An issue in the code mapping the skb fragments into scatter-gather frames was evidentiated by netperf TCP_SENDFILE tests. The size was set wrong for all fragments but the first, affecting the transmission of any skb with more than one fragment. Signed-off-by:

Kirill Tkhai says: ==================== Converting pernet_operations (part #3) This patchset continues to review and to convert pernet_operations to async. Where it is possible, they are grouped by type of actions init/exit methods ([1/28], for example). I hope this will make the review a little bit easier. The changes are tree-wide: in net, fs, drivers and security. ==================== Signed-off-by: -

These pernet_operations only register and unregister nf hooks. So, they are able to be marked as async. Signed-off-by:

These pernet_operations register and unregister nf hooks. Also they populate and depopulate ila_net_id-pointed hash table. The table is changed by hooks during skb processing and via netlink request. It looks impossible for another net pernet_operations to force the table reading or writing, so, they are able to be marked as async. Signed-off-by:

These pernet_operations unregister ipvlan net hooks. nf_unregister_net_hooks() removes hooks one-by-one, and then frees the memory via rcu. This looks similar to that happens, when a new hooks is added: allocation of bigger memory region, copy of old content, and rcu freeing the old memory. So, all of net code should be well with this behavior. Also at the time of hook unregistering, there are no packets, and foreign net pernet_operations are not interested in others hooks. So, we mark them as async. Signed-off-by:

These pernet_operations have only exit method, which moves devices from cfg802154_rdev_list to init_net. This may occur in any time from nl802154_wpan_phy_netns(), so we are nice with rtnl_lock() synchronization. Signed-off-by:

These pernet_operations are similar to bond_net_ops. Exit methods unregisters all net ipgre/ipgre_tap/erspan/vti/ipip devices, and it looks like another pernet_operations are not interested in foreign net ipgre/ipgre_tap/erspan/vti/ipip list. Init method also does not intersect with something pernet-specific. So, it's possible to mark them async. Signed-off-by:

These pernet_operations are from net/sched directory, and they call only tc_action_net_init() and tc_action_net_exit(): bpf_net_ops connmark_net_ops csum_net_ops gact_net_ops ife_net_ops ipt_net_ops xt_net_ops mirred_net_ops nat_net_ops pedit_net_ops police_net_ops sample_net_ops simp_net_ops skbedit_net_ops skbmod_net_ops tunnel_key_net_ops vlan_net_ops 1)tc_action_net_init() just allocates and initializes per-net memory. 2)There should not be in-flight packets at the time of tc_action_net_exit() call, or another pernet_operations send packets to dying net (except netlink). So, it seems they can be marked as async. Signed-off-by:

We no longer depend on IPV6, but that now causes a link error with CONFIG_IPV6=m and CONFIG_IPVLAN=y: drivers/net/ipvlan/ipvlan_core.o: In function `ipvlan_queue_xmit': ipvlan_core.c:(.text+0x1440): undefined reference to `ip6_route_output_flags' drivers/net/ipvlan/ipvlan_core.o: In function `ipvlan_l3_rcv': ipvlan_core.c:(.text+0x1818): undefined reference to `ip6_route_input_lookup' This adds back the dependency on IPV6, with the option of building without IPV6, but forcing IPVLAN to be a module when IPV6 is a module.

Jeff Kirsher says: ==================== 10GbE Intel Wired LAN Driver Updates 2018-02-26 This series contains updates to ixgbe and ixgbevf only. Colin Ian King cleans up redundant variable assignments. Tonghao Zhang updates ixgbe to avoid writing to the hardware when the redirection table has not changed. Jake fixes the driver logic for checking and clearing receive timestamp hangs so that when the PTP_RX_TIMESTAMP_IN_REGISTER flag is set, we no longer need to check for receive timestamp hangs, which in turn will stop the spurious log messages. Emil updates ixgbevf with several features and improvements done in other drivers, starting with the handling of page addresses so that we always refer to them using a void pointer. Added a 'legacy-rx' flag to allow switching between the old and new receive code paths. Added support for using 3K buggers in order 1 page. Updated the driver to ensure that calls to ixgbevf_open() are rtnl lock protected and improved the error handling when setting up multiple queues. Added support for providing a buffer with head room and tail room to allow for shared info, NET_SKB_PAD, and NET_IP_ALIGN, so that we can start using build_skb to build frames instead of using memcpy() the headers. Updated the logic of handling rings closer to ixgbe. Consolidated the receive paths to reduce duplication when we expand them in the future. Added build_skb() support to ixgbevf. ==================== Signed-off-by:

Add missing printk severity levels by adopting pr_foo() calls for the platform_driver and dev_foo() calls for the nubus_driver. Avoid KERN_CONT usage as per advice from checkpatch.

It appears that the single port Ether controllers having TSU (like SH7734/ R8A7740) need the same kind of treating in sh_eth_tsu_init() as R7S72100 currently has -- they also don't have the TSU registers related e.g. to passing the frames between ports. Add the 'sh_eth_cpu_data::dual_port' flag and use it as a new criterion for taking a "short path" in the TSU init sequence in order to avoid writing to the non-existent registers...
