2015-04-09util: add shell_maybe_quote() call for preparing a string for shell cmdline ↵Lennart Poettering
inclusion If necessary the passed string is enclosed in "", and all special characters escapes. This also ports over usage in bus-util.c and job.c to use this, instead of a incorrect local implementation that forgets to properly escape.

2015-04-07util: rework cunescape(), improve error handlingLennart Poettering
Change cunescape() to return a normal error code, so that we can distuingish OOM errors from parse errors. This also adds a flags parameter to control whether "relaxed" or normal parsing shall be done. If set no parse failures are generated, and the only reason why cunescape() can fail is OOM.
2015-04-06util: rework rm_rf() logicLennart Poettering
- Move to its own file rm-rf.c - Change parameters into a single flags parameter - Remove "honour sticky" logic, it's unused these days
2015-03-27fix gcc warnings about uninitialized variablesHarald Hoyer
like: src/shared/install.c: In function ‘unit_file_lookup_state’: src/shared/install.c:1861:16: warning: ‘r’ may be used uninitialized in this function [-Wmaybe-uninitialized] return r < 0 ? r : state; ^ src/shared/install.c:1796:13: note: ‘r’ was declared here int r; ^
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.
2015-03-25fstab-generator: don't accept missing root=, but accept root=noneTobias Hunger
And other non-device entries (like fstab does). Mount whatever the user asked to be mounted on / on the kernel command line. Do less sanity check and do *not* bail out when the mount device looks strange or does not exist. This basically makes the changes for deviceless filesystems from yesterday unnecessary and is in line with what we do for filesystems set up in fstab. Remove some code that is now dead (reverting fb02a2775a65 and b0438462). [tomegun: - change patch title/description a bit. - don't touch the /usr logic, that would be a separate change and we don't currently have a convincing use-case for that. - don't bail out on /sys ro. This only makes sense in containers, where we would not be doing this anyway. If there is a use-case we could consider that as a separate patch.]
2015-03-24fstab-generator: Support root on tmpfs (or other deviceless FS)Tobias Hunger
This allows for stateless systems.
2015-03-19Add change_attr_fd()Goffredo Baroncelli
Add change_attr_fd() function to modify the file/directory attribute.
2015-03-16shared - reinstate plymouth_running()Tom Gundersen
This will be used by fsckd. This reverts part of 031886edfc6e96ab778c241035a8d00fb0de99d3.
2015-03-16core: Remove explicit Plymouth integrationJasper St. Pierre
Even if plymouth is running, it might have not displayed the splash yet, so we'll see a few lines on fbcon when we should have otherwise had nothing. Plymouth integration was added to systemd in commit 6faa11140bf776cdaeb8d22d01816e6e48296971. That same day, Plymouth got systemd integration [0]. As such, the Plymouth integration has always been obsolete, and was probably only for older Plymouth's. But I can't imagine anybody running a Plymouth from 2011 with a systemd from 2015. Remove the Plymouth/systemd integration, and let Plymouth's code tell systemd to print the details.

mar 14 20:05:34 fedora22 systemd[4058]: /usr/lib/systemd/system-generators/kdump-dep-generator.sh will be executed. mar 14 20:05:34 fedora22 systemd[4058]: Spawned /usr/lib/systemd/system-generators/kdump-dep-generator.sh as 4059. The second line already says everything.
2015-03-13Check that EWOULDBLOCK is the same as EAGAINZbigniew Jędrzejewski-Szmek
It certainly is everywhere on Linux, but as a courtesy to people doing some strange cross-compilation, check that the assumption holds.
2015-03-13tree-wide: there is no ENOTSUP on linuxDavid Herrmann
Replace ENOTSUP by EOPNOTSUPP as this is what linux actually uses.
2015-03-10util: add rename_noreplaceAlban Crequy
renameat2() exists since Linux 3.15 but btrfs support for the flag RENAME_NOREPLACE was added later. This patch implements a fallback when renameat2() returns EINVAL. EINVAL is the error returned when the filesystem does not support one of the flags.
2015-03-10Add type specifier for intThomas Hindoe Paaboel Andersen
2015-03-09Introduce loop_read_exact helperZbigniew Jędrzejewski-Szmek
Usually when using loop_read(), we want to read the full buffer. Add a helper that mirrors loop_write(), and returns 0 when full buffer was read, and an error otherwise. Use -ENODATA for the short read, to distinguish it from a read error.
2015-03-03shared/util: assume ac when /sys/class/power_supply is missingZbigniew Jędrzejewski-Szmek
On s390 (at least) /sys/class/power_supply is not present. We should treat this like if this directory was empty, and not an error.
2015-03-01shared: AFS is also a network filesystemCristian Rodríguez
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.
2015-02-18shared: introduce cmsg_close_all() callLennart Poettering
The call iterates through cmsg list and closes all fds passed via SCM_RIGHTS. This patch also ensures the call is used wherever appropriate, where we might get spurious fds sent and we should better close them, then leave them lying around.

2015-02-14util: use a shared lookup function for string tablesBruno Bottazzini
Macro DEFINE_STRING_TABLE_LOOKUP expands to a new function for each of the almost 120 tables throghout the code. Move the its implementation to a function (guaranteed to never be inlined), and make the macro expand to an inlined function that calls this function. This saves a few kilobytes from the systemd binary (David: - fix coding-style - use 'ssize_t' to fix 32bit to 64bit propagation - use streq_ptr())
2015-02-12include <poll.h> instead of <sys/poll.h>Thomas Hindoe Paaboel Andersen
include-what-you-use automatically does this and it makes finding unnecessary harder to spot. The only content of poll.h is a include of sys/poll.h so should be harmless.
2015-02-11tree-wide: whenever we include libgen.h, immediately undefine basename()Lennart Poettering
Also, document in adjacent comments and in CODING_STYLE why we do that.
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.
2015-01-28util: add comment explaining hostname_is_valid()Lennart Poettering
2015-01-22import: introduce new mini-daemon systemd-importd, and make machinectl a ↵Lennart Poettering
client to it The old "systemd-import" binary is now an internal tool. We still use it as asynchronous backend for systemd-importd. Since the import tool might require some IO and CPU resources (due to qcow2 explosion, and decompression), and because we might want to run it with more minimal priviliges we still keep it around as the worker binary to execute as child process of importd. machinectl now has verbs for pulling down images, cancelling them and listing them.
2015-01-21util: Add some missing hidden_file() suffixesMartin Pitt
dpkg itself also uses *.dpkg-dist, while .dpkg-{bak,backup,remove} are being used by dpkg-maintscript-helper.
2015-01-21import: add image verification using gpgLennart Poettering
This also adds an initial keyring for the verification, that contains Ubuntu's and Fedora's key. We should probably add more entries sooner or later.
2015-01-20util: make http url validity checks more generic, and move them to util.cLennart Poettering
2015-01-19import-raw: when downloading raw images, generate sparse files if we canLennart Poettering
2015-01-18util: replace RUN_WITH_LOCALE with extended locale functionsCristian Rodríguez
There were two callers, one can use strtod_l() and the other strptime_l(). (David: fix up commit-msg and coding-style)
2015-01-14nspawn: add file system locks for controlling access to container imagesLennart Poettering
This adds three kinds of file system locks for container images: a) a file system lock next to the actual image, in a .lck file in the same directory the image is located. This lock has the benefit of usually being located on the same NFS share as the image itself, and thus allows locking container images across NFS shares. b) a file system lock in /run, named after st_dev and st_ino of the root of the image. This lock has the advantage that it is unique even if the same image is bind mounted to two different places at the same time, as the ino/dev stays constant for them. c) a file system lock that is only taken when a new disk image is about to be created, that ensures that checking whether the name is already used across the search path, and actually placing the image is not interrupted by other code taking the name. a + b are read-write locks. When a container is booted in read-only mode a read lock is taken, otherwise a write lock. Lock b is always taken after a, to avoid ABBA problems. Lock c is mostly relevant when renaming or cloning images.
