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.

It was broken and\nconfusing to start with and subsequent patches broke it completely.\nTo give you an idea of what\u0027s broken here are some of the issues:\n\n- Very confusing comments throughout the code that imply that the\ncharacter device is a network interface in its own right, and that packets\nare passed between the two nics. Which is completely wrong.\n\n- Wrong set of ioctls is used for setting up filters. They look like\nshortcuts for manipulating state of the tun/tap network interface but\nin reality manipulate the state of the TX filter.\n\n- ioctls that were originally used for setting address of the the TX filter\ngot \"fixed\" and now set the address of the network interface itself. Which\nmade filter totaly useless.\n\n- Filtering is done too late. Instead of filtering early on, to avoid\nunnecessary wakeups, filtering is done in the read() call.\n\nThe list goes on and on :)\n\nSo the patch cleans all that up. It introduces simple and clean interface for\nsetting up TX filters (TUNSETTXFILTER + tun_filter spec) and does filtering\nbefore enqueuing the packets.\n\nTX filtering is useful in the scenarios where TAP is part of a bridge, in\nwhich case it gets all broadcast, multicast and potentially other packets when\nthe bridge is learning. So for example Ethernet tunnelling app may want to\nsetup TX filters to avoid tunnelling multicast traffic. QEMU and other\nhypervisors can push RX filtering that is currently done in the guest into the\nhost context therefore saving wakeups and unnecessary data transfer.\n\nSigned-off-by: Max Krasnyansky \u003cmaxk@qualcomm.com\u003e\nSigned-off-by: David S.
