2019-01-18Fix GCC 8 compiler warnings on strncpy's truncated copy on debian distroSteven Luong1-2/+2
For some reason, GCC 8 in debian is pickier than GCC 8 in ubuntu. It complains about things in strncpy like this /home/sluong/vpp/src/vlib/linux/pci.c:485:7: error: ‘strncpy’ output may be truncated copying 15 bytes from a string of length 255 [-Werror=stringop-truncation] strncpy (ifr.ifr_name, e->d_name, sizeof (ifr.ifr_name) - 1); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /home/sluong/vpp/src/vlib/linux/pci.c: At top level: It also complains similar things in string_test.c The fix in pci.c is to convert strncpy to use clib_strncpy The fix in string_test.c is condiational compile the complained code for GCC 8.

2019-01-17vmbus: fix strncpy related warningsStephen Hemminger1-4/+4
The code that was manipulating interface names with ifreq was causing warnings about possible truncation and non terminated strings. These are warnings only since kernel would allow a interface name > 15 characters anyway.

2019-01-17pci: fix strncpy warningsStephen Hemminger1-4/+4
Doing strncpy(ifr.ifr_name, s, sizeof(ifr.ifr_name)) will cause a warning about string truncation with GCC 8 (and other tools). Fix this by using sizeof(ifr.ifr_name) - 1. Also, there is no need to manually zero the end of the string since the whole ifr structure is already zeroed by memset.

2019-01-07Handle buffer alloc failure in vlib_buffer_add_dataDave Barach2-8/+9
It's not OK to crash due to a transient buffer allocation failure. Return 1 if the requested operation failed, otherwise 0. Buffer index parameter change to a value-result, so the caller can differentiate between partial and complete allocation failure: callers which request an initial allocation (inbound bi = ~0) need to check the (out) value to decide whether or not to call vlib_buffer_free(...).

2018-12-04Add VNET_BUFFER_F_AVAIL definitionsDave Barach1-0/+1
Add a check to make sure that the vlib and vnet buffer flag bit definitions do not overlap. The VNET_BUFFER_F_AVAIL1...8 definitions allow out-of-tree codes to: #define VNET_BUFFER_F_MY_USECASE VNET_BUFFER_F_AVAIL1 and so on. This avoids introducing irrelevant and/or proprietary bit definitions into vnet/buffer.h, and hopefully minimizes merge pain for everyone involved.

The buffer index allows downstream consumers of these data to easily filter/track single packets as they traverse the forwarding graph. FWIW, the 32-bit buffer index is stored in big endian format. As of this writing, major version = 1, minor version = 0. Nstrings will be either 4 or 5. Here is the current set of protocol hints: typedef enum { VLIB_NODE_PROTO_HINT_NONE = 0, VLIB_NODE_PROTO_HINT_ETHERNET, VLIB_NODE_PROTO_HINT_IP4, VLIB_NODE_PROTO_HINT_IP6, VLIB_NODE_PROTO_HINT_TCP, VLIB_NODE_PROTO_HINT_UDP, VLIB_NODE_N_PROTO_HINTS, } vlib_node_proto_hint_t; Example: VLIB_NODE_PROTO_HINT_IP6 means that the first octet of packet data SHOULD be 0x60, and should begin an ipv6 packet header.
