[libqb] Unlink of files bound to sockets

[Grüninger, Andreas (LGL Extern)]

In qb_ipcc_us_sock_close  nd qb_ipcs_us_withdraw  of lib/ipc_setup.c sockets are closed.
Is there a reason why the files bound to the sockets are not deleted with unlink?
Is unlinking not necessary with Linux?
I found thousands of files in statedir=/var/corosync/run

I tried this and it seems to work without errors.

void
qb_ipcc_us_sock_close(int32_t sock)
{
  #ifdef QB_SOLARIS
  struct sockaddr_un un_addr;
  socklen_t un_addr_len = sizeof(struct sockaddr_un);
  #endif
  shutdown(sock, SHUT_RDWR);
  #ifdef QB_SOLARIS
  if (getsockname(sock, (struct sockaddr *)&un_addr, &un_addr_len) == 0) {
    if(strstr(un_addr.sun_path,"-") != NULL) {
      qb_util_log(LOG_DEBUG, "un_addr.sun_path=%s", un_addr.sun_path);
      unlink(un_addr.sun_path);
    }
  } else {
    qb_util_log(LOG_DEBUG, "getsockname returned errno=%d", errno);
  }
  #endif
  close(sock);
}
