2017-06-19L2FWD:fix seq_num overwritten + validate l2fib entries when forwardingEyal Bari8-56/+99
l2_classify memeber table_index was overlaid over l2.l2fib_seq_num which over written when table_index gets initialized in l2_input_classify solved by overlaying both table_index and opaque_index as only one is used seperated l2fib seq num from l2_input configs for better handling of theoretical ABA issue where an entry for a deleted interface is considered valid by the ager because a different interface with same sw_if_index and seq_num was created before the ager got a chance to delete Change-Id: I7b0eeded971627406f1c80834d7e02c0ebe62136 Signed-off-by: Eyal Bari <ebari@cisco.com>

2017-06-19acl-plugin: bihash-based ACL lookupAndrew Yourtchenko10-10/+1572
Add a bihash-based ACL lookup mechanism and make it a new default. This changes the time required to lookup a 5-tuple match from O(total_N_entries) to O(total_N_mask_types), where "mask type" is an overall mask on the 5-tuple required to represent an ACE. For testing/comparison there is a temporary debug CLI "set acl-plugin use-hash-acl-matching {0|1}", which, when set to 0, makes the plugin use the "old" linear lookup, and when set to 1, makes it use the hash-based lookup. Based on the discussions on vpp-dev mailing list, prevent assigning the ACL index to an interface, when the ACL with that index is not defined, also prevent deleting an ACL if that ACL is applied. Also, for the easier debugging of the state, there are new debug CLI commands to see the ACL plugin state at several layers: "show acl-plugin acl [index N]" - show a high-level ACL representation, used for the linear lookup and as a base for building the hashtable-based lookup. Also shows if a given ACL is applied somewhere. "show acl-plugin interface [sw_if_index N]" - show which interfaces have which ACL(s) applied. "show acl-plugin tables" - a lower-level debug command used to see the state of all of the related data structures at once. There are specifiers possible, which make for a more focused and maybe augmented output: "show acl-plugin tables acl [index N]" show the "bitmask-ready" representations of the ACLs, we well as the mask types and their associated indices. "show acl-plutin tables mask" show the derived mask types and their indices only. "show acl-plugin tables applied [sw_if_index N]" show the table of all of the ACEs applied for a given sw_if_index or all interfaces. "show acl-plugin tables hash [verbose N]" show the 48x8 bihash used for the ACL lookup. Change-Id: I89fff051424cb44bcb189e3cee04c1b8f76efc28 Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>

2017-06-16memif: jumbo frames supportSteven2-148/+272
Current memif interface supports frame size up to 2048. This patch is to enhance memif to support jumbo frames. On tx (writing buffers to the ring), keep reading the next buffer in vlib when the flag VLIB_BUFFER_NEXT_PRESENT and merge it to the same ring entry. Use descriptor chaining if the buffer is not big enough. On rx (reading buffers from the ring), if the packet is greater than 2048, create multiple vlib buffers, chained with the VLIB_BUFFER_NEXT_PRESENT. Testing: Because the ping command provided by VPP does not support jumbo frames, I have to use linux ping. Here is the set up that I use for testing. VM1 --- vhost ---- VPP1 --- memif --- VPP2 --- vhost --- VM2 Create vhost-user interfaces between VM1 and VPP1 and between VPP2 and VM2 VM configuration: Set the interface mtu on the VM, e.g 9216 to support jumbo frames. create static route and static arp on VM1 to VM2 and vice versa. Use iperf3 or ping -s 8000 from VM1 to VM2 or vice versa. Sample run sluong@ubuntu:~$ ping 131.1.1.1 -c1 -s 8000 ping 131.1.1.1 -c1 -s 8000 PING 131.1.1.1 (131.1.1.1) 8000(8028) bytes of data. 8008 bytes from 131.1.1.1: icmp_seq=1 ttl=62 time=0.835 ms --- 131.1.1.1 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.835/0.835/0.835/0.000 ms sluong@ubuntu:~$ DBGvpp# sh interface memif0 Name Idx State Counter Count memif0 1 up rx packets 1 rx bytes 8042 tx packets 1 tx bytes 8042 ip4 1 DBGvpp# Change-Id: I469bece3d45a790dceaee1d6a8e976bd018feee2 Signed-off-by: Steven <sluong@cisco.com>

2017-06-15acl-plugin: store sessions in a single hash table instead of a per-interfaceAndrew Yourtchenko4-22/+39
A bihash-per-interface is convenient, but turns out tricky difficult from the maintenance standpoint with the large number of interfaces. This patch makes the sessions reside in a single hash table for all the interfaces, adding the lower 16 bit of sw_if_index as part of the key into the previously unused space. There is a tradeoff, that a session with an identical 5-tuple and the same sw_if_index modulo 65536 will match on either of the interfaces. The probability of that is deemed sufficiently small to not worry about it. In case it still happens before the heat death of the universe, there is a clib_warning and the colliding packet will be dropped, at which point we will need to bump the hash key size by another u64, but rather not pay the cost of doing that right now.

2017-06-14acl-plugin: shrink the L2 classifier tables used for traffic redirectAndrew Yourtchenko1-17/+17
The previous iteration of the code used the L2 classifier tables for session storage, as a result, the table allocations were pretty big. The new ACL plugin datapath uses the tables just as a redirection mechanism, without adding any entries. Thus, the tables can be much smaller.

2017-06-07VPP-873: fix vector expansion bug in dispatch_pending_nodeDave Barach1-13/+27
The main interior graph-node dispatch loop had a longstanding dangling vector element reference: for (i = 0; i < _vec_len (nm->pending_frames); i++) cpu_time_now = dispatch_pending_node (vm, nm->pending_frames + i, cpu_time_now); Passing a pointer to a vector element (nm->pending_frames + i) has considerable comedic potential if there's any chance that the vector could expand. dispatch_pending_node() calls dispatch_node(), and indirectly any interior graph node dispatch function. If that node happens to expand nm->pending_frames by filling in a new frame, nm->pending_frames can expand. After calling the node dispatch function, dispatch_node() does the following: nf = vec_elt_at_index (nm->next_frames, p->next_frame_index); If nm->pending_frames expands during dispatch function execution, p is a dangling reference to freed memory. By luck, the TCP stack managed to allocate a fresh frame which included "old-p," which caused p->next_frame_index to be filled with the new-frame poison pattern 0xfefefefe. This has been broken from day 1, summer 2007, first use of the third-generation vector processing library.
