IEEE 802.15.4 and Bluetooth networking stacks share 6lowpan compression code. Instead of introducing Makefile/Kconfig hacks, build this code as a separate module referenced from both ieee802154 and bluetooth modules. This fixes the following build error observed in some kernel configurations: net/built-in.o: In function `header_create': 6lowpan.c:(.text+0x166149): undefined reference to `lowpan_header_compress' net/built-in.o: In function `bt_6lowpan_recv': (.text+0x166b3c): undefined reference to `lowpan_process_data' Reported-by:

Currently, we don't rename the upper/lower_ifc symlinks in /sys/class/net/*/ , which might result stale/duplicate links/names. Fix this by adding netdev_adjacent_rename_links(dev, oldname) which renames all the upper/lower interface's links to dev from the upper/lower_oldname to the new name. We don't need a rollback because only we control these symlinks and if we fail to rename them - sysfs will anyway complain. Reported-by:

The i40e Physical Function (PF) driver will allow the Virtual Function (VF) driver to configure its own VLAN filters if no port VLAN filter has been configured. This leads to the possibility of the administrator setting a port VLAN filter for the VF after the VF has already configured its own VLAN filters. This leads to a conflict that can only be resolved by reloading the VF driver. When the conflicting administrative command is detected in setting the port VLAN then log a message indicating to the system administrator that he must now reload the VF driver for the new port VLAN settings to take effect.

Changelog: v1->v2: - Removed BUG_ON as it's not needed. v2->v3: - Removed dev->reg_state check for netns. v3->v4: - Removed list_del(), we seem to do it in some places and in some others not; we agreed it's not really necessary. - Split patch into 2 patches, notifier part and module unload cleanup part. ==================== Reviewed-by:Cong Wang <cwang@twopensource.com> Signed-off-by:

We should use vxlan_dellink() handler in vxlan_exit_net(), since i) we're not in fast-path and we should be consistent in dismantle just as we would remove a device through rtnl ops, and more importantly, ii) in case future code will kfree() memory in vxlan_dellink(), we would leak it right here unnoticed. Therefore, do not only half of the cleanup work, but make it properly. Signed-off-by:

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: -

Aaron Brown says: ==================== Intel Wired LAN Driver Updates, ixgbe: Add LER support The following patches add Live Error Recovery (LER) support to the ixgbe driver. This support also improves behavior in Thunderbolt environments. This involves checking all register reads for a value of all ones and when that is seen, to read the status register, which should never properly return all ones, to confirm whether the received value was correct. When this detects a removal, the hw_addr field is cleared to indicate the removal. This then blocks subsequent access to the device registers. All register access macros have been changed to static inline functions and all register accesses now use them.· Macro versions are temporarily provided. The __IXGBE_DOWN bit is no longer overloaded to also mean that device removal has been initiated. Now the bit can be used to protect ixgbe_down from multiple entry via test_and_set_bit. A needed smp_mb__before_clear_bit was also added. V2 Changes: - Use ACCESS_ONCE where needed, thanks to Ben Hutchings - Fix crash on module removal - Use boolean values for boolean returns instead of 0 and 1 - Reword Kconfig help text V3 Changes: - Drop config option, per David Miller - Drop tail register write checks, per Alexander Duyck - Change writeq implementation to a static inline, thanks to Joe Perches V4 Changes: - Change __IXGBE_REMOVE to __IXGBE_REMOVING, per Scott Feldman's comment - Add #define writeq writeq, per Alexander Duyck - Change static inline functions to lower case, per David Miller - Use new lower case names in added and modified register accesses - Provide temporary upper case macros for register access functions - Change IXGBE_REMOVED from macro to static inline and change references - Correct IXGBE_WRITE_FLUSH to properly enclose parameter expansion ==================== Signed-off-by: -

Additional checks are needed for a detected removal not to cause problems. Some involve simply avoiding a lot of stuff that can't do anything good, and also cases where the phony return value can cause problems. In addition, down the adapter when the removal is sensed. Signed-off-by:

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. Signed-off-by:

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.

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. Signed-off-by:

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. Signed-off-by:
