Specifically it created a mutually exclusive\nrelationship between being a slave and a netpoll-capable device. This creates\nproblems for KVM because guests relied on needing netconsole active on a slave\ndevice to a bridge. Ideally libvirtd could just attach netconsole to the bridge\ndevice instead, but thats currently infeasible, because while the bridge device\nsupports netpoll, it requires that all slave interface also support it, but the\ntun/tap driver currently does not. The most direct solution is to teach tun/tap\nto support netpoll, which is implemented by the patch below.\n\nI\u0027ve not tested this yet, but its pretty straightforward.\n\nSigned-off-by: Neil Horman \u003cnhorman@tuxdriver.com\u003e\nReported-by: Rik van Riel \u003criel@redhat.com\u003e\nCC: Rik van Riel \u003criel@redhat.com\u003e\nCC: Maxim Krasnyansky \u003cmaxk@qualcomm.com\u003e\nCC: Cong Wang \u003camwang@redhat.com\u003e\nCC: \"David S.

It will allow us to remove a bunch of pretty\nuseless init scripts and modprobes from init scripts.\n\nThe static device node aliases will be carried in the module itself.

This might also useful for systems which still run\na plain static /dev, which is completely unsafe to use with any dynamic minor\nnumbers.\n\nNote:\nThe devname aliases must be limited to the *common* and *single*instance*\ndevice nodes, like the misc devices, and never be used for conceptually limited\nsystems like the loop devices, which should rather get fixed properly and get a\ncontrol node for losetup to talk to, instead of creating a random number of\ndevice nodes in advance, regardless if they are ever used.\n\nThis facility is to hide the mess distros are creating with too modualized\nkernels, and just to hide that these modules are not compiled-in, and not to\npaper-over broken concepts.

The problem with this is that it\nimposes restrictions on when and where the tun device can access\nthe wait queue since the tun file may change at any time due to\ndetaching and reattaching.\n\nIn particular, now that we need to use the wait queue on the\nreceive path it becomes difficult to properly synchronise this\nwith the detachment of the tun device.\n\nThis patch solves the original race in a different way. Since\nthe race is only because the underlying memory gets freed, we\ncan prevent it simply by ensuring that we don\u0027t do that until\nall tun descriptors ever attached to the device (even if they\nhave since be detached because they may still be sitting in poll)\nhave been closed.\n\nThis is done by using reference counting the attached tun file\ndescriptors. The refcount in tun-\u003esk has been reappropriated\nfor this purpose since it was already being used for that, albeit\nfrom the opposite angle.\n\nNote that we no longer zero tfile-\u003etun since tun_get will return\nNULL anyway after the refcount on tfile hits zero.
