* batman-adv: fix batadv_interface_tx()'s return typeLuc Van Oostenryck2018-04-251-2/+2
| | | | | | | | | | | | | The method ndo_start_xmit() is defined as returning an 'netdev_tx_t', which is a typedef for an enum type, but the implementation in this driver returns an 'int'. Fix this by returning 'netdev_tx_t' in this driver too.

* batman-adv: Avoid old nodes disabling multicast optimizations completelyLinus Lüssing2018-04-221-1/+0Star
| | | | | | | | | | | | | Instead of disabling multicast optimizations mesh-wide once a node with no multicast optimizations capabilities joins the mesh, do the following: Just insert such nodes into the WANT_ALL_IPV4/IPV6 lists. This is sufficient to avoid multicast packet loss to such unsupportive nodes.

| * batman-adv: fix packet checksum in receive pathMatthias Schiffer2018-02-251-7/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | eth_type_trans() internally calls skb_pull(), which does not adjust the skb checksum; skb_postpull_rcsum() is necessary to avoid log spam of the form "bat0: hw csum failure" when packets with CHECKSUM_COMPLETE are received. Note that in usual setups, packets don't reach batman-adv with CHECKSUM_COMPLETE (I assume NICs bail out of checksumming when they see batadv's ethtype?), which is why the log messages do not occur on every system using batman-adv. I could reproduce this issue by stacking batman-adv on top of a VXLAN interface.

* net: Fix inconsistent teardown and release of private netdev state.David S. Miller2017-06-071-3/+2Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Network devices can allocate reasources and private memory using netdev_ops->ndo_init(). However, the release of these resources can occur in one of two different places. Either netdev_ops->ndo_uninit() or netdev->destructor(). The decision of which operation frees the resources depends upon whether it is necessary for all netdev refs to be released before it is safe to perform the freeing. netdev_ops->ndo_uninit() presumably can occur right after the NETDEV_UNREGISTER notifier completes and the unicast and multicast address lists are flushed. netdev->destructor(), on the other hand, does not run until the netdev references all go away. Further complicating the situation is that netdev->destructor() almost universally does also a free_netdev(). This creates a problem for the logic in register_netdevice(). Because all callers of register_netdevice() manage the freeing of the netdev, and invoke free_netdev(dev) if register_netdevice() fails. If netdev_ops->ndo_init() succeeds, but something else fails inside of register_netdevice(), it does call ndo_ops->ndo_uninit(). But it is not able to invoke netdev->destructor(). This is because netdev->destructor() will do a free_netdev() and then the caller of register_netdevice() will do the same. However, this means that the resources that would normally be released by netdev->destructor() will not be. Over the years drivers have added local hacks to deal with this, by invoking their destructor parts by hand when register_netdevice() fails. Many drivers do not try to deal with this, and instead we have leaks. Let's close this hole by formalizing the distinction between what private things need to be freed up by netdev->destructor() and whether the driver needs unregister_netdevice() to perform the free_netdev(). netdev->priv_destructor() performs all actions to free up the private resources that used to be freed by netdev->destructor(), except for free_netdev(). netdev->needs_free_netdev is a boolean that indicates whether free_netdev() should be done at the end of unregister_netdevice(). Now, register_netdevice() can sanely release all resources after ndo_ops->ndo_init() succeeds, by invoking both ndo_ops->ndo_uninit() and netdev->priv_destructor(). And at the end of unregister_netdevice(), we invoke netdev->priv_destructor() and optionally call free_netdev(). Signed-off-by: David S. Miller <davem@davemloft.net>

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The network stack no longer uses the last_rx member of struct net_device since the bonding driver switched to use its own private last_rx in commit 9f242738376d ("bonding: use last_arp_rx in slave_last_rx()"). However, some drivers still (ab)use the field for their own purposes and some driver just update it without actually using it. Previously, there was an accompanying comment for the last_rx member added in commit 4dc89133f49b ("net: add a comment on netdev->last_rx") which asked drivers not to update is, unless really needed. However, this commend was removed in commit f8ff080dacec ("bonding: remove useless updating of slave->dev->last_rx"), so some drivers added later on still did update last_rx. Remove all usage of last_rx and switch three drivers (sky2, atp and smc91c92_cs) which actually read and write it to use their own private copy in netdev_priv.

Goodies for BATMAN V: ("Upgrade your BATMAN IV network to V now to get these for free!") Thanks to the split of OGMv1 into two packet types, OGMv2 and ELP that is, we can now apply the same optimizations stated above to OGMv2 packets, too. Furthermore, with BATMAN V, rebroadcasts can be reduced in certain multi interface cases, too, where BATMAN IV cannot.

| * batman-adv: move GW mode and selection class to private data structureAntonio Quartulli2016-06-301-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To reduce the field pollution in our main batadv_priv data structure we've already created some substructures so that we could group fields in a convenient manner. However gw_mode and gw_sel_class are still part of the main object. More both fields to the GW private substructure.

* | batman-adv: Clean up untagged vlan when destroying via rtnl-linkSven Eckelmann2016-06-291-0/+9
|/ | | | | | | | | | | | The untagged vlan object is only destroyed when the interface is removed via the legacy sysfs interface. But it also has to be destroyed when the standard rtnl-link interface is used.

* batman-adv: Use bool as return type for boolean functionsSven Eckelmann2016-05-101-3/+3
| | | | | | | | | | | | It is easier to understand that the returned value of a specific function doesn't have to be 0 when the functions was successful when the actual return type is bool. This is especially true when all surrounding functions with return type int use negative values to return the error code.

| | | | | | | | | | | | | When creating a soft interface, create it in the same netns as the hard interface. Replace all references to init_net with the correct name space for the interface being manipulated.

| | | | | | | | | | | | | The batX soft interface should not be moved between network name spaces. This is similar to bridges, bonds, tunnels, which are not allowed to move between network namespaces.

* batman-adv: Remove hdr_size skb size check in batadv_interface_rxSven Eckelmann2016-05-101-4/+0Star
| | | | | | | | | | | | | The callers of batadv_interface_rx have to make sure that enough data can be pulled from the skb when they read the batman-adv header. The only two functions using it are either calling pskb_may_pull with hdr_size directly (batadv_recv_bcast_packet) or indirectly via batadv_check_unicast_packet (batadv_recv_unicast_packet).
