* net/tls: fix sign extension issue when left shifting u16 valueColin Ian King2020-06-301-1/+1
| | | | | | | | | | | | | Left shifting the u16 value promotes it to a int and then it gets sign extended to a u64. If len << 16 is greater than 0x7fffffff then the upper bits get set to 1 because of the implicit sign extension. Fix this by casting len to u64 before shifting it.

| * batman-adv: Introduce a configurable per interface hop penaltyLinus Lüssing2020-06-261-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some setups multiple hard interfaces with similar link qualities or throughput values are available. But people have expressed the desire to consider one of them as a backup only. Some creative solutions are currently in use: Such people are configuring multiple batman-adv mesh/soft interfaces, wire them together with some veth pairs and then tune the hop penalty to achieve an effect similar to a tunable per interface hop penalty. This patch introduces a new, configurable, per hard interface hop penalty to simplify such setups.

* | ethtool: Add link extended stateAmit Cohen2020-06-293-0/+95
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, drivers can only tell whether the link is up/down using LINKSTATE_GET, but no additional information is given. Add attributes to LINKSTATE_GET command in order to allow drivers to expose the user more information in addition to link state to ease the debug process, for example, reason for link down state. Extended state consists of two attributes - link_ext_state and link_ext_substate. The idea is to avoid 'vendor specific' states in order to prevent drivers to use specific link_ext_state that can be in the future common link_ext_state. The substates allows drivers to add more information to the common link_ext_state. For example, vendor can expose 'Autoneg' as link_ext_state and add 'No partner detected during force mode' as link_ext_substate. If a driver cannot pinpoint the extended state with the substate accuracy, it is free to expose only the extended state and omit the substate attribute.

The Channel/RQ is selected according to the socket's rxq index. A new TLS-RX workqueue is used to allow asynchronous addition of steering rules, out of the NAPI context. It will be also used in a downstream patch in the resync procedure. Feature is OFF by default. Can be turned on by: $ ethtool -K <if> tls-hw-rx-offload on 4) Added mlx5 kTLS sw stats and new counters are documented in Documentation/networking/tls-offload.rst rx_tls_ctx - number of TLS RX HW offload contexts added to device for decryption. rx_tls_ooo - number of RX packets which were part of a TLS stream but did not arrive in the expected order and triggered the resync procedure. rx_tls_del - number of TLS RX HW offload contexts deleted from device (connection has finished). rx_tls_err - number of RX packets which were part of a TLS stream but were not decrypted due to unexpected error in the state machine. 5) Asynchronous RX resync a. The NIC driver indicates that it would like to resync on some TLS record within the received packet (P), but the driver does not know (yet) which of the TLS records within the packet. At this stage, the NIC driver will query the device to find the exact TCP sequence for resync (tcpsn), however, the driver does not wait for the device to provide the response. b. Eventually, the device responds, and the driver provides the tcpsn within the resync packet to KTLS. Now, KTLS can check the tcpsn against any processed TLS records within packet P, and also against any record that is processed in the future within packet P. The asynchronous resync path simplifies the device driver, as it can save bits on the packet completion (32-bit TCP sequence), and pass this information on an asynchronous command instead.

Filters attached at "early_drop" block are executed as packets are early-dropped, those attached at the "mark" block are executed as packets are ECN-marked. Two new attributes are introduced: TCA_RED_EARLY_DROP_BLOCK with the block index for the "early_drop" qevent, and TCA_RED_MARK_BLOCK for the "mark" qevent. Absence of these attributes signifies "don't care": no block is allocated in that case, or the existing blocks are left intact in case of the change callback. For purposes of offloading, blocks attached to these qevents appear with newly-introduced binder types, FLOW_BLOCK_BINDER_TYPE_RED_EARLY_DROP and FLOW_BLOCK_BINDER_TYPE_RED_MARK.

The data to keep and the functions to invoke to maintain a qevent will be largely the same between qevents. Therefore introduce sched-wide helpers for qevent management. Currently, similarly to ingress and egress blocks of clsact pseudo-qdisc, blocks attachment cannot be changed after the qdisc is created. To that end, add a helper tcf_qevent_validate_change(), which verifies whether block index attribute is not attached, or if it is, whether its value matches the current one (i.e. there is no material change). The function tcf_qevent_handle() should be invoked when qdisc hits the "interesting event" corresponding to a block. This function releases root lock for the duration of executing the attached filters, to allow packets generated through user actions (notably mirred) to be reinserted to the same qdisc tree.

Should this processing lead to a situation where a new packet is to be enqueued on the same port, holding the root lock would lead to deadlocks. To solve the issue, qevent handler needs to unlock and relock the root lock when necessary. To that end, add the root lock argument to the qdisc op enqueue, and propagate throughout.

For the record, I posting here his cover letter explaining the problem: A crash happened on ppc64le when running ltp network tests triggered by "rmmod iptable_mangle". See previous discussion in this thread: https://lists.openwall.net/netdev/2020/06/03/161 . In the crash I found in iptable_mangle_hook() that state->net->ipv4.iptable_mangle=NULL causing a NULL pointer dereference. net->ipv4.iptable_mangle is set to NULL in +iptable_mangle_net_exit() and called when ip_mangle modules is unloaded. A rmmod task was found running in the crash dump. A 2nd crash showed the same problem when running "rmmod iptable_filter" (net->ipv4.iptable_filter=NULL). To fix this I added .pre_exit hook in all iptable_foo.c. The pre_exit will un-register the underlying hook and exit would do the table freeing. The netns core does an unconditional +synchronize_rcu after the pre_exit hooks insuring no packets are in flight that have picked up the pointer before completing the un-register. These patches include changes for both iptables and ip6tables. We tested this fix with ltp running iptables01.sh and iptables01.sh -6 a loop for 72 hours. 4) Add a selftest for conntrack helper assignment, from Florian Westphal. ==================== Signed-off-by: David S.

We shouldn't assume that it's the chip power-on defaults, BIOS or boot loader could have changed this. Or in case of dual-boot systems the other OS could leave the PHY in whatever state."

The error packet has duplicated ESP trailer due to double validate_xmit_xfrm calls. The first call is from ip_output, but the packet cannot be sent because netif_xmit_frozen_or_stopped is true and the packet gets dev_requeue_skb. The second call is from NET_TX softirq. However after the first call, the packet already has the ESP trailer. Fix by marking the skb with XFRM_XMIT bit after the packet is handled by validate_xmit_xfrm to avoid duplicate ESP trailer insertion.

But, in the case of the vxlan, 10 recursion limit value results in a stack overflow. In the current code, the nested interface is limited by 8 depth. There is no critical reason that the recursion limitation value should be 10. So, it would be good to be the same value with the limitation value of nesting interface depth.
