nm_utils_enum_to_str() may also output numeric values if there is no
corresponding "nick" for the enum/flag value.
For enums the value is in decimal and for flags the value is hexadecimal
(with a "0x" prefix).
The same was already supported by nm_utils_enum_from_str() when reading
the value. However, previously, reading a flag would only support hex
numbers and reading a enum would only support decimal numbers.
Extend that, to allow passing numbers in any base. For nm_utils_enum_to_str()
also make sure to never output nicks that may be misinterpreted as
numbers.
It is not uncommon that a flags type has also the value 0 mapped,
for example to "unknown" or "none".
In that case, we should not return an empty string, but instead
that zero value.
Also, flags actually have an unsigned type. That isn't a real
problem to cast it to a signed int. But be more careful about
it and use unsigned while handling unsigned values and only
cast to int once.
These functions return static information, and don't require
a @setting argument. The list of options is interesting even
when having now setting instance at hand.
Document this to promise the user that passing %NULL is allowed.
It was allowed since when those functions were added.
There are very few places where we actually use floating point
or #include <math.h>.
Drop that library, although we very likely still get it as indirect
dependency (e.g. on my system it is still dragged in by libsystemd.so,
libudev.so and libnl-3.so).
NMVpnConnectionStateReason is no longer used and replaced by
NMActiveConnectionStateReason. However, the old enums should
stay in place as they were:
Otherwise:
#define NMVpnConnectionStateReason NMActiveConnectionStateReason
causes compiler warnings:
NMVpnConnectionStateReason x;
x = NM_VPN_CONNECTION_STATE_REASON_UNKNOWN; // -Wenum-conversion
if (x == NM_VPN_CONNECTION_STATE_REASON_NO_SECRETS) { } // -Wenum-compare
Similarly, a user who didn't upgrade shall continue to get the
old GType for NM_TYPE_VPN_CONNECTION_STATE_REASON.
In practice, old users will have no issues using the old enum
the places where it worked before.
The only use of the deprecated enum is in vpn_state_changed()
signal slot of NMVpnConnection. This makes the signal slot
itself deprecated. However, NMVpnConnection is an NMObject and commonly
created within libnm itself, not by the user. It is very unlikely that
a user of libnm subclassed NMVpnConnection and makes use of the
vpn_state_changed() signal slot. So, deprecate it without replacement.

It includes a reason code that makes it possible for the clients to be
more reasonable about error messages.
The reason code is essentially copied from the VPN, plus three more
reasons that were useful for non-VPN connections.
In practice, this should only matter when there are multiple
header files with the same name. That is something we try
to avoid already, by giving headers a distinct name.
When building NetworkManager itself, we clearly want to use
double-quotes for including our own headers.
But we also want to do that in our public headers. For example:
./a.c
#include <stdio.h>
#include <nm-1.h>
void main() {
printf ("INCLUDED %s/nm-2.h\n", SYMB);
}
./1/nm-1.h
#include <nm-2.h>
./1/nm-2.h
#define SYMB "1"
./2/nm-2.h
#define SYMB "2"
$ cc -I./2 -I./1 ./a.c
$ ./a.out
INCLUDED 2/nm-2.h
Exceptions to this are
- headers in "shared/nm-utils" that include <NetworkManager.h>. These
headers are copied into projects and hence used like headers owned by
those projects.

For IPv4 we support both the legacy and the new route file format. In
the legacy format, option are appended to the "ip route" command
arguments:
203.0.113.0/24 metric 3 via 198.51.100.1 dev eth2 cwnd 14 mtu lock 1500
This is backwards compatible with initscripts. In the new format, a
OPTIONSx= variable is added to represent the options in the same
format understood by iproute2:
ADDRESS0=203.0.113.0
NETMASK0=255.255.255.0
GATEWAY0=198.51.100.1
METRIC0=3
OPTIONS0="cwnd 14 mtu lock 1500"
initscripts do not support this variable at the moment (but the
changes needed to support it are trivial).
By default the new format is used, unless the route file is already in
the legacy format.
For IPv6 only the legacy format is supported, as before.
This adds definition of a set of known route option attributes to
libnm-core and helper functions.
nm_ip_route_attribute_validate() performs the validation of the
attribute type and, in case of a formatted string attribute, of its
content.
nm_ip_route_get_variant_attribute_spec() returns the attribute format
specifier to be passed to nm_utils_parse_variant_attributes(). Since
at the moment NMIPRoute is the only user of NMVariantAttributeSpec and
the type is opaque to users of the library, the struct is extended to
carry some other data useful for validation.
Various libnm objects (addresses, routes) carry an hash table of
attributes represented as GVariants indexed by name. Add common
routines to convert to and from a string representation.
To parse a string, a knowledge of the supported attributes (and their
types) is needed: we represent it as an opaque type
NMVariantAttributeSpec that callers must query to the library for the
specific object type and pass to the parse function.
Having a bridge-port/team-port setting for a connection that
has a different slave-type makes no sense. Such a configuration
shall be considered invalid, and be fixed by normalization.
Note that there is already a normalization the other way around,
when you omit the "slave-type" but a "master" and one(!) port-type
setting is present, the slave-type is automatically determined
based on the port-type.
The use of this is of course to modify an existing slave connection
to make it a non-slave. Then the invalid port settings should be
automatically removed.
Previously, ifcfg-rh writer would write the "BRIDGING_OPTS" setting
without a "BRIDGE". The reader would then (correctly) ignore the
bridge-port. Avoid that altogehter, by requiring the connection to
strictly verify.
A "vlan" setting can optionally have an ethernet setting.
However, ifcfg-rh reader always adds such a setting, because
well... Anyway, the result is that writing a VLAN setting
without ethernet section will yield a different result
on re-read.
Let's have normalization add the ethernet setting, so that
two we consistently have it present.
Add support for creating dummy devices. This commit adds a D-Bus
interface 'org.freedesktop.NetworkManager.Device.Dummy' which is used
primarily for determining the device type but does not carry any
properties.
The property can be used to tune the authentication timeout. It's
especially useful to speed up the failure in case the port doesn't
support 802.1X and make NM try a different, non-authenticated
connection.
The wpa_supplicant API supports to enable/disable each TLS version
individually, or leave it at the default. Currently, the default
means to enable a TLS version, thus, the only meaningful option
for the momemnt means to explicitly disable it.
In the future, supplicant may disable options by default, and
the inverse option can become interesting to configure
"tls_disable_tlsv1_0=0". When that happens, we can solve it by
adding another flag NM_SETTING_802_1X_AUTH_FLAGS_TLS_1_0_ENABLE.
Change the previous behavior of the NMSetting8021xAuthFlags.
Previously, when not specifying TLS_DISABLE_DEFAULT, all
options were unspecified. On the other hand, when specifying
a single TLS disable flag, all versions were explicitly enabled
or disabled.
Instead, change the meaning of the disable flags. When present,
it explicitly disables an option. But it does not explicitly enable
it.
- for nm_utils_enum_to_str(), whenever encounter a numeric value
that has no expression as enum/flag, encode the value numerically.
For enums, encode it as decimal. For flags, encode it as hexadecimal
(with 0x prefix).
Also check that an existing value_nick cannot be wrongly interpreted
as a integer, and if they would, encode them instead as integers only.
- Likewise, in nm_utils_enum_from_str() accept numerical values
and for nm_utils_enum_get_values() return enum nicks that look
like numeric values in their numeric form only.
- In nm_utils_enum_from_str(), don't use g_strsplit(), but clone the
string only once and manipulate it inplace.
- Accept '\n' and '\r' as additional delimiters for flags.
- For consistency, also return an err_token for enum types. If the caller
doesn't care about that, he should simply not pass the out-argument.
Unfortunately nm_utils_enum_to_str() doesn't allow to specify the
separator between enum values. Since the function is public API and
can't be modified now, add a new internal function which accepts the
separator as argument.
