[libvirt] [PATCH] virSocketAddrIsWildcard: Drop IN6_IS_ADDR_UNSPECIFIED

There's this macro IN6_IS_ADDR_UNSPECIFIED which seems to be portable, but it is not. On other architectures many errors are produced, e.g. on my ARM box I get: CC libvirt_util_la-virsocketaddr.lo util/virsocketaddr.c: In function 'virSocketAddrIsWildcard': util/virsocketaddr.c:244:16: error: cast increases required alignment of target type [-Werror=cast-align] util/virsocketaddr.c: At top level: cc1: error: unrecognized command line option "-Wno-unused-command-line-argument" [-Werror] cc1: all warnings being treated as errors Hence, we should drop its usage and move to memcmp instead. --- src/util/virsocketaddr.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/src/util/virsocketaddr.c b/src/util/virsocketaddr.c index e84c58e..1cefda7 100644 --- a/src/util/virsocketaddr.c +++ b/src/util/virsocketaddr.c @@ -241,7 +241,8 @@ virSocketAddrIsWildcard(const virSocketAddrPtr addr) return memcmp(&addr->data.inet4.sin_addr.s_addr, &tmp, sizeof(addr->data.inet4.sin_addr.s_addr)) == 0; case AF_INET6: - return IN6_IS_ADDR_UNSPECIFIED(&addr->data.inet6.sin6_addr.s6_addr); + return memcmp(addr->data.inet6.sin6_addr.s6_addr, &in6addr_any, + sizeof(addr->data.inet6.sin6_addr.s6_addr)) == 0; } return false; } -- 1.8.1.5
