Upon review, it was found that the model for malloc() was incorrect. In addition, several general purpose memory allocation functions were missing models: * kmem_vasprintf() * kmem_asprintf() * kmem_strdup() * kmem_strfree() * spl_vmem_alloc() * spl_vmem_zalloc() * spl_vmem_free() * calloc() As an experiment to try to find more bugs, some less than general purpose memory allocation functions were also given models: * zfsvfs_create() * zfsvfs_free() * nvlist_alloc() * nvlist_dup() * nvlist_free() * nvlist_pack() * nvlist_unpack() Finally, the models were improved using additional coverity primitives: * __coverity_negative_sink__() * __coverity_writeall0__() * __coverity_mark_as_uninitialized_buffer__() * __coverity_mark_as_afm_allocated__() In addition, an attempt to inform coverity that certain modelled functions read entire buffers was used by adding the following to certain models: int first = buf[0]; int last = buf[buflen-1]; It was inspired by the QEMU model file. No additional false positives were found by this, but it is believed that the more accurate model file will help to catch false positives in the future.
