2014-05-21logind: don't apply RemoveIPC= to system usersLennart Poettering
We shouldn't destroy IPC objects of system users on logout. http://lists.freedesktop.org/archives/systemd-devel/2014-April/018373.html This introduces SYSTEM_UID_MAX defined to the maximum UID of system users. This value is determined compile-time, either as configure switch or from /etc/login.defs. (We don't read that file at runtime, since this is really a choice for a system builder, not the end user.) While we are at it we then also update journald to use SYSTEM_UID_MAX when we decide whether to split out log data for a specific client.

2014-04-12journal: properly detect language specified in lineZbigniew Jędrzejewski-Szmek
... it turns out that the duplicates in our own catalog were not real duplicates, but translations.
2014-04-12journal: cleanup up error handling in update_catalog()Zbigniew Jędrzejewski-Szmek
- Negative/positive errno mixup caused duplicates not to be detected properly. Now we get a warning about some duplicate entries in our own catalogs... - Errors in update_catalog would be ignored, but they should not be.
2014-04-12Unify GREEDY_REALLOC and GREEDY_REALLOC_TZbigniew Jędrzejewski-Szmek
greedy_realloc() and greedy_realloc0() now store the allocated size as the count, not bytes. Replace GREEDY_REALLOC uses with GREEDY_REALLOC_T everywhere, and then rename GREEDY_REALLOC_T to GREEDY_REALLOC. It is just too error-prone to have two slightly different macros which do the same thing.

2014-03-24util: replace close_pipe() with new safe_close_pair()Lennart Poettering
safe_close_pair() is more like safe_close(), except that it handles pairs of fds, and doesn't make and misleading allusion, as it works similarly well for socketpairs() as for pipe()s...
2014-03-24sd-event: rework API to support CLOCK_REALTIME_ALARM and ↵Lennart Poettering
CLOCK_BOOTTIME_ALARM, too
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.
2014-03-18microhttpd-util: avoid double free on errorZbigniew Jędrzejewski-Szmek
It seems that resources are properly deallocated by MHD_destroy_response, even if enqueuing the request fails. Also replace a trivial printf with alloca and fixup log message (it'll now be something like "Connection from CN=some.host.name", which seems clear enough.)
2014-03-18journal-remote: do not attempt to read from µhttpd connectionsZbigniew Jędrzejewski-Szmek
This chunk got lost in one of the rebases :(

2014-03-17journal-remote: implement inheriting http(s) socketsZbigniew Jędrzejewski-Szmek
Now --listen-http=-3 --listen-https=-4 can be used to spawn a µhttpd server on those two ports, in http and https modes respectively. As before, --listen-http=3 --listen-https=4 will launch µhttpd servers on ports 3 and 4.
2014-03-17microhttpd-util: use static buffer for static messagesZbigniew Jędrzejewski-Szmek
Most of the messages we send do not require a allocating and freeing a buffer, to optimize this by using const strings. Also, rename respond_error to mhd_respond*, since it is used not only for errors. Make use of information from printf to avoid one extra call to strlen.
2014-03-17journal-remote: HTTP(s) supportZbigniew Jędrzejewski-Szmek
The whole tool is made dependent on µhttpd availability. It should be easy to make the µhttpd parts conditional, but since transfer over HTTP seems to be the primary use case, currently this is not done. Current implementation uses nested epoll loops: sd-event is used for the external event loop, and µhttpd uses epoll in its own loop. Unfortunately µhttpd does not expose enough information to add the descriptors it uses to the external event loop. This means that starvation of other events is possible, if one of the inner µhttpd loops is constantly busy. This means that µhttpd servers should not be mixed with other sources. The TLS authentication parts haven't been really tested properly, and should not be take too seriously.

2014-03-17journal-gatewayd: check if certificate is signed by CAZbigniew Jędrzejewski-Szmek
If --trust=ca.crt is used, only clients presenting certificates signed by the ca will be allowed to proceed. No hostname matching is performed, so any client wielding a signed certificate will be authorized. Error functions are moved from journal-gateway to microhttp-util and made non-static, since now they are used in two source files.
2014-03-17journal-gatewayd: log to journal from gnutlsZbigniew Jędrzejewski-Szmek
Prefix "gnutls: " is added. Some semi-random mapping of gnutls levels to syslog levels is done, but since gnutls levels seem to be used rather loosely, most end up as debug.
2014-03-17journal-gatewayd: ask clients to provide certificatesZbigniew Jędrzejewski-Szmek
A certificate authority certificate will be presented to clients, causing them to present their client certificate, if it is signed by this authority (default behaviour of most clients). No certificate checking is actually performed.

2014-03-16Use strlen even for constant stringsJosh Triplett
GCC optimizes strlen("string constant") to a constant, even with -O0. Thus, replace patterns like sizeof("string constant")-1 with strlen("string constant") where possible, for clarity. In particular, for expressions intended to add up the lengths of components going into a string, this often makes it clearer that the expression counts the trailing '\0' exactly once, by putting the +1 for the '\0' at the end of the expression, rather than hidden in a sizeof in the middle of the expression.
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.
2014-03-07Make tables for DEFINE_STRING_TABLE_LOOKUP consistentDaniel Mack
Bring some arrays that are used for DEFINE_STRING_TABLE_LOOKUP() in the same order than the enums they reference. Also, pass the corresponding _MAX value to the array initalizer where appropriate.
2014-03-05journal: forget file after encountering an errorZbigniew Jędrzejewski-Szmek
If we encounter an inconsistency in a file, let's just ignore it. Otherwise, after previous patch, we would try, and fail, to use this file in every invocation of sd_journal_next or sd_journal_previous that happens afterwards.
2014-03-05journal: assume that next entry is after previous entryZbigniew Jędrzejewski-Szmek
With a corrupted file, we can get in a situation where two entries in the entry array point to the same object. Then journal_file_next_entry will find the first one using generic_arrray_bisect, and try to move to the second one, but since the address is the same, generic_array_get will return the first one. journal_file_next_entry ends up in an infinite loop. https://bugzilla.redhat.com/show_bug.cgi?id=1047039
2014-03-03conf-parse: rename config_parse_level() to config_parse_log_level()Lennart Poettering
"level" is a bit too generic, let's clarify what kind of level we are referring to here.
2014-02-27journalctl: refuse extra arguments with --verify and similarZbigniew Jędrzejewski-Szmek
Positional arguments only make sense with the default action. For other actions, complain instead of ignoring them silently.

2014-02-23core: clean up some confusing regarding SI decimal and IEC binary suffixes ↵Lennart Poettering
for sizes According to Wikipedia it is customary to specify hardware metrics and transfer speeds to the basis 1000 (SI decimal), while software metrics and physical volatile memory (RAM) sizes to the basis 1024 (IEC binary). So far we specified everything in IEC, let's fix that and be more true to what's otherwise customary. Since we don't want to parse "Mi" instead of "M" we document each time what the context used is.
2014-02-21journald: ignore failure to watch hostname_fd on older kernelsDave Reisner
Prior to 3.2, /proc/sys/kernel/hostname isn't a pollable file and sd_event_add_io will return EPERM. Ignore this failure, since it isn't critical to journald operation. Reported and tested by user sraue on IRC.

2014-02-20journal: fix compiler warning in journal_file_append_data()Daniel Mack
gcc (4.8.2, arm) does not understand that journal_file_append_field() will always set 'fo' when it returns 0, so this warning is bogus. Anyway, fix it by initialiting fo = NULL.
2014-02-20journal: fix compiler warning in real_journal_next()Daniel Mack
gcc (4.8.2, arm) does not understand that next_beyond_location() will always set 'p' when it returns > 0. Initialize p in order to fix this.
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.

2014-02-19make gcc shut upLennart Poettering
If -flto is used then gcc will generate a lot more warnings than before, among them a number of use-without-initialization warnings. Most of them without are false positives, but let's make them go away, because it doesn't really matter.
