a4c1489507 libnm: belatedly expose nm_ethtool_optname_is_feature() in libnm
Also, plan right away to backport this symbol all the way back to
1.14.8. As such, we only need to add it once, with the right linker
version "libnm_1_14_8".

But still, the symbols first appears on a major release 1.20.0.

356a159731 libnm: add nm_setting_ethtool_get_optnames() function
It's rather limiting if we have no API to ask NMSettingEthtool which
options are set.

Note that currently NMSettingEthtool only supports offload features.
In the future, it should also support other options like coalesce
or ring options. Hence, this returns all option names, not only
features.

If a caller needs to know whether the name is an option name, he/she
should call nm_ethtool_optname_is_feature().

c0e075c902 all: drop emacs file variables from source files
We no longer add these. If you use Emacs, configure it yourself.

Also, due to our "smart-tab" usage the editor anyway does a subpar
job handling our tabs. However, on the upside every user can choose
whatever tab-width he/she prefers. If "smart-tabs" are used properly
(like we do), every tab-width will work.

No manual changes, just ran commands:

    F=($(git grep -l -e '-\*-'))
    sed '1 { /\/\* *-\*-  *[mM]ode.*\*\/$/d }'     -i "${F[@]}"
    sed '1,4 { /^\(#\|--\|dnl\) *-\*- [mM]ode/d }' -i "${F[@]}"

Check remaining lines with:

    git grep -e '-\*-'

The ultimate purpose of this is to cleanup our files and eventually use
SPDX license identifiers. For that, first get rid of the boilerplate lines.

13f6f3a410 libnm: rework team handling of JSON config
Completely refactor the team/JSON handling in libnm's NMSettingTeam and
NMSettingTeamPort.

- team handling was added as rh#1398925. The goal is to have a more
  convenient way to set properties than constructing JSON. This requires
  libnm to implement the hard task of parsing JSON (and exposing well-understood
  properties) and generating JSON (based on these "artificial" properties).
  But not only libnm. In particular nmcli and the D-Bus API must make this
  "simpler" API accessible.

- since NMSettingTeam and NMSettingTeamPort are conceptually the same,
  add "libnm-core/nm-team-utils.h" and NMTeamSetting that tries to
  handle the similar code side-by-sdie.
  The setting classes now just delegate for everything to NMTeamSetting.

- Previously, there was a very fuzzy understanding of the provided
  JSON config. Tighten that up, when setting a JSON config it
  regenerates/parses all other properties and tries to make the
  best of it. When modifying any abstraction property, the entire
  JSON config gets regenerated. In particular, don't try to merge
  existing JSON config with the new fields. If the user uses the
  abstraction API, then the entire JSON gets replaced.

  For example note that nm_setting_team_add_link_watcher() would not
  be reflected in the JSON config (a bug). That only accidentally worked
  because client would serializing the changed link watcher to
  GVariant/D-Bus, then NetworkManager would set it via g_object_set(),
  which would renerate the JSON, and finally persist it to disk. But
  as far as libnm is concerned, nm_setting_team_add_link_watcher() would
  bring the settings instance in an inconsistent state where JSON and
  the link watcher property disagree. Setting any property must
  immediately update both the JSON and the abstraction API.

- when constucting a team setting from D-Bus, we would previously parse
  both "config" and abstraction properties. That is wrong. Since our
  settings plugins only support JSON, all information must be present
  in the JSON config anyway. So, when "config" is present, only the JSON
  must be parsed. In the best case, the other information is redudant and
  contributes nothing. In the worse case, they information differs
  (which might happen if the client version differs from the server
  version). As the settings plugin only supports JSON, it's wrong to
  consider redundant, differing information from D-Bus.

- we now only convert string to JSON or back when needed. Previously,
  setting a property resulted in parsing several JSON multiple times
  (per property). All operations should now scale well and be reasonably
  efficient.

- also the property-changed signals are now handled correctly. Since
  NMTeamSetting knows the current state of all attributes, it can emit
  the exact property changed signals for what changed.

- we no longer use libjansson to generate the JSON. JSON is supposed
  to be a machine readable exchange format, hence a major goal is
  to be easily handled by applications. While parsing JSON is not so
  trivial, writing a well-known set of values to JSON is.
  The advantage is that when you build libnm without libjansson support,
  then we still can convert the artificial properties to JSON.

- Requiring libjansson in libnm is a burden, because most of the time
  it is not needed (as most users don't create team configurations). With
  this change we only require it to parse the team settings (no longer to
  write them). It should be reasonably simple to use a more minimalistic
  JSON parser that is sufficient for us, so that we can get rid of the
  libjansson dependency (for libnm). This also avoids the pain that we have
  due to the symbol collision of libjansson and libjson-glib.

309271ac17 all: use nm_clear_g_dbus_connection_signal() helper
I also like this because it's non-obvious that subscription IDs from
GDBusConnection are "guint" (contrary to signal handler IDs which are
"gulong"). So, by using this API you get a compiler error when using the
wrong type.
In the past, when switching to nm_clear_g_signal_handler() this uncovered
multiple bugs where the wrong type was used to hold the ID.

af07ed01c0 shared: build helper "libnm-libnm-core-{intern|aux}.la" library for libnm-core
"libnm-core" implements common functionality for "NetworkManager" and
"libnm".

Note that clients like "nmcli" cannot access the internal API provided
by "libnm-core". So, if nmcli wants to do something that is also done by
"libnm-core", , "libnm", or "NetworkManager", the code would have to be
duplicated.

Instead, such code can be in "libnm-libnm-core-{intern|aux}.la".
Note that:

  0) "libnm-libnm-core-intern.la" is used by libnm-core itsself.
     On the other hand, "libnm-libnm-core-aux.la" is not used by
     libnm-core, but provides utilities on top of it.

  1) they both extend "libnm-core" with utlities that are not public
     API of libnm itself. Maybe part of the code should one day become
     public API of libnm. On the other hand, this is code for which
     we may not want to commit to a stable interface or which we
     don't want to provide as part of the API.

  2) "libnm-libnm-core-intern.la" is statically linked by "libnm-core"
     and thus directly available to "libnm" and "NetworkManager".
     On the other hand, "libnm-libnm-core-aux.la" may be used by "libnm"
     and "NetworkManager".
     Both libraries may be statically linked by libnm clients (like
     nmcli).

  3) it must only use glib, libnm-glib-aux.la, and the public API
     of libnm-core.
     This is important: it must not use "libnm-core/nm-core-internal.h"
     nor "libnm-core/nm-utils-private.h" so the static library is usable
     by nmcli which couldn't access these.

Note that "shared/nm-meta-setting.c" is an entirely different case,
because it behaves differently depending on whether linking against
"libnm-core" or the client programs. As such, this file must be compiled
twice.

8183335878 shared: move "nm-dbus-compat.h" header to "nm-std-aux/nm-dbus-compat.h" 2019-04-18 18:59:09 +02:00

80db06f768 shared: move most of "shared/nm-utils" to "shared/nm-glib-aux"
From the files under "shared/nm-utils" we build an internal library
that provides glib-based helper utilities.

Move the files of that basic library to a new subdirectory
"shared/nm-glib-aux" and rename the helper library "libnm-core-base.la"
to "libnm-glib-aux.la".

Reasons:

 - the name "utils" is overused in our code-base. Everything's an
   "utils". Give this thing a more distinct name.

 - there were additional files under "shared/nm-utils", which are not
   part of this internal library "libnm-utils-base.la". All the files
   that are part of this library should be together in the same
   directory, but files that are not, should not be there.

 - the new name should better convey what this library is and what is isn't:
   it's a set of utilities and helper functions that extend glib with
   funcitonality that we commonly need.

There are still some files left under "shared/nm-utils". They have less
a unifying propose to be in their own directory, so I leave them there
for now. But at least they are separate from "shared/nm-glib-aux",
which has a very clear purpose.

2973d68253 shared: move udev helper to separate directory "shared/nm-udev-aux"
We built (among others) two libraries from the sources in "shared/nm-utils":
"libnm-utils-base.la" and "libnm-utils-udev.la".

It's confusing. Instead use directories so there is a direct
correspondence between these internal libraries and the source files.

7093515777 all: support bridge vlan ranges
In some cases it is convenient to specify ranges of bridge vlans, as
already supported by iproute2 and natively by kernel. With this commit
it becomes possible to add a range in this way:

 nmcli connection modify eth0-slave +bridge-port.vlans "100-200 untagged"

vlan ranges can't be PVIDs because only one PVID vlan can exist.

5801f89f4d all: goodbye libnm-glib
This removes libnm-glib, libnm-glib-vpn, and libnm-util for good.
The it has been replaced with libnm since NetworkManager 1.0, disabled
by default since 1.12 and no up-to-date distributions ship it for years
now.

Removing the libraries allows us to:

* Remove the horrible hacks that were in place to deal with accidental use
  of both the new and old library in a single process.
* Relief the translators of maintenance burden of similar yet different
  strings.
* Get rid of known bad code without chances of ever getting fixed
  (libnm-glib/nm-object.c and libnm-glib/nm-object-cache.c)
* Generally lower the footprint of the releases and our workspace

If there are some really really legacy users; they can just build
libnm-glib and friends from the NetworkManager-1.16 distribution. The
D-Bus API is stable and old libnm-glib will keep working forever.

8db0319198 libnm/lldp: fix leak and bug in nm_lldp_neighbor_dup()
For one, just reassigning copy->attrs leaks the previous
hash table. Fix that.

Also, NMLldpNeighbor instances are not immutable. I think that
is an uglyness, and it would be preferable that they can be sealed.
A sealed object could safely share/ref the internal hash-table. However,
as it is, we cannot just have two NMLldpNeighbor instances share the
same hash-table. Do a full copy.

0d178a968d libnm: rename and expose nm_utils_base64secret_decode() in libnm
A NetworkManager client requires an API to validate and decode
a base64 secret -- like it is used by WireGuard. If we don't have
this as part of the API, it's inconvenient. Expose it.

Rename it from _nm_utils_wireguard_decode_key(), to give it a more
general name.

Also, rename _nm_utils_wireguard_normalize_key() to
nm_utils_base64secret_normalize(). But this one we keep as internal
API. The user will care more about validating and decoding the base64
key. To convert the key back to base64, we don't need a public API in
libnm.

This is another ABI change since 1.16-rc1.

b521f426ab libnm,cli: add NMSettingWireGuard
For now only add the core settings, no peers' data.

To support peers and the allowed-ips of the peers is more complicated
and will be done later. It's more complicated because these are nested
lists (allowed-ips) inside a list (peers). That is quite unusual and to
conveniently support that in D-Bus API, in keyfile format, in libnm,
and nmcli, is a effort.
Also, it's further complicated by the fact that each peer has a secret (the
preshared-key). Thus we probably need secret flags for each peer, which
is a novelty as well (until now we require a fixed set of secrets per
profile that is well known).

243af16c5b Add polkit action for Wi-Fi scans
Previously, Wi-Fi scans uses polkit action
"org.freedesktop.NetworkManager.network-control". This is introduced
in commit 5e3e19d0. But in a system with restrict polkit rules, for
example "org.freedesktop.NetworkManager.network-control" was set as
auth_admin. When you open the network panel of GNOME Control Center, a
polkit dialog will keep showing up asking for admin password, as GNOME
Control Center scans the Wi-Fi list every 15 seconds.

Fix that by adding a new polkit action
"org.freedesktop.NetworkManager.wifi.scan" so that distributions can
add specific rule to allow Wi-Fi scans.
