2020-12-03stats: char-pointer arithmetic style-upVratko Polak1-6/+4
Char* typed shared_header value appears multiple times, so store it is a variable. Pointer "p" value is used more frequently casted to char*, so use that type for it, and convert to void* only at return.

2020-11-25api: vat2 and json autogeneration for api messagesOle Troan2-4/+4
VAT2: A completely auto-generated replacement of VAT. Reads input message in JSON from stdin and outputs received messages in JSON. A VAT2 plugin is automatically built for a .api file. There no longer a need for a separate _test.c. Example: vat2 show_version {} { "_msgname": "show_version_reply", "retval": 0, "program": "vpe", "version": "21.01-rc0~411-gf6eb348a6", "build_date": "2020-11-19T09:49:25", "build_directory": "/vpp/autogen3" } vat2 sw_interface_dump '{"sw_if_index": -1, "name_filter_valid": 0, "name_filter": ""}' [{ "_msgname": "sw_interface_details", "sw_if_index": 0, "sup_sw_if_index": 0, "l2_address": "00:00:00:00:00:00", "flags": "Invalid ENUM", "type": "IF_API_TYPE_HARDWARE", "link_duplex": "LINK_DUPLEX_API_UNKNOWN", "link_speed": 0, "link_mtu": 0, "mtu": [0, 0, 0, 0], "sub_id": 0, "sub_number_of_tags": 0, "sub_outer_vlan_id": 0, "sub_inner_vlan_id": 0, "sub_if_flags": "Invalid ENUM", "vtr_op": 0, "vtr_push_dot1q": 0, "vtr_tag1": 0, "vtr_tag2": 0, "outer_tag": 0, "b_dmac": "00:00:00:00:00:00", "b_smac": "00:00:00:00:00:00", "b_vlanid": 0, "i_sid": 0, "interface_name": "local0", "interface_dev_type": "local", "tag": "" }] This is the first phase and vat2 is not integrated in packaging yet.

2020-10-21stats: missing dimension in stat_set_simple_counterOle Troan2-8/+24
A simple counter is a two dimensional array by threads and counter index. 28017 introduced an error missing the first dimension. If a vector is updated at the same time as a client reads, an invalid pointer my result. This will be caught by the optimistic locking after copying out the data, but if following a pointer outside of the stat segment then the stat client would crash. Add suitable boundary checks for access to stat memory segment.

2020-02-05stats: fix state counter removalVladimir Isaev1-0/+3
Avoid using vec_del1() for directory vector to keep indexes valid all the time. There are state counters for each slave in LACP bond mode which can be dynamically created and removed. Vector index is used to access these counters. But also vec_del1() is used to remove counter from vector. This function changes the index of the last element, so after this we are unable to access ex-last element using old index. As a result it is not possible to add-del-add two interfaces to the LACP bond: DBGvpp# create bond mode lacp BondEthernet0 DBGvpp# create packet-generator interface pg1 DBGvpp# create packet-generator interface pg2 DBGvpp# bond add BondEthernet0 pg1 DBGvpp# bond add BondEthernet0 pg2 DBGvpp# bond del pg1 DBGvpp# bond del pg2 DBGvpp# bond add BondEthernet0 pg1 DBGvpp# bond add BondEthernet0 pg2 bond add: /if/lacp/1/3/partner-state is already register Type: fix Signed-off-by: Vladimir Isaev <visaev@netgate.com> Change-Id: I2c86e13905eefdef6233369cd4ab5c1b53d123bd
