After a short network outage, the dst_entry is timed out and put in DST_OBSOLETE_DEAD. We are in this code because arp reply comes from this neighbour after network recovers. There is a potential race condition that dst_entry is still in DST_OBSOLETE_DEAD. With that, another neighbour lookup causes more harm than good. In best case all packets in arp_queue are lost. This is counterproductive to the original goal of finding a better path for those packets. I observed a worst case with 4.x kernel where a dst_entry in DST_OBSOLETE_DEAD state is associated with loopback net_device. It leads to an ethernet header with all zero addresses. A packet with all zero source MAC address is quite deadly with mac80211, ath9k and 802.11 block ack. It fails ieee80211_find_sta_by_ifaddr in ath9k (xmit.c). Ath9k flushes tx queue (ath_tx_complete_aggr). BAW (block ack window) is not updated. BAW logic is damaged and ath9k transmission is disabled. Signed-off-by:

Current algorithm for encap keys is legacy from initial vxlan implementation and doesn't take into account all possible fields of a tunnel. For example, for a Geneve tunnel, which may have additional TLV options, they are ignored when comparing encap keys and a rule can be attached to an incorrect encap entry. Fix that by introducing encap_info_equal() operation in struct mlx5e_tc_tunnel. Geneve tunnel type uses custom implementation, which extends generic algorithm and considers options if they are set.

ct_label 0 is a default label each flow has and therefore there can be rules that match on ct_label=0 without a prior rule that set the ct_label to this value. The ct_label value is not used directly in the HW rules and instead it is mapped to some id within a defined range and this id is used to set and match the metadata register which carries the ct_label. If we have a rule that matches on ct_label=0, the hw rule will perform matching on a value that is != 0 because of the mapping from label to id. Since the metadata register default value is 0 and it was never set before to anything else by an action that sets the ct_label, there will always be a mismatch between that register and the value in the rule. To support such rule, a forced mapping of ct_label 0 to id=0 is done so that it will match the metadata register default value of 0.

Currently the mentioned helper can end-up freeing the socket wmem without waking-up any processes waiting for more write memory. If the partially orphaned skb is attached to an UDP (or raw) socket, the lack of wake-up can hang the user-space. Even for TCP sockets not calling the sk destructor could have bad effects on TSQ. Address the issue using skb_orphan to release the sk wmem before setting the new sock_efree destructor. Additionally bundle the whole ownership update in a new helper, so that later other potential users could avoid duplicate code. v1 -> v2: - use skb_orphan() instead of sort of open coding it (Eric) - provide an helper for the ownership change (Eric) Fixes: f6ba8d33 ("netem: fix skb_orphan_partial()") Suggested-by:

Currently, action creation using ACT API in replace mode is buggy. When invoking for non-existent action index 42, tc action replace action bpf obj foo.o sec <xyz> index 42 kernel creates the action, fills up the netlink response, and then just deletes the action after notifying userspace. tc action show action bpf doesn't list the action. This happens due to the following sequence when ovr = 1 (replace mode) is enabled: tcf_idr_check_alloc is used to atomically check and either obtain reference for existing action at index, or reserve the index slot using a dummy entry (ERR_PTR(-EBUSY)). This is necessary as pointers to these actions will be held after dropping the idrinfo lock, so bumping the reference count is necessary as we need to insert the actions, and notify userspace by dumping their attributes. Finally, we drop the reference we took using the tcf_action_put_many call in tcf_action_add. However, for the case where a new action is created due to free index, its refcount remains one. This when paired with the put_many call leads to the kernel setting up the action, notifying userspace of its creation, and then tearing it down. For existing actions, the refcount is still held so they remain unaffected. Fortunately due to rtnl_lock serialization requirement, such an action with refcount == 1 will not be concurrently deleted by anything else, at best CLS API can move its refcount up and down by binding to it after it has been published from tcf_idr_insert_many. Since refcount is atleast one until put_many call, CLS API cannot delete it. Also __tcf_action_put release path already ensures deterministic outcome (either new action will be created or existing action will be reused in case CLS API tries to bind to action concurrently) due to idr lock serialization. We fix this by making refcount of newly created actions as 2 in ACT API replace mode. A relaxed store will suffice as visibility is ensured only after the tcf_idr_insert_many call. Note that in case of creation or overwriting using CLS API only (i.e. bind = 1), overwriting existing action object is not allowed, and any such request is silently ignored (without error). The refcount bump that occurs in tcf_idr_check_alloc call there for existing action will pair with tcf_exts_destroy call made from the owner module for the same action. In case of action creation, there is no existing action, so no tcf_exts_destroy callback happens. This means no code changes for CLS API.

After a timeout (the default case -- reset to START when response received) just mark the monitor.enabled false.

Accessing SGE_QBASE_MAP[0-3] and SGE_QBASE_INDEX registers can lead to SGE missing doorbells under heavy traffic. So, only collect them when adapter is idle. Also update the regdump range to skip collecting these registers. Fixes: 80a95a80 ("cxgb4: collect SGE PF/VF queue map") Signed-off-by:

In myri10ge_sw_tso, the skb_list_walk_safe macro will set (curr) = (segs) and (next) = (curr)->next. If status!=0 is true, the memory pointed by curr and segs will be free by dev_kfree_skb_any(curr). But later, the segs is used by segs = segs->next and causes a uaf. As (next) = (curr)->next, my patch replaces seg->next to next.

The two patch are by Oliver Hartkopp. He fixes length check in the proto_ops::getname callback for the CAN RAW, BCM and ISOTP protocols, which were broken by the introduction of the J1939 protocol. The last patch is by me and fixes the a BUILD_BUG_ON() check which triggers on ARCH=arm with CONFIG_AEABI unset. ==================== Signed-off-by:

Ido Schimmel says: ==================== mlxsw: spectrum: Fix ECN marking in tunnel decapsulation Patch #1 fixes a discrepancy between the software and hardware data paths with regards to ECN marking after decapsulation. See the changelog for a detailed description. Patch #2 extends the ECN decap test to cover all possible combinations of inner and outer ECN markings. The test passes over both data paths. v2: * Only set ECT(1) if inner is ECT(0) * Introduce a new helper to determine inner ECN. Share it between NVE and IP-in-IP tunnels * Extend the selftest ==================== Signed-off-by:

Cited commit changed the behavior of the software data path with regards to the ECN marking of decapsulated packets. However, the commit did not change other callers of __INET_ECN_decapsulate(), namely mlxsw. The driver is using the function in order to ensure that the hardware and software data paths act the same with regards to the ECN marking of decapsulated packets. The discrepancy was uncovered by commit 5aa3c334 ("selftests: forwarding: vxlan_bridge_1d: Fix vxlan ecn decapsulate value") that aligned the selftest to the new behavior. Without this patch the selftest passes when used with veth pairs, but fails when used with mlxsw netdevs. Fix this by instructing the device to propagate the ECT(1) mark from the outer header to the inner header when the inner header is ECT(0), for both NVE and IP-in-IP tunnels. A helper is added in order not to duplicate the code between both tunnel types. Fixes: b7237487 ("tunnel: Propagate ECT(1) when decapsulating as recommended by RFC6040") Signed-off-by:
