hulk inclusion category: featrue bugzilla: https://atomgit.com/openeuler/kernel/issues/8480 -------------------------------- Add multi port parse to hisock_cmd. Now we can execute the following command to add multi port: hisock_cmd -p 5201 -p 5302 -p 5400-5411 Signed-off-by: Pu Lehui <pulehui@huawei.com> --- samples/bpf/hisock/hisock_cmd.c | 45 +++++++++++++++++---------------- 1 file changed, 23 insertions(+), 22 deletions(-) diff --git a/samples/bpf/hisock/hisock_cmd.c b/samples/bpf/hisock/hisock_cmd.c index 302be05f10f6..52f4d7d7978e 100644 --- a/samples/bpf/hisock/hisock_cmd.c +++ b/samples/bpf/hisock/hisock_cmd.c @@ -30,15 +30,16 @@ #define DEF_BPF_PATH "bpf.o" #define MAX_IF_NUM 8 +#define MAX_PORT_NUM 8 struct { __u32 ifindex[MAX_IF_NUM]; int if_num; - char *port; + char *port[MAX_PORT_NUM]; + int port_num; char *cgrp_path; char *bpf_path; bool unload; - bool help; } hisock; struct hisock_prog_info { @@ -172,7 +173,7 @@ static int parse_port_range(const char *port_str, int map_fd) static int set_speed_port(struct bpf_object *obj) { - int map_fd; + int map_fd, i; map_fd = bpf_object__find_map_fd_by_name(obj, "speed_port"); if (map_fd < 0) { @@ -180,9 +181,11 @@ static int set_speed_port(struct bpf_object *obj) return -1; } - if (hisock.port && parse_port_range(hisock.port, map_fd)) { - fprintf(stderr, "ERROR: failed to update speed port\n"); - return -1; + for (i = 0; i < hisock.port_num; i++) { + if (hisock.port[i] && parse_port_range(hisock.port[i], map_fd)) { + fprintf(stderr, "ERROR: failed to update speed port\n"); + return -1; + } } return 0; @@ -316,11 +319,9 @@ static void do_help(void) static int parse_args(int argc, char **argv) { - char *ifname; int opt; hisock.bpf_path = DEF_BPF_PATH; - hisock.if_num = 0; while ((opt = getopt(argc, argv, "f:c:p:i:uh")) != -1) { switch (opt) { @@ -331,29 +332,34 @@ static int parse_args(int argc, char **argv) hisock.cgrp_path = optarg; break; case 'p': - hisock.port = optarg; + hisock.port[hisock.port_num] = optarg; + hisock.port_num++; break; case 'i': - ifname = optarg; - hisock.ifindex[hisock.if_num] = if_nametoindex(ifname); + hisock.ifindex[hisock.if_num] = if_nametoindex(optarg); hisock.if_num++; break; case 'u': hisock.unload = true; break; case 'h': - hisock.help = true; - break; + do_help(); + exit(0); default: fprintf(stderr, "ERROR: unknown option %c\n", opt); return -1; } } - if (hisock.cgrp_path == NULL || - hisock.if_num == 0 || - (!hisock.unload && - hisock.port == NULL)) { + if (hisock.unload && + (hisock.cgrp_path == NULL || hisock.if_num == 0)) { + do_help(); + return -1; + } + + if (!hisock.unload && + (hisock.cgrp_path == NULL || hisock.if_num == 0 || + hisock.port_num == 0)) { do_help(); return -1; } @@ -368,11 +374,6 @@ int main(int argc, char **argv) return -1; } - if (hisock.help) { - do_help(); - return 0; - } - if (hisock.unload) { if (detach_progs()) { fprintf(stderr, "ERROR: failed to detach progs\n"); -- 2.34.1
