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.

2019-06-07bfd: midchain adjacency supportMatthew G Smith1-10/+51
Support an adjacency with lookup_next_index of IP_LOOKUP_NEXT_MIDCHAIN so tunnel interfaces can have BFD configured on them. Also, check if the interface a session is configured on is up and skip assembling the packet and calculating the checksum if the interface is down.

2019-02-14Add -fno-common compile optionBenoît Ganne1-1/+1
-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).

2018-08-29Address bfd rpc scale issuesDave Barach3-24/+280
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.

2018-01-23VPPAPIGEN: vppapigen replacement in Python PLY.Ole Troan1-1/+1
This is a version of the VPP API generator in Python PLY. It supports the existing language, and has a plugin architecture for generators. Currently C and JSON are supported. Changes: - vl_api_version to option version = "major.minor.patch" - enum support - Added error checking and reporting - import support (removed the C pre-processor) - services (tying request/reply together) Version: option version = "1.0.0"; Enum: enum colours { RED, BLUE = 50, }; define foo { vl_api_colours_t colours; }; Services: service { rpc foo returns foo_reply; rpc foo_dump returns stream foo_details; rpc want_stats returns want_stats_reply events ip4_counters, ip6_counters; }; Future planned features: - unions - bool, text - array support (including length) - proto3 output plugin - Refactor C/C++ generator as a plugin - Refactor Java generator as a plugin Change-Id: Ifa289966c790e1b1a8e2938a91e69331e3a58bdf Signed-off-by: Ole Troan <ot@cisco.com>

This does not update api client code. In other words, if the client assumes the transport is shmem based, this patch does not change that. Furthermore, code that checks queue size, for tail dropping, is not updated.

2017-12-16Use crc32 wrapper (VPP-1086)Gabriel Ganne1-4/+4
This allows arm platforms to also take advantage of crc32 hardware acceleration. * add a wrapper for crc32_u64. It's the only one really used. Using it instead of a call to clib_crc32c() eases building symmetrical hash functions. * replace #ifdef on SSE4 by a test on clib_crc32c_uses_intrinsics.

Add a way to toggle on and off a warning for a specific section of code. This supports clang and gcc, and has no effect for any other compilers.

This field is used only when VLIB_BUFFER_TOTAL_LENGTH_VALID and VLIB_BUFFER_NEXT_PRESENT are both set. - free_list_index is now stored in 4bits inside flags, which allows up to 16 free lists.

2017-04-06BFD-FIB interactionsNeale Ranns3-2/+73
- single-hop BFD: attach a delegate to the appropriate adjacency - multi-hop BFD [not supported yet]: attach a delegate to the FIB entry. adjacency/fib_entry state tracks the BFD session state. when the state is down the object does not contribute forwarding hence and hence dependent objects will not use it. For example, if a route is ECMP via two adjacencies and one of them is BFD down, then only the other is used to forward (i.e. we don't drop half the traffic).
