In several cases, connection uuids are generated based on
some strings. Change the algorithm, to prefix the hashed
identifier differently for each setting type. This makes
collisions very unlikely.
Also, change the algorithm, to create proper Variant3 UUIDs.
This is a behavioral change, but it only affects code places
that were added since nm-0-9-10 and were not yet part of
a stable release.
There are different types (variants) of UUIDs defined.
Especially variants 3 and 5 are name based variants (rfc4122).
The way we create our UUIDs in nm_utils_uuid_generate_from_string()
however does not create them according to RFC and does not set
the flags to indicate the variant.
Modify the signature of nm_utils_uuid_generate_from_string() to accept
a "uuid_type" argument, so that we later can add other algorithms without
breaking API.
NMIPRoute is used by NMSettingIPConfig, but also
NMIPConfig. In the former case, default routes are (still)
disallowed. But in the NMIPConfig use-case, it can make sense
to expose default routes as NMIPRoute instances.
Relax the restriction on the NMIPRoute API to allow this
future change.
No code actually supports having NMIPRoute instances with
prefix length zero (default routes). Up to now, all such uses
would be a bug.

config.h should be included from every .c file, and it should be
included before any other include. Fix that.
(As a side effect of how I did this, this also changes us to
consistently use "config.h" rather than <config.h>. To the extent that
it matters [which is not much], quotes are more correct anyway, since
we're talking about a file in our own build tree, not a system
include.)
Make the type return GBytes since most in-tree users want that.
Allow the function to accept many more formats as valid hex, including
bytes delimited by ':' and a leading '0x'.
shvar.c has apparently never stripped trailing whitespace, but
obviously a shell doesn't care. Unfortunately NM does. Strip
trailing whitespace before unescaping, to preserve quoted
whitespace.

The gateway is a global property of the IPv4/IPv6 configuration, not
an attribute of any particular address. So represent it as such in the
API; remove the gateway from NMIPAddress, and add it to
NMSettingIPConfig.
Behind the scenes, the gateway is still serialized along with the
first address in NMSettingIPConfig:addresses, and is deserialized from
that if the settings dictionary doesn't contain a 'gateway' key.
Adjust nmcli's interactive mode to prompt for IP addresses and gateway
separately. (Patch partly from Jirka Klimeš.)
NMSettingIP[46]Config let you associate a gateway with each address,
and the writable settings backends record that information. But it
never actually gets used: NMIP4Config and NMIP6Config only ever use
the first gateway, and completely ignore any others. (And in the
common usage of the term, an interface can only have one gateway
anyway.)
So, stop pretending that multiple gateways are meaningful; don't
serialize or deserialize gateways other than the first in the
'addresses' properties, and don't read or write multiple gateway
values either.
Split a base NMSettingIPConfig class out of NMSettingIP4Config and
NMSettingIP6Config, and update things accordingly.
Further simplifications of now-redundant IPv4-vs-IPv6 code are
possible, and should happen in the future.
Add key-value attributes to NMIPAddress and NMIPRoute, and use them to
store IPv4 address labels. Demote NMSettingIP4Config:address-labels to
a D-Bus-only property, and arrange for :addresses setter to read the
labels out of that property when creating the addresses.
Merge NMIP4Address and NMIP6Address into NMIPAddress, and NMIP4Route
and NMIP6Route into NMIPRoute. The new types represent IP addresses as
strings, rather than in binary, and so are address-family agnostic.
This property will indicate that the user wishes the VPN connection
to stay active until explicitly disconnected, even across link changes
or other interruptions.
Add nm-core-types.h, typedefing all of the GObject types in
libnm-core; this is needed so that nm-setting.h can reference
NMConnection in addition to nm-connection.h referencing NMSetting.
Removing the cross-includes from the various headers causes lots of
fallout elsewhere. (In particular, nm-utils.h used to include
nm-connection.h, which included every setting header, so any file that
included nm-utils.h automatically got most of the rest of libnm-core
without needing to pay attention to specifics.) Fix this up by
including nm-core-internal.h from those files that are now missing
includes.
Each plugin defined its own error domain, though none actually defined
any errors. Replace these with appropriate uses of
NM_SETTINGS_ERROR_INVALID_CONNECTION and NM_SETTINGS_ERROR_FAILED.
Move the definition of NMSettingsError to nm-errors, register it with
D-Bus, and verify in the tests that it maps correctly.
Remove a few unused error codes, simplify a few others, and rename
GENERAL to FAILED and HOSTNAME_INVALID to INVALID_HOSTNAME, for
consistency.
Register NMConnectionError with D-Bus on both sides, so that, eg,
connection validation failures in the daemon will translate to the
correct error codes in the client.
Each setting type was defining its own error type, but most of them
had exactly the same three errors ("unknown", "missing property", and
"invalid property"), and none of the other values was of much use
programmatically anyway.
So, this commit merges NMSettingError, NMSettingAdslError, etc, all
into NMConnectionError. (The reason for merging into NMConnectionError
rather than NMSettingError is that we also already have
"NMSettingsError", for errors related to the settings service, so
"NMConnectionError" is a less-confusable name for settings/connection
errors than "NMSettingError".)
Also, make sure that all of the affected error messages are localized,
and (where appropriate) prefix them with the relevant property name.

NM_SETTING_ERROR_PROPERTY_NOT_FOUND -> NM_CONNECTION_ERROR_PROPERTY_NOT_FOUND
NM_SETTING_ERROR_PROPERTY_NOT_SECRET -> NM_CONNECTION_ERROR_PROPERTY_NOT_SECRET

nm_setting_lookup_type_by_quark() was only ever used in places that
were still mistakenly assuming the old style of nm_connection_verify()
errors, where the error message would contain only a property name and
no further explanation. Fix those places to assume that the error will
contain a real error message, and include both the setting name and
the property name.
Given that, there's no longer any need for
nm_setting_lookup_type_by_quark(), so drop it.
When secret providers return the connection hash in GetSecrets(),
this hash should only contain secrets. However, some providers also
return non-secret properties.
for_each_secret() iterated over all entries of the @secrets hash
and triggered the assertion in nm_setting_get_secret_flags() (see
below).
NM should not assert against user provided input. Change
nm_setting_get_secret_flags() to silently return FALSE, if the property
is not a secret.
Indeed, handling of secrets is very different for NMSettingVpn and
others. Hence nm_setting_get_secret_flags() has only an inconsistent
behavior and we have to fix all call sites to do the right thing
(depending on whether we have a VPN setting or not).
Now for_each_secret() checks whether the property is a secret
without hitting the assertion. Adjust all other calls of
nm_setting_get_secret_flags(), to anticipate non-secret flags and
assert/warn where appropriate.
Also, agent_secrets_done_cb() clears now all non-secrets properties
from the hash, using the new argument @remove_non_secrets when calling
for_each_secret().

- fix memleaks if the script contains duplicate lines
- only accept either dhclient or dhcpcd syntax, depending
on the file
- be more strikt in parsing:
- don't use strstr() when parsing dhcpcd.conf. It wrongly
accepts "# send dhcp-client-identifier".
- enfore that keyword are terminated by space. Would no longer
accept "hostnameHOSTNAME"
- be less strict in parsing:
- accept any number of spaces between "send" and "host-name"/
"dhcp-client-identifier"
