This is obviously a change in behavior, as we now honor backslash
escape sequences. With this change, all string values can be expressed,
both as option keys and values.
Previously, you could for example not set vpn.secrets to have a ','
and you could not set vpn.data to
nmcli connection modify "$PROFILE" +vpn.data 'ipsec-ike = aes256-sha2_256-modp2048,aes256-sha2_256-modp1536'
Use a relatively simple backslash escaping scheme. The main goal of
the scheme is that it doesn't change behavior for the majority of cases.
It only changes behavior for setting an option if:
- the string contains a backslash
- and if the backslash proceeds one of the few characters that support
escaping now (white space, ',', '\\', and '=').
The only downside here is that backslash is only treated special, if it
preceeds a character that requires escaping. That makes the behavior
non intuitive. However, it allows to write most backslashes without
escaping them as "\\\\" and thus keep previous behavior.
The nmcli getters now also escape the options accordingly. That means,
the string printed by the getter is also a valid input for the setter.

The two modes VALUE_STRSPLIT_MODE_OBJLIST and VALUE_STRSPLIT_MODE_MULTILIST
basically do regular split and afterwards g_strstrip() all values and
remove empty tokens.
That is what the NM_UTILS_STRSPLIT_SET_FLAGS_STRSTRIP flag already does.
Use it.
There should be no change in behavior.
We use the filename of the imported .conf file for "connection.interface-name".
That follows what `wg-quick` does.
However, we also validate that the interface name is valid UTF-8
(otherwise -- as it currently is -- the setting couldn't be send via
D-Bus). As such, we have stricter requirements.
We want to fail early and tell the user when the filename is unsuitable.
Failing later gives a worse user experience, because the failure message
about invalid "connection.interface-name" wouldn't make it clear that
the filename is wrong.
Use the appropriate function to validate "connection.interface-name".
Before:
$ touch $'./a\344b.conf'
$ nmcli connection import type wireguard file $'./a\344b.conf'
Error: failed to import './a?b.conf': Failed to create WireGuard connection: connection.interface-name: 'a?b': interface name must be UTF-8 encoded.
Now:
$ nmcli connection import type wireguard file $'./a\344b.conf'
Error: failed to import './a?b.conf': The name of the WireGuard config must be a valid interface name followed by ".conf".
nm_utils_is_valid_iface_name() is a public API of libnm-core, let's use
our internal API.
$ sed -i 's/\<nm_utils_is_valid_iface_name\>/nm_utils_ifname_valid_kernel/g' $(git grep -l nm_utils_is_valid_iface_name)
nmcli should not perform checks on the interface name length,
this kind of operations should only be performed by the NetworkManager
daemon and not be duplicated inside cli applications.
Most callers would pass FALSE to nm_utils_error_is_cancelled(). That's
not very useful. Split the two functions and have nm_utils_error_is_cancelled()
and nm_utils_error_is_cancelled_is_disposing().
We should use the same "is-valid" function everywhere.
Since nm_utils_ipaddr_valid() is part of libnm, it does not qualify.
Use nm_utils_ipaddr_is_valid() instead.

LLMNR and mDNS settings can have their global default value configured
in "NetworkManager.conf".
Global default values should work the way that all regular values of the property
can be configured explicitly in the connection profile. The special "default" value
only indicates to allow lookup of the global default, but it should not have a
meaning of its own.
Note that if mDNS/LLMNR settings are left unspecified, we will set the
argument to SetLinkMulticastDNS() and SetLinkLLMNR() functions to "",
which means that systemd-resolved decides on a default. Also, depending
on the DNS plugin, the default value differs. This is all fine however.
In this case, the ultimate default value depends on other things (like
the DNS plugin), but each possible value is in fact explicitly
configurable. We also do that for "ipv6.ip6-privacy".
Anyway, cleanup the documentation a bit and try to better explain what
the default is.

The build file in the `client` `common` directory has been improved
by grouping the objects used in properties and by reviewing the
dependencies used by tests built. Finally the indentation has also
been fixed.
The build file in the `client` `common` directory has been improved
by grouping the objects used in properties and by reviewing the
dependencies used by libraries built in the file.
The variable holding the compiler flags, `cflags`, has been renamed
to `c_flags` to be consistent with the rest of build files.
Different objects used in the `test-dispatcher-envp` target
have been grouped together.
The dependency over the `libnm` library has been removed as it is
unnecessary.
The `libnm-core` build file has been improved by applying a set of
changes:
- Indentation has been fixed to be consistent.
- Library variable names have been changed to `lib{name}` pattern
following their filename pattern.
- `shared` prefix has been removed from all variables using it.
- Dependencies have been reviewed to store the necessary data.
- The use of the libraries and dependencies created in this file
has been reviewed through the entire source code. This has
required the addition or the removal of different libraries and
dependencies in different targets.
- Some files used directly with the `files` function have been moved
to their nearest path build file because meson stores their full
path seamessly and they can be used anywhere later.
The `nm-default.h` header is used widely in the code by many
targets. This header includes different headers and needs different
libraries depending the compilation flags.
A new set of `*nm_default_dep` dependencies have been created to
ease the inclusion of different directorires and libraries.
This allows cleaner build files and avoiding linking unnecessary
libraries so this has been applied allowing the removal of some
dependencies involving the linking of unnecessary libraries.
The `shared` build file has been improved by applying a set of
changes:
- Indentation has been fixed to be consistent.
- Unused libraries and dependencies have been removed.
- Dependencies have been reviewed to store the necessary data.
- Set of objects used in targets have been grouped together.
- Header files have been removed from sources lists as it's
unnecessary.
- Library variable names have been changed to `lib{name}` pattern
following their filename pattern.
- `shared` prefix has been removed from all variables using it.
- `version_header` its related configuration `version_conf`
variables have been renamed to `nm_version_macro*` following
its input and final file names.
Functions derived from generators as `configure_file`,
`custom_target` and `i18n.merge_file` can use placeholders like
`@BASENAME@` that removes the extension from the input filename
string.
The output string has been replaced by this placeholder that
allows in some cases the use of less variables.
This will make NetworkManager look up APN, username, and password in the
Mobile Broadband Provider database.
It is mutually exclusive with the apn, username and password properties.
If that is the case, the connection will be normalized to
auto-config=false. This makes it convenient for the user to turn off the
automatism by just setting the apn.
