+Subject: [PATCH] resolve: Use sockaddr pointer type for bind()
+
+bind() expects sockaddr* but SERVER_ADDRESS is sockaddr_in type struct
+
+Fixes errors with clang e.g.
+
+../git/src/resolve/test-resolved-stream.c:112:32: error: incompatible pointer types passing 'struct sockaddr_in *' to parameter of type 'const struct sockaddr *' [-Werror,-Wincompatible-pointer-types]
+        assert_se(bind(bindfd, &SERVER_ADDRESS, sizeof(SERVER_ADDRESS)) >= 0);
+                               ^~~~~~~~~~~~~~~
+../git/src/resolve/test-resolved-stream.c:251:39: error: incompatible pointer types passing 'struct sockaddr_in *' to parameter of type 'const struct sockaddr *' [-Werror,-Wincompatible-pointer-types]
+                r = connect(clientfd, &SERVER_ADDRESS, sizeof(SERVER_ADDRESS));
+
+Upstream-Status: Submitted [https://github.com/systemd/systemd/pull/23281]
