C casts unconditionally force the type, and as such they don't
necessarily improve type safety, but rather overcome restrictions
from the compiler when necessary.
Casting a void pointer is unnecessary (in C), it does not make the
code more readable nor more safe. In particular for g_object_new(),
which is known to return a void pointer of the right type.
Drop such casts.
sed 's/([A-Za-z_0-9]\+ *\* *) *g_object_new/g_object_new/g' $(git grep -l g_object_new) -i
./contrib/scripts/nm-code-format-container.sh
Run:
./contrib/scripts/nm-code-format.sh -i
./contrib/scripts/nm-code-format.sh -i
Yes, it needs to run twice because the first run doesn't yet produce the
final result.

For simple matches like match.interface-name, match.driver, and
match.path, arguably what we had was fine. There each element
(like "eth*") is a wildcard for a single name (like "eth1").
However, for match.kernel-command-line, the elements match individual
command line options, so we should have more flexibility of whether
a parameter is optional or mandatory. Extend the syntax for that.
- the elements can now be prefixed by either '|' or '&'. This makes
optional or mandatory elements, respectively. The entire match
evaluates to true if all mandatory elements match (if any) and
at least one of the optional elements (if any).
As before, if neither '|' nor '&' is specified, then the element
is optional (that means, "foo" is the same as "|foo").
- the exclamation mark is still used to invert the match. If used
alone (like "!foo") it is a shortcut for defining a mandatory match
("&!foo").
- the backslash can now be used to escape the special characters
above. Basically, the special characters ('|', '&', '!') are
stripped from the start of the element. If what is left afterwards
is a backslash, it also gets stripped and the remainder is the
pattern. For example, "\\&foo" has the pattern "&foo" where
'&' is no longer treated specially. This special handling of
the backslash is only done at the beginning of the element (after
the optional special characters). The remaining string is part
of the pattern, where backslashes might have their own meaning.
This change is mostly backward compatible, except for existing matches
that started with one of the special characters '|', '&', '!', and '\\'.

The API does not allow to distinguish between an unset (NULL) or empty
strv array. For example, nm_setting_match_get_paths() never returns
%NULL, but returns an empty strv array.
On the other hand, the GObject properties of type G_TYPE_STRV have a
default value of %NULL. That means, also the getter should map both
unset and empty to %NULL.
Note that this is a change in behavior w.r.t. 1.24.0 API, where
match.interface-name property would return an empty strv array.
Regrading the other API, this is no change because it is new API
and we will fix it before 1.26.0 release.
(cherry picked from commit 62263e706f)
Add a new "path" property to the match setting, which can be used to
restrict a connection to devices with a given hardware path. The new
property is a list of patterns that are matched against the ID_PATH
udev property of devices.
ID_PATH represents the topological persistent path of a device and
typically contains a subsystem string (pci, usb, platform, etc.) and a
subsystem-specific identifier. Some examples of paths are:
pci-0000:00:02.0
pci-0000:00:14.0-usb-0:5:1.0
platform-1c40000.ethernet
systemd-networkd also has a "Path=" option to match a device by udev
ID_PATH.
Add a new "driver" match option to nm-settings. It allows to disable a
network connection configuration if a pattern is found or is not found
in the device driver name.
Add a new "kernel-command-line" match option to nm-settings. It allows
to disable a network connection configuration if a pattern is found or
is not found in /proc/cmdline.
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.
Order the code in our common way. No other changes.
- ensure to include the main header first (directly after
"nm-default.h").
- reorder function definitions: get_property(), set_property(),
*_init(), *_new(), finalize(), *_class_init().
Add a new 'match' setting containing properties to match a connection
to devices. At the moment only the interface-name property is present
and, contrary to connection.interface-name, it allows the use of
wildcards.
