[Bug 61968] New: ab fails to connect to localhost (111)


https://bz.apache.org/bugzilla/show_bug.cgi?id=61968

            Bug ID: 61968
           Summary: ab fails to connect to localhost (111)
           Product: Apache httpd-2
           Version: 2.4.29
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Core
          Assignee: bugs@xxxxxxxxxxxxxxxx
          Reporter: yuri.kanivetsky@xxxxxxxxx
  Target Milestone: ---

The following command fails:

$ ab -n 1 localhost:8000/
...
Benchmarking localhost (be patient)...apr_socket_recv: Connection refused (111)

But this one succeeds:

$ ab -n 1 127.0.0.1:8000/

In /etc/hosts I have:

127.0.0.1   localhost.localdomain   localhost
::1     localhost.localdomain   localhost

The issue here is caused by ab taking the first result returned by
apr_sockaddr_info_get:

https://github.com/apache/httpd/blob/2.4.29/support/ab.c#L1835-L1837

But apr_sockaddr_info_get returns a list. If it were to try the second sockaddr
structure, it would connect. This way it works:


    rv = apr_sockaddr_info_get(&sa, REMOTE_HOST, APR_UNSPEC, REMOTE_PORT, 0,
mp);
    if (rv != APR_SUCCESS) {
        return rv;
    }

    for ( ; sa; sa = sa->next) {
        rv = apr_socket_create(&s, sa->family, SOCK_STREAM, APR_PROTO_TCP, mp);
        if (rv != APR_SUCCESS) {
            return rv;
        }

        apr_socket_opt_set(s, APR_SO_NONBLOCK, 1);
        apr_socket_timeout_set(s, SOCK_TIMEOUT);

        rv = apr_socket_connect(s, sa);
        if (rv == ECONNREFUSED) {
            continue;
        } else if (rv == APR_SUCCESS) {
            break;
        } else {
            return rv;
        }
    }

    apr_socket_opt_set(s, APR_SO_NONBLOCK, 0);
    apr_socket_timeout_set(s, SOCK_TIMEOUT);


Other tools (like, curl, wget, w3m) deal with it just fine.

P.S. A couple of links just in case
