This allows the driver to pass in struct ieee80211_tx_status directly. Make ieee80211_tx_status_noskb a wrapper around it. As with ieee80211_tx_status_noskb, there is no _ni variant of this call, because it probably won't be needed. Even if the driver won't provide any extra status info other than what's in struct ieee80211_tx_info already, it can optimize status reporting this way by passing in the station pointer.

ieee80211_frame_acked is called when a frame is acked by the peer. In case this is a management frame, we check if this an SMPS frame, in which case we can update our antenna configuration. When we parse the management frame we look at the category in case it is an action frame. That byte sits after the IV in case the frame was encrypted. This means that if the frame was encrypted, we basically look at the IV instead of looking at the category. It is then theorically possible that we think that an SMPS action frame was acked where really we had another frame that was encrypted. Since the only management frame whose ack needs to be tracked is the SMPS action frame, and that frame is not a robust management frame, it will never be encrypted. The easiest way to fix this problem is then to not look at frames that were encrypted.

This patch implements the idea to have multiple scheduled scan requests running concurrently. It mainly illustrates how to deal with the incoming request from user-space in terms of backward compatibility. In order to use multiple scheduled scans user-space needs to provide a flag attribute NL80211_ATTR_SCHED_SCAN_MULTI to indicate support. If not the request is treated as a legacy scan. Drivers currently supporting scheduled scan are now indicating they support a single scheduled scan request. This obsoletes WIPHY_FLAG_SUPPORTS_SCHED_SCAN.

This provides a generic SKB based non-optimized XDP path which is used if either the driver lacks a specific XDP implementation, or the user requests it via a new IFLA_XDP_FLAGS value named XDP_FLAGS_SKB_MODE. It is arguable that perhaps I should have required something like this as part of the initial XDP feature merge. I believe this is critical for two reasons: 1) Accessibility. More people can play with XDP with less dependencies. Yes I know we have XDP support in virtio_net, but that just creates another depedency for learning how to use this facility. I wrote this to make life easier for the XDP newbies. 2) As a model for what the expected semantics are. If there is a pure generic core implementation, it serves as a semantic example for driver folks adding XDP support. One thing I have not tried to address here is the issue of XDP_PACKET_HEADROOM, thanks to Daniel for spotting that. It seems incredibly expensive to do a skb_cow(skb, XDP_PACKET_HEADROOM) or whatever even if the XDP program doesn't try to push headers at all. I think we really need the verifier to somehow propagate whether certain XDP helpers are used or not. v5: - Handle both negative and positive offset after running prog - Fix mac length in XDP_TX case (Alexei) - Use rcu_dereference_protected() in free_netdev (kbuild test robot) v4: - Fix MAC header adjustmnet before calling prog (David Ahern) - Disable LRO when generic XDP is installed (Michael Chan) - Bypass qdisc et al. on XDP_TX and record the event (Alexei) - Do not perform generic XDP on reinjected packets (DaveM) v3: - Make sure XDP program sees packet at MAC header, push back MAC header if we do XDP_TX. (Alexei) - Elide GRO when generic XDP is in use. (Alexei) - Add XDP_FLAG_SKB_MODE flag which the user can use to request generic XDP even if the driver has an XDP implementation. (Alexei) - Report whether SKB mode is in use in rtnl_xdp_fill() via XDP_FLAGS attribute. (Daniel) v2: - Add some "fall through" comments in switch statements based upon feedback from Andrew Lunn - Use RCU for generic xdp_prog, thanks to Johannes Berg.

per discussion at netconf/netdev: When we have an action that is capable of branching (example a policer), we can achieve a continuation of the action graph by programming a "continue" where we find an exact replica of the same filter rule with a lower priority and the remainder of the action graph. When you have 100s of thousands of filters which require such a feature it gets very inefficient to do two lookups. This patch completes a leftover feature of action codes. Its time has come. Example below where a user labels packets with a different skbmark on ingress of a port depending on whether they have/not exceeded the configured rate. This mark is then used to make further decisions on some egress port. #rate control, very low so we can easily see the effect sudo $TC actions add action police rate 1kbit burst 90k \ conform-exceed pipe/jump 2 index 10 # skbedit index 11 will be used if the user conforms sudo $TC actions add action skbedit mark 11 ok index 11 # skbedit index 12 will be used if the user does not conform sudo $TC actions add action skbedit mark 12 ok index 12 #lets bind the user .. sudo $TC filter add dev $ETH parent ffff: protocol ip prio 8 u32 \ match ip dst 127.0.0.8/32 flowid 1:10 \ action police index 10 \ action skbedit index 11 \ action skbedit index 12 #run a ping -f and see what happens.. # jhs@foobar:~$ sudo $TC -s filter ls dev $ETH parent ffff: protocol ip filter pref 8 u32 filter pref 8 u32 fh 800: ht divisor 1 filter pref 8 u32 fh 800::800 order 2048 key ht 800 bkt 0 flowid 1:10 (rule hit 2800 success 1005) match 7f000008/ffffffff at 16 (success 1005 ) action order 1: police 0xa rate 1Kbit burst 23440b mtu 2Kb action pipe/jump 2 overhead 0b ref 2 bind 1 installed 207 sec used 122 sec Action statistics: Sent 84420 bytes 1005 pkt (dropped 0, overlimits 721 requeues 0) backlog 0b 0p requeues 0 action order 2: skbedit mark 11 pass index 11 ref 2 bind 1 installed 204 sec used 122 sec Action statistics: Sent 60564 bytes 721 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 action order 3: skbedit mark 12 pass index 12 ref 2 bind 1 installed 201 sec used 122 sec Action statistics: Sent 23856 bytes 284 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 Not bad, about 28% non-conforming packets..

Merge tag 'linux-can-next-for-4.12-20170425' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next Marc Kleine-Budde says: ==================== pull-request: can-next 2017-04-25 this is a pull request of 21 patches for net-next/master. There are 4 patches by Stephane Grosjean for the PEAK PCAN-PCIe FD CAN-FD boards. The next 7 patches are by Mario Huettel, which add support for M_CAN IP version >= v3.1.x to the m_can driver. A patch by Remigiusz Kołłątaj adds support for the Microchip CAN BUS Analyzer. 8 patches by Oliver Hartkopp complete the initial CAN network namespace support. Wei Yongjun's patch for the ti_hecc driver fixes the return value check in the probe function. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

commit 4fbae7d8 ("ipvlan: Introduce l3s mode") added registration of netfilter hooks via nf_register_hooks(). This API provides the illusion of 'global' netfilter hooks by placing the hooks in all current and future network namespaces. In case of ipvlan the hook appears to be only needed in the namespace that contains the ipvlan master device (i.e., usually init_net), so placing them in all namespaces is not needed. This switches ipvlan driver to pernet operations, and then only registers hooks in namespaces where a ipvlan master device is set to l3s mode. Extra care has to be taken when the master device is moved to another namespace, as we might have to 'move' the netfilter hooks too. This is done by storing the namespace the ipvlan port was created in. On REGISTER event, do (un)register operations in the old/new namespaces. This will also allow removal of the nf_register_hooks() in a future patch. Cc: Mahesh Bandewar <maheshb@google.com> Signed-off-by: NFlorian Westphal <fw@strlen.de> Signed-off-by: NDavid S.

In case of error, the function devm_ioremap_resource() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().
