The mask for the RSRC_GRP field in the INIT_RSRC_GRP endpoint initialization register is incorrectly defined for IPA v4.2 (where it is only one bit wide). So we need to fix this. The fix is not straightforward, however. Field masks are passed to functions like u32_encode_bits(), and for that they must be constant. To address this, we define a new inline function that returns the *encoded* value to use for a given RSRC_GRP field, which depends on the IPA version. The caller can then use something like this, to assign a given endpoint resource id 1: u32 offset = IPA_REG_ENDP_INIT_RSRC_GRP_N_OFFSET(endpoint_id); u32 val = rsrc_grp_encoded(ipa->version, 1); iowrite32(val, ipa->reg_virt + offset); The next patch requires this fix.

At the end of ipa_mem_setup() we write the local packet processing context base register to tell it where the processing context memory is. But we are writing the wrong value. The value written turns out to be the offset of the modem header memory region (assigned earlier in the function). Fix this bug.

The Finisar FCLF8520P2BTL 1000BaseT SFP module uses a Marvel 88E1111 PHY with a modified PHY ID. Add support for this ID using the 88E1111 methods. By default these modules do not have 1000BaseX auto-negotiation enabled, which is not generally desirable with Linux networking drivers. Add handling to enable 1000BaseX auto-negotiation when these modules are used in 1000BaseX mode. Also, some special handling is required to ensure that 1000BaseT auto-negotiation is enabled properly when desired.

Xin Long says: ==================== sctp: Implement RFC6951: UDP Encapsulation of SCTP Description From the RFC: The Main Reasons: o To allow SCTP traffic to pass through legacy NATs, which do not provide native SCTP support as specified in [BEHAVE] and [NATSUPP]. o To allow SCTP to be implemented on hosts that do not provide direct access to the IP layer. In particular, applications can use their own SCTP implementation if the operating system does not provide one. Implementation Notes: UDP-encapsulated SCTP is normally communicated between SCTP stacks using the IANA-assigned UDP port number 9899 (sctp-tunneling) on both ends. There are circumstances where other ports may be used on either end, and it might be required to use ports other than the registered port. Each SCTP stack uses a single local UDP encapsulation port number as the destination port for all its incoming SCTP packets, this greatly simplifies implementation design. An SCTP implementation supporting UDP encapsulation MUST maintain a remote UDP encapsulation port number per destination address for each SCTP association. Again, because the remote stack may be using ports other than the well-known port, each port may be different from each stack. However, because of remapping of ports by NATs, the remote ports associated with different remote IP addresses may not be identical, even if they are associated with the same stack. Because the well-known port might not be used, implementations need to allow other port numbers to be specified as a local or remote UDP encapsulation port number through APIs. Patches: This patchset is using the udp4/6 tunnel APIs to implement the UDP Encapsulation of SCTP with not much change in SCTP protocol stack and with all current SCTP features keeped in Linux Kernel. 1 - 4: Fix some UDP issues that may be triggered by SCTP over UDP. 5 - 7: Process incoming UDP encapsulated packets and ICMP packets. 8 -10: Remote encap port's update by sysctl, sockopt and packets. 11-14: Process outgoing pakects with UDP encapsulated and its GSO. 15-16: Add the part from draft-tuexen-tsvwg-sctp-udp-encaps-cons-03. 17: Enable this feature. Tests: - lksctp-tools/src/func_tests with UDP Encapsulation enabled/disabled: Both make v4test and v6test passed. - sctp-tests with UDP Encapsulation enabled/disabled: repeatability/procdumps/sctpdiag/gsomtuchange/extoverflow/ sctphashtable passed. Others failed as expected due to those "iptables -p sctp" rules. - netperf on lo/netns/virtio_net, with gso enabled/disabled and with ip_checksum enabled/disabled, with UDP Encapsulation enabled/disabled: No clear performance dropped. v1->v2: - Fix some incorrect code in the patches 5,6,8,10,11,13,14,17, suggested by Marcelo. - Append two patches 15-16 to add the Additional Considerations for UDP Encapsulation of SCTP from draft-tuexen-tsvwg-sctp-udp-encaps-cons-03. v2->v3: - remove the cleanup code in patch 2, suggested by Willem. - remove the patch 3 and fix the checksum in the new patch 3 after talking with Paolo, Marcelo and Guillaume. - add 'select NET_UDP_TUNNEL' in patch 4 to solve a compiling error. - fix __be16 type cast warning in patch 8. - fix the wrong endian orders when setting values in 14,16. v3->v4: - add entries in ip-sysctl.rst in patch 7,16, as Marcelo Suggested. - not create udp socks when udp_port is set to 0 in patch 16, as Marcelo noticed. v4->v5: - improve the description for udp_port and encap_port entries in patch 7, 16. - use 0 as the default udp_port. ==================== Link: https://lore.kernel.org/r/cover.1603955040.git.lucien.xin@gmail.comSigned-off-by: Jakub Kicinski <kuba@kernel.org>

This patch is to enable udp tunneling socks by calling sctp_udp_sock_start() in sctp_ctrlsock_init(), and sctp_udp_sock_stop() in sctp_ctrlsock_exit(). Also add sysctl udp_port to allow changing the listening sock's port by users. Wit this patch, the whole sctp over udp feature can be enabled and used. v1->v2: - Also update ctl_sock udp_port in proc_sctp_do_udp_port() where netns udp_port gets changed. v2->v3: - Call htons() when setting sk udp_port from netns udp_port. v3->v4: - Not call sctp_udp_sock_start() when new_value is 0. - Add udp_port entry in ip-sysctl.rst. v4->v5: - Not call sctp_udp_sock_start/stop() in sctp_ctrlsock_init/exit(). - Improve the description of udp_port in ip-sysctl.rst.

This one basically does the similar things in sctp_v6_xmit as does for udp4 sock in the last patch, just note that: 1. label needs to be calculated, as it's the param of udp_tunnel6_xmit_skb(). 2.

This patch does what the rfc6951#section-5.3 says for ipv4: "Within the UDP header, the source port MUST be the local UDP encapsulation port number of the SCTP stack, and the destination port MUST be the remote UDP encapsulation port number maintained for the association and the destination address to which the packet is sent (see Section 5.1). Because the SCTP packet is the UDP payload, the length of the UDP packet MUST be the length of the SCTP packet plus the size of the UDP header. The SCTP checksum MUST be computed for IPv4 and IPv6, and the UDP checksum SHOULD be computed for IPv4 and IPv6." Some places need to be adjusted in sctp_packet_transmit(): 1. For non-gso packets, when transport's encap_port is set, sctp checksum has to be done in sctp_packet_pack(), as the outer udp will use ip_summed = CHECKSUM_PARTIAL to do the offload setting for checksum. 2. Delay calling dst_clone() and skb_dst_set() for non-udp packets until sctp_v4_xmit(), as for udp packets, skb_dst_set() is not needed before calling udp_tunnel_xmit_skb(). then in sctp_v4_xmit(): 1. Go to udp_tunnel_xmit_skb() only when transport->encap_port and net->sctp.udp_port both are set, as these are one for dst port and another for src port. 2. For gso packet, SKB_GSO_UDP_TUNNEL_CSUM is set for gso_type, and with this udp checksum can be done in __skb_udp_tunnel_segment() for each segments after the sctp gso. 3. inner_mac_header and inner_transport_header are set, as these will be needed in __skb_udp_tunnel_segment() to find the right headers. 4. df and ttl are calculated, as these are the required params by udp_tunnel_xmit_skb(). 5. nocheck param has to be false, as "the UDP checksum SHOULD be computed for IPv4 and IPv6", says in rfc6951#section-5.3. v1->v2: - Use sp->udp_port instead in sctp_v4_xmit(), which is more safe.

sctp_mtu_payload() is for calculating the frag size before making chunks from a msg. So we should only add udphdr size to overhead when udp socks are listening, as only then sctp can handle the incoming sctp over udp packets and outgoing sctp over udp packets will be possible. Note that we can't do this according to transport->encap_port, as different transports may be set to different values, while the chunks were made before choosing the transport, we could not be able to meet all rfc6951#section-5.6 recommends. v1->v2: - Add udp_port for sctp_sock to avoid a potential race issue, it will be used in xmit path in the next patch.

As rfc6951#section-5.4 says: "After finding the SCTP association (which includes checking the verification tag), the UDP source port MUST be stored as the encapsulation port for the destination address the SCTP packet is received from (see Section 5.1). When a non-encapsulated SCTP packet is received by the SCTP stack, the encapsulation of outgoing packets belonging to the same association and the corresponding destination address MUST be disabled." transport encap_port should be updated by a validated incoming packet's udp src port. We save the udp src port in sctp_input_cb->encap_port, and then update the transport in two places: 1. right after vtag is verified, which is required by RFC, and this allows the existent transports to be updated by the chunks that can only be processed on an asoc. 2. right before processing the 'init' where the transports are added, and this allows building a sctp over udp connection by client with the server not knowing the remote encap port. 3. when processing ootb_pkt and creating the temporary transport for the reply pkt. Note that sctp_input_cb->header is removed, as it's not used any more in sctp. v1->v2: - Change encap_port as __be16 for sctp_input_cb.

encap_port is added as per netns/sock/assoc/transport, and the latter one's encap_port inherits the former one's by default. The transport's encap_port value would mostly decide if one packet should go out with udp encapsulated or not.

As it says in rfc6951#section-5.5: "When receiving ICMP or ICMPv6 response packets, there might not be enough bytes in the payload to identify the SCTP association that the SCTP packet triggering the ICMP or ICMPv6 packet belongs to. If a received ICMP or ICMPv6 packet cannot be related to a specific SCTP association or the verification tag cannot be verified, it MUST be discarded silently. In particular, this means that the SCTP stack MUST NOT rely on receiving ICMP or ICMPv6 messages. Implementation constraints could prevent processing received ICMP or ICMPv6 messages." ICMP or ICMPv6 packets need to be handled, and this is implemented by udp encap sock .encap_err_lookup function. The .encap_err_lookup function is called in __udp(6)_lib_err_encap() to confirm this path does need to be updated. For sctp, what we can do here is check if the corresponding asoc and transport exist. Note that icmp packet process for sctp over udp is done by udp sock .encap_err_lookup(), and it means for now we can't do as much as sctp_v4/6_err() does. Also we can't do the two mappings mentioned in rfc6951#section-5.5.

This patch is to add the functions to create/release udp4 sock, and set the sock's encap_rcv to process the incoming udp encap sctp packets. In sctp_udp_rcv(), as we can see, all we need to do is fix the transport header for sctp_rcv(), then it would implement the part of rfc6951#section-5.4: "When an encapsulated packet is received, the UDP header is removed. Then, the generic lookup is performed, as done by an SCTP stack whenever a packet is received, to find the association for the received SCTP packet" Note that these functions will be called in the last patch of this patchset when enabling this feature. v1->v2: - Add pr_err() when fails to create udp v4 sock. v2->v3: - Add 'select NET_UDP_TUNNEL' in sctp Kconfig. v3->v4: - No change. v4->v5: - Change to set udp_port to 0 by default.

For the gso of sctp over udp packets, sctp_gso_segment() will be called in skb_udp_tunnel_segment(), we need to set transport_header to sctp header. As all the current HWs can't handle both crc checksum and udp checksum at the same time, the crc checksum has to be done in sctp_gso_segment() by removing the NETIF_F_SCTP_CRC flag from the features. Meanwhile, if the HW can't do udp checksum, csum and csum_start has to be set correctly, and udp checksum will be done in __skb_udp_tunnel_segment() by calling gso_make_checksum(). Thanks to Paolo, Marcelo and Guillaume for helping with this one. v1->v2: - no change. v2->v3: - remove the he NETIF_F_SCTP_CRC flag from the features. - set csum and csum_start in sctp_gso_make_checksum().

For some protocol's gso, like SCTP, it's using GSO_BY_FRAGS for gso_size. When using UDP to encapsulate its packet, it will return error in udp6_ufo_fragment() as skb->len < gso_size, and it will never go to the gso tunnel processing. So we should move this check after udp gso tunnel processing, the same as udp4_ufo_fragment() does. v1->v2: - no change. v2->v3: - not do any cleanup.

There is a chance that __udp4/6_lib_lookup() returns a udp encap sock in __udp_lib_err(), like the udp encap listening sock may use the same port as remote encap port, in which case it should go to __udp4/6_lib_err_encap() for more validation before processing the icmp packet.

DSA assumes that a bridge which has vlan filtering disabled is not vlan aware, and ignores all vlan configuration. However, the kernel software bridge code allows configuration in this state. This causes the kernel's idea of the bridge vlan state and the hardware state to disagree, so "bridge vlan show" indicates a correct configuration but the hardware lacks all configuration. Even worse, enabling vlan filtering on a DSA bridge immediately blocks all traffic which, given the output of "bridge vlan show", is very confusing. Allow the VLAN configuration to be updated on Marvell DSA bridges, otherwise we end up cutting all traffic when enabling vlan filtering.
