2018-12-05Improve strncpy_s src/dst overlap checkDave Barach1-2/+12
Let m = user estimate of the (max) src string length, low = smaller address of (src, dst), hi = larger address (src, dst). if (low + (m - 1) >= hi), we have a *potential* overlapping copy which is not allowed. Before we declare overlap - and return an error - retry the check with m = actual src string length. The resulting "test string" failure affected aarch64 (only) because of differences in test code stack variable placement / alignment.

2018-12-04Add VNET_BUFFER_F_AVAIL definitionsDave Barach2-1/+26
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.

2018-12-02vppinfra: c11 safe string functionsSteven4-25/+2682
Add memcmp_s, strcmp_s, strncmp_s, strcpy_s, strncpy_s, strcat_s, strncat_s, strtok_s, strnlen_s, and strstr_s C11 safe string API. For migrating extant unsafe API, add also the corresponding macro version of each safe API, clib_memcmp, clib_strcmp, etc. In general, the benefits of the safe string APIs are to provide null pointer checks, add additional argument to specify the string length of the passed string rather than relying on the null terminated character, and src/dest overlap checking for the the string copy operations. The macro version of the API takes the same number of arguments as the unsafe API to provide easy migration. However, it does not usually provide the full aformentioned benefits. In some cases, it is necessary to move to the safe API rather than using the macro in order to avoid some unpredictable problems such as accessing memory beyond what it is intended due to the lack of the passed string length. dbarach: add a "make test" vector, and a doxygen file header cookie.

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.
