Some boards require custom PHY configuration, for example due to trace length differences. Add the ability to configure these registers in order to get the PHY to function on boards that need it. Because PHYs are auto-detected based on MDIO device IDs, allow PHY configuration to be specified in the parent Ethernet device node if no PHY device node is present. Signed-off-by:

For the functions mld_gq_start_timer(), mld_ifc_start_timer(), and mld_dad_start_timer(), rather use unsigned long than int as we operate only on unsigned values anyway. This seems more appropriate as there is no good reason to do type conversions to int, that could lead to future errors. Signed-off-by:

Use proper API functions to calculate jiffies from milliseconds and not the crude method of dividing HZ by a value. This ensures more accurate values even in the case of strange HZ values. While at it, also simplify code in the mlh2 case by using max(). Signed-off-by:

Some phy's can be configured to enable wake on lan (e.g. at803x or marvell 88E1318S). There is no way how to enable wol on CPSW with such connected phys. This patch adds this support. It is provided by calling the phy's related code. Tested on board with at8030x connected phy. Wol interrupt line is connected to GPIO0 on am335x. Signed-off-by:

When an Xin6 tunnel is set up, we check other netdevices to inherit the link- local address. If none is available, the interface will not have any link-local address. RFC4862 expects that each interface has a link local address. Now than this kind of tunnels supports x-netns, it's easy to fall in this case (by creating the tunnel in a netns where ethernet interfaces stand and then moving it to a other netns where no ethernet interface is available). RFC4291, Appendix A suggests two methods: the first is the one currently implemented, the second is to generate a unique identifier, so that we can always generate the link-local address. Let's use eth_random_addr() to generate this interface indentifier. I remove completly the previous method, hence for the whole life of the interface, the link-local address remains the same (previously, it depends on which ethernet interfaces were up when the tunnel interface was set up).

Use devm_ioremap_resource instead of devm_request_and_ioremap. This was done using the semantic patch scripts/coccinelle/api/devm_ioremap_resource.cocci The relevant call to platform_get_resource was manually moved down to the call to devm_ioremap_resource. Signed-off-by:

Now that the 'register_type' field of the 'sh_eth' driver's platform data is not used by the driver anymore, it's time to remove it and its initializers from the SH platform code. Also move *enum* declaring values for this field from <linux/sh_eth.h> to the local driver's header file as they're only needed by the driver itself now... Signed-off-by:

The register layout is a SoC characteristic, so it's wrong that it's stored in the otherwise board specific platform data. Add 'register_type' field to 'struct sh_eth_cpu_data', initialize it properly for each SoC, and read it from this structure instead of the platfrom data from now on... Signed-off-by:

The Ether platform data is behind the declaration of 'struct sh_eth_plat_data' as it's lacking the initializers for the 'register_type' and 'phy_interface' fields -- it means they'll be implicitly and wrongly set to SH_ETH_REG_GIGABIT and PHY_INTERFACE_MODE_NA.

The 'sh_eth' driver's probe will crash as the platform code is hopelessly behind the platform data -- it passes PHY ID instead of 'struct sh_eth_plat_data *'. Strangely, both commit d88a3ea6 (SH7619 add ethernet controler support) that added the platform code and commit 71557a37 ([netdrvr] sh_eth: Add SH7619 support) were done in about the same time, yet the latter one added 'struct sh_eth_plat_data' and the platform code didn't ever get updated...

Add the ndo_busy_poll handler. Use skb_mark_napi_id to mark receive packets with the napi id. For each slice, use per-slice spinlock and state variable to ensure that only one handler processes receive pacekts. Locking, statistics counters, and the ndo_busy_poll handler follow those in the ixgbe driver. So, credit goes to that driver's authors. Signed-off-by:

As discussed last year [1], there is no compelling reason to limit IPv4 MTU to 0xFFF0, while real limit is 0xFFFF [1] : http://marc.info/?l=linux-netdev&m=135607247609434&w=2 Willem raised this issue again because some of our internal regression tests broke after lo mtu being set to 65536. IP_MTU reports 0xFFF0, and the test attempts to send a RAW datagram of mtu + 1 bytes, expecting the send() to fail, but it does not. Alexey raised interesting points about TCP MSS, that should be addressed in follow-up patches in TCP stack if needed, as someone could also set an odd mtu anyway. Signed-off-by:

When attempting to change e.g. the advertising mask when the link is down ecmd->speed is -1 causing mii_ethtool_sset() to bail out. This bug bit when connecting to a gigabit switch through a 4-pin (industrial) cable, since link negotiation would not complete (both endpoints claimed to be gigabit-capable, but this is not possible with only 4 pins). Any attempt to fix this by setting autonegation to not offer 1000Mbps failed as the setting would not be accepted while the link was still down... Set ecmd->speed to SPEED_1000 to satisfy mii_ethtool_sset() (the actual value of ecmd->speed doesn't matter as long as it is valid, since a re-negotation is forced afterwards). Signed-off-by:

Conflicts: net/netfilter/nf_conntrack_proto_tcp.c The conflict had to do with overlapping changes dealing with fixing the use of an "s32" to hold the value returned by NAT_OFFSET(). Pablo Neira Ayuso says: ==================== The following batch contains Netfilter/IPVS updates for your net-next tree. More specifically, they are: * Trivial typo fix in xt_addrtype, from Phil Oester. * Remove net_ratelimit in the conntrack logging for consistency with other logging subsystem, from Patrick McHardy. * Remove unneeded includes from the recently added xt_connlabel support, from Florian Westphal. * Allow to update conntracks via nfqueue, don't need NFQA_CFG_F_CONNTRACK for this, from Florian Westphal. * Remove tproxy core, now that we have socket early demux, from Florian Westphal. * A couple of patches to refactor conntrack event reporting to save a good bunch of lines, from Florian Westphal. * Fix missing locking in NAT sequence adjustment, it did not manifested in any known bug so far, from Patrick McHardy. * Change sequence number adjustment variable to 32 bits, to delay the possible early overflow in long standing connections, also from Patrick. * Comestic cleanups for IPVS, from Dragos Foianu. * Fix possible null dereference in IPVS in the SH scheduler, from Daniel Borkmann. * Allow to attach conntrack expectations via nfqueue. Before this patch, you had to use ctnetlink instead, thus, we save the conntrack lookup. * Export xt_rpfilter and xt_HMARK header files, from Nicolas Dichtel. ==================== Signed-off-by: -

Alexander Aring says: ==================== 6lowpan: address uncompression fixes The current implementation to uncompress addresses in a 6lowpan header is completely broken. This patch series fixes the parsing of addresses in a 6lowpan header. It contains a major rewrite of the uncompress address function to parse the address in a correct way. Tested with the ravenusbstick(contiki 6LoWPAN stack) and beaglebone (linux 6LoWPAN Stack) on the other side. The linux side contains all possible addresses for the uncompression cases. Then I type a ping6 for each case and lookup in wireshark and dmesg the correct reconstruction. ==================== Signed-off-by: -

This patch drops the pre and postcount calculation from the lowpan_uncompress_addr function.We use instead a switch/case over address_mode value. The original implementation has several bugs in this function and it was hard to decrypt how it works. To make it maintainable and fix these bugs this patch basically reimplements lowpan_uncompress_addr from scratch. A list of bugs we found in the current implementation: 1) Properly support uncompression of short-address based IPv6 addresses (instead of basically copying garbage) 2) Fix use and uncompression of long-addresses based IPv6 addresses 3) Add missing ff:fe00 in the case of SAM/DAM = 2 and M = 0 Signed-off-by:
