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: use right cast macros for UIDs, GIDs and PIDs

util-lib: split out allocation calls into alloc-util.[ch]

util-lib: move more locale-related calls to locale-util.[ch]

util-lib: move string table stuff into its own string-table.[ch]

util-lib: split out user/group/uid/gid calls into user-util.[ch]

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.

sd-bus: fix error handling of pthread API calls pthread APIs (unlike the rest of libc) return their errors as positive error codes directly from the functions, rather than using errno. Let's make sure we always handle things that way.

tree-wide: introduce mfree() Pretty trivial helper which wraps free() but returns NULL, so we can simplify this: free(foobar); foobar = NULL; to this: foobar = mfree(foobar);

bus-proxy: ignore 'log' attributes in XML policy 'log' is unsupported but nothing to warn about. Ignore it just like we ignore 'eavesdrop'.

shared: add formats-util.h

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.

Assorted format fixes Types used for pids and uids in various interfaces are unpredictable. Too bad.

bus-proxy: don't print error-messages if we check multiple dests If we test the policy against multiple destination names, we really should not print warnings if one of the names results in DENY. Instead, pass the whole array of names to the policy and let it deal with it.

bus-proxy: implement org.freedesktop.DBus.ReloadConfig() Make sure to reload our xml policy configuration if requested via the bus.

bus-proxy: share policy between threads This implements a shared policy cache with read-write locks. We no longer parse the XML policy in each thread. This will allow us to easily implement ReloadConfig().

bus-proxy: implement 'at_console' The 'at_console' policy-category allows to apply policy-items to clients depending on whether they're run from within a valid user-session or not. We use sd_uid_get_seats() to check whether a user has a valid seat (which excludes remote-sessions like ssh).

bus-proxy: print message direction in policy logs Make sure to print "dbus-1 to kernel" or "kernel to dbus-1" in policy logs to better diagnose the situation.

bus-proxy: fix swapped path/interface debug messages The policy debug messages swapped "path=" and "interface=", fix this.

bus-proxy-test: show parsed system/session policy

bus-proxy: eat up "*" matches, they are pointless

bus-proxyd: xml - consider empty tags as recv

bus-proxy: make sure sure eavesdrop= XML attributes are properly handled

tree-wide: spelling fixes https://github.com/vlajos/misspell_fixer https://github.com/torstehu/systemd/commit/b6fdeb618cf2f3ce1645b3315f15f482710c7ffa Thanks to Torstein Husebo <torstein@huseboe.net>.

core: rearrange code so that libsystemd/sd-bus/ does not include header files from core Stuff in src/shared or src/libsystemd should *never* include code from src/core or any of the tools, so don't do that here either. It's not OK!
