vppapigen now generates per-message crcs. Verified that whitespace and real changes in message A don't change the crc for message B, etc. Fixed the sample and flowperpkt plugins to participate. Others need the same treatment. They don't build due to python/java language binding build issues. To use the scheme: Client connects as usual. Then call: u32 vl_api_get_msg_index(char * name_and_crc) name_and_crc is a string like: "flowperpkt_tx_interface_add_del_753301f3", aka the message name with _%08x <expected crc> appended. Try these vpp-api-test commands to play with it: vat# dump_msg_api_table <snip> [366]: punt_reply_cca27fbe [367]: ipsec_spd_dump_5e9ae88e [368]: ipsec_spd_details_6f7821b0 [369]: sample_macswap_enable_disable_0f2813e2 [370]: sample_macswap_enable_disable_reply_476738e5 [371]: flowperpkt_tx_interface_add_del_753301f3 [372]: flowperpkt_tx_interface_add_del_reply_d47e6e0b vat# get_msg_id sample_macswap_enable_disable_reply_476738e5 'sample_macswap_enable_disable_reply_476738e5' has message index 370 vat# get_msg_id sample_macswap_enable_disable_reply_476738e3 'sample_macswap_enable_disable_reply_476738e3' not found CRCs may vary, etc. vppapigen is used to build a set of JSON representations of each API file from vpp-api/Makefile.am and that is in turn used by each language binding (Java, Python, Lua).

How to construct a complete plugin using the emacs skeletons 0. Install open-vpp, including the development package. 1. Load emacs skeletons M-x find-file all-skel.el M-x eval-buffer 2. Pick a single-word, lower-case name for your plugin. For example: macswap. Hereafter, we'll refer to the selected name as <plugin-name>. 3. Generate the entire plugin: M-x make-plugin Plugin-name: <plugin-name> Or, generate each file individually: 3. Create the required directories, e.g. under .../vpp $ mkdir -p <plugin-name>-plugin/<plugin-name> 4. Create <plugin-name>-plugin/{configure.ac,Makefile.am} M-x find-file <plugin-name>-plugin/configure.ac M-x plugin-configure-skel M-x find-file <plugin-name>-plugin/Makefile.am M-x skel-plugin-makefile 5. Create the api skeleton M-x find-file <plugin-name>-plugin/<plugin-name>/<plugin-name>.api M-x skel-plugin-api 6. Create the api message enumeration header file M-x find-file <plugin-name>-plugin/<plugin-name>/<plugin-name>_msg_enum.h M-x skel-plugin-msg-enum 7. Create the "all-api" header file M-x find-file <plugin-name>-plugin/<plugin-name>/<plugin-name>_all_api_h.h M-x skel-plugin-all-apih 8. Create the main data structure definition header file M-x find-file <plugin-name>-plugin/<plugin-name>/<plugin-name>.h M-x skel-plugin-h 9. Create the plugin main C file M-x find-file <plugin-name>-plugin/<plugin-name>/<plugin-name>.c M-x skel-plugin-main 10. Create the vpp-api-test plugin main C file M-x find-file <plugin-name>-plugin/<plugin-name>/<plugin-name>_test.c M-x skel-plugin-test 11. Create the data plane packet processing node M-x find-file <plugin-name>-plugin/<plugin-name>/node.c M-x skel-plugin-node 12. Process autotools input files $ cd <plugin-name>-plugin $ autoreconf -i -f 13. Build the plugin skeleton $ mkdir build $ cd build $ ../configure --with-plugin-toolkit $ make $ sudo make install
