* More fixes for using IPv6 addresses with RDMA:Hans Petter Selasky2016-04-225-21/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Added check that the SCOPE ID is only restored for IPv6 linklocal addresses. - Changes made by r237263 in the "cma_bind_addr()" function did not check if the socket address was of type IPv6 and used the IPv4 socket address for IPv6 addresses. This caused the function to fail. Fixed this. - In the "rdma_gid2ip()" function and some other places the "sin6_len" and "sin6_scope_id" fields were not set for IPv6 socket addresses. Fixed this. - The scope ID is not stored as part of the GID entries and must be passed as an argument to "rdma_gid2ip()". - Added new method to "struct ib_device" which returns a pointer to the network interface which belongs to the given infiniband device. This is needed to be able to get the scope ID for IPv6 addresses via the associated ethernet interface. - Added convenience function, "rdma_get_ipv6_scope_id()", to get the scope ID for IPv6 addresses. - Implemented new "get_netdev" method for mlx4ib. Other IB controller drivers which want to support IPv6 addresses needs to implement this aswell. - Bumped the FreeBSD version due to changing "struct ib_device".

* Fix for using IPv6 addresses with RDMA:Hans Petter Selasky2016-04-211-39/+108
| | | | | | | | | | | | | | | | | IPv6 addresses has a scope ID which sometimes is stored in the "sin6_scope_id" field of "struct sockaddr_in6" and sometimes as part of the IPv6 address itself depending on the context. If the scope ID is not in the expected location, the IPv6 address lookups in the so-called GID table will fail. Some code factoring has been made to achieve a clean exit of the "addr_resolve" function via a common "done" label.

* Fix for iWARP servers that listen on INADDR_ANY.Navdeep Parhar2016-01-222-6/+363
| | | | | | | | | | | | | | | | | | | The iWARP Connection Manager (CM) on FreeBSD creates a TCP socket to represent an iWARP endpoint when the connection is over TCP. For servers the current approach is to invoke create_listen callback for each iWARP RNIC registered with the CM. This doesn't work too well for INADDR_ANY because a listen on any TCP socket already notifies all hardware TOEs/RNICs of the new listener. This patch fixes the server side of things for FreeBSD. We've tried to keep all these modifications in the iWARP/TCP specific parts of the OFED infrastructure as much as possible.

* Finish r275196: do not dereference rtentry in if_output() routines.Alexander V. Chernikov2016-01-091-6/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The only piece of information that is required is rt_flags subset. In particular, if_loop() requires RTF_REJECT and RTF_BLACKHOLE flags to check if this particular mbuf needs to be dropped (and what error should be returned). Note that if_loop() will always return EHOSTUNREACH for "reject" routes regardless of RTF_HOST flag existence. This is due to upcoming routing changes where RTF_HOST value won't be available as lookup result. All other functions require RTF_GATEWAY flag to check if they need to return EHOSTUNREACH instead of EHOSTDOWN error. There are 11 places where non-zero 'struct route' is passed to if_output(). For most of the callers (forwarding, bpf, arp) does not care about exact error value. In fact, the only place where this result is propagated is ip_output(). (ip6_output() passes NULL route to nd6_output_ifp()). Given that, add 3 new 'struct route' flags (RT_REJECT, RT_BLACKHOLE and RT_IS_GW) and inline function (rt_update_ro_flags()) to copy necessary rte flags to ro_flags. Call this function in ip_output() after looking up/ verifying rte. Reviewed by: ae Notes: svn path=/head/; revision=293544

| | | | | | | | | | | | | sbappendstream() does. Although, M_NOTREADY may appear only on SOCK_STREAM sockets, due to sendfile(2) supporting only the latter, there is a corner case of AF_UNIX/SOCK_STREAM socket, that still uses records for the sake of control data, albeit being stream socket. Provide private version of m_clrprotoflags(), which understands PRUS_NOTREADY, similar to m_demote(). Notes: svn path=/head/; revision=293432
* Implement interface link header precomputation API.Alexander V. Chernikov2015-12-311-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add if_requestencap() interface method which is capable of calculating various link headers for given interface. Right now there is support for INET/INET6/ARP llheader calculation (IFENCAP_LL type request). Other types are planned to support more complex calculation (L2 multipath lagg nexthops, tunnel encap nexthops, etc..). Reshape 'struct route' to be able to pass additional data (with is length) to prepend to mbuf. These two changes permits routing code to pass pre-calculated nexthop data (like L2 header for route w/gateway) down to the stack eliminating the need for other lookups. It also brings us closer to more complex scenarios like transparently handling MPLS nexthops and tunnel interfaces. Last, but not least, it removes layering violation introduced by flowtable code (ro_lle) and simplifies handling of existing if_output consumers. ARP/ND changes: Make arp/ndp stack pre-calculate link header upon installing/updating lle record. Interface link address change are handled by re-calculating headers for all lles based on if_lladdr event. After these changes, arpresolve()/nd6_resolve() returns full pre-calculated header for supported interfaces thus simplifying if_output(). Move these lookups to separate ether_resolve_addr() function which ether returs error or fully-prepared link header. Add <arp|nd6_>resolve_addr() compat versions to return link addresses instead of pre-calculated data. BPF changes: Raw bpf writes occupied _two_ cases: AF_UNSPEC and pseudo_AF_HDRCMPLT. Despite the naming, both of there have ther header "complete". The only difference is that interface source mac has to be filled by OS for AF_UNSPEC (controlled via BIOCGHDRCMPLT). This logic has to stay inside BPF and not pollute if_output() routines. Convert BPF to pass prepend data via new 'struct route' mechanism. Note that it does not change non-optimized if_output(): ro_prepend handling is purely optional. Side note: hackish pseudo_AF_HDRCMPLT is supported for ethernet and FDDI. It is not needed for ethernet anymore. The only remaining FDDI user is dev/pdq mostly untouched since 2007. FDDI support was eliminated from OpenBSD in 2013 (sys/net/if_fddisubr.c rev 1.65). Flowtable changes: Flowtable violates layering by saving (and not correctly managing) rtes/lles. Instead of passing lle pointer, pass pointer to pre-calculated header data from that lle.

* Simplify the way of attaching IPv6 link-layer header.Alexander V. Chernikov2015-09-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem description: How do we currently perform layer 2 resolution and header imposition: For IPv4 we have the following chain: ip_output() -> (ether|atm|whatever)_output() -> arpresolve() Lookup is done in proper place (link-layer output routine) and it is possible to provide cached lle data. For IPv6 situation is more complex: ip6_output() -> nd6_output() -> nd6_output_ifp() -> (whatever)_output() -> nd6_storelladdr() We have ip6_ouput() which calls nd6_output() instead of link output routine. nd6_output() does the following: * checks if lle exists, creates it if needed (similar to arpresolve()) * performes lle state transitions (similar to arpresolve()) * calls nd6_output_ifp() which pushes packets to link output routine along with running SeND/MAC hooks regardless of lle state (e.g. works as run-hooks placeholder). After that, iface output routine like ether_output() calls nd6_storelladdr() which performs lle lookup once again. As a result, we perform lookup twice for each outgoing packet for most types of interfaces. We also need to maintain runtime-checked table of 'nd6-free' interfaces (see nd6_need_cache()). Fix this behavior by eliminating first ND lookup. To be more specific: * make all nd6_output() consumers use nd6_output_ifp() instead * rename nd6_output[_slow]() to nd6_resolve_[slow]() * convert nd6_resolve() and nd6_resolve_slow() to arpresolve() semantics, e.g. copy L2 address to buffer instead of pushing packet towards lower layers * Make all nd6_storelladdr() users use nd6_resolve() * eliminate nd6_storelladdr() The resulting callchain is the following: ip6_output() -> nd6_output_ifp() -> (whatever)_output() -> nd6_resolve() Error handling: Currently sending packet to non-existing la results in ip6_<output|forward> -> nd6_output() -> nd6_output _lle() which returns 0. In new scenario packet is propagated to <ether|whatever>_output() -> nd6_resolve() which will return EWOULDBLOCK, and that result will be converted to 0.
