Previously, the daemon would just use syslog with LOG_PERROR when run with
--debug option, even when actually configured to log into the journal.
Let's respect the configuration, but preserve the logging to stderr.
Works by dumb luck for in-tree build, because the .deps files that are
meant for the distribution happen to be the builddir. The out-of-tree
builds would generate an empty file.
nm_utils_exp10() is a better name, because it reminds of the function
exp10() from <math.h> which has a similar purpose (but whose argument
is double, not gint16).
"build_clean.sh" is used to generate a distribution tarball. The tarball
contains pregenerated man pages with default values for paths, which in
turn depend on the configure options when creating the tarball.
Previously, the man page would have paths like "usr/local/etc/NetworkManager/...",
which doesn't seem the best choice for a default man page.
Explicitly set the installation paths.
Also, --disable-dependency-tracking in this mode. It may speed up the
build.
We also dist libnm/nm-property-docs.xml, so depending on
whether we build from git or source tarball, the file
is in $(srcdir) or $(builddir).

There are very few places where we actually use floating point
or #include <math.h>.
Drop that library, although we very likely still get it as indirect
dependency (e.g. on my system it is still dragged in by libsystemd.so,
libudev.so and libnl-3.so).
One day, I wish we would have more setting metadata in shared via
"shared/nm-setting-metadata.h", ready for nmcli and nmtui to use
(by statically linking against the internal API).
Anyway, it is still unused, so drop the files from the SOURCES of
nmcli.
"$(srcdir)/clients/cli/settings.c" includes "$(builddir)/clients/cli/settings-docs.c",
hence, we need "-I$(builddir)/clients/cli".
This basically reverts commit bbce089840,
but adds dependencies so that the build directory exists.
The sources should reach files in the $builddir using #include "".
Besides, it is not guarranteed to be around:
CC shared/clients_cli_nmcli-nm-setting-metadata.o
cc1: error: ./clients/cli: No such file or directory [-Werror=missing-include-dirs]
cc1: all warnings being treated as errors

It's not sufficient to make nm-core-enum-types.[ch] depend on the
dirstamp, because they also depend on their own stamps that are to be
placed in libnm-core.
$ make libnm-core/nm-core-enum-types.h.stamp
GEN libnm-core/nm-core-enum-types.h

When rc-manager=file other services may overwrite resolv.conf at any
time. We don't support merging configurations in resolv.conf but we can
be more tolerant avoiding updating resolv.conf when not strictly needed.
In this case, if the last write of resolv.conf had no nameservers (nor
options), reset the "dns_touched" flag in order to avoid resetting
resolv.conf when quitting (so, potentially overwriting some other
service configuration there).

GLib 2.52 added a G_GNUC_PRINTF attribute to
g_dbus_message_new_method_error(). This triggered warning in
NetworkManager when built with -Wformat, which is an error when built
with -Werror=format-security. It seems that gcc isn't smart enough to
see that (foo = "bar") should be treated as a literal.
Fortunately there is a g_dbus_message_new_method_error_literal()
function which does not take printf-style arguments, and we don't need
them, so we can use that.

CURLOPT_CONNECTTIMEOUT or CURLOPT_TIMEOUT only make sense if libcurl is
handling the I/O loop (the "easy" interface); we need to implement our
own timeout.
Factor out the conclusion of the connectivity check. This will allow us
to finish the connectivity check on other occassions than a successful
connection end. Most importantly on timeouts; but it will also allow us
to short-circuit the check when we conclude it without reading the full
response.
No need to create a separate NMUdevClient instance for all devices.
Instead, have one "struct udev" instance in NMClient and pass
it down during object construction.
GUdevClient always creates a monitor instance, even if there are no subsystems
or handlers defined. Hence the first iteration of NMUdevClient did that as
well.
I think that can be avoided however. We only need a monitor when there is
a event handler subscribed. Contrary to GUdevClient, we know that from the
very beginning.
The IPv4 Strict Reverse Path Forwarding filter (RFC 3704) drops legitimate
traffic when the same route is present on multiple interfaces, which is a
pretty common scenario for IPv4 hosts. In particular, if the traffic is
routable via multiple interfaces it drops traffic incoming via the device that
has lower metric on the route to the originating network.
Among other things, this disrupts existing connection when the user connected
to the Internet via Wi-Fi activates a Wired Ethernet connection that also has a
default route. Also, the Strict filter (and Reverse Path filters in general)
provide practically no value to hosts that have a default route.
The solution this patch uses is to detect scenarios where Strict filter is
known to interfere and switch to a saner RP filter on the affected links.
Routes to the same network on multiple interfaces is a good indication the RP
filter would drop the legitimate traffice from the link with a lower metric.
This includes the default routes.
In such cases, we switch to the Loose Reverse Path Forwarding. This addresses
the problems the multihomed hosts face, at the cost of disabling filtering
altogether when a default route is present. A Feasible Path Reverse Path
Forwarding would address the main problems with the Strict filter, but it's
not implemented by the Linux kernel.
