At a certain level, it's a dumb robot. Given an +incoming packet, search an ordered list of (mask, match) tables. If +the classifier finds a matching entry, take the indicated action. If +not, take a last-resort action. + +We use the MMX-unit to match or hash 16 octets at a time. For hardware +backward compatibility, the code does not [currently] use 256-bit +(32-octet) vector instructions. + +Effective use of the classifier centers around building table lists +which "hit" as soon as practicable. In many cases, established +sessions hit in the first table. In this mode of operation, the +classifier easily processes multiple MPPS / core - even with millions +of sessions in the data base. Searching 357 tables on a regular basis +will neatly solve the halting problem. + +==== Basic operation ==== + +The classifier mask-and-match operation proceeds as follows. Given a +starting classifier table index, lay hands on the indicated mask +vector. When building tables, we arrange for the mask to obey +mmx-unit (16-octet) alignment. + +We know that the first octet of packet data starts on a cache-line +boundary. Further, it's reasonably likely that folks won't want to use +the generalized classifier on the L2 header; preferring to decode the +Ethertype manually. That scheme makes it easy to select among ip4 / +ip6 / MPLS, etc. classifier table sets. + +A no-vlan-tag L2 header is 14 octets long. A typical ipv4 header +begins with the octets 0x4500: version=4, header_length=5, DSCP=0, +ECN=0. If one doesn't intend to classify on (DSCP, ECN) - the typical +case - we program the classifier to skip the first 16-octet vector. + +To classify untagged ipv4 packets on source address, we program the +classifier to skip one vector, and mask-and-match one vector. + +The basic match-and-match operation looks like this: + + switch (t->match_n_vectors) + { + case 1: + result = (data[0 + t->skip_n_vectors] & mask[0]) ^ key[0]; + break; + + case 2: + result = (data[0 + t->skip_n_vectors] & mask[0]) ^ key[0]; + result |= (data[1 + t->skip_n_vectors] & mask[1]) ^ key[1]; + break; + + + } + + result_mask = u32x4_zero_byte_mask (result); + if (result_mask == 0xffff) + return (v); + +Net of setup, it costs a couple of clock cycles to mask-and-match 16 +octets. + +At the risk of belaboring an obvious point, the control-plane +'''must''' pay attention to detail. When skipping one (or more) +vectors, masks and matches must reflect that decision. See +.../vnet/vnet/classify/vnet_classify.c:unformat_classify_[mask|match]. Note +that vec_validate (xxx, 13) creates a 14-element vector. + +==== Creating a classifier table ==== + +To create a new classifier table via the control-plane API, send a +"classify_add_del_table" message. The underlying action routine, +vnet_classify_add_del_table(...), is located in +.../vnet/vnet/classify/vnet_classify.c, and has the following +prototype: + + int vnet_classify_add_del_table (vnet_classify_main_t * cm, + u8 * mask, + u32 nbuckets, + u32 memory_size, + u32 skip, + u32 match, + u32 next_table_index, + u32 miss_next_index, + u32 * table_index, + int is_add) + +Pass cm = &vnet_classify_main if calling this routine directly. Mask, +skip(_n_vectors) and match(_n_vectors) are as described above. Mask +need not be aligned, but it must be match*16 octets in length. To +avoid having your head explode, be absolutely certain that '''only''' +the bits you intend to match on are set. + +The classifier uses thread-safe, no-reader-locking-required +bounded-index extensible hashing. Nbuckets is the [fixed] size of the +hash bucket vector. The algorithm works in constant time regardless of +hash collisions, but wastes space when the bucket array is too +small. A good rule of thumb: let nbuckets = approximate number of +entries expected. + +At a signficant cost in complexity, it would be possible to resize the +bucket array dynamically. We have no plans to implement that function. + +Each classifier table has its own clib mheap memory allocation +arena. To pick the memory_size parameter, note that each classifier +table entry needs 16*(1 + match_n_vectors) bytes. Within reason, aim a +bit high. Clib mheap memory uses o/s level virtual memory - not wired +or hugetlb memory - so it's best not to scrimp on size. + +The "next_table_index" parameter is as described: the pool index in +vnet_classify_main.tables of the next table to search. Code ~0 to +indicate the end of the table list. 0 is a valid table index! + +We often create classification tables in reverse order - +last-table-searched to first-table-searched - so we can easily set +this parameter. Of course, one can manually adjust the data structure +after-the-fact. + +Specific classifier client nodes - for example, +.../vnet/vnet/classify/ip_classify.c - interpret the "miss_next_index" +parameter as a vpp graph-node next index. When packet classification +fails to produce a match, ip_classify_inline sends packets to the +indicated disposition. A classifier application might program this +parameter to send packets which don't match an existing session to a +"first-sign-of-life, create-new-session" node. + +Finally, the is_add parameter indicates whether to add or delete the +indicated table. The delete case implicitly terminates all sessions +with extreme prejudice, by freeing the specified clib mheap. + +==== Creating a classifier session ==== + +To create a new classifier session via the control-plane API, send a +"classify_add_del_session" message. The underlying action routine, +vnet_classify_add_del_session(...), is located in +.../vnet/vnet/classify/vnet_classify.c, and has the following +prototype: + +int vnet_classify_add_del_session (vnet_classify_main_t * cm, + u32 table_index, + u8 * match, + u32 hit_next_index, + u32 opaque_index, + i32 advance, + int is_add) + +Pass cm = &vnet_classify_main if calling this routine directly. Table +index specifies the table which receives the new session / contains +the session to delete depending on is_add. + +Match is the key for the indicated session. It need not be aligned, +but it must be table->match_n_vectors*16 octets in length. As a +courtesy, vnet_classify_add_del_session applies the table's mask to +the stored key-value. In this way, one can create a session by passing +unmasked (packet_data + offset) as the "match" parameter, and end up +with unconfusing session keys. + +Specific classifier client nodes - for example, +.../vnet/vnet/classify/ip_classify.c - interpret the per-session +hit_next_index parameter as a vpp graph-node next index. When packet +classification produces a match, ip_classify_inline sends packets to +the indicated disposition. + +ip4/6_classify place the per-session opaque_index parameter into +vnet_buffer(b)->l2_classify.opaque_index; a slight misnomer, but +anyhow classifier applications can send session-hit packets to +specific graph nodes, with useful values in buffer metadata. Depending +on the required semantics, we send known-session traffic to a certain +node, with e.g. a session pool index in buffer metadata. It's totally +up to the control-plane and the specific use-case. + +Finally, nodes such as ip4/6-classify apply the advance parameter as a +[signed!] argument to vlib_buffer_advance(...); to "consume" a +networking layer. Example: if we classify incoming tunneled IP packets +by (inner) source/dest address and source/dest port, we might choose +to decapsulate and reencapsulate the inner packet. In such a case, +program the advance parameter to perform the tunnel decapsulation, and +program next_index to send traffic to a node which uses +e.g. opaque_index to output traffic on a specific tunnel interface. diff --git a/vnet/vnet/classify/input_acl.c b/vnet/vnet/classify/input_acl.c new file mode 100644 index 00000000000..2c533d1170c --- /dev/null +++ b/vnet/vnet/classify/input_acl.c @@ -0,0 +1,293 @@ +/* + * Copyright (c) 2015 Cisco and/or its affiliates. + * Licensed under the Apache License, Version 2.0 (the "License");

Expires January 5, 2015 [Page 2] + +Internet-Draft LISP Generic Protocol Extension July 2014 + + +1. Introduction + + LISP [RFC6830] defines an encapsulation format that carries IPv4 or + IPv6 (henceforth referred to as IP) packets in a LISP header and + outer UDP/IP transport. + + The LISP header does not specify the protocol being encapsulated and + therefore is currently limited to encapsulating only IP packet + payloads. Other protocols, most notably VXLAN [VXLAN] (which defines + a similar header format to LISP), are used to encapsulate L2 + protocols such as Ethernet. LISP [RFC6830] can be extended to + indicate the inner protocol, enabling the encapsulation of Ethernet, + IP or any other desired protocol all the while ensuring compatibility + with existing LISP [RFC6830] deployments. + + As LISP is deployed, there's also the need to provide increased + visibility and diagnostic capabilities within the overlay. + + This document describes extending LISP ([RFC6830]) via the following + changes: + + Next Protocol Bit (P bit): A reserved flag bit is allocated, and set + in the LISP-gpe header to indicate that a next protocol field is + present. + + OAM Flag Bit (O bit): A reserved flag bit is allocated, and set in + the LISP-gpe header, to indicate that the packet is an OAM packet. + + Version: Two reserved bits are allocated, and set in the LISP-gpe + header, to indicate LISP-gpe protocol version. + + Next protocol: An 8 bit next protocol field is present in the LISP- + gpe header. + + + + + + + + + + + + + + + + + + +Lewis, et al. Expires January 5, 2015 [Page 3] + +Internet-Draft LISP Generic Protocol Extension July 2014 + + +2. LISP Header Without Protocol Extensions + + As described in the introduction, the LISP header has no protocol + identifier that indicates the type of payload being carried by LISP. + Because of this, LISP is limited to an IP payload. Furthermore, the + LISP header has no mechanism to signal OAM packets. + + The LISP header contains flags (some defined, some reserved), a + Nonce/Map-version field and an instance ID/Locator-status-bit field. + The flags provide flexibility to define how the reserved bits can be + used to change the definition of the LISP header. + + + +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ + |N|L|E|V|I|flags| Nonce/Map-Version | + +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ + | Instance ID/Locator-Status-Bits | + +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ + + + Figure 1: LISP Header + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +Lewis, et al.

OAM bit MUST be set + to 0. The Next Protocol field SHOULD be 0x1 (IPv4) or 0x2 (IPv6). + The (legacy) LISP router will ignore the P bit and the protocol type + field. The (legacy) LISP router will treat the packet as a LISP + packet and inspect the first nibble of the payload to determine the + IP version. + + When the P bit is set, the N, E, and V bits MUST be set to zero.

This is called virtual reassembly because the fragments are not actually reassembled. Instead, some meta-data are kept about the first fragment and reused for subsequent fragments. + +Fragment caching and handling is not always necessary. It is performed when: +* An IPv4 fragment is received and the destination IPv4 address is shared. +* An IPv6 packet is received with an inner IPv4 fragment, the IPv4 source address is shared, and 'security-check fragments' is on. +* An IPv6 fragment is received. + +There are 3 dedicated nodes: +* ip4-map-reass +* ip6-map-ip4-reass +* ip6-map-ip6-reass + +ip4-map sends all fragments to ip4-map-reass. +ip6-map sends all inner-fragments to ip6-map-ip4-reass. +ip6-map sends all outer-fragments to ip6-map-ip6-reass. + +IPv4 (resp. IPv6) virtual reassembly makes use of a hash table in order to store IPv4 (resp. IPv6) reassembly structures. The hash-key is based on the IPv4-src:IPv4-dst:Frag-ID:Protocol tuple (resp. IPv6-src:IPv6-dst:Frag-ID tuple, as the protocol is IPv4-in-IPv6). Therefore, each packet reassembly makes use of exactly one reassembly structure. When such a structure is allocated, it is timestamped with the current time. Finally, those structures are capable of storing a limited number of buffer indexes. + +An IPv4 (resp. IPv6) reassembly structure can cache up to MAP_IP4_REASS_MAX_FRAGMENTS_PER_REASSEMBLY (resp. MAP_IP6_REASS_MAX_FRAGMENTS_PER_REASSEMBLY) buffers. Buffers are cached until the first fragment is received. + +#### Virtual Reassembly configuration + +IPv4 and IPv6 virtual reassembly support the following configuration: + map params reassembly [ip4 | ip6] [lifetime ] [pool-size ] [buffers ] [ht-ratio ] + +lifetime: + The time in milliseconds a reassembly structure is considered valid. The longer, the more reliable is reassembly, but the more likely it is to exhaust the pool of reassembly structures. IPv4 standard suggests a lifetime of 15 seconds. IPv6 specifies a lifetime of 60 people. Those values are not realistic for high-throughput cases. + +buffers: + The upper limit of buffers that are allowed to be cached. It can be used to protect against fragmentation attacks which would aim to exhaust the global buffers pool. + +pool-size: + The number of reassembly structures that can be allocated. As each structure can store a small fixed number of fragments, it also sets an upper-bound of 'pool-size * MAP_IPX_REASS_MAX_FRAGMENTS_PER_REASSEMBLY' buffers that can be cached in total. + +ht-ratio: + The amount of buckets in the hash-table is pool-size * ht-ratio. + + +Any time pool-size and ht-ratio is modified, the hash-table is destroyed and created again, which means all current state is lost. + + +##### Additional considerations + +Reassembly at high rate is expensive in terms of buffers. There is a trade-off between the lifetime and number of allocated buffers. Reducing the lifetime helps, but at the cost of loosing state for fragments that are wide appart. + +Let: +R be the packet rate at which fragments are received. +F be the number of fragments per packet. + +Assuming the first fragment is always received last. We should have: +buffers > lifetime * R / F * (F - 1) +pool-size > lifetime * R/F + +This is a worst case. Receiving the first fragment earlier helps reducing the number of required buffers. Also, an optimization is implemented (MAP_IP6_REASS_COUNT_BYTES and MAP_IP4_REASS_COUNT_BYTES) which counts the number of transmitted bytes and remembers the total number of bytes which should be transmitted based on the last fragment, and therefore helps reducing 'pool-size'. + +But the formula shows that it is challenging to forward a significant amount of fragmented packets at high rates. For instance, with a lifetime of 1 second, 5Mpps packet rate would require buffering up to 2.5 millions fragments. + +If you want to do that, be prepared to configure a lot of fragments. + + diff --git a/vnet/vnet/map/sixrd.c b/vnet/vnet/map/sixrd.c new file mode 100644 index 00000000000..26b4eea9a86 --- /dev/null +++ b/vnet/vnet/map/sixrd.c @@ -0,0 +1,355 @@ +/* + * Copyright (c) 2015 Cisco and/or its affiliates. + * Licensed under the Apache License, Version 2.0 (the "License");
