* netns: embed ip6_dst_ops directlyAlexey Dobriyan2009-09-014-44/+44
| | | | | | | | | | | | | | | | | struct net::ipv6.ip6_dst_ops is separatedly dynamically allocated, but there is no fundamental reason for it. Embed it directly into struct netns_ipv6. For that: * move struct dst_ops into separate header to fix circular dependencies I honestly tried not to, it's pretty impossible to do other way * drop dynamical allocation, allocate together with netns For a change, remove struct dst_ops::dst_net, it's deducible by using container_of() given dst_ops pointer.

* ixgbe: Patch to fix 82599 multispeed fiber link issues when driver is loaded ↵Mallikarjuna R Chilakala2009-09-011-11/+11
| | | | | | | | | | | | | | | | | | | without any cable and reconnecting it to 1G partner In 82599 multi speed fiber case when driver is loaded without any cable and reconnecting the cable with a 1G partner does not bring up the link in 1Gb mode. When there is no link we first setup the link at 10G & 1G and then try to re-establish the link at highest speed 10G and thereby changing autoneg_advertised value to highest speed 10G. After connecting back the cable to a 1G link partner we never try 1G as autoneg advertised value is changed to link at 10G only. The following patch fixes the issue by properly initializing the autoneg_advertised value just before exiting from link setup routine.

* ixgbe: Properly disable DCB arbiters prior to applying changesPeter P Waskiewicz Jr2009-09-011-7/+14
| | | | | | | | | | | | When disabling the Rx and Tx data arbiters prior to configuration changes, the arbiters were not being shut down properly. This can create a race in the DCB hardware blocks, and potentially hang the arbiters. Also, the Tx descriptor arbiter shouldn't be disabled when applying configuration changes; disabling this arbiter can cause a Tx hang.

* e1000: Fix for e1000 kills IPMI on a tagged vlan.Graham, David2009-09-011-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enabling VLAN filters (VFE) when the primary interface is brought up (per commit 78ed11a) has caused problems for some users who manage their systems using IPMI over a VLAN. This is because when the driver enables the VLAN filter, this same filter table is enabled for the management channel, and the table is initially empty, which means that the IPMI/VLAN packets are filtered out and not received by the BMC. This is a problem only on e1000 class adapters, as it is only on e1000 that the filter table is common to the management and host streams. With this change, filtering is only enabled when one or more host VLANs exist, and is disabled when the last host VLAN is removed. VLAN filtering is always disabled when the primary interface is in promiscuous mode, and will be (re)enabled if VLANs exist when the interface exits promiscuous mode. Note that this does not completely resolve the issue for those using VLAN management, because if the host adds a VLAN, then the above problem occurs when that VLAN is enabled. However, it does mean the there is no problem for configurations where management is on a VLAN and the host is not. A complete solution to this issue would require further driver changes. The driver would need to discover if (and which) management VLANs are active before enabling VLAN filtering, so that it could ensure that the managed VLANs are included in the VLAN filter table. This discovery requires that the BMC identifies its VLAN in registers accessible to the driver, and at least on Dell PE2850 systems the BMC does not identify its VLAN to allow such discovery. Intel is pursuing this issue with the BMC vendor.

* Revert Backoff [v3]: Calculate TCP's connection close threshold as a time value.Damian Lukowski2009-09-012-4/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RFC 1122 specifies two threshold values R1 and R2 for connection timeouts, which may represent a number of allowed retransmissions or a timeout value. Currently linux uses sysctl_tcp_retries{1,2} to specify the thresholds in number of allowed retransmissions. For any desired threshold R2 (by means of time) one can specify tcp_retries2 (by means of number of retransmissions) such that TCP will not time out earlier than R2. This is the case, because the RTO schedule follows a fixed pattern, namely exponential backoff. However, the RTO behaviour is not predictable any more if RTO backoffs can be reverted, as it is the case in the draft "Make TCP more Robust to Long Connectivity Disruptions" (http://tools.ietf.org/html/draft-zimmermann-tcp-lcd). In the worst case TCP would time out a connection after 3.2 seconds, if the initial RTO equaled MIN_RTO and each backoff has been reverted. This patch introduces a function retransmits_timed_out(N), which calculates the timeout of a TCP connection, assuming an initial RTO of MIN_RTO and N unsuccessful, exponentially backed-off retransmissions. Whenever timeout decisions are made by comparing the retransmission counter to some value N, this function can be used, instead. The meaning of tcp_retries2 will be changed, as many more RTO retransmissions can occur than the value indicates. However, it yields a timeout which is similar to the one of an unpatched, exponentially backing off TCP in the same scenario. As no application could rely on an RTO greater than MIN_RTO, there should be no risk of a regression.

* Revert Backoff [v3]: Revert RTO on ICMP destination unreachableDamian Lukowski2009-09-014-4/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | Here, an ICMP host/network unreachable message, whose payload fits to TCP's SND.UNA, is taken as an indication that the RTO retransmission has not been lost due to congestion, but because of a route failure somewhere along the path. With true congestion, a router won't trigger such a message and the patched TCP will operate as standard TCP. This patch reverts one RTO backoff, if an ICMP host/network unreachable message, whose payload fits to TCP's SND.UNA, arrives. Based on the new RTO, the retransmission timer is reset to reflect the remaining time, or - if the revert clocked out the timer - a retransmission is sent out immediately. Backoffs are only reverted, if TCP is in RTO loss recovery, i.e. if there have been retransmissions and reversible backoffs, already. Changes from v2: 1) Renaming of skb in tcp_v4_err() moved to another patch. 2) Reintroduced tcp_bound_rto() and __tcp_set_rto(). 3) Fixed code comments.

* dcbnl: Add support for setapp/getapp commands to dcbnlYi Zou2009-09-011-0/+18
| | | | | | | | | | | | | | | | | | | | | | | This patch adds dcbnl command definitions to support setapp/getapp functionality from the IEEE 802.1Qaz Data Center Bridging Capability Exchange protocol (DCBX) specification. Section 3.3 defines the application protocol and its 802.1p user priority in DCBX, which is implemented here as a pair of setapp/getapp commands in the kernel dcbnl for setting and retrieving the user priority for an given application protocol. The protocol is identified by the combination of an id and an idtype. Currently, when idtype is 0, the corresponding id gives the ether type of this protocol, e.g., for FCoE, it will be 0x8906; when idtype is 1, then the corresponding id gives the TCP or UDP port number. For more information regarding DCBX spec., please refer to the following: http://www.ieee802.org/1/files/public/docs2008/ az-wadekar-dcbx-capability-exchange-discovery-protocol-1108-v1.01.pdf Signed-off-by: Yi Zou <yi.zou@intel.com> Acked-by: Peter P Waskiewicz Jr <peter.p.waskiewicz.jr@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: David S.

This is expected to be called by the kernel FCoE stack upon receiving a request for creating an FCoE instance on the corresponding netdev interface. When implemented by the actual HW, the HW driver check the op code to perform corresponding initialization or clean up for FCoE. The initialization normally includes allocating extra queues for FCoE, setting corresponding HW registers for FCoE, indicating FCoE offload features via netdev, etc. The clean-up would include releasing the resources allocated for FCoE.

* pkt_sched: Fix resource limiting in pfifo_fastKrishna Kumar2009-08-301-4/+4
| | | | | | | | | | | | | | | | | | pfifo_fast_enqueue has this check: if (skb_queue_len(list) < qdisc_dev(qdisc)->tx_queue_len) { which allows each band to enqueue upto tx_queue_len skbs for a total of 3*tx_queue_len skbs. I am not sure if this was the intention of limiting in qdisc. Patch compiled and 32 simultaneous netperf testing ran fine. Also: # tc -s qdisc show dev eth2 qdisc pfifo_fast 0: root bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1 Sent 16835026752 bytes 373116 pkt (dropped 0, overlimits 0 requeues 25) rate 0bit 0pps backlog 0b 0p requeues 25 Signed-off-by: Krishna Kumar <krkumar2@in.ibm.com> Signed-off-by: David S.
