2018-04-19net: pskb_trim_rcsum() and CHECKSUM_COMPLETE are friendsEric Dumazet2-3/+16
After working on IP defragmentation lately, I found that some large packets defeat CHECKSUM_COMPLETE optimization because of NIC adding zero paddings on the last (small) fragment. While removing the padding with pskb_trim_rcsum(), we set skb->ip_summed to CHECKSUM_NONE, forcing a full csum validation, even if all prior fragments had CHECKSUM_COMPLETE set. We can instead compute the checksum of the part we are trimming, usually smaller than the part we keep. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

2018-04-19tcp: track total bytes delivered with ECN CE marksYuchung Cheng3-0/+4
Introduce a new delivered_ce stat in tcp socket to estimate number of packets being marked with CE bits. The estimation is done via ACKs with ECE bit. Depending on the actual receiver behavior, the estimation could have biases. Since the TCP sender can't really see the CE bit in the data path, so the sender is technically counting packets marked delivered with the "ECE / ECN-Echo" flag set. With RFC3168 ECN, because the ECE bit is sticky, this count can drastically overestimate the nummber of CE-marked data packets With DCTCP-style ECN this should be reasonably precise unless there is loss in the ACK path, in which case it's not precise. With AccECN proposal this can be made still more precise, even in the case some degree of ACK loss. However this is sender's best estimate of CE information.

2018-04-19tcp: better delivery accounting for SYN-ACK and SYN-dataYuchung Cheng1-3/+7
the tcp_sock:delivered has inconsistent accounting for SYN and FIN. 1. it counts pure FIN 2. it counts pure SYN 3. it counts SYN-data twice 4. it does not count SYN-ACK For congestion control perspective it does not matter much as C.C. only cares about the difference not the aboslute value. But the next patch would export this field to user-space so it's better to report the absolute value w/o these caveats. This patch counts SYN, SYN-ACK, or SYN-data delivery once always in the "delivered" field.

2018-04-18ipv6: frags: fix a lockdep false positiveEric Dumazet1-11/+12
lockdep does not know that the locks used by IPv4 defrag and IPv6 reassembly units are of different classes. It complains because of following chains : 1) sch_direct_xmit() (lock txq->_xmit_lock) dev_hard_start_xmit() xmit_one() dev_queue_xmit_nit() packet_rcv_fanout() ip_check_defrag() ip_defrag() spin_lock() (lock frag queue spinlock) 2) ip6_input_finish() ipv6_frag_rcv() (lock frag queue spinlock) ip6_frag_queue() icmpv6_param_prob() (lock txq->_xmit_lock at some point) We could add lockdep annotations, but we also can make sure IPv6 calls icmpv6_param_prob() only after the release of the frag queue spinlock, since this naturally makes frag queue spinlock a leaf in lock hierarchy.

2018-04-18hv_netvsc: propogate Hyper-V friendly name into interface aliasStephen Hemminger2-0/+29
This patch implement the 'Device Naming' feature of the Hyper-V network device API. In Hyper-V on the host through the GUI or PowerShell it is possible to enable the device naming feature which causes the host to make available to the guest the name of the device. This shows up in the RNDIS protocol as the friendly name. The name has no particular meaning and is limited to 256 characters. The value can only be set via PowerShell on the host, but could be scripted for mass deployments. The default value is the string 'Network Adapter' and since that is the same for all devices and useless, the driver ignores it. In Windows, the value goes into a registry key for use in SNMP ifAlias. For Linux, this patch puts the value in the network device alias property; where it is visible in ip tools and SNMP. The host provided ifAlias is just a suggestion, and can be overridden by later ip commands. Also requires exporting dev_set_alias in netdev core.

IPv6 FIB will only contain FIB entries with exception routes added to the FIB entry. Once this transformation is complete, FIB lookups will return a fib6_info with the lookup functions still returning a dst based rt6_info. The current code uses rt6_info for both paths and overloads the rt6_info variable usually called 'rt'. This patch introduces a new 'f6i' variable name for the result of the FIB lookup and keeps 'rt' as the dst based return variable. 'f6i' becomes a fib6_info in a later patch which is why it is introduced as f6i now; avoids the additional churn in the later patch. In addition, remove RTF_CACHE and dst checks from fib6 add and delete since they can not happen now and will never happen after the data type flip.

2018-04-17net/ipv6: Add rt6_info create function for ip6_pol_route_lookupDavid Ahern1-4/+25
ip6_pol_route_lookup is the lookup function for ip6_route_lookup and rt6_lookup. At the moment it returns either a reference to a FIB entry or a cached exception. To move FIB entries to a separate struct, this lookup function needs to convert FIB entries to an rt6_info that is returned to the caller.
