2017-02-17copy: change the various copy_xyz() calls to take a unified flags parameterLennart Poettering
This adds a unified "copy_flags" parameter to all copy_xyz() function calls, replacing the various boolean flags so far used. This should make many invocations more readable as it is clear what behaviour is precisely requested. This also prepares ground for adding support for more modes later on.
2016-11-07Rename formats-util.h to format-util.hZbigniew Jędrzejewski-Szmek
We don't have plural in the name of any other -util files and this inconsistency trips me up every time I try to type this file name from memory. "formats-util" is even hard to pronounce.

2016-07-22sysusers: move various user credential validity checks to src/basic/Lennart Poettering
This way we can reuse them for validating User=/Group= settings in unit files (to be added in a later commit). Also, add some tests for them.

2016-01-13tree-wide: check if errno is greater then zeroZbigniew Jędrzejewski-Szmek
gcc is confused by the common idiom of return errno ? -errno : -ESOMETHING and thinks a positive value may be returned. Replace this condition with errno > 0 to help gcc and avoid many spurious warnings. I filed a gcc rfe a long time ago, but it hard to say if it will ever be implemented [1]. Both conventions were used in the codebase, this change makes things more consistent. This is a follow up to bcb161b0230f. [1] https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61846
2015-11-10defs: rework CONF_DIRS_NULSTR() macroLennart Poettering
The macro is generically useful for putting together search paths, hence let's make it truly generic, by dropping the implicit ".d" appending it does, and leave that to the caller. Also rename it from CONF_DIRS_NULSTR() to CONF_PATHS_NULSTR(), since it's not strictly about dirs that way, but any kind of file system path. Also, mark CONF_DIR_SPLIT_USR() as internal macro by renaming it to _CONF_PATHS_SPLIT_USR() so that the leading underscore indicates that it's internal.

2015-11-03util-lib: move CONF_DIRS_NULSTR definition to def.hLennart Poettering
After all, this is not some compiler or C magic, but something very specific to how systemd works, hence let's move it into def.h, and out of macro.h

2015-10-27util-lib: move take_password_lock() to user-util.[ch]Lennart Poettering
Also, rename it take_etc_passwd_lock(), in order to make it more expressive.

2015-10-25util-lib: split out fd-related operations into fd-util.[ch]Lennart Poettering
There are more than enough to deserve their own .c file, hence move them over.
2015-10-24util-lib: split our string related calls from util.[ch] into its own file ↵Lennart Poettering
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.
2015-10-24path-util: unify how we process paths specified on the command lineLennart Poettering
Let's introduce a common function that makes relative paths absolute and warns about any errors while doing so.
2015-10-24util-lib: get_current_dir_name() can return errors other than ENOMEMLennart Poettering
get_current_dir_name() can return a variety of errors, not just ENOMEM, hence don't blindly turn its errors to ENOMEM, but return correct errors in path_make_absolute_cwd(). This trickles down into a couple of other functions, some of which receive unrelated minor fixes too with this commit.
2015-10-07smack: label /etc/passwd and friends as '_' smack label when ↵Sangjung Woo
--with-smack-run-label' is enabled systemd-sysusers.service unit creates system users and groups and it could update /etc/passwd, /etc/group, /etc/shadow and /etc/gshadow. Those files should have '_' smack label because of accessibility. However, if systemd has its own smack label using '--with-smack-run-label' configuration, systemd-sysusers process spawned by systemd(pid:1) has its parent smack label and eventually updated files also is set as its parent smack label. This patch fixes that bug by labeling updated files as '_' smack label when --with-smack-run-label' is enabled.
2015-09-29util: introduce common version() implementation and use it everywhereLennart Poettering
This also allows us to drop build.h from a ton of files, hence do so. Since we touched the #includes of those files, let's order them properly according to CODING_STYLE.

Creating group input with gid 491. Failed to write files: File exists "Why is the presence of /etc/group a problem?"
2015-09-10tree-wide: never use the off_t unless glibc makes us use itLennart Poettering
off_t is a really weird type as it is usually 64bit these days (at least in sane programs), but could theoretically be 32bit. We don't support off_t as 32bit builds though, but still constantly deal with safely converting from off_t to other types and back for no point. Hence, never use the type anymore. Always use uint64_t instead. This has various benefits, including that we can expose these values directly as D-Bus properties, and also that the values parse the same in all cases.
2015-08-07util: Don't interpret quotes by default in extract_first_wordRichard Maw
This adds an EXTRACT_QUOTES option to allow the previous behaviour, of not interpreting any character inside ' or " quotes as separators.
2015-08-07util: change unquote_*_word to extract_*_wordRichard Maw
It now takes a separators argument, which defaults to WHITESPACE if NULL is passed.
2015-08-07Convert unquote_*_word users to expect isempty(p) after the last entryRichard Maw
This is so that, when called in a loop, unquote_first_word can distinguish between reaching the end of a string because it has consumed all the input before the end, and consuming all the input. This is important because we later add a flag that allows char *in = ""; char *out; unquote_first_word(&in, &out, flags); To put "" in out, and set in = NULL, so the trailing empty string of the input can be consumed, and mark that the input has been consumed.
2015-07-31tree-wide: introduce mfree()David Herrmann
Pretty trivial helper which wraps free() but returns NULL, so we can simplify this: free(foobar); foobar = NULL; to this: foobar = mfree(foobar);
2015-07-30tree-wide: use free_and_strdup()Daniel Mack
Use free_and_strdup() where appropriate and replace equivalent, open-coded versions.
2015-05-13util: add generic calls for prefixing a root directory to a pathLennart Poettering
So far a number of utilities implemented their own calls for this, unify them in prefix_root() and prefix_roota(). The former uses heap memory, the latter allocates from the stack via alloca(). Port over most users of a --root= logic.
2015-04-10shared: add formats-util.hRonny Chevalier
2015-03-26util: rework word parsing and c unescaping codeLennart Poettering
When parsing words from input files, optionally automatically unescape the passed strings, controllable via a new flags parameter. Make use of this in tmpfiles, and port everything else over, too. This improves parsing quite a bit, since we no longer have to process the same string multiple times with different calls, where an earlier call might corrupt the input for a later call.
2015-03-07sysusers: do not reject users with already present /etc/shadow entriesIvan Shapovalov
This is needed to interoperate firstboot and sysusers. The former one is started first, and it writes only /etc/shadow when it is told to set the root password. It's better to relax checks here than to duplicate functionality in firstboot.
2015-02-23remove unused includesThomas Hindoe Paaboel Andersen
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.
2015-02-03util: rework strappenda(), and rename it strjoina()Lennart Poettering
After all it is now much more like strjoin() than strappend(). At the same time, add support for NULL sentinels, even if they are normally not necessary.

2014-11-28treewide: another round of simplificationsMichal Schmidt
Using the same scripts as in f647962d64e "treewide: yet more log_*_errno + return simplifications".
2014-11-28treewide: use log_*_errno whenever %m is in the format stringMichal Schmidt
If the format string contains %m, clearly errno must have a meaningful value, so we might as well use log_*_errno to have ERRNO= logged. Using: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\((".*%m.*")/log_\1_errno(errno, \2/' Plus some whitespace, linewrap, and indent adjustments.
2014-11-28treewide: a few more log_*_errno + return simplificationsMichal Schmidt
The one in tmpfiles.c:create_item() even looks like it fixes a bug.
2014-11-28treewide: yet more log_*_errno + return simplificationsMichal Schmidt
Using: find . -name '*.[ch]' | while read f; do perl -i.mmm -e \ 'local $/; local $_=<>; s/(if\s*\([^\n]+\))\s*{\n(\s*)(log_[a-z_]*_errno\(\s*([->a-zA-Z_]+)\s*,[^;]+);\s*return\s+\g4;\s+}/\1\n\2return \3;/msg; print;' $f done And a couple of manual whitespace fixups.
2014-11-28treewide: no need to negate errno for log_*_errno()Michal Schmidt
It corrrectly handles both positive and negative errno values.
2014-11-28treewide: auto-convert the simple cases to log_*_errno()Michal Schmidt
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().
2014-11-26Introduce CONF_DIRS_NULSTR helper to define standard conf dirsJosh Triplett
Several different systemd tools define a nulstr containing a standard series of configuration file directories, in /etc, /run, /usr/local/lib, /usr/lib, and (#ifdef HAVE_SPLIT_USR) /lib. Factor that logic out into a new helper macro, CONF_DIRS_NULSTR.

2014-10-30sysusers: Preserve ownership and mode on /etc/passwd and friendsColin Guthrie
When running sysusers we would clobber file ownership and permissions on the files /etc/passwd, /etc/group and /etc/[g]shadow. This simply preserves the ownership and mode if existing files are found.
