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>
2018-06-01session: improve disconnect handlingFlorin Coras4-12/+39
If the caller is the session owning thread or the main thread with a worker barrier sync (cli/api) add an event to the pending disconnects vector in the session node and entirely avoid using the event queue. Useful for bursts of disconnects (like an app detach). If disconnects come from a processes, be willing to retry enqueueing the disconnect to the event queue multiple times.

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).

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>
