2017-03-06make test: don't run if other vpp process runsKlement Sekera1-2/+22
Check if there are existing vpp processes before running the test suite and refuse to run if there are. This prevents the removal of other test suite temporary files and also makes sure that if the machine is loaded by (zombie) vpp processes, interactive tests (like bfd) won't fail.

2017-03-04timing wheel: avoid queueing expired timers and caching wrong earliest ↵Andrew Yourtchenko1-2/+11
expiry value This commit addresses two issues: 1) Avoid refilling the timing wheel with stale timers in rare circumstances. The timing_wheel_advance() may call advance_cpu_time_base() to update the cpu_time_base, which is used as a starting point for 32-bit offsets of events on the timer wheel. If the timing_wheel_advance() is not called for a longer period of time, then advance_cpu_time_base() is called multiple times in a loop. advance_cpu_time_base() has two parts - the first part adjusting the base for the existing event, and the second part trying to fill with the new events from the overflow queue, which now fit into the 32-bit-sized time window off the new cpu_time_base. In doing so this second part incorrectly considers the timers which have just expired (have the time index == w->current_time_index) to still be unexpired and places them onto the wheel instead of returning them as expired. For quick successive executions of timing_wheel_advance() these events result in a relatively benign late expiry - the newly placed events expire during the next call to timing_wheel_advance(). If the successive executions of timing_wheel_advance() result in multiple invocations of advance_cpu_time_base(), the Nth iteration of it may place a stale event on the timer wheel if the event time index equals to the current time index (which has been previously purged), while the N+1th iteration of it will trigger an assert violation on this stale event, resulting in a reboot. As part of the testing, two test runs were done before and after the change. Each of the test runs consisted of the following command: for i in `seq 1 300`; do ./test_timing_wheel validate events 10000 synthetic-time verbose seed $i iter 10000 wait-time 2 max-time 300; done The test runs completed identically, however they uncovered the following assert failure: vpp/src/vppinfra/test_timing_wheel.c:225 (test_timing_wheel_main) assertion `min_next_time[0] <= tm->events[i]' fails This assert is the second issue covered by this commit: 2) Inserting a new element may result in incorrect cached expiry value The w->cached_min_cpu_time_on_wheel is being updated within timing_wheel_advance() every time the elements are expired. However, it is not touched if the new elements are inserted. Assuming current time is "T" and the cached min cpu time is "T+X", if a new element is being inserted whose expiry time is "T+Y", and Y is such that Y < X, then the value w->cached_min_cpu_time_on_wheel becomes incorrect until the next expiry event, during which it is updated. The test catches this transient condition which results in the asserts seen in the runs above. The solution is to update the w->cached_min_cpu_time_on_wheel within timing_wheel_insert_helper() as necessary.

2017-03-03Implement a loopback instance allocation scheme.Jon Loeliger7-19/+241
To support creating loopback interfaces with a specific instance number, a new CREATE_LOOPBACK_INSTANCE API call with flag is_specified and value user_instance is introduced. Presumably the existing CREATE_LOOPBACK API message will be obsoleted and revmoved. The VAT cli commands can now mention and format the new field as 'instance %d' data. If no instance number is named, the old call CREATE_LOOPBACK is used to maintain backward compatibility. However, if the instance is named, the new CREATE_LOOPBACK_INSTANCE message will be used. Both the dynamically allocated and user-requested instance number are tracked in a bitvector. If is_specified is 0, the next free instance will be used.. A request for a specific instance number will be granted if it is available. On error, the value ~0 is returned.

2017-03-03VPP-651: Ensure sw_if_index to node mapping for L2 output path is only done ↵Andrew Yourtchenko10-88/+53
via l2output_main.next_nodes Before this commit, several output features that happen to be the last in the list of features to be executed, send the packets directly to <interfaceName>-output. To do this, they use l2_output_dispatch, which builds a list of sw_if_index to next index mappings. When interfaces are deleted and the new interfaces are created, these mappings become stale, and cause the packets being sent to wrong interface output nodes. This patch (thanks John Lo for the brilliant idea!) adds a feature node "output", whose sole purpose is dispatching the packets to the correct interface output nodes. To do that, it uses the l2output_main.next_nodes, which is already taken care of for the case of the sw_if_index reuse, so this makes the dependent features all work correctly. Since this changes the packet path, for the features that were always the last ones it has triggered a side problem of the output feat_next_node_index not being properly initalized. These two users are l2-output-classify node and the output nodes belonging to the acl-plugin. For the first one the less invasive fix is just to initialize that field. For the acl-plugin nodes, rewrite the affected part of the code to use feat_bitmap_get_next_node_index since this is essentially what the conditional in l2_output_dispatch does, and fix the compiler warnings generated. This fix was first made in stable/1701 under commit e7dcee4027854b0ad076101471afdfff67eb9011.

2017-03-03python API: work towards python/vpp api separationKlement Sekera2-7/+36
This change improves vpp_papi behaviour by introducing alternate way of calling vpp APIs. The common code is the same: vpp = VPP(...) vpp.connect(...) Calling VPP API is different, instead of deprecated: vpp.show_version() # deprecated one should write vpp.api.show_version() this allows VPP messages like "connect" and "disconnect" to be used, once the old API is dropped (in 17.07). Also part of this patch is a check for name conflict, to prevent VPP object overwriting its own functionality with generated code based on json files.

With VPP-651, the L2 output config with L2-tag rewrite was not cleared when a sub-interface is deleted. Subsequently, when the same sw_if_index was reused for another interface, the L2 output config with L2-tag rewrite remained on the new interface. On deleting a (sub-)interface which is in L2 mode, it will be changed to L3 mode first to clear any L2 config. The L2 to L3 mode change path did address L2 input config cleanup. It is now fixed to also clear L2 output config. Change-Id: I3352a89d92e1b27340a5adcf75bbaa01a5050c29 Signed-off-by: John Lo <loj@cisco.com>
