A solicitation loop could result for two cases:
1) a router sent DNS information, then removed that information without
sending it with lifetime=0
2) two routers exist, one sending DNS information and the other not, and
the first router which sends DNS information disappears
In these cases a solicitation would be generated when the DNS information
reached 1/2 its lifetime. A router would then reply to the solicitation
without DNS information, which would then trigger another lifetime check,
which finds that the DNS info is still 1/2 lifetime. Which triggers
another solicitation, etc.
Fix this by ensuring that a solicitation is never sent less than
rtr_solicitation_interval seconds after the last one.
If a route or gateway's priority increased, the item would be added
to the array again without removing the older entry. At the same time
don't bother adding an item with a zero lifetime, since it will just
be removed again by the clean_* functions.
Instead of having it all in the Linux implementation, move all the
timeout logic and most of the processing logic into the NMRDisc
base class so that it can be used by NMFakeRDisc as well. This
will help increase testability since now we can test the timeout
and expiry logic from the fake plugin too.
Utility function for long-running tests to check whether
they should run. It has the same use as g_test_quick(),
but it can also be set via NMTST_DEBUG environment variable.
You can set the compile time default via
CFLAGS='-DNMTST_TEST_QUICK=FALSE' ./configure
and overwrite it at runtime via
NMTST_DEBUG=no-default,quick ./tests/test-my
Use _nm_log() in places that already checked whether logging
is enabled. No need to check again as done by nm_log().

The actual logging implementation is not supposed to be called
directly, because there are macros that capture the call site
information __FILE__, __LINE__, and G_STRFUNC.
Rename the function to make clear that this is the actual
implementation.

We don't want to pass unknown format strings to the logging
macro. Catch that by concatenating "" with the format string.
(cherry picked from commit 2458ddf5e9)
A gnu extension to printf adds the format specifier "%m"
to print @errno. To preserve the error number until the
point where the logging statement is constructed, pass
it as an additional argument to _nm_log().
This is not (yet) used from NM internal code. But systemd is adding
similar functionality to its logging functions. Add the same also to
nm-logging, to support systemd's usage of "%m".

Utility function to simplify the following common code:
if (priv->timeout_id) {
g_source_remove (priv->timeout_id);
priv->timeout_id = 0;
}
to
nm_clear_g_source (&priv->timeout_id);

The identifying properties of a route are (in libnl)
.o_id_attrs = (ROUTE_ATTR_FAMILY | ROUTE_ATTR_TOS |
ROUTE_ATTR_TABLE | ROUTE_ATTR_DST |
ROUTE_ATTR_PRIO),
NM ignores routes other then in table RT_TABLE_MAIN and considers
only the tuple 'family,network/plen,metric' as identifying for a route.
We must also ignore routes with TOS non-zero as we cannot
handle those, i.e. we cannot distinguish between them.

Saw some g_warning() about g_object_weak_unref() trying to unref a non
registed reference. While this does not fix it, let's assert that
situation a step earlier to ease debugging.
Also, move g_object_weak_ref() closer to adding the object into the
@exported hash.

nm_ethernet_address_is_valid() did not check whether @addr was a valid
address in the first place. It only checked whether the address was not
equal to a few notorious MAC addresses.
At the same time, be more forgiving and accept %NULL as argument.
This fixes an assertion nm_ap_match_in_hash().
(cherry picked from commit 842ec6163d)
This is a well known issue that we cannot convert some libnl
objects to NMPlatformObject. The to-string function for libnl
objects is only used for debug logging. No need to assert.

NM already understands the command line argument --g-fatal-warnings
which causes setting of g_log_set_always_fatal().
Also interpret the "fatal-warnings" token in NM_DEBUG environment
variable and in main.debug configuration setting.
Usage hint: either set
$ export NM_DEBUG=RLIMIT_CORE,fatal-warnings
or add the following section to NetworkManager.conf
[main]
debug=RLIMIT_CORE,fatal-warnings

There's no reason the dispatcher test files should have "old" in their
names, since they're testing the current dispatcher interface.
(cherry picked from commit 9cfd9d376f)
For tests with assert-logging enabled, we already printed
the message with g_print(), instead of g_message().
We always want to print this value, because it is important
to reproduce a test failure. Hence, just (always) print
directly to stdout.
Also, add a leading newline, because the output was attached
to the previous line.

When disabling assert-logging with no-expect-message,
print a line at every g_test_assert_expected_messages()
invocation.
(cherry picked from commit 373d09b042)
On the end of the test there should be no unchecked expected
messages. Register a destructor function in nmtst to assert
against that.
Also call nmtst_free() in the destructor. That way, we always release
the allocated data without requiring the test to do it explicitly.
