skb_flow_dissect() dissects only transport header type in ip_proto. It dose not give any information about IPv4 or IPv6. This patch adds new member, n_proto, to struct flow_keys. Which records the IP layer type. i.e IPv4 or IPv6. This can be used in netdev->ndo_rx_flow_steer driver function to dissect flow. Adding new member to flow_keys increases the struct size by around 4 bytes. This causes BUILD_BUG_ON(sizeof(qcb->data) < sz); to fail in qdisc_cb_private_validate() So increase data size by 4 Signed-off-by: Govindarajulu Varadarajan <_govind@gmx.com> Signed-off-by: David S.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-06-20 This series contains updates to i40e and i40evf. Anjali provides an update to the registers to handle the updates from the hardware. Also provides a fix so that we do not try to access the rings through the qvectors at the time of freeing the qvectors. Jesse provides a workaround for some older NVM versions where the NVM was not filling in the GLQF_HKEY register, so made sure that the critical register is initialized. Michal provides a fix to reset the head and tail on admin queue initialization where head and tail are not reset by the hardware. Neerav adds a helper routine that would wait for the Rx/Tx queue to reach the enable or disable state that is requested. Also provides a fix to the debugfs command "lldp get remote" which was dumping the local LLDPDU instead of the peer's LLDPDU. Fixed a bug when all the Tx hang recovery mechanisms have failed and the driver tries to bring down the interface in the interrupt context. Shannon provides a patch to clear the Virtual Ethernet Bridge (VEB) stats when the PF stats are cleared. Also cleans the service tasks so that they do not run while a reset is in progress. Mitch fixes an issue in i40evf_get_rxfh() where only fifteen registers were being read instead of all sixteen. Carolyn provides a change to the RSS configuration to set table size and write to the hardware to confirm the RSS table size being used. Kamil makes a change to the admin queue debug prints so that they will not cause segmentation faults in some of our tool applications. ==================== Signed-off-by: David S.

Commit 3fd091e7 ("[SCTP]: Remove multiple levels of msecs to jiffies conversions.") has silently changed permissions for rto_alpha and rto_beta knobs from 0644 to 0444. The purpose of this was to discourage users from tweaking rto_alpha and rto_beta knobs in production environments since they are key to correctly compute rtt/srtt. RFC4960 under section 6.3.1. RTO Calculation says regarding rto_alpha and rto_beta under rule C3 and C4: [...] C3) When a new RTT measurement R' is made, set RTTVAR <- (1 - RTO.Beta) * RTTVAR + RTO.Beta * |SRTT - R'| and SRTT <- (1 - RTO.Alpha) * SRTT + RTO.Alpha * R' Note: The value of SRTT used in the update to RTTVAR is its value before updating SRTT itself using the second assignment. After the computation, update RTO <- SRTT + 4 * RTTVAR. C4) When data is in flight and when allowed by rule C5 below, a new RTT measurement MUST be made each round trip. Furthermore, new RTT measurements SHOULD be made no more than once per round trip for a given destination transport address. There are two reasons for this recommendation: First, it appears that measuring more frequently often does not in practice yield any significant benefit [ALLMAN99]; second, if measurements are made more often, then the values of RTO.Alpha and RTO.Beta in rule C3 above should be adjusted so that SRTT and RTTVAR still adjust to changes at roughly the same rate (in terms of how many round trips it takes them to reflect new values) as they would if making only one measurement per round-trip and using RTO.Alpha and RTO.Beta as given in rule C3. However, the exact nature of these adjustments remains a research issue. [...] While it is discouraged to adjust rto_alpha and rto_beta and not further specified how to adjust them, the RFC also doesn't explicitly forbid it, but rather gives a RECOMMENDED default value (rto_alpha=3, rto_beta=2). We have a couple of users relying on the old permissions before they got changed. That said, if someone really has the urge to adjust them, we could allow it with a warning in the log. Fixes: 3fd091e7 ("[SCTP]: Remove multiple levels of msecs to jiffies conversions.")
