TIPC is currently using the field 'af_packet_priv' in struct net_device as a handle to find the bearer instance associated to the given network device. But, by doing so it is blocking other networking cleanups, such as the one discussed here: http://patchwork.ozlabs.org/patch/178044/ This commit removes this usage from TIPC. Instead, we introduce a new field, 'tipc_ptr', to the net_device structure, to serve this purpose. When TIPC bearer is enabled, the bearer object is associated to 'tipc_ptr'. When a TIPC packet arrives in the recv_msg() upcall from a networking device, the bearer object can now be obtained from 'tipc_ptr'. When a bearer is disabled, the bearer object is detached from its underlying network device by setting 'tipc_ptr' to NULL. Additionally, an RCU lock is used to protect the new pointer. Henceforth, the existing tipc_net_lock is used in write mode to serialize write accesses to this pointer, while the new RCU lock is applied on the read side to ensure that the pointer is 100% valid within its wrapped area for all readers.

struct 'tipc_media' represents the specific info that the media layer adaptors (eth_media and ib_media) expose to the generic bearer layer. We clarify this by improved commenting, and by giving the 'media_list' array the more appropriate name 'media_info_array'. There are no functional changes in this commit. Signed-off-by:

Communication media types are abstracted through the struct 'tipc_media', one per media type. These structs are allocated statically inside their respective media file. Furthermore, in order to be able to reach all instances from a central location, we keep a static array with pointers to these structs. This array is currently initialized at runtime, under protection of tipc_net_lock. However, since the contents of the array itself never changes after initialization, we can just as well initialize it at compile time and make it 'const', at the same time making it obvious that no lock protection is needed here. This commit makes the array constant and removes the redundant lock protection. Signed-off-by:

sk_buff lists are currently relased by looping over the list and explicitly releasing each buffer. We replace all occurrences of this loop with a call to kfree_skb_list(). Signed-off-by:

From: Soren Brinkmann <soren.brinkmann@xilinx.com> ==================== net: macb updates I'd really like to have Ethernet working for Zynq, so I want to at least revive this discussion regarding this patchset. And the first four patches should not even be too controversial. I didn't change anything compared to my original RFC submission, except for a typo in one of the commit messages. Handling the tx_clk as optional clock input seems a little bit weird, but it works on my Zynq platform and should be compatible with other users of macb and their DT descriptions. ==================== Signed-off-by: -

This patch makes socketpair() use error paths which do not rely on heavy-weight call to sys_close(): it's better to try to push the file descriptor to userspace before installing the socket file to the file descriptor, so that errors are catched earlier and being easier to handle. Using sys_close() seems to be the exception, while writing the file descriptor before installing it look like it's more or less the norm: eg. except for code used in init/, error handling involve fput() and put_unused_fd(), but not sys_close(). This make socketpair() usage of sys_close() quite unusual. So it deserves to be replaced by the common pattern relying on fput() and put_unused_fd() just like, for example, the one used in pipe(2) or recvmsg(2). Three distinct error paths are still needed since calling fput() on file structure returned by sock_alloc_file() will implicitly call sock_release() on the associated socket structure. Cc: David S.

Add support for yet another ARM member of the R-Car family, R-Car M2, also known as R8A7791 -- it will share the code and data with previously added R8A7790. Despite the Ether devices in these SoCs are indistinguishable at least from the driver's point of view, we do introduce a new platform device ID "r8a7791-ether" unlike the wildcard ID used for R8A7778/9 SoCs, due to newly established policy for the Renesas SoCs.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to i40e, igb, ixgbe and ixgbevf. Shannon provides a couple of i40e patches, first restricts the ethtool diag test messages by using netif_info() macro to when the hardware bit is enabled in the message level netdev message mask. Second provides a fix for when there is an out-of-range descriptor request. Kamil provides a fix for i40e by updating the loopback enum types and add information about the current loopback mode to data returned from get_link_info(). Jesse provides a fix for i40e define name that was being mis-used. I40E_ITR_NONE was being used as an ITRN register index by accident because it was easily associated with the i40e Rx ITR and friends defines, when it should be associated with the DYN_CTL register sets. Jacob provides an update for ixgbevf Kconfig description since the VF driver supports more than just the 82599 device. Don and Alex provide a cleanup patch for ixgbe to make it where head, tail, next to clean and next to use are all reset in a single function for both Tx and Rx path. Before, the code for this was spread out over several areas which made it difficult to track what the values were for each of the values. Carolyn provides two igb patches to add a media switching feature for i354 PHY's and new Media Auto Sense for 82580 devices only. Aaron Sierra provides a fix for igb to resolve an issue with the 64-bit PCI addresses being truncated because the return values of pci_resource_start() and pci_resouce_end() were being cast to unsigned long. Guenter Roeck provides two igb patches, first simplifies the code by attaching the hwmon sysfs attributes to hwmon device instead of the PCI device. Second fixes the temperature sensor attribute index by setting it to 1 instead of 0 (per hwmon ABI). ==================== Signed-off-by: -

Simplify the code. Attach hwmon sysfs attributes to hwmon device instead of pci device. Avoid race conditions caused by attributes being created after registration and provide mandatory 'name' attribute by using new hwmon API. Other cleanup: Instead of allocating memory for hwmon attributes, move attributes and all other hwmon related data into struct hwmon_buff and allocate the entire structure using devm_kzalloc. Check return value from calls to igb_add_hwmon_attr() one by one instead of logically combining them all together. Signed-off-by:

This patch adds support for the hardware feature Media Auto Sense. This feature requires a custom EEPROM image provided by our customer support team. The feature allows hardware designed with dual PHY's, fiber and copper to be used with either media without additional EEPROM changes. Fiber is preferred and driver will swap and configure for fiber media if sensed by the device at any time. Device will swap back to copper if it is the only media detected. Signed-off-by:
