Description
Description
In the Linux kernel, the following vulnerability has been resolved:
smb: server: make use of smbdirect_socket.send_io.bcredits
It turns out that our code will corrupt the stream of
reassabled data transfer messages when we trigger an
immendiate (empty) send.
In order to fix this we'll have a single 'batch' credit per
connection. And code getting that credit is free to use
as much messages until remaining_length reaches 0, then
the batch credit it given back and the next logical send can
happen.
