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.

2021-10-21fib: respect mfib entry flags on create with pathsPaul Atkins1-3/+3
When an mfib entry was created with both paths and entry_flags then the entry flags were being ignored. If there are no paths then the flags were passed into mfib_table_entry_update, but in the case where the entry didn't exist and there were paths and flags, the entry was created within mfib_table_entry_paths_update() which used a default of MFIB_ENTRY_FLAG_NONE. Pass the flags through into the mfib_table_entry_paths_update fn. All existing callers other than the create case will now pass in MFIB_ENTRY_FLAG_NONE.

2021-05-01vlib: refactor trajectory trace debug featureBenoît Ganne3-3/+0
trajectory trace has been broken for a while because we used to save the buffer trajectory in a vector pointed to in opaque2. This does not work well when opaque2 is copied (eg. because of a clone) as 2 buffers end up sharing the same vector. This dedicates a full cacheline in the buffer metadata instead when trajectory is compiled in. No dynamic allocation, no sharing, no tears.

2020-08-27tests: "force solo" testcase supportAndrew Yourtchenko2-0/+8
Some of the tests are time-sensitive, and at present require a non-trivial modification in order to run at high concurrency. Without these modifications, they intermittently fail, and require the test retries. Rather than setting them to the extended tests and forgetting about them, put them into a "solo" set, which gets run in a single-threaded mode after the rest of the tests are done. Mark a few of the tests that showed errors during TEST_JOBS=48 as forced-solo. Also, give a better diagnostic if the testcase misses a docstring needed to represent it in the diagnostic outputs.

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

2019-11-10dhcp: 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
