From 33a58171e5995d9e649b414bfc77f2aab26e4c58 Mon Sep 17 00:00:00 2001 From: Ole Troan Date: Wed, 4 Sep 2019 09:12:29 +0200 Subject: api: autogenerate api trace print/endian In addition to the external vppapitrace tool, VPP itself supports dumping of API trace files. In two formats, "custom-dump" and "dump". "dump" gives a human friendly list, and "custom-dump" is meant to give a list of commands that can be fed to VAT. This patch only deals with "dump". Prior to this fix, auto-generation was only done for the basic types. This fix adds support for any type, including lists, and supports pretty-printing of enums, strings, IP addresses, MAC addresses and so on. Usage: api trace dump For example Change-Id: I4e485680e6dcfce7489299ae6cf31d835071ac40 ---------- trace 48 ----------- vl_api_sw_interface_set_flags_t: _vl_msg_id: 75 client_index: 0 context: 10 sw_if_index: 1 flags: IF_STATUS_API_FLAG_ADMIN_UP ---------- trace 49 ----------- vl_api_sw_interface_add_del_address_t: _vl_msg_id: 88 client_index: 0 context: 11 sw_if_index: 1 is_add: 1 del_all: 0 prefix: 172.16.1.1/24 ---------- trace 51 ----------- vl_api_cli_inband_t: _vl_msg_id: 819 client_index: 0 context: 13 cmd: packet-generator capture pg0 pcap /tmp/vpp-unittest-TestMAP-YhcmDX/pg0_out.pcap disable ---------- trace 58 ----------- vl_api_ip_neighbor_add_del_t: _vl_msg_id: 199 client_index: 0 context: 20 is_add: 1 neighbor: sw_if_index: 2 flags: IP_API_NEIGHBOR_FLAG_NONE mac_address: 0202.0000.ff02 ip_address: fd01:2::2 Signed-off-by: Ole Troan Change-Id: I5556d06008de2762e7c2d35a8b0963ae670b3db1 Type: fix Signed-off-by: Ole Troan Signed-off-by: Ole Troan Signed-off-by: Ole Troan Signed-off-by: Ole Troan Signed-off-by: Ole Troan Signed-off-by: Ole Troan Signed-off-by: Ole Troan Signed-off-by: Ole Troan --- src/vnet/interface_api.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'src/vnet/interface_api.c') diff --git a/src/vnet/interface_api.c b/src/vnet/interface_api.c index 3448c6037b7..687f599b616 100644 --- a/src/vnet/interface_api.c +++ b/src/vnet/interface_api.c @@ -166,8 +166,10 @@ vl_api_sw_interface_set_mtu_t_handler (vl_api_sw_interface_set_mtu_t * mp) VALIDATE_SW_IF_INDEX (mp); for (i = 0; i < VNET_N_MTU; i++) - per_protocol_mtu[i] = ntohl (mp->mtu[i]); - + { + per_protocol_mtu[i] = ntohl (mp->mtu[i]); + clib_warning ("MTU %u", per_protocol_mtu[i]); + } vnet_sw_interface_set_protocol_mtu (vnm, sw_if_index, per_protocol_mtu); BAD_SW_IF_INDEX_LABEL; -- cgit 1.2.3-korg
