Recent discussion around "[net-next] bonding: don't allow the master to become its slave" forced me to think about upper<->lower device connections. This patchset adds a possibility to record upper device linkage. All upper<->lower devices are converted to use this mechanism right after. That leads to dev->master removal because this info becomes redundant since "unique links" have the same value. After all changes, there is no longer possible to do: "bond->someotherdevice->samebond" Also I think that drivers like cxgb3, qlcnic, qeth would benefit by this in future by being able to get more appropriate info about l3 addresses. v1->v2: - s/unique/master/ better naming + stays closer to the history - fixed vlan err goto - original patch 15 (WARN_ON change) is squashed into the first patch - fixed netdev_unique_upper_dev_get_rcu() case of upper==NULL Jiri Pirko (15): net: introduce upper device lists macvlan: add link to upper device vlan: add link to upper device rtnetlink: remove usage of dev->master team: remove usage of netdev_set_master() bridge: remove usage of netdev_set_master() netpoll: remove usage of dev->master cxgb3: remove usage of dev->master qlcnic: guard __vlan_find_dev_deep() by rcu_read_lock qeth: ensure that __vlan_find_dev_deep() is called with rcu_read_lock vlan: remove usage of dev->master in __vlan_find_dev_deep() nes: remove usage of dev->master bonding: remove usage of dev->master net: remove no longer used netdev_set_bond_master() and netdev_set_master() net: kill dev->master drivers/infiniband/hw/nes/nes.c | 8 +- drivers/infiniband/hw/nes/nes_cm.c | 2 +- drivers/net/bonding/bond_3ad.c | 30 +-- drivers/net/bonding/bond_alb.c | 6 +- drivers/net/bonding/bond_main.c | 94 ++++---- drivers/net/bonding/bonding.h | 14 +- drivers/net/ethernet/chelsio/cxgb3/cxgb3_offload.c | 11 +- drivers/net/ethernet/qlogic/qlcnic/qlcnic_main.c | 2 + drivers/net/macvlan.c | 9 +- drivers/net/team/team.c | 13 +- drivers/s390/net/qeth_l3_main.c | 21 +- include/linux/netdevice.h | 22 +- net/8021q/vlan.c | 10 +- net/8021q/vlan_core.c | 18 +- net/bridge/br_if.c | 6 +- net/core/dev.c | 239 +++++++++++++++++--- net/core/netpoll.c | 8 +- net/core/rtnetlink.c | 45 ++-- 18 files changed, 391 insertions(+), 167 deletions(-) -- 1.7.10.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
