Pablo Neira Ayuso says: ==================== The following patchset contains Netfilter/IPVS updates for your net-next tree, they are: * Better performance in nfnetlink_queue by avoiding copy from the packet to netlink message, from Eric Dumazet. * Remove unnecessary locking in the exit path of ebt_ulog, from Gao Feng. * Use new function ipv6_iface_scope_id in nf_ct_ipv6, from Hannes Frederic Sowa. * A couple of sparse fixes for IPVS, from Julian Anastasov. * Use xor hashing in nfnetlink_queue, as suggested by Eric Dumazet, from myself. * Allow to dump expectations per master conntrack via ctnetlink, from myself. * A couple of cleanups to use PTR_RET in module init path, from Silviu-Mihai Popescu. * Remove nf_conntrack module a bit faster if netns are in use, from Vladimir Davydov. * Use checksum_partial in ip6t_NPT, from YOSHIFUJI Hideaki. * Sparse fix for nf_conntrack, from Stephen Hemminger. ==================== Signed-off-by: David S.

Merge tag 'firewire-net-resource-mgt' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394 firewire-net driver changes: - fix memory leak and kmap leak at shutdown - release IR DMA context already at ifdown rather than shutdown (many controllers have got only 4 of them, so let's not hold it longer than strictly necessary) - misc startup/shutdown changes which prepare for later addition of IPv6-over-1394 support Signed-off-by: David S.

This patch adds support for registering DSA switches using Device Tree bindings. Note that we support programming the switch routing table even though no in-tree user seems to require it.

Hello! After patch 1 got accepted to net-next I will also send a patch to netfilter-devel to make the corresponding changes to the netfilter reassembly logic. Thanks, Hannes -- >8 -- [PATCH 2/2] ipv6: implement RFC3168 5.3 (ecn protection) for ipv6 fragmentation handling This patch also ensures that INET_ECN_CE is propagated if one fragment had the codepoint set.

This patch adds a dev_addr_genid for IPv6. The goal is to use it, combined with dev_base_seq to check if a change occurs during a netlink dump. If a change is detected, the flag NLM_F_DUMP_INTR is set in the first message after the dump was interrupted. Note that only dump of unicast addresses is checked (multicast and anycast are not checked).

If a change is detected, the flag NLM_F_DUMP_INTR is set in the first message after the dump was interrupted. Note that seq and prev_seq must be reset between each family in rtnl_dump_all() because they are specific to each family.

This patch is meant to be a follow-up for a patch originally submitted under the title "ioat: Do not enable DCA if tag map is invalid". It was brought to my attention that the preferred approach for BIOS workarounds is to set the taint flag for TAINT_FIRMWARE_WORKAROUND for systems that require BIOS workarounds. This change makes it so that the DCA workarounds for broken BIOSes will now use WARN_TAINT_ONCE(1, TAINT_FIRMWARE_WORKAROUND, ...) instead of just printing a message via dev_err.

decnet is the only subsystem left that is relying on the global netlink attribute buffer rta_buf. It's horrible design and we want to get rid of it. This converts all of decnet to do implicit attribute parsing. It also gets rid of the error prone struct dn_kern_rta. Yes, the fib_magic() stuff is not pretty.

Florian Fainelli says: ==================== This patch converts the mv643xx_eth driver to use the mvmdio MDIO bus driver instead of rolling its own implementation. As a result, all users of this mv643xx_eth driver are converted to register an "orion-mdio" platform_device. The mvmdio driver is also updated to support an interrupt line which reports SMI error/completion, and to allow traditionnal platform device registration instead of just device tree. David, I think it makes sense for you to merge all of this, since we do not want the architecture files to be desynchronized from the mv643xx_eth to avoid runtime breakage. The potential for merge conflicts should be very small. ==================== Tested-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Tested-by: Jason Cooper <jason@lakedaemon.net> Acked-by: Jason Cooper <jason@lakedaemon.net> Signed-off-by: David S.

This patch converts the Marvell MV643XX ethernet driver to use the Marvell Orion MDIO driver. As a result, PowerPC and ARM platforms registering the Marvell MV643XX ethernet driver are also updated to register a Marvell Orion MDIO driver. This driver voluntarily overlaps with the Marvell Ethernet shared registers because it will use a subset of this shared register (shared_base + 0x4 to shared_base + 0x84). The Ethernet driver is also updated to look up for a PHY device using the Orion MDIO bus driver. For ARM and PowerPC we register a single instance of the "mvmdio" driver in the system like it used to be done with the use of the "shared_smi" platform_data cookie on ARM. Note that it is safe to register the mvmdio driver only for the "ge00" instance of the driver because this "ge00" interface is guaranteed to always be explicitely registered by consumers of arch/arm/plat-orion/common.c and other instances (ge01, ge10 and ge11) were all pointing their shared_smi to ge00. For PowerPC the in-tree Device Tree Source files mention only one MV643XX ethernet MAC instance so the MDIO bus driver is registered only when id == 0.

This patch enhances the "mvmdio" to support a SMI error/done interrupt line which can be used along with a wait queue instead of doing busy-waiting on the registers.

This patch changes the mvmdio driver not to use device tree helper functions such as of_mdiobus_register() and of_iomap() so we can instantiate this driver using a classic platform_device approach. Use the device manager helper to ioremap() the base register cookie so we get automatic freeing upon error and removal. This change is harmless for Device Tree platforms because they will get the driver be registered the same way as it was before.

Switch the driver to the managed device API by replacing ioremap() calls with devm_ioremap_resource() (that will also result in calling request_mem_region() which the driver forgot to do until now) and k[mz]alloc() with devm_kzalloc() -- this permits to simplify driver's probe()/remove() method cleanup. We can now remove the ioremap() error messages since the error messages are printed by devm_ioremap_resource() itself. We can also remove the 'bitbang' field from 'struct sh_eth_private' as we don't need it anymore in order to free the memory behind it...
