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>

2018-08-13Multiarch handling in different constructor macrosDamjan Marion2-13/+8
This significantly reduces need for ... in multiarch code. Simply constructor macros will jost create static unused entry if CLIB_MARCH_VARIANT is defined and that will be optimized out by compiler.

2018-06-27gcc8 and Wstringop-truncationMarco Varlese1-1/+1
gcc8 introduced a new warning (Wstringop-truncation) which in our case is being treated as error. Disabling the warning globally might introduce bugs related to string truncation which are not desired by the developer (e.g. bug). Instead, this patch disables the warning only for those occurences which have been verified to be non-bugs but the desired behaviour as per developer will.

Three choices: add CLIB_CACHE_LINE_ALIGN_MARK(align_me) at the end of structures, manually pad to an even divisor or multiple of the alignment request, or use plain vectors/pools. static assert for enforcement.

private header size allows to reserve firs X bytes of payload to be considered as private metadata.

2018-03-22memif: version 2Damjan Marion6-486/+558
In version 1 of the protocol sender was always ring producer and receiver was consumer. 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).

2018-02-27memif: Fix a message initialization problem in VATJon Loeliger1-3/+2
The VAT calls to MEMIF_SOCKET_FILENAME_ADD_DEL erroneously cleared the message memory after the M() macro call and thus lost their message id. Don't do that.

2018-01-29memif: Add new API calls to manage memif socket names.Jon Loeliger7-102/+647
New API calls and corresponding CLI commands allow the user to manage the socket filenames for memif connections using: vppctl# create memif id <u32> filename <socket-filename> vppctl# delete memif id <u32> and then referencing it later in a memif interface: vppctl# create memif <u32> socket-id <id> mode <mode> <master|slave> ... Corresponding VAT cli entries have also been added. The default memif socket file at id 0 are still always present. The existing memif create/delete CLI commands have been slightly altered into the new syntax: vppctl# create interface memif ... vppctl# delete interface memif ...

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>
2018-01-11api: remove transport specific code from handlersFlorin Coras1-6/+6
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. Done for the following apis: Plugins - acl - gtpu - memif - nat - pppoe VNET - bfd - bier - tapv2 - vhost user - dhcp - flow - geneve - ip - punt - ipsec/ipsec-gre - l2 - l2tp - lisp-cp/one-cp - lisp-gpe - map - mpls - policer - session - span - udp - tap - vxlan/vxlan-gpe - interface VPP - api/api.c OAM - oam_api.c Stats - stats.c Change-Id: I0e33ecefb2bdab0295698c0add948068a5a83345 Signed-off-by: Florin Coras <fcoras@cisco.com>
2018-01-11Remove vpp_api_test interface name filter catalogDave Barach1-0/+1
If I remember correctly, I added the interface name filter catalog to avoid cluttering up the vat interface table with [unused] packet generator interfaces. Since we no longer create pg interfaces we're not planning to use, the filter catalog does more harm than good. Every new interface name prefix would have had to be added to the list, and folks wouldn't likely know they should do that...

1. coverity complains about "buffer not null terminated" for strncpy because we pass the size of the destination to the call which is equal to the true size of the destination. We subtract 1 for the size to accommodate the null like all other places are already doing it. 2. Add a check to tx_queues in memif_interface_tx_inline to avoid "divide by zero". 3. To avoid null pointer dereference in memif_create_if, change the goto done rather than goto error and spit a more meaningful error rather than silent about it. 4.
