2014-07-18Be more verbose when bind or listen failsZbigniew Jędrzejewski-Szmek
Also be more verbose in devnode_acl_all().
2014-03-18util: replace close_nointr_nofail() by a more useful safe_close()Lennart Poettering
safe_close() automatically becomes a NOP when a negative fd is passed, and returns -1 unconditionally. This makes it easy to write lines like this: fd = safe_close(fd); Which will close an fd if it is open, and reset the fd variable correctly. By making use of this new scheme we can drop a > 200 lines of code that was required to test for non-negative fds or to reset the closed fd variable afterwards.
2014-03-14journald: add support for wall forwardingSebastian Thorarensen
This will let journald forward logs as messages sent to all logged in users (like wall). Two options are added: * ForwardToWall (default yes) * MaxLevelWall (default emerg) 'ForwardToWall' is overridable by kernel command line option 'systemd.journald.forward_to_wall'. This is used to emulate the traditional syslogd behaviour of sending emergency messages to all logged in users.
2014-02-20api: in constructor function calls, always put the returned object pointer ↵Lennart Poettering
first (or second) Previously the returned object of constructor functions where sometimes returned as last, sometimes as first and sometimes as second parameter. Let's clean this up a bit. Here are the new rules: 1. The object the new object is derived from is put first, if there is any 2. The object we are creating will be returned in the next arguments 3. This is followed by any additional arguments Rationale: For functions that operate on an object we always put that object first. Constructors should probably not be too different in this regard. Also, if the additional parameters might want to use varargs which suggests to put them last. Note that this new scheme only applies to constructor functions, not to all other functions. We do give a lot of freedom for those. Note that this commit only changes the order of the new functions we added, for old ones we accept the wrong order and leave it like that.
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.
2013-12-13event: 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.

Just as 'identifier' is strdup-ed and freed, we need to do the same for unit_id.

Always cache the results, and bypass low-level security calls when the respective subsystem is not enabled.
2013-08-19journal: fix parsing of facility in syslog messagesZbigniew Jędrzejewski-Szmek
In 49998b383 (journald: do not overwrite syslog facility when parsing priority) journald started ignoring facility part when reading service stderr to convert to syslog messages. In this case it is fine, because only the priority is allowed. But the same codepath is used for syslog messages, where the facility should be used. Split the two codepaths by explicitly specyfing whether the facility should be ignored or not. https://bugzilla.redhat.com/show_bug.cgi?id=988814
2013-06-20journal: allow callers to specify OBJECT_PID=Zbigniew Jędrzejewski-Szmek
When journald encounters a message with OBJECT_PID= set coming from a priviledged process (UID==0), additional fields will be added to the message: OBJECT_UID=, OBJECT_GID=, OBJECT_COMM=, OBJECT_EXE=, OBJECT_CMDLINE=, OBJECT_AUDIT_SESSION=, OBJECT_AUDIT_LOGINUID=, OBJECT_SYSTEMD_CGROUP=, OBJECT_SYSTEMD_SESSION=, OBJECT_SYSTEMD_OWNER_UID=, OBJECT_SYSTEMD_UNIT= or OBJECT_SYSTEMD_USER_UNIT=. This is for other logging daemons, like setroubleshoot, to be able to augment their logs with data about the process. https://bugzilla.redhat.com/show_bug.cgi?id=951627

2013-04-05Use initalization instead of explicit zeroingZbigniew Jędrzejewski-Szmek
Before, we would initialize many fields twice: first by filling the structure with zeros, and then a second time with the real values. We can let the compiler do the job for us, avoiding one copy. A downside of this patch is that text gets slightly bigger. This is because all zero() calls are effectively inlined: $ size build/.libs/systemd text data bss dec hex filename before 897737 107300 2560 1007597 f5fed build/.libs/systemd after 897873 107300 2560 1007733 f6075 build/.libs/systemd … actually less than 1‰. A few asserts that the parameter is not null had to be removed. I don't think this changes much, because first, it is quite unlikely for the assert to fail, and second, an immediate SEGV is almost as good as an assert.
2013-03-11journald: allow priority of 999, tooLennart Poettering
2013-03-08journal: allow priority 0 in stdout streamMichal Schmidt
Priority 0 is acceptable (it's LOG_EMERG). BTW, I'm not sure why we allow priorities up to 999, but I'm leaving this be for now. http://lists.freedesktop.org/archives/systemd-devel/2013-March/009510.html
2012-11-14build-sys: store journald code in a noinst libraryZbigniew Jędrzejewski-Szmek
The point is to allow the use of journald functions by other binaries. Before, journald code was split into multiple files (journald-*.[ch]), but all those files all required functions from journald.c. And journald.c has its own main(). Now, it is possible to link against those functions, e.g. from test binaries. This constitutes a fix for https://bugzilla.redhat.com/show_bug.cgi?id=872638. The patch does the following: 1. rename journald.h to journald-server.h and move corresponding code to journald-server.c. 2. add journald-server.c and other journald-*.c parts to libsystemd-journal-internal. 3. remove journald-syslog.c from test_journal_syslog_SOURCES, since it is now contained in libsystemd-journal-internal. There are no code changes, apart from the removal of a few static's, to allow function calls between files.
