            Bug ID: 1553
           Summary: free called on rte_malloc block in vhost
           Product: DPDK
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: major
          Priority: Normal
         Component: vhost/virtio
          Assignee: dev@dpdk.org
          Reporter: stephen@networkplumber.org
  Target Milestone: ---

If Gcc function attributes are added to rte_malloc, the compiler is able to
detect bugs where free is called on rte_malloc memory such as:

[2737/2957] Compiling C object
examples/dpdk-vhost_blk.p/vhost_blk_vhost_blk.c.o
In function ‘vhost_blk_bdev_construct’,
    inlined from ‘vhost_blk_ctrlr_construct.constprop’ at
../examples/vhost_blk/vhost_blk.c:826:16:
../examples/vhost_blk/vhost_blk.c:779:17: warning: ‘free’ called on pointer
returned from a mismatched allocation function [-Wmismatched-dealloc]
  779 |                 free(bdev);
      |                 ^~~~~~~~~~
../examples/vhost_blk/vhost_blk.c:761:16: note: returned from ‘rte_zmalloc’
  761 |         bdev = rte_zmalloc(NULL, sizeof(*bdev), RTE_CACHE_LINE_SIZE);
      |                ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
