drivers/net: macvtap and tun depend on INET

2014-10-31T03:50:26+00:00

These drivers now call ipv6_proxy_select_ident(), which is defined only if CONFIG_INET is enabled. However, they have really depended on CONFIG_INET for as long as they have allowed sending GSO packets from userland.

netpoll: Remove dead packet receive code (CONFIG_NETPOLL_TRAP)

2014-03-17T19:48:12+00:00

The netpoll packet receive code only becomes active if the netpoll rx_skb_hook is implemented, and there is not a single implementation of the netpoll rx_skb_hook in the kernel. All of the out of tree implementations I have found all call netpoll_poll which was removed from the kernel in 2011, so this change should not add any additional breakage. There are problems with the netpoll packet receive code. __netpoll_rx does not call dev_kfree_skb_irq or dev_kfree_skb_any in hard irq context. netpoll_neigh_reply leaks every skb it receives. Reception of packets does not work successfully on stacked devices (aka bonding, team, bridge, and vlans). Given that the netpoll packet receive code is buggy, there are no out of tree users that will be merged soon, and the code has not been used for in tree for a decade let's just remove it. Reverting this commit can server as a starting point for anyone who wants to resurrect netpoll packet reception support. Acked-by: Eric Dumazet Signed-off-by: "Eric W.

net: fix macvtap type name in Kconfig

virtio-net: fix build error when CONFIG_AVERAGE is not enabled

2014-01-18T02:58:38+00:00

Commit ab7db91705e9 ("virtio-net: auto-tune mergeable rx buffer size for improved performance") introduced a virtio-net dependency on EWMA. The inclusion of EWMA is controlled by CONFIG_AVERAGE. Fix build error when CONFIG_AVERAGE is not enabled by adding select AVERAGE to virtio-net's Kconfig entry. Build failure reported using config make ARCH=s390 defconfig.

packet: nlmon: virtual netlink monitoring device for packet sockets

2013-06-24T23:39:05+00:00

Currently, there is no good possibility to debug netlink traffic that is being exchanged between kernel and user space. Therefore, this patch implements a netlink virtual device, so that netlink messages will be made visible to PF_PACKET sockets. Once there was an approach with a similar idea [1], but it got forgotten somehow. I think it makes most sense to accept the "overhead" of an extra netlink net device over implementing the same functionality from PF_PACKET sockets once again into netlink sockets. We have BPF filters that can already be easily applied which even have netlink extensions, we have RX_RING zero-copy between kernel- and user space that can be reused, and much more features. So instead of re-implementing all of this, we simply pass the skb to a given PF_PACKET socket for further analysis. Another nice benefit that comes from that is that no code needs to be changed in user space packet analyzers (maybe adding a dissector, but not more), thus out of the box, we can already capture pcap files of netlink traffic to debug/troubleshoot netlink problems.

net: Move MII out from under NET_CORE and hide it

2013-06-20T05:22:56+00:00

All drivers that select MII also need to select NET_CORE because MII depends on it. This is a bit ridiculous because NET_CORE is just a menu option that doesn't enable any code by itself. There is also no need for it to be a visible option, since its users all select it. Signed-off-by: Ben Hutchings Acked-by: Jeff Kirsher Signed-off-by: David S. Miller

VXLAN: Fix vxlan stats handling.

2013-03-26T16:27:18+00:00

Fixes bug in VXLAN code where is iptunnel_xmit() called with NULL dev->tstats. This bug was introduced in commit 6aed0c8bf7d2f389b (tunnel: use iptunnel_xmit() again). Following patch fixes bug by setting dev->tstats. It uses ip_tunnel module code to share stats function.

Pull networking fixes from David Miller: 1) ping_err() ICMP error handler looks at wrong ICMP header, from Li Wei. 2) TCP socket hash function on ipv6 is too weak, from Eric Dumazet. 3) netif_set_xps_queue() forgets to drop mutex on errors, fix from Alexander Duyck. 4) sum_frag_mem_limit() can deadlock due to lack of BH disabling, fix from Eric Dumazet. 5) TCP SYN data is miscalculated in tcp_send_syn_data(), because the amount of TCP option space was not taken into account properly in this code path. Fix from yuchung Cheng. 6) MLX4 driver allocates device queues with the wrong size, from Kleber Sacilotto. 7) sock_diag can access past the end of the sock_diag_handlers[] array, from Mathias Krause. 8) vlan_set_encap_proto() makes incorrect assumptions about where skb->data points, rework the logic so that it works regardless of where skb->data happens to be. From Jesse Gross. 9) Fix gianfar build failure with NET_POLL enabled, from Paul Gortmaker. 10) Fix Ipv4 ID setting and checksum calculations in GRE driver, from Pravin B Shelar. 11) bgmac driver does: int i; for (i = 0; ...; ...) { ... for (i = 0; ...; ...) { effectively corrupting the outer loop index, use a seperate variable for the inner loops.
