* tcp: improve latencies of timer triggered eventsEric Dumazet2012-07-204-51/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modern TCP stack highly depends on tcp_write_timer() having a small latency, but current implementation doesn't exactly meet the expectations. When a timer fires but finds the socket is owned by the user, it rearms itself for an additional delay hoping next run will be more successful. tcp_write_timer() for example uses a 50ms delay for next try, and it defeats many attempts to get predictable TCP behavior in term of latencies. Use the recently introduced tcp_release_cb(), so that the user owning the socket will call various handlers right before socket release. This will permit us to post a followup patch to address the tcp_tso_should_defer() syndrome (some deferred packets have to wait RTO timer to be transmitted, while cwnd should allow us to send them sooner) Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: Tom Herbert <therbert@google.com> Cc: Yuchung Cheng <ycheng@google.com> Cc: Neal Cardwell <ncardwell@google.com> Cc: Nandita Dukkipati <nanditad@google.com> Cc: H.K.

| | | | | | | | | | | | | | | | | | | | | When/if sysctl_tcp_abc > 1, we expect to increase cwnd by 2 if the received ACK acknowledges more than 2*MSS bytes, in tcp_slow_start() Problem is this RFC 3465 statement is not correctly coded, as the while () loop increases snd_cwnd one by one.

| | | | | | | | | | | | | | | | | | | | | | | | | | The Janz VMOD-ICAN3 hardware has support for one shot packet transmission. This means that a packet will be attempted to be sent once, with no automatic retries. The SocketCAN core has a controller-wide setting for this mode: CAN_CTRLMODE_ONE_SHOT. The Janz VMOD-ICAN3 hardware supports this flag on a per-packet level, but the SocketCAN core does not. Signed-off-by: Ira W.

| * can: janz-ican3: avoid firmware lockup caused by infinite bus error quotaIra W. Snyder2012-07-201-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the bus error quota is set to infinite and the host CPU cannot keep up, the Janz VMOD-ICAN3 firmware will stop responding to control messages until the controller is reset. The firmware will automatically stop sending bus error messages when the quota is reached, and will only resume sending bus error messages when the quota is re-set to a positive value. This limitation is worked around by setting the bus error quota to one message, and then re-setting the quota to one message every time a bus error message is received. By doing this, the firmware never stops responding to control messages. The CAN bus can be reset without a hard-reset of the controller card. Signed-off-by: Ira W.

| * can: janz-ican3: fix support for CAN_RAW_RECV_OWN_MSGSIra W. Snyder2012-07-201-46/+157
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Janz VMOD-ICAN3 firmware does not support any sort of TX-done notification or interrupt. The driver previously used the hardware loopback to attempt to work around this deficiency, but this caused all sockets to receive all messages, even if CAN_RAW_RECV_OWN_MSGS is off. Using the new function ican3_cmp_echo_skb(), we can drop the loopback messages and return the original skbs. This fixes the issues with CAN_RAW_RECV_OWN_MSGS. A private skb queue is used to store the echo skbs. This avoids the need for any index management. Due to a lack of TX-error interrupts, bus errors are permanently enabled, and are used as a TX-error notification. This is used to drop an echo skb when transmission fails. Bus error packets are not generated if the user has not enabled bus error reporting. Signed-off-by: Ira W. Snyder <iws@ovro.caltech.edu> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The error and byte counter statistics were being incremented incorrectly. For example, a TX error would be counted both in tx_errors and rx_errors. This corrects the problem so that tx_errors and rx_errors are only incremented for errors caused by packets sent to the bus. Error packets generated by the driver are not counted. The byte counters are only increased for packets which are actually transmitted or received from the bus. Error packets generated by the driver are not counted. Signed-off-by: Ira W. Snyder <iws@ovro.caltech.edu> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>

| * can: flexcan: add 2nd clock to support imx53 and newerSteffen Trumtrar2012-07-201-18/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for a second clock to the flexcan driver. On modern freescale ARM cores like the imx53 and imx6q two clocks ("ipg" and "per") must be enabled in order to access the CAN core. In the original driver, the clock was requested without specifying the connection id, further all mainline ARM archs with flexcan support (imx28, imx25, imx35) register their flexcan clock without a connection id, too. This patch first renames the existing clk variable to clk_ipg and converts it to devm for easier error handling. The connection id "ipg" is added to the devm_clk_get() call. Then a second clock "per" is requested. As all archs don't specify a connection id, both clk_get return the same clock. This ensures compatibility to existing flexcan support and adds support for imx53 at the same time. After this patch hits mainline, the archs may give their existing flexcan clock the "ipg" connection id and implement a dummy "per" clock. This patch has been tested on imx28 (unmodified clk tree) and on imx53 with a seperate "ipg" and "per" clock.

The L2CAP ERTM transmit window size determines the maximum number of unacked frames that may be outstanding at any time. It is configured separately for each direction of an ERTM connection. Each side sends a configuration request with a tx_win field indicating how many unacked frames it is capable of receiving before sending an ack. The configuration response's tx_win field shows how many frames the transmitter will actually send before waiting for an ack. It's important to trace both the actual transmit window (to check for validity of incoming frames) and the number of frames that the transmitter will send before waiting (to send acks at the appropriate time). Now there are separate tx_win and ack_win values. ack_win is updated based on configuration responses, and is used to determine when acks are sent.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To help debugging printed hex object use standard bluetooth specifiers in hci_event. The patch changes format from 0x%04x to 0x%4.4x; print manufacturer id and handle in hex instead of int; print opcode always in 0x%4.4x format; status in 0x%2.2x.
