Subject: [PATCH bpf v4 0/2] xdp: fix hang while unregistering device bound to xdp socket
Date: Wed, 26 Jun 2019 21:15:13 +0300 [thread overview]
Message-ID: <20190626181515.1640-1-i.maximets@samsung.com> (raw)
In-Reply-To: CGME20190626181520eucas1p1817d31d958b8755600f0745e92edef5a@eucas1p1.samsung.com
Version 4:
* 'xdp_umem_clear_dev' exposed to be used while unregistering.
* Added XDP socket state to track if resources already unbinded.
* Splitted in two fixes.
Version 3:
* Declaration lines ordered from longest to shortest.
* Checking of event type moved to the top to avoid unnecessary
locking.
Version 2:
* Completely re-implemented using netdev event handler.

xdp: hold device for umem regardless of zero-copy mode
