2017-08-21PPPoE usses a midchain adjacency stack on an interface-tx DPONeale Ranns1-1/+2
1) introduce an interface-tx DPO. This is a simple wrapper around a sw_if_index. enhance DPO stacking functions to allow per-instance next-nodes and hence allow children to stack onto the interface per-instance tx node and not on 'interface-output'. 2) update PPPoE code to use ta midchain stack on a interface-tx DPO of the encap-interface. This remove the need for pppoe_encap node (which is replaced by the adj-midchain-tx) and interface-output node is no longer used (see above). Since PPPoE encap node is no longer needed, the PPPoE seesion does not need to be retrieved in the data-path, hence the cahce misses are removed.

2017-08-17make test: collect symlinks to failed testsKlement Sekera3-2/+48
Compress files in temporary directories of failed tests and symlink the directories under /tmp/vpp-failed-unittests location - preparation for jenkins archivation. Automatically cleanup the directory at start of test run. The compression is performed only when environment variable COMPRESS_FAILED_TEST_LOGS is set to one of "yes", "y", "1". This is set in verify target, but left unset by default, so when invoking make test by hand, files won't be compressed.

2017-08-15Support proxy ARP on mirrored TAP interfacesNeale Ranns2-0/+70
When VPP has an interface whose address is also applied to a TAP interface on the host, then VPP's TAP interface will be unnumbered to the 'real' interface and do proxy ARP from the host. the curious aspect of this setup is that ARP requests from the host will come from the VPP's own address.

2017-08-10make test: detect hung testsKlement Sekera6-29/+148
Run tests in a forked process with a set of pipes to communicate keep-alives and overall result. This allows us to detect when e.g. vpp dies mid-API call causing the test to hang waiting for response (which will never come since vpp died). Support setting a (per test case) TIMEOUT make test option to set timeout, with a default timeout of 120 seconds. Example - fail the test suite if any test-case fails to finish within 300s: make TIMEOUT=300 test Change-Id: I0d04f26a7232968f4bf043adf5d5b508f5018717 Signed-off-by: Klement Sekera <ksekera@cisco.com>
2017-08-10acl-plugin: all TCP sessions treated as transient (VPP-932)Andrew Yourtchenko1-10/+140
The packet that was creating the session was not tracked, consequently the TCP flags seen within the session record never got the value for the session to get treated as being in the established state. Test-escape, so add the TCP tests which test the three phases of the TCP session life and make them all pass.

2017-08-03DHCP Client: receive unicast ACKsNeale Ranns1-21/+71
despite VPP DHCP client setting neither ciaddr nor giaddr and setting the broadcast bit (see RFC 2131 section 4.1) some DHCP servers will still send a unicast DCHPACK. So as not to drop this VPP must have both 1) a receive FIB entry for the OFFERED IP adress and 2) a 'don't drop me because of uRPF' FIB entry for the DHCP server's address.

2017-06-19acl-plugin: bihash-based ACL lookupAndrew Yourtchenko3-0/+18
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>
