When subclassing a GObject type, the class and object structs
must be available and defined in the header.
For libnm, and in particular for NMSetting classes, we don't want
users to subclass NMSetting. It also doesn't work, because libnm
has internal code that is necessary to hook up the NMSetting class.
You cannot define your own type and make it work together with
libnm.
Having the structs in public headers limits what we can do with them.
For example, we could embed the private data directly in the structures
and avoid the additional indirection.
This is an API break, but for something that most likely nobody cares
about. Or better, nobody should care about. API is not what is
accidentally defined in a header, API was the library provides to
meaningfully use. Subclassing these types is not meaningful and was
only accidentally possible so far.
Only hide the structs for now. More cleanup is possible later. We shall
however aim to keep the padding and struct layout to not also break ABI.
(cherry picked from commit e46d484fae)
Modern WPA3 authentication methods like SAE and WPA-EAP-SUITE-B-192 need
to have management frame protection set to required according to the
standard. Since the last commit, we enforce this automatically when
key-mgmt is set to 'owe', 'sae' or 'wpa-eap-suite-b-192', so disabling
it manually should not be possible.
Add a check to the pmf property that makes sure it can't be set to
'disabled' or 'optional' when one of those key-mgmt methods is used.
The key-mgmt property of NMSettingWirelessSecurity is slightly confusing
when you know there's also a wpa_supplicant configuration option called
"key_mgmt". Our property is not the same as that supplicant option even
though they do have things in common. NMs key-mgmt is not exactly meant
to configure which AKM suites you want to use, but rather which method
of wifi security is being used (so "wpa2+wpa3 personal", "wpa3 personal
only" or "wpa3 enterprise only").
Try to make this a bit clearer in the documentation of the property by
rewriting it and listing those security methods.
A small bug sneaked into commit 3ef3733c81 ('wireless-security: ensure
Mesh networks can't use anything but SAE') during review: Instead of
allowing only "sae" or "none" as key-mgmt, we now disallow "sae" and
"none", but allow anything else. This is obviously not what was
intended, so fix the check.
Also move the valid_key_mgmt check back up to where it was before that
commit, it seems we want to apply that check in all cases.
"libnm-core/" is rather complicated. It provides a static library that
is linked into libnm.so and NetworkManager. It also contains public
headers (like "nm-setting.h") which are part of public libnm API.
Then we have helper libraries ("libnm-core/nm-libnm-core-*/") which
only rely on public API of libnm-core, but are themself static
libraries that can be used by anybody who uses libnm-core. And
"libnm-core/nm-libnm-core-intern" is used by libnm-core itself.
Move "libnm-core/" to "src/". But also split it in different
directories so that they have a clearer purpose.
The goal is to have a flat directory hierarchy. The "src/libnm-core*/"
directories correspond to the different modules (static libraries and set
of headers that we have). We have different kinds of such modules because
of how we combine various code together. The directory layout now reflects
this.
