allow ethernet interfaces to provide a custom if_output routine. this will be mostly useful for virtual interfaces like vlan and etherip, where they can bypass queueing on an ifq, and instead encapsulate in on multiple cpus concurrently and push the packet onto the next layer directly. ok visa@ |

Make kcov MP-safe. Calling the injected tracing function __sanitizer_cov_trace_pc() early in the boot process caused a subtle crash while booting the secondary CPU(s). On amd64, accessing curcpu during this period is not safe since its GSBASE register is yet not written. After the CPU has been booted curproc can also be NULL for a brief period of time before the idle thread tied to the same CPU has started. The two problems can simply be avoided by postponing access to curcpu and curproc until /dev/kcov has been opened at least once. The end goal here is to allow fuzzing of MP kernels, which already is in full swing. This work has gone through many iterations before settling on the least intrusive change; many thanks for visa@ for reviewing and providing valuable input. Issue originally reported by Greg Steuck on tech@ who also took the time to test all iterations and providing me access to a virtualised OpenBSD machine for easier testing. ok mpi@ visa@ |

Various cleanups: - Unify the two hooks by passing the same argument - Check for nullity before dereferencing `if_bridgeport', this will matter when we go MP - Use the same pattern to find a member in the ioctl path ok bluhm@, visa@ |
