2013-12-18isdn: use strlcpy() instead strcpy()Dan Carpenter
I don't think the in-kernel drivers ever hit this strcpy() so this doesn't change how the code works. But strlcpy() is safer. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2013-12-18ipv6: support IPV6_PMTU_INTERFACE on socketsHannes Frederic Sowa
IPV6_PMTU_INTERFACE is the same as IPV6_PMTU_PROBE for ipv6. Add it nontheless for symmetry with IPv4 sockets. Also drop incoming MTU information if this mode is enabled. The additional bit in ipv6_pinfo just eats in the padding behind the bitfield. There are no changes to the layout of the struct at all.

2013-12-18ipv4: new ip_no_pmtu_disc mode to always discard incoming frag needed msgsHannes Frederic Sowa
This new mode discards all incoming fragmentation-needed notifications as I guess was originally intended with this knob. To not break backward compatibility too much, I only added a special case for mode 2 in the receiving path. Signed-off-by: Hannes Frederic Sowa <hannes@stressinduktion.org> Signed-off-by: David S.

2013-12-18inet: make no_pmtu_disc per namespace and kill ipv4_configHannes Frederic Sowa
The other field in ipv4_config, log_martians, was converted to a per-interface setting, so we can just remove the whole structure. Signed-off-by: Hannes Frederic Sowa <hannes@stressinduktion.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2013-12-18Merge branch 'master' of ↵David S. Miller
git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to i40e, ixgbevf, ixgbe and igb. Don provides an ixgbevf patch to add DCB configuration into the queue setup so that we won't have to allocate queues in a separate place when enabling DCB. Guenter Roeck provides 2 patches for ixgbe to simplify the code by attaching hwmon sysfs attributes to hwmon device instead of PCI device. Also fix an issues where the temperature sensor attribute index was being started with the value 0 and not 1 as per the hwmon API. Carolyn provides igb patches to fix queue allocation method to accommodate changes during runtime. This includes changing how the driver initializes MSIx and checks for MSIx configuration to make it easier to reconfigure the device when queue changes happen at runtime. Neerav and Shannon fixes i40e debugfs commands that dump hex information by using print_hex_dump(). Shannon provides several i40e fixes which include the prevention of null pointer exception in the dump descriptor by checking that rings were allocated before trying to reference them. Fixed up a couple of scanfs to accept various base numbers instead of silently requiring hex. Anjali fixes up i40e where the incorrect defines were being used for misc interrupts. Alan Cox provides a fix for i40e where we assume that the resulting buffer is zero terminated when we then re-use it. The sscanf is limited to 512 bytes but needs to be 511 to allow for a terminator. Stephen Hemminger fixes i40e by making local functions static and removes unused code (i40e_aq_add/remove_vlan() functions). ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2013-12-17igb: Change to use statically allocated array for MSIx entriesCarolyn Wyborny
This patch changes how the driver initializes MSIx and checks for MSIx configuration.

2013-12-17igb: Fix queue allocation method to accommodate changing during runtimeCarolyn Wyborny
When changing number of queues using ethtool's set_channels during runtime, a queue allocation could fail, which can leave the device in a down state. In order to preserve the usability of the device in this scenario, this patch changes the driver to allocate the number of queues only if they have not been allocated already. The first allocation is then done for the max number of queues, which is the default queues for this driver. With this change, queue quantity changes are not subject to queue allocation failures.

2013-12-17ixgbe: Convert to use devm_hwmon_device_register_with_groupsGuenter Roeck
Simplify the code. Attach hwmon sysfs attributes to hwmon device instead of pci device. Avoid race conditions caused by attributes being created after hwmon device registration. Implicitly (through hwmon API) add mandatory 'name' sysfs attribute. 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.

Atzm Watanabe says: ==================== packet: deliver VLAN TPID to userspace This patchset enables userspace to get VLAN TPID as well as the VLAN TCI. After the 802.1AD support, userspace packet receivers (packet dumper, software switch, and the like) need how to know VLAN TPID in order to reconstruct original tagged frame. v4: Simply use sizeof(tp_padding) for zeroing the padding bytes, commented by David Laight. Use __u16 for tp_vlan_tpid in tpacket_hdr_variant1, commented by Daniel Borkmann. v3: Add a definition which indicates whether tp_vlan_tpid is valid. Explicitly define pad bytes for tpacket{2,3}_hdr and pick the area for tp_vlan_tpid from the definition.
