2015-09-03sctp: add routing output fallbackMarcelo Ricardo Leitner1-1/+7
Commit 0ca50d12fe46 added a restriction that the address must belong to the output interface, so that sctp will use the right interface even when using secondary addresses. But it breaks IPVS setups, on which people is used to attach VIP addresses to loopback interface on real servers. It's preferred to attach to the interface actually in use, but it's a very common setup and that used to work. This patch then saves the first routing good result, even if it would be going out through an interface that doesn't have that address. If no better hit found, it's then used. This effectively restores the original behavior if no better interface could be found.

Therefore, split the more generic parts into a common header under include/linux/netfilter/ and move nf_ct_zone_dflt into the built-in section that already holds parts related to CONFIG_NF_CONNTRACK in the netfilter core.

2015-09-02net: fec: clear receive interrupts before processing a packetRussell King1-0/+1
The patch just to re-submit the patch "db3421c114cfa6326" because the patch "4d494cdc92b3b9a0" remove the change. Clear any pending receive interrupt before we process a pending packet. This helps to avoid any spurious interrupts being raised after we have fully cleaned the receive ring, while still allowing an interrupt to be raised if we receive another packet. The position of this is critical: we must do this prior to reading the next packet status to avoid potentially dropping an interrupt when a packet is still pending.

2015-09-02xen-netback: add support for multicast controlPaul Durrant5-1/+144
Xen's PV network protocol includes messages to add/remove ethernet multicast addresses to/from a filter list in the backend. This allows the frontend to request the backend only forward multicast packets which are of interest thus preventing unnecessary noise on the shared ring. The canonical netif header in git://xenbits.xen.org/xen.git specifies the message format (two more XEN_NETIF_EXTRA_TYPEs) so the minimal necessary changes have been pulled into include/xen/interface/io/netif.h. To prevent the frontend from extending the multicast filter list arbitrarily a limit (XEN_NETBK_MCAST_MAX) has been set to 64 entries. This limit is not specified by the protocol and so may change in future. If the limit is reached then the next XEN_NETIF_EXTRA_TYPE_MCAST_ADD sent by the frontend will be failed with NETIF_RSP_ERROR.

2015-09-02sock, diag: fix panic in sock_diag_put_filterinfoDaniel Borkmann1-0/+3
diag socket's sock_diag_put_filterinfo() dumps classic BPF programs upon request to user space (ss -0 -b). However, native eBPF programs attached to sockets (SO_ATTACH_BPF) cannot be dumped with this method: Their orig_prog is always NULL. However, sock_diag_put_filterinfo() unconditionally tries to access its filter length resp. wants to copy the filter insns from there. Internal cBPF to eBPF transformations attached to sockets don't have this issue, as orig_prog state is kept. It's currently only used by packet sockets. If we would want to add native eBPF support in the future, this needs to be done through a different attribute than PACKET_DIAG_FILTER to not confuse possible user space disassemblers that work on diag data.

2015-09-01ixgbe: Remove bimodal SR-IOV disablingAlex Williamson1-6/+1
When unbinding an SR-IOV device with VFs configured from ixgbe, the driver behaves in one of two ways. If max_vfs was specified, the SR-IOV state is disabled, removing the VFs. The occurs regardless of whether the VF count was later modified through sysfs. If however max_vfs is zero, such as by not specifying the module parameter, the VFs persist after the PF is unbound from ixgbe. If the PF is then bound to vfio-pci to be assigned to a VM, the PF is non-functional. >From the comment, commit da36b64736cf ("ixgbe: Implement PCI SR-IOV sysfs callback operation") clearly intended this alternate behavior, but probably didn't realize the PF doesn't work in this mode. This bimodal behavior is confusing to users and results in a state where the PF is broken for other uses unless the user sets sriov_numvfs to zero prior to unbinding the device. Remove this behavior so that VFs are removed and the PF is functional for other uses after unbind, regardless of the way VFs are enabled.

This patch removes the redundant lan_id in the phy struct and uses the bus version. Both variables exist and intend to represent the STATUS register LAN_ID field. However, phy.lan_id is not bit shifted so the phy.lan_id = 0x0 for LAN Id 0 and phy.lan_id = 0x4 for LAN Id 1. Where bus.lan_id is bit shifted so bus.lan_id = 0x0 for LAN Id 0 and bus.lan_id = 0x1 for LAN Id 1. There seems no need for the additional lan_id variable and this should make the code less confusing.

2015-09-01i40e: Set defport behavior for the Main VSI when in promiscuous modeAnjali Singhai Jain2-8/+30
This fixes bugs where the port is not receiving multicast or VLAN tagged packets when in promiscuous mode. This can occur when a SW bridge is created on top of the device. This also fixes issues where the promiscuous behavior setting was not being preserved across a reset caused by features being enabled or disabled. We are using defport instead of doing a true promiscuous mode because we do not need to receive the SRIOV or VMDq VSI directed traffic which would suck up bandwidth and is really not intended for the SW bridge. In addition, with defport we get VLAN promiscuous behavior which is not possible from the VSI level promiscuous setting.

2015-09-01phylib: fix device deletion order in mdiobus_unregister()Mark Salter1-1/+1
commit 8b63ec1837fa ("phylib: Make PHYs children of their MDIO bus, not the bus' parent.") uncovered a problem in mdiobus_unregister() which leads to this warning when I reboot an APM Mustang (arm64) platform: WARNING: CPU: 7 PID: 4239 at fs/sysfs/group.c:224 sysfs_remove_group+0xa0/0xa4() sysfs group fffffe0000e07a10 not found for kobject 'xgene-mii-eth0:03' ...

This wasn't a problem before because the phys were not children of the bus: /sys/devices/platform/APMC0D05:00/net/eth0/xgene-mii-eth0:03 /sys/devices/platform/APMC0D05:00/net/eth0/xgene-mii-eth0 But now that they are: /sys/devices/platform/APMC0D05:00/net/eth0/xgene-mii-eth0/xgene-mii-eth0:03 when mdiobus_unregister deletes the bus device, the phy subdirs are removed from sysfs also. So when the phys are unregistered afterward, we get the warning. This patch changes the order so that phys are unregistered before the bus device is deleted.

Wall time obtained from do_gettimeofday is susceptible to sudden jumps due to user setting the time or due to NTP. Monotonic time is constantly increasing time better suited for comparing two timestamps. Signed-off-by: Abhilash Jindal <klock.android@gmail.com> Signed-off-by: Rafael J.
