Prep 229.9: Make all supportable API functions visible. The process of cleaning up elogind, meaning to mask all bits that are unneeded by elogind, has been finished a while ago. It is therefore time to re-enable all previously masked API functions that elogind can support. This will make it easier for future developers to integrate elogind into their software where they already support systemd-login.
sd-login: translate -ENOMEDIUM to -ENODATA The -ENOMEDIUM return value was introduced in v232-1001-g2977724b09, ('core: make hybrid cgroup unified mode keep compat /sys/fs/cgroup/elogind hierarchy'), and would be returned by cg_pid_get_path_shifted(), but the documented and expected return value is -ENODATA. Let's just catch ENXIO/ENOMEDIUM and translate it to ENODATA in all cases. Complements 171f8f591ff27ebb5ff475b7a9d1f13a846c9331, fixes #6012.
test-login: make the test non-manual test-login.c is largely rewritten to use _cleanup_ and give more meaningful messages (function names are used instead of creative terms like "active session", so that when something unexpected is returned, it's much easier to see what function is responsible). The monitoring part is only activated if '-m' is passed on the command line. It runs against the information from /run/elogind/ in the live system, but that should be OK: logind/sd-login interface is supposed to be stable and both backwards and forwards compatible. If not running in a login session, some tests are skipped. Those two changes together mean that it's possible to run test-login in the test suite. Tests for sd_pid_get_{unit,user_unit,slice} are added.
Prep v233.3: Add missing documentation for API functions exported by elogind. (unreviewed)
Major cleanup of all leftovers after rebasing on The patching of elogind in several steps with only partly rebasing on a common commit with upstream, left the tree in a state, that was unmergeable with master. By rebasing on master and manually cleaning up all commits, this merge is now possible. However, this process left some orphans, that are cleanup now.
man: revert dynamic paths for split-usr setups This did not really work out as we had hoped. Trying to do this upstream introduced several problems that probably makes it better suited as a downstream patch after all. At any rate, it is not releaseable in the current state, so we at least need to revert this before the release. * by adjusting the path to binaries, but not do the same thing to the search path we end up with inconsistent man-pages. Adjusting the search path too would be quite messy, and it is not at all obvious that this is worth the effort, but at any rate it would have to be done before we could ship this. * this means that distributed man-pages does not make sense as they depend on config options, and for better or worse we are still distributing man pages, so that is something that definitely needs sorting out before we could ship with this patch. * we have long held that split-usr is only minimally supported in order to boot, and something we hope will eventually go away. So before we start adding even more magic/effort in order to make this work nicely, we should probably question if it makes sense at all.
man: generate configured paths in manpages In particular, use /lib/systemd instead of /usr/lib/systemd in distributions like Debian which still have not adopted a /usr merge setup. Use XML entities from man/custom-entities.ent to replace configured paths while doing XSLT processing of the original XML files. There was precedent of some files (such as systemd.generator.xml) which were already using this approach. This addresses most of the (manual) fixes from this patch: http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/patches/Fix-paths-in-man-pages.patch?h=experimental-220 The idea of using generic XML entities was presented here: http://lists.freedesktop.org/archives/systemd-devel/2015-May/032240.html This patch solves almost all the issues, with the exception of: - Path to /bin/mount and /bin/umount. - Generic statements about preference of /lib over /etc. These will be handled separately by follow up patches. Tested: - With default configure settings, ran "make install" to two separate directories and compared the output to confirm they matched exactly. - Used a set of configure flags including $CONFFLAGS from Debian: http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/rules Installed the tree and confirmed the paths use /lib/systemd instead of /usr/lib/systemd and that no other unexpected differences exist. - Confirmed that `make distcheck` still passes.

man: add a mapping for external manpages It is annoying when we have dead links on fd.o. Add project='man-pages|die-net|archlinux' to <citerefentry>-ies. In generated html, add external links to http://man7.org/linux/man-pages/man, http://linux.die.net/man/, https://www.archlinux.org/. By default, pages in sections 2 and 4 go to man7, since Michael Kerrisk is the autorative source on kernel related stuff. The rest of links goes to linux.die.net, because they have the manpages. Except for the pacman stuff, since it seems to be only available from archlinux.org. Poor gummiboot gets no link, because gummitboot(8) ain't to be found on the net. According to common wisdom, that would mean that it does not exist. But I have seen Kay using it, so I know it does, and deserves to be found. Can somebody be nice and put it up somewhere?
doc: balance C indirections in function prototypes Shift the asterisks in the documentation's prototypes such that they are consistent among each other. Use the right side to match what is used in source code. Addendum to commit v209~82.
sd-login: add calls that retrieve credentials of peers connected to AF_UNIX peers This is supposed to be an extension of SO_PEERCRED and SO_PEERSEC, except for cgroup information.
man: fix references to .pc files which aren't separate anymore
man: resolve word omissions This is a recurring submission and includes corrections to: word omissions and word class choice.
man: wording and grammar updates This is a recurring submission and includes corrections to various issue spotted. I guess I can just skip over reporting ubiquitous comma placement fixes… Highligts in this particular commit: - the "unsigned" type qualifier is completed to form a full type "unsigned int" - alphabetic -> lexicographic (that way we automatically define how numbers get sorted)
