[lwip-users] Maybe a bug in tcpip_apimsg()

[justin_wu]

Function should return when tcpip_apimsg() malloc a memp failed, but in the
fact the client task send this apimsg was blocked on the
apimsg->msg.conn->mbox, I think this maybe a bug, so I do a little
modification:

void
tcpip_apimsg(struct api_msg *apimsg)
{
  struct tcpip_msg *msg;
  msg = memp_mallocp(MEMP_TCPIP_MSG);
  if (msg == NULL) {
    memp_free(MEMP_API_MSG, apimsg);
    sys_mbox_post(apimsg->msg.conn->mbox, NULL);   /* Un-block client task
at this time */
    return;
  }
  msg->type = TCPIP_MSG_API;
  msg->msg.apimsg = apimsg;
  sys_mbox_post(mbox, msg);
}
