2019-09-25api: split api generated filesOle Troan4-200/+9
Split generation of API message enum and the typedefs into separate files, so that the type file can be included from elsewhere. Generate a C file for VPP that contains the API registration, this was previously done via X macros by the C pre- processor. This allows deleting lots of skeleton/copy paste code for each feature. plugins/flowprobe plugins/map examples/sample-plugin vnet/ipip used as Guinea pigs. Generate a C Test file for VAT, that does the same for VAT plugins. Also add support for a per-message CLI option, that is currently limited to VAT help text. option vat_help = "<help text>"; Type: refactor Change-Id: I245e3104bb76f7e1fb69a59ab20cc7c8dfcdd460 Signed-off-by: Ole Troan <ot@cisco.com>
2019-09-16api: autogenerate api trace print/endianOle Troan1-1/+1
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 <api-trace-file> 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 <ot@cisco.com> Change-Id: I5556d06008de2762e7c2d35a8b0963ae670b3db1 Type: fix Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com>

2019-07-09vat: unload unused vat pluginsDave Barach1-27/+11
If the corresponding vpp plugin is absent, return a non-zero clib_error_t * from vat_plugin_register ("xxx plugin not loaded"). The vat plugin calls dlclose on the vat plugin, and it disappears. Depending on the plugin configuration, this can reduce the vpp virtual size by several gigabytes. Added a VAT_PLUGIN(<plugin-name>) macro to vat_helper_macros, clean up boilerplate vat_plugin_register() implementations. Fixed a number of non-standard vat_plugin_register methods.

2019-05-16init / exit function orderingDave Barach1-8/+7
The vlib init function subsystem now supports a mix of procedural and formally-specified ordering constraints. We should eliminate procedural knowledge wherever possible. The following schemes are *roughly* equivalent: static clib_error_t *init_runs_first (vlib_main_t *vm) { clib_error_t *error; ... do some stuff... if ((error = vlib_call_init_function (init_runs_next))) return error; ... } VLIB_INIT_FUNCTION (init_runs_first); and static clib_error_t *init_runs_first (vlib_main_t *vm) { ... do some stuff... } VLIB_INIT_FUNCTION (init_runs_first) = { .runs_before = VLIB_INITS("init_runs_next"), }; The first form will [most likely] call "init_runs_next" on the spot. The second form means that "init_runs_first" runs before "init_runs_next," possibly much earlier in the sequence. Please DO NOT construct sets of init functions where A before B actually means A *right before* B. It's not necessary - simply combine A and B - and it leads to hugely annoying debugging exercises when trying to switch from ad-hoc procedural ordering constraints to formal ordering constraints.

2017-10-24Add extern to *_main global variable declarations in header files.Dave Wallace2-2/+2
- Global variables declared in header files without the use of the 'extern' keword will result in multiple instances of the variable to be created by the compiler -- one for each different source file in which the the header file is included.
