2023-10-19openrc-pam: Use the entire PAM environmentNaomi Calabretta
Using whatever is left by the root user causes some login shells (such as Zsh on Artix Linux) to only load `/etc/profile{.d/*}` and not the user-defined `~/.profile`. This is not ideal as we rely on the user to tell us where some paths, such as `$XDG_CONFIG_PATH` and `$XDG_CACHE_PATH`, are. Signed-off-by: Anna (navi) Figueiredo Gomes <navi@vlhl.dev>

2023-10-19openrc-pam: allow to define runlevels by the argumentsAnna (navi) Figueiredo Gomes
this allows system administrators to define which runlevels to use, could permit them for example, to include the module in another pam file to customize when user scripts are auto-started, for example, allowing users to define a 'remote' runlevel that would be executed in a ssh login Signed-off-by: Anna (navi) Figueiredo Gomes <navi@vlhl.dev>

2023-10-19openrc: rework pathing functionsAnna (navi) Figueiredo Gomes
this simplifies the allocation of path string. also fixes some memory leaks from the ealier commit also changes the log path for users to XDG_CACHE_HOME, default ~/.cache/openrc Signed-off-by: Anna (navi) Figueiredo Gomes <navi@vlhl.dev>
2023-10-19openrc: create lockfile for --user.Anna (navi) Figueiredo Gomes
the pam module sets a variable that when in user mode, openrc should pick up and either create/increment, or decrement. this is done so that multiple session_open and session_close from pam doesn't randomly change the user runlevel for the current user. only the first session open starts the default runlevel, and only the last session close switches to the none runlevel.

2023-10-19openrc-pam: introduction of a PAM module for --userAnna (navi) Figueiredo Gomes
the module gets the pam user and executes a new login shell, in order to load the user's environment. this requires that the user's login shell supports `-c` as an option to run a command. all shells that i know of do. Signed-off-by: Anna (navi) Figueiredo Gomes <navi@vlhl.dev>

2023-10-19librc: Move sysconf dir to ~/.config/openrc/...Anna (navi) Figueiredo Gomes
Also add ~/.local/share/openrc for data files (like logs) This is done to help avoid name conflictions for anything else that might create/user files in .config/ Signed-off-by: Anna (navi) Figueiredo Gomes <navi@vlhl.dev>
2023-10-19librc: Allow user to override system-wide rc.confAnna (navi) Figueiredo Gomes
This change read a user version of rc.conf, to be located in `~/.config/rc.conf`. The user version is loaded first, so it has priority, thus overriding the system settings. Signed-off-by: Anna (navi) Figueiredo Gomes <navi@vlhl.dev>
2023-10-19librc: Use getpwuid instead of ${HOME} to get user's home directory.Anna (navi) Figueiredo Gomes
Using ${HOME} works when the user runs any librc program from the shell, but trying to invoke them from pam or similar, the variable is not set. Signed-off-by: Anna (navi) Figueiredo Gomes <navi@vlhl.dev>
2023-10-19openrc: Add support for user services.Anna (navi) Figueiredo Gomes
Modifies many functions where filesystem paths were hardcoded. In non-user-services mode, they still are. In user-services mode, they are allocated, since XDG_ dirs are to be set via environment variables. Signed-off-by: Anna (navi) Figueiredo Gomes <navi@vlhl.dev>

2023-10-03Relocate pipes.c and pipes.h file to shared directory.Lexxy Fox
With the addition of logger process redirect in supervise-daemon, pipes.c and pipes.h are now included in both s-s-d and supervise-daemon. Thus it makes sense to move the source files to the src/shared dir.
2023-10-03supervise-daemon: implement output_logger and error_logger.Lexxy Fox
Allows redirecting process stdin and stdout to another process, just like is already possible with start-stop-daemon. Also added --stdout-logger and --stderr-logger to the man page.
2023-09-12misc: add syscall fallback for close_range for musl libcNatanael Copa
Add fallback for the close_range syscall wrapper. This is needed for musl libc, which currently does not have a close_range wrapper. Also set errno on errors.
2023-09-12start-stop-daemon: set fds to CLOEXEC instead of closingNatanael Copa
Set file descriptors to CLOEXEC instead of closing them before exec, similar to what we do in supervise-daemon. Use the share cloexec_fds_from() helper for this. closefrom() is no longer used so remove the test.
2023-09-12misc: add cloexec_fds_from() helper functionNatanael Copa
Move logic to set file descriptors to a cloexec_fds_from() function in misc.c so it can be shared by both supervisor-daemon and start-stop-daemon, and hide the details behind.
2023-09-12supervise-daemon: rename HAVE_CLOSE_RANGE_EXEC to HAVE_CLOSE_RANGENatanael Copa
Use HAVE_CLOSE_RANGE to tell if system provides a close_range(2) wrapper, which better explains the purpose. Add a compat inline which returns -1 if close_range is unavailable.
2023-08-29Don't re-define strlcpy/strlcat with >=glibc-2.38Sam James
`>=glibc-2.38` implements strlcpy, strlcat, etc so check for those functions with Meson and don't provide conflicting prototypes. Technically, it doesn't need _GNU_SOURCE, but it's easier because it's not clear right now what glibc wants to guard it with. Note that these are in POSIX next anyway.

2023-07-26rc: fix automatic restart with runlevel-specific conf.d filesSven Wegener
Commit fc4f15d6cd8e7884f7094e5d3749b01f2d5a448f broke the automatic restart of services having runlevel-specific conf.d files. The double dirname() was not a mistake, but the way of getting from the service script in init.d to the upper directory containing the conf.d directory. dirname() modifies the argument in-place, so the second call operated on a modified value. To make it more obvious what is going on, have the second call operate on the returned value from the first call.

2023-05-10librc: allow overriding rc_interactive on kernel command lineSam James
This was originally introduced in 14625346c07a2a66fe77ce578c9423918bec1d97 with an example list (just one for rc_parallel) of options. Let's add in rc_interactive as it's a pretty obvious thing one might want to override. See https://forums.gentoo.org/viewtopic-p-8694588.html.
2023-04-24openrc-run: fix rc_parallel race in svc_execDominique Martinet
svc_exec waits until SIGCHLD comes in to close its input, but in rc_parallel case the SIGCHLD might be unrelated. Checking the proper pid is found in signal handler and only signaling signal_pipe the status code directly avoids this problem.

2023-04-24openrc-run: remove kludge in restart --no-depsDominique Martinet
restarting a service with --no-deps ran into a "hairy workaround", which had a few problems discussed in [1]: - it ignores --dry-run, really restarting the requested service - if the service was stopped, the program is started but the service status stays stopped. This makes long-lived services impossible to (re)start again (pid already exists and running), and the service also won't stop on shutdown. The kludge had a long comment describing the following situation: - openvpn needs net and dns - net restarts dns - dns needs net If the restart in net handled deps, openrc would deadlock waiting for net in dns' restart, as net won't be started until that is done. Restarting with --nodeps works around the deadlock, but can display errors without the kludge (note that the services did start properly anyway, the problem is that the default service path tries to lock dns twice from openvn's dep's start and net's start's restart): --- alpine:~# rc-service openvn start openvn | * Caching service dependencies ... [ ok ] net |net starting net |dns | * Call to flock failed: Resource temporarily unavailable net |dns | * ERROR: dns stopped by something else net |net started dns |dns started openvn |openvn started alpine:~# rc-status | grep s[1-3] net [ started ] dns [ started ] openvn [ started ] --- Locking again in restart --nodep can fail in two patterns: - openvpn's need dependency start was first, and the restart in net failed (case above): we can just silence locking failures and exit quietly with restart --no-deps, which is not worse than trying to restart while another process hold the lock. - the restart in net's start was first, and openvpn's need dependency start failed: not much can be done here short of adding a new status that a no-deps restart is in progress as in the comment, but this case can actually just be solved by adjusting dependencies -- and it actually has already been fixed: the current openvpn init script in alpine only 'use dns', so it will not try to start it, and that will start just fine with openvpn -> net -> dns only each starting each other once sequentially. Another failure pattern is just starting dns directly: that will start net, which will try to restart dns while we are starting it. Silencing messages on restart also solves this.

2023-04-24rc: use LIST_FOREACH_SAFE in cleanup()NRK
according to the linux manpage, the "safe" variant may not be available on all platform. however we bundle our own `queue.h` so this should not be an issue.
2023-04-24rc: block SIGCHLD during pid list operationsNRK
the pid list will be accessed inside the SIGCHLD signal handler. so we must ensure SIGCHLD handler doesn't get invoked while the list is at an inconsistent state making it unsafe to interact with.

2023-04-24rc: avoid calling free inside SIGCHLD handlerNRK
`free` is not async-signal-safe and calling it inside a signal handler can have bad effects, as reported in the musl ML: https://www.openwall.com/lists/musl/2023/01/23/1 the solution: - keep track of weather remove_pid() is being called from inside a signal handler or not. - if it's inside a signal handler then DO NOT call free - instead put that pointer into a "to be freed later" list. - if it's not inside a signal handler then take the "to be freed later" list and free anything in it.

2023-04-24fstabinfo: replace vfork with posix_spawnpNRK
problem: * vfork has been removed from POSIX [0]. * clang-tidy flags the `strerror` and `eerror` call inside the vfork-ed child as undefined behavior. solution: use posix_spawnp, which is serves similar purpose and is specified in posix. and as an added bonus, it's also easier to use and less lines of code.
