Doing a search for "INADDR" in ip(7) manual page should be sufficient to find occurrences. Below follows kinda a C file. It contains a description and the code which shows the BUG. ip7_manpage_bug.c /* * 09/11/2017 * confirms the BUG in ip(7) manual page * * Description: A BUG in ip(7) man page that says INADDR_* values can be * assigned directly, whereas they must be assigned with htonl() * htonl = host to network long, or host byte order to network byte order * conversion on uint32_t type * * An excerpt of what is wrong: "The s_addr member of struct in_addr contains * the host interface address in network byte order. in_addr should be assigned * one of the INADDR_* values [...]" * * See RATIONALE section of reference #0 for the note from the standard * * references * #0: * http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/netinet_in.h.html */ #include <arpa/inet.h> /* inet_addr() htonl() */ #include <inttypes.h> /* PRIu32 */ #include <netinet/in.h> /* INADDR_* */ #include <stdio.h> /* printf() :-) */ #define LOOPBACK_ADDRESS "127.0.0.1" int main(void) { /* uint32_t as defined in reference #0 */ uint32_t addr; addr = inet_addr(LOOPBACK_ADDRESS); printf("inet_addr: %" PRIu32 "\n" "htonl(INADDR_LOOPBACK): %" PRIu32 "\n" "INADDR_LOOPBACK: %" PRIu32 "\n", addr, htonl(INADDR_LOOPBACK), INADDR_LOOPBACK); return 0; } -- Ricardo Biehl Pasquali -- To unsubscribe from this list: send the line "unsubscribe linux-man" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
