mptcpd 0.6 - Mptcpd now supports versions of the Embedded Linux Library (ELL) greater than 0.33. - Plugins should use the new MPTCPD_PLUGIN_DEFINE() preprocessor macro instead of L_PLUGIN_DEFINE(). - A pointer to the mptcpd path manager object, i.e. struct mptcpd *pm, is now passed to the plugin init and exit functions. This allows plugins to potentially perform mptcpd path manager related operations during initialization and finalization. - Support for the MPTCP netlink path manager in the upstream Linux kernel is now available. A new set of path management command functions corresponding to those available in the kernel netlink path management API has been added to the `<mptcpd/path_manager.h>' header. The new functions allow plugins to retrieve IP address information, flush addresses, and modify MPTCP resource limits. - The mptcpd_pm_add_addr() (formerly mptcpd_pm_send_addr()) and mptcpd_pm_remove_addr() function parameters have been modified in order to support both the upstream and multipath-tcp.org kernels. - Mptcpd path management command functions declared in `<mptcpd/path_manager.h>' now return zero on success and -1 or an errno on failure instead of a bool. - A MPTCP address ID manager "mptcpd_idm" interface was introduced that mptcpd plugins may leverage to map an IP address to a MPTCP address ID, as well as to track used and unused IDs. The interface is defined in the new `<mptcpd/id_manager.h>' header. - A new address advertising plugin, "addr_adv", has been added. It simply triggers a MPTCP ADD_ADDR when a new IP address is detected by the mptcpd network monitor. Similarly, a MPTCP REMOVE_ADDR is triggered when an IP address is no longer available. - MPTCP netlink command error message logging was improved to be more descriptive when possible.
