f208c4bbd4 Fix ENOENT errors when polling on Netlink socket 
When a Netlink response is issued, which a task is currently polling for
on the corresponding AF_NETLINK socket, then the poll call will return
with a ENOENT error.  This is due to the fact that the Netlink response
notifier is automatically torn down after the notification.

Fixed by making netlink_notifier_teardown a best-effort function that
does not return a result code.

4ae09a3b80 net/netlink: Redesign the logic that handles notifications of when response data is available. Signal handlers are sub-optimal inside the OS (especially after the preceding change which forces the hand). Instead, use the work queue notifiers as is done with all other network notifiers. 2019-11-28 14:20:40 -06:00

93ed8b66d9 net/netlink: Add partial support for the NETLINK poll() operation. Still missing is some signal handling logic that actually wakes up the poll() when an asynchronous NETLLINK response is available. 
So although the poll() implemenation is still not yet usable, the commit is useful because it (1) does not harm, and (2) incidentally fixes a few other issues in the NETLONK response queuing that I noted in the process.

056d704cf9 This commit brings in a fragmentary, experimental implementation of NETLINK sockets. There is not too much to that socket support on this initial commit, just the netlink socketer framework. However, I decided to bring it into master because there is a enough that I would not want to lose what is in place. And since it is dependent on CONFIG_EXPERIMENATL, its presence on master should be innocuous. 
Squashed commit of the following:

    net/netlink:  Mark netlink support as EXPERIMENTAL.
    net/netlink/netlink_sockif.c:  Add netlink_getpeername to the socket interface.
    net:  Add getpeeername() support for netlink sockets.
    include/netpacket/netlink.h:  Add a few more definitions and structures used at the NetLink interface.  Still missing many.
    net/netlink:  Add basic framework for Netlink socket support.
    include/:  Add basic Netlink definitions.
