Current versions of libnl3 use nl_addr_get_len() instead of
nl_addr_get_prefixlen() to determine the default route. Therefore we're
employing a workaround that sets the address length to zero for default
routes.
Unfortunately this workaround causes nl_addr to have wrong address size,
which in turn requires another workaround in init_ip4_route() as well as
init_ip6_route() to cope with the inconsistency.
Even though this solution is very very ugly, we didn't find a better
one. Not calling rtnl_route_set_dst() didn't solve the problem. Thomas
Graf promised to fix the libnl problem upstream. When bumping dependency
to a version that does this correctly, the workarounds can be removed.
With the move of udev logic into the Linux platform class, the
link-added signals are asynchronous, that is they are not emitted
during the call to nm_platform_*_add(), but after that call has
returned. The Fake implementation still emitted them synchronously,
which broke the testcases. Convert the Fake implementation to emit
link-added signals asynchronously and update the testcases to handle
this.
Since the platform started using udev for link-added signals, we need
to run the glib mainloop to wait for the udev signals to come in,
instead of expecting them to be emitted immediately.
The whole point of having type_name separate from type was so that
unknown devices could still have known device types. But I wrote it
wrong and then didn't notice until explicitly vxlan support got
removed and vxlans started showing up as "unknown".
nm_platform_query_devices() was just looking in the link_cache,
completely ignoring udev, which means that the link list wasn't
filtered for things NM wants to ignore.
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.
This requires a very recent kernel to even compile, and the kernel
code is still rapidly changing (eg, adding IPv6 support). So take it
out for now, until it stabilizes.
This reverts commit 7f0f04d106.
Rather than having a bunch of udev-based tests, use
nm_platform_link_get_type() to categorize devices.
Incomplete, as NMPlatform still categorizes most hardware types as
"ETHERNET", so we still need udev-based tests for those.

Some devices aren't expected to support carrier detection, so there's
no reason to have NMDevice log about it. Move that message into
NMDeviceEthernet, where failure to support carrier-detect really is
worth mentioning.
Also, make NMDeviceEthernet use NMPlatform for carrier-detection
detection (and move the MII carrier-detect-support check from
NMDeviceEthernet into NMLinuxPlatform).
Finally, have NMDeviceGeneric actually check whether the device
supports carrier detect, rather than just always assuming it doesn't.
This will help to store more link attributes in NMFakePlatform link
array than in public NMPlatformLink array. Some of the future
attributes will not be part of the NMPlatform API.
Although having different parts of NM in different subdirectories
keeps the source tree neat, it has made the build messy, particularly
because of cross-dependencies between the subdirs.
Reorganize to build all of the pieces of the NetworkManager binary
from src/Makefile, and only use recursive make for test programs,
helper binaries, and plugins.
As part of this, get rid of all the per-directory convenience
libraries, and switch to building a single top-level
libNetworkManager.la, containing everything except main.c, which all
of the test programs can then link against.
