2019-09-04memif: always enable zero-copy when creating memif using APIJakub Grajciar1-0/+3

2019-08-22tests: move plugin tests to src/plugins/*/testDave Wallace2-0/+430
- Relocate plugin tests for 'make test' into src/plugins/*/test so that plugin test cases are co-located with the plugin source code.

2019-07-25memif: Fix uninitialized variable as reported by coveritySteven Luong1-1/+2
When mode == ip, the variable next_index is not initialized. Although insde the while loop, ni will be fixed to contain next[0], it is easier to initialize it. Type: fix Change-Id: I6653a958bbc5105e7266bf89e3c8569ff00f0199 Signed-off-by: Steven Luong <sluong@cisco.com>
2019-07-24memif: fix vector overflow when copying stringsBenoît Ganne1-19/+27
When memif sends back socket messages containing strings, we copy vectors into C-string. Unfortunately, most vectors are not null-terminated, causing strncpy() read overflow. Moreover, strncpy() does not null-terminate string in case of max length reached. This patch introduces helpers to safely copy strings from vectors.

2019-07-23api: binary api cleanupDave Barach2-3/+6
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.

2019-07-18vlib: convert frame_index into real pointersAndreas Schultz1-1/+1
The fast path almost always has to deal with the real pointers. Deriving the frame pointer from a frame_index requires a load of the 32bit frame_index from memory, another 64bit load of the heap base pointer and some calculations. Lets store the full pointer instead and do a single 64bit load only. This helps avoiding problems when the heap is grown and frames are allocated below vm->heap_aligned_base.

2019-07-09vat: unload unused vat pluginsDave Barach1-2/+4
If the corresponding vpp plugin is absent, return a non-zero clib_error_t * from vat_plugin_register ("xxx plugin not loaded"). The vat plugin calls dlclose on the vat plugin, and it disappears. Depending on the plugin configuration, this can reduce the vpp virtual size by several gigabytes. Added a VAT_PLUGIN(<plugin-name>) macro to vat_helper_macros, clean up boilerplate vat_plugin_register() implementations. Fixed a number of non-standard vat_plugin_register methods.

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).

2018-09-12Fix create memif socketEd Warnicke1-16/+0
create interface memif [id <id>] [socket-id <socket-id>] ... Can optionally take a socket-id. You create a socket-id with: create memif socket [id <id>] [filename <path>] Unfortunately, this doesn't work because "create memif" was deprecated. It results in: vpp# create memif socket id 0 filename /run/vpp/test.socket command deprecated. Please use 'create interface memif' instead. This fixes it by clipping out the create memif command entirely. Change-Id: If503758706bf758b6cb46e958200527a5856c600 Signed-off-by: Ed Warnicke <hagbard@gmail.com>

gcc8 introduced a new warning (Wstringop-truncation) which in our case is being treated as error.

In version 2 slave is always producer, and in case of master-to-slave rings, slave is responsible for populating ring with empty buffers. As this is major change, we need to bump version number. In addition, descriptor size is reduced to 16 bytes. This change allows zero-copy-slave operation (to be privided in the separate patch).
