2017-06-21acl-plugin: CLI to clear all sessionsAndrew Yourtchenko2-8/+38
It is useful to have the CLI to clear the existing sessions. There was a work-in-progress CLI but it did not work properly. Fix it and split into a separate "clear acl-plugin sessions", and add a unit test into the extended connection-oriented tests.

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.

2017-05-29memif: master instance crashes when typing quit on slaveSteven1-15/+29

Create 3 memif interfaces between slave and master instances. 2. Type 'quit' on the slave. Neither crashes the first time. 3. Bring back the slave. Type 'quit' on the master. Neither crashes. 4. Bring back the master. Type 'quit' on the slave. The master crashes. There are two places the interrupt line is disconnected and the unix file is removed via the call unix_file_del () 1. memif_int_fd_read_ready () 2. memif_disconnect () which is called via multiple places in memif. When the crash happens, the unix file was removed from memif_disconnect () via memif_conn_fd_read_ready () with size of the message == 0 in recvmsg (). It is noted when the unix file was removed from memif_int_fd_read_ready (), it never crashes. It is a race condition. However, if I follow the aformentioned procedure, the crash always happens. The reason the crash happens when memif_disconnect () removes the unix file is because there may still be pending input in linux_epoll_input (). When linux_epoll_input () tries to access the unix file via the line 200 unix_file_t *f = pool_elt_at_index (um->file_pool, i); it crashes. We could add code in linux_epoll_input () to avoid the crash if the index for the particular file_pool is already free. Or we could fix memif to not remove the unix file in memif_conn_fd_read_ready () when recvmsg () got 0 byte and just postpone the unix file deletion in memif_int_fd_read_ready () later after linux_epoll_input () got a chance to run to empty the input stream. I choose to fix the problem in the latter approach. I split the function memif_disconnect () into two parts. For the code path which memif_conn_fd_read_ready () calls memif_disconnect (), it does not remove the unix file. All other calls to memif_disconnect () will continue to do what it uses to do to avoid regression. Please let me know if I should fix the problem other way.

2017-05-18acl-plugin: reject the too-short variable-length messages from clients (VPP-839)Andrew Yourtchenko1-3/+42
Prior to commit bfd9227e6da567e0e19e026afe94cd4c0b65f725, there was no clean way to check the lower-level message length as supplied by the client, so there was no option but to trust that the client does the right thing and allocates memory correctly. The absence of checks makes it hard for a misbehaving client to spot the problem - because everything "appears" to work correctly for the specific erroneous message exchange. This commit ensures the message received is at least as big as we expect, and complains loudly if it is not.
