2013-12-24util: unify SO_PEERCRED/SO_PEERSEC invocationsLennart Poettering
Introduce new call getpeercred() which internally just uses SO_PEERCRED but checks if the returned data is actually useful due to namespace quirks.

2013-12-22shared: switch our hash table implementation over to SipHashLennart Poettering
SipHash appears to be the new gold standard for hashing smaller strings for hashtables these days, so let's make use of it.
2013-12-21journal: replace readdir_r with readdirFlorian Weimer
This commit also adds error handling for failures during directory reading.
2013-12-21journald/server: replace readdir_r with readdirFlorian Weimer
The available_space function now returns 0 if reading the directory fails. Previously, such errors were silently ignored.

2013-12-17journal-file.c: remove redundant assignment of variableThomas Hindoe Paaboel Andersen
we also do 'last_index = (uint64_t) -1;' at the end of the while loop so there is no reason to also do it here.

2013-12-16journal: fix against (theoretical) undefined behaviorShawn Landden
While all the libc implementations I know return NULL when memchr's size parameter is 0, without accessing any memory, passing NULL to memchr is still invalid: C11 7.24.1p2: Where an argument declared as "size_t n" specifies the length of the array for a function, n can have the value zero on a call to that function. Unless explicitly stated otherwise in the description of a particular function in this subclause, pointer arguments on such a call shall still have valid values, as described in 7.1.4. On such a call, a function that locates a character finds no occurrence, a function that compares two character sequences returns zero, and a function that copies characters copies zero characters. see http://llvm.org/bugs/show_bug.cgi?id=18247

2013-12-15catalog: fix language detectionZbigniew Jędrzejewski-Szmek
Detection would fail if language was not specified in the filename but a dot appeared somewhere higher in the path.

2013-12-14Add more _printf_'s for format-nonliteralsThomas Hindoe Paaboel Andersen
Clang is a bit more strict wrt format-nonliterals: http://clang.llvm.org/docs/LanguageExtensions.html#format-string-checking Adding these extra printf attributes also makes gcc able to find more problems. E.g. this patch uncovers a format issue in udev-builtin-path_id.c Some parts looked intetional about breaking the format-nonliteral check. I added some supression for warnings there.
2013-12-13event: be more conservative when returning errors from event handler callbacksLennart Poettering
We really should return errors from event handlers if we have a continous problem and don't know any other solution.
2013-12-13event: rework sd-event exit logicLennart Poettering
With this change a failing event source handler will not cause the entire event loop to fail. Instead, we just disable the specific event source, log a message at debug level and go on. This also introduces a new concept of "exit code" which can be stored in the event loop and is returned by sd_event_loop(). We also rename "quit" to "exit" everywhere else. Altogether this should make things more robus and keep errors local while still providing a way to return event loop errors in a clear way.
2013-12-11journal: pipe journalctl help output into a pagerDjalal Harouni
journalctl help output might run off the screen, so be consistent as other systemd tools do and pipe it into a pager.

2013-12-11journal: add ability to browse journals of running OS containersLennart Poettering
This adds the new library call sd_journal_open_container() and a new "-M" switch to journalctl. Particular care is taken that journalctl's "-b" switch resolves to the current boot ID of the container, not the host.

2013-12-10Ensure unit is journaled for short-lived or oneshot processesDan McGee
In the time it takes to process incoming log messages, the process we are logging details for may exit. This means the cgroup data is no longer available from '/proc'. Unfortunately, the way the code was structured before, we never log _SYSTEMD_UNIT if we don't have this cgroup information. Add an else if case that allows the passed in unit_id to be logged even if we couldn't capture cgroup information. This ensures a command like `journalctl -u run-XXX` will return all log messages from a oneshot process.
2013-12-08Fix memory leak in stdout journal streamsDan McGee
Just as 'identifier' is strdup-ed and freed, we need to do the same for unit_id.
2013-12-06Get rid of our reimplementation of basenameZbigniew Jędrzejewski-Szmek
The only problem is that libgen.h #defines basename to point to it's own broken implementation instead of the GNU one. This can be fixed by #undefining basename.
2013-12-03trivial coding style clean upsThomas Hindoe Paaboel Andersen
- Add space between if/for and the opening parentheses - Place the opening brace on same line as the function (not for udev) From the CODING_STYLE Try to use this: void foo() { } instead of this: void foo() { }
2013-12-03journal: fail silently in sd_j_sendv() if journal is unavailableZbigniew Jędrzejewski-Szmek
"syslog(3) and sd_journal_print() may largely be used interchangeably functionality-wise" according to sd_journal_print(3). This socket should be always available except in rare circumstatances, and we don't random applications to fail on logging, so let's do what syslog did. The alternative of forcing all callers to do error handling for this rare case doesn't really have any benefits, since if they can't log there isn't much they can do anyway. https://bugzilla.redhat.com/show_bug.cgi?id=1023041

2013-11-27journal: simplify pre-allocation logicLennart Poettering
let's just do a single fallocate() as far as possible, and don't distuingish between allocated space and file size. This way we can save a syscall for each append, which makes quite some benefits.

2013-11-25conf-parser: distinguish between multiple sections with the same nameTom Gundersen
Pass on the line on which a section was decleared to the parsers, so they can distinguish between multiple sections (if they chose to). Currently no parsers take advantage of this, but a follow-up patch will do that to distinguish [Address] Address=192.168.0.1/24 Label=one [Address] Address=192.168.0.2/24 Label=two from [Address] Address=192.168.0.1/24 Label=one Address=192.168.0.2/24 Label=two
