[Qemu-devel] [Bug 1703147] [NEW] Xfer:features:read truncating xml sent to gdb frontends

[Duane Voth]

Public bug reported:

Around line 1326 in gdbstub.c:

            if (len > (MAX_PACKET_LENGTH - 5) / 2)
                len = (MAX_PACKET_LENGTH - 5) / 2;

is truncating processor reg description xml files longer than 2045
bytes.  Deleting these lines works for my immediate need, but they seem
to be trying to fix some buffer overrun condition so I won't offer a
patch until we understand their purpose.
