bcaf2f08aa PPP, PPPoS: fix memory leak when disconnecting if there are remaining input bytes
Art says:
  pppos_input() can call ppp_input() which can call pppos_disconnect() to
  disconnect the interface.  However, it will continue to read in
  characters and allocate a pbuf from the PBUF_POOL and keep it in
  pppos->in_head and in_tail. When a re-connect happens and pppos_connect()
  is called, this pppos->in_head and in_tail are zeroed, hence a memory
  leak. (This happens with PPP_INPROC_IRQ_SAFE not defined.)

  A fix would be inside pppos_input() to break out of the loop inputting
  characters after calling ppp_input() if pppos->open == 0.  Note that
  the loop is not even entered if pppos->open == 0.

          ppp_input(ppp, inp);
          if(pppos->open == 0) //get out if they disconnected
            break;

Fix it in a similar way which doesn't add new code by moving the
existing pppos->open check inside the byte loop.

1d4cbe768d netif: Add proper lock protect for accessing netif->loop_first
All the reset part of the code accessing netif->loop_first has lock protection,
the only missing part is "while (netif->loop_first != NULL)".
Fix it by adding lock protect around the while loop.

Also convert the code to use while{} loop instead of do .. while{} loop,
then we can avoid NULL test for in pointer in each loop and reduce a level of indent.

8ba7363d11 Optimize passing contiguous nocopy buffers to tcp_write
While TCP_OVERSIZE works only when tcp_write() is used with
TCP_WRITE_FLAG_COPY, this new code achieves
similar benefits for the use case that the caller manages their own
send buffers and passes successive chunks of those to tcp_write()
without TCP_WRITE_FLAG_COPY.

In particular, if a buffer is passed to
tcp_write() that is adjacent in memory to the previously passed
buffer, it will be combined into the previous ROM pbuf reference
whenever possible, thus extending that ROM pbuf rather than allocating
a new ROM pbuf.

For the aforementioned use case, the advantages of this code are
twofold:
1) fewer ROM pbufs need to be allocated to send the same data, and,
2) the MAC layer gets outgoing TCP packets with shorter pbuf chains.

5030fa81a0 bug #49684, api_msg: treat non-blocking ERR_MEM as ERR_WOULDBLOCK
This corrects a case in lwip_netconn_do_writemore() where if a
non-blocking socket receives ERR_MEM in a call to tcp_write(), it would
return ERR_MEM, which would result in ENOMEM coming out of the socket
layer

This case can be gracefully handled by returning ERR_WOULDBLOCK since the
socket is already marked as no longer writable and sent_tcp/poll_tcp will
mark the socket as writable again based on available buffer space

This is very similiar to how ERR_MEM is resolved for blocking sockets

68ec20fffc ipv4/ipv6: restrict loopback-destined traffic
Generally speaking, packets with a loopback destination address -
127.0.0.1 for IPv4 and ::1 for IPv6 - should not be accepted on
non-loopback interfaces.  For IPv4, this is implied by RFC 1122
Sec. 3.2.1.3.  For IPv6, it is mandated by RFC 4291 Sec. 2.5.3.
Failure to perform this filtering may have security implications, as
applications that bind sockets to loopback addresses may not expect
that nodes on the local external network be able to produce traffic
that will arrive at such sockets.

With this patch, lwIP drops packets that are sent to a loopback
address but do not originate from the interface that has the loopback
address assigned to it.  This approach works regardless of whether it
is lwIP or the system using it that implements a loopback netif.  The
only exception that must be made is for configurations that enable
netif packet loopback but disable the lwIP loopback netif: in that
case, loopback packets are routed across non-loopback netifs and would
thus be lost by the new filter as well.

For IPv6, loopback-destined packets are also no longer forwarded; the
IPv4 forwarding code already had a check for that.

As a small performance improvement, the IPv6 link-local/loopback
address check is now performed only once per packet rather than
repeatedly for every candidate netif.

0034abfa45 Always check whether netif_default is NULL
In general, netif_default may be NULL, and various places in the code
already check for this case before attempting to dereference the
netif_default pointer.  Some places do not perform this check though,
and may cause null pointer dereferences if netif_default is not set.
This patch adds NULL checks to those places as well.
