* tree-wide: use "hostname" spelling everywhereZbigniew Jędrzejewski-Szmek2020-04-211-1/+1
| | | | | | | | It's not that I think that "hostname" is vastly superior to "host name". Quite the opposite — the difference is small, and in some context the two-word version does fit better. But in the tree, there are ~200 occurrences of the first, and >1600 of the other, and consistent spelling is more important than any particular spelling choice.
* man: move "myhostname" right after "resolve"Zbigniew Jędrzejewski-Szmek2020-04-161-1/+1
| | | | | | | | | The text in the man page provides the justification why I think this is generally the right thing. An additional reason is that with the previous commit (to move resolved earlier), since resolved internally implements the same rules that nss-myhostname does, we'd have this strange inversion where the priority of external configuration would be different in the "resolve" path and in the fallback path.
* man: move "files" after "resolve" in the suggested configurationZbigniew Jędrzejewski-Szmek2020-04-161-9/+10
| | | | | | | | | resolved caches files, so we should move nss-files after nss-resolve to speed up local access (and yes, people like to have thousands of lines in /etc/hosts). See https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/message/LCX6YXLM62QEYJSOLJBWXXVXTZVL73GI/ for the background.
* man: use same header for all filesZbigniew Jędrzejewski-Szmek2019-03-141-1/+1
| | | | | | | The "include" files had type "book" for some raeason. I don't think this is meaningful. Let's just use the same everywhere. $ perl -i -0pe 's^..DOCTYPE (book|refentry) PUBLIC "-//OASIS//DTD DocBook XML V4.[25]//EN"\s+"http^<!DOCTYPE refentry PUBLIC "-//OASIS//DTD DocBook XML V4.5//EN"\n "http^gms' man/*.xml
* man: standarize on one-line license headerZbigniew Jędrzejewski-Szmek2019-03-141-4/+1
| | | | | | No need to waste space, and uniformity is good. $ perl -i -0pe 's|\n+<!--\s*SPDX-License-Identifier: LGPL-2.1..\s*-->|\n<!-- SPDX-License-Identifier: LGPL-2.1+ -->|gms' man/*.xml
* man,factory: update factory config for nsswitch.conf to match the man pagesZbigniew Jędrzejewski-Szmek2018-11-271-0/+1
| | | | | Also add a note in the man pages to remind people to adjust the factory config and other man pages at the same time.
* meson: allow building resolved and machined without nss modulesYu Watanabe2018-07-231-1/+1
| | | | | | | | | | | This adds -Dnss-resolve= and -Dnss-mymachines= meson options. By using this option, e.g., resolved can be built without nss-resolve. When no nss modules are built, then test-nss is neither built. Also, This changes the option name -Dmyhostname= to -Dnss-myhostname= for consistency to other nss related options. Closes #9596.
* man: drop mode line in file headersZbigniew Jędrzejewski-Szmek2018-07-031-1/+1
| | | | | This is already included in .dir-locals, so we don't need it in the files themselves.
* tree-wide: drop copyright headers from frequent contributorsZbigniew Jędrzejewski-Szmek2018-06-201-2/+0

* man: drop unused <authorgroup> tags from man sourcesZbigniew Jędrzejewski-Szmek2018-06-141-9/+0
| | | | | | | | | | | | Docbook styles required those to be present, even though the templates that we use did not show those names anywhere. But something changed semi-recently (I would suspect docbook templates, but there was only a minor version bump in recent years, and the changelog does not suggest anything related), and builds now work without those entries. Let's drop this dead weight. Tested with F26-F29, debian unstable. $ perl -i -0pe 's/\s*<authorgroup>.*<.authorgroup>//gms' man/*xml
* tree-wide: beautify remaining copyright statementsLennart Poettering2018-06-141-1/+1
| | | | | | Let's unify an beautify our remaining copyright statements, with a unicode ©. This means our copyright statements are now always formatted the same way. Yay.
* tree-wide: remove Lennart's copyright linesLennart Poettering2018-06-141-1/+0
| | | | | | | | | | | These lines are generally out-of-date, incomplete and unnecessary. With SPDX and git repository much more accurate and fine grained information about licensing and authorship is available, hence let's drop the per-file copyright notice. Of course, removing copyright lines of others is problematic, hence this commit only removes my own lines and leaves all others untouched. It might be nicer if sooner or later those could go away too, making git the only and accurate source of authorship information.
* tree-wide: drop 'This file is part of systemd' blurbLennart Poettering2018-06-141-2/+0
| | | | | | | | | | | | | | | | This part of the copyright blurb stems from the GPL use recommendations: https://www.gnu.org/licenses/gpl-howto.en.html The concept appears to originate in times where version control was per file, instead of per tree, and was a way to glue the files together. Ultimately, we nowadays don't live in that world anymore, and this information is entirely useless anyway, as people are very welcome to copy these files into any projects they like, and they shouldn't have to change bits that are part of our copyright header for that. hence, let's just get rid of this old cruft, and shorten our codebase a bit.
* tree-wide: drop license boilerplateZbigniew Jędrzejewski-Szmek2018-04-061-13/+0
| | | | | | | | | | Files which are installed as-is (any .service and other unit files, .conf files, .policy files, etc), are left as is. My assumption is that SPDX identifiers are not yet that well known, so it's better to retain the extended header to avoid any doubt. I also kept any copyright lines. We can probably remove them, but it'd nice to obtain explicit acks from all involved authors before doing that.
* Add SPDX license identifiers to man pagesZbigniew Jędrzejewski-Szmek2017-11-191-0/+2

* build-sys: s/ENABLE_RESOLVED/ENABLE_RESOLVE/Zbigniew Jędrzejewski-Szmek2017-10-041-1/+1
| | | | | | The configuration option was called -Dresolve, but the internal define was …RESOLVED. This options governs more than just resolved itself, so let's settle on the version without "d".

* man: describe the relationship between nss-myhostname and nss-resolvedZbigniew Jędrzejewski-Szmek2017-06-291-2/+13

* man: sync up the suggested nsswitch.conf configuration for our four NSS modulesLennart Poettering2016-10-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | This unifies the suggested nsswitch.conf configuration for our four NSS modules to this: hosts: files mymachines resolve [!UNAVAIL=return] dns myhostname Note that this restores "myhostname" to the suggested configuration of nss-resolve for the time being, undoing 4484e1792b64b01614f04b7bde97bf019f601bf9. "myhostname" should probably be dropped eventually, but when we do this we should do it in full, and not only drop it from the suggested nsswitch.conf for one of the modules, but also drop it in source and stop referring to it altogether. Note that nss-resolve doesn't replace nss-myhostname in full: the former only works if D-Bus/resolved is available for resolving the local hostname, the latter works in all cases even if D-Bus or resolved are not in operation, hence there's some value in keeping the line as it is right now. Note that neither dns nor myhostname are considered at all with the above configuration unless the resolve module actually returns UNAVAIL. Thus, even though handling of local hostname resolving is implemented twice this way it is only executed once for each lookup.
* nss-resolve: return NOTFOUND instead of UNAVAIL on resolution errorsMartin Pitt2016-10-011-1/+3
| | | | | | | | | | | | | | | | It needs to be possible to tell apart "the nss-resolve module does not exist" (which can happen when running foreign-architecture programs) from "the queried DNS name failed DNSSEC validation" or other errors. So return NOTFOUND for these cases too, and only keep UNAVAIL for the cases where we cannot handle the given address family. This makes it possible to configure a fallback to "dns" without breaking DNSSEC, with "resolve [!UNAVAIL=return] dns". Add this to the manpage. This does not change behaviour if resolved is not running, as that already falls back to the "dns" glibc module. Fixes #4157
* man: drop myhostname from recommended nsswitch host configurationMartin Pitt2016-10-011-1/+1
| | | | resolve includes myhostname functionality, so there is no need to add it again.
* nss: add new "nss-systemd" NSS module for mapping dynamic usersLennart Poettering2016-07-221-3/+4
| | | | | With this NSS module all dynamic service users will be resolvable via NSS like any real user.
* man: change recommended order of NSS modules in /etc/nsswitch.confLennart Poettering2016-02-231-26/+19
| | | | | | | | | | | | | | So far we recommended placing "nss-mymachines" after "nss-resolve" in the order of preference in /etc/nsswitch.conf. This change reverse this order. Rationale: single-label names are resolved via LLMNR by resolved, which has to time out if no peer by that name exists. By placing "nss-mymachines" first (which always responds immediately) we avoid running into this timeout for most containers. Both modules should return the same data if LLMNR is used by the container anyway. While we are at it, improve the man pages of the three NSS modules in other ways a bit.

* man: always use the same example in nss module documentationLennart Poettering2015-09-041-2/+2
| | | | | | | | Show the same recommended example file in all three man pages, just highlight the different, relevant parts. This should be less confusing for users, and clarify what we actually recommend how /etc/nsswitch.conf is set up.
