link_extract_type() would return the NMLinkType and a
@type_name string. If the type was unknown, this string
was rtnl_link_get_type() (IFLA_INFO_KIND).
Split up this behavior and treat those values independently.
link_extract_type() now only detects the NMLinkType. Most users
don't care about unknown types and can just use nm_link_type_to_string()
to get a string represenation.
Only nm_platform_link_get_type_name() (and NMDeviceGeneric:type_description)
cared about a more descriptive type. For that, modify link_get_type_name()
to return nm_link_type_to_string() if NMLinkType could be detected.
As fallback, return rtnl_link_get_type().
Also, rename the field NMPlatformLink:link_type to "kind". For now this
field is mostly unused. It will be used later when refactoring platform
caching.
Most nm_platform_*() functions operate on the platform
singleton nm_platform_get(). That made sense because the
NMPlatform instance was mainly to hook fake platform for
testing.
While the implicit argument saved some typing, I think explicit is
better. Especially, because NMPlatform could become a more usable
object then just a hook for testing.
With this change, NMPlatform instances can be used individually, not
only as a singleton instance.
Before this change, the constructor of NMLinuxPlatform could not
call any nm_platform_*() functions because the singleton was not
yet initialized. We could only instantiate an incomplete instance,
register it via nm_platform_setup(), and then complete initialization
via singleton->setup().
With this change, we can create and fully initialize NMPlatform instances
before/without setting them up them as singleton.
Also, currently there is no clear distinction between functions
that operate on the NMPlatform instance, and functions that can
be used stand-alone (e.g. nm_platform_ip4_address_to_string()).
The latter can not be mocked for testing. With this change, the
distinction becomes obvious. That is also useful because it becomes
clearer which functions make use of the platform cache and which not.
Inside nm-linux-platform.c, continue the pattern that the
self instance is named @platform. That makes sense because
its type is NMPlatform, and not NMLinuxPlatform what we
would expect from a paramter named @self.
This is a major diff that causes some pain when rebasing. Try
to rebase to the parent commit of this commit as a first step.
Then rebase on top of this commit using merge-strategy "ours".
config.h should be included from every .c file, and it should be
included before any other include. Fix that.
(As a side effect of how I did this, this also changes us to
consistently use "config.h" rather than <config.h>. To the extent that
it matters [which is not much], quotes are more correct anyway, since
we're talking about a file in our own build tree, not a system
include.)
Add a new enum NMPlatformGetRouteMode. This extends the existing
functions nm_platform_ip4_route_get_all() and nm_platform_ip6_route_get_all()
to return default routes only.

These are (most likely) only warnings and not severe bugs.
Some of these changes are mostly made to get a clean run of
Coverity without any warnings.

Most places except the tests don't want the default route when asking
the platform for all routes, so make that simpler by just adding a
parameter for including the default route or not.
Add a "parent" field to NMPlatformLink, giving the parent device
ifindex for devices that have a parent.
Make nm_platform_link_get_all() sort the links before returning them,
so that masters appear after all of their slaves, and parent devices
appear before their children.
Remove the second call to nm_platform_query_devices() from NMManager
since it is now guaranteed that an NMDeviceVLAN's parent NMDevice will
have been created before the NMDeviceVLAN.
Merge the net-subsystem-monitoring functionality of NMUdevManager into
NMLinuxPlatform (and kill NMUdevManager). NMLinuxPlatform now only
emits link-added signals after udev processes the device, and uses
udev attributes to further identify the device. NMManager now
identifies devices solely based on the NMLinkType provided by the
platform.
Add a new libnm-glib method to get the type description for a device,
and use it in nmcli. For most types, the type description is based on
the class name, but for NMDeviceGeneric, it comes from the
:type-description property.
Extend nm-platform to support IPv4 and IPv6 route management.
Route features:
* Retrieve the list of IPv4 and IPv6 routes
* Add/delete/lookup IPv4 and IPv6 routes
* Flush all non-linklocal routes
Extend nm-platform to support IPv4 and IPv6 address management.
Address features:
* Retrieve the list of IPv4 and IPv6 addresses
* Add/delete/lookup IPv4 and IPv6 addresses
* Flush all non-linklocal addresses
Create the new nm-platform framework and implement link (or interface)
management. The nm-platform serves as the point of contact between
the rest of NetworkManager and the operating system.
There are two backends for nm-platform:
* NMFakePlatform: Fake kernel backend for testing purposes
* NMLinuxPlatform: Linux kernel backend for actual use
A comprehensive testsuite is included and will be extended with new
feature additions. To enable the Linux part of the testsuite, use
--enable-tests=root configure options and run 'make check' as root.
Use --enable-code-coverage for code coverage support.
./autogen.sh --enable-tests=root --enable-code-coverage
make
make -C src/platform check-code-coverage
Link features:
* Retrieve the list of links
* Translate between indexes and names
* Discover device type
* Add/remove dummy interfaces (for testing)
