2013-12-01util: add greedy_realloc0()David Herrmann
Compared to greedy_realloc(), this sets all newly allocated memory to 0. As the old variant has been used a lot for string-handling, we avoid changing it as clearing memory is not needed there.
2013-11-30systemctl: add "systemctl cat"Shawn Landden
2013-12-01util.c: check if return value from ttyname_r is > 0 instead of != 0Thomas Hindoe Paaboel Andersen
We must return a negative error code from getttyname_malloc but that would not be the case if ttyname_r returned a negative value. ttyname_r should only return EBADF, ENOTTY, or ERANGE so it should be safe to change.
2013-11-28bus: add new sd_bus_creds object to encapsulate process credentialsLennart Poettering
This way we can unify handling of credentials that are attached to messages, or can be queried for bus name owners or connection peers. This also adds the ability to extend incomplete credential information with data from /proc, Also, provide a convenience call that will automatically determine the most appropriate credential object for an incoming message, by using the the attached information if possible, the sending name information if available and otherwise the peer's credentials.
2013-11-28util: fix handling of trailing whitespace in split_quoted()Lennart Poettering
Inspired by a patch by Lukas Nykryn.
2013-11-27service: add the ability for units to join other unit's PrivateNetwork= and ↵Lennart Poettering
PrivateTmp= namespaces
2013-11-25shutdown: during final killing spree also send SIGHUP in addition to SIGTERM ↵Lennart Poettering
to deal with shells This makes shutdown a bit faster if debug-shell.service is enabled.
2013-11-21bus: add API calls to escape string components of objects pathsLennart Poettering
2013-11-18Remove duplicate includesKarel Zak
2013-11-13Resolve /dev/console to the active tty instead of just "tty0"Olivier Brunel
When resolving /dev/console one would often get "tty0" meaning the active VT. Resolving to the actual tty (e.g. "tty1") will notably help on boot when determining whether or not PID1 can output to the console.
2013-11-08shutdown: unify handling of reboot() syscall a bitLennart Poettering
2013-11-08Remove dead code and unexport some callsLennart Poettering
"make check-api-unused" informs us about code that is not used anymore or that is exported but only used internally. Fix these all over the place.
2013-11-07util: add circle to special chars we can drawLennart Poettering
2013-11-06util: unify reading of /proc/cmdlineLennart Poettering
Instead of individually checking for containers in each user do this once in a new call proc_cmdline() that read the file only if we are not in a container.
2013-10-28udev: link-config - move naming policy from udev rulesTom Gundersen
This introduces a new key NamePolicy, which takes an ordered list of naming policies. The first successful one is applide. If all fail the value of Name (if any) is used. The possible policies are 'onboard', 'slot', 'path' and 'mac'. This patch introduces a default link file, which replaces the equivalent udev rule.
2013-10-26typo fix in commentThomas Hindoe Paaboel Andersen
2013-10-19kerne-command-line: introduce option 'systemd.restore_state'Tom Gundersen
When set to 0 this will stop tools like the backlight and rfkill tools to restore state from previous boot. This is useful in case the stored state is bogus to the extent that it is preventing you from resetting it (e.g., the backlight settings cause the screen to be off on boot on a system where the backlight can not be adjusted directly from the keyboard).
2013-10-14shared/util: Fix glob_extend() argumentBastien Nocera
glob_extend() would completely fail to work, or return incorrect data if it wasn't being passed the current getopt "optarg" variable as it used the global variable, instead of the passed parameters.
2013-10-13ModernizationZbigniew Jędrzejewski-Szmek
Fixes minor leak in error path in device.c.
2013-10-13util, utf8: make ellipsize take multi-byte characters into accountShawn Landden
rename old versions to ascii_* Do not take into account zerowidth characters, but do consider double-wide characters. Import needed utf8 helper code from glib. v3: rebase ontop of utf8 restructuring work [zj: tweak the algorithm a bit, move new code to separate file]
2013-10-06shared/util: fix off-by-one error in tag_to_udev_nodeDave Reisner
Triggered false negatives when encoding a string which needed every character to be escaped, e.g. "LABEL=/".
2013-10-02nspawn: always copy /etc/resolv.conf rather than bind mountLennart Poettering
We were already creating the file if it was missing, and this way containers can reconfigure the file without running into problems. This also makes resolv.conf handling more alike to handling of /etc/localtime, which is also not a bind mount.
2013-10-01hashmap: randomize hash functions a bitLennart Poettering
2013-10-01util.c: ignore pollfd.revent for loop_read/loop_writeChen Jie
Let read()/write() report any error/EOF.
2013-09-29Fix buffer overrun when enumerating filesZbigniew Jędrzejewski-Szmek

2013-09-19device-nodes: move device node specific code to own fileDave Reisner
In the process, rename udev_encode_string which is poorly named for what it does. It deals specifically with encoding names that udev creates and has its own rules: utf8 is valid but some ascii is not (e.g. path separators), and everything else is simply escaped. Rename it to encode_devnode_name.
2013-09-17Use udev_encode_string in fstab_node_to_udev_nodeDave Reisner
Resolves a longstanding bug which caused this function to wrongly handle (escape) valid utf8 characters.
2013-09-13Advertise hibernation only if there's enough free swapZbigniew Jędrzejewski-Szmek
Condition that is checked is taken from upower: active(anon) < free swap * 0.98 This is really stupid, because the kernel knows the situation better, e.g. there could be two swap files, and then hibernation would be impossible despite passing this check, or the kernel could start supporting compressed swap and/or compressed hibernation images, and then this this check would be too stringent. Nevertheless, until we have something better, this should at least return a true negative if there's no swap. Logging of capabilities in the journal is changed to not strip leading zeros. I consider this more readable anyway. http://cgit.freedesktop.org/upower/tree/src/up-daemon.c#n613 https://bugzilla.redhat.com/show_bug.cgi?id=1007059
2013-09-12Actually allow tabs in environment filesZbigniew Jędrzejewski-Szmek
Fixup for ac4c8d6da8b5e.
2013-09-11Allow tabs in environment filesZbigniew Jędrzejewski-Szmek
bash allows them, and so should we. string_has_cc is changed to allow tabs, and if they are not wanted, they must be now checked for explicitly. There are two other callers, apart from the env file loaders, and one already checked anyway, and the other is changed to check. https://bugs.freedesktop.org/show_bug.cgi?id=68592 https://bugs.gentoo.org/show_bug.cgi?id=481554
2013-08-22Optimize startswith() to macroKay Sievers
I guess it's easier and cleaner anyway to use simple static inline functions instead of defines.
2013-08-20Rename F_TYPE_CMP() to F_TYPE_EQUAL()Zbigniew Jędrzejewski-Szmek
2013-08-11logs-show: limit to 3 lines and use dots if not showing full messageZbigniew Jędrzejewski-Szmek
So far, we would show up to 128 bytes from a message, simply cutting of the rest. With multiline messages, it is quite common for a message to be longer than that, and this model doesn't really work anymore. A new limit is added: up to 3 lines will be shown, unless --full is used (c.f. first line below). The limit for bytes is extended to 300 bytes. An ellipsis will always be used, if some form of truncation occurs. If the tail of the message is cut off, either because of length or line limit, dots will be shown at the end of the last line. If this last line is short, the dots will be simply appended. If the last line is too long for that, it will be ellipsized with dots at the very end. Note that the limits are in bytes, not characters, and we suck at outputting unicode strings (c.f. last three lines below). Aug 11 10:46:21 fedora python[67]: test message line line...

2013-07-18util: add split_pair() for splitting foo=bar stringsLennart Poettering
2013-07-17util: make gcc shut up by passing a 0 mode param to open()Lennart Poettering
If we pass a variable to open()'s flags parameter it really wants a mode parameter too, otherwise some gcc version whine. Hence, pass 0 in that case.
2013-07-17util: make some gcc versions shut up regarding unintialized variable accessLennart Poettering
2013-07-16util.c:is_locale_utf8(): check, if "C" was set on purposeHarald Hoyer
If you have a ASCII only terminal, there is no way to set the charmap to ANSI_X3.4-1968, other than using LC_CTYPE=C. We don't want to assume a UTF-8 capable terminal in this case and only do so, if LANG, LC_ALL and LC_CTYPE are unset.
2013-07-16journal: add logging of effective capabilities _CAP_EFFECTIVEShawn Landden
I think this is the most important of the capabilities bitmasks to log.
2013-07-16util: recognize 'ncp' as an alias to 'ncpfs'Frederic Crozat
ncp is also used for Netware mount point, recognize it as such. Fixes https://bugzilla.novell.com/show_bug.cgi?id=828905.
2013-07-02journald: drop (deleted) from _EXE= fieldsZbigniew Jędrzejewski-Szmek
The kernel adds those when the file is deleted, but we don't really care if the file is still there or not. The downside is that if the filename ends in ' (deleted)', this part of the filename will be removed. Too bad.
2013-06-10journalctl: allow the user to specify the file(s) to useZbigniew Jędrzejewski-Szmek
This is useful for debugging and feels pretty natural. For example answering the question "is this big .journal file worth keeping?" is made easier.
2013-06-10Properly check for overflow in offsetsZbigniew Jędrzejewski-Szmek
2013-06-09Allow for the use of @ in remote host callsDaniel Wallace
Without this you have to use %40 with the -H flag because dbus doesn't like the @ sign being unescaped.
2013-05-30systemctl: suggest 'systemctl daemon-reload' without --systemZbigniew Jędrzejewski-Szmek
--system is default anyway, and some poor user might type 9 characters without needing to.
2013-05-07hostname: only suppress setting of pretty hostname if it is non-equal to the ↵Lennart Poettering
static hostname and if the static hostname is set, too https://bugzilla.redhat.com/show_bug.cgi?id=957814
2013-05-06systemd-sleep: add support for freeze and standbyZbigniew Jędrzejewski-Szmek
A new config file /etc/systemd/sleep.conf is added. It is parsed by systemd-sleep and logind. The strings written to /sys/power/disk and /sys/power/state can be configured. This allows people to use different modes of suspend on systems with broken or special hardware. Configuration is shared between systemd-sleep and logind to enable logind to answer the question "can the system be put to sleep" as correctly as possible without actually invoking the action. If the user configured systemd-sleep to only use 'freeze', but current kernel does not support it, logind will properly report that the system cannot be put to sleep. https://bugs.freedesktop.org/show_bug.cgi?id=57793 https://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=7e73c5ae6e7991a6c01f6d096ff8afaef4458c36 http://lists.freedesktop.org/archives/systemd-devel/2013-February/009238.html SYSTEM_CONFIG_FILE and USER_CONFIG_FILE defines were removed since they were used in only a few places and with the addition of /etc/systemd/sleep.conf it becomes easier to just append the name of each file to the dir name.
2013-05-02Add __attribute__((const, pure, format)) in various placesZbigniew Jędrzejewski-Szmek
I'm assuming that it's fine if a _const_ or _pure_ function calls assert. It is assumed that the assert won't trigger, and even if it does, it can only trigger on the first call with a given set of parameters, and we don't care if the compiler moves the order of calls.
2013-04-30id128: when taking user input for a 128bit ID, validate syntaxLennart Poettering
Also, always accept both our simple hexdump syntax and UUID syntax.
2013-04-25util: rework safe_atod() to be locale-independentLennart Poettering
This adds some syntactic sugar with a macro RUN_WITH_LOCALE() that reset the thread-specific locale temporarily.
