2017-02-10ndp: deregister netlink event socket for non recoverable errorsHans Dedecker
Deregister netlink event socket in case of error different from ENOBUFS or failure to set netlink rx buffer size Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>
2017-02-09ndp: harden netlink event socket error handlingHans Dedecker
Start with a netlink receive buffersize of 130k for the netlink event socket; double the netlink receive buffer size in case an ENOBUFS is reported. Also align function naming and its parameters. Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>
2017-02-09ndp: close proc file descriptor also during error handlingHans Dedecker

2017-02-09npd: rework IPv6 relay logic (FS#396)Hans Dedecker
Rework the IPv6 relay logic to make it more robust by making use of libnltiny to process netlink messages. At the same time reimplement the IPv6 relay finite state machine to make the relay logic less error prone Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>
2017-01-31odhcpd: properly handle netlink messages (FS#388)Hans Dedecker
Use libnl-tiny to construct and process netlink messages when manipulating IPv6 routes and fetching IPv6 addresses. This fixes lingering netlink error messages on the netlink socket in case route deletion failed causing fetching of IPv6 addresses to be aborted and odhcpd faultly assuming no IPv6 addresses being present on the interface.
2017-01-23treewide: rework prio of syslog messagesHans Dedecker
Rework prio of syslog messages allowing to filter out the relevant messages by setting the correct log level Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>

ia_reconf is only set but nowhere used; so let's remove it ... Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>

2017-01-21treewide: use RELAYD_MAX_ADDRS as address array sizeHans Dedecker

2017-01-21ndp: don't scan netlink attributes in case of netlink route eventHans Dedecker
In case a netlink route event is received for a default route netlink data attributes were faulty processed as neigbor netlink data. Fix this by not processing any netlink attribute for any route event. Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>

As described in RFC3315 §15 any solicit, confirm, rebind or information request message is discarded if the destination address is unicast Likewise any request (§18.2.1), renew (§18.2.3), release (§18.2.6) or decline (§18.2.7) message is discarded and the server replies with the status code use multicast.
