2015-05-09tipc: send explicit not supported error in nl compatRichard Alpe1-1/+1
The legacy netlink API treated EPERM (permission denied) as "operation not supported".

2015-05-09tipc: fix default link prop regression in nl compatRichard Alpe1-22/+113
Default link properties can be set for media or bearer. This functionality was missed when introducing the NL compatibility layer. This patch implements this functionality in the compat netlink layer. It works the same way as it did in the old API. We search for media and bearers matching the "link name". If we find a matching media or bearer the link tolerance, priority or window is used as default for new links on that media or bearer.

2015-02-10tipc: convert legacy nl bearer enable/disable to nl compatRichard Alpe1-0/+144
Introduce a framework for transcoding legacy nl action into actions (.doit) calls from the new nl API. This is done by converting the incoming TLV data into netlink data with nested netlink attributes. Unfortunately due to the randomness of the legacy API we can't do this generically so each legacy netlink command requires a specific transcoding recipe. In this case for bearer enable and bearer disable. Convert TIPC_CMD_ENABLE_BEARER and TIPC_CMD_DISABLE_BEARER into doit compat calls.

2015-02-10tipc: convert legacy nl bearer dump to nl compatRichard Alpe1-1/+273
Introduce a framework for dumping netlink data from the new netlink API and formatting it to the old legacy API format. This is done by looping the dump data and calling a format handler for each entity, in this case a bearer. We dump until either all data is dumped or we reach the limited buffer size of the legacy API. Remember, the legacy API doesn't scale. In this commit we convert TIPC_CMD_GET_BEARER_NAMES to use the compat layer.
