From 2aeb201c9751d4ee82978c623310e14b9e831b94 Mon Sep 17 00:00:00 2001 From: Denys Vlasenko Date: Tue, 17 Apr 2018 12:43:54 +0200 Subject: libbb: new option FEATURE_ETC_SERVICES: if off, /etc/services reads often avoided In practice, "wget http://host.com/" always uses port 80. People explicitly set non-standard ports via options or parameters ("telnet 1.2.3.4 567" or "telnet 1.2.3.4 ftp") instead of modifying /etc/services. function old new delta telnet_main 1466 1464 -2 rdate_main 215 198 -17 fakeidentd_main 269 252 -17 parse_url 459 392 -67 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/4 up/down: 0/-103) Total: -103 bytes Signed-off-by: Denys Vlasenko --- include/libbb.h | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'include/libbb.h') diff --git a/include/libbb.h b/include/libbb.h index 646c58bf2..a605c7f03 100644 --- a/include/libbb.h +++ b/include/libbb.h @@ -640,6 +640,11 @@ int setsockopt_bindtodevice(int fd, const char *iface) FAST_FUNC; int bb_getsockname(int sockfd, void *addr, socklen_t addrlen) FAST_FUNC; /* NB: returns port in host byte order */ unsigned bb_lookup_port(const char *port, const char *protocol, unsigned default_port) FAST_FUNC; +#if ENABLE_FEATURE_ETC_SERVICES +# define bb_lookup_std_port(portstr, protocol, portnum) bb_lookup_port(portstr, protocol, portnum) +#else +# define bb_lookup_std_port(portstr, protocol, portnum) (portnum) +#endif typedef struct len_and_sockaddr { socklen_t len; union { -- cgit v1.2.3
