Log: [libcasper] Update cap_dns API to not trigger unused variable warnings when disabled When compiling without casper these API calls result in unused variable warnings. Using #defines was lovely in the past but unfortunately it triggers warnings which can cascade into errors. Instead, just inline with some fallthrough functions and keep things happy. Tested: * gcc-6 targeting mips32, with casper disabled Reviewed by: emaste Differential Revision: https://reviews.freebsd.org/D26762 Modified: head/lib/libcasper/services/cap_dns/cap_dns.h Modified: head/lib/libcasper/services/cap_dns/cap_dns.h ============================================================================== --- head/lib/libcasper/services/cap_dns/cap_dns.h Tue Oct 13 22:20:03 2020 (r366687) +++ head/lib/libcasper/services/cap_dns/cap_dns.h Tue Oct 13 22:49:43 2020 (r366688) @@ -39,6 +39,15 @@ #include <sys/cdefs.h> #include <sys/socket.h> /* socklen_t */ +/* + * Pull these in if we're just inlining calls to the underlying + * libc functions. + */ +#ifndef WITH_CASPER +#include <sys/types.h> +#include <netdb.h> +#endif /* WITH_CASPER */ + struct addrinfo; struct hostent; @@ -64,17 +73,62 @@ int cap_dns_family_limit(cap_channel_t *chan, const in __END_DECLS #else -#define cap_gethostbyname(chan, name) gethostbyname(name) -#define cap_gethostbyname2(chan, name, type) gethostbyname2(name, type) -#define cap_gethostbyaddr(chan, addr, len, type) gethostbyaddr(addr, len, type) -#define cap_getaddrinfo(chan, hostname, servname, hints, res) \ - getaddrinfo(hostname, servname, hints, res) -#define cap_getnameinfo(chan, sa, salen, host, hostlen, serv, servlen, flags) \ - getnameinfo(sa, salen, host, hostlen, serv, servlen, flags) +static inline struct hostent * +cap_gethostbyname(cap_channel_t *chan __unused, const char *name) +{ -#define cap_dns_type_limit(chan, types, ntypes) (0) -#define cap_dns_family_limit(chan, families, nfamilies) (0) -#endif + return (gethostbyname(name)); +} + +static inline struct hostent * +cap_gethostbyname2(cap_channel_t *chan __unused, const char *name, int type) +{ + + return (gethostbyname2(name, type)); +} + +static inline struct hostent * +cap_gethostbyaddr(cap_channel_t *chan __unused, const void *addr, + socklen_t len, int type) +{ + + return (gethostbyaddr(addr, len, type)); +} + +static inline int cap_getaddrinfo(cap_channel_t *chan __unused, + const char *hostname, const char *servname, const struct addrinfo *hints, + struct addrinfo **res) +{ + + return (getaddrinfo(hostname, servname, hints, res)); +} + +static inline int cap_getnameinfo(cap_channel_t *chan __unused, + const struct sockaddr *sa, socklen_t salen, char *host, size_t hostlen, + char *serv, size_t servlen, int flags) +{ + + return (getnameinfo(sa, salen, host, hostlen, serv, servlen, flags)); +} + +static inline int +cap_dns_type_limit(cap_channel_t *chan __unused, + const char * const *types __unused, + size_t ntypes __unused) +{ + + return (0); +} + +static inline int +cap_dns_family_limit(cap_channel_t *chan __unused, + const int *families __unused, + size_t nfamilies __unused) +{ + + return (0); +} +#endif /* WITH_CASPER */ #endif /* !_CAP_DNS_H_ */ _______________________________________________ svn-src-all@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
