2017-04-06acl-plugin: make the IPv4/IPv6 non-first fragment handling in line with ACL ↵Andrew Yourtchenko1-0/+7
(VPP-682) This fixes the previously-implicit "drop all non-first fragments" behavior to be more in line with security rules: a non-first fragment is treated for the purposes of matching the ACL as a packet with the port match succeeding. This allows to change the behavior to permit the fragmented packets for the default "permit specific rules" ruleset, but also gives the flexibility to block the non-initial fragments by inserting into the begining a bogus rule which would deny the L4 traffic. Also, add a knob which allows to potentially turn this behavior off in case of a dire need (and revert to dropping all non-initial fragments), via a debug CLI.

2017-03-03VPP-651: Ensure sw_if_index to node mapping for L2 output path is only done ↵Andrew Yourtchenko1-1/+5
via l2output_main.next_nodes Before this commit, several output features that happen to be the last in the list of features to be executed, send the packets directly to <interfaceName>-output. To do this, they use l2_output_dispatch, which builds a list of sw_if_index to next index mappings. When interfaces are deleted and the new interfaces are created, these mappings become stale, and cause the packets being sent to wrong interface output nodes. This patch (thanks John Lo for the brilliant idea!) adds a feature node "output", whose sole purpose is dispatching the packets to the correct interface output nodes. To do that, it uses the l2output_main.next_nodes, which is already taken care of for the case of the sw_if_index reuse, so this makes the dependent features all work correctly. Since this changes the packet path, for the features that were always the last ones it has triggered a side problem of the output feat_next_node_index not being properly initalized. These two users are l2-output-classify node and the output nodes belonging to the acl-plugin. For the first one the less invasive fix is just to initialize that field. For the acl-plugin nodes, rewrite the affected part of the code to use feat_bitmap_get_next_node_index since this is essentially what the conditional in l2_output_dispatch does, and fix the compiler warnings generated. This fix was first made in stable/1701 under commit e7dcee4027854b0ad076101471afdfff67eb9011.

2017-02-03Plugin infrastructure improvementsDamjan Marion1-23/+6
This patch replaces requirement for vlib_plugin_register function in the plugin so file and introduces new macro: VLIB_PLUGIN_REGISTER () = { .version = "version string", .version_required = "requred version", .default_disabled = 1, .early_init = "early_init_function_name", }; Plugin will nor be loaded if .default_disabled is set to 1 unless explicitely enabled in startup.conf. If .verstion_required is set, plugin will not be loaded if there is version mismatch between plugin and vpp. This can be bypassed by setting "skip-version-check" for specific plugin. If .early-init string is present, plugin loader will try to resolve this specific symbol in the plugin namespace and make a function call. Following startup.conf configuration is added: plugins { path /path/to/plugin/directory plugin ila_plugin.so { enable skip-version-check } plugin acl_plugin.so { disable } } Change-Id: I706c691dd34d94ffe9e02b59831af8859a95f061 Signed-off-by: Damjan Marion <damarion@cisco.com>
2017-01-03VPP-574: fix the MACIP ACLs blocking ARP trafficAndrew Yourtchenko1-0/+47
The initial assumption was that the MACIP ACL classifier tables would be applied after the classification of the traffic based on the ethertype, it turned out to be untrue, but the fix in the code did not happen. Add the ethertype to the mask, and the logic to create the ACL classifier tables permitting the ARP ethertype with the correct payload.
