Pablo Neira Ayuso says: ==================== netfilter/ipvs updates for net-next The following patchset contains Netfilter updates for your net-next tree, this includes the NAT redirection support for nf_tables, the cgroup support for nft meta and conntrack zone support for the connlimit match. Coming after those, a bunch of sparse warning fixes, missing netns bits and cleanups. More specifically, they are: 1) Prepare IPv4 and IPv6 NAT redirect code to use it from nf_tables, patches from Arturo Borrero. 2) Introduce the nf_tables redir expression, from Arturo Borrero. 3) Remove an unnecessary assignment in ip_vs_xmit/__ip_vs_get_out_rt(). Patch from Alex Gartrell. 4) Add nft_log_dereference() macro to the nf_log infrastructure, patch from Marcelo Leitner. 5) Add some extra validation when registering logger families, also from Marcelo. 6) Some spelling cleanups from stephen hemminger. 7) Fix sparse warning in nf_logger_find_get(). 8) Add cgroup support to nf_tables meta, patch from Ana Rey. 9) A Kconfig fix for the new redir expression and fix sparse warnings in the new redir expression. 10) Fix several sparse warnings in the netfilter tree, from Florian Westphal. 11) Reduce verbosity when OOM in nfnetlink_log. User can basically do nothing when this situation occurs. 12) Add conntrack zone support to xt_connlimit, again from Florian. 13) Add netnamespace support to the h323 conntrack helper, contributed by Vasily Averin. 14) Remove unnecessary nul-pointer checks before free_percpu() and module_put(), from Markus Elfring. 15) Use pr_fmt in nfnetlink_log, again patch from Marcelo Leitner. ==================== Signed-off-by: David S.

2014-11-24ipvlan: Initial check-in of the IPVLAN driver.Mahesh Bandewar
This driver is very similar to the macvlan driver except that it uses L3 on the frame to determine the logical interface while functioning as packet dispatcher. It inherits L2 of the master device hence the packets on wire will have the same L2 for all the packets originating from all virtual devices off of the same master device. This driver was developed keeping the namespace use-case in mind. Hence most of the examples given here take that as the base setup where main-device belongs to the default-ns and virtual devices are assigned to the additional namespaces. The device operates in two different modes and the difference in these two modes in primarily in the TX side. (a) L2 mode : In this mode, the device behaves as a L2 device. TX processing upto L2 happens on the stack of the virtual device associated with (namespace). Packets are switched after that into the main device (default-ns) and queued for xmit. RX processing is simple and all multicast, broadcast (if applicable), and unicast belonging to the address(es) are delivered to the virtual devices. (b) L3 mode : In this mode, the device behaves like a L3 device. TX processing upto L3 happens on the stack of the virtual device associated with (namespace). Packets are switched to the main-device (default-ns) for the L2 processing. Hence the routing table of the default-ns will be used in this mode. RX processins is somewhat similar to the L2 mode except that in this mode only Unicast packets are delivered to the virtual device while main-dev will handle all other packets. The devices can be added using the "ip" command from the iproute2 package - ip link add link <master> <virtual> type ipvlan mode [ l2 | l3 ] Signed-off-by: Mahesh Bandewar <maheshb@google.com> Cc: Eric Dumazet <edumazet@google.com> Cc: Maciej Żenczykowski <maze@google.com> Cc: Laurent Chavey <chavey@google.com> Cc: Tim Hockin <thockin@google.com> Cc: Brandon Philips <brandon.philips@coreos.com> Cc: Pavel Emelianov <xemul@parallels.com> Signed-off-by: David S.

2014-11-24drm/i915: Ignore SURFLIVE and flip counter when the GPU gets resetVille Syrjälä
During a GPU reset we need to get pending page flip cleared out since the ring contents are gone and flip will never complete on its own. This used to work until the mmio vs. CS flip race detection came about. That piece of code is looking for a specific surface address in the SURFLIVE register, but as a flip to that address may never happen the check may never pass. So we should just skip the SURFLIVE and flip counter checks when the GPU gets reset. intel_display_handle_reset() tries to effectively complete the flip anyway by calling .update_primary_plane(). But that may not satisfy the conditions of the mmio vs. CS race detection since there's no guarantee that a modeset didn't sneak in between the GPU reset and intel_display_handle_reset(). Such a modeset will not wait for pending flips due to the ongoing GPU reset, and then the primary plane updates performed by intel_display_handle_reset() will already use the new surface address, and thus the surface address the flip is waiting for might never appear in SURFLIVE. The result is that the flip will never complete and attempts to perform further page flips will fail with -EBUSY. During the GPU reset intel_crtc_has_pending_flip() will return false regardless, so the deadlock with a modeset vs. the error work acquiring crtc->mutex was avoided. And the reset_counter check in intel_crtc_has_pending_flip() actually made this bug even less severe since it allowed normal modesets to go through even though there's a pending flip. This is a regression introduced by me here: commit 75f7f3ec600524c9544cc31695155f1a9ddbe1d9 Author: Ville Syrjälä <ville.syrjala@linux.intel.com> Date: Tue Apr 15 21:41:34 2014 +0300 drm/i915: Fix mmio vs. CS flip race on ILK+ Testcase: igt/kms_flip/flip-vs-panning-vs-hang Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: stable@vger.kernel.org Signed-off-by: Jani Nikula <jani.nikula@intel.com>
