2018-01-02net: phy: marvell10g: add support for half duplex 100M and 10MRussell King
Add support for half-duplex 100M and 10M copper connections by parsing the advertisment results rather than trying to decode the negotiated speed from one of the PHYs "vendor" registers. This allows us to decode the duplex as well, which means we can support half-duplex mode for the slower speeds.

2018-01-02inet_diag: Add equal-operator for portsKristian Evensen
inet_diag currently provides less/greater than or equal operators for comparing ports when filtering sockets. An equal comparison can be performed by combining the two existing operators, or a user can for example request a port range and then do the final filtering in userspace. However, these approaches both have drawbacks. Implementing equal using LE/GE causes the size and complexity of a filter to grow quickly as the number of ports increase, while it on busy machines would be great if the kernel only returns information about relevant sockets. This patch introduces source and destination port equal operators. INET_DIAG_BC_S_EQ is used to match a source port, INET_DIAG_BC_D_EQ a destination port, and usage is the same as for the existing port operators. I.e., the port to match is stored in the no-member of the next inet_diag_bc_op-struct in the filter. Signed-off-by: Kristian Evensen <kristian.evensen@gmail.com> Signed-off-by: David S.

2018-01-02sfp: fix sfp-bus oops when removing socket/upstreamRussell King
When we remove a socket or upstream, and the other side isn't registered, we dereference a NULL pointer, causing a kernel oops. Fix this.

2018-01-02macvlan: Fix one possible double freeGao Feng
Because the macvlan_uninit would free the macvlan port, so there is one double free case in macvlan_common_newlink. When the macvlan port is just created, then register_netdevice or netdev_upper_dev_link failed and they would invoke macvlan_uninit. Then it would reach the macvlan_port_destroy which triggers the double free. Signed-off-by: Gao Feng <gfree.wind@vip.163.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2018-01-02selftests/net: fix bugs in address and port initializationSowmini Varadhan
Address/port initialization should work correctly regardless of the order in which command line arguments are supplied, E.g, cfg_port should be used to connect to the remote host even if it is processed after -D, src/dst address initialization should not require that [-4|-6] be specified before the -S or -D args, receiver should be able to bind to *.<cfg_port> Achieve this by making sure that the address/port structures are initialized after all command line options are parsed. Store cfg_port in host-byte order, and use htons() to set up the sin_port/sin6_port before bind/connect, so that the network system calls get the correct values in network-byte order.

2018-01-02net_sch: red: Fix the new offload indicationNogah Frankel
Update the offload flag, TCQ_F_OFFLOADED, in each dump call (and ignore the offloading function return value in relation to this flag). This is done because a qdisc is being initialized, and therefore offloaded before being grafted. Since the ability of the driver to offload the qdisc depends on its location, a qdisc can be offloaded and un-offloaded by graft calls, that doesn't effect the qdisc itself.
