2023-11-16dhcp: api to enable client detect on interfaceOle Troan1-0/+25
DHCPv4 aka BOOTP is somewhat awkward. A DHCP client on an interface must receive DHCP packets to the broadcast address or to a unicast address. Apparently before it's been assigned to itself. Add this new API to allow external DHCP clients enable the DHCP client detect feature per interface.

2022-05-02dhcp: fix dhcp_compl_eventJing Peng1-3/+5
This patch fixes two problems: 1. The lease field in the dhcp_compl_event message can include a list of vl_api_domain_server_t structs, but no memory is allocated for it. 2. The DNS server address is not copied properly, resulting in wrong IP4 addresses in the event message.

2020-05-27dhcp: vat support for the dhcp_client_dump APIDave Barach1-1/+1
Also: permanently solve ordering issues with the vpp builtin vat plugin loader, by explicitly loading vat plugins once we're sure that all data plane plugins have registered their APIs / API message handlers. Fix compilation / link errors when the vpp builtin vat plugin loader is disbled by cmake configuration.

2020-05-04misc: binary api fuzz test fixesDave Barach1-0/+14
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

2019-10-25dhcp: fix crash on unicast renewal sendNeale Ranns1-3/+5
Type: fix - when the addresses were learnt a copy of the client was sent to the main thread, this meant the unicast adjacecny was saved on the copy not on the original. - Add logging. - Improve the proxy-node that hands the clint packets so the DHCP packets are traced. - allow a renewal to configure new address data Change-Id: I6ab0afcccbc4a1cdefdd1b8beeda8fc7ba20ec1f Signed-off-by: Neale Ranns <nranns@cisco.com>
