mod_posix: Move everything to util.startup

Sat, 23 Mar 2024 20:48:19 +0100

mod_posix: Move everything to util.startup

This allows greater control over the order of events.

Notably, the internal ordering between daemonization, initialization of
libunbound and setup of signal handling is sensitive.

libunbound starts a separate thread for processing DNS requests.
If this thread is started before signal handling has been set up, it
will not inherit the signal handlers and instead behave as it would have
before signal handlers were set up, i.e. cause the whole process to
immediately exit.

libunbound is usually initialized on the first DNS request, usually
triggered by an outgoing s2s connection attempt.

If daemonization happens before signals have been set up, signals may
not be processed at all.

mod_posix: Move POSIX signal handling into util.startup to avoid race

mod_posix: Move POSIX signal handling into util.startup to avoid race

When libunbound is initialized, it spawns a thread to work in.
In case a module initializes libunbound, e.g. by triggering a s2s
connection, Prosody would not handle signals, instead immediately quit
on e.g. the reload (SIGHUP) signal. Likely because the libunbound thread
would not have inherited the signal mask from the main Prosody thread.

Thanks Menel, riau and franck-x for reporting and help narrowing down

mod_posix: Exit with non-zero status code on problems

Previously it would default to exit with 0 as status code, meaning
success, which is weird.

mod_posix: Daemonize later

Daemonizing later means we can use that as a "successful startup"
signal and problems can be reported via exit code.

mod_posix: Remove ancient undocumented user switching

Mon, 24 Aug 2020 19:48:47 +0200

mod_posix: Remove ancient undocumented user switching

User switching has been done by prosodyctl or init scripts for a very
long time now, so this is not needed.

Using this would not have worked with module reloading (e.g. to reload
certificates) since ports are closed and re-bound, which would then not
be allowed.

Today there exists better ways to grant low ports, i.e. capabilities(7)

Why do we have this?
Remove it

mod_posix: Delay setting signal handlers until in the main thread

Signal handlers work by setting a debug hook. Hooks are per-thread, so we need this to be called in the main thread. However module loading is not in the main thread anymore.
