How hard can it be to use strtol()? Apparently very. You need to check
errno, the endpointer, and also not pass in an empty string.
Previously, nmc_string_to_uint_base() would silently accept "" as valid
number. That's a bug.
Btw, let's not use strtol() (or nmc_string_to_uint*()). We have
_nm_utils_ascii_str_to_int64(), which gets all of this right.
The same code is used by nmcli. Obviously, clients also need to
parse string representations.
That begs the question whether this should be public API of libnm.
Maybe, but don't decide that now, just reuse the code internally via
"shared/nm-libnm-core-utils.h".
We have code in "shared/nm-utils" which are general purpose
helpers, independent of "libnm", "libnm-core", "clients" and "src".
We have shared code like "shared/nm-ethtool-utils.h" and
"shared/nm-meta-setting.h", which is statically linked, shared
code that contains libnm related helpers. But these helpers already
have a specific use (e.g. they are related to ethtool or NMSetting
metadata).
Add a general purpose helper that:
- depends (and extends) libnm-core
- contains unrelated helpers
- can be shared (meaning it will be statically linked).
- this code can be used by any library user of "libnm.so"
(nmcli, nm-applet) and by "libnm-core" itself. Thus, "src/"
and "libnm/" may also use this code indirectly, via "libnm-core/".
- avoid the memory allocations by not using g_strsplit().
- add a helper function priority_map_parse_str(). This will
be used later, to avoid allocating a NMVlanQosMapping
result, when we don't need it on the heap.
- for the priority mappings, the "from" part is the key and must
be unique. As such, it would make sense to say
$ nmcli connection modify "$PROFILE" -vlan.ingress-priority-map '1:*'
or
$ nmcli connection modify "$PROFILE" -vlan.ingress-priority-map '1:'
to delete any mapping for that priority, regardless of the "to" part.
Add an option to leave the "to" part unspecified. This will be used
later.
nm_utils_parse_inaddr() is trivial enough to reimplement it, instead of calling
nm_utils_parse_inaddr_bin(). Calling nm_utils_parse_inaddr_bin() involves several
things that don't matter for nm_utils_parse_inaddr() -- like assigning
out_addr_family or returning the binary address.
- use nm_auto_decref_json for "json_value" to indicate ownership
transfer.
- don't reuse variable json_element and json_link to construct
watchers list. It's confusing. In general, use different variables
for different purposes.
_nm_utils_team_config_get() determines the type based on the JSON content.
Hence, the caller must validate that the returned GValue is of the expected
type, or it will trigger an assertion/crash.
Use nm_auto*, it's almost always harder to get wrong, because
ownership (and lifetime management of a variable, and what it points
to) is more clearly expressed.
Open vSwitch is the special kid on the block -- it likes to be in charge of
the link lifetime and so we shouldn't be. This means that we shouldn't be
attempting to remove the link: we'd just (gracefully) fail anyways.
More importantly, this also means that we shouldn't care if we see the link
go away. We may already be activating another connection and shouldn't alter
the device state when OpenVSwitch decides to drop the old link.

This will be soon useful as we are going to drop the reference to the
Device objs: so, when a checkpoint is created and a device disappear
(hw removed or sw device deleted) we will be able to correctly perform
the rollback.
that is: when a Device gets unexported from DBus. In this way we will
allow "Devices" property to be rechecked on get() returning an
up-to-date "Devices" property value.

Possibly fixed by https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=7c8f4e6dc30996bff806285730a0bb4e714d3d52
This removes libnm-glib, libnm-glib-vpn, and libnm-util for good.
The it has been replaced with libnm since NetworkManager 1.0, disabled
by default since 1.12 and no up-to-date distributions ship it for years
now.
Removing the libraries allows us to:
* Remove the horrible hacks that were in place to deal with accidental use
of both the new and old library in a single process.
* Relief the translators of maintenance burden of similar yet different
strings.
* Get rid of known bad code without chances of ever getting fixed
(libnm-glib/nm-object.c and libnm-glib/nm-object-cache.c)
* Generally lower the footprint of the releases and our workspace
If there are some really really legacy users; they can just build
libnm-glib and friends from the NetworkManager-1.16 distribution. The
D-Bus API is stable and old libnm-glib will keep working forever.

This is wrong -- we may want to start activating before device is
registered if it the SIM needs unlocking with a PIN code that's included
in the connection.

The patch does not validate.
After 1.16.0 is released, merge it back into master so that
1.16.0 is part of the history of master. That means,
$ git log --first-parent master
will also traverse 1.16.0 and 1.16-rc*.
Also bump the micro version to 1.17.1-dev to indicate that this is
after 1.16.0 is out.
The routing-rule tests generate a number of routing rules and tries to
add and delete them.
For that, _rule_create_random() sets random fields of the rule.
Note that especially interesting are rules that leave most fields
unset (at zero), because they trigger kernel issues rh#1686075 and
rh#1685816.
But a rule has many fields, so in order to generate rules that have most
fields unset, we need to use low probabilities when rolling the dice for
setting a field. Otherwise, most rules end up with several fields set
and don't reproduce the kernel issue (especially the test failed to hit
rh#1686075).
