2015-10-27util-lib: move more file I/O related calls into fileio.[ch]Lennart Poettering
2015-10-27util: remove path_get_parent(), in favour of dirname_malloc()Lennart Poettering
We don't need two functions that do essentialy the same, hence drop path_get_parent(), and stick to dirname_malloc(), but move it to path-util.[ch].

2015-10-26util-lib: split out IO related calls to io-util.[ch]Lennart Poettering
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.
2015-10-24util: split out escaping code into escape.[ch]Lennart Poettering
This really deserves its own file, given how much code this is now.
2015-10-24util: split out extract_first_word() and related calls into extract-word.[ch]Lennart Poettering
This is quite a lot of code these days, hence move it to its own source file.

btrfs quota beef up and various other unrelated changes
2015-10-22util: Replace state with separate booleans in extract_first_wordFilipe Brandenburger
This simplifies the logic and uniformizes the way single and double quotes are handled. In the end, the code is about 40 lines shorter. Tested by running the excellent test cases from test-util. Also installed the systemd binaries including this patch and booted a system with it, everything looked normal.
2015-10-22util: allow unbalanced double quote in EXTRACT_QUOTES|EXTRACT_RELAX modeEvgeny Vereshchagin
extract_first_word understands "\'string" but doesn't understand "\"string" fixed this inconsistency.
2015-10-22util: improve dir_is_empty() callLennart Poettering
Simplify the call, and add dir_is_populated() as inverse call, in order to make some checks easier to read.

nspawn: skip /sys-as-tmpfs if we don't use private-network
2015-10-20nspawn: skip /sys-as-tmpfs if we don't use private-networkIago López Galeiras
Since v3.11/7dc5dbc ("sysfs: Restrict mounting sysfs"), the kernel doesn't allow mounting sysfs if you don't have CAP_SYS_ADMIN rights over the network namespace. So the mounting /sys as a tmpfs code introduced in d8fc6a000fe21b0c1ba27fbfed8b42d00b349a4b doesn't work with user namespaces if we don't use private-net. The reason is that we mount sysfs inside the container and we're in the network namespace of the host but we don't have CAP_SYS_ADMIN over that namespace. To fix that, we mount /sys as a sysfs (instead of tmpfs) if we don't use private network and ignore the /sys-as-a-tmpfs code if we find that /sys is already mounted as sysfs. Fixes #1555

2015-10-19tree-wide: whenever we deal with passwords, erase them from memory after useLennart Poettering
A bit snake-oilish, but can't hurt.

2015-10-07util: always enforce O_NOCTTY and O_CLOEXEC in openpt_in_namespace()Lennart Poettering
The child process is shortliving, hence always set O_NOCTTY so that the tty doesn't quickly become controlling TTY and then gives it up again. Also set O_CLOEXEC, because it's cleaner, and doesn't affect the parent anyway.

Add support for naming fds for socket activation and more
2015-10-06core: add support for naming file descriptors passed using socket activationLennart Poettering
This adds support for naming file descriptors passed using socket activation. The names are passed in a new $LISTEN_FDNAMES= environment variable, that matches the existign $LISTEN_FDS= one and contains a colon-separated list of names. This also adds support for naming fds submitted to the per-service fd store using FDNAME= in the sd_notify() message. This also adds a new FileDescriptorName= setting for socket unit files to set the name for fds created by socket units. This also adds a new call sd_listen_fds_with_names(), that is similar to sd_listen_fds(), but also returns the names of the fds. systemd-activate gained the new --fdname= switch to specify a name for testing socket activation. This is based on #1247 by Maciej Wereski. Fixes #1247.
2015-10-02util: rework fgetxattrat_fake() to use O_PATHLennart Poettering
That way, we don't ever open the file, thus leave the atime untouched, and this works even when unprivileged.
2015-09-30tree-wide: remove a number of invocations of strerror() and replace by %mLennart Poettering
Let's clean up our tree a bit, and reduce invocations of the thread-unsafe strerror() by replacing it with printf()'s %m specifier.
2015-09-30basic: split out cpu set specific APIs into cpu-set-util.[ch]Lennart Poettering
2015-09-30util: there cannot be trailing garbage when parsing cpu setsLennart Poettering
extract_first() already skips trailing whitespace, hence no reason to explicitly check for it.
2015-09-30util: rename parse_cpu_set() to parse_cpu_set_and_warn()Lennart Poettering
It's pretty untypical for our parsing functions to log on their own. Clarify in the name that this one does.
2015-09-30tree-wide: clean up log_syntax() usageLennart Poettering
- Rely everywhere that we use abs() on the error code passed in anyway, thus don't need to explicitly negate what we pass in - Never attach synthetic error number information to log messages. Only log about errors we *receive* with the error number we got there, don't log any synthetic error, that don#t even propagate, but just eat up. - Be more careful with attaching exactly the error we get, instead of errno or unrelated errors randomly. - Fix one occasion where the error number and line number got swapped. - Make sure we never tape over OOM issues, or inability to resolve specifiers
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.
2015-09-29util: unify implementation of NOP signal handlerLennart Poettering
This is highly complex code after all, we really should make sure to only keep one implementation of this extremely difficult function around.
2015-09-29tree-wide: port more code to use send_one_fd() and receive_one_fd()Lennart Poettering
Also, make it slightly more powerful, by accepting a flags argument, and make it safe for handling if more than one cmsg attribute happens to be attached.
2015-09-24util: refactor cpu_set parsing into its own functionFilipe Brandenburger
Use the new code in config_parse_cpu_affinity2. Tested by modifying CPUAffinity=... setting in /etc/systemd/system.conf and reloading the daemon, then checking ^Cpus_allowed in /proc/1/status to confirm the correct CPU mask is in place.
2015-09-24s390: add personality supportHendrik Brueckner
Introduce personality support for Linux on z Systems to run particular services with a 64-bit or 31-bit personality.

A variety of mostly unrelated fixes
2015-09-22util.h: order includes, as suggested by CODING_STYLELennart Poettering
Of course, because Linux is broken we cannot actually really order it, and must keep linux/fs.h after sys/mount.h... Yay for Linux!
2015-09-22util: clean-ups to enum parsersLennart Poettering
Never log when we fail due to OOM when translating enums, let the caller do that. Translating basic types like enums should be something where the caller logs, not the translatior functions. Return -1 when NULL is passed to all enum parser functions. The non-fallback versions of the enum translator calls already handle NULL as failure, instead of hitting an assert, and we should do this here, too.
2015-09-22util: minor cleanups for loop_read() and friendsLennart Poettering
When 0 bytes are to be written, make sure to go into read() at least once, in order to validate the parameters, such as the passed fd. Return error on huge values, add a couple of asserts and casts where appropriate.
2015-09-22util: add safe_closedir() similar to safe_fclose()Lennart Poettering
2015-09-22util: introduce {send,receive}_one_fd()David Herrmann
Introduce two new helpers that send/receive a single fd via a unix transport. Also make nspawn use them instead of hard-coding it. Based on a patch by Krzesimir Nowak.
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.
2015-09-09util: introduce safe_fclose() and port everything over to itLennart Poettering
Adds a coccinelle script to port things over automatically.
2015-09-07basic: rework virtualization detection APILennart Poettering
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.
2015-09-04util: document why parse_uid() returns ENXIOLennart Poettering
parse_uid() returns EINVAL for invalid strings, but ENXIO for the (uid_t) -1 user ids in order to distinguish these two cases. Document this.
2015-09-04util: add new uid_is_valid() callLennart Poettering
This simply factors out the uid validation checks from parse_uid() and uses them everywhere. This simply verifies that the passed UID is neither 64bit -1 nor 32bit -1.
