2022-12-20vapi: use the correct my_context_id when disconnecting API clientsMauro Sardara1-5/+75
While before the my_client_index variable was stored as global variable in api_main_t, after commit 2ca88ff97884ec9ed20a853b13cee6d86f9c9d0f the my_client_index becomes part of vapi_ctx_t. Each API client (internal/external) connected to VPP stores its client index in vapi_ctx_t. The issue is in the client disconnection. The vapi_disconnect is untouched in patch 2ca88ff97884ec9ed20a853b13cee6d86f9c9d0f, so it keeps the behavior of using the my_client_index stored in api_main_t.

2022-12-09http_static: clean up http redirect generationDave Barach1-1/+56
Don't redirect to "favicon.ico/index.html" if you can't find "favicon.ico". If asked to serve up a nonexistent path, see if the path ends with a known suffix: ".jpg, .html, .ico" etc. If it does, flunk the request on the spot: "Error 404 Not Found." Do not issue a redirect. This change will not break the obvious corner case: if the browser asks for "its_a_dir.mp3/index.html" - and the file exists - the server will produce it.

2022-11-29stats: fix the memory leak in stat_client.cAndrew Yourtchenko1-0/+2
The issue can be reproduced by running "vpp_get_stats tightpoll" The root cause is that the control flow discards the "result" struct being prepared, along with pointer its allocated name. This results in a memory leak. Type: fix Change-Id: Ibf884e92314f19b983a0159fc1257b3fa0110443 Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>
2022-11-29rdma: fix for-loop initialization in scalar pathJieqiang Wang1-20/+35
When n_rx_packets is less then 16(VEC256) or 8(VEC128), code execution will fall into scalar path of processing packets. But with a wrong initialization value for n_left set to zero, i in the for-loop will equal to n_rx_packets. This leads to the bypass of required ip4 checksum validation and byte count endianness conversion in scalar path. Besides, refactor the code using while instead of for-loop to keep consistency with VPP code style.

2022-11-28vapi: write enumflag types to vapi headersMatthew Smith2-0/+15
Type: fix Fixes: a51f9b3747 Some IPsec message type definitions were not being written to ipsec.api.vapi.h. These include ipsec_sad_entry_add_del_v3 and ipsec_sad_entry_add. The cause appears to be that tunnel_flags, which is defined in tunnel_types.api is a special case of enum called an enumflag. These do not appear to have been handled in the code that generates the vapi header files. This patch adds processing of enumflag objects for vapi.

2022-11-28ipsec: remove redundant policy array in fast path spdPiotr Bronowski3-90/+178
Fast path spd was explicitely storing array of policy id vectors. This information was redundand, as this inofrmation is already stored in bihash table. This additional array was affecting performance when adding and removing fast path policies. The other place that needed refactoring after removing this array was cli command showing fast path policies.

2022-11-28udp: preallocate ports sparse vec mapFlorin Coras1-2/+80
Not ideal. The sparse vector used to map ports to next nodes assumes only a few ports are ever used. When udp transport is enabled this does not hold and, to make matters worse, ports are consumed in a random order. This can lead to a lot of slow updates to internal data structures which in turn can slow udp connection allocations until all ports are eventually consumed. Consequently, reallocate sparse vector, preallocate all ports and have them point to UDP_NO_NODE_SET. We could consider switching the sparse vector to a preallocated vector but that would increase memory consumption for vpp deployments that do not rely on host stack. For reference, populating one of the v4 or v6 sparse vectors in reverse order takes about 9.8s on a skylake cpu.

Type: fix     Fib entries for attached routes when sourced from FIB_SOURCE_API or FIB_SOURCE_CLI get the FIB_ENTRY_FLAG_ATTACHED flag raised on the source. Such a route added from linux-cp doesn't get this flag.     Fix this flag for linux-cp sources by passing it to the fib entry's update/create function in lcp_router_route_add().
