No need to require the caller to initialize the optional out-argument.
Otherwise we get:

This is required to add objects in the "Types and Values" section and
in the API index. Later, we may want to add useful content in those
empty comments.
<gmodule.h> is implicitly included by <gio/gio.h> which is available
everywhere. For that reason, we would not have to include this header
at all. However, it is recommended to explicitly include <gmodule.h>
where needed.
So, include it where needed -- if <gio/gio.h> wouldn't be there --
and drop it from where it is not needed.
Closing the library will interfere badly as the glib types cannot be
unregistered. We must leak the library handle.
Switch to dlopen() instead of g_module_open(), because the former
supports RTLD_NOLOAD. This is useful for two reasons:
- checking the file prior loading only makes any sense when
dlopen() would actually load a file anew.
- if the library was loaded before, we want to return the handle.
On the other hand, if the library was not loaded, we leak the
handle.
Thereby, refactor the code from if-else blocks to return-early, because
the function nicely does individual steps and if one fails just error
out.
g_object_get_data() and g_object_get_qdata() end up to be identical,
except that g_object_get_data() also requires to intern the string
on every lookup (which involves a hash lookup and locking).
Having a gateway defined when never-default=yes causes troubles in
connection matching and anyway makes no sense.
If the combination is found, remove the gateway during the
normalization phase.

Otherwise the types links would be dangling or resolved to slightly
irrelevant documentation in libnm or completely irrelevant documentation
in libnm-util.

In commit ca000cffbb, we changed to
accept a plugin library name without path. One reason for that
is to keep architecture dependent parts out of the .name file
and possibly support multilib.
However, the shared libraries of VPN plugins are not installed in
a global library search path, but for example into
"/usr/lib64/NetworkManager/libnm-vpn-plugin-openvpn.so".
In that case, specifying "plugin=libnm-vpn-plugin-openvpn.so"
would not be enough to find plugin.
Instead, when configuring a plugin name without path, assume
it is in NMPLUGINDIR directory. Modify nm_vpn_editor_plugin_load_from_file()
to allow path-less plugin-names. Previously such names would be rejected
as not being absolute. This API allows to do file verification
before loading the plugin, but it now supports prepending NMPLUGINDIR
to the plugin name. Basically, this function mangles the plugin_name
argument and checks that such a file exists.
The recently added nm_vpn_editor_plugin_load() continues to behave
as before: it does no checks whatsoever and passes the name directly
to dlopen(). That way, it uses system search paths like LD_LIBRARY_PATH
and performs no checks on the file.

Contrary to nm_vpn_editor_plugin_load_from_file(), this allows
to specify a library name without path. In this case, g_module_open()
(dlopen()) will search for a library in various system directories.
Since commit 3dfbbb227e, we enforce that
the plugin path in the .name file is absolute and we perform several
checks on the file before loading it (ownership, etc).
Relax that, to also allow libray names without path component.
In that case, g_module_open()/dlopen() will search for a library
in various search paths. This allows, to omit absolute paths
in the .name file. The latter is problematic, because by default
we install the .name file in the architecture independent location
/usr/lib/NetworkManager. As such, it should not contain paths
to architecture dependent libraries. With this change, a .name
file can contain only the library name and it will be loaded
using the usual mechanism.
However, specifying absolute paths is still possible and works
same as before, including checking file permissions.
As such, distributions probably should package the VPN plugins
to have no path in the .name file. On the other hand, a user
compiling from source probably wants to specify an absolute
path. The reason is, that the user probably doesn't build the
plugin for multiple achitectures and that way, he can install
the plugin in a separate (private) prefix.
Instead of looking into the keyfile, lookup the "supports-multiple-connections" setting
in the "keys" hash. This has some behavioral difference:
- g_key_file_get_boolean() first does g_key_file_get_value(), and then
converts the string using the private g_key_file_parse_value_as_boolean()
function -- which is case-sensitive, accepts "true|false|0|1" and
considers only the text until the first whitespace.
- now, we put g_key_file_get_string() into the cache "keys" and
parse it with _nm_utils_ascii_str_to_bool(). The latter is
case insensitive, allows also "yes|no|on|off", strips whitespaces.
However, the difference is subtle and shouldn't matter.
The point of this change is to free "keyfile" after construction.
Adding addresses with a prefix of zero is valid. Don't
reject them.
Note that this is an actual bug. If you configure an
address with prefix length zero, nmcli will report:
$nmcli connection
(process:1040): libnm-WARNING **: Ignoring invalid IP4 address: Invalid IPv4 address prefix '0'
For internal compilation we want to be able to use deprecated
API without warnings.
Define the version min/max macros to effectively disable deprecation
warnings.
However, don't do it via CFLAGS option in the makefiles, instead hack it
to "nm-default.h". After all, *every* source file that is for internal
compilation needs to include this header as first.
The problem is that you cannot be sure which patches
were applied on top of a source tree, so the __nm_git_sha
value is unreliable.
Also, after running autoreconf during the package build,
NM_GIT_SHA is reset as well.
We cannot simply compare the single values of option hashes to match
connections because some keys are equivalent to others and also
because keys having a default value should be ignored.
Add the compare_property method to implement custom comparison logic.
When a value of a TYPE_BOTH option is read back from kernel it
contains both string and numeric values ("balance-rr 0"), so we must
chop off the number before adding the option to the setting. Also
change the default values of options to the string form so that the
option matching logic works.
No actual change, let's just not directly call nm_simple_connection_new_from_dbus().
Instead, add a wrapper to define in once place the flags we use for loading the
connection.
In some situations, we want strict checking of errors, for example when
NetworkManager receives a new connection from a client, the connection
must make sense as a whole (and since NetworkManager service is backward
compatible to the clients and not the other way around, there is no
excuse for sending invalid data to the server).
In other situations, we want a best-effort behavior. Like when
NetworkManager sends a connection to its clients, those clients
want to extract as many properties as they understand, but in order
to be forward compatible against newer server versions, invalid
or unknown properties must be accepted.
Previously, a mixture of both was done. Some issues caused a failure
to create a new NMSetting, other invalid parts were just silently
ignored or triggered a g_warning() in glib.
Now allow for both. When doing strict-validation, be more strict and
reject all unknown properties and catch when the user sets an invalid
argument. On the other hand, allow for a best-effort mode that
effectively cannot fail and will return a new NMSetting instance.
For now, add NMSettingParseFlags so that the caller can choose the
old behavior, strict parsing, or best effort.
This patch doesn't have any externally visible change except that
no more g_warnings will be emitted.
_nm_utils_ascii_str_to_int64() was declared in libnm-core's internal
header "nm-core-internal.h" and thus available for libnm-core, libnm,
NetworkManager and related.
It also means, the function was not available in libnm-util, libnm-glib,
clients or dispatcher. So, we either reimplemented it (nmc_string_to_int_base)
or struggle with the awkward strtol* API.
