2020-02-26api: improve api string safetyJakub Grajciar1-1/+1
- 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>

2019-09-16api: autogenerate api trace print/endianOle Troan1-2/+4
In addition to the external vppapitrace tool, VPP itself supports dumping of API trace files. In two formats, "custom-dump" and "dump". "dump" gives a human friendly list, and "custom-dump" is meant to give a list of commands that can be fed to VAT. This patch only deals with "dump". Prior to this fix, auto-generation was only done for the basic types. This fix adds support for any type, including lists, and supports pretty-printing of enums, strings, IP addresses, MAC addresses and so on. Usage: api trace dump <api-trace-file> For example Change-Id: I4e485680e6dcfce7489299ae6cf31d835071ac40 ---------- trace 48 ----------- vl_api_sw_interface_set_flags_t: _vl_msg_id: 75 client_index: 0 context: 10 sw_if_index: 1 flags: IF_STATUS_API_FLAG_ADMIN_UP ---------- trace 49 ----------- vl_api_sw_interface_add_del_address_t: _vl_msg_id: 88 client_index: 0 context: 11 sw_if_index: 1 is_add: 1 del_all: 0 prefix: 172.16.1.1/24 ---------- trace 51 ----------- vl_api_cli_inband_t: _vl_msg_id: 819 client_index: 0 context: 13 cmd: packet-generator capture pg0 pcap /tmp/vpp-unittest-TestMAP-YhcmDX/pg0_out.pcap disable ---------- trace 58 ----------- vl_api_ip_neighbor_add_del_t: _vl_msg_id: 199 client_index: 0 context: 20 is_add: 1 neighbor: sw_if_index: 2 flags: IP_API_NEIGHBOR_FLAG_NONE mac_address: 0202.0000.ff02 ip_address: fd01:2::2 Signed-off-by: Ole Troan <ot@cisco.com> Change-Id: I5556d06008de2762e7c2d35a8b0963ae670b3db1 Type: fix Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com>
2019-09-03api: enforce vla is last and fixed string typeOle Troan1-17/+13
Enforce that variable length fields are the last element of API messages. Add a 'fixed' version of string type, since dealing with multiple variable length strings turned out too painful for the C language bindings. The string type is now: { string name[64]; // NUL terminated C-string. Essentially decays to u8 name[64] string name[]; // Variable length string with embedded len field (vl_api_string_t) }; The latter notation could be made available to other types as well. e.g. { vl_api_address_t addresses[]; } instead of { u32 n_addr; vl_api_address_t addresses[n_addr]; }; Type: fix Change-Id: I18fa17ef47227633752ab50453e8d20a652a9f9b Signed-off-by: Ole Troan <ot@cisco.com>

2019-07-23api: binary api cleanupDave Barach1-0/+3
Multiple API message handlers call vnet_get_sup_hw_interface(...) without checking the inbound sw_if_index. This can cause a pool_elt_at_index ASSERT in a debug image, and major disorder in a production image. Given that a number of places are coded as follows, add an "api_visible_or_null" variant of vnet_get_sup_hw_interface, which returns NULL given an invalid sw_if_index, or a hidden sw interface: - hw = vnet_get_sup_hw_interface (vnm, sw_if_index); + hw = vnet_get_sup_hw_interface_api_visible_or_null (vnm, sw_if_index); if (hw == NULL || memif_device_class.index != hw->dev_class_index) return clib_error_return (0, "not a memif interface"); Rename two existing xxx_safe functions -> xxx_or_null to make it obvious what they return.

leak-check { <any-debug-cli-command-and-args> } Hint: "set term history off" or you'll have to sort through a bunch of bogus leaks related to the debug cli history mechanism. Cleaned up a set of reported leaks in the "show interface" command. At some point, we thought about making a per-thread vlib_mains vector, but we never did that. Several interface-related CLI's maintained local static cache vectors. Not a bad idea, but not useful as things shook out. Removed the static vectors.

2019-04-10API: Fix shared memory only action handlers.Ole Troan1-52/+69
Some API action handlers called vl_msg_ai_send_shmem() directly. That breaks Unix domain socket API transport.
