SendRRorRNR needs to acknowledge received I-frames (actually every packet needs to acknowledge received I-frames by sending the proper packet sequence number), so ReqSeq is set to the next I-frame number sequence to be pulled by the reassembly function. SendRRorRNR tells the remote side about local busy conditions, it sends a Receiver Ready frame if local busy is false or a Receiver Not Ready if local busy is true. ReqSeq is the packet's field to send the number of the acknowledged packets. Signed-off-by: NGustavo F. Padovan <gustavo@las.ic.unicamp.br> Signed-off-by: NMarcel Holtmann <marcel@holtmann.org>

RejActioned is used to prevent retransmission when a entity is on the WAIT_F state, i.e., waiting for a frame with F-bit set due local busy condition or a expired retransmission timer. (When these two events raise they send a frame with the Poll bit set and enters in the WAIT_F state to wait for a frame with the Final bit set.) The local entity doesn't send I-frames(the data frames) until the receipt of a frame with F-bit set. When that happens it also set RejActioned to false. RejActioned is a mandatory feature of ERTM spec. Signed-off-by: NGustavo F. Padovan <gustavo@las.ic.unicamp.br> Signed-off-by: NMarcel Holtmann <marcel@holtmann.org>

As specified by ERTM spec an ERTM channel can acknowledge received I-frames(the data frames) by sending an I-frame with the proper ReqSeq value (i.e. ReqSeq is set to BufferSeq). Until now we aren't setting the ReqSeq value on I-frame control bits. That way we can save sending S-frames(Supervise frames) only to acknowledge receipt of I-frames. It is very helpful to the full-duplex channel. ReqSeq is the packet sequence number sent in an acknowledgement frame to acknowledge receipt of frames up to (ReqSeq - 1). BufferSeq controls the receiver buffer, it is used to delay acknowledgement of new frames to not cause buffer overflow. BufferSeq value is not increased until frames are pulled by reassembly function. Signed-off-by: NGustavo F. Padovan <gustavo@las.ic.unicamp.br> Signed-off-by: NMarcel Holtmann <marcel@holtmann.org>

SrejActioned is a flag that when set prevents local side to retransmit a I-frame(the data frame) already retransmitted. The local entity can retransmit again only when it receives a SREJ frame with the F-bit set. SREJ frame - Selective Reject frame - is sent when an entity wants the retransmission of a specific I-frame that was lost or corrupted. This bug can put ERTM in an unknown state once the entity can't retransmit. A frame with the Final bit set is expected when the local side sends a frame with the Poll bit set due to a local busy condition or a retransmission timer expired. (Receipt of P-bit shall always be replied by a frame with the F-bit set). pi->conn_state keeps informations about many ERTM flags including SrejActioned. Signed-off-by: NGustavo F.

Fix ERTM's full-duplex channel to work as specified by ERTM spec. ERTM needs to handle state vars, timers and counters to send and receive I-frames(the data frames), i.e., for both sides of data communication. We initialize all of them to the default values here.

Fix dma-api-checking warnings in Sun HME Sun HME driver is mapping the first fragment with dma_map_single and subsequent fragments with dma_map_page.

Take advantage of the fact that an explicit rtnl_kill_links is unnecessary (and skipping it improves batching), as network namespace exit calls dellink on all remaining virtual devices, and rtnl_link_unregister calls dellink on all outstanding devices in that network namespace. To do this we need to leave the vlan proc directories in place until after network device exit time, which is done by using register_pernet_subsys instead of register_pernet_device.

Data structures are carefully composed to require minimal additions. For example, the struct tcp_options_received cookie_plus variable fits between existing 16-bit and 8-bit variables, requiring no additional space (taking alignment into consideration). There are no additions to tcp_request_sock, and only 1 pointer in tcp_sock. This is a significantly revised implementation of an earlier (year-old) patch that no longer applies cleanly, with permission of the original author (Adam Langley): http://thread.gmane.org/gmane.linux.network/102586 The principle difference is using a TCP option to carry the cookie nonce, instead of a user configured offset in the data. This is more flexible and less subject to user configuration error. Such a cookie option has been suggested for many years, and is also useful without SYN data, allowing several related concepts to use the same extension option.
