Ryan Hughes e1fc502286 Nudge the bar over IPC when toggling visibility
The shell notices the bar-off flag through a FileView watch on the toggles
directory, and that watch can permanently stop delivering events after flag
changes land in quick succession — the bar then stays parked off screen
until the shell restarts. Have omarchy-toggle-bar nudge the bar's probe
over IPC after flipping the flag, so the toggle no longer depends on the
watch staying alive. The watch remains for other writers of the flag.

Ryan Hughes 71d7ac81ae Match sshd -T keywords case-insensitively when verifying hardening
OpenSSH 10.x prints configuration keywords in CamelCase in its sshd -T
dump, where 9.x printed them lowercase. The case-sensitive grep in
omarchy-setup-security-sshd therefore never matched on OpenSSH 10.x, so
the hardening drop-in was always judged ineffective and removed, leaving
password authentication enabled.

Ryan Hughes 884ca49340 Point the rc channel at the rc package repository
pacman-rc.conf shipped with [omarchy] on pkgs.omarchy.org/edge — a
leftover from when release candidates published there. Candidates now
publish to a dedicated rc channel, so a machine switched to rc with
omarchy-refresh-pacman was pairing the rc Arch mirror with edge omarchy
packages, and omarchy-version-channel could not name the rc repository
at all (an rc install reported 'rc / unknown').

Point the conf at pkgs.omarchy.org/rc, teach omarchy-version-channel
the rc repository, and repoint existing rc-channel machines with a
migration. The migration only rewrites the shipped pairing (rc mirror +
edge [omarchy]); an administrator's deliberate combination is kept.

625c4a1603 Quote install-app and install-font names like install-and-launch (#7843)
* Quote install-app and install-font names like install-and-launch

* Quote the package list too, not just the display name

The display name was quoted but omarchy-pkg-add's own arguments were still interpolated into the bash -c string raw, so `omarchy install app Vim 'vim; id'` ran id. The list has to reach the helper as several words, so it cannot be quoted whole: it is split the way the unquoted expansion split it and each word is quoted on its own. Reading with -d '' keeps a newline-separated list intact instead of dropping every package after the first, which plain read -a would. install-font's package is singular and is quoted whole, and install-and-launch carried the same flaw.

Reported by acrogenesis in review of #7843.

* Test that install-font skips font-set when pkg-add fails

The hostile-package case was asserting the family still got set, which only held because the mock always exits 0. pacman would reject that name and the && chain would skip font-set.

* Keep the installers working when errexit is inherited

read -d '' always ends at EOF rather than on its delimiter, so it reports failure on every input. Under an inherited errexit the installers exited there and built no command at all.

acrogenesis d593847728 Fail the suite on privileged writes through unquoted heredocs
An installer that writes a root-owned file through a heredoc with an
unquoted delimiter (<<EOF rather than <<'EOF') has the installing user's
shell expand the body first, so a user-controlled value is baked in as a
literal. Send that into /etc and root later reads or executes a path the
unprivileged user picked: a udev rule carrying
$HOME/.local/share/omarchy/bin/... resolves through a symlink that user
owns, so replacing the symlink gets their code run as root.

Add the static check. A heredoc is flagged when its delimiter is
unquoted, its body contains an install-time expansion (escaped \$VAR does
not count, since that is left for a root daemon to expand at runtime),
and its output reaches /etc, /usr, /opt, /srv, /boot or /var/lib via sudo
tee, sudo dd, a redirect, or an install/cp/mv of the generated scratch
file. Destinations written as variables are resolved from the file's own
assignments.

Sites that genuinely need install-time expansion declare it inline:

  # omarchy:heredoc-expands paths=none -- $servers is a validated IP list

paths= is machine-checked against the expansions the scanner finds to be
path-shaped, so this cannot become a rubber stamp: adding a $HOME/... to
an already-annotated heredoc makes the declaration false and trips the
check again. Path expansions anchored under a root-owned prefix, as in
"/etc/systemd/system/$unit", are correctly not path-shaped.

Annotate the sites the scan reports, each of which expands a scalar: DNS
addresses in omarchy-dns, a literal PAM line in
omarchy-setup-security-fingerprint, kernel cmdline parameters and
usernames in omarchy-upgrade-to-quattro. omarchy-provision-owner expanded
a unit name that was already a constant, so its delimiter is now quoted
and the name hardcoded; the generated unit file is byte-identical.
omarchy-windows-vm declares paths=storage,shared, the only site that
interpolates a user-chosen path.

Fixtures prove non-vacuity in both directions: the write routes other
than a pipe into sudo tee, the shapes that must stay quiet, udev rules
and a shutdown unit taken verbatim from this repository's history, and
the rubber-stamp case where a paths=none annotation on a baked $HOME path
still fails.

David Heinemeier HanssonandClaude Opus 5 e47784be11 Name the dev-link authorization when it is the thing that failed
Validating /etc/omarchy.conf walks its parent chain to /, and that walk leaves
its own subject behind in the global failure_context. The comparison that
follows -- the one deciding whether the authorization actually names this
checkout -- sets no context of its own, so an unauthorized development tree
refused with:

  refusing to publish: directory / (must be root-owned and not group- or
  world-writable) failed validation

naming a directory that had just passed, and pointing the reader at a
filesystem problem that is not there. Seen on a worker VM running an
unauthorized checkout, where / is 0555 root-owned.

The hint line underneath was already right, which is what kept this from being
worse. Restore the context before the comparison so the first line agrees with
it, and assert both halves: that the refusal names the authorization, and that
it does not blame the root directory.

David Heinemeier Hansson bf20c94ea0 Merge quattro into the Chromium first-run EULA branch
Quattro stopped making the Chromium managed-policy directory world-writable while this branch was open, and the block it deleted from the theme install leaf sat directly above the comment this branch rewrites, so the two edits landed in one hunk. The resolution keeps the hardening — the policy directory is set up through install/config/browser-policy.sh now — along with the first-run seed and the comment that names both things the seed does.

David Heinemeier HanssonandCodex XHigh 24c18df5b7 Temporarily remove automatic printer discovery
cups-browsed is the daemon that watches the network and creates print queues by itself. Hardening it took a root daemon with a predictable cache down to a confined service account, but a daemon that turns anything advertising itself on the network into a print queue is a lot of exposure for a convenience, so it comes out of the default install while that is reworked. Only the discovery half: CUPS itself stays and printing keeps working, with each printer added by hand in Print Settings.

The migration disables the unit before removing the package because that is the only order that works: pacman deletes the unit file but not the enable symlink, and once the unit is gone systemd can no longer resolve it by name to clean that up.

It then removes the queues discovery generated. cups-browsed keeps those when it stops, since KeepGeneratedQueuesOnShutdown defaults to Yes, and they route through its own implicitclass backend, which goes with the package, so they cannot print again. Idle ones go. A queue with jobs on it is left alone and named: implicitclass only needs cups-browsed to choose a destination, so a job already past that point finishes on its own, and deleting the queue would abort it. One printer's job does not hold up the removal. A printer added by hand has an ipp:// or usb:// device and is left where it is.

A queue whose jobs cannot be asked about is left alone rather than assumed idle, including one named so that lpstat would misread it -- "all" is its word for every destination, and a leading dash or a comma reads as another option or a list.

Where CUPS does not answer at all, or a queue will not delete, discovery is still stopped but the package stays and no marker is written. omarchy-migrate records a migration for the user as soon as it exits zero, so that is where the machine stays until someone removes the package by hand, and the message says so rather than implying a retry.

The queue list is read under LC_ALL=C because lpstat translates "device for", and captured rather than piped, so a cupsd it cannot reach is reported instead of reading like a machine with nothing to clean up.

It removes with plain pacman -R rather than omarchy-pkg-drop, which passes -n and would discard /etc/cups/cups-browsed.conf instead of keeping it as a .pacsave. A removal meant to be temporary should not delete the machine's copy of its own configuration. Without -s either, so it only ever removes the package it names: sweeping newly unneeded dependencies is nothing today, but it is not a promise a rolling dependency graph can keep.

Queue names come off the network, since cups-browsed names its queues after what the printer advertised. CUPS allows every printable character but space, tab, / and #, and lpstat and lpadmin take a destination as an option value, so a name with a leading dash or a comma is reported rather than passed to them and guessed at.

Migration state is per user, so a machine-wide marker records the one removal. Without it, an account whose first migration run came after someone deliberately reinstalled discovery would quietly take it back out again.

The install-time override for cups-browsed.conf now waits for cups-browsed rather than for CUPS. Guarding it on a file CUPS still ships would write a configuration file for a package nothing installed, and pacman would later land the package's own copy beside it as a .pacnew.

The hardened configuration stays in the tree. omarchy-settings still ships the cups-browsed.conf override, the sysusers account and the service drop-in, so they are what discovery returns onto.

David Heinemeier HanssonandClaude Opus 5 d3b7810a76 Say why the privileged Plymouth transaction refused
Every check inside the root shell is a bare [[ ]] or (( )) assertion that
aborts under set -e, so a refusal exited with status 1 and no output at all.
The floating-terminal wrapper then printed its green "Done!" for any status
but 130, so a failed boot-theme change read as a success.

The refusal a working machine actually hits is omarchy dev link, which points
OMARCHY_PATH at a checkout the desktop user owns. Name that case outright and
point at omarchy dev unlink; report every other rejection through an ERR trap
that names what failed validation.

9382410026 Validate the web app URL before anything fetches it
The scheme check ran after the interactive branch, which had already handed the URL to curl: a refused `file://` or `ftp://` URL was dereferenced first, the whole string went out to Google's favicon endpoint in a `domain=` query, and a fetch that happened to succeed left an orphan icon and a rebuilt icon cache behind. Validating immediately after normalization puts the refusal ahead of every dereference in both branches.

A leading space also kept the URL out of the scheme test entirely. `normalize_webapp_url` saw no scheme, prefixed it, and ` file:///etc/passwd` became `https:// file:///etc/passwd`, which passes `^https?://`. The desktop `Exec` field is unquoted, so it splits back into two arguments, and `omarchy-launch-webapp` forwards everything after the first to the browser, where a bare argument is another URL to open. Refusing whitespace closes that without touching desktop-entry escaping.

Scheme comparison is case-insensitive because schemes are: `HTTPS://example.com` installed before this check existed and has no reason to stop.

David Heinemeier HanssonandCodex XHigh 2b923cf5bd Pin the theme name check to C, and read a colon before any slash as scp-style
A bracket range is collated, not ASCII, so `[a-z]` admits `é` under
en_US.UTF-8 and refuses it under C: the same theme URL installed on one
desktop and was refused on the next, and the manual's stated set was only
true in the C locale. Pinning the comparison makes the written set the
shipped one everywhere.

git reads a URL as scp-style when a colon appears before any slash, so the
path after it need not contain one. Requiring a slash left the prefix on
`git@host:omarchy-blue-theme.git` and derived the name
`git@host:omarchy-blue`, which the allowlist then refuses -- a repo that
clones fine could no longer be installed at all.

Keep a web app name out of the launcher's directory structure
2026-08-27 19:40:46 +02:00
9ece53cede Prove the web app name guard, and reject before the icon is fetched
The slash guard was the only thing keeping a name out of the directory structure, and nothing tested it: deleting it left the suite green, because creating the launcher directly in the applications directory already makes the redirect fail on its own, with a raw bash error instead of the message. The assertion is on the message now, alongside the traversal case the guard actually closes -- on quattro a name of `../../../../escaped` writes its launcher clean outside the applications directory.

The interactive prompt read the name, fetched the favicon, wrote it and updated the icon cache before the name was ever checked, so a URL typed into the Name field left an icon behind on every attempt. Validating as soon as the name is read covers both paths from one place.

Removing by name also scanned unconditionally, so a machine with no applications directory printed a find error where omarchy-remove-gaming-xbox-cloud does not hide stderr.

ea6ee9440a Add omarchy-crash-mute to mute and unmute one program
The mute was reachable only as `omarchy-toggle crash-ignore/<program>`, which asks whoever runs it to know the flag layout, to reduce a binary's path to the name the watcher keys on, and to have read the rule that a name climbing out of that directory writes an unrelated toggle. All of that was carried in the skill's prose, which is the wrong place for a rule that has to hold: prose is advice, and the thing being advised about is a name the crashed program chose.

So it is a command now. `omarchy crash mute hyprland` silences that program, `off` lifts it, `toggle` flips it, and no argument lists what is muted. It takes the binary's path as readily as the name and reduces it the way the watcher does, so the `Executable:` line from `coredumpctl` can be handed straight to it; it refuses what is not one component of a name, so it cannot be talked into writing outside its own directory whatever it is given; and it re-reads the flag afterwards and reports what is now true rather than what was asked for. The listing counts only regular files, because that is all the watcher honours -- anything else in there would read as muted while the crashes kept arriving. A leading `--` is consumed so a program named `-h`, which the router would otherwise answer with its own help, can still be muted.

The watcher gained an unrelated fix that this uncovered. Its fields are read with `IFS=$'\t'`, and tab is IFS whitespace, so an empty field collapsed into the next delimiter and shifted every field after it along one: a crash whose comm was empty had a path read as its pid and was discarded as somebody else's. A process can set its comm to nothing, so that was reachable. Empty fields now arrive as a dash like missing ones, and a dash joins the empty and dot cases that fall back to `unknown`.

8d14869689 Let a crash diagnosis mute that program's notifications
A crash that is understood is not a crash that stops: an upstream bug waiting on a release, a program that dumps core every time it exits. The diagnosis explains it once and the toast keeps arriving, and the only answer Omarchy had was Crash Capture, which turns off every program's notifications in order to silence one.

The watcher already resolves a name to dedupe on and announces that same name in the toast, so the mute is keyed on it: a flag file under toggles/crash-ignore/, written by the existing omarchy-toggle and read by the existing omarchy-toggle-enabled. One flag per name rather than one list, so `on` mutes, `off` un-mutes, and `ls -A` shows what is muted, with no new file format and nothing to parse. It is the executable's basename wherever one was recorded, falling back to the process name, which the kernel truncates to fifteen characters -- muting the truncated form would match nothing, forever, while looking like it worked.

The name is not always a name, though, and the mute turns it into a path. A program picks its own comm and prctl takes anything, including slashes, and the watcher falls back to comm whenever a crash carries no absolute executable. So it is stripped to its last component first: without that, `a/../bar-off` is a legal comm aimed at an unrelated Omarchy flag, letting a crashing program suppress its own notification and letting a user who accepted the offered mute hide their bar instead. Stripping does not always leave a component either -- `/` leaves an empty string, which is no kind of array subscript and no kind of toast, and `.` or `..` names a directory that omarchy-toggle would touch and report success on, leaving a mute that never matches. Both fall back to `unknown`, the word omarchy-agent-crash already uses for a name it does not have, and which mutes like any other.

The skill offers this at the end of a diagnosis and never runs it unprompted, which makes it the single change a diagnosis may make to a system it otherwise only reads. It tells the agent to use the name it was handed rather than re-derive one, since the watcher resolved that name already and the two agree for ordinary names and not for strange ones; a diagnosis started by hand from `omarchy agent crash <pid>` is given no name and gets the derivation instead. It also says to treat the name as hostile text rather than as a word -- it is whatever the crashed program's author called a file, so a single quote inside one closes the quotes around it and the rest runs as the shell -- and to check the flag arrived rather than assume it.

Mehmet InceandClaude Opus 5 3b0e899029 Let a theme name hold a plus or lead with an underscore, and document the set
The name a theme installs under is derived from its repo URL, and holding it to
an allowlist made that allowlist a naming convention nobody had written down. It
was also tighter than the harm it exists to stop: `+` is not shell syntax and a
leading `_` is neither the `..` climb nor the dash basename reads as an option,
so `omarchy-c++-theme` was refused for nothing.

Widen the set to those two and say what it is where a theme author is already
picking a name. The leading character stays out of `.` and `-`, which is the
part that does the work.

  generated .desktop (Name/Comment/Icon/MimeType/Exec), with no escaping.
- Adds two spec-level escapers: Desktop Entry string escaping on every
  field (a raw newline could inject a second key line / second Exec=),
  and Exec-argument quoting for the default Exec's URL (spaces, %, reserved
  chars). $CUSTOM_EXEC stays file-syntax-only — it is a full command line
  by design, not a single value.
- No known exploit path: untrusted input reaches these values today only
  via Omarchy literals, interactive gum, or direct CLI. This is
  defense-in-depth for a latent sink.
- Verified end-to-end: generated .desktop has one escaped key per field;
  gio launch passes the URL to omarchy-launch-webapp as a single unchanged
  argument (Sunshine literal and normal gum path both byte-identical).
