2015-08-13net: Add inet_addr lookup by tableDavid Ahern
Currently inet_addr_type and inet_dev_addr_type expect local addresses to be in the local table. With the VRF device local routes for devices associated with a VRF will be in the table associated with the VRF. Provide an alternate inet_addr lookup to use a specific table rather than defaulting to the local table.

2015-08-13net: Use VRF device index for lookups on TXDavid Ahern
As with ingress use the index of VRF master device for route lookups on egress. However, the oif should only be used to direct the lookups to a specific table. Routes in the table are not based on the VRF device but rather interfaces that are part of the VRF so do not consider the oif for lookups within the table. The FLOWI_FLAG_VRFSRC is used to control this latter part. Signed-off-by: Shrijeet Mukherjee <shm@cumulusnetworks.com> Signed-off-by: David Ahern <dsa@cumulusnetworks.com> Signed-off-by: David S.

2015-08-13Merge branch 'mv88e6xxx-hw-vlan'David S. Miller
Vivien Didelot says: ==================== net: dsa: mv88e6xxx: add hardware VLAN support This patchset brings support to access hardware VLAN entries in DSA and mv88e6xxx, through switchdev VLAN objects. In the following example, ports swp[0-2] belong to bridge br0, and ports swp[3-4] belong to bridge br1. Here's an example of what can be achieved after this patchset: # bridge vlan add dev swp1 vid 100 master # bridge vlan add dev swp2 vid 100 master # bridge vlan add dev swp3 vid 100 master # bridge vlan add dev swp4 vid 100 master # bridge vlan del dev swp1 vid 100 master The above commands correctly programmed hardware VLAN 100 for port swp2, while ports swp3 and swp4 use software VLAN 100, as shown with: # bridge vlan port vlan ids swp0 None swp0 swp1 None swp1 swp2 100 swp2 100 swp3 100 swp3 swp4 100 swp4 br0 None br1 None Assuming that port 5 is the CPU port, the hardware VLAN table would contain the following data: VID FID SID 0 1 2 3 4 5 6 100 8 0 x x t x x t x Where 'x' means excluded, and 't' means tagged. Also, adding an FDB entry to VLAN 100 for port swp2 like this: # bridge fdb add 3c:97:0e:11:6e:30 dev swp2 vlan 100 Would result in the following example output: # bridge fdb # 01:00:5e:00:00:01 dev eth0 self permanent # 01:00:5e:00:00:01 dev eth1 self permanent # 00:50:d2:10:78:15 dev swp0 master br0 permanent # 00:50:d2:10:78:15 dev swp2 vlan 100 master br0 permanent # 3c:97:0e:11:6e:30 dev swp2 vlan 100 self static # 00:50:d2:10:78:15 dev swp3 master br1 permanent # 00:50:d2:10:78:15 dev swp3 vlan 100 master br1 permanent And the Address Translation Unit would contain: DB T/P Vec State Addr 008 Port 004 e 3c:97:0e:11:6e:30 ==================== Signed-off-by: David S.

2015-08-13net: ipv6 sysctl option to ignore routes when nexthop link is downAndy Gospodarek
Like the ipv4 patch with a similar title, this adds a sysctl to allow the user to change routing behavior based on whether or not the interface associated with the nexthop was an up or down link. The default setting preserves the current behavior, but anyone that enables it will notice that nexthops on down interfaces will no longer be selected: net.ipv6.conf.all.ignore_routes_with_linkdown = 0 net.ipv6.conf.default.ignore_routes_with_linkdown = 0 net.ipv6.conf.lo.ignore_routes_with_linkdown = 0 ... When the above sysctls are set, not only will link status be reported to userspace, but an indication that a nexthop is dead and will not be used is also reported. 1000::/8 via 7000::2 dev p7p1 metric 1024 dead linkdown pref medium 1000::/8 via 8000::2 dev p8p1 metric 1024 pref medium 7000::/8 dev p7p1 proto kernel metric 256 dead linkdown pref medium 8000::/8 dev p8p1 proto kernel metric 256 pref medium 9000::/8 via 8000::2 dev p8p1 metric 2048 pref medium 9000::/8 via 7000::2 dev p7p1 metric 1024 dead linkdown pref medium fe80::/64 dev p7p1 proto kernel metric 256 dead linkdown pref medium fe80::/64 dev p8p1 proto kernel metric 256 pref medium This also adds devconf support and notification when sysctl values change. v2: drop use of rt6i_nhflags since it is not needed right now Signed-off-by: Andy Gospodarek <gospo@cumulusnetworks.com> Signed-off-by: Dinesh Dutt <ddutt@cumulusnetworks.com> Signed-off-by: David S.

2015-08-13rocker: hook ndo_neigh_destroy to cleanup neigh refs in driverScott Feldman
Rocker driver tracks arp_tbl neighs to resolve IPv4 route nexthops. The driver uses NETEVENT_NEIGH_UPDATE for neigh adds and updates, but there is no event when the neigh is removed from the device (such as when the device goes admin down). This patches hooks ndo_neigh_destroy so the driver can know when a neigh is removed from the device. In response, the driver will purge the neigh entry from its internal tbl. I didn't find an in-tree users of ndo_neigh_destroy, so I'm not sure if this ndo is vestigial or if there are out-of-tree users. In any case, it does what I need here. An alternative design would be to generate NETEVENT_NEIGH_UPDATE event when neigh is being destroyed, setting state to NUD_NONE so driver knows neigh entry is dead.

Jeremy Linton says: ==================== Enable smsc911x for use with ACPI This set of patches enables the front Ethernet port on the ARM Juno development platform when used with an ACPI enabled kernel. These patches covert the of_property* calls in the driver to the DT/ACPI agnostic device_property* calls, and add the arm hardware id to the acpi_match_table. To support the above changes I copied a couple routines from of_net into the properties.c file, and modified them to be ACPI/DT agnostic. I'm not 100% sure this is the correct location for these functions. But I think they are required to avoid having a dozen different implementations scattered across assorted Ethernet adapters that are being enabled to use ACPI properties. ==================== Signed-off-by: David S.

2015-08-13drivers: net: cpsw: add am335x errata workarround for interrutpsMugunthan V N
As per Am335x Errata [1] Advisory 1.0.9, The CPSW C0_TX_PEND and C0_RX_PEND interrupt outputs provide a single transmit interrupt that combines transmit channel interrupts TXPEND[7:0] and a single receive interrupt that combines receive channel interrupts RXPEND[7:0]. The TXPEND[0] and RXPEND[0] interrupt outputs are connected to the ARM Cortex-A8 interrupt controller (INTC) rather than the C0_TX_PEND and C0_RX_PEND interrupt outputs. So even though CPSW interrupt is cleared by writing appropriate values to EOI register the interrupt is not cleared in IRQ controller. So interrupt is still pending and CPU is struck in ISR, the workaround is to disable the interrupts in ARM irq controller.

2015-08-12cxgb4: Differentiate between stids between server and filter regionHariprasad Shenai
For T4 adapter, offloaded servers tid for IPv4 connections are allocated from filter region. So add a new field for server filter tid if server tid is allocated from filter region. Signed-off-by: Hariprasad Shenai <hariprasad@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2015-08-12net: ipv4: increase dhcp inter device timeoutMugunthan V N
When a system has multiple ethernet devices and during DHCP request (for using NFS), the system waits only for HZ/2 which is 500mS before switching to another interface for DHCP. There are some routers (Ex: Trendnet routers) which responds to DHCP request at about 560mS. When the system has only one ethernet interface there is no issue as the timeout is 2S and the dev xid doesn't changes and only retries. But when the system has multiple Ethernet like DRA74x with CPSW in dual EMAC mode, the DHCP response is dropped as the dev xid changes while shifting to the next device. So changing inter device timeout to HZ (which is 1S). Signed-off-by: Mugunthan V N <mugunthanvnm@ti.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-08-12bpf: fix build warnings and add function read_trace_pipe()Kaixu Xia
There are two improvements in this patch: 1. Fix the build warnings; 2. Add function read_trace_pipe() to print the result on the screen; Before this patch, we can get the result through /sys/kernel/de bug/tracing/trace_pipe and get nothing on the screen. By applying this patch, the result can be printed on the screen. $ ./tracex6 ... tracex6-705 [003] d..1 131.428593: : CPU-3 19981414 sshd-683 [000] d..1 131.428727: : CPU-0 221682321 sshd-683 [000] d..1 131.428821: : CPU-0 221808766 sshd-683 [000] d..1 131.428950: : CPU-0 221982984 sshd-683 [000] d..1 131.429045: : CPU-0 222111851 tracex6-705 [003] d..1 131.429168: : CPU-3 20757551 sshd-683 [000] d..1 131.429170: : CPU-0 222281240 sshd-683 [000] d..1 131.429261: : CPU-0 222403340 sshd-683 [000] d..1 131.429378: : CPU-0 222561024 ...
