In ieee80211_deliver_skb_to_local_stack intercepts EAPoL frames if mac80211 is configured to do so and forwards the contents over nl80211. During this process some additional data is also forwarded, including whether the frame was received encrypted or not. Unfortunately just prior to the call to ieee80211_deliver_skb_to_local_stack, skb->cb is cleared, resulting in incorrect data being exposed over nl80211.

We need to use a different firmware for C0 versions of killer Qu NICs. Add structures for them and handle them in the if block that detects C0 revisions. Additionally, instead of having an inclusive check for QnJ devices, make the selection exclusive, so that switching to QnJ is the exception, not the default. This prevents us from having to add all the non-QnJ cards to an exclusion list. To do so, only go into the QnJ block if the device has an RF ID type HR and HW revision QnJ.

A similar workaround for the suspend/resume problem is needed for yet another ASUS machines, P6X models. Like the previous fix, the BIOS doesn't provide the standard DMI_SYS_* entry, so again DMI_BOARD_* entries are used instead. Reported-and-tested-by:

Jakub Kicinski says: ==================== nfp: flower: fix bugs in merge tunnel encap code John says: There are few bugs in the merge encap code that have come to light with recent driver changes. Effectively, flow bind callbacks were being registered twice when using internal ports (new 'busy' code triggers this). There was also an issue with neighbour notifier messages being ignored for internal ports. ==================== Signed-off-by: -
John Hurley authored
Recent code changes to NFP allowed the offload of neighbour entries to FW when the next hop device was an internal port. This allows for offload of tunnel encap when the end-point IP address is applied to such a port. Unfortunately, the neighbour event handler still rejects events that are not associated with a repr dev and so the firmware neighbour table may get out of sync for internal ports. Fix this by allowing internal port neighbour events to be correctly processed. Fixes: 45756dfe ("nfp: flower: allow tunnels to output to internal port") Signed-off-by:

Internal port TC offload is implemented through user-space applications (such as OvS) by adding filters at egress via TC clsact qdiscs. Indirect block offload support in the NFP driver accepts both ingress qdisc binds and egress binds if the device is an internal port. However, clsact sends bind notification for both ingress and egress block binds which can lead to the driver registering multiple callbacks and receiving multiple notifications of new filters. Fix this by rejecting ingress block bind callbacks when the port is internal and only adding filter callbacks for egress binds.

This reverts commit 0ee1f473. The commit 0ee1f473 ("r8152: napi hangup fix after disconnect") adds a check about RTL8152_UNPLUG to determine if calling napi_disable() is invalid in rtl8152_close(), when rtl8152_disconnect() is called. This avoids to use napi_disable() after calling netif_napi_del(). Howver, commit ffa9fec3 ("r8152: set RTL8152_UNPLUG only for real disconnection") causes that RTL8152_UNPLUG is not always set when calling rtl8152_disconnect(). Therefore, I have to revert commit 0ee1f473 ("r8152: napi hangup fix after disconnect"), first. And submit another patch to fix it. Signed-off-by:

Action sample doesn't properly handle psample_group pointer in overwrite case. Following issues need to be fixed: - In tcf_sample_init() function RCU_INIT_POINTER() is used to set s->psample_group, even though we neither setting the pointer to NULL, nor preventing concurrent readers from accessing the pointer in some way. Use rcu_swap_protected() instead to safely reset the pointer. - Old value of s->psample_group is not released or deallocated in any way, which results resource leak. Use psample_group_put() on non-NULL value obtained with rcu_swap_protected(). - The function psample_group_put() that released reference to struct psample_group pointed by rcu-pointer s->psample_group doesn't respect rcu grace period when deallocating it. Extend struct psample_group with rcu head and use kfree_rcu when freeing it. Fixes: 5c5670fa ("net/sched: Introduce sample tc action") Signed-off-by:

Currently, the ibmvnic driver will not schedule device resets if the device is being removed, but does not check the device state before the reset is actually processed. This leads to a race where a reset is scheduled with a valid device state but is processed after the driver has been removed, resulting in an oops. Fix this by checking the device state before processing a queued reset event. Reported-by:

Only the first fragment in a datagram contains the L4 headers. When the Open vSwitch module parses a packet, it always sets the IP protocol field in the key, but can only set the L4 fields on the first fragment. The original behavior would not clear the L4 portion of the key, so garbage values would be sent in the key for "later" fragments. This patch clears the L4 fields in that circumstance to prevent sending those garbage values as part of the upcall. Signed-off-by:

When IP fragments are reassembled before being sent to conntrack, the key from the last fragment is used. Unless there are reordering issues, the last fragment received will not contain the L4 ports, so the key for the reassembled datagram won't contain them. This patch updates the key once we have a reassembled datagram. The handle_fragments() function works on L3 headers so we pull the L3/L4 flow key update code from key_extract into a new function 'key_extract_l3l4'. Then we add a another new function ovs_flow_key_update_l3l4() and export it so that it is accessible by handle_fragments() for conntrack packet reassembly. Co-authored-by:

Vladimir Rutsky reported stuck TCP sessions after memory pressure events. Edge Trigger epoll() user would never receive an EPOLLOUT notification allowing them to retry a sendmsg(). Jason tested the case of sk_stream_alloc_skb() returning NULL, but there are other paths that could lead both sendmsg() and sendpage() to return -1 (EAGAIN), with an empty skb queued on the write queue. This patch makes sure we remove this empty skb so that Jason code can detect that the queue is empty, and call sk->sk_write_space(sk) accordingly.

After witnessing the discussion in https://lkml.org/lkml/2019/8/14/151 w.r.t. ioctl extensibility, it became clear that such an issue might prevent that the 3 RSV bits inside the DSA 802.1Q tag might also suffer the same fate and be useless for further extension. So clearly specify that the reserved bits should currently be transmitted as zero and ignored on receive. The DSA tagger already does this (and has always did), and is the only known user so far (no Wireshark dissection plugin, etc). So there should be no incompatibility to speak of.

Commit 34786005 ("net: phy: prevent PHYs w/o Clause 22 regs from calling genphy_config_aneg") introduced a check that aborts phy_config_aneg() if the phy is a C45 phy. This causes phy_state_machine() to call phy_error() so that the phy ends up in PHY_HALTED state. Instead of returning -EOPNOTSUPP, call genphy_c45_config_aneg() (analogous to the C22 case) so that the state machine can run correctly. genphy_c45_config_aneg() closely resembles mv3310_config_aneg() in drivers/net/phy/marvell10g.c, excluding vendor specific configurations for 1000BaseT.

The net pointer in struct xt_tgdtor_param is not explicitly initialized therefore is still NULL when dereferencing it. So we have to find a way to pass the correct net pointer to ipt_destroy_target(). The best way I find is just saving the net pointer inside the per netns struct tcf_idrinfo, which could make this patch smaller.
