2022-05-19api: refactor api data storageDamjan Marion1-0/+24
single struct to hold all api handler, flags, etc. Provide functions to toggle flags instead of writing directly to internal data. Type: refactor Change-Id: I4730d7290e57489de8eda34a72211527e015b721 Signed-off-by: Damjan Marion <damarion@cisco.com>
2022-03-23api: better segregate client and server codeBenoît Ganne1-4/+0
- move memory and server specific vl_msg_api_handler_with_vm_node() to memory server code only - keep api_global_main static Apart from being cleaner, this also helps avoiding symbols conflict when both client and server libs are loaded in the same process, as is done by the prom plugin. Those symbols conflict confuse ASan and can be nasty to debug. Type: improvement Change-Id: Iaf58596cc753ad8d3fedd8d65c4bf480ac129c2c Signed-off-by: Benoît Ganne <bganne@cisco.com>
2021-09-28api: API trace improvementsFilip Tehlar1-2/+7
Type: improvement * add support for JSON format in API trace * add ability to replay JSON API trace in both VPP and VAT2 * use CRC for backward compatibility check during JSON API replay * fix API trace CLI (and remove duplicits) * remove custom dump * remove vppapitrace.py * update docs accordingly Change-Id: I5294f68bebe6cbe738630f457f3a87720e06486b Signed-off-by: Filip Tehlar <ftehlar@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com>
2020-05-04misc: binary api fuzz test fixesDave Barach1-0/+1
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

2019-08-08api: vppapitrace JSON/API trace converterOle Troan1-2/+2
usage: vppapitrace.py [-h] [--debug] [--apidir APIDIR] {convert,replay} ... optional arguments: -h, --help show this help message and exit --debug enable debug mode --apidir APIDIR Location of JSON API definitions subcommands: valid subcommands {convert,replay} additional help convert Convert API trace to JSON or Python and back replay Replay messages to running VPP instance To convert an API trace file to JSON: vppapitrace convert /tmp/api.trace trace.json To convert an (edited) JSON file back to API trace for replay: vppapitrace convert trace.json api-edited.trace To generate a Python file that can be replayed: vppapitrace convert /tmp/api.trace trace.py vppapitrace convert trace.json trace.py Replay it to a running VPP instance: vppapitrace replay --socket /tmp/api.trace In VPP that file can be replayed with: vpp# api trace replay api-edited.trace This patch also modifies the API binary trace format, to include the message id to message name table.

2018-06-13Stat segment / client: show run" works nowDave Barach1-1/+1
Seems to have minimal-to-zero performance consequences. Data appears accurate: result match the debug CLI output. Checked at low rates, 27 MPPS sprayed across two worker threads. Change-Id: I09ede5150b88a91547feeee448a2854997613004 Signed-off-by: Dave Barach <dave@barachs.net>
2018-01-09api: refactor vlibmemoryFlorin Coras1-9/+7
- separate client/server code for both memory and socket apis - separate memory api code from generic vlib api code - move unix_shared_memory_fifo to svm and rename to svm_fifo_t - overall declutter Change-Id: I90cdd98ff74d0787d58825b914b0f1eafcfa4dc2 Signed-off-by: Florin Coras <fcoras@cisco.com>

2017-03-02Clean up binary api message handler registration issuesDave Barach1-0/+15
Removed a fair number of "BUG" message handlers, due to conflicts with actual message handlers in api_format.c. Vpp itself had no business receiving certain messages, up to the point where we started building in relevant code from vpp_api_test. Eliminated all but one duplicate registration complaint. That one needs attention from the vxlan team since the duplicated handlers have diverged. Change-Id: Iafce5429d2f906270643b4ea5f0130e20beb4d1d Signed-off-by: Dave Barach <dave@barachs.net>
