From 8d61c59c3f1e05e49b89a700a1640aa9bcebc6b8 Mon Sep 17 00:00:00 2001 From: Pim van Pelt Date: Sat, 10 Jun 2023 16:46:34 +0200 Subject: mpls: add mpls_interface_dump Add an API call mpls_interface_dump() which returns a list of mpls_interface_details: - If no sw_if_index is given, all MPLS enabled sw_if_index are returned. - If a particular sw_if_index is given, and it doesn't exist, an empty list is returned. - If a sw_if_index exists and has MPLS enabled, a list of that one sw_if_index is returned. Tested: - Create 3 loopback interfaces - Call for ~0 and for sw_if_index 0..5 all return empty lists - set int mpls loop0 enable - set int mpls loop1 enable - Call for ~0 returns 2, and the call for sw_if_index=1 and =2 (the loopbacks) returns each a list of one sw_if_index 1 resp 2, the other values of sw_if_index return empty list - set int mpls loop0 disable - Call for ~0 returns 1, and the call for sw_if_index=2 (loop1) returns both a list of one sw_if_index=2, the other values of sw_if_index return empty list - set int mpls loop1 disable - Call for ~0 and for sw_if_index 0..5 all return empty lists Example Python3 API program: ``` api_response = vpp.api.mpls_interface_dump() print(f"Response is {api_response}") for i in [ 0, 1, 2, 3, 4, 5 ]: api_response = vpp.api.mpls_interface_dump(sw_if_index=i) print(f"Response[{i}] = {api_response}") ``` Type: improvement Change-Id: If87f7d7f8972d99260e859757dbcb251c6fa54a8 Signed-off-by: Pim van Pelt --- src/vnet/mpls/mpls_api.c | 48 ++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 48 insertions(+) (limited to 'src/vnet/mpls/mpls_api.c') diff --git a/src/vnet/mpls/mpls_api.c b/src/vnet/mpls/mpls_api.c index fac52827e1d..dcda0a66310 100644 --- a/src/vnet/mpls/mpls_api.c +++ b/src/vnet/mpls/mpls_api.c @@ -409,6 +409,54 @@ vl_api_mpls_table_dump_t_handler (vl_api_mpls_table_dump_t * mp) /* *INDENT-ON* */ } +static void +send_mpls_interface_details (vpe_api_main_t *am, vl_api_registration_t *reg, + u32 context, const u32 sw_if_index) +{ + vl_api_mpls_interface_details_t *mp; + + mp = vl_msg_api_alloc_zero (sizeof (*mp)); + mp->_vl_msg_id = ntohs (REPLY_MSG_ID_BASE + VL_API_MPLS_INTERFACE_DETAILS); + mp->context = context; + + mp->sw_if_index = htonl (sw_if_index); + vl_api_send_msg (reg, (u8 *) mp); +} + +static void +vl_api_mpls_interface_dump_t_handler (vl_api_mpls_interface_dump_t *mp) +{ + vpe_api_main_t *am = &vpe_api_main; + vl_api_registration_t *reg; + vnet_interface_main_t *im = &vnet_main.interface_main; + vnet_sw_interface_t *si; + u32 sw_if_index = ~0; + + reg = vl_api_client_index_to_registration (mp->client_index); + if (!reg) + return; + sw_if_index = ntohl (mp->sw_if_index); + + if (sw_if_index == ~0) + { + pool_foreach (si, im->sw_interfaces) + { + if (mpls_sw_interface_is_enabled (si->sw_if_index)) + { + send_mpls_interface_details (am, reg, mp->context, + si->sw_if_index); + } + } + } + else + { + if (mpls_sw_interface_is_enabled (sw_if_index)) + { + send_mpls_interface_details (am, reg, mp->context, sw_if_index); + } + } +} + static void send_mpls_route_details (vpe_api_main_t * am, vl_api_registration_t * reg, -- cgit 1.2.3-korg
