rtnetlink: provide api for getting and setting slave info

2014-01-23T05:57:05Z

Recent patch bonding: add netlink attributes to slave link dev (1d3ee88ae0d6) Introduced yet another device specific way to access slave information over rtnetlink. There is one already there for bridge. This patch introduces generic way to do this, for getting and setting info as well by extending link_ops. Later on, this new interface will be used for bridge ports as well. Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

netlink: cleanup rntl_af_register

2014-01-02T04:42:19Z

The function __rtnl_af_register is never called outside this code, and the return value is always 0. Signed-off-by: David S. Miller

rtnetlink.h: Remove extern from function prototypes

2013-09-23T05:51:09Z

There are a mix of function prototypes with and without extern in the kernel sources. Standardize on not using extern for function prototypes. Function prototypes don't need to be written with extern. extern is assumed by the compiler. Its use is as unnecessary as using auto to declare automatic/local variables in a block.

rtnetlink: Remove passing of attributes into rtnl_doit functions

2013-03-22T14:31:16Z

With decnet converted, we can finally get rid of rta_buf and its computations around it. It also gets rid of the minimal header length verification since all message handlers do that explicitly anyway. Signed-off-by: Thomas Graf Signed-off-by: David S. Miller

rtnelink: remove unused parameter from rtnl_create_link().

2012-11-30T17:24:40Z

This patch removes an unused parameter (src_net) from rtnl_create_link() method and from the method single invocation, in veth. This parameter was used in the past when calling ops->get_tx_queues(src_net, tb) in rtnl_create_link(). The get_tx_queues() member of rtnl_link_ops was replaced by two methods, get_num_tx_queues() and get_num_rx_queues(), which do not get any parameter. This was done in commit d40156aa5ecbd51fed932ed4813df82b56e5ff4d by Jiri Pirko ("rtnl: allow to specify different num for rx and tx queue count"). Signed-off-by: Rami Rosen Signed-off-by: David S.

rtnl: allow to specify different num for rx and tx queue count

Also cut out unused function parameters and possible err in return value. Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

rtnetlink: ops->get_tx_queue() cannot take a const 'tb'.

rtnetlink & bonding: change args got get_tx_queues

2012-04-13T17:31:00Z

Change get_tx_queues, drop unsused arg/return value real_tx_queues, and use return by value (with error) rather than call by reference. Probably bonding should just change to LLTX and the whole get_tx_queues API could disappear! Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

rtnetlink: Fix problem with buffer allocation

2012-02-21T21:56:45Z

Implement a new netlink attribute type IFLA_EXT_MASK. The mask is a 32 bit value that can be used to indicate to the kernel that certain extended ifinfo values are requested by the user application. At this time the only mask value defined is RTEXT_FILTER_VF to indicate that the user wants the ifinfo dump to send information about the VFs belonging to the interface. This patch fixes a bug in which certain applications do not have large enough buffers to accommodate the extra information returned by the kernel with large numbers of SR-IOV virtual functions. Those applications will not send the new netlink attribute with the interface info dump request netlink messages so they will not get unexpectedly large request buffers returned by the kernel. Modifies the rtnl_calcit function to traverse the list of net devices and compute the minimum buffer size that can hold the info dumps of all matching devices based upon the filter passed in via the new netlink attribute filter mask. If no filter mask is sent then the buffer allocation defaults to NLMSG_GOODSIZE. With this change it is possible to add yet to be defined netlink attributes to the dump request which should make it fairly extensible in the future. Signed-off-by: Greg Rose Signed-off-by: David S.
