85cf00791c mem: avoid memzone/mempool/ring name truncation
Check the return value of snprintf to ensure that the name of
the object is not truncated.

By the way, update the test to avoid to trigger an error in
that case.

a2ccd6b742 mempool: remove macro to check if contiguous
This commit removes MEMPOOL_IS_CONTIG().

The next commits will change the behavior of the mempool library so that
the objects will never be allocated in the same memzone than the mempool
header. Therefore, there is no reason to keep this macro that would
always return 0.

This macro was only used in app/test.

213af31e09 mempool: reduce structure size if no cache needed
The rte_mempool structure is changed, which will cause an ABI change
for this structure. Providing backward compat is not reasonable
here as this structure is used in multiple defines/inlines.

Allow mempool cache support to be dynamic depending on if the
mempool being created needs cache support. Saves about 1.5M of
memory used by the rte_mempool structure.

Allocating small mempools which do not require cache can consume
larges amounts of memory if you have a number of these mempools.

411c22d4e0 app/test: fix memory corruption in reentrancy autotest
The mempool element size is set to 0, but 4 bytes are written in
my_obj_init():

  uint32_t *objnum = obj;
  memset(obj, 0, mp->elt_size);
  *objnum = i;

Change the MEMPOOL_ELT_SIZE constant to sizeof(uint32_t). This fixes
memory corruptions since we were writing outside of the object
boundaries.

2c007ea106 app/test: fix array overflow warning with gcc 4.5
DPDK/app/test/test_cryptodev.c:

DPDK/x86_64-ivshmem-linuxapp-gcc/include/rte_memcpy.h:796:14: error:

In lines like:
    rte_memcpy(sym_op->cipher.iv.data, iv, iv_len);
when "iv" is 64 bytes long array, and "iv_len" is "unsigned int",
compiler tries to evaluate also a code for array size larger than 255 bytes
long and reports error "array subscript is above array bounds" in line:
	rte_memcpy.h:796
    rte_mov128((uint8_t *)dst + 128, (const uint8_t *)src + 128);
caused by evaluation to:
    rte_mov128((uint8_t *)sym_op->cipher.iv.data + 128, (const uint8_t *)iv

where "iv" is 64 bytes long buffer and "iv + 128" point out of it, gcc 4.5.

Using uint8_t as a size of copied block prevents to evaluate in rte_memcpy

a7e88f1782 app/test: fix reentrancy autotest
The previous code in func_reentrancy autotest was doing in parallel
something close to:

  name = "common_name";
  do several times {
      obj = allocate_an_object(name)   // obj = ring, mempool, hash, lpm, ...
      if (obj == NULL && lookup(name) == NULL)
          return TEST_FAIL;
  }

This code is not safe. For instance:

   mempool_create() is called on core 0, it creates a ring. At the same
   time on core 1, mempool_create() is called too and the creation of the
   ring fails (EEXIST). But the mempool lookup can fail on core 1 if
   the mempool is not added in the list by core 0.

This commit fixes the func_reentrancy autotest that now works with all
tested class of objects.

1aadacb5b0 hash: fix allocation of an existing object
Change rte_hash*_create() functions to return NULL and set rte_errno to
EEXIST when the object name already exists. This is the behavior
described in the API documentation in the header file.

These functions were returning a pointer to the existing object in that
case, but it is a problem as the caller did not know if the object had
to be freed or not.

Doing this change also makes the hash API more consistent with the other

- Authentication then Cipher

processing are not actually modified and are stored in a queue pairs processed
packets ring ready for collection when rte_cryptodev_burst_dequeue() is called.
