2021-10-19bfd: fix bfd_key_id updateAlexander Skorichenko1-4/+8
Type: fix Currently, auth activation CLI command "bfd upd session auth activate ... conf-key-id <cki> bfd-key-id <bki>" allows to change both key-ids to new values at once. But if only bfd-key-id should be corrected, e.g. as a result of mistyping, we can't do that in a single operation, and have to deactivate auth first and then reactivate it with a correctly entered pair of ids. Currently, backend's bfd_auth_activate() function returns immediately, with no action, if it finds that submitted conf-key-id matches the current record. No check on bfd-key-id value is made. With this fix, bfd_auth_activate() checks if session's bfd-key-id has to be changed to a new value, and if so, it updates and logs appropriately.

2021-10-19bfd: fix desired_min_tx_nsec updateAlexander Skorichenko1-0/+2
Type: fix Currently, the change in desired_min_tx value initiated locally doesn't result in actual update of the transmission interval. bfd_session_t structure has two fields for each of protocol's local time parameters desired_min_tx, required_min_rx In a case of a parameter update, "config_" prefixed fields store new values sent to remote bs.config_desired_min_tx_nsec, bs.config_required_min_rx_nsec Those prefixed "effective_", keep old values, still in charge, until new ones are being negotiated between peers: bs.effective_desired_min_tx_nsec, bs.effective_required_min_rx_nsec Currently, upon termination of the Poll Sequence (negotiation) only bfd_set_effective_required_min_rx() is called to update effective RX value. TX value remains unchanged. With this fix, add a call to bfd_set_effective_desired_min_tx() to set new, acknowledged TX value in effect.

2021-05-01vlib: refactor trajectory trace debug featureBenoît Ganne1-2/+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.

If the multi-worker default VPP configuration is triggered by setting VPP_WORKER_CONFIG="workers 2", some of the tests fail for various reasons. It's a substantial number, so this change marks all of the testsets that have this issue, such that they can be addressed later independently.

2021-01-22tests: add generalized tags for tests, use them for run-solo testsAndrew Yourtchenko1-24/+7
We have accumulated several scenarios in prod or wishlists where it would be useful to have a general infra to say yes/no about a certain test, and potentially make decisions based on that, for example: - runs solo (aka 'time-dependent') - (wishlist) part of quick smoke-test set - (wishlist) intermittent failure unrelated to timing - (wishlist) test broken with a multi-worker config in vpp Refactor the current "run-solo" code to allow for this extension.

2019-07-23api: binary api cleanupDave Barach2-5/+5
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.

-fno-common makes sure we do not have multiple declarations of the same global symbol across compilation units. It helps debug nasty linkage bugs by guaranteeing that all reference to a global symbol use the same underlying object. It also helps avoiding benign mistakes such as declaring enum as global objects instead of types in headers (hence the minor fixes scattered across the source).

Remove the expensive RPC call for every received packet and replace it with lock-protected direct calls. Reinstate RPC for the less frequent notification traffic. Adjust the wakeup event sending logic to minimize the number of events sent, by measuring the time it takes from sending the event to processing it, and subsequently not sending the event if the pending wake-up time is within 2x or the event propagation delay. Eventually: remove oingo / oingoes.
