2014-01-16neigh: use NEIGH_VAR_INIT in ndo_neigh_setup functions.Jiri Pirko2-2/+7
When ndo_neigh_setup is called, the bitfield used by NEIGH_VAR_SET is not initialized yet. This might cause confusion for the people who use NEIGH_VAR_SET in ndo_neigh_setup. So rather introduce NEIGH_VAR_INIT for usage in ndo_neigh_setup. Signed-off-by: Jiri Pirko <jiri@resnulli.us> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-01-15ixgbe: Clear head write-back registers on VF resetAlexander Duyck2-0/+17
The Tx head write-back registers are not cleared during an FLR or VF reset. As a result a configuration that had head write-back enabled can leave the registers set after the driver is unloaded. If the next driver loaded doesn't use the write-back registers this can lead to a bad configuration where head write-back is enabled, but the driver didn't request it. To avoid this situation the PF should be resetting the Tx head write-back registers when the VF requests a reset.

2014-01-15ipv6 addrconf: don't cleanup prefix route for IFA_F_NOPREFIXROUTEThomas Haller1-75/+109
Refactor the deletion/update of prefix routes when removing an address. Now also consider IFA_F_NOPREFIXROUTE and if there is an address present with this flag, to not cleanup the route. Instead, assume that userspace is taking care of this route. Also perform the same cleanup, when userspace changes an existing address to add NOPREFIXROUTE (to an address that didn't have this flag). This is done because when the address was added, a prefix route was created for it. Since the user now wants to handle this route by himself, we cleanup this route. This cleanup of the route is not totally robust. There is no guarantee, that the route we are about to delete was really the one added by the kernel. This behavior does not change by the patch, and in practice it should work just fine. Signed-off-by: Thomas Haller <thaller@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-01-15ipv6 addrconf: add IFA_F_NOPREFIXROUTE flag to suppress creation of IP6 routesThomas Haller2-6/+14
When adding/modifying an IPv6 address, the userspace application needs a way to suppress adding a prefix route. This is for example relevant together with IFA_F_MANAGERTEMPADDR, where userspace creates autoconf generated addresses, but depending on on-link, no route for the prefix should be added.

2014-01-14net: vxlan: when lower dev unregisters remove vxlan dev as wellDaniel Borkmann1-2/+46
We can create a vxlan device with an explicit underlying carrier. In that case, when the carrier link is being deleted from the system (e.g. due to module unload) we should also clean up all created vxlan devices on top of it since otherwise we're in an inconsistent state in vxlan device. In that case, the user needs to remove all such devices, while in case of other virtual devs that sit on top of physical ones, it is usually the case that these devices do unregister automatically as well and do not leave the burden on the user. This work is not necessary when vxlan device was not created with a real underlying device, as connections can resume in that case when driver is plugged again. But at least for the other cases, we should go ahead and do the cleanup on removal. We don't register the notifier during vxlan_newlink() here since I consider this event rather rare, and therefore we should not bloat vxlan's core structure unecessary. Also, we can simply make use of unregister_netdevice_many() to batch that. fdb is flushed upon ndo_stop(). E.g. `ip -d link show vxlan13` after carrier removal before this patch: 5: vxlan13: <BROADCAST,MULTICAST> mtu 1450 qdisc noop state DOWN mode DEFAULT group default link/ether 1e:47:da:6d:4d:99 brd ff:ff:ff:ff:ff:ff promiscuity 0 vxlan id 13 group 239.0.0.10 dev 2 port 32768 61000 ageing 300 ^^^^^ Signed-off-by: Daniel Borkmann <dborkman@redhat.com> Signed-off-by: David S.

2014-01-14ixgbe: Check register reads for adapter removalMark Rustad3-5/+53
Check all register reads for adapter removal by checking the status register after any register read that returns 0xFFFFFFFF. Since the status register will never return 0xFFFFFFFF unless the adapter is removed, such a value from a status register read confirms the removal.

2014-01-14ixgbe: Make ethtool register test use accessorsMark Rustad1-51/+47
Make the ethtool register test use the normal register accessor functions. Also eliminate macros used for calling register test functions to make error exits clearer. Use boolean values for boolean returns instead of 0 and 1.

2014-01-14ixgbe: Use static inlines instead of macrosMark Rustad3-12/+33
Kernel coding standard prefers static inline functions instead of macros, so use them for register accessors. This is to prepare for adding LER, Live Error Recovery, checks to those accessors. Temporarily provide macros for calling the new static inline accessors until all references are changed.

2014-01-14ixbge: Protect ixgbe_down with __IXGBE_DOWN bitMark Rustad1-1/+3
The ixgbe_down function can now prevent multiple executions by doing test_and_set_bit on __IXGBE_DOWN. This did not work before introduction of the __IXGBE_REMOVING bit, because of overloading of __IXGBE_DOWN. Also add smp_mb__before_clear_bit call before clearing the __IXGBE_DOWN bit.

2014-01-14ixgbe: Indicate removal state explicitlyMark Rustad2-4/+9
Add a bit, __IXGBE_REMOVING, to indicate that the module is being removed. The __IXGBE_DOWN bit had been overloaded for this purpose, but that leads to trouble. A few places now check both __IXGBE_DOWN and __IXGBE_REMOVE. Notably, setting either bit will prevent service task execution.
