Current code does not lock anything when calculating the TX and RX stats. As a result, the RX and TX data reported by ifconfig are not accuracy in a system with high network throughput and multiple CPUs (in my test, RX/TX = 83% between 2 HyperV VM nodes which have 8 vCPUs and 40G Ethernet). This patch fixed the above issue by using per_cpu stats. netvsc_get_stats64() summarizes TX and RX data by iterating over all CPUs to get their respective stats. This v2 patch addressed David's comments on the cleanup path when netdev_alloc_pcpu_stats() failed. Signed-off-by:

commit d2788d34 ("net: sched: further simplify handle_ing") removed the call to qdisc_enqueue_root(). However, after this removal we no longer set qdisc pkt length. This breaks traffic policing on ingress. This is the minimum fix: set qdisc pkt length before tc_classify. Only setting the length does remove support for 'stab' on ingress, but as Alexei pointed out: "Though it was allowed to add qdisc_size_table to ingress, it's useless. Nothing takes advantage of recomputed qdisc_pkt_len". Jamal suggested to use qdisc_pkt_len_init(), but as Eric mentioned that would result in qdisc_pkt_len_init to no longer get inlined due to the additional 2nd call site. ingress policing is rare and GRO doesn't really work that well with police on ingress, as we see packets > mtu and drop skbs that -- without aggregation -- would still have fitted the policier budget. Thus to have reliable/smooth ingress policing GRO has to be turned off.

Now we allow storing more request socks per listener, we might hit syncookie mode less often and hit following bug in our stack : When we send a burst of syncookies, then exit this mode, tcp_synq_no_recent_overflow() can return false if the ACK packets coming from clients are coming three seconds after the end of syncookie episode. This is a way too strong requirement and conflicts with rest of syncookie code which allows ACK to be aged up to 2 minutes. Perfectly valid ACK packets are dropped just because clients might be in a crowded wifi environment or on another planet. So let's fix this, and also change tcp_synq_overflow() to not dirty a cache line for every syncookie we send, as we are under attack. Signed-off-by:

The rx_dropped stat wasn't being reported when ip_tunnel_get_stats64 was called. This was leading to some confusing results in my debug as I was seeing rx_errors increment but no other value which pointed me toward the type of error being seen. This change corrects that by using netdev_stats_to_stats64 to copy all available dev stats instead of just the few that were hand picked. Signed-off-by:

Jon Paul Maloy authored
Currently, the packet sequence number is updated and added to each packet at the moment a packet is added to the link backlog queue. This is wasteful, since it forces the code to traverse the send packet list packet by packet when adding them to the backlog queue. It would be better to just splice the whole packet list into the backlog queue when that is the right action to do. In this commit, we do this change. Also, since the sequence numbers cannot now be assigned to the packets at the moment they are added the backlog queue, we do instead calculate and add them at the moment of transmission, when the backlog queue has to be traversed anyway. We do this in the function tipc_link_push_packet(). Reviewed-by:

The link congestion algorithm used until now implies two problems. - It is too generous towards lower-level messages in situations of high load by giving "absolute" bandwidth guarantees to the different priority levels. LOW traffic is guaranteed 10%, MEDIUM is guaranted 20%, HIGH is guaranteed 30%, and CRITICAL is guaranteed 40% of the available bandwidth. But, in the absence of higher level traffic, the ratio between two distinct levels becomes unreasonable. E.g. if there is only LOW and MEDIUM traffic on a system, the former is guaranteed 1/3 of the bandwidth, and the latter 2/3. This again means that if there is e.g. one LOW user and 10 MEDIUM users, the former will have 33.3% of the bandwidth, and the others will have to compete for the remainder, i.e. each will end up with 6.7% of the capacity. - Packets of type MSG_BUNDLER are created at SYSTEM importance level, but only after the packets bundled into it have passed the congestion test for their own respective levels. Since bundled packets don't result in incrementing the level counter for their own importance, only occasionally for the SYSTEM level counter, they do in practice obtain SYSTEM level importance. Hence, the current implementation provides a gap in the congestion algorithm that in the worst case may lead to a link reset. We now refine the congestion algorithm as follows: - A message is accepted to the link backlog only if its own level counter, and all superior level counters, permit it. - The importance of a created bundle packet is set according to its contents. A bundle packet created from messges at levels LOW to CRITICAL is given importance level CRITICAL, while a bundle created from a SYSTEM level message is given importance SYSTEM. In the latter case only subsequent SYSTEM level messages are allowed to be bundled into it. This solves the first problem described above, by making the bandwidth guarantee relative to the total number of users at all levels; only the upper limit for each level remains absolute. In the example described above, the single LOW user would use 1/11th of the bandwidth, the same as each of the ten MEDIUM users, but he still has the same guarantee against starvation as the latter ones. The fix also solves the second problem. If the CRITICAL level is filled up by bundle packets of that level, no lower level packets will be accepted any more. Suggested-by:

We change the sequence number checkpointing that is performed by the timer in order to discover if the peer is active. Currently, we store a checkpoint of the next expected sequence number "rcv_nxt" at each timer expiration, and compare it to the current expected number at next timeout expiration. Instead, we now use the already existing field "silent_intv_cnt" for this task. We step the counter at each timeout expiration, and zero it at each valid received packet. If no valid packet has been received from the peer after "abort_limit" number of silent timer intervals, the link is declared faulty and reset. We also remove the multiple instances of timer activation from inside the FSM function "link_state_event()", and now do it at only one place; at the end of the timer function itself. Reviewed-by:

Although the sequence number in the TIPC protocol is 16 bits, we have until now stored it internally as an unsigned 32 bits integer. We got around this by always doing explicit modulo-65535 operations whenever we need to access a sequence number. We now make the incoming and outgoing sequence numbers to unsigned 16-bit integers, and remove the modulo operations where applicable. We also move the arithmetic inline functions for 16 bit integers to core.h, and the function buf_seqno() to msg.h, so they can easily be accessed from anywhere in the code. Reviewed-by:

When we try to add new inline functions in the code, we sometimes run into circular include dependencies. The main problem is that the file core.h, which really should be at the root of the dependency chain, instead is a leaf. I.e., core.h includes a number of header files that themselves should be allowed to include core.h. In reality this is unnecessary, because core.h does not need to know the full signature of any of the structs it refers to, only their type declaration. In this commit, we remove all dependencies from core.h towards any other tipc header file. As a consequence of this change, we can now move the function tipc_own_addr(net) from addr.c to addr.h, and make it inline. There are no functional changes in this commit. Reviewed-by:

Prior to this commit, the link timer has been running at a "continuity interval" of configured link tolerance/4. When a timer wakes up and discovers that there has been no sign of life from the peer during the previous interval, it divides its own timer interval by another factor four, and starts sending one probe per new interval. When the configured link tolerance time has passed without answer, i.e. after 16 unacked probes, the link is declared faulty and reset. This is unnecessary complex. It is sufficient to continue with the original continuity interval, and instead reset the link after four missed probe responses. This makes the timer handling in the link simpler, and opens up for some planned later changes in this area. This commit implements this change. Reviewed-by:

OS2BMC feature will allow the server to communicate with the on-board BMC/idrac (Baseboard Management Controller) over the LOM via standard Ethernet. When OS2BMC feature is enabled, the LOM will filter traffic coming from the host. If the destination MAC address matches the iDRAC MAC address, it will forward the packet to the NC-SI side band interface for iDRAC processing. Otherwise, it would send it out on the wire to the external network. Broadcast and multicast packets are sent on the side-band NC-SI channel and on the wire as well. Some of the packet filters are not supported in the NIC and hence driver will identify such packets and will hint the NIC to send those packets to the BMC. This is done by duplicating packets on the management ring. Packets are sent to the management ring, by setting mgmt bit in the wrb header. The NIC will forward the packets on the management ring to the BMC through the side-band NC-SI channel.

Pablo Neira Ayuso says: ==================== Netfilter ingress support (v4) This is the v4 round of patches to add the Netfilter ingress hook, it basically comes in two steps: 1) Add the CONFIG_NET_INGRESS switch to wrap the ingress static key around it. The idea is to use the same global static key to avoid adding more code to the hot path. 2) Add the Netfilter ingress hook after the tc ingress hook, under the global ingress_needed static key. As I said, the netfilter ingress hook also has its own static key, that is nested under the global static key. Please, see patch 5/5 for performance numbers and more information. I originally started this next round, as it was suggested, exploring the independent static key for netfilter ingress just after tc ingress, but the results that I gathered from that patch are not good for non-users: Result: OK: 6425927(c6425843+d83) usec, 100000000 (60byte,0frags) 15561955pps 7469Mb/sec (7469738400bps) errors: 100000000 this roughly means 500Kpps less performance wrt. the base numbers, so that's the reason why I discarded that approach and I focused on this. The idea of this patchset is to open the window to nf_tables, which comes with features that will work out-of-the-box (once the boiler plate code to support the 'netdev' table family is in place), to avoid repeating myself [1], the most relevant features are: 1) Multi-dimensional key dictionary lookups. 2) Arbitrary stateful flow tables. 3) Transactions and good support for dynamic updates. But there are also interest aspects to consider from userspace, such as the ability to support new layer 2 protocols without kernel updates, a well-defined netlink interface, userspace libraries and utilities for third party applications, among others. I hope we can be happy with this approach. Please, apply. Thanks. [1] http://marc.info/?l=netfilter-devel&m=143033337020328&w=2 ==================== Signed-off-by:

I can see gcc gets the code under the ingress static key out of the hot path. Then, on that cold branch, it generates the code to accomodate the netfilter ingress static key. My explanation for this is that this reduces the pressure on the instruction cache for non-users as the new code is out of the hot path, and it comes with minimal impact for tc ingress users.
