2021-03-26mptcp: move to next addr when subflow creation failGeliang Tang
When an invalid address was announced, the subflow couldn't be created for this address. Therefore mptcp_pm_nl_subflow_established couldn't be invoked. Then the next addresses in the local address list didn't have a chance to be announced. This patch invokes the new function mptcp_pm_add_addr_echoed when the address is echoed. In it, use mptcp_lookup_anno_list_by_saddr to check whether this address is in the anno_list. If it is, PM schedules the status MPTCP_PM_SUBFLOW_ESTABLISHED to invoke mptcp_pm_create_subflow_or_signal_addr to deal with the next address in the local address list.

This patch added a new helper named lookup_subflow_by_daddr to find whether the destination address is in the msk's conn_list.

2021-03-25bpf: Fix NULL pointer dereference in bpf_get_local_storage() helperYonghong Song
Jiri Olsa reported a bug ([1]) in kernel where cgroup local storage pointer may be NULL in bpf_get_local_storage() helper. There are two issues uncovered by this bug: (1). kprobe or tracepoint prog incorrectly sets cgroup local storage before prog run, (2). due to change from preempt_disable to migrate_disable, preemption is possible and percpu storage might be overwritten by other tasks. This issue (1) is fixed in [2]. This patch tried to address issue (2). The following shows how things can go wrong: task 1: bpf_cgroup_storage_set() for percpu local storage preemption happens task 2: bpf_cgroup_storage_set() for percpu local storage preemption happens task 1: run bpf program task 1 will effectively use the percpu local storage setting by task 2 which will be either NULL or incorrect ones. Instead of just one common local storage per cpu, this patch fixed the issue by permitting 8 local storages per cpu and each local storage is identified by a task_struct pointer. This way, we allow at most 8 nested preemption between bpf_cgroup_storage_set() and bpf_cgroup_storage_unset(). The percpu local storage slot is released (calling bpf_cgroup_storage_unset()) by the same task after bpf program finished running. bpf_test_run() is also fixed to use the new bpf_cgroup_storage_set() interface. The patch is tested on top of [2] with reproducer in [1]. Without this patch, kernel will emit error in 2-3 minutes. With this patch, after one hour, still no error.

2021-03-25tcp: convert elligible sysctls to u8Eric Dumazet
Many tcp sysctls are either bools or small ints that can fit into u8. Reducing space taken by sysctls can save few cache line misses when sending/receiving data while cpu caches are empty, for example after cpu idle period. This is hard to measure with typical network performance tests, but after this patch, struct netns_ipv4 has shrunk by three cache lines.

Reject NONE on set, this mode means device does not support FEC so it's a little out of place in the set interface. This should be safe to do - user space ethtool does not allow the use of NONE on set. A few drivers treat it the same as OFF, but none use it instead of OFF. Similarly reject an empty FEC mask. The common user space tool will not send such requests and most drivers correctly reject it already.

In commit 73f156a6e8c1 ("inetpeer: get rid of ip_id_count") I used a very small hash table that could be abused by patient attackers to reveal sensitive information. Switch to a dynamic sizing, depending on RAM size. Typical big hosts will now use 128x more storage (2 MB) to get a similar increase in security and reduction of hash collisions. As a bonus, use of alloc_large_system_hash() spreads allocated memory among all NUMA nodes.

2021-03-24dsa: slave: add support for TC_SETUP_FTPablo Neira Ayuso
The dsa infrastructure provides a well-defined hierarchy of devices, pass up the call to set up the flow block to the master device. From the software dataplane, the netfilter infrastructure uses the dsa slave devices to refer to the input and output device for the given skbuff. Similarly, the flowtable definition in the ruleset refers to the dsa slave port devices. This patch adds the glue code to call ndo_setup_tc with TC_SETUP_FT with the master device via the dsa slave devices. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: David S.

2021-03-24netfilter: flowtable: support for FLOW_ACTION_PPPOE_PUSHPablo Neira Ayuso
Add a PPPoE push action if layer 2 protocol is ETH_P_PPP_SES to add PPPoE flowtable hardware offload support. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2021-03-24netfilter: flowtable: bridge vlan hardware offload and switchdevFelix Fietkau
The switch might have already added the VLAN tag through PVID hardware offload. Keep this extra VLAN in the flowtable but skip it on egress. Signed-off-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2021-03-24netfilter: nft_flow_offload: use direct xmit if hardware offload is enabledPablo Neira Ayuso
If there is a forward path to reach an ethernet device and hardware offload is enabled, then use the direct xmit path. Moreover, store the real device in the direct xmit path info since software datapath uses dev_hard_header() to push the layer encapsulation headers while hardware offload refers to the real device.

2021-03-24netfilter: flowtable: add offload support for xmit path typesPablo Neira Ayuso
When the flow tuple xmit_type is set to FLOW_OFFLOAD_XMIT_DIRECT, the dst_cache pointer is not valid, and the h_source/h_dest/ifidx out fields need to be used. This patch also adds the FLOW_ACTION_VLAN_PUSH action to pass the VLAN tag to the driver. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2021-03-24netfilter: flowtable: add dsa supportPablo Neira Ayuso
Replace the master ethernet device by the dsa slave port. Packets coming in from the software ingress path use the dsa slave port as input device. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: David S. Miller <davem@davemloft.net>
