2018-02-07classifier-based ACL: refactor + add output ACLAndrew Yourtchenko1-0/+45
For implementation of MACIP ACLs enhancement (VPP-1088), an outbound classifier-based ACL would be needed. There was an existing incomplete code for outbound ACLs, it looked almost exact copy of input ACLs, minus the various enhancements, trying to sync that code seemed error-prone and cumbersome to maintain in the longer run. This change refactors the input+output ACLs processing into a unified routine (thus any changes will have effect on both), and also adds the API to set the output interface ACL, with the same format and semantics as the existing input one (except working on output ACL of course). WARNING: IP outbound ACL in L3 mode clobbers the ip.* fields in the vnet_buffer_opaque_t, since the code is using l2_classify.* The net_buffer (p0)->ip.save_rewrite_length is rescued into l2_classify.pad.l2_len, and used to rewind the header in case of drop, so that ipX_drop prints something sensible.

2016-12-23make test: improve handling of packet capturesKlement Sekera1-39/+46
Perform accounting of expected packets based on created packet infos. Use this accounting info to automatically expect (and verify) the correct number of packets to be captured. Automatically retry the read of the capture file if scapy raises an exception while doing so to handle rare cases when capture file is read while only partially written during busy wait. Don't fail assert_nothing_captured if only junk packets arrived. Change-Id: I16ec2e9410ef510d313ec16b7e13c57d0b2a63f5 Signed-off-by: Klement Sekera <ksekera@cisco.com>
