2021-08-08seatd: Use path in chmod/chown operationsKenny Levinsen
c8b3a22d4ef0f69c3d22f0ec1170b89c93ef1dc3 snuck in a change which converts chown/chmod to fchown/fchmod using the socket fd. This appears to succeed under Linux, but fails with EINVAL on FreeBSD. As the error handling in this area was flawed, CI failed to catch the regression. Partially revert c8b3a22d4ef0f69c3d22f0ec1170b89c93ef1dc3 to fix the regression on FreeBSD.
2021-08-08seatd: Improve socket permission error handlingKenny Levinsen
chmod/chown errors were logged, but did not result in failure opening the seatd socket. This meant that errors would not get caught by CI.
2021-08-06seatd: Only set UID/GID when specifiedKenny Levinsen
The UID/GID defaulted to 0, which results in trying to chown to root when a UID or GID isn't requested. Instead, deafult to -1 so that the unspecified values are left intact.
2021-08-06seatd: s6-style readiness notification supportKenny Levinsen
This adds the ability to specify the number of an fd that is inherited by the process as open. Once seatd is read to serve requests, it will write a single newline and close the fd.

2021-02-27seatd: Close cur_ttyfd in seat_destroyKenny Levinsen
This fd would only still be set after closing clients if no clients were active on the current VT.
2021-02-27client: Remove link if seat_add_client succeedsKenny Levinsen
Removing the link before before means that we can return without a link, resulting in a double-remove.
2021-02-27seatd: Clean up debug logs a bitKenny Levinsen
2021-02-27Convert a few debug logs to error logsKenny Levinsen
2021-02-27seatd: Set errno in seat_add_clientKenny Levinsen
2021-02-27seatd: Tear down VT when disabled client closesKenny Levinsen
If a client closed while it was disabled, the VT would not be torn down. If the user navigated back to the VT it belonged to, they would be stuck. When a client is disabled, open the fd for the VT it belonged to and perform regular teardown on it.
2021-02-27client: Replace pending_disable with state enumKenny Levinsen
This simplifies logic in seat handling.
2021-02-02seat: Remove unused arg from seat_deactive_deviceKenny Levinsen
2020-12-10client: Fix typo in cr_pid usageKenny Levinsen
2020-12-08client: Use cr_pid if availableKenny Levinsen
This is only available on FreeBSD 13, so test for that version.
2020-12-08client: Do not use SOL_SOCKET for LOCAL_PEERCREDKenny Levinsen
This is wrong, and leads to LOCAL_PEERCRED being interpreted as SO_DEBUG. 0 should be used instead. See: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=246189.
2020-11-23client: More robust handling of client linksKenny Levinsen
2020-11-23poller: Retry poll immediately on EINTRKenny Levinsen
There is nothing for us to dispatch unless we wake on an fd, so just retry poll if it fails with EINTR instead of doing a full dispatch loop.
2020-09-22seat: Only close VT if no new session was foundKenny Levinsen
2020-09-22terminal: Ack both release and acquireKenny Levinsen
Linux only requires acking release and ignores ack of acquire, but FreeBSD is more stringent and will patiently wait for both to be acked. Implement proper acking for both events.
2020-09-22seat: Use current VT for switch and ackKenny Levinsen
2020-09-22meson: Make default seatd socket path configurableKenny Levinsen
FreeBSD and Linux have different preferred socket locations. Expose an option to set the location, and implement simple auto-logic for linux/freebsd.
2020-09-22poller: Add unittestKenny Levinsen
2020-09-22seatd: Log on exitKenny Levinsen
2020-09-22seat: Reuse deactivate logic, more loggingKenny Levinsen
2020-09-22seat: Plug leak of deactivated fdsKenny Levinsen
Only if a device had an fd and was active would an fd be closed. As devices are deactivated early on session switch, this lead to fd leakage. Close fds regardless of active state.
2020-09-22seat: Rework seat activation/switch logicKenny Levinsen
The seat activation logic did not correctly handle VT switching and switching between multiple sessions. Session switching on VT-bound seats is now performed using a VT switch, taking advantage of VT signals to perform the actual switch. This simplifies switching logic and makes it more robust.
2020-09-22client: Remove unnecessary active_client checkKenny Levinsen
2020-09-22poller: Raise signals through self-pipeKenny Levinsen
Signal handling relied on poll(2) being interrupted by signals, followed by a check for signal handlers flagging a signal as received. This only allowed signals that were received during poll(2) to be handled correctly. Implement the usual self-pipe implementation, where signal handlers write an arbitrary byte to a polled file descriptor to ensure proper level-triggered signal handling.
2020-09-01client: Only unlink if on the idle listKenny Levinsen

Silences a warning on some architectures.

2020-08-29seat: Destroy all clients on teardownKenny Levinsen
2020-08-28Introduce libseat_set_log_levelSimon Ser
The default level is SILENT. log_init no longer takes an initial log level (so that calls to libseat_set_log_level prior to log_init work correctly).
2020-08-28Rename enum log_level to libseat_log_levelSimon Ser
This is preparatory work for exposing a public function to set libseat's log handler.
2020-08-08seatd: Use path-based chmod/chownKenny Levinsen
The fd variants do not seem to work for sockets
2020-08-07seatd: Add command-line argumentsKenny Levinsen
