next nodes Use the new frame-at-once functions vlib_get_buffers() and vlib_buffer_enqueue_to_next() to calculate the buffer pointers and to dispatch the packets after the processing. This simplifies the dataplane node processing loop. Change-Id: I454308f847aac76a199f8dd7490c1e176414bde7 Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>

2018-05-27acl-plugin: use clib_bihash_search_inline_2_40_8 rather than ↵Andrew Yourtchenko2-5/+3
clib_bihash_search_40_8 for session lookups Use inline version rather than calling the function, this gives slightly better performance. The straighforward diff uncovered an interesting problem: the stateful ACL IPv4 unit tests would fail for the "make test" but succeed in "make test-debug". Also, they would succeed even in "make test", if before calling the clib_bihash_search_inline_2_40_8 we would change the code to store the key in a temporary variable. Debugging revealed that the generated optimized code is not what one would expect: the zeroing of the u64s overlaying the memcpy into ipv4 value of ip46_address_t made the optimizer not notice the latter, and think that those fields should be always zero in the bihash, thus generating incorrect assembly for the bihash key comparison for the ipv4 nodes. Changing the zeroing to be non-overlapping by zeroing only the pad fields resulted in the optimizer generating the correct code and the tests pass.

2018-05-27VPP-1294: add missing feature arc constraintDave Barach6-52/+116
the ip4-dhcp-client-detect feature MUST run prior to nat44-out2in, or inbound dhcp broadcast packets will be dropped. Certain dhcp servers answer lease renewal dhcp-request packets with broadcast dhcp-acks, leading to unrecoverable lease loss. In detail, this constraint: VNET_FEATURE_INIT (ip4_snat_out2in, static) = { .arc_name = "ip4-unicast", .node_name = "nat44-out2in", .runs_after = VNET_FEATURES ("acl-plugin-in-ip4-fa"), }; doesn't get the job done: ip4-unicast: [17] nat44-out2in [23] ip4-dhcp-client-detect [26] ip4-not-enabled Add a proper constraint: VNET_FEATURE_INIT (ip4_snat_out2in, static) = { .arc_name = "ip4-unicast", .node_name = "nat44-out2in", .runs_after = VNET_FEATURES ("acl-plugin-in-ip4-fa", "ip4-dhcp-client-detect"), }; and the interface feature order is OK, at least in this regard: ip4-unicast: [17] ip4-dhcp-client-detect [18] nat44-out2in [26] ip4-not-enabled We need to carefully audit (especially) the ip4-unicast feature arc, which has [gasp] 37 features on it!

2018-05-26acl-plugin: create forward and return sessions in lieu of making a special ↵Andrew Yourtchenko5-121/+156
per-packet session key Using a separate session key has proven to be tricky for the following reasons: - it's a lot of storage to have what looks to be nearly identical to 5tuple, just maybe with some fields swapped - shuffling the fields from 5tuple adds to memory pressure - the fact that the fields do not coincide with the packet memory means for any staged processing we need to use up a lot of memory Thus, just add two entries into the bihash table pointing to the same session entry, so we could match the packets from either direction. With this we have the key layout of L3 info (which takes up the majority of space for IPv6 case) the same as in the packet, thus, opening up the possibility for other optimizations. Not having to create and store a separate session key should also give us a small performance win in itself. Also, add the routine to show the session bihash in a better way than a bunch of numbers. Alas, the memory usage in the bihash obviously doubles. Change-Id: I8fd2ed4714ad7fc447c4fa224d209bc0b736b371 Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>

2018-05-25bond: performance harvestingSteven9-161/+263
- hash is great. But it is a bit too slow for the DP. Use direct array indexing to quickly retrieve the slave interface. - the algorithm used by flow hash is great. But it is a bit too slow for the DP. Use l2_hash_hash() extracted from lb_hash.h which ECMP is using. It makes use of intrinsic crc32 instruction set. - shortcut modulo arithmetic when the operand is 2**x (where x up to 4) to avoid division instruction. - special case for link count == 1 in bond_tx_fn() - use clib_mem_unaligned to access data for the packet to avoid alignment error - Fix some typos for packet tracing.

2018-05-22acl-plugin: refactor to introduce multiarch dataplane functionsAndrew Yourtchenko6-1615/+2036
This commit splits the functions from fa_node.c into the pure dataplane node functions (which are multiarch-compiled), session management node functions (which are compiled only once), and session find/add/delete functions which are split out into the inlines. As part of the refactoring: - get rid of BV() macros in the affected chunk of code, rather use the explicit bihash function names. - add the magic trailer to the new files to ensure make checkstyle watches them. - move the bihash_template.c include for 40_8 bihash into acl.c Change-Id: I4d781e9ec4307ea84e92af93c09470ea2bd0c375 Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>
