After 1.8.0 is released, merge it back into master so that
1.8.0 is part of the history of master. That means,
$ git log --first-parent master
will also traverse 1.8.0 and 1.8-rc*.
Also bump the micro version to 1.9.1-dev to indicate that this is
after 1.8.0 is out.

Since using libcurl for connectivity checks, we failed to build
with connectivity checking on travis. Fix that by installing the
required library (from trusty).
Fixes: 4e6967e33d
(cherry picked from commit 1f2b5a2032)
It's not the correct thing to do, but is the same behavior we've done
previously.
DAD is not even going to start until there's carrier and the client would
just wait indefinitely. Ideally, the client would choose not to waiat, but
it currently there's no way the client would discover what is going on.

Fixes: 4e6967e33d
connectivity check functionality should be explicitly set as disabled if
not wanted: this prevents building NM without connectivity check support
without any evident warning on systems where libcurl is not installed.
(cherry picked from commit 4e6967e33d)
Recently we removed libsoup dependency in favor of libcurl.
Connectivity checking functionality was enabled by defaut when libsoup
was detected: do the same now when detecting libcurl.

If users wrote a FQDN in ipv4.dhcp-hostname presumably it's because
they really want to send the full value, not only the host part, so
let's send it as-is.
This obviously is a change in behavior, but only for users that have a
FQDN in ipv4.dhcp-hostname, where it's not clear if they really want the
domain to be stripped.
When the property is unset, we keep sending only the host part of the
system hostname to maintain backwards compatibility.
This commit aligns NM behavior to initscripts.
(cherry picked from commit cf5fab8f55)
Since they are mutually exclusive, pass a string and a boolean to
indicate whether we want to use the hostname or the FQDN option.

Commit #acf1067a allowed to assume connections on already managed
devices. Anyway, in complex scenario with layered connections, during
the startup of NetworkManager, this could interfere with the connection
assumption based on saved state.
So, avoid to re-assume connections on already managed devices during
startup.

managed connections when the lease expires and for assumed

We check the return value of _get_stable_id(); when it is NULL
priv->ndisc would stay NULL too and we would crash when dereferencing
@error.
Actually, _get_stable_id() can never return NULL, so replace the check
with an assertion.

Now that routes can include optional attributes, print the expected
syntax in case of parsing failure.
$ nmcli connection modify dummy ipv4.routes a
Error: failed to modify ipv4.routes: invalid route: Invalid IPv4
address 'a'. The valid syntax is: 'ip[/prefix] [next-hop] [metric]
[attribute=val]... [,ip[/prefix] ...]'.

Most of the IPv6 methods require a non-tentative link local address
configured on the interface; we look at priv->ip6_config to determine
if such address exist. If the configuration is out-of-sync, we may
proceed with configuration when the link-local address does not exist
or is still tentative, especially because we toggle the "disable_ipv6"
sysctl parameter just before, which clears all IPv6 addresses on the
interface.
Ensure that priv->ext_ip6_config_captured is up-to-date before
continuing with the IPv6 configuration, and use it to determine
whether suitable addresses are present.
Fixes test: @ipv6_set_ra_announced_mtu
Fixes: 8f4caab601
(cherry picked from commit 0461da2690)
update_ip6_config() also removes addresses and routes no longer
present externally from the configuration, so it can't be called
before the changes are committed.
This reverts commit 8f4caab601.

Add an example python script to show and set setting's
user-data. This is useful, as nmcli still doesn't support
user data.
(cherry picked from commit 447c766f52)
The user data values are encoded in shell variables named
prefix "NM_USER_". The variable name is an encoded form of the
data key, consisting only of upper-case letters, digits, and underscore.
The alternative would be something like
NM_USER_1_KEY=my.keys.1
NM_USER_1_VAL='some value'
NM_USER_2_KEY=my.other.KEY.42
NM_USER_2_VAL='other value'
contary to
NM_USER_MY__KEYS__1='some value'
NM_USER_MY__OTHER___K_E_Y__42='other value'
The advantage of the former, numbered scheme is that it may be easier to
find the key of a user-data entry. With the current implementation, the
shell script would have to decode the key, like the ifcfg-rh plugin
does.
However, user data keys are opaque identifers for values. Usually, you
are not concerned with a certain name of the key, you already know it.
Hence, you don't need to write a shell script to decode the key name,
instead, you can use it directly:
if [ -z ${NM_USER_MY__OTHER___K_E_Y__42+x} ]; then
do_something_with_key "$NM_USER_MY__OTHER___K_E_Y__42"
fi
Otherwise, you'd first have to search write a shell script to search
for the interesting key -- in this example "$NM_USER_2_KEY", before being
able to access the value "$NM_USER_2_VAL".
(cherry picked from commit 79be44d990)
nm_setting_user_set_data() rejects invalid keys and values, and
can fail. This API is correct never to fail, like the get_data()
only returns valid user-data.
However, the g_object_set() API allows to set the hash directly but
it cannot report errors for invalid values. This API is used to
initialize the value from D-Bus or keyfile, hence it is wrong
to emit g_critial() assertions for untrusted data.
It would also be wrong to silently drop all invalid date, because
then the user cannot get an error message to understand what happend.
The correct but cumbersome solution is to remember the invalid values
separately, so that verify() can report the setting as invalid.
(cherry picked from commit 1dbbf6fb03)
vpn.data, bond.options, and user.data encode their values directly as
keys in keyfile. However, keys for GKeyFile may not contain characters
like '='.
We need to escape such special characters, otherwise an assertion
is hit on the server:
$ nmcli connection modify "$VPN_NAME" +vpn.data 'aa[=value'
Another example of encountering the assertion is when setting user-data key
with an invalid character "my.this=key=is=causes=a=crash".
