2020-11-03net: bonding, dummy, ifb, team: advertise NETIF_F_GSO_SOFTWAREAlexander Lobakin1-1/+1
Virtual netdevs should use NETIF_F_GSO_SOFTWARE to forward GSO skbs as-is and let the final drivers deal with them when supported. Also remove NETIF_F_GSO_UDP_L4 from bonding and team drivers as it's now included in the "software" list.

2018-03-31net: Do not take net_rwsem in __rtnl_link_unregister()Kirill Tkhai1-0/+2
This function calls call_netdevice_notifier(), which also may take net_rwsem. So, we can't use net_rwsem here. This patch makes callers of this functions take pernet_ops_rwsem, like register_netdevice_notifier() does. This will protect the modifications of net_namespace_list, and allows notifiers to take it (they won't have to care about context). Since __rtnl_link_unregister() is used on module load and unload (which are not frequent operations), this looks for me better, than make all call_netdevice_notifier() always executing in "protected net_namespace_list" context. Also, this fixes the problem we had a deal in 328fbe747ad4 "Close race between {un, }register_netdevice_notifier and ...", and guarantees __rtnl_link_unregister() does not skip exitting net.

2017-09-25net: remove MTU limits for dummy and ifb deviceZhang Shengju1-1/+1
These two drivers (dummy and ifb) call ether_setup(), after commit 61e84623ace3 ("net: centralize net_device min/max MTU checking"), the range of mtu is [min_mtu, max_mtu], which is [68, 1500] by default. These two devices should not have limits on MTU. This patch set their min_mtu/max_mtu to 0. So that dev_set_mtu() will not check the mtu range, and can be set with any value.

2017-06-07net: Fix inconsistent teardown and release of private netdev state.David S. Miller1-2/+2
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>

This enables developing code that uses SOF_TIMESTAMPING_TX_SOFTWARE by using localhost addresses (without needing to send packets outside), as well as enabling unit and functional testing of TX timestamping code without needing hardware support or network access.

2017-01-24net: dummy: Introduce dummy virtual functionsPhil Sutter1-2/+215
The idea for this was born when testing VF support in iproute2 which was impeded by hardware requirements. In fact, not every VF-capable hardware driver implements all netdev ops, so testing the interface is still hard to do even with a well-sorted hardware shelf. To overcome this and allow for testing the user-kernel interface, this patch allows to turn dummy into a PF with a configurable amount of VFs. Since my patch series 'bus-agnostic-num-vf' has been accepted, implementing the required interfaces is pretty straightforward: Iff 'num_vfs' module parameter was given a value >0, a dummy bus type is being registered which implements the 'num_vf()' callback. Additionally, a dummy parent device common to all dummy devices is registered which sits on the above dummy bus. Joint work with Sabrina Dubroca.

2013-11-06net: Explicitly initialize u64_stats_sync structures for lockdepJohn Stultz1-0/+6
In order to enable lockdep on seqcount/seqlock structures, we must explicitly initialize any locks. The u64_stats_sync structure, uses a seqcount, and thus we need to introduce a u64_stats_init() function and use it to initialize the structure. This unfortunately adds a lot of fairly trivial initialization code to a number of drivers. But the benefit of ensuring correctness makes this worth while. Because these changes are required for lockdep to be enabled, and the changes are quite trivial, I've not yet split this patch out into 30-some separate patches, as I figured it would be better to get the various maintainers thoughts on how to best merge this change along with the seqcount lockdep enablement.

2007-10-10[NET]: Nuke SET_MODULE_OWNER macro.Ralf Baechle1-1/+0
It's been a useless no-op for long enough in 2.6 so I figured it's time to remove it. The number of people that could object because they're maintaining unified 2.4 and 2.6 drivers is probably rather small.

2007-07-11[RTNETLINK]: rtnl_link: allow specifying initial device addressPatrick McHardy1-0/+12
Drivers need to validate the initial addresses in their netlink attribute validation function or manually reject them if they can't support this. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-07-11[RTNETLINK]: rtnl_link API simplificationPatrick McHardy1-54/+3
All drivers need to unregister their devices in the module unload function. While doing so they must hold the rtnl and atomically unregister the rtnl_link ops as well. This makes the rtnl_link_unregister function that takes the rtnl itself completely useless. Provide default newlink/dellink functions, make __rtnl_link_unregister and rtnl_link_unregister unregister all devices with matching rtnl_link_ops and change the existing users to take advantage of that.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
