Some targets are missing dependencies on some generated sources in
the meson port. These makes the build to fail due to missing source
files on a highly parallelized build.
These dependencies have been resolved by taking advantage of meson's
internal dependencies which can be used to pass source files,
include directories, libraries and compiler flags.
One of such internal dependencies called `core_dep` was already in
use. However, in order to avoid any confusion with another new
internal dependency called `nm_core_dep`, which is used to include
directories and source files from the `libnm-core` directory, the
`core_dep` dependency has been renamed to `nm_dep`.
These changes have allowed minimizing the build details which are
inherited by using those dependencies. The parallelized build has
also been improved.
Note that:
- we compile some source files multiple times. Most notably those
under "shared/".
- we include a default header "shared/nm-default.h" in every source
file. This header is supposed to setup a common environment by defining
and including parts that are commonly used. As we always include the
same header, the header must behave differently depending
one whether the compilation is for libnm-core, NetworkManager or
libnm-glib. E.g. it must include <glib/gi18n.h> or <glib/gi18n-lib.h>
depending on whether we compile a library or an application.
For that, the source files need the NETWORKMANAGER_COMPILATION #define
to behave accordingly.
Extend the define to be composed of flags. These flags are all named
NM_NETWORKMANAGER_COMPILATION_WITH_*, they indicate which part of the
build are available. E.g. when building libnm-core.la itself, then
WITH_LIBNM_CORE, WITH_LIBNM_CORE_INTERNAL, and WITH_LIBNM_CORE_PRIVATE
are available. When building NetworkManager, WITH_LIBNM_CORE_PRIVATE
is not available but the internal parts are still accessible. When
building nmcli, only WITH_LIBNM_CORE (the public part) is available.
This granularily controls the build.
Makes sense in order for the user to know that they're actually typing
the password (edited just to illustrate the point, the actual output was
shamefully messy and perhaps needs fixing too):
$ nmcli c up Wrathmosphere
Passwords or encryption keys are required to access the wireless network 'Wrathmosphere'.
Password (802-1x.password): *********
Having it in libnm doesn't make any sense and prevents using it for more
internal functionality.
Too bad nm_utils_wifi_strength_bars() is already a public API.
No problem -- replace it with a compatible yet dumber equivalent.
History is probably even not useful at all outside the interactive edit
mode, but that is another story. This just avoids awkward surprises,
such as:
https://bugzilla.gnome.org/show_bug.cgi?id=791200
Source files for enum types are generated by passing segments of the
source code of the files to the `glib-mkenums` command.
This patch removes those parameters where source code is used from
meson build files by moving those segmeents to template files.

In most cases, it copies the entire strv needlessly.
We can do better.
Also, the max_tokens argument is handled wrongly (albeit
not used anywhere anymore).
nmc_strsplit_set() handles max_token wrong. It cannot call
g_strsplit_set() with max_token first, and then split empty
words. You cannot use g_strsplit_set() to achieve what
nmc_strsplit_set() wants to do, unless you first split all
tokens, then them construct them together again -- thereby
loosing the delimiters.
Anyway, there are just a few caller that do essentially the same.
Refactor the code to not use nmc_strsplit_set().
Probably not critical, because it will still include
the terminating NULL, and just continue to fill the
temporary buffer with static addresses.

We also do this for libnm, where it causes visible changes
in behavior. But if somebody would rely on the hashing implementation
for hash tables, it would be seriously flawed.
Next we will use siphash24() instead of the glib version g_direct_hash() or
g_str_hash(). Hence, the "nm-utils/nm-hash-utils.h" header becomes very
fundamental and will be needed basically everywhere.
Instead of requiring the users to include them, let it be included via
"nm-default.h" header.
Change the activation procedure for connections that require secrets
in the following way:
- nmcli creates a secret-agent and leaves it disabled so that
incoming requests are queued
- nmcli calls ActivateConnection()
- when the method returns success, the secret-agent gets enabled and
all queued requests are processed
When the user activates a connection which is already auto-activating,
NM will deactivate the current active-connection and will call
CancelGetSecrets() for it before the new ActivateConnection()
returns. In this way, when the secret-agent is enabled by nmcli, we
have the guarantee that there aren't any queued requests for
the deactivating connections.

nmcli typically doesn't run setuid, nor uses file capabilities or is labelled
for a SELinux domain trainsition upon execution.
But in case anyone has any reason to do that, we should follow good
security practices and not exec whatever is set in the environment.
We want to support large number of routes. Reduce the number
of copies, by adding internal accessor functions.
Also, work around a complaint from coverity:
46. NetworkManager-1.9.2/libnm-core/nm-utils.c:1987:
dereference: Dereferencing a null pointer "names".
nmc_read_connection_properties() iterates over the input arguments, and
completes the connection.
Initially, the type is not yet known, in that case, we should not wrongly
assume that this is a generic connection. Later, when the type is specified,
con_settings() will return the correct settings.
Previously, this would wrongly add a [generic] section:
$ nmcli connection add type ethernet ifname eth1 con-name ethie autoconnect no ipv4.method auto ethernet.cloned-mac-address random
With the fix, it still works to specify the type later:
$ nmcli connection add ifname eth1 con-name ethie autoconnect no ipv4.method auto type ethernet
but it doesn't work, to specify the type after type-specific options:
$ nmcli connection add ifname eth1 con-name ethie autoconnect no ipv4.method auto ethernet.cloned-mac-address random type ethernet
Error: invalid or not allowed setting 'ethernet': 'ethernet' not among [connection, ipv4, ipv6, proxy].
The patch doesn't change the latter limitation.

Replace the usage of g_str_hash() with our own nm_str_hash().
GLib's g_str_hash() uses djb2 hashing function, just like we
do at the moment. The only difference is, that we use a diffrent
seed value.
Note, that we initialize the hash seed with random data (by calling
getrandom() or reading /dev/urandom). That is a change compared to
before.
This change of the hashing function and accessing the random pool
might be undesired for libnm/libnm-core. Hence, the change is not
done there as it possibly changes behavior for public API. Maybe
we should do that later though.
At this point, there isn't much of a change. This patch becomes
interesting, if we decide to use a different hashing algorithm.
In a later commit we'll add a new generic client function used by
nmcli and nmtui. nm-client-utils.c seems the right place for it, so
move the file to the base library that is used by both clients.
While at it, also put in that file some functions that will be needed
by nmtui.
'nmcli device wifi connect' only supports WEP and WPA-PSK at the
moment, but not WPA-EAP. If the AP supports both WPA-PSK and WPA-EAP,
nmcli doesn't add the PSK to the connection, causing a connection
failure. Fix this.

As far as NetworkManager is concerned, the "connection.id" (also called
"con-name" in nmcli) is a pretty name and does not need to be unique.
UI components usually show the "connection.id" instead of the
"connection.uuid" identifier. It is hence likely, that the user
would not intentionally re-use the same name for multiple connection
profiles.
Print a warning to stderr when the user adds such a connection.
This only affects `nmcli connection add` and `nmcli connection import`,
but not `nmcli connection clone` and not interactive edit mode.

Currently nmcli considers the state of the device associated to a
connection to determine the success of an activation; for VPNs the
device is the parent interface on which the VPN is established.
This means that VPNs on bond/bridge/team interfaces are reported as
connected immediately because of the special handling of master
devices state in check_activated().
The parent device state is not meaningful for VPNs, so don't track it.
Since properties are asked only when the connection has the related
setting, ensure that the connection type is set early so that the base
type gets added to the connection before evaluating other settings.
After NMSettingConnection properties, ask properties for the base
setting and then all other settings.
The INT signal can arrive after a new line has been processed in
nmc_readline_helper(). In such case, the handler gets uninstalled by
readline_cb() and nmc_seen_sigint() returns TRUE. However it's an
error to call rl_callback_read_char() without handler, don't do it.
