2018-06-17acl-plugin: fix the high cpu usage caused by the connection cleanerAndrew Yourtchenko1-1/+2
The commit 4bc1796b346efd10f3fb19b176ff089179263a24 had incorrect calculation of the session lists minimal timeout, resulting in returned value of 0 which resulted in existing sessions constantly requeued, taking up the CPU. Fix this calculation. Change-Id: I9a789739f96a1f01522c68f91b0a02db2417837f Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>
2018-06-17acl-plugin: split (L3) and (L4/pkt) logic of creation of 5tuple structure, ↵Andrew Yourtchenko1-46/+70
optimize stores in the (l4/pkt) Having two pieces of code - one for now much simpler to recreate L3 info, one for a more difficult do build L4/pkt metadata allows more degrees of freedom for optimizations. Also, construct the metadata in local variables first before saving it into the memory structure, this fewer memory stores and they are better aligned, allowing to coalesce with subsequent reads if needed.

To enable NAT plugin endpoint dependent mode add following to statrup config: nat { endpoint-dependent } Enable endpoint dependent filtering and mapping for all sessions. Move some existing functionality such as service load balancing, twice nat, out2in-only static mappings and unknown protocol dynamic translations, which use endpoint dependent lookup hash tables before.

2018-06-14acl-plugin: VAT: add an option to load entire ACL from a ClassBench ruleset ↵Andrew Yourtchenko1-0/+190
file for testing Add a command "acl_add_replace_from_file" to VAT which can load a ruleset and add an ACL with it. There are a few options which augment the ACL being created: "permit+reflect" or "permit" alter the default action from deny on the ACEs created. "append-default-permit" adds an entry in the end with the "permit+reflect" if the default action has been changed to permit+reflect, or with a simple permit otherwise. This command is IPv4-only because the available datasets were IPv4-only. Change-Id: I26b9f33ecb6b59e051d1d9cbafedbc47e8203392 Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>

2018-06-13acl-plugin: change the src/dst L3 info in 5tuple struct to be always ↵Andrew Yourtchenko6-97/+156
contiguous with L4 data Using ip46_address_t was convenient from operational point of view but created some difficulties dealing with IPv4 addresses - the extra 3x of u32 padding are costly, and the "holes" mean we can not use the smaller key-value data structures for the lookup. This commit changes the 5tuple layout for the IPv4 case, such that the src/dst addresses directly precede the L4 information. That will allow to treat the same data within 40x8 key-value structure as a 16x8 key-value structure starting with 24 byte offset.

2018-06-02acl-plugin: multicore: session management fixesAndrew Yourtchenko6-151/+332
- implement a 1us purgatory for the session structures by adding a special connection list, where all connections about to be deleted go. - add per-list-head timeouts updated upon the list enqueue/dequeue for connection idle management - add a "unused" session list with list ID#0, which should never be used unless there is a logic error. Use this ID to initialize the sessions. - improve the maintainability of the session linked list structures by using symbolic bogus index name instead of ~0 - change the ordering of session creations - first reverse, then local. To minimize the potential for two workers competing for the same session in the corner case of the two packets on different workers creating the same logical session - reduce the maximum session count to keep the memory usage the same - add extra log/debug/trace to session cleaning logic - be more aggressive with cleaning up sessions - wind up the interrupts from the workers to themselves if there is more work to do Change-Id: I3aa1c91a925a08e83793467cb15bda178c21e426 Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>
2018-05-31dpdk: Decoupling the meaning of xd->device_index in dpdk_pluginRui Cai9-81/+99
Prior to the change, dpdk plugin assumes xd->device_index is used both as index for internal dpdk_main->devices array and DPDK port index to call into DPDK APIs. However, when running on top of Failsafe PMDs, DPDK port index range may no longer be contiguous (as noted: http://dpdk.org/ml/archives/dev/2018-March/092375.html for related changes in DPDK). Because this, dpdk plugin can no longer iterate through all available DPDK ports with a for 0->rte_eth_dev_count() loop and the assumption of device_index no longer holds. This is part of initial effort to enable vpp running over dpdk on failsafe PMD in Microsoft Azure(3/4).

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.

2018-05-26acl-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>

- 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.
