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 Lo4-181/+456
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.
