Summary

@juan-fdz-hawa — this is the separate OS-version-sorting PR you asked for when reviewing #50743, split out from the software-version-sorting work that shipped in that PR and its follow-up #51878, and covering the issue you asked me to open for this (#51843).

Makes the Version column sortable on:

  • The dashboard's "Operating systems" card
  • The Software > OS page

Both previously sorted only by host count.

Design, addressing your product-input request: you noted that "sorting by version makes sense in a homogeneous collection (inside the same OS)." Comparing versions across different platforms isn't meaningful (e.g. macOS "26.6" vs. Windows "22H1" don't share a scheme), so:

  • Sorting by version groups rows by platform first (most hosts first, direction-invariant), then orders by version within each platform group.
  • The Software > OS page defaults to sorting by version once a single platform is selected (a homogeneous collection, per your note above), and to host count on its "all platforms" view, which is a real, reachable mixed-platform case there.
  • The dashboard card always defaults to version — it only ever renders for a single platform (see below), so there's no mixed-platform case to default away from.

Version comparison, both server-side (server/service/hosts.go) and client-side (OSTableConfig.tsx, for the dashboard card's local sort):

  • Numeric segments compare by magnitude, not lexically ("26.10" sorts after "26.6", not before).
  • Windows feature-update codenames ("21H2", "22H1" — a documented shape of fleet.OSVersion.Version since Enhance API endpoints with host operating systems info #7154) sort by year and half.
  • Ubuntu LTS releases ("22.04.9 LTS") — osquery's os_version table reports a literal " LTS" suffix, which Fleet stores verbatim (SELECT * FROM os_version, no Linux-specific cleanup). Stripped before numeric comparison; without this, Ubuntu LTS rows silently tied as "non-comparable" instead of sorting numerically.
  • Non-comparable formats (e.g. Arch Linux's "rolling") sort before any comparable version rather than erroring.
  • The two implementations are kept deliberately separate from the shared frontend/utilities/helpers.tsx compareVersions helper, which handles messier suffixed software versions but has no concept of OS codenames.

Adds version as a valid order_key for GET /api/v1/fleet/os_versions (API default remains hosts_count descending, unchanged).

Where platform grouping is actually reachable: the dashboard's "all platforms" view never renders the Operating systems card at all (allLayout() in DashboardPage.tsx doesn't include it — only the per-platform layouts do), so the cross-platform grouping branch isn't exercised there. It is reachable on /dashboard/linux: the backend treats platform=linux as a meta-filter matching every actual Linux distro (fleet.IsLinux), so that single "platform" tab can span multiple distinct platform values (e.g. rhel + ubuntu) with different host totals — this is exactly the scenario that caught the Ubuntu LTS bug above, via manual QA on that view (screenshots below).

Known limitation

The dashboard card fetches without page/per_page, so it's capped at the first 20 results (pre-existing, not new to this PR). Since platform-grouping totals are computed from that same capped sample, a platform's total reflects only its loaded rows, not necessarily its fleet-wide count, if there are more than 20 distinct OS-version rows. Flagging proactively rather than leaving it to be found in review.

Summary by CodeRabbit

  • New Features
    • Added OS version sorting on the Dashboard Operating systems card and Software > OS page.
    • Versions sort numerically, including Windows feature updates and Ubuntu LTS releases.
    • Single-platform views default to version sorting; all-platform views default to host count and disable version sorting.
    • Changing platforms resets sorting to the appropriate default.
  • Bug Fixes
    • Version sorting groups platforms by host count, with consistent ordering when host totals are tied.

Adds version sorting to the dashboard "Operating systems" card and the
Software > OS page, which previously only sorted by host count.

Versions sort numerically by segment ("26.10" after "26.6"), Windows
feature-update codenames ("22H1") sort by year and half, and Ubuntu's
" LTS" suffix ("22.04.9 LTS") is stripped before comparing, instead of
sorting as plain strings. Comparing versions across platforms isn't
meaningful, so sorting by version groups results by platform (most
hosts first) before ordering by version within each group.

Adds `version` as a valid `order_key` for `GET /api/v1/fleet/os_versions`.

Walkthrough

The OS versions API accepts version as an order key and compares numeric versions, Windows feature-update codenames, and Ubuntu LTS versions. Version sorting groups platforms by host totals. The dashboard and Software OS tables enable version sorting for selected platforms and use host-count sorting for all-platform views. Platform changes reset sort parameters and table state.

Priority: ➖ Normal

Severity of issue fixed: Medium

Merge Risk: 🟡 Moderate · up to 31f76

Descending version sorting still places unrecognized versions last, contrary to the required ordering, in both the API and dashboard. Correct these ordering paths before merging; the host-count pagination concern predates this change.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 31f76

The change primarily reorders existing OS inventory results while preserving authorization and team filtering. No introduced security issue was established in the inspected path. The additional sorting cost has not been validated under load.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — For the inspected endpoint-to-datastore path, selecting version ordering changes the presentation of OS inventory accessible to the current viewer and team filter, not the set of teams or records the caller is authorized to retrieve. Enterprise delegation preserves this scope.

Trust Boundaries and Controls

  • observed — The caller-controlled order key selects a whitelisted service-side sorting branch. Stored version strings are parsed and compared in memory after authorized retrieval; the new order key and comparison helpers are not forwarded as SQL fragments or executable commands in this path. These authorization and retrieval controls predate the PR and remain unchanged.

Resilience and Maintainability Implications

  • inferred — The sorting branch has no persistent multi-step transition: request failure after sorting does not leave partially committed inventory changes, and concurrent requests do not share the newly allocated result slice. The pre-existing unpaged retrieval remains, while version parsing adds comparison work whose operational cost has not been measured.

Thanks for the contribution @kevinmcox ! To give you a bit of context on our workflow: issues in the "Inbox" lane haven't been triaged yet and aren't ready for development. Only items in the "Ready" lane are open for pick-up.

This should go through product design first (see here for context) - sorting different OSes doesn't make sense to me (i.e. Ubuntu 26 < macOS 27). I'll try to bring this up in our next Design review. On the meantime could you convert this to a draft? Thanks!

TableContainer/react-table only read defaultSortHeader/defaultSortDirection
once, at mount, so when SoftwarePage recomputed its platform-dependent
default sort after a platform switch, the sort indicator (and react-table's
own notion of the active sort) stayed stuck on the previous platform's
sort — the same staleness already worked around on the dashboard's OS
table via a remount key, just not applied here.

Adds an equivalent key={platform} remount and a regression test that
fails without the fix.

Hi @kevinmcox - Could we enable sorting only when filtering by OS? Thanks!

Screenshot 2026-09-14 at 12 39 11 PM

Comparing OS versions across different platforms isn't meaningful
(e.g. macOS "26.6" vs. Windows "22H1"), so the Version column is only
sortable — and only defaults to sorting by version — once a specific
platform is selected. "All platforms" still sorts by host count.

Also closes a URL-based bypass of this restriction: the Software > OS
page is server-driven, so a crafted, bookmarked, or back-button-
restored URL with order_key=version could reach the API even with the
column's sort control disabled. getOSTabSortHeader now guards against
that combination directly.

Thanks for flagging this, Juan — makes sense. I've updated the PR so that sorting by version is only available once a specific platform filter is selected (and becomes the default sort in that case). On "All platforms" the Version column is no longer sortable at all, and it keeps sorting by host count there instead.

Screenshots showing both states are attached: "All platforms" with Version as plain text (no sort control), and macOS selected with Version sortable.

This also covers the Linux filter, which still spans multiple actual OS platforms (RHEL, Ubuntu, etc.) under the hood — sorting by version there groups by platform first (most hosts first), then orders by version within each group, same as before.

One small note about the documentation, other than that lgtm!

That said, would you mind removing the documentation change and creating a separate PR against the docs-v4.94.0 branch? (The reason for that being: documentation changes merged to main go live on fleetdm.com right away, so we use release-specific branches to avoid prematurely documenting features that won't be available until the release goes out.)

Comment thread docs/REST API/rest-api.md Outdated
Removes the documentation change which will be added in a separate PR.

**Related issue:** N/A — documentation follow-up to #53013 (`version`
order_key for OS tables, split out per review feedback)

# Checklist for submitter

- [x] QA'd all new/changed functionality manually — verified live
against a running Fleet server that `GET
/api/v1/fleet/os_versions?order_key=version` returns `200` and correctly
grouped/sorted results, including without a `platform` filter.

## Summary

Documents the `version` `order_key` for `GET /api/v1/fleet/os_versions`,
added in #53013. That PR's docs change was pulled out and moved here at
Rachael's request, since docs merged to `main` publish to fleetdm.com
immediately and this `order_key` isn't released yet.

Targets `docs-v4.94.0` instead of `main` so it goes live with the
release.

3834-3839: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Keep non-comparable versions first in both sort directions.

compareOSVersions("rolling", "26.6") returns -1. For a descending sort, the comparator reverses that result. The descending order then places "rolling" after comparable versions within the same platform group. The required rule is that non-comparable formats sort before comparable versions in both directions. The existing tests do not catch this case. In TestOSVersionsOrderByVersion, "rolling" is the only version on the arch platform, so it never shares a group with a comparable version.
