  "message": "Core: skip special buffers on writing (ticket #981).\n\nA special last buffer with cl-\u003ebuf-\u003epos set to NULL can be present in\na chain when writing request body if chunked encoding was used.  This\nresulted in a NULL pointer dereference if it happened to be the only\nbuffer left after a do...while loop iteration in ngx_write_chain_to_file().\n\nThe problem originally appeared in nginx 1.3.9 with chunked encoding\nsupport.  Additionally, rev. 3832b608dc8d (nginx 1.9.13) changed the\nminimum number of buffers to trigger this from IOV_MAX (typically 1024)\nto NGX_IOVS_PREALLOCATE (typically 64).\n\nFix is to skip such buffers in ngx_chain_to_iovec(), much like it is\ndone in other places.\n",
