2017-12-03hv_netvsc: optimize initialization of RNDIS headerStephen Hemminger1-31/+26
The memset of the whole maximum possible RNDIS header is unnecessary. For the main part of the header use a structure assignment. No need to memset the whole per packet info. Instead rely on caller to set what it wants. Also get rid of cast to void and signed/unsigned conversion. Now return pointer to per packet data (rather than the header) which simplifies use by code setting up the packet data.

2017-12-03net: phy: realtek: add utility functions to read/write page addressesMartin Blumenstingl1-30/+53
Realtek PHYs implement the concept of so-called "extension pages". The reason for this is probably because these PHYs expose more registers than available in the standard address range. After all read/write operations on such a page are done the driver should switch back to page 0 where the standard MII registers (such as MII_BMCR) are available. When referring to such a register the datasheets of RTL8211E and RTL8211F always specify: - the page / "ext. page" which has to be written to RTL821x_PAGE_SELECT - an address (sometimes also called reg) These new utility functions make the existing code easier to read since it removes some duplication (switching back to page 0 is done within the new helpers for example).

2017-12-02openvswitch: do not propagate headroom updates to internal portPaolo Abeni1-8/+1
After commit 3a927bc7cf9d ("ovs: propagate per dp max headroom to all vports") the need_headroom for the internal vport is updated accordingly to the max needed headroom in its datapath. That avoids the pskb_expand_head() costs when sending/forwarding packets towards tunnel devices, at least for some scenarios. We still require such copy when using the ovs-preferred configuration for vxlan tunnels: br_int / \ tap vxlan (remote_ip:X) br_phy \ NIC where the route towards the IP 'X' is via 'br_phy'. When forwarding traffic from the tap towards the vxlan device, we will call pskb_expand_head() in vxlan_build_skb() because br-phy->needed_headroom is equal to tun->needed_headroom. With this change we avoid updating the internal vport needed_headroom, so that in the above scenario no head copy is needed, giving 5% performance improvement in UDP throughput test. As a trade-off, packets sent from the internal port towards a tunnel device will now experience the head copy overhead. The rationale is that the latter use-case is less relevant performance-wise.

2017-12-01rds: tcp: atomically purge entries from rds_tcp_conn_list during netns deleteSowmini Varadhan2-2/+8
The rds_tcp_kill_sock() function parses the rds_tcp_conn_list to find the rds_connection entries marked for deletion as part of the netns deletion under the protection of the rds_tcp_conn_lock. Since the rds_tcp_conn_list tracks rds_tcp_connections (which have a 1:1 mapping with rds_conn_path), multiple tc entries in the rds_tcp_conn_list will map to a single rds_connection, and will be deleted as part of the rds_conn_destroy() operation that is done outside the rds_tcp_conn_lock. The rds_tcp_conn_list traversal done under the protection of rds_tcp_conn_lock should not leave any doomed tc entries in the list after the rds_tcp_conn_lock is released, else another concurrently executiong netns delete (for a differnt netns) thread may trip on these entries.

2017-12-01rds: tcp: correctly sequence cleanup on netns deletion.Sowmini Varadhan3-6/+7
Commit 8edc3affc077 ("rds: tcp: Take explicit refcounts on struct net") introduces a regression in rds-tcp netns cleanup. The cleanup_net(), (and thus rds_tcp_dev_event notification) is only called from put_net() when all netns refcounts go to 0, but this cannot happen if the rds_connection itself is holding a c_net ref that it expects to release in rds_tcp_kill_sock. Instead, the rds_tcp_kill_sock callback should make sure to tear down state carefully, ensuring that the socket teardown is only done after all data-structures and workqs that depend on it are quiesced. The original motivation for commit 8edc3affc077 ("rds: tcp: Take explicit refcounts on struct net") was to resolve a race condition reported by syzkaller where workqs for tx/rx/connect were triggered after the namespace was deleted. Those worker threads should have been cancelled/flushed before socket tear-down and indeed, rds_conn_path_destroy() does try to sequence this by doing /* cancel cp_send_w */ /* cancel cp_recv_w */ /* flush cp_down_w */ /* free data structures */ Here the "flush cp_down_w" will trigger rds_conn_shutdown and thus invoke rds_tcp_conn_path_shutdown() to close the tcp socket, so that we ought to have satisfied the requirement that "socket-close is done after all other dependent state is quiesced". However, rds_conn_shutdown has a bug in that it *always* triggers the reconnect workq (and if connection is successful, we always restart tx/rx workqs so with the right timing, we risk the race conditions reported by syzkaller). Netns deletion is like module teardown- no need to restart a reconnect in this case. We can use the c_destroy_in_prog bit to avoid restarting the reconnect.

2017-12-01tipc: fall back to smaller MTU if allocation of local send skb failsJon Maloy4-13/+55
When sending node local messages the code is using an 'mtu' of 66060 bytes to avoid unnecessary fragmentation. During situations of low memory tipc_msg_build() may sometimes fail to allocate such large buffers, resulting in unnecessary send failures. This can easily be remedied by falling back to a smaller MTU, and then reassemble the buffer chain as if the message were arriving from a remote node. At the same time, we change the initial MTU setting of the broadcast link to a lower value, so that large messages always are fragmented into smaller buffers even when we run in single node mode. Apart from obtaining the same advantage as for the 'fallback' solution above, this turns out to give a significant performance improvement. This can probably be explained with the __pskb_copy() operation performed on the buffer for each recipient during reception. We found the optimal value for this, considering the most relevant skb pool, to be 3744 bytes.

2017-11-30vmxnet3: increase default rx ring sizesShrikrishna Khare1-4/+4
There are several reasons for increasing the receive ring sizes: 1. The original ring size of 256 was chosen about 10 years ago when vmxnet3 was first created. At that time, 10Gbps Ethernet was not prevalent and servers were dominated by 1Gbps Ethernet. Now 10Gbps is common place, and higher bandwidth links -- 25Gbps, 40Gbps, 50Gbps -- are starting to appear. 256 Rx ring entries are simply not enough to keep up with higher link speed when there is a burst of network frames coming from these high speed links. Even with full MTU size frames, they are gone in a short time. It is also more common to have a mix of frame sizes, and more likely bi-modal distribution of frame sizes so the average frame size is not close to full MTU. If we consider average frame size of 800B, 1024 frames that come in a burst takes ~0.65 ms to arrive at 10Gbps. With 256 entires, it takes ~0.16 ms to arrive at 10Gbps. At 25Gbps or 40Gbps, this time is reduced accordingly. 2. On a hypervisor where there are many VMs and CPU is over committed, i.e. the number of VCPUs is more than the number of VCPUs, each PCPU is in effect time shared between multiple VMs/VCPUs. The time granularity at which this multiplexing occurs is typically coarser than between processes on a guest OS. Trying to time slice more finely is not efficient, for example, if memory cache is barely warmed up when switching from one VM to another occurs. This CPU overcommit adds delay to when the driver in a VM can service incoming packets. Whether CPU is over committed really depends on customer workloads. For certain situations, it is very common. For example, workloads of desktop VMs and product testing setups. Consolidation and sharing is what drives efficiency of a customer setup for such workloads. In these situations, the raw network bandwidth may not be very high, but the delays between when a VM is running or not running can also be relatively long.

2017-11-30net/reuseport: drop legacy codePaolo Abeni5-55/+15
Since commit e32ea7e74727 ("soreuseport: fast reuseport UDP socket selection") and commit c125e80b8868 ("soreuseport: fast reuseport TCP socket selection") the relevant reuseport socket matching the current packet is selected by the reuseport_select_sock() call. The only exceptions are invalid BPF filters/filters returning out-of-range indices. In the latter case the code implicitly falls back to using the hash demultiplexing, but instead of selecting the socket inside the reuseport_select_sock() function, it relies on the hash selection logic introduced with the early soreuseport implementation. With this patch, in case of a BPF filter returning a bad socket index value, we fall back to hash-based selection inside the reuseport_select_sock() body, so that we can drop some duplicate code in the ipv4 and ipv6 stack. This also allows faster lookup in the above scenario and will allow us to avoid computing the hash value for successful, BPF based demultiplexing - in a later patch.
