2014-11-26tipc: remove node subscription infrastructureYing Xue9-179/+56
The node subscribe infrastructure represents a virtual base class, so its users, such as struct tipc_port and struct publication, can derive its implemented functionalities. However, after the removal of struct tipc_port, struct publication is left as its only single user now. So defining an abstract infrastructure for one user becomes no longer reasonable. If corresponding new functions associated with the infrastructure are moved to name_table.c file, the node subscription infrastructure can be removed as well.

2014-11-26ipv6: Remove unnecessary testzhuyj1-4/+2
The "init_net" test in function addrconf_exit_net is introduced in commit 44a6bd29 [Create ipv6 devconf-s for namespaces] to avoid freeing init_net. In commit c900a800 [ipv6: fix bad free of addrconf_init_net], function addrconf_init_net will allocate memory for every net regardless of init_net. In this case, it is unnecessary to make "init_net" test.

2014-11-26net: Add remcsum_adjust as common function for remote checksum offloadTom Herbert1-0/+16
This function does the work to update a checksum field as part of remote checksum offload. remcsum_adjust does the following: 1) Subtract out the calculated checksum from the beginning of the packet (ptr arg) to the start offset. 2) Adjust the checksum field indicated by offset based on the modified checksum value from above step. 3) Return the difference in the old checksum field value and the new one. The caller will use this to update skb->csum and NAPI csum. Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-11-26pkt_sched: fq: increase max delay from 125 ms to one secondEric Dumazet1-5/+4
FQ/pacing has a clamp of delay of 125 ms, to avoid some possible harm. It turns out this delay is too small to allow pacing low rates : Some ISP setup very aggressive policers as low as 16kbit. Now TCP stack has spurious rtx prevention, it seems safe to increase this fixed parameter, without adding a qdisc attribute.

2014-11-26net/mlx4_core: Limit count field to 24 bits in qp_alloc_resJack Morgenstein1-1/+1
Some VF drivers use the upper byte of "param1" (the qp count field) in mlx4_qp_reserve_range() to pass flags which are used to optimize the range allocation. Under the current code, if any of these flags are set, the 32-bit count field yields a count greater than 2^24, which is out of range, and this VF fails. As these flags represent a "best-effort" allocation hint anyway, they may safely be ignored. Therefore, the PF driver may simply mask out the bits.

2014-11-26kvm: fix kvm_is_mmio_pfn() and rename to kvm_is_reserved_pfn()Ard Biesheuvel4-13/+13
This reverts commit 85c8555ff0 ("KVM: check for !is_zero_pfn() in kvm_is_mmio_pfn()") and renames the function to kvm_is_reserved_pfn. The problem being addressed by the patch above was that some ARM code based the memory mapping attributes of a pfn on the return value of kvm_is_mmio_pfn(), whose name indeed suggests that such pfns should be mapped as device memory. However, kvm_is_mmio_pfn() doesn't do quite what it says on the tin, and the existing non-ARM users were already using it in a way which suggests that its name should probably have been 'kvm_is_reserved_pfn' from the beginning, e.g., whether or not to call get_page/put_page on it etc. This means that returning false for the zero page is a mistake and the patch above should be reverted.

2014-11-26arm64: KVM: Handle traps of ICC_SRE_EL1 as RAZ/WIChristoffer Dall1-0/+9
When running on a system with a GICv3, we currenly don't allow the guest to access the system register interface of the GICv3. We do this by clearing the ICC_SRE_EL2.Enable, which causes all guest accesses to ICC_SRE_EL1 to trap to EL2 and causes all guest accesses to other ICC_ registers to cause an undefined exception in the guest. However, we currently don't handle the trap of guest accesses to ICC_SRE_EL1 and will spill out a warning. The trap just needs to handle the access as RAZ/WI, and a guest that tries to prod this register and set ICC_SRE_EL1.SRE=1, must read back the value (which Linux already does) to see if it succeeded, and will thus observe that ICC_SRE_EL1.SRE was not set. Add the simple trap handler in the sorted table of the system registers.

2014-11-26arm64: KVM: fix unmapping with 48-bit VAsMark Rutland1-1/+2
Currently if using a 48-bit VA, tearing down the hyp page tables (which can happen in the absence of a GICH or GICV resource) results in the rather nasty splat below, evidently becasue we access a table that doesn't actually exist. Commit 38f791a4e499792e (arm64: KVM: Implement 48 VA support for KVM EL2 and Stage-2) added a pgd_none check to __create_hyp_mappings to account for the additional level of tables, but didn't add a corresponding check to unmap_range, and this seems to be the source of the problem. This patch adds the missing pgd_none check, ensuring we don't try to access tables that don't exist.

2014-11-25Revert "netfilter: conntrack: fix race in __nf_conntrack_confirm against get_next_corpse"Pablo Neira1-8/+6
This reverts commit 5195c14c8b27cc0b18220ddbf0e5ad3328a04187. If the conntrack clashes with an existing one, it is left out of the unconfirmed list, thus, crashing when dropping the packet and releasing the conntrack since golden rule is that conntracks are always placed in any of the existing lists for traceability reasons.

2014-11-25vxlan: Fix boolean flip in VXLAN_F_UDP_ZERO_CSUM6_[TX|RX]Alexander Duyck1-2/+2
In "vxlan: Call udp_sock_create" there was a logic error that resulted in the default for IPv6 VXLAN tunnels going from using checksums to not using checksums. Since there is currently no support in iproute2 for setting these values it means that a kernel after the change cannot talk over a IPv6 VXLAN tunnel to a kernel prior the change.

2014-11-25ip6_udp_tunnel: Fix checksum calculationAlexander Duyck1-3/+1
The UDP checksum calculation for VXLAN tunnels is currently using the socket addresses instead of the actual packet source and destination addresses. As a result the checksum calculated is incorrect in some cases. Also uh->check was being set twice, first it was set to 0, and then it is set again in udp6_set_csum. This change removes the redundant assignment to 0. Fixes: acbf74a7 ("vxlan: Refactor vxlan driver to make use of the common UDP tunnel functions.")

The xpad wireless endpoint is not a bulk endpoint on my devices, but rather an interrupt one, so the USB core complains when it is submitted. I'm guessing that the author really did mean that this should be an interrupt urb, but as there are a zillion different xpad devices out there, let's cover out bases and handle both bulk and interrupt endpoints just as easily.

2014-11-24net/ping: handle protocol mismatching scenarioJane Zhou1-0/+2
ping_lookup() may return a wrong sock if sk_buff's and sock's protocols dont' match. For example, sk_buff's protocol is ETH_P_IPV6, but sock's sk_family is AF_INET, in that case, if sk->sk_bound_dev_if is zero, a wrong sock will be returned. the fix is to "continue" the searching, if no matching, return NULL.

2014-11-24net/smsc911x: Add minimal runtime PM supportGeert Uytterhoeven1-0/+10
Add minimal runtime PM support (enable on probe, disable on remove), to ensure proper operation with a parent device that uses runtime PM. This is needed on systems where the external bus controller module of the SoC is contained in a PM domain and/or has a gateable functional clock. In such cases, before accessing any device connected to the external bus, the PM domain must be powered up, and/or the functional clock must be enabled, which is typically handled through runtime PM by the bus controller driver. An example of this is the kzm9g development board, where an smsc9220 Ethernet controller is connected to the Bus State Controller (BSC) of a Renesas sh73a0 SoC.

2014-11-24ipvlan: Initial check-in of the IPVLAN driver.Mahesh Bandewar9-0/+1678
This driver is very similar to the macvlan driver except that it uses L3 on the frame to determine the logical interface while functioning as packet dispatcher. It inherits L2 of the master device hence the packets on wire will have the same L2 for all the packets originating from all virtual devices off of the same master device. This driver was developed keeping the namespace use-case in mind. Hence most of the examples given here take that as the base setup where main-device belongs to the default-ns and virtual devices are assigned to the additional namespaces. The device operates in two different modes and the difference in these two modes in primarily in the TX side. (a) L2 mode : In this mode, the device behaves as a L2 device. TX processing upto L2 happens on the stack of the virtual device associated with (namespace). Packets are switched after that into the main device (default-ns) and queued for xmit. RX processing is simple and all multicast, broadcast (if applicable), and unicast belonging to the address(es) are delivered to the virtual devices. (b) L3 mode : In this mode, the device behaves like a L3 device. TX processing upto L3 happens on the stack of the virtual device associated with (namespace). Packets are switched to the main-device (default-ns) for the L2 processing. Hence the routing table of the default-ns will be used in this mode. RX processins is somewhat similar to the L2 mode except that in this mode only Unicast packets are delivered to the virtual device while main-dev will handle all other packets. The devices can be added using the "ip" command from the iproute2 package - ip link add link <master> <virtual> type ipvlan mode [ l2 | l3 ] Signed-off-by: Mahesh Bandewar <maheshb@google.com> Cc: Eric Dumazet <edumazet@google.com> Cc: Maciej Żenczykowski <maze@google.com> Cc: Laurent Chavey <chavey@google.com> Cc: Tim Hockin <thockin@google.com> Cc: Brandon Philips <brandon.philips@coreos.com> Cc: Pavel Emelianov <xemul@parallels.com> Signed-off-by: David S.
