It could be unsigned int, but in future commits\nwe'll share with net/tap.c the common function which will return\nnumber of queues or negative error. So, let's simply use int for\nqueues-related variables, that simplifies things.\n\nSigned-off-by: Vladimir Sementsov-Ogievskiy <vsementsov@yandex-team.ru>\n---\n net/af-xdp.c | 17 +++++++++--------\n 1 file changed, 9 insertions(+), 8 deletions(-)", "diff": "diff --git a/net/af-xdp.c b/net/af-xdp.c\nindex 14f302ea21..ff1cb30a98 100644\n--- a/net/af-xdp.c\n+++ b/net/af-xdp.c\n@@ -442,14 +442,14 @@ static NetClientInfo net_af_xdp_info = {\n };\n \n static int *parse_socket_fds(const char *sock_fds_str,\n- int64_t n_expected, Error **errp)\n+ int n_expected, Error **errp)\n {\n gchar **substrings = g_strsplit(sock_fds_str, \":\", -1);\n- int64_t i, n_sock_fds = g_strv_length(substrings);\n+ int i, n_sock_fds = g_strv_length(substrings);\n int *sock_fds = NULL;\n \n if (n_sock_fds != n_expected) {\n- error_setg(errp, \"expected %\"PRIi64\" socket fds, got %\"PRIi64,\n+ error_setg(errp, \"expected %d socket fds, got %d\",\n n_expected, n_sock_fds);\n goto exit;\n }\n@@ -484,7 +484,7 @@ int net_init_af_xdp(const Netdev *netdev,\n unsigned int ifindex;\n uint32_t prog_id = 0;\n g_autofree int *sock_fds = NULL;\n- int64_t i, queues;\n+ int i, queues;\n Error *err = NULL;\n AFXDPState *s;\n bool inhibit;\n@@ -496,13 +496,14 @@ int net_init_af_xdp(const Netdev *netdev,\n return -1;\n }\n \n- queues = opts->has_queues ? opts->queues : 1;\n- if (queues < 1) {\n+ if (opts->has_queues && (opts->queues < 1 || opts->queues > INT_MAX)) {\n error_setg(errp, \"invalid number of queues (%\" PRIi64 \") for '%s'\",\n- queues, opts->ifname);\n+ opts->queues, opts->ifname);\n return -1;\n }\n \n+ queues = opts->has_queues ? opts->queues : 1;\n+\n inhibit = opts->has_inhibit && opts->inhibit;\n if (inhibit && !opts->sock_fds && !opts->map_path) {\n error_setg(errp, \"'inhibit=on' requires 'sock-fds' or 'map-path'\");\n@@ -537,7 +538,7 @@ int net_init_af_xdp(const Netdev *netdev,\n \n for (i = 0; i < queues; i++) {\n nc = qemu_new_net_client(&net_af_xdp_info, peer, \"af-xdp\", name);\n- qemu_set_info_str(nc, \"af-xdp%\"PRIi64\" to %s\", i, opts->ifname);\n+ qemu_set_info_str(nc, \"af-xdp%d to %s\", i, opts->ifname);\n nc->queue_index = i;\n \n if (!nc0) {\n", "prefixes": [ "v3", "01/12" ] }
