2020-05-04misc: binary api fuzz test fixesDave Barach1-5/+5
Add a hook to src/vlibapi/api_shared.c to fuzz (screw up) binary API messages, e.g. by xoring random data into them before processing. We specifically exempt client connection messages, and inband debug CLI messages. We step over msg_id, client index, client context, and sw_if_index. Otherwise, "make test" vectors fail too rapidly to learn anything. The goal is to reduce the number of crashes caused to zero. We're fairly close with this patch. Add vl_msg_api_max_length(void *mp), which returns the maximum plausible length for a binary API message. Use it to hardern vl_api_from_api_to_new_vec(...) which takes an additional argument - message pointer - so it can verify that astr->length is sane. If it's not sane, return a u8 *vector of the form "insane astr->length nnnn\0". Verify array lengths in vl_api_dhcp6_send_client_message_t_handler(...) and vl_api_dhcp6_pd_send_client_message_t_handler(...). Add a fairly effective binary API fuzz hook to the unittest plugin, and modify the "make test" framework.py to pass "api-fuzz { on|off }" to enable API fuzzing: "make API_FUZZ=on TEST=xxx test-debug" or similar Type: improvement Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: I0157267652a163c01553d5267620f719cc6c3bde
2020-02-26api: improve api string safetyJakub Grajciar2-4/+4
- Remove vl_api_from_api_string to prevent use of not nul-terminated strings. - Rename vl_api_from_api_to_vec -> vl_api_from_api_to_new_vec to imply a new vector is created. NOT nul terminated. - Add vl_api_from_api_to_new_c_string. Returns nul terminated string in a new vector. - Add vl_api_c_string_to_api_string. Convert nul terminated string to vl_api_string_t - Add vl_api_vec_to_api_string. Convert NON nul terminated vector to vl_api_string_t Type: fix Signed-off-by: Jakub Grajciar <jgrajcia@cisco.com> Change-Id: Iadd59b612c0d960a34ad0dd07a9d17f56435c6ea Signed-off-by: Jakub Grajciar <jgrajcia@cisco.com>

2019-07-09vat: unload unused vat pluginsDave Barach1-17/+19
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.

2018-01-23VPPAPIGEN: vppapigen replacement in Python PLY.Ole Troan1-1/+1
This is a version of the VPP API generator in Python PLY. It supports the existing language, and has a plugin architecture for generators. Currently C and JSON are supported. Changes: - vl_api_version to option version = "major.minor.patch" - enum support - Added error checking and reporting - import support (removed the C pre-processor) - services (tying request/reply together) Version: option version = "1.0.0"; Enum: enum colours { RED, BLUE = 50, }; define foo { vl_api_colours_t colours; }; Services: service { rpc foo returns foo_reply; rpc foo_dump returns stream foo_details; rpc want_stats returns want_stats_reply events ip4_counters, ip6_counters; }; Future planned features: - unions - bool, text - array support (including length) - proto3 output plugin - Refactor C/C++ generator as a plugin - Refactor Java generator as a plugin Change-Id: Ifa289966c790e1b1a8e2938a91e69331e3a58bdf Signed-off-by: Ole Troan <ot@cisco.com>

2017-10-03Repair vlib API socket serverDave Barach2-2/+1
- Teach vpp_api_test to send/receive API messages over sockets - Add memfd-based shared memory - Add api messages to create memfd-based shared memory segments - vpp_api_test supports both socket and shared memory segment connections - vpp_api_test pivot from socket to shared memory API messaging - add socket client support to libvlibclient.so - dead client reaper sends ping messages, container-friendly - dead client reaper falls back to kill (<pid>, 0) live checking if e.g. a python app goes silent for tens of seconds - handle ping messages in python client support code - teach show api ring about pairwise shared-memory segments - fix ip probing of already resolved destinations (VPP-998) We'll need this work to implement proper host-stack client isolation Change-Id: Ic23b65f75c854d0393d9a2e9d6b122a9551be769 Signed-off-by: Dave Barach <dave@barachs.net> Signed-off-by: Dave Wallace <dwallacelf@gmail.com> Signed-off-by: Florin Coras <fcoras@cisco.com>

2017-02-02Refactor fragile msg macro W and W2 to not burry return control flow.Jon Loeliger1-6/+12
Instead, have them accept and assign a return paramter leaving the return control flow up to the caller. Clean up otherwise misleading returns present even after "NOT REACHED" comments. Change-Id: I0861921f73ab65d55b95eabd27514f0129152723 Signed-off-by: Jon Loeliger <jdl@netgate.com>
