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.
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.
On Linux, the gateway attribute is not a key attribute and therefore is
not necessary for functions that just need to identify a route. This may
be revisited when porting to other platforms but for now I want to keep
things simple.
In some cases, callers don't need to distinguish, eg,
ip4-address-added from ip6-address-added, but just need to know what
device the event occurred on. Make this simpler by including the
ifindex as a separate explicit argument, allowing callers to just
ignore the struct part.
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)
