tree-wide: remove Emacs lines from all files This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.

tree-wide: sort includes Sort the includes accoding to the new coding style.

util-lib: split our string related calls from util.[ch] into its own file string-util.[ch] There are more than enough calls doing string manipulations to deserve its own files, hence do something about it. This patch also sorts the #include blocks of all files that needed to be updated, according to the sorting suggestions from CODING_STYLE. Since pretty much every file needs our string manipulation functions this effectively means that most files have sorted #include blocks now. Also touches a few unrelated include files.

basic: rework virtualization detection API Introduce a proper enum, and don't pass around string ids anymore. This simplifies things quite a bit, and makes virtualization detection more similar to architecture detection.

remove unused includes This patch removes includes that are not used. The removals were found with include-what-you-use which checks if any of the symbols from a header is in use.

treewide: no need to negate errno for log_*_errno() It corrrectly handles both positive and negative errno values.

treewide: auto-convert the simple cases to log_*_errno() As a followup to 086891e5c1 "log: add an "error" parameter to all low-level logging calls and intrdouce log_error_errno() as log calls that take error numbers", use sed to convert the simple cases to use the new macros: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\("(.*)%s"(.*), strerror\(-([a-zA-Z_]+)\)\);/log_\1_errno(-\4, "\2%m"\3);/' Multi-line log_*() invocations are not covered. And we also should add log_unit_*_errno().

localectl: print warning when there are options given on kernel cmdline

Introduce strv_consume which takes ownership This mirrors set_consume and makes the common use a bit nicer.

local: fix memory leak when putting together locale settings Also, we need to use proper strv_env_xyz() calls when putting together the environment array, since otherwise settings won't be properly overriden. And let's get rid of strv_appendf(), is overkill and there was only one user.

rework systemd's own process environment handling/passing Stop importing non-sensical kernel-exported variables. All parameters in the kernel command line are exported to the initial environment of PID1, but suppressed if they are recognized by kernel built-in code. The EFI booted kernel will add further kernel-internal things which do not belong into userspace. The passed original environ data of the process is not touched and preserved across re-execution, to allow external reading of /proc/self/environ for process properties like container*=.

Do not set LANG=C in every child environment. LANG does not have to be set and setting it to default to the default does not add any value.

Use initalization instead of explicit zeroing Before, we would initialize many fields twice: first by filling the structure with zeros, and then a second time with the real values. We can let the compiler do the job for us, avoiding one copy. A downside of this patch is that text gets slightly bigger. This is because all zero() calls are effectively inlined: $ size build/.libs/systemd text data bss dec hex filename before 897737 107300 2560 1007597 f5fed build/.libs/systemd after 897873 107300 2560 1007733 f6075 build/.libs/systemd … actually less than 1‰. A few asserts that the parameter is not null had to be removed. I don't think this changes much, because first, it is quite unlikely for the assert to fail, and second, an immediate SEGV is almost as good as an assert.

honor SELinux labels, when creating and writing config files Also split out some fileio functions to fileio.c and provide a SELinux aware pendant in fileio-label.c see https://bugzilla.redhat.com/show_bug.cgi?id=881577

core: drop support for old per-distro configuration files for console, hostname, locale, timezone This simplifies the upstream system code quite a bit. If downstream distributions want to maintain compatibility with their old configuration files, they are welcome to do so, but need to maintain this as patches downstream. The burden needs to be on the distributions to maintain differences here. Our suggestion however is to just convert the old configuration files on upgrade, as multiple distributions already do.

build-sys: drop TARGET_UBUNTU TARGET_UBUNTU is effectively the same as TARGET_DEBIAN. Given the Ubuntu is unlikely to use systemd anytime soon there's no point in keeping this separate.

locale: modernizations

drop Arch Linux support for reading /etc/rc.conf

remove Fedora hostname, locale, vconsole legacy file support

MeeGo: Remove build support for MeeGo distribution. The MeeGo distribution is still a supported distribution, but will probably not see an updated version of systemd anymore. Most of the development is focussing on Tizen now, and the generic support for building --with-distro=other is more than adequate enough. This patch removes the support as a custom configuration build target in systemd. People who are still building this for the MeeGo distribution should build as "other" distro.

relicense to LGPLv2.1 (with exceptions) We finally got the OK from all contributors with non-trivial commits to relicense systemd from GPL2+ to LGPL2.1+. Some udev bits continue to be GPL2+ for now, but we are looking into relicensing them too, to allow free copy/paste of all code within systemd. The bits that used to be MIT continue to be MIT. The big benefit of the relicensing is that closed source code may now link against libsystemd-login.so and friends.

move libsystemd_core.la sources into core/
