journal: add minimal journal gateway daemon based on GNU libmicrohttpd This minimal HTTP server can serve journal data via HTTP. Its primary purpose is synchronization of journal data across the network. It serves journal data in three formats: text/plain: the text format known from /var/log/messages application/json: the journal entries formatted as JSON application/vnd.fdo.journal: the binary export format of the journal The HTTP server also serves a small HTML5 app that makes use of the JSON serialization to present the journal data to the user. Examples: This downloads the journal in text format: # systemctl start systemd-journal-gatewayd.service # wget http://localhost:19531/entries Same for JSON: # curl -H"Accept: application/json" http://localhost:19531/entries Access via web browser: $ firefox http://localhost:19531/ 2012-09-28 02:46:32 +04:00			`# This file is part of systemd.`

units,sysusers: use DynamicUser= for journal-gatewayd and drop user systemd-journal-gateway from sysusers 2017-07-28 06:28:17 +03:00			`DynamicUser=yes`
core: enable PrivateNetwork= for a number of our long running services where this is useful 2014-03-20 02:08:39 +04:00			`PrivateDevices=yes`
			`PrivateNetwork=yes`
core: rename ReadOnlySystem= to ProtectSystem= and add a third value for also mounting /etc read-only Also, rename ProtectedHome= to ProtectHome=, to simplify things a bit. With this in place we now have two neat options ProtectSystem= and ProtectHome= for protecting the OS itself (and optionally its configuration), and for protecting the user's data. 2014-06-04 20:07:55 +04:00			`ProtectHome=yes`
units: further lock down our long-running services Let's make this an excercise in dogfooding: let's turn on more security features for all our long-running services. Specifically: - Turn on RestrictRealtime=yes for all of them - Turn on ProtectKernelTunables=yes and ProtectControlGroups=yes for most of them - Turn on RestrictAddressFamilies= for all of them, but different sets of address families for each Also, always order settings in the unit files, that the various sandboxing features are close together. Add a couple of missing, older settings for a numbre of unit files. Note that this change turns off AF_INET/AF_INET6 from udevd, thus effectively turning of networking from udev rule commands. Since this might break stuff (that is already broken I'd argue) this is documented in NEWS. 2016-08-26 14:23:27 +03:00			`ProtectControlGroups=yes`

units: restrict namespace for a good number of our own services Basically, we turn it on for most long-running services, with the exception of machined (whose child processes need to join containers here and there), and importd (which sandboxes tar in a CLONE_NEWNET namespace). machined is left unrestricted, and importd is restricted to use only "net" 2017-02-09 12:28:23 +03:00			`RestrictNamespaces=yes`

journal: bump RLIMIT_NOFILE when journal files to 16K (if possible) When there are a lot of split out journal files, we might run out of fds quicker then we want. Hence: bump RLIMIT_NOFILE to 16K if possible. Do these even for journalctl. On Fedora the soft RLIMIT_NOFILE is at 1K, the hard at 4K by default for normal user processes, this code hence bumps this up for users to 4K. https://bugzilla.redhat.com/show_bug.cgi?id=1179980 2015-01-08 05:17:50 +03:00			`# If there are many split upjournal files we need a lot of fds to`
