2020-05-28dhcp: use per-thread vlib main instead of global oneBenoît Ganne1-2/+2

2020-05-27dhcp: vat support for the dhcp_client_dump APIDave Barach2-4/+33
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

2020-04-13dhcp: fix unicast pkts, clean up state machineDave Barach2-49/+42
Send dhcp unicast packets to ip4-lookup. Otherwise, these packets won't reach a dhcp server on a different subnet. Do an immediate client scan after processing wakeup events. Calculate the next process wakeup time by scanning all clients. Increase maximum (idle, no-clients-configured) timeout to 1000 seconds. Reduce log spew.

2019-11-27nat: fix dhcp client on outside interface with output featureAlexander Chernavin1-0/+1
When a DHCP client is configured on a NAT outside interface with output feature enabled, DHCP packets will reach the NAT in2out-output node and will be dropped with "out of ports" reason. With this commit, allow locally originated DHCP packets to be sent from a NAT outside interface with output feature enabled.

2019-11-10dhcp: ipv6 prefix delegation improvementsDave Barach1-10/+96
Autoconfigure router advertisements for delegated prefixes. Clean up a longstanding issue. If vpp receives a dhcpv6 renew reply, do NOT reset per-delegated-prefix timers. That prevented vpp from sending a solicit to renew the delegation on time. That, in turn caused the RA code to send advertisements with valid_time = preferred_time = 0. That causes almost any downstream client to throw away its delegated address. Miscellaneous changes o src/vnet/ip/ip6_neighbor.c - always memset elements allocated from pools to zero. DGMS. o Remove debug spew from the ipv6 connection-tracker plugin Type: feature Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: I428feccdc47efdc413898600e0d62916928a6eb7
2019-11-09dhcp: fix dhcpv6 client and dhcpv6 prefix delegationDave Barach3-37/+19
Keep trying even if the interface in question is not "admin-up, link-up." In real life, it's normal for link autonegotiation to take a good fraction of a second. The driver layer takes care of packets sent to an interface which can't transmit at the moment. Renew address leases at the preferred renewal time, not at the expiration time.
