[IPV4]: introduce nla_get_be32()/NLA_PUT_BE32()

2006-09-29T00:54:14Z

net-endian counterparts of nla_get_u32()/NLA_PUT_U32() Signed-off-by: Al Viro Signed-off-by: David S. Miller

[Netlink]: add nla_validate_nested()

2006-09-25T22:54:03Z

[NETLINK]: add nla_for_each_nested() to the interface list

2006-09-25T22:53:37Z

At the top of include/net/netlink.h is a list of Netlink interfaces, however, the nla_for_each_nested() macro was not listed. This patch adds this interface to the list at the top of the header file. Signed-off-by: Paul Moore Signed-off-by: David S. Miller

[NETLINK]: Improve string attribute validation

2006-09-22T22:18:24Z

Introduces a new attribute type NLA_NUL_STRING to support NUL terminated strings. Attributes of this kind require to carry a terminating NUL within the maximum specified in the policy. The `old' NLA_STRING which is not required to be NUL terminated is extended to provide means to specify a maximum length of the string. Aims at easing the pain with using nla_strlcpy() on temporary buffers. Signed-off-by: Thomas Graf Signed-off-by: David S. Miller

[NETLINK]: remove third bogus argument from NLA_PUT_FLAG

2006-09-22T22:18:18Z

This patch removes the 'value' argument from NLA_PUT_FLAG which is unused anyway. The documentation comment was already correct so it doesn't need an update :) Signed-off-by: Johannes Berg Signed-off-by: David S. Miller

[IPv4]: FIB configuration using struct fib_config

2006-09-22T21:55:04Z

Introduces struct fib_config replacing the ugly struct kern_rta prone to ordering issues. Avoids creating faked netlink messages for auto generated routes or requests via ioctl. A new interface net/nexthop.h is added to help navigate through nexthop configuration arrays. A new struct nl_info will be used to carry the necessary netlink information to be used for notifications later on. Signed-off-by: Thomas Graf Signed-off-by: David S. Miller

[RTNETLINK]: Add rtnetlink notification interface

2006-09-22T21:54:50Z

Adds rtnl_notify() to send rtnetlink notification messages and rtnl_set_sk_err() to report notification errors as socket errors in order to indicate the need of a resync due to loss of events. nlmsg_report() is added to properly document the meaning of NLM_F_ECHO.

[NETLINK]: Add notification message sending interface

2006-09-22T21:54:49Z

Adds nlmsg_notify() implementing proper notification logic. The message is multicasted to all listeners in the group. The applications the requests orignates from can request a unicast back report in which case said socket will be excluded from the multicast to avoid duplicated notifications. nlmsg_multicast() is extended to take allocation flags to allow notification in atomic contexts.

[NETLINK]: Extend netlink messaging interface

2006-09-22T21:53:43Z

Adds: nlmsg_get_pos() return current position in message nlmsg_trim() trim part of message nla_reserve_nohdr(skb, len) reserve room for an attribute w/o hdr nla_put_nohdr(skb, len, data) add attribute w/o hdr nla_find_nested() find attribute in nested attributes Fixes nlmsg_new() to take allocation flags and consider size.

[NETLINK]: Generic netlink receive queue processor

2005-11-10T01:26:40Z

Introduces netlink_run_queue() to handle the receive queue of a netlink socket in a generic way. Processes as much as there was in the queue upon entry and invokes a callback function for each netlink message found. The callback function may refuse a message by returning a negative error code but setting the error pointer to 0 in which case netlink_run_queue() will return with a qlen != 0.
