2022-12-07classify: increase metadata from 16- to 32-bitsBenoît Ganne1-2/+2
The metadata in classifier entries is used to index a fib or a dpo in the acl nodes which can exceeds UINT16_MAX in large configurations. To maintain entries size and alignment, decrease next_index from 32- to 16-bits: next_index should not exceed 16-bits in VPP, as it is already shown by vlib_buffer_enqueue_to_next() or dpo_id_t.dpoi_next_node.

classify hash used to be stored as u64 in buffer metadata, use 32 bits instead: - on almost all our supported arch (x86 and arm64) we use crc32c intrinsics to compute the final hash: we really get a 32-bits hash - the hash itself is used to compute a 32-bits bucket index by masking upper bits: we always discard the higher 32-bits - this allows to increase the l2 classify buffer metadata padding such as it does not overlap with the ip fib_index metadata anymore. This overlap is an issue when using the 'set metadata' action in the ip ACL node which updates both fields Type: fix Change-Id: I5d35bdae97b96c3cae534e859b63950fb500ff50 Signed-off-by: Benoît Ganne <bganne@cisco.com>

2020-12-15classify: add pcap/trace classfier mgmt API callsJon Loeliger1-171/+234
Add lookup/get/set API calls to manage both PCAP and Trace filtering Classifier tables. The "lookup" call may be used to identify a Classifier table within a chain of tables taht matches a particular mask vector. For efficiency, this call should be used to determine to which table a match vector should be added. The "get" calls return the first table within a chain (either a PCAP or the Trace) set of tables. The "set" call may be used to add a new table to one such chain. If the "sort_masks" flag is set, the tables within the chain are ordered such that the most-specific mask is first, and the least-specific mask is last. A call that "sets" a chain to ~0 will delete and free all the tables with a chain. The PCAP filters are per-interface, with "local0", (that is, sw_if_index == 0) holding the system-wide PCAP filter. The Classifier used a reference-counted "set" for each PCAP or trace filter that it stored. The ref counts were not used, and the vector of tables was only used temporarily to establish a sorted order for tables based on masks. None of that complexity was actually warranted, and where it was used, the same could be achieved more simply.

2020-11-10classify: fix classify filter trace del cli processingJon Loeliger1-35/+49
When a 'del' is used to delete a classify table, only the mask is needed to locate the table. Any match vector is unneeded. The tests failed to notice this, but if the test is run by hand in vppctl, it issues a parse error. Fix the test so that it doesn't supply irrelevant data. Fix the CLI processing to read always complete newline terminated line of input instead. This allows unneeded CLI parameters to be ignored. It also necessitated fixing a trace test which had then erroneously split a single CLI command over multiple lines. While in the area, fix a latent bug on table matching where a test for compatible mask vector sizes were not matching impedance properly (byte vs ux32x4).

Classifier data structures assume the contiguous chunk of memory within the heap. Default heap flags for dlmalloc allow for heap growth. When that happens, the memory becomes discontiguous. This results in symptoms that are more cryptic than necessary. Disabling the expand makes the session allocation behavior of the classifier the same for dlmalloc as for the legacy allocator.

2018-07-18Add config option to use dlmalloc instead of mheapDave Barach1-0/+8
Configure w/ --enable-dlmalloc, see .../build-data/platforms/vpp.mk src/vppinfra/dlmalloc.[ch] are slightly modified versions of the well-known Doug Lea malloc. Main advantage: dlmalloc mspaces have no inherent size limit. Change-Id: I19b3f43f3c65bcfb82c1a265a97922d01912446e Signed-off-by: Dave Barach <dave@barachs.net>
2018-02-07classifier-based ACL: refactor + add output ACLAndrew Yourtchenko1-1/+1
For implementation of MACIP ACLs enhancement (VPP-1088), an outbound classifier-based ACL would be needed. There was an existing incomplete code for outbound ACLs, it looked almost exact copy of input ACLs, minus the various enhancements, trying to sync that code seemed error-prone and cumbersome to maintain in the longer run. This change refactors the input+output ACLs processing into a unified routine (thus any changes will have effect on both), and also adds the API to set the output interface ACL, with the same format and semantics as the existing input one (except working on output ACL of course). WARNING: IP outbound ACL in L3 mode clobbers the ip.* fields in the vnet_buffer_opaque_t, since the code is using l2_classify.* The net_buffer (p0)->ip.save_rewrite_length is rescued into l2_classify.pad.l2_len, and used to rewind the header in case of drop, so that ipX_drop prints something sensible.

2017-11-10add classify session action set-sr-policy-indexGabriel Ganne1-1/+9
This allows to use the classifier to steer source routing packets instead of using the "sr steer" command. This way we can steer on anything instead of only the dst ip address. test: * add add_node_next function to the VppPapiProvider class. * add simple test scenario using the classifier to steer packets with dest ip addr == a7::/8 to the source routing insert node. * use new interface indexes (3,4) instead of (0,1) to prevent a cleanup conflict with the other tests which attach a specific fib to the interface. The test creates interfaces sepsrated from the other tests to prevent a conflict in the cleaning of the ip6 fib index 1 which causes vpp not to be able to find a default route on this table.
