2022-07-12fix: remove redundant empty statement in main.czkldi
This semi-colon looks like a typo. Luckily, it has no effect on the code as it's treated as an empty statement leading the switch case. Really straightforward nitpick change, was just something I was confused by when reading over the code.
2022-06-03Refuse to start when SUID is detectedKenny Levinsen
This ensures that those surprised by the deprecation of SUID operation receive an error rather than accidentally having sway run as root. This detection will be removed in a future release.
2022-05-18realtime: request SCHED_RR using CAP_SYS_NICERouven Czerwinski
Try to gain SCHED_RR (round-robin) realtime scheduling privileges before starting the server. This requires CAP_SYS_NICE on Linux systems. We additionally register a pthread_atfork callback which resets the scheduling class back to SCHED_OTHER (the Linux system default). Due to CAP_SYS_NICE, setting RLIMIT_RTPRIO has no effect on the process as documented within man 7 sched (from Linux): Privileged (CAP_SYS_NICE) threads ignore the RLIMIT_RTPRIO limit; as with older kernels, they can make arbitrary changes to scheduling policy and priority. See getrlimit(2) for further information on RLIMIT_RTPRIO Note that this requires the sway distribution packagers to set the CAP_SYS_NICE capability on the sway binary. Supersedes #6992
2022-03-29sway/main: move constants off the stackManuel Stoeckl
This makes stack traces from gdb slightly easier to read.

2022-01-11Print deprecation notice when running SUIDKenny Levinsen
SUID privilege drop is needed for the "builtin"-backend of libseat, which copied our old "direct" backend behavior for the sake of compatibility and ease of transition. libseat now has a better alternative in the form of seatd-launch. It uses the normal seatd daemon and libseat backend and takes care of SUID for us. Add a soft deprecation warning to highlight our future intent of removing this code. The deprecation cycle is needed to avoid surprises when sway no longer drops privileges.
2021-11-14sway: allow IPCs on proprietary driversEric Engestrom
Proprietary drivers require --unsupported-gpu to be allowed, and IPCs require no option to be passed. The only way to satisfy both is to run IPCs before checking for proprietary drivers.
2021-10-30Bump RLIMIT_NOFILESimon Ser
Wayland compositors handle many file descriptors: client connections, DMA-BUFs, sync_files, wl_data_device pipes, and so on. Bump the limit to the max. Closes: https://github.com/swaywm/sway/issues/6285
2021-10-19Remove --my-next-gpu-wont-be-nvidiaSimon Ser
Nvidia has historically been a bad actor in the open-source graphics ecosystem because they required a special EGLStreams code-path instead of exposing the de-facto standard GBM API. However, with their upcoming release they now support GBM as well. This is a push in the right direction for Nvidia, so there's no reason we should be more hostile to them than to any other proprietary driver. Let's remove the --my-next-gpu-wont-be-nvidia flag, and advise users to use --unsupported-gpu now. Note, proprietary Nvidia drivers are still unsupported by the Sway project (just like all other proprietary drivers).

Can be useful to make sure a bugfix is included. In the future maybe the wlroots version string could include a commit hash when built from source, too.

2020-12-09Route wlroots logs into Sway logging infrastructureSimon Ser
Instead of letting wlroots print messages to stdout, route debugging messages into Sway's logging functions. This allows a more consistent output (e.g. if Sway or wlroots changes its output style, they don't get out-of-sync). I also added a [wlr] prefix to wlroots messages, not yet sure it's a good thing.
2020-08-11Handle SIGINTSimon Ser
Gracefully exit on SIGINT, like we do for SIGTERM.
2020-07-30Log empty value if envvar is not definedAntonin Décimo
If the environment variable is not defined, getenv returns NULL. Passing a NULL pointer to the "%s" format specifier is undefined behavior. Even if some implementations output "(null)", an empty string is nicer.

2020-02-11config: fix validation exit code and log levelBrian Ashworth
This makes it so invalid configs will return the exit code 1 when the validation flag is given. This also reduces the log level to SWAY_ERROR, which makes it so only the errors are shown. If someone wants more verbose output, the can use the -V/--verbose or -d/--debug flags. Additionally, this also makes it so swaybg will not be spawned when validating the config.
2020-02-11Fix ordering of setgid and setuidTeddy Reed
It looks like the code to drop privileges may have been broken via commit 37f0e1f. That commit reverted the correct order from #911, which first drops the gid then the uid. If setuid is called first then the target user may not have the ability to setgid.

2019-06-12bindings: defer while initiailizingBrian Ashworth
This adds the logic to defer binding execution while sway is still initializing. Without this, the binding command would be executed, but the command handler would return CMD_DEFER, which was being treated as a failure to run. To avoid partial executions, this will defer all bindings while config->active is false.

2019-02-11Abort early when XDG_RUNTIME_DIR is not setBrian Ashworth
This aborts sway and displays an error message about XDG_RUNTIME_DIR not being set without initializing the wl_display or logging any other information.
2019-02-06Clarify error for options and positional argsBrian Ashworth
When both options and positional arguments are given, sway would print the error `Don't use options with the IPC client`. Over the past several months, it seems like users are including this error message in issues instead of a debug log due to not understanding that the error message means there is an issue with their command. This makes the error message more verbose and will hopefully make it so more users understand that the message is not a bug in sway, but with the command used.

2019-01-29Cleanup config reading failure error logsBrian Ashworth
This cleans up the log when sway fails to read a config file. The following changes have been made: - A missing error message has been added to the log when the config file is a directory instead of a regular file - In main, `goto` statements have been added after the `sway_terminate` calls instead of wrapping every block in `if (!terminate_request)` - Unnecessary NULL-checks around calls to free in `main` have been removed - Deferred command execution has been extracted to a separate function and the `Running deferred commands` log message will not be shown when there are no deferred commands.
2019-01-28Cleanup log_envemersion
SWAY_CURSOR_* are not used anymore. LD_PRELOAD_PATH doesn't exist and has been replaced with LD_PRELOAD.
2019-01-21Replace wlr_log with sway_logM Stoeckl
This commit mostly duplicates the wlr_log functions, although with a sway_* prefix. (This is very similar to PR #2009.) However, the logging function no longer needs to be replaceable, so sway_log_init's second argument is used to set the exit callback for sway_abort. wlr_log_init is still invoked in sway/main.c This commit makes it easier to remove the wlroots dependency for the helper programs swaymsg, swaybg, swaybar, and swaynag.
2019-01-15Do not send ipc_event_shutdown from ipc clientBrian Ashworth
In `sway_terminate`, `ipc_event_shutdown` was being sent regardless which mode sway was running in. When running as an ipc client, `sway_terminate` should just exit

2018-10-21Abort if proprietary drivers are in useRyan Dwyer
The idea here is we don't want users to be blissfully unaware that they are running unsupported drivers. So we abort on startup, and force the user to add a specific argument to bypass the check.

2018-09-30Add support for installing binaries with DT_RPATHArkadiusz Hiler
It's better to use DT_RPATH dynamic section of the elf binary to store the paths of libraries to load instead of overwriting LD_LIBRARY_PATH for the whole environment, causing surprises. This solution is much more transparent and perfectly suitable for running contained installations of wayland/wlroots/sway. The code unsetting the LD_LIBRARY_PATH/LD_PRELOAD was also deleted as it's a placebo security at best - we should trust the execution path that leads us to running sway, and it's way too late to care about those variables since we already started executing our compositor, thus we would be compromised anyway.
