The > comparison is intended to be >= to prevent reading beyond the end of the ps->vlans[] array. It doesn't affect run time though because the ps->vlans[] array has VLAN_N_VID (4096) elements and the vlan->vid cannot be > 4094 because it is checked earlier. Signed-off-by:

Multicast entries in the MAC table use the high bits of the MAC address to encode the ports that should get the packets. But this port mask does not work for the CPU port, to receive these packets on the CPU port the MAC_CPU_COPY flag must be set. Because of this IPv6 was effectively not working because neighbor solicitations were never received. This was not apparent before commit 9403c158 (net: mscc: ocelot: support IPv4, IPv6 and plain Ethernet mdb entries) as the IPv6 entries were broken so all incoming IPv6 multicast was then treated as unknown and flooded on all ports. To fix this problem rework the ocelot_mact_learn() to set the MAC_CPU_COPY flag when a multicast entry that target the CPU port is added. For this we have to read back the ports endcoded in the pseudo MAC address by the caller. It is not a very nice design but that avoid changing the callers and should make backporting easier.

Receiving ACK with a valid SYN cookie, cookie_v4_check() allocates struct request_sock and then can allocate inet_rsk(req)->ireq_opt. After that, tcp_v4_syn_recv_sock() allocates struct sock and copies ireq_opt to inet_sk(sk)->inet_opt. Normally, tcp_v4_syn_recv_sock() inserts the full socket into ehash and sets NULL to ireq_opt. Otherwise, tcp_v4_syn_recv_sock() has to reset inet_opt by NULL and free the full socket. The commit 01770a16 ("tcp: fix race condition when creating child sockets from syncookies") added a new path, in which more than one cores create full sockets for the same SYN cookie. Currently, the core which loses the race frees the full socket without resetting inet_opt, resulting in that both sock_put() and reqsk_put() call kfree() for the same memory: sock_put sk_free __sk_free sk_destruct __sk_destruct sk->sk_destruct/inet_sock_destruct kfree(rcu_dereference_protected(inet->inet_opt, 1)); reqsk_put reqsk_free __reqsk_free req->rsk_ops->destructor/tcp_v4_reqsk_destructor kfree(rcu_dereference_protected(inet_rsk(req)->ireq_opt, 1)); Calling kmalloc() between the double kfree() can lead to use-after-free, so this patch fixes it by setting NULL to inet_opt before sock_put(). As a side note, this kind of issue does not happen for IPv6. This is because tcp_v6_syn_recv_sock() clones both ipv6_opt and pktopts which correspond to ireq_opt in IPv4.

Fix incorrect signed_{sub,add32}_overflows() input types (and a related buggy comment). It looks like this might have slipped in via copy/paste issue, also given prior to 3f50f132 ("bpf: Verifier, do explicit ALU32 bounds tracking") the signature of signed_sub_overflows() had s64 a and s64 b as its input args whereas now they are truncated to s32. Thus restore proper types. Also, the case of signed_add32_overflows() is not consistent to signed_sub32_overflows(). Both have s32 as inputs, therefore align the former.

This comes from an end-user request, where they're running multiple VMs on hosts with bonded interfaces connected to some interest switch topologies, where 802.3ad isn't an option. They're currently running a proprietary solution that effectively achieves load-balancing of VMs and bandwidth utilization improvements with a similar form of transmission algorithm. Basically, each VM has it's own vlan, so it always sends its traffic out the same interface, unless that interface fails. Traffic gets split between the interfaces, maintaining a consistent path, with failover still available if an interface goes down. Unlike bond_eth_hash(), this hash function is using the full source MAC address instead of just the last byte, as there are so few components to the hash, and in the no-vlan case, we would be returning just the last byte of the source MAC as the hash value. It's entirely possible to have two NICs in a bond with the same last byte of their MAC, but not the same MAC, so this adjustment should guarantee distinct hashes in all cases. This has been rudimetarily tested to provide similar results to the proprietary solution it is aiming to replace. A patch for iproute2 is also posted, to properly support the new mode there as well.

The commit dbd50f23 ("net: move the hsize check to the else block in skb_segment") introduced a data corruption for devices supporting scatter-gather. The problem boils down to signed/unsigned comparison given unexpected results: if signed 'hsize' is negative, it will be considered greater than a positive 'len', which is unsigned. This commit addresses resorting to the old checks order, so that 'hsize' never has a negative value when compared with 'len'. v1 -> v2: - reorder hsize checks instead of explicit cast (Alex) Bisected-by:

Heiner Kallweit reported that some skbs were sent with the following invalid GSO properties : - gso_size > 0 - gso_type == 0 This was triggerring a WARN_ON_ONCE() in rtl8169_tso_csum_v2. Juerg Haefliger was able to reproduce a similar issue using a lan78xx NIC and a workload mixing TCP incoming traffic and forwarded packets. The problem is that tcp_add_backlog() is writing over gso_segs and gso_size even if the incoming packet will not be coalesced to the backlog tail packet. While skb_try_coalesce() would bail out if tail packet is cloned, this overwriting would lead to corruptions of other packets cooked by lan78xx, sharing a common super-packet. The strategy used by lan78xx is to use a big skb, and split it into all received packets using skb_clone() to avoid copies. The drawback of this strategy is that all the small skb share a common struct skb_shared_info. This patch rewrites TCP gso_size/gso_segs handling to only happen on the tail skb, since skb_try_coalesce() made sure it was not cloned.

The CPSW3g integrated in MAIN domain and can be configured in multi port or switch modes. In this series only multi port mode is enabled. The initial version of switchdev support was introduced by Vignesh Raghavendra [2] and work is in progress. The overall functionality and DT bindings are similar to other K3 CPSWxg versions, so DT binding changes are minimal and driver is mostly re-used for TI K3 AM642x CPSW3g. The main difference is that TI K3 AM642x SoC is not fully DMA coherent and instead DMA coherency is supported per DMA channel. Patches 1-2 - DT bindings update Patches 3-4 - Update driver to support changed DMA coherency model Patches 5-6 - adds TI K3 AM642x SoC platform data and so enable CPSW3g [1] https://www.ti.com/lit/pdf/spruim2 [2] https://patchwork.ozlabs.org/project/netdev/cover/20201130082046.16292-1-vigneshr@ti.com/ ==================== Link: https://lore.kernel.org/r/20210115192853.5469-1-grygorii.strashko@ti.comSigned-off-by:

Use the glue layer's functions to convert the dma_addr_t to and from CPPI5 address (with the ASEL bits), which should be used within the descriptors and data buffers. - Per channel coherency support The DMAs use the 'ASEL' bits to select data and configuration fetch path. The ASEL bits are placed at the unused parts of any address field used by the DMAs (pointers to descriptors, addresses in descriptors, ring base addresses). The ASEL is not part of the address (the DMAs can address 48bits). Individual channels can be configured to be coherent (via ACP port) or non coherent individually by configuring the ASEL to appropriate value.

For DMA API the DMA device should be used as cpsw does not accesses to descriptors or data buffers in any ways. The DMA does. Also, drop dma_coerce_mask_and_coherent() setting on CPSW device, as it should be done by DMA driver which does data movement. This is required for adding AM64x CPSW3g support where DMA coherency supported per DMA channel. Signed-off-by:

Update DT binding for recently introduced TI K3 AM642x SoC [1] which contains 3 port (2 external ports) CPSW3g module. The CPSW3g integrated in MAIN domain and can be configured in multi port or switch modes. The overall functionality and DT bindings are similar to other K3 CPSWxg versions, so DT binding changes are minimal: - reword description - add new compatible 'ti,am642-cpsw-nuss' - allow 2 external ports child nodes - add missed 'assigned-clock' props [1] https://www.ti.com/lit/pdf/spruim2Signed-off-by:

The CPTS clock is usually a clk-mux which allows to select CPTS reference clock by using 'assigned-clock-parents', 'assigned-clocks' DT properties. Also depending on integration the power-domains has to be specified to enable CPTS IP. Hence add 'assigned-clock-parents', 'assigned-clocks' and 'power-domains' properties to the CPTS DT bindings to avoid dtbs_check warnings: cpts@310d0000: 'assigned-clock-parents', 'assigned-clocks' do not match any of the regexes: 'pinctrl-[0-9]+' cpts@310d0000: 'power-domains' does not match any of the regexes: 'pinctrl-[0-9]+' Signed-off-by:

The previous test added an address with a specified metric and check if correspond route was created. I somehow added two logs for the same test. Remove the duplicated one. Reported-by:

sh_eth_close() does a synchronous power down of the device before marking it closed. Revert the order, to make sure the device is never marked opened while suspended. While at it, use pm_runtime_put() instead of pm_runtime_put_sync(), as there is no reason to do a synchronous power down.

Using skb_csum_is_sctp is a easier way to validate it's a SCTP CRC checksum offload packet, and yet it also makes ixgbevf support SCTP CRC checksum offload for UDP and GRE encapped packets, just as it does in igb driver. Signed-off-by:
