After "Cache input routes in fib_info nexthops" (commit d2d68ba9) and "Elide fib_validate_source() completely when possible" (commit 7a9bc9b8) we can not send ICMP redirects. It seems we should not cache the RTCF_DOREDIRECT flag in nh_rth_input because the same fib_info can be used for traffic that is not redirected, eg. from other input devices or from sources that are not in same subnet. As result, we have to disable the caching of RTCF_DOREDIRECT flag and to force source validation for the case when forwarding traffic to the input device. If traffic comes from directly connected source we allow redirection as it was done before both changes. Avoid setting RTCF_DOREDIRECT if IN_DEV_TX_REDIRECTS is disabled, this can avoid source address validation and to help caching the routes. After the change "Adjust semantics of rt->rt_gateway" (commit f8126f1d) we should make sure our ICMP_REDIR_HOST messages contain daddr instead of 0.0.0.0 when target is directly connected.

It seems IPV6_GRO_CB(skb)->proto can be destroyed in skb_gro_receive() if a new skb is allocated (to serve as an anchor for frag_list) We copy NAPI_GRO_CB() only (not the IPV6 specific part) in : *NAPI_GRO_CB(nskb) = *NAPI_GRO_CB(p); So we leave IPV6_GRO_CB(nskb)->proto to 0 (fresh skb allocation) instead of IPPROTO_TCP (6) ipv6_gro_complete() isnt able to call ops->gro_complete() [ tcp6_gro_complete() ] Fix this by moving proto in NAPI_GRO_CB() and getting rid of IPV6_GRO_CB Signed-off-by:

6a32e4f9 made the vlan code skip marking vlan-tagged frames for not locally configured vlans as PACKET_OTHERHOST if there was an rx_handler, as the rx_handler could cause the frame to be received on a different (virtual) vlan-capable interface where that vlan might be configured. As rx_handlers do not necessarily return RX_HANDLER_ANOTHER, this could cause frames for unknown vlans to be delivered to the protocol stack as if they had been received untagged. For example, if an ipv6 router advertisement that's tagged for a locally not configured vlan is received on an interface with macvlan interfaces attached, macvlan's rx_handler returns RX_HANDLER_PASS after delivering the frame to the macvlan interfaces, which caused it to be passed to the protocol stack, leading to ipv6 addresses for the announced prefix being configured even though those are completely unusable on the underlying interface. The fix moves marking as PACKET_OTHERHOST after the rx_handler so the rx_handler, if there is one, sees the frame unchanged, but afterwards, before the frame is delivered to the protocol stack, it gets marked whether there is an rx_handler or not.

Current GRO can hold packets in gro_list for almost unlimited time, in case napi->poll() handler consumes its budget over and over. In this case, napi_complete()/napi_gro_flush() are not called. Another problem is that gro_list is flushed in non friendly way : We scan the list and complete packets in the reverse order. (youngest packets first, oldest packets last) This defeats priorities that sender could have cooked. Since GRO currently only store TCP packets, we dont really notice the bug because of retransmits, but this behavior can add unexpected latencies, particularly on mice flows clamped by elephant flows. This patch makes sure no packet can stay more than 1 ms in queue, and only in stress situations. It also complete packets in the right order to minimize latencies. Signed-off-by:

Marvell 88E8001 on an ASUS P5NSLI motherboard is unable to send/receive packets on a system with >4gb ram unless a 32bit DMA mask is used. This issue has been around for years and a fix was sent 3.5 years ago, but there was some debate as to whether it should instead be fixed as a PCI quirk. http://www.spinics.net/lists/netdev/msg88670.html However, 18 months later a similar workaround was introduced for another chipset exhibiting the same problem. http://www.spinics.net/lists/netdev/msg142287.htmlSigned-off-by:

We report cached pmtu values even if they are already expired. Change this to not report these values after they are expired and fix a race in the expire time calculation, as suggested by Eric Dumazet. Signed-off-by:

When a local tool like tracepath tries to send packets bigger than the device mtu, we create a nh exeption and set the pmtu to device mtu. The device mtu does not expire, so check if the device mtu is smaller than the reported pmtu and don't crerate a nh exeption in that case. Signed-off-by:

Steffen Klassert authored
Some protocols, like IPsec still cache routes. So we need to invalidate the old route on pmtu events to avoid the reuse of stale routes. We also need to update the mtu and expire time of the route if we already use a nh exception route, otherwise we ignore newly learned pmtu values after the first expiration. With this patch we always invalidate or update the route on pmtu events. Signed-off-by:

Before accessing skb first fragment, better make sure there is one. This is probably not needed for old kernels, since an ethernet frame cannot contain only an ethernet header, but the recent GRO addition to tunnels makes this patch needed. Also skb_gro_reset_offset() can be static, it actually allows compiler to inline it. Signed-off-by:

IPv4 side of the problem was addressed in commit a9e050f4 (net: tcp: GRO should be ECN friendly) This patch does the same, but for IPv6 : A Traffic Class mismatch doesnt mean flows are different, but instead should force a flush of previous packets. This patch removes artificial packet reordering problem. Signed-off-by:

The retry loop in neigh_resolve_output() and neigh_connected_output() call dev_hard_header() with out reseting the skb to network_header. This causes the retry to fail with skb_under_panic. The fix is to reset the network_header within the retry loop. Signed-off-by:

Over time, skb recycling infrastructure got litle interest and many bugs. Generic rx path skb allocation is now using page fragments for efficient GRO / TCP coalescing, and recyling a tx skb for rx path is not worth the pain. Last identified bug is that fat skbs can be recycled and it can endup using high order pages after few iterations. With help from Maxime Bizon, who pointed out that commit 87151b86 (net: allow pskb_expand_head() to get maximum tailroom) introduced this regression for recycled skbs. Instead of fixing this bug, lets remove skb recycling. Drivers wanting really hot skbs should use build_skb() anyway, to allocate/populate sk_buff right before netif_receive_skb() Signed-off-by:

Pull UAPI disintegration fixes from David Howells: "There are three main parts: (1) I found I needed some more fixups in the wake of testing Arm64 (some asm/unistd.h files had weird guards that caused problems - mostly in arches for which I don't have a compiler) and some __KERNEL__ splitting needed to take place in Arm64. (2) I found that c6x was missing some __KERNEL__ guards in its asm/signal.h. Mark Salter pointed me at a tree with a patch to remove that file entirely and use the asm-generic variant instead. (3) Lastly, m68k turned out to have a header installation problem due to it lacking a kvm_para.h file. The conditional installation bits for linux/kvm_para.h, linux/kvm.h and linux/a.out.h weren't very well specified - and didn't work if an arch didn't have the asm/ version of that file, but there *was* an asm-generic/ version. It seems the "ifneq $((wildcard ...),)" for each of those three headers in include/kernel/Kbuild is invoked twice during header installation, and the second time it matches on the just installed asm-generic/kvm_para.h file and thus incorrectly installs linux/kvm_para.h as well. Most arches actually have an asm/kvm_para.h, so this wasn't detectable in those." * 'uapi-prep' of git://git.infradead.org/users/dhowells/linux-headers: UAPI: Fix conditional header installation handling (notably kvm_para.h on m68k) c6x: remove c6x signal.h UAPI: Split compound conditionals containing __KERNEL__ in Arm64 UAPI: Fix the guards on various asm/unistd.h files c6x: make dsk6455 the default config -

Merge tag 'stable/for-linus-3.7-arm-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen Pull ADM Xen support from Konrad Rzeszutek Wilk: Features: * Allow a Linux guest to boot as initial domain and as normal guests on Xen on ARM (specifically ARMv7 with virtualized extensions). PV console, block and network frontend/backends are working. Bug-fixes: * Fix compile linux-next fallout. * Fix PVHVM bootup crashing. The Xen-unstable hypervisor (so will be 4.3 in a ~6 months), supports ARMv7 platforms. The goal in implementing this architecture is to exploit the hardware as much as possible. That means use as little as possible of PV operations (so no PV MMU) - and use existing PV drivers for I/Os (network, block, console, etc). This is similar to how PVHVM guests operate in X86 platform nowadays - except that on ARM there is no need for QEMU. The end result is that we share a lot of the generic Xen drivers and infrastructure. Details on how to compile/boot/etc are available at this Wiki: http://wiki.xen.org/wiki/Xen_ARMv7_with_Virtualization_Extensions and this blog has links to a technical discussion/presentations on the overall architecture: http://blog.xen.org/index.php/2012/09/21/xensummit-sessions-new-pvh-virtualisation-mode-for-arm-cortex-a15arm-servers-and-x86/ * tag 'stable/for-linus-3.7-arm-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen: (21 commits) xen/xen_initial_domain: check that xen_start_info is initialized xen: mark xen_init_IRQ __init xen/Makefile: fix dom-y build arm: introduce a DTS for Xen unprivileged virtual machines MAINTAINERS: add myself as Xen ARM maintainer xen/arm: compile netback xen/arm: compile blkfront and blkback xen/arm: implement alloc/free_xenballooned_pages with alloc_pages/kfree xen/arm: receive Xen events on ARM xen/arm: initialize grant_table on ARM xen/arm: get privilege status xen/arm: introduce CONFIG_XEN on ARM xen: do not compile manage, balloon, pci, acpi, pcpu and cpu_hotplug on ARM xen/arm: Introduce xen_ulong_t for unsigned long xen/arm: Xen detection and shared_info page mapping docs: Xen ARM DT bindings xen/arm: empty implementation of grant_table arch specific functions xen/arm: sync_bitops xen/arm: page.h definitions xen/arm: hypercalls ...

Pull powerpc updates from Benjamin Herrenschmidt: "Some highlights in addition to the usual batch of fixes: - 64TB address space support for 64-bit processes by Aneesh Kumar - Gavin Shan did a major cleanup & re-organization of our EEH support code (IBM fancy PCI error handling & recovery infrastructure) which paves the way for supporting different platform backends, along with some rework of the PCIe code for the PowerNV platform in order to remove home made resource allocations and instead use the generic code (which is possible after some small improvements to it done by Gavin). - Uprobes support by Ananth N Mavinakayanahalli - A pile of embedded updates from Freescale folks, including new SoC and board supports, more KVM stuff including preparing for 64-bit BookE KVM support, ePAPR 1.1 updates, etc..."
