* dccp: Allow to distinguish original and retransmitted packetsGerrit Renker2008-07-26
| | | | | | | | | | | | | | | | | | | | | | | | | This patch allows the sender to distinguish original and retransmitted packets, which is in particular needed for the retransmission of DCCP-Requests: * the first Request uses ISS (generated in net/dccp/ip*.c), and sets GSS = ISS; * all retransmitted Requests use GSS' = GSS + 1, so that the n-th retransmitted Request has sequence number ISS + n (mod 48). To add generic support, the patch reorganises existing code so that: * icsk_retransmits == 0 for the original packet and * icsk_retransmits = n > 0 for the n-th retransmitted packet at the time dccp_transmit_skb() is called, via dccp_retransmit_skb(). Thanks to Wei Yongjun for pointing this problem out. Further changes: ---------------- * removed the `skb' argument from dccp_retransmit_skb(), since sk_send_head is used for all retransmissions (the exception is client-Acks in PARTOPEN state, but these do not use sk_send_head); * since sk_send_head always contains the original skb (via dccp_entail()), skb_cloned() never evaluated to true and thus pskb_copy() was never used.

* Revert "pkt_sched: sch_sfq: dump a real number of flows"David S. Miller2008-07-26
| | | | | | | | | | | This reverts commit f867e6af94239a04ec23aeec2fcda5aa58e41db7. Based upon discussions between Jarek and Patrick McHardy this is field being set is more a config parameter than a statistic. And we should add a true statistic to provide this information if we really want it. Signed-off-by: David S. Miller <davem@davemloft.net>

* net: convert BUG_TRAP to generic WARN_ONIlpo Järvinen2008-07-26
| | | | | | | | | | | | | | Removes legacy reinvent-the-wheel type thing. The generic machinery integrates much better to automated debugging aids such as kerneloops.org (and others), and is unambiguous due to better naming. Non-intuively BUG_TRAP() is actually equal to WARN_ON() rather than BUG_ON() though some might actually be promoted to BUG_ON() but I left that to future. I could make at least one BUILD_BUG_ON conversion. Signed-off-by: Ilpo Järvinen <ilpo.jarvinen@helsinki.fi> Signed-off-by: David S. Miller <davem@davemloft.net>

* tcp: Clear probes_out more aggressively in tcp_ack().David S. Miller2008-07-23

Otherwise if we get a sequence of ACKs while we do have packets outstanding over and over again, we'll never clear the probes_out value and eventually think the connection is too sick and we'll reset it. This appears to be some "optimization" added to tcp_ack() in the 2.4.x timeframe. In 2.2.x, probes_out is pretty much always cleared by tcp_ack(). Here is Eric's original report: ---------------------------------------- Apparently, we can in some situations reset TCP connections in a couple of seconds when some frames are lost.

| | * r6040: rework init_one error handlingFlorian Fainelli2008-07-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch reworks the error handling in r6040_init_one in order not to leak resources and correcly unmap and release PCI regions of the MAC. Also prefix printk's with the driver name for clarity. Signed-off-by: Florian Fainelli <florian.fainelli@telecomint.eu> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch bumps the release of the r6040 driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the default waiting time of a packet, which along with our previous r6040_rx path, was causing huge delays with another host (160 to 230 ms).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch completely reworks the RX path in order to be more accurate about what is going on with the MAC. We no longer read the error from the MLSR register instead read the descriptor status register which reflects, the error per descriptor. We now allocate skbs on the fly in r6040_rx, and we handle allocation failure instead of simply dropping the packet. Remove the rx_free_desc counter of r6040_private structure since we allocate skbs in the RX path. r6040_rx_buf_alloc is now removed and becomes unuseless.

| | * sfc: Create one RX queue and interrupt per CPU package by defaultBen Hutchings2008-07-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using multiple cores in the same package to handle received traffic does not appear to provide a performance benefit. Therefore use CPU topology information to count CPU packages and use that as the default number of RX queues and interrupts. We rely on interrupt balancing to spread the interrupts across packages.
