2021-04-16tests: cpus awarenessKlement Sekera1-60/+75
Introduce MAX_CPUS parameters to control maximum number of CPUs used by VPP(s) during testing, with default value 'auto' corresponding to all CPUs available. Calculate test CPU requirements by taking into account the number of workers, so a test requires 1 (main thread) + # of worker CPUs. When running tests, keep track of both running test jobs (controlled by TEST_JOBS parameter) and free CPUs. This then causes two limits in the system - to not exceed number of jobs in parallel but also to not exceed number of CPUs available. Skip tests which require more CPUs than are available in system (or more than MAX_CPUS) and print a warning message.

2021-03-25stats: python vpp_stats rewrite to access stat segment directlyOle Troan1-1/+1
This module implement Python access to the VPP statistics segment. It accesses the data structures directly in shared memory. VPP uses optimistic locking, so data structures may change underneath us while we are reading. Data is copied out and it's important to spend as little time as possible "holding the lock". Counters are stored in VPP as a two dimensional array. Index by thread and index (typically sw_if_index). Simple counters count only packets, Combined counters count packets and octets. Counters can be accessed in either dimension. stat['/if/rx'] - returns 2D lists stat['/if/rx'][0] - returns counters for all interfaces for thread 0 stat['/if/rx'][0][1] - returns counter for interface 1 on thread 0 stat['/if/rx'][0][1]['packets'] - returns the packet counter for interface 1 on thread 0 stat['/if/rx'][:, 1] - returns the counters for interface 1 on all threads stat['/if/rx'][:, 1].packets() - returns the packet counters for interface 1 on all threads stat['/if/rx'][:, 1].sum_packets() - returns the sum of packet counters for interface 1 on all threads stat['/if/rx-miss'][:, 1].sum() - returns the sum of packet counters for interface 1 on all threads for simple counters Type: refactor Signed-off-by: Ole Troan <ot@cisco.com> Change-Id: I1fe7f7c7d11378d06be8276db5e1900ecdb8f515 Signed-off-by: Ole Troan <ot@cisco.com>

2021-02-08tests: allow for externally supplied VPP workers config for testsAndrew Yourtchenko1-1/+17
Allow to supply the external VPP worker config for tests which do not specify the workers config explicitly, and use the tags infra to flag those that need attention in this configuration. This commit shows one example use of such a tag, there will be a separate commit with the rest of the places needing it, since that change is rather mechanical. Thus, the assumption is that the test should by default be agnostic of the VPP configuration, unless it explicitly specifies so.

2020-08-27tests: "force solo" testcase supportAndrew Yourtchenko1-1/+16
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/+5
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

2019-10-21tests: add PID of VPP under test to API dump filename for the testAndrew Yourtchenko1-1/+2
Some testclasses (e.g. IPSec) have methods with the same names, this causes a race when running in parallel to save the API and move it into the test's directory - the name of the file has only the test method name as a discriminator. Saving two traces from two VPP instances "succeeds", in that it silently overwrites the file. But only one mv operation works - the other gives an error "file not found" and fails the test. Solution: add the PID of VPP under test to the API dump filename, this way the filenames become guaranteed unique and the race is avoided.

2019-10-14tests: make pg_start() wait until pg completesAndrew Yourtchenko1-19/+13
A sizable number of tests call pg_start() to get the packets flowing and then immediately expect to have the entirety of the packets gone through. This works on powerful and unstressed hardware, but fails in beautifully random ways under load.
