2018-01-06Unify/cleanup usage of hash_set/unset_mem by tunnels (VPP-1117)John Lo1-23/+7
Move the functions hash_set_key_copy() and hash_unset_key_free() which are dupilicated in various tunnel support code modules to hash.h as hash_set_mem_alloc() and hash_unset_mem_free() to be used by all.

2017-03-07CLI: hide deleted interfacesEyal Bari1-0/+7
Added a new interface flag - HIDDEN Indicates that the interface does not appear in CLI/API. Added three new interface functions: vnet_sw_interface_is_api_visible - indicates if the sw_if_index should be displayed vnet_swif_is_api_visible - variant for sw_interface vnet_sw_interface_is_api_valid - tests if the given if_index exists and is visible for future use by api functions Changed the unformat function to only accept visible interfaces Changed vxlan to add the HIDDEN flag to deleted interfaces This is the first part in a series to hide deleted interfaces from the API Change-Id: Ib43cc5cf1c450856560faf4e84126eb3671038e2 Signed-off-by: Eyal Bari <ebari@cisco.com>

2017-02-22VPP-635: CLI Memory leak with invalid parameterBilly McFall1-19/+62
In the CLI parsing, below is a common pattern: /* Get a line of input. */ if (!unformat_user (input, unformat_line_input, line_input)) return 0; while (unformat_check_input (line_input) != UNFORMAT_END_OF_INPUT) { if (unformat (line_input, "x")) x = 1; : else return clib_error_return (0, "unknown input `%U'", format_unformat_error, line_input); } unformat_free (line_input); The 'else' returns if an unknown string is encountered. There a memory leak because the 'unformat_free(line_input)' is not called. There is a large number of instances of this pattern. Replaced the previous pattern with: /* Get a line of input. */ if (!unformat_user (input, unformat_line_input, line_input)) return 0; while (unformat_check_input (line_input) != UNFORMAT_END_OF_INPUT) { if (unformat (line_input, "x")) x = 1; : else { error = clib_error_return (0, "unknown input `%U'", format_unformat_error, line_input); goto done: } } /* ...Remaining code... */ done: unformat_free (line_input); return error; } In multiple files, 'unformat_free (line_input);' was never called, so there was a memory leak whether an invalid string was entered or not. Also, there were multiple instance where: error = clib_error_return (0, "unknown input `%U'", format_unformat_error, line_input); used 'input' as the last parameter instead of 'line_input'. The result is that output did not contain the substring in error, instead just an empty string. Fixed all of those as well. There are a lot of file, and very mind numbing work, so tried to keep it to a pattern to avoid mistakes.

2017-01-31Add vxlan-bypass feature to IP6 forwarding pathJohn Lo1-0/+171
Add vxlan-bypass feature which can be enabled on the IP6 underlay interface which receive VXLAN packets to accelerate VXLAN decap processing. The CLI to enable/disable it is: set interface ip6 vxlan-bypass <interface> [del] The vxlan-bypass feature is already supported on the IP4 underlay interface. The CLI to enable/disable it is: set interface ip vxlan-bypass <interface> [del] Move vxlan-bypass API/CLI support code from decap.c to vxlan.c. Also fixed two issues in the VXLAN decap path in the vxlan-input node: 1. Add verification of VXLAN packet FIB index with the encap-vrf-id of the VXLAN tunnel. 2. Fix checking of VXLANoIPv6 packet mcast DIP against that of the IP6 mcast VXLAN tunnel. Change-Id: I2bad4074a468c48fbb8bb5ac64f6437190756ed2 Signed-off-by: John Lo <loj@cisco.com>
2017-01-27IP Multicast FIB (mfib)Neale Ranns1-30/+82
- IPv[46] mfib tables with support for (*,G/m), (*,G) and (S,G) exact and longest prefix match - Replication represented via a new replicate DPO. - RPF configuration and data-plane checking - data-plane signals sent to listening control planes. The functions of multicast forwarding entries differ from their unicast conterparts, so we introduce a new mfib_table_t and mfib_entry_t objects. However, we re-use the fib_path_list to resolve and build the entry's output list. the fib_path_list provides the service to construct a replicate DPO for multicast. 'make tests' is added to with two new suites; TEST=mfib, this is invocation of the CLI command 'test mfib' which deals with many path add/remove, flag set/unset scenarios, TEST=ip-mcast, data-plane forwarding tests. Updated applications to use the new MIFB functions; - IPv6 NS/RA. - DHCPv6 unit tests for these are undated accordingly.
