[NETLINK]: Type-safe netlink messages/attributes interface Introduces a new type-safe interface for netlink message and attributes handling. The interface is fully binary compatible with the old interface towards userspace. Besides type safety, this interface features attribute validation capabilities, simplified message contstruction, and documentation. The resulting netlink code should be smaller, less error prone and easier to understand. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S. Miller <davem@davemloft.net>

[NETLINK]: Add notification message sending interface 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.

[NET]: make netlink user -> kernel interface synchronious This patch make processing netlink user -> kernel messages synchronious. This change was inspired by the talk with Alexey Kuznetsov about current netlink messages processing. He says that he was badly wrong when introduced asynchronious user -> kernel communication. The call netlink_unicast is the only path to send message to the kernel netlink socket. But, unfortunately, it is also used to send data to the user. Before this change the user message has been attached to the socket queue and sk->sk_data_ready was called. The process has been blocked until all pending messages were processed. The bad thing is that this processing may occur in the arbitrary process context. This patch changes nlk->data_ready callback to get 1 skb and force packet processing right in the netlink_unicast. Kernel -> user path in netlink_unicast remains untouched. EINTR processing for in netlink_run_queue was changed. It forces rtnl_lock drop, but the process remains in the cycle until the message will be fully processed. So, there is no need to use this kludges now. Signed-off-by: Denis V.

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.

netlink: Fix nla_parse_nested_compat() to call nla_parse() directly The purpose of nla_parse_nested_compat() is to parse attributes which contain a struct followed by a stream of nested attributes. So far, it called nla_parse_nested() to parse the stream of nested attributes which was wrong, as nla_parse_nested() expects a container attribute as data which holds the attribute stream. It needs to call nla_parse() directly while pointing at the next possible alignment point after the struct in the beginning of the attribute. With this patch, I can no longer reproduce the reported leftover warnings. Signed-off-by: Thomas Graf <tgraf@suug.ch> Acked-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

netlink: Fix nla_parse_nested_compat() to call nla_parse() directly The purpose of nla_parse_nested_compat() is to parse attributes which contain a struct followed by a stream of nested attributes. So far, it called nla_parse_nested() to parse the stream of nested attributes which was wrong, as nla_parse_nested() expects a container attribute as data which holds the attribute stream. It needs to call nla_parse() directly while pointing at the next possible alignment point after the struct in the beginning of the attribute. With this patch, I can no longer reproduce the reported leftover warnings. Signed-off-by: Thomas Graf <tgraf@suug.ch> Acked-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

[NETLINK]: Type-safe netlink messages/attributes interface Introduces a new type-safe interface for netlink message and attributes handling. The interface is fully binary compatible with the old interface towards userspace. Besides type safety, this interface features attribute validation capabilities, simplified message contstruction, and documentation. The resulting netlink code should be smaller, less error prone and easier to understand. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
