In commit 80da7efbb4c4 ("eal: annotate allocation functions")

of the functions in DPDK but missed the case of data allocated
by BPF load functions.Signed-off-by: Stephen Hemminger <step...@networkplumber.org> --- lib/bpf/rte_bpf.h | 11 ++++++++--- 1 file changed, 8 insertions(+), 3 deletions(-) diff --git a/lib/bpf/rte_bpf.h b/lib/bpf/rte_bpf.h index 80ebb0210f..309d84bc51 100644 --- a/lib/bpf/rte_bpf.h +++ b/lib/bpf/rte_bpf.h @@ -18,6 +18,7 @@ #include <rte_common.h> #include <rte_mbuf.h> +#include <rte_malloc.h> #include <bpf_def.h> #ifdef __cplusplus @@ -128,7 +129,8 @@ rte_bpf_destroy(struct rte_bpf *bpf); * - ENOMEM - can't reserve enough memory */ struct rte_bpf * -rte_bpf_load(const struct rte_bpf_prm *prm); +rte_bpf_load(const struct rte_bpf_prm *prm) + __rte_malloc __rte_dealloc(rte_bpf_destroy, 1); /** * Create a new eBPF execution context and load BPF code from given ELF @@ -152,7 +154,9 @@ rte_bpf_load(const struct rte_bpf_prm *prm); */ struct rte_bpf * rte_bpf_elf_load(const struct rte_bpf_prm *prm, const char *fname, - const char *sname); + const char *sname) + __rte_malloc __rte_dealloc(rte_bpf_destroy, 1); + /** * Execute given BPF bytecode. * @@ -228,7 +232,8 @@ struct bpf_program; * - ENOTSUP - operation not supported */ struct rte_bpf_prm * -rte_bpf_convert(const struct bpf_program *prog); +rte_bpf_convert(const struct bpf_program *prog) + __rte_malloc __rte_dealloc_free; #ifdef __cplusplus } -- 2.47.2
