net: bonding, dummy, ifb, team: advertise NETIF_F_GSO_SOFTWARE

2020-11-04T00:53:55+00:00

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.

net/dummy: Ditch driver and module versions

2020-02-24T19:23:36+00:00

Delete constant driver and module versions in favor of standard global version which is unique to whole kernel. Signed-off-by: Leon Romanovsky Signed-off-by: David S. Miller

net: dummy: use standard dev_lstats_add() and dev_lstats_read()

2019-11-08T04:03:08+00:00

This driver can simply use the common infrastructure instead of duplicating it. This cleanup will ease u64_stats_t adoption in a single location. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

treewide: Add SPDX license identifier for more missed files

2019-05-21T08:50:45+00:00

Add SPDX license identifiers to all files which: - Have no license information of any form - Have MODULE_LICENCE("GPL*") inside which was used in the initial scan/conversion to ignore the file These files fall under the project license, GPL v2 only. The resulting SPDX license identifier is: GPL-2.0-only Signed-off-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman

net: dummy: use generic helper to report timestamping info

2019-04-12T23:26:37+00:00

For reporting the common set of SW timestamping capabilities, use ethtool_op_get_ts_info() instead of re-implementing it. Signed-off-by: Julian Wiedmann Signed-off-by: David S. Miller

net: Do not take net_rwsem in __rtnl_link_unregister()

2018-04-01T02:24:58+00:00

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.

net: dummy: remove fake SR-IOV functionality

netdevsim driver seems like a better place for fake SR-IOV functionality. Remove the code previously added to dummy. Signed-off-by: Jakub Kicinski Reviewed-by: Quentin Monnet Acked-by: Phil Sutter Signed-off-by: Daniel Borkmann

net: remove MTU limits for dummy and ifb device

2017-09-25T23:26:09+00:00

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.

dummy: declare dummy devices as enumerated devices

2017-09-18T18:28:36+00:00

Dummy device name is enumerated by the kernel, let user space be aware of the naming scheme used by dummy devices: (visible in /sys/class/net//name_assign_type). Signed-off-by: Zhang Shengju Signed-off-by: David S. Miller
