2016-06-07sd-netlink: fix deep recursion in message destruction (#3455)David Herrmann
On larger systems we might very well see messages with thousands of parts. When we free them, we must avoid recursing into each part, otherwise we very likely get stack overflows. Fix sd_netlink_message_unref() to use an iterative approach rather than recursion (also avoid tail-recursion in case it is not optimized by the compiler).
2016-06-06sd-event: port over to new triple timestamp logicLennart Poettering
2016-06-03sd-netlink: fix sd_netlink_inc_rcvbuf() prototypeLennart Poettering
Drop weird "const" usage, and use size_t for sizes.
2016-05-24Udevadm trivial cleanups (#3331)Zbigniew Jędrzejewski-Szmek
* udevadm-info: use _cleanup_ * udevadm-info: propagate return value from export_devices() * sd-device: add comment and remove unnecessary braces
2016-05-23sd-device: udev-db - handle properties with empty value (#3330)Tom Gundersen
The statemachine was unable to parse properties with empty values, reported in [0]. When reaching the start of the KEY, we would unconditionally read one more character before starting to look for the end-of-line. Simply look for the end-of-line from the first character.

2016-05-15tree-wide: drop spurious "&"s when passing functions aroundZbigniew Jędrzejewski-Szmek
Also adjust indentation in various places.
2016-05-14busctl: use Monitoring interface (#3245)Lars Uebernickel
This is now the recommended way to do monitoring by upstream D-Bus. It's also allowed in the default policy, whereas eavesdrop is not anymore, which effectively broke busctl on many systems.
2016-05-09tree-wide: rename draw_special_char to special_glyphZbigniew Jędrzejewski-Szmek
That function doesn't draw anything on it's own, just returns a string, which sometimes is more than one character. Also remove "DRAW_" prefix from character names, TREE_* and ARROW and BLACK_CIRCLE are unambigous on their own, don't draw anything, and are always used as an argument to special_glyph(). Rename "DASH" to "MDASH", as there's more than one type of dash.
2016-05-05tree-wide: introduce new SOCKADDR_UN_LEN() macro, and use it everywhereLennart Poettering
The macro determines the right length of a AF_UNIX "struct sockaddr_un" to pass to connect() or bind(). It automatically figures out if the socket refers to an abstract namespace socket, or a socket in the file system, and properly handles the full length of the path field. This macro is not only safer, but also simpler to use, than the usual offsetof() + strlen() logic.
2016-05-03sd-netlink: introduce route attribute set APISusant Sahani
Introduce 1. sd_rtnl_message_route_set_table to set table ID 2. sd_rtnl_message_route_set_family to set family Both required to configure route properties.
2016-05-03sd-netlink: fix sd_netlink_message_append_dataSusant Sahani
Also remove the braces add_rtattr not required.

rework "journalctl -M"
2016-04-25nspawn: explicitly remove veth links after use (#3111)Lennart Poettering
* sd-netlink: permit RTM_DELLINK messages with no ifindex This is useful for removing network interfaces by name. * nspawn: explicitly remove veth links we created after use Sometimes the kernel keeps veth links pinned after the namespace they have been joined to died. Let's hence explicitly remove veth links after use. Fixes: #2173
2016-04-25sd-journal: add API for opening journal files or directories by fdLennart Poettering
Also, expose this via the "journalctl --file=-" syntax for STDIN. This feature remains undocumented though, as it is probably not too useful in real-life as this still requires fds that support mmaping and seeking, i.e. does not work for pipes, for which reading from STDIN is most commonly used.
2016-04-22tree-wide: don't assume CLOCK_BOOTIME is generally availableLennart Poettering
Before we invoke now(CLOCK_BOOTTIME), let's make sure we actually have that clock, since now() will otherwise hit an assert. Specifically, let's refuse CLOCK_BOOTTIME early in sd-event if the kernel doesn't actually support it. This is a follow-up for #3037, and specifically: https://github.com/systemd/systemd/pull/3037#issuecomment-210199167

2016-04-17tree-wide: fall back to now(CLOCK_MONOTONIC) if CLOCK_BOOTTIME unsupported ↵Lubomir Rintel
(#3037) It was added in 2.6.39, and causes an assertion to fail when running in mock hosted on 2.6.32-based RHEL-6: Assertion 'clock_gettime(map_clock_id(clock_id), &ts) == 0' failed at systemd/src/basic/time-util.c:70, function now(). Aborting.
2016-04-16sd-bus: use IN_SETZbigniew Jędrzejewski-Szmek
2016-04-13sd-bus: query pid also when searching for supplementary gidsIsmo Puustinen
If the SD_BUS_CREDS_SUPPLEMENTARY_GIDS value is requested, the pid is queried to find out the supplementary gids value from /proc/pid/status. Otherwise sd_bus_creds_get_supplementary_gids() won't work unless some other value in mask triggered fetching the pid information.
2016-04-12core: make sure we generate a nicer error when a linked unit is attempted to ↵Lennart Poettering
be enabled We don't allow using config symlinks to enable units, but the error message we printed was awful. Fix that, and generate a more readable error. Fixes #3010.

2016-04-06sd-device: Allocate enough room for tags stringMartin Pitt
Fix commit 1d88a2: We need to allocate another byte for building the "tags" string, as we append an extra ':' and still need the NUL terminator.

2016-04-05sd-device: fix crash if a device has many tags or devlinksMartin Pitt
strjoina() is unsafe to be used in an unbounded loop as alloca() has no error reporting. Thus devices with a large number of tags or devlinks trigger a segfault in device_properties_prepare() due to overflowing the stack. Rewrite the building of the "tags" and "devlinks" strings using GREEDY_REALLOC() and strpcpy() to work with arbitrarily long strings. This also avoids re-copying the entire string in each loop iteration. Before this commit we always appended one final ":" to "tags". Change this to start with an iniital ":" and for each tag append instead of prepend a ":". This unifies what happens for the first and all subsequent tags so that we can use a for loop. Fixes #2954

tree-wide: merge pager_open_if_enabled() to the pager_open()
2016-02-26tree-wide: merge pager_open_if_enabled() to the pager_open()Alexander Kuleshov
Many subsystems define own pager_open_if_enabled() function which checks '--no-pager' command line argument and open pager depends on its value. All implementations of pager_open_if_enabled() are the same. Let's merger this function with pager_open() from the shared/pager.c and remove pager_open_if_enabled() from all subsytems to prevent code duplication.

2016-02-21networkd: rework how carrier bindings are serializedLennart Poettering
Instead of serializing the interface name, expose the interface index, since that's the only stable identifier.
2016-02-21sd-lldp: rework sd-lldp APILennart Poettering
This reworks the sd-lldp substantially, simplifying things on one hand, and extending the logic a bit on the other. Specifically: - Besides the sd_lldp object only one other object is maintained now, sd_lldp_neighbor. It's used both as storage for literal LLDP packets, and for maintainging info about peers in the database. Separation between packet, TLV and chassis data is not maintained anymore. This should be a major simplification. - The sd-lldp API has been extended so that a couple of per-neighbor fields may be queried directly, without iterating through the object. Other fields that may appear multiple times, OTOH have to be iterated through. - The maximum number of entries in the neighbor database is now configurable during runtime. - The generation of callbacks from sd_lldp objects is more restricted: callbacks are only invoked when actual data changed. - The TTL information is now hooked with a timer event, so that removals from the neighbor database due to TTLs now result in a callback event. - Querying LLDP neighbor database will now return a strictly ordered array, to guarantee stability. - A "capabilities" mask may now be configured, that selects what type of LLDP neighbor data is collected. This may be used to restrict collection of LLDP info about routers instead of all neighbors. This is now exposed via networkd's LLDP= setting. - sd-lldp's API to serialize the collected data to text files has been removed. Instead, there's now an API to extract the raw binary data from LLDP neighbor objects, as well as one to convert this raw binary data back to an LLDP neighbor object. networkd will save this raw binary data to /run now, and the client side can simply parse the information. - support for parsing the more exotic TLVs has been removed, since we are not using that. Instead there are now APIs to extract the raw data from TLVs. Given how easy it is to parse the TLVs clients should do so now directly instead of relying on our APIs for that. - A lot of the APIs that parse out LLDP strings have been simplified so that they actually return strings, instead of char arrays with a length. To deal with possibly dangerous characters the strings are escaped if needed. - APIs to extract and format the chassis and port IDs as strings has been added. - lldp.h has been simplified a lot. The enums are anonymous now, since they were never used as enums, but simply as constants. Most definitions we don't actually use ourselves have eben removed.
2016-02-20sd-device: use (void) before set_iterate callsZbigniew Jędrzejewski-Szmek
set_iterate sets the output argument to NULL on error, and the return value is not used in this case. CID #1306804-09.

Usually, we place the #pragma once before the copyright blurb in header files, but in a few cases we didn't. Move those around, so that we do the same thing everywhere.
