[lwip-devel] [bug #11400] ARP multi-packet-queue modifies TCP unsent/unacked segment packet pbuf chain into packet queue

[Simon Goldschmidt]

Follow-up Comment #10, bug #11400 (project lwip):

Hey, someone tested it! Thanks for the comment, that happens if you use
cut&paste...
I've corrected it in CVS HEAD

But I've got another (code-reading) problem with that patch (I want to test
that on the weekend some time): in etharp.c, If you enqueue pbufs,
pbuf_take() is called (which is now the only call to that function, by the
way). There, PBUF_REFs are copied to new PBUF_RAMs. I think we still corrupt
a given pbuf chain in that case.

Maybe a solution would be to copy enqueued pbufs to a new location no matter
what type they are?

We don't event need pbuf_take any more, do we? Also, we don't need
pbuf_queue() and pbuf_dequeue() any more since it was #if ARP_QUEUEING
