2016-01-04resolved: explicitly handle case when the trust anchor is emptyLennart Poettering
Since we honour RFC5011 revoked keys it might happen we end up with an empty trust anchor, or one where there's no entry for the root left. With this patch the logic is changed what to do in this case. Before this patch we'd end up requesting the root DS, which returns with NODATA but a signed NSEC we cannot verify, since the trust anchor is empty after all. Thus we'd return a DNSSEC result of "missing-key", as we lack a verified version of the key. With this patch in place, look-ups for the root DS are explicitly recognized, and not passed on to the DNS servers. Instead, if downgrade-ok mode is on an unsigned NODATA response is synthesized, so that the validator code continues under the assumption the root zone was unsigned. If downgrade-ok mode is off a new transaction failure is generated, that makes this case recognizable.

2015-12-26resolved: generate an explicit transaction error when we cannot reach server ↵Lennart Poettering
via TCP Previously, if we couldn't reach a server via UDP we'd generate an MAX_ATTEMPTS transaction result, but if we couldn't reach it via TCP we'd generate a RESOURCES transaction result. While it is OK to generate two different errors I think, "RESOURCES" is certainly a misnomer. Introduce a new transaction result "CONNECTION_FAILURE" instead.
2015-12-21sd-event: improve debugging of event source errorsDaniel Mack
Printing the pointer variable really doesn't help, so drop that. Instead, add a string lookup table for the EventSourceType enum, and print the type of event source in case of errors.
2015-12-02tests: turn check if manager cannot be intialized into macroZbigniew Jędrzejewski-Szmek
We need to check the same thing in multiple tests. Use a shared macro to make it easier to update the list of errnos. Change the errno code for "unitialized cgroup fs" for ENOMEDIUM. Exec format error looks like something more serious. This fixes test-execute invocation in mock.
2015-11-27selinux: split up mac_selinux_have() from mac_selinux_use()Lennart Poettering
Let's distuingish the cases where our code takes an active role in selinux management, or just passively reports whatever selinux properties are set. mac_selinux_have() now checks whether selinux is around for the passive stuff, and mac_selinux_use() for the active stuff. The latter checks the former, plus also checks UID == 0, under the assumption that only when we run priviliged selinux management really makes sense. Fixes: #1941
2015-11-27tree-wide: expose "p"-suffix unref calls in public APIs to make gcc cleanup easyLennart Poettering
GLIB has recently started to officially support the gcc cleanup attribute in its public API, hence let's do the same for our APIs. With this patch we'll define an xyz_unrefp() call for each public xyz_unref() call, to make it easy to use inside a __attribute__((cleanup())) expression. Then, all code is ported over to make use of this. The new calls are also documented in the man pages, with examples how to use them (well, I only added docs where the _unref() call itself already had docs, and the examples, only cover sd_bus_unrefp() and sd_event_unrefp()). This also renames sd_lldp_free() to sd_lldp_unref(), since that's how we tend to call our destructors these days. Note that this defines no public macro that wraps gcc's attribute and makes it easier to use. While I think it's our duty in the library to make our stuff easy to use, I figure it's not our duty to make gcc's own features easy to use on its own. Most likely, client code which wants to make use of this should define its own: #define _cleanup_(function) __attribute__((cleanup(function))) Or similar, to make the gcc feature easier to use. Making this logic public has the benefit that we can remove three header files whose only purpose was to define these functions internally. See #2008.

2015-11-19sd-event: define a new PREPARING stateLennart Poettering
We already have a state RUNNING and EXITING when we dispatch regular and exit callbacks. Let's introduce a new state called PREPARING that is active while we invoke preparation callbacks. This way we have a state each for all three kinds of event handlers. The states are currently not documented, hence let's add a new state to the end, before we start documenting this.
2015-11-19sd-event: make _ref() calls NOPs when NULL is passed to themLennart Poettering
Let's make _ref() calls happy when NULL is passed to them, and simply return NULL without any assertion logic. This makes them nicely symmetric to the _unref() calls which also are happy to take NULL and become NOPs then.

2015-11-16siphash24: let siphash24_finalize() and siphash24() return the result directlyDaniel Mack
Rather than passing a pointer to return the result, return it directly from the function calls. Also, return the result in native endianess, and let the callers care about the conversion. For hash tables and bloom filters, we don't care, but in order to keep MAC addresses and DHCP client IDs stable, we explicitly convert to LE.

2015-11-16siphash24: change result argument to uint64_tMartin Pitt
Change the "out" parameter from uint8_t[8] to uint64_t. On architectures which enforce pointer alignment this fixes crashes when we previously cast an unaligned array to uint64_t*, and on others this should at least improve performance as the compiler now aligns these properly. This also simplifies the code in most cases by getting rid of typecasts. The only place which we can't change is struct duid's en.id, as that is _packed_ and public API, so we can't enforce alignment of the "id" field and have to use memcpy instead.
