* Fix parsing issue with split messagesThomas Gschwantner2019-12-111-16/+17
| | | | | | | Previously this would trigger a BUG_ON() since the calculation of length & offset was wrong since we added the previous part of the buffer (req->buf) in parse_request(). This meant handle_request() couldn't know how much bytes where actually left in the buffer or their offset.
* Fixup client, including a lot of refactoringThomas Gschwantner2019-12-111-8/+0

* Extract all RTNETLINK code into ipm.{c,h}Thomas Gschwantner2019-12-111-67/+0

* Serialize/deserialize messages into a structThomas Gschwantner2019-12-111-193/+196
| | | | | | Instead of a list of attributes, parse messages into a proper struct to avoid duplicating code in the server/client for handling this list, as well as making parsing nicer in general.

* Implement lease expirationThomas Gschwantner2019-07-181-1/+0

* Use epoll() instead of poll()Thomas Gschwantner2019-06-141-28/+23
| | | | | This enables us to later use the timeout parameter of epoll_wait() to timely remove expired leases.

* Add BUG() and BUG_ON()Thomas Gschwantner2019-06-021-1/+1

Send response messages. Extend protocol to include lease start and lease time, errno and errmsg. Move common code to common.[ch].
