Check IP length in ether_extract_headers(). For LRO with ix(4) it is necessary to detect ethernet padding. Extract ip_len and ip6_plen from the mbuf and provide it to the drivers. Add extended sanitity checks, like IP packet is shorter than TCP header. This prevents offloading to network hardware with bougus packets. Also iphlen of extracted headers contains header length for IPv4 and IPv6, to make code in drivers simpler. OK mglocker@

Analyse header layout in ether_extract_headers(). Several drivers need IPv4 header length and TCP offset for checksum offload, TSO and LRO. Accessing these fields directly caused crashes on sparc64 due to misaligned access. It cannot be guaranteed that IP and TCP header is 4 byte aligned in driver level. Also gcc 4.2.1 assumes that bit fields can be accessed with 32 bit load instructions. Use memcpy() in ether_extract_headers() to get the bits from IPv4 and TCP header and store the header length in struct ether_extracted. From there network drivers can esily use it without caring about alignment and bit shift. Do some sanity checks with the length values to prevent that invalid values from evil packets get stored into hardware registers. If check fails, clear the pointer to the header to hide it from the driver. Add debug prints that help to figure out the reason for bad packets and provide information when debugging drivers. OK mglocker@

add some helpers for working with ethernet addresses as uint64_t the main bits are ether_addr_to_e64 and ether_e64_to addr for loading an ethernet address into a uin64_t and visa versa. there's also some macros for testing if an address in a uint64_t is multicast, broadcast, anyaddr, or if it's an 802.1q reserved multicast group address. the reason for this functionality is once you have an ethernet address as a uint64_t, operations like compares, bit tests, and so on are fast and easy. tested on amd64 and sparc64

deprecate interface input handler lists, just use one input function. the interface input handler lists were originally set up to help us during the intial mpsafe network stack work. at the time not all the virtual ethernet interfaces (vlan, svlan, bridge, trunk, etc) were mpsafe, so we wanted a way to avoid them by default, and only take the kernel lock hit when they were specifically enabled on the interface. since then, they have been fixed up to be mpsafe. i could leave the list in place, but it has some semantic problems. because virtual interfaces filter packets based on the order they were attached to the parent interface, you can get packets taken away in surprising ways, especially when you reboot and netstart does something different to what you did by hand. by hardcoding the order that things like vlan and bridge get to look at packets, we can document the behaviour and get consistency. it also means we can get rid of a use of SRPs which were difficult to replace with SMRs. the interface input handler list is an SRPL, which we would like to deprecate. it turns out that you can sleep during stack processing, which you're not supposed to do with SRPs or SMRs, but SRPs are a lot more forgiving and it worked. lastly, it turns out that this code is faster than the input list handling, so lots of winning all around. special thanks to hrvoje popovski and aaron bieber for testing. this has been in snaps as part of a larger diff for over a week.

add code to coordinate how bridges attach to ethernet interfaces. this is the first step in refactoring how ethernet frames are demuxed by virtual interfaces, and also in deprecating interface input list handling. we now have drivers for three types of virtual bridges, bridge(4), switch(4), and tpmr(4), and it doesn't make sense for any of them to be enabled on the same "port" interfaces at the same time. currently you can add a port interface to multiple types of bridge, but which one gets to steal the packets depends on the order in which they were attached. this creates an ether_brport structure that holds an input function for the bridge, and optionally some per port state that the bridge can use. arpcom has a single pointer to one of these structs that will be used during normal ether_input processing to see if a packet should be passed to a bridge, and will be used instead of an if input handler. because it is a single pointer, it will make sure only one bridge of any type is attached to a port at any one time. this has been in snaps as part of a larger diff for over a week.

split ether_output into resolution, encapsulation, and output functions if if_output can be overridden on ethernet interfaces, it will allow things like vlan to do it's packet encapsulation during output before putting the packet directly on the underlying interface for output. this has two benefits. first, it can avoid having ether_output on pseudo interfaces recurse, which makes profiling of the network stack a lot clearer. secondly, and more importantly, it allows pseudo ethernet interface packet encapsulation to by run concurrently by the stack, rather than having packets unnecessarily serialied by an ifq. this diff just splits ether_output up, it doesnt have any interface take advantage of it yet. tweaks and ok claudio@

replace the use of ifqueues for most input queues serviced by netisr with niqueues. this change is so big because there's a lot of code that takes pointers to different input queues (eg, ether_input picks between ipv4, ipv6, pppoe, arp, and mpls input queues) and falls through to code to enqueue packets against the pointer. if i changed only one of the input queues id have to add sepearate code paths, one for ifqueues and one for niqueues in each of these places by flipping all these input queues at once i can keep the currently common code common. testing by mpi@ sthen@ and rafael zalamena ok mpi@ sthen@ claudio@ henning@

extend the if_ethersubr.c crc functions to support updating a running crc in addition to the existing "oneshot" mode and use them to replace ieee80211_crc_update() with the new ether_crc32_le_update(). Saves 1k kernel bss + some code. Mark the new ether_crc32_[lb]e_update functions as __pure for a ~25x speedup (on my i386 at least). feedback and ok damien@

pull post-4.4BSD change to sys/net/route.c from BSD/OS 4.2 (UCB copyrighted). have sys/net/route.c:rtrequest1(), which takes rt_addrinfo * as the argument. pass rt_addrinfo all the way down to rtrequest, and ifa->ifa_rtrequest. 3rd arg of ifa->ifa_rtrequest is now rt_addrinfo * instead of sockaddr * (almost noone is using it anyways). benefit: the follwoing command now works. previously we need two route(8) invocations, "add" then "change". # route add -inet6 default ::1 -ifp gif0 remove unsafe typecast in rtrequest(), from rtentry * to sockaddr *. it was introduced by 4.3BSD-reno and never corrected. XXX is eon_rtrequest() change correct regarding to 3rd arg? eon_rtrequest() and rtrequest() were incorrect since 4.3BSD-reno, so i do not have correct answer in the source code. someone with more clue about netiso-over-ip, please help.

as well, but you'll need KAME userland tools to play with IPv6 (will be
