server_configure_done is the code we ran in IMSG_RECONF_END splitted
in a separate functions.
This is all needed for ge.c which doesn't do privsep but needs to
bootstrap the server process.
it's better than the previous Makefile.depend approach since this
automatically adapts to the included headers without requiring
manual intervention to regen the list.
It uses the 'common' proc.c from various OpenBSD-daemons.
gmid grew organically bit by bit and it was also the first place where I
tried to implement privsep. It wasn't done very well, in fact the
parent process (that retains root privileges) just fork()s a generation
of servers, all sharing *exactly* the same address space. No good!
Now, we fork() and re-exec() ourselves, so that each process has a fresh
address space.
Some features (require client ca for example) are temporarly disabled,
will be fixed in subsequent commits. The "ge" program is also
temporarly disabled as it needs tweaks to do privsep too.
it reached a point where this stuff is not maintenable. I'd like
to move forward with gmid, but the restriction of capsicum and the
linux environment at large that make landlock unusable (how can you
resolve DNS portably when under landlock?) -and don't get me started
on seccomp- makes it impossible for me to do any work.
So, I prefer removing the crap, resuming working on gmid by cleaning
stuff and consolidating the features, improving various things
etc... and then eventually see how to introduce some sandboxing
again on other systems. Patches to resume sandboxing are, as always,
welcome!
it’s the QUERY_STRING decoded if it’s a search-string (i.e. not a
key-value pair.) It’s useful for scripts to avoid percent-decoding
the querystring in the most common case of a query, because in Gemini
querystrings key-value paired are not common.
Idea from a discussion with Allen Sobot.
