This patch adds the NETIF_F_IPV6_CSUM to the driver's features to enable UDP/TCP checksum over IPv6. No extra configuration of the engine is needed on top of the IPv4 counterpart, which already is in the features list (NETIF_F_IP_CSUM).

This patch sets the Tx FIFO data size on port 0 to 10kB. This prepares the PPv2 driver for the Jumbo frame support addition as the hardware will need big enough Tx FIFO buffers when dealing with frames going through an interface with an MTU of 9000.

The buffer free routine is updated to release only given a number of buffers, and the destroy routine now checks the actual number of buffers in the (BPPI and BPPE) HW counters before draining the pools. This change helps getting jumbo frames support.

These pernet_operations register and unregister sysctl. nf_conntrack_l4proto_gre4->init_net is simple memory initializer. Also, exit method removes gre keymap_list, which is per-net.

These pernet_operations register and unregister two conntrack notifiers, and they seem to be safe to be executed in parallel. General/not related to async pernet_operations JFI: ctnetlink_net_exit_batch() actions are grouped in batch, and this could look like there is synchronize_rcu() is forgotten. But there is synchronize_rcu() on module exit patch (in ctnetlink_exit()), so this batch may be reworked as simple .exit method.

These pernet_operations initialize and destroy net_generic(net, ip_set_net_id)-related data. Since ip_set is under CONFIG_IP_SET, it's easy to watch drivers, which depend on this config. All of them are in net/netfilter/ipset directory, except of net/netfilter/xt_set.c. There are no more drivers, which use ip_set, and all of the above don't register another pernet_operations. Also, there are is no indirect users, as header file include/linux/netfilter/ipset/ip_set.h does not define indirect users by something like this: #ifdef CONFIG_IP_SET extern func(void); #else static inline func(void); #endif So, there are no more pernet operations, dereferencing net_generic(net, ip_set_net_id). ip_set_net_ops are OK to be executed in parallel for several net, so we mark them as async.

These pernet_operations initialize and destroy pernet net_generic(net, fou_net_id) list. The rest of net_generic(net, fou_net_id) accesses may happen after netlink message, and in-tree pernet_operations do not send FOU_GENL_NAME messages.

These pernet_operations create and destroy net::dccp::v4_ctl_sk. It looks like another pernet_operations don't want to send dccp packets to dying or creating net.

These pernet_operations have a deal with cgw_list, and the rest of accesses are made under rtnl_lock(). The only exception is cgw_dump_jobs(), which is accessed under rcu_read_lock(). cgw_dump_jobs() is called on netlink request, and it does not seem, foreign pernet_operations want to send a net such the messages. So, we mark them as async. Signed-off-by: Kirill Tkhai <ktkhai@virtuozzo.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Init method just allocates memory for new cfg, and assigns net_generic(net, caif_net_id). Despite there is synchronize_rcu() on error path in cfcnfg_create(), in real this function does not use global lists, so it looks like this synchronize_rcu() is some legacy inheritance. Exit method removes caif devices under rtnl_lock(). There could be a problem, if someone from foreign net pernet_operations dereference caif_net_id of this net. It's dereferenced in get_cfcnfg() and caif_device_list(). get_cfcnfg() is used from netdevice notifiers, where they are called under rtnl_lock(). The notifiers can't be called from foreign nets pernet_operations. Also, it's used from caif_disconnect_client() and from caif_connect_client(). The both of the functions work with caif socket, and there is the only possibility to have a socket, when the net is dead. This may happen only of the socket was created as kern using sk_alloc(). Grep by PF_CAIF shows we do not create kern caif sockets, so get_cfcnfg() is safe. caif_device_list() is used in netdevice notifiers and exit method under rtnl lock. Also, from caif_get() used in the netdev notifiers and in caif_flow_cb(). The last item is skb destructor. Since there are no kernel caif sockets nobody can send net a packet in parallel with init/exit, so this is also safe. So, these pernet_operations are safe to be async.

These pernet_operations use nf_log_set() and nf_log_unset() in their methods: nf_log_bridge_net_ops nf_log_arp_net_ops nf_log_ipv4_net_ops nf_log_ipv6_net_ops nf_log_netdev_net_ops Nobody can send such a packet to a net before it's became registered, nobody can send a packet after all netdevices are unregistered.

These pernet_operations use ebt_register_table() and ebt_unregister_table() to act on the tables, which are used as argument in ebt_do_table(), called from ebtables hooks. Since there are no net-related bridge packets in-flight, when the init and exit methods are called, these pernet_operations are safe to be executed in parallel with any other.

LRO and RX-FCS offloads cannot be enabled at the same time since it is not clear what should happen to the FCS of each coalesced packet. The FCS is not really part of the TCP payload, hence cannot be merged into one big packet. On the other hand, providing one big LRO packet with one FCS contradicts the RX-FCS feature goal. Use the fix features mechanism in order to prevent intersection of the features and drop LRO in case RX-FCS is requested. Enabling RX-FCS while LRO is enabled will result in: $ ethtool -K ens6 rx-fcs on Actual changes: large-receive-offload: off [requested on] rx-fcs: on Signed-off-by: Gal Pressman <galp@mellanox.com> Reviewed-by: Tariq Toukan <tariqt@mellanox.com> Signed-off-by: David S.

XDP_REDIRECT support for mergeable buffer was removed since commit 7324f539 ("virtio_net: disable XDP_REDIRECT in receive_mergeable() case"). This is because we don't reserve enough tailroom for struct skb_shared_info which breaks XDP assumption. So this patch fixes this by reserving enough tailroom and using fixed size of rx buffer.
