lint-rules.h was a project-local copy of the Catcrafts house-style
rules. The rules have their own repository now, and project.cpp imports
them from it (`#pragma crafter dependency`), as Crafter.Build's own
project.cpp does. The dependency is pinned to a commit; crafter-build
clones it whenever it loads project.cpp, so every build fetches it,
CI's included.
The tree does not pass the shared rules yet: `crafter-build lint`
reports 72 findings where the copy reported 20. The shared `naming`
wants camelCase constants and statics (44), `const-local` is new (10),
and `single-declaration` reports two files the copy did not. They are
left for a later change; CI does not run lint.
Tested: build-package.sh run end to end on this commit in a privileged
alpine:edge container (podman) on the workstation, and `crafter-build
lint` on a built copy of this commit.
The system-bus policies granted net.catcrafts.IMS1 and org.ofono to root
and to the account `user`, postmarketOS's default name, so on a unit
whose account is called something else dbus denied every Dial from the
dialer — nothing in imsd's journal, nothing on screen. A field user
found it by trial (alyx report 14, 2026-09-20; ims ledger F14).
Let any local account reach both names and have the daemons decide:
placing, answering or ending a call needs polkit's
net.catcrafts.IMS1.Voice (the active local session; not an ssh login, an
inactive session or a system service account). imsd-ofonod asks about
its own callers, since its calls reach imsd as root. Reads such as the
status and the call list are not gated, and a refusal is logged with the
sender; a `--session` run, the development mode without root or polkit,
leaves the gate off. The check is ImsdBus, a small GLib module both
daemons link; the package depends on polkit.
An upgrade restarts both daemons (the previous commit), so the open
policy faces the old, ungated daemons only until the apk transaction
ends.
Tested on the dev phone (KPN) in builds of this series; not every path
has run there.
imsd-ofonod presents imsd on the system bus as an oFono modem — Manager at
/, Modem + VoiceCallManager at /imsd, a VoiceCall object per call — which
is what GNOME Calls' bundled ofono provider drives; Calls, Phosh and GNOME
Shell run unmodified. org.gnome.Calls is not a seam a third party can
provide (Calls exports it, nothing feeds it), and Calls' provider plugins
link private headers, so org.ofono is the only D-Bus contract available.
Pure GDBus translation of net.catcrafts.IMS1, no core, like imsd-dialerd.
Packaged as the opt-in imsd-ofono subpackage: the daemon, its unit
(Conflicts=ofono.service), the system-bus policy and a gschema override
that points Calls at the ofono provider instead of mm (the ModemManager
origin would offer the modem's CS voice path, which carries no audio on
these phones). The policy grants root send_destination=org.ofono: under
dbus-broker a broadcast is checked against the sender's send policy for
every name the receiver owns, so without it imsd's call signals never
reach the daemon.
Verified on a Fairphone 6 with GNOME Calls 50.0: outgoing and incoming
calls with audio both ways, answered and hung up through
org.gnome.Calls.Call. Known Calls-side gap documented in the README: after
the VoiceCallManager interface is withdrawn and re-added, Calls keeps the
old origin's CallAdded handler and eventually crashes.
Userspace VoLTE/IMS daemon for mainline Linux phones (developed on the
Fairphone 6): a GLib-free core (SIP, SDP, USIM AKA, IPsec SA setup, RTP
media, call engine) behind a GDBus control daemon, a standalone AMR-WB
media leg, and a Plasma Dialer backend. C++26 modules built with Crafter
Build; the tree is clean under the project's house-style linter
(crafter-build lint) across all three build products.
