2015-10-05siphash24: expose the internal helper functionsTom Gundersen
2015-10-05siphash24: make siphash24_compress decomposableTom Gundersen
This allows the input to siphash24_compress to be decomposed into smaller chunks and the function to be called on each individual chunk.
2015-10-05siphash24: move last compression iteration from compression step to ↵Tom Gundersen
finalization step The last compression is special as it deals with the length byte, and padding. Move it to the finalization step in preparation for making compression decomposable.

Encapsulate the four state variables in a struct so we can more easily pass them around.
2015-10-01logind: remove warn_melody() logicLennart Poettering
The internal speaker is usually not available on modern latops that support suspend, and even if it is available in the hardware, most distributions turned support for it off in the kernel. And even if it is enabled, it's probably still a bad idea to make use of it for the suspend-failures. If anything a proper sound should be played. Long story short, let's remove support of this anachronism.

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.
2015-09-30log: move log_invalid_utf8() to log.hLennart Poettering
Also, make sure it follows the same scheme as log_syntax() does in its behaviour.
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

2015-09-30log: properly return -EINVAL from log_set_max_level_from_string()Lennart Poettering
If we just return the value we got from log_level_from_string() on failure we'll return -1, which is not a proper error code. log_set_target_from_string() did get this right already, hence let's fix this here too.
2015-09-30fileio: make get_status_field() more genericAaro Koskinen
All users of get_status_field() expect the field pattern to occur in the beginning of a line, and the delimiter is ':'. Hardcode this into the function, and also skip any whitespace before ':' to support fields in files like /proc/cpuinfo. Add support for returning the full field value (currently stops on first whitespace). Rename the function so it's easier to ensure all callers switch to new semantics.

2015-09-29core: rework crash handlingLennart Poettering
This introduces a new systemd.crash_reboot=1 kernel command line option that triggers a reboot after crashing. This also cleans up crash VT handling. Specifically, it cleans up the configuration setting, to be between 1..63 or a boolean. This is to replace the previous logic where "-1" meant disabled. We continue to accept that setting, but only document the boolean syntax instead. This also brings the documentation of the default settings in sync with what actually happens. The CrashChVT= configuration file setting is renamed to CrashChangeVT=, following our usual logic of not abbreviating unnecessarily. The old setting stays support for compat reasons. Fixes #1300

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.

2015-09-29prioq: add introduction commentDavid Herrmann
Add comment to prioq.c explaining what it does. And more importantly, mention that we implement a Heap. It's more than annoying having to figure out what the code actually does, without ever mentioning the word 'heap'.

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.

2015-09-22util.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.

2015-09-16basic: nicer xsprintf and xstrftime assert messagesMichal Schmidt
It's nicer if the assertion failure message from a bad use of xsprintf actually mentions xsprintf instead of the expression the macro is implemented as. The assert_message_se macro was added in the previous commit as an internal helper, but it can also be used for customizing assertion failure messages like in this case. Example: char buf[10]; xsprintf(buf, "This is a %s message.\n", "long"); Before: Assertion '(size_t) snprintf(buf, ELEMENTSOF(buf), "This is a %s message.\n", "long") < ELEMENTSOF(buf)' failed at foo.c:6, function main(). Aborting. After: Assertion 'xsprintf: buf[] must be big enough' failed at foo.c:6, function main(). Aborting.
2015-09-16basic: nicer assert messagesMichal Schmidt
Make sure the assert expression is not macro-expanded before stringification. This makes several assertion failure messages more readable. As an example: assert(streq("foo", "bar")); I'd rather see this: Assertion 'streq("foo", "bar")' failed at foo.c:5, function main(). Aborting. ...than this, though awesome, incomprehensible truncated mess: Assertion '(__extension__ ({ size_t __s1_len, __s2_len; (__builtin_constant_p (( "foo")) && __builtin_constant_p (("bar")) && (__s1_len = strlen (("foo")), __s2_ len = strlen (("bar")), (!((size_t)(const void *)((("foo")) + 1) - (size_t)(cons t void *)(("foo")) == 1) || __s1_len >= 4) && (!((size_t)(const void *)((("bar") ) + 1) - (size_t)(const void *)(("bar")) == 1) || __s2_len >= 4)) ? __builtin_st rcmp (("foo"), ("bar")) : (__builtin_constant_p (("foo")) && ((size_t)(const voi d *)((("foo")) + 1) - (size_t)(const void *)(("foo")) == 1) && (__s1_len = strle n (("foo")), __s1_len < 4) ? (__builtin_constant_p (("bar")) && ((size_t)(const void *)((("bar")) + 1) - (size_t)(const void *)(("bar")) == 1) ? __builtin_strcm p (("foo"), ("bar")) : (__extension__ ({ const unsigned char *__s2 = (const unsi gned char *) (const char *) (("bar")); int __result = (((const unsigned char *) (const char *) (("foo")))[0] - __s2[0]); if (__s1_len > 0 && __result == 0) { __ result = (((const unsigned char *) (const char *) (("foo")))[1] - __s2[1]); if ( __s1_len > 1 && __result == 0) { __result = (((const unsigned char *) (const cha r *) (("foo")))[2] - __s2[2]); if (__s1_len > 2 && __result == 0) __result = ((( const unsigned char *) (const char *) (("foo")))[3] - __s2[3]); } } __result; }) )) : (__builtin_constant_p (("bar")) && ((size_t)(const void *)((("bar")) + 1) - (size_t)(const void *)(("bar")) == 1) && (__s2_len = strlen (("bar")), __s2_len < 4) ?
