* Ensure that RTF_LOCAL route entries always stay UP.mpi2015-09-252-3/+9
| | | | | | | | | | | Local route entries, being now attached to their corresponding interface, are susceptible to be brought DOWN when a link state change occurs. When this happens locally configured addresses are no longer reachable. So keep the previous (original) behavior by forcing such route entries to always be UP. ok sthen@, claudio@

| | | | | | | | | | | | | | | reclaiming to the PDU and marker input routines. m_pullup may return a pointer to the newly allocated mbuf. In this case m_freem is called by the trunk_input, not by the proto specific code and pointer to the mbuf is not passed by reference. Therefore m_freem will either be called on the middle element of the chain (when the m_pullup call succeeds) or on the stale pointer (when it frees the chain in the failure case). Fortunately we should never hit this case as the receive path uniformly uses contiguous chunks of memory. Verified with and ok blambert, ok mpi

| | | | | | | | | | | | | | | | | commit 48f8f36a6c8018c2b36ea207aaf68ef5326c5075 on the linux-3.14.y branch of the linux-stable tree). This brings preliminary support for the GPU on Intel's Broadwell CPUs. Don't expect these to work perfectly yet. There are some remaining issues with older hardware as well, but no significant regressions have been uncovered. This also updates some of drm core code. The radeondrm code remains based on Linux 3.8 with some minimal canges to adjust to changes in the core drm APIs. Joint effort with jsg@, who did the initial update of the relevant drm core bits. Committing this early to make sure it gets more testing and make it possible for others to help getting the remaining wrinkles straightened out.

* Serialize trunk changes with input handler insertion and removal.mikeb2015-09-231-7/+12
| | | | | | | | | | | | | | | | | | | | | This moves around calls to if_ih_insert and if_ih_remove to ensure that we either have completed port initialization or are going to tear the port configuration down and don't want any input processes to get hold of the port. When trunk_port_destroy is called from the ioctl this would wait for all input processes to finish and release their references to be able to disestablish the input handler and ensure full control of the port. When switching trunkproto it is required for the ioctl context to be able to touch all trunk ports and the protocol (tr_psc). The easiest way do this is to disestablish all input handlers (while making sure they all complete) and then reestablish them after the trunk reconfiguration is completed. This avoids getting trunk a separate locking protocol of its own. ok mpi, suggested by and ok dlg

| | | | | | | | | | | | | | and we want to limit the number of different places where we access trunk port pointers. trunk_watchdog should be never called as we don't set up it's if_timer and trunk_port_watchdog just calls the if_watchdog from the underlying interface. It's possible that this is no longer needed due to if_slowtimo/ if_watchdog changes done earlier. ok mpi
