TPM+PIN protectors leaves the volume encrypted with
protection still on and only a recovery password left, so the next restart
goes to the 48-digit prompt. Every existing repair path is gated on
protection being off, so Fleet reported the host as verified and did
nothing, and with a required startup PIN it told the end user to create one
through a Windows dialog that is not offered without a TPM protector.

Report whether a protector able to unseal the volume at boot is present, so
Fleet can see the state at all, hold the host in enforcing while it repairs
it, and have the agent add a protector without touching protection itself.
A host that has not reported the new signal is unaffected.
The two problems this branch fixes belong with the other #52159 entries
rather than in files of their own.
The Go list this query mirrors already counts an external startup key as
able to unseal at boot, so a volume protected only by a USB startup key
was still treated as having nothing.
Three small items plus one edge case, all raised in review of the PR this
branch is stacked on.

Collapse the duplicated boot-protector loop so the list is walked in one
place. Log a paused decryption at Warn rather than Error, since the agent
has not failed at anything there, it is declining to touch a volume only a
person can resolve, and the existing backoff already holds the message to
once per Frequency.

Gate the two new keyless error reports on a server capability. A server
without it overwrites the stored key with the empty value such a report
carries, so a new agent talking to an older server would take the only
recovery key Fleet can show an admin away from a host that is still
encrypted. Staying silent leaves the admin with a key rather than none.
Four discovery clauses carried a verbatim copy of the same two-branch check
for whether BitLocker is usable on the host. Name it once, and let the two
queries whose only precondition is that check share a single clause.

The copy inside disk_encryption_windows is deliberately left alone: it is a
bl_available CTE gating result rows, not a discovery clause gating whether
the query runs at all.
The query encoded its answer in whether a row came back, which cannot
distinguish "this volume has no boot protector" from "the protector list
could not be read". The bitlocker_key_protectors extension returns zero rows
and no error when its PowerShell call produces no output, so a host whose
BitLocker service was unavailable would have been recorded as having no boot
protector, moved to enforcing, and told to repair a healthy volume.

Always return the single row, read the value, and leave the column NULL on
anything unexpected, which already reads as nothing to act on.
"until one exists" attached to the nearest noun, so it read as "no way to
create a PIN until a PIN exists". Say what actually has to exist, and match
the phrasing the sibling message already uses.
…or-missing

# Conflicts:
#	server/datastore/mysql/schema.sql
#	server/fleet/capabilities.go
Matches the convention the surrounding migrations use, including the one
immediately before this on main, so a re-run is a no-op rather than an
ALTER TABLE failure.

1. Failed repairs abandon recovery access 🐞 Bug ☼ Reliability
Description
attemptEnableBitlockerProtection returns immediately when protection and a boot protector are
present, without checking whether the preceding repair still needs to create a recovery password.
When adding the TPM protector succeeds but recovery-key rotation fails, later polls take this return
path, the persisted boot signal eventually stops the notification, and Fleet can show the host as
verified while its escrowed password no longer matches any protector.
Code

orbit/pkg/update/notifications.go[R698-701]

+	if hasProtector && protectionAlreadyOn && w.pendingRecoveryKey == "" {
+		log.Debug().Msg("BitLocker protection is already on and the volume can unseal at boot, nothing to repair")
+		w.protectionRetryAfter = time.Now().Add(w.Frequency)
+		return
Evidence
The new early return considers only protection, boot-protector presence, and pendingRecoveryKey;
the recovery-password check occurs later. Rotation failure returns before setting
pendingRecoveryKey, so the next pass sees the newly added protector and exits. Server notification
logic stops requesting repair after the boot-protector observation becomes true, while verified
status requires a decryptable stored key but does not prove that key still exists on the volume.

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

## Issue description
A repair that adds the missing boot protector but then fails to create a recovery password is treated as complete on subsequent polls. The early return must not suppress recovery-password repair after this partial failure.
## Fix Focus Areas
- orbit/pkg/update/notifications.go[696-750]
## Recommended Fix
Track that recovery-password creation remains incomplete, or verify recovery-password presence before taking the healthy-volume early return. Preserve that state across retry passes until rotation and escrow succeed, and add a test where TPM creation succeeds, recovery-key rotation fails once, and the next pass retries rotation instead of returning early.

2. Unknown protection is reported restored 🐞 Bug ≡ Correctness
Description
attemptEnableBitlockerProtection defines every protection status other than the explicit off value
as already on. If the COM call returns an unknown or otherwise unexpected raw status, the repair
skips restart safeguards and EnableProtection, then reports a successful restoration after only
handling protectors and recovery-key escrow.
Code

orbit/pkg/update/notifications.go[R661-663]

+	// Protection being on does not mean the volume is healthy. Deleting the TPM and TPM+PIN protectors leaves protection
+	// on with only a recovery password, and that volume boots straight to the 48-digit prompt.
+	protectionAlreadyOn := status.ProtectionStatus != bitlocker.ProtectionStatusOff
Evidence
The repository defines only explicit off and on constants, but the COM implementation copies the raw
WMI integer into EncryptionStatus without validation. The changed condition classifies every other
integer as on, and the later branch only calls EnableProtection when that classification is false
before unconditionally reporting restored.

orbit/pkg/bitlocker/bitlocker_management_windows.go[322-337]
orbit/pkg/update/notifications.go[753-765]

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 repair path treats any protection status other than zero as enabled even though the volume status stores an unvalidated raw COM value. Unknown values must not produce a successful restoration report or skip the protection-enabling operation.
## Fix Focus Areas
- orbit/pkg/update/notifications.go[661-665]
- orbit/pkg/bitlocker/bitlocker_management.go[84-89]
## Recommended Fix
Compare explicitly with both the on and off constants. When the value is neither recognized state, report or log that protection status could not be determined, apply retry backoff, and make no volume changes; add a test using an unexpected status value.

Review Change StackReview Change Stack

Walkthrough

The change records whether Windows BitLocker volumes have startup-unlocking protectors. Discovery persists this state through MySQL and Redis. MDM status classification no longer marks volumes without protectors as verified. Orbit repairs missing protectors while preserving active protection, retries failed escrow, and avoids keyless error reports when the server cannot retain the existing key. Tests cover discovery, persistence, classification, repair, escrow, and capability behavior.

Priority: ➖ Normal

Severity of issue fixed: Medium

Merge Risk: 🟠 High · up to 2bd22

The current repair flow can leave hosts without a usable recovery password, erase an older server's escrowed key, and report incorrect repair state. These issues should be fixed before merge.

Explanation

The description includes the related issue and the repository template, but it provides no implementation summary and leaves all checklist and testing items unchecked. It does not provide enough information to confirm completion of the required checks.

Full details: Linked Issues check

Explanation

The available whole-PR summary does not show the required implementation for #49133. It shows BitLocker boot-protector detection, repair, status, escrow, schema, and migration changes. It does not show POST /api/fleet/orbit/disk_encryption_pin, the elevated fleetd PIN handler, the Fleet Desktop login prompt and PIN modal, authorization and premium checks, legacy-version fallback, or PIN-flow automated tests. The excluded OpenSpec files cannot establish that these coding requirements are implemented.

Resolution

Implement and test the #49133 flow. Add the orbit endpoint and elevated fleetd handling. Add the Fleet Desktop prompt, PIN and confirmation validation, permission and state gating, legacy fallback, administrator compatibility, success and error handling, recovery-key escrow, UI clearing, and relevant end-to-end coverage.

Explanation

The PR changes target missing BitLocker startup-protector detection and repair under changes/52159 and orbit/changes/52159.

The summary provides no concrete connection between these changes and the non-administrator PIN creation flow in #49133.

Resolution

Remove or move the #52159 boot-protector repair, schema, migration, and related test changes to the appropriate pull request. Keep only changes that directly implement or support #49133, or link the separate requirement if this combined scope is intentional.

Handle only ProtectionStatusOn as enabled.

ProtectionStatus can be BitLockerProtectionStatusUnknown (2). The current comparison treats it as enabled, skips execEnableProtectionFn, and can report DiskEncryptionProtectionRestored after adding a protector. Compare explicitly with bitlocker.ProtectionStatusOn; treat other values as unreadable or unsupported.

Run recovery-password verification before the healthy-volume return.

When protection is already on and execAddTPMProtectorFn adds the boot protector, a rotation failure leaves pendingRecoveryKey empty. The next invocation then returns at hasProtector && protectionAlreadyOn && pendingRecoveryKey == "" before checking or rotating the recovery password. The missing recovery password remains unrepaired unless another state change breaks that condition. Move this return below the recovery-password verification and escrow path.

Clear the failure state only for a confirmed boot protector.

In MySQL, NOT (bitlocker_boot_protector_set <=> 0) is true for both 1 and NULL. The discovery path leaves this column NULL when the protector state is unknown. A subsequent protection-on report can therefore clear bitlocker_protection_error and bitlocker_protection_outcome before protector presence is confirmed.

Use an explicit true check, such as bitlocker_boot_protector_set <=> 1. Keep the existing encryption-disabled branch. Add regression coverage for true, false, and NULL states.

Proposed fix
- bitlocker_protection_error = IF((VALUES(bitlocker_protection_status) = ? AND NOT (bitlocker_boot_protector_set <=> 0)) OR NOT VALUES(encrypted), NULL, bitlocker_protection_error),
- bitlocker_protection_outcome = IF((VALUES(bitlocker_protection_status) = ? AND NOT (bitlocker_boot_protector_set <=> 0)) OR NOT VALUES(encrypted), NULL, bitlocker_protection_outcome),
+ bitlocker_protection_error = IF((VALUES(bitlocker_protection_status) = ? AND bitlocker_boot_protector_set <=> 1) OR NOT VALUES(encrypted), NULL, bitlocker_protection_error),
+ bitlocker_protection_outcome = IF((VALUES(bitlocker_protection_status) = ? AND bitlocker_boot_protector_set <=> 1) OR NOT VALUES(encrypted), NULL, bitlocker_protection_outcome),
