The minimal driver is chip independent and uses I2C bus for chip access. Its purpose is to support chassis management on systems equipped with Mellanox switch ASICs. For example from BMC (Board Management Controller) device. Expose a dummy netdev for each front panel port and implement basic ethtool operations to obtain QSFP/SFP module info through ethtool.

Currently, the receive function fails to handle records already decrypted by the device due to the commit mentioned below.

Today, tls_sw_recvmsg is capable of using asynchronous mode to handle application data TLS records. Moreover, it assumes that if the cipher can be handled asynchronously, then all packets will be processed asynchronously. However, this assumption is not always true. Specifically, for AES-GCM in TLS1.2, it causes data corruption, and breaks user applications. This patch fixes this problem by separating the async capability from the decryption operation result.

TLS device cannot use the sw context. This patch returns the original tls device write space handler and moves the sw/device specific portions to the relevant files. Also, we remove the write_space call for the tls_sw flow, because it handles partial records in its delayed tx work handler.

We were skipping the prepare phase which causes some problems with at least a couple of drivers: - mv88e6xxx chooses to skip programming VID = 0 with -EOPNOTSUPP in the prepare phase, but we would still try to force this VID since we would only call the commit phase and so we would get the driver to return -EINVAL instead - qca8k does not currently have a port_vlan_add() callback implemented, yet we would try to call that unconditionally leading to a NPD Fix both issues by conforming to the current model doing a prepare/commit phase, this makes us consistent throughout the code and assumptions.

Implement support for the XDP_REDIRECT action. The redirected frame is transmitted and confirmed on the regular Tx/Tx conf queues. Frame is marked with the "XDP" type in the software annotation, since it requires special treatment. We don't have good hardware support for TX batching, so the XDP_XMIT_FLUSH flag doesn't make a difference for now; ndo_xdp_xmit performs the actual Tx operation on the spot. Signed-off-by:

With more modes added the logic in cake_select_tin() was getting a bit hairy, and it turns out we can actually simplify it quite a bit. This also allows us to get rid of one of the two diffserv parsing functions, which has the added benefit that already-zeroed DSCP fields won't get re-written. Suggested-by:

Add flag 'FWMARK' to enable use of firewall connmarks as tin selector. The connmark (skbuff->mark) needs to be in the range 1->tin_cnt ie. for diffserv3 the mark needs to be 1->3. Background Typically CAKE uses DSCP as the basis for tin selection. DSCP values are relatively easily changed as part of the egress path, usually with iptables & the mangle table, ingress is more challenging. CAKE is often used on the WAN interface of a residential gateway where passthrough of DSCP from the ISP is either missing or set to unhelpful values thus use of ingress DSCP values for tin selection isn't helpful in that environment. An approach to solving the ingress tin selection problem is to use CAKE's understanding of tc filters. Naive tc filters could match on source/destination port numbers and force tin selection that way, but multiple filters don't scale particularly well as each filter must be traversed whether it matches or not. e.g. a simple example to map 3 firewall marks to tins: MAJOR=$( tc qdisc show dev $DEV | head -1 | awk '{print $3}' ) tc filter add dev $DEV parent $MAJOR protocol all handle 0x01 fw action skbedit priority ${MAJOR}1 tc filter add dev $DEV parent $MAJOR protocol all handle 0x02 fw action skbedit priority ${MAJOR}2 tc filter add dev $DEV parent $MAJOR protocol all handle 0x03 fw action skbedit priority ${MAJOR}3 Another option is to use eBPF cls_act with tc filters e.g. MAJOR=$( tc qdisc show dev $DEV | head -1 | awk '{print $3}' ) tc filter add dev $DEV parent $MAJOR bpf da obj my-bpf-fwmark-to-class.o This has the disadvantages of a) needing someone to write & maintain the bpf program, b) a bpf toolchain to compile it and c) needing to hardcode the major number in the bpf program so it matches the cake instance (or forcing the cake instance to a particular major number) since the major number cannot be passed to the bpf program via tc command line. As already hinted at by the previous examples, it would be helpful to associate tins with something that survives the Internet path and ideally allows tin selection on both egress and ingress. Netfilter's conntrack permits setting an identifying mark on a connection which can also be restored to an ingress packet with tc action connmark e.g. tc filter add dev eth0 parent ffff: protocol all prio 10 u32 \ match u32 0 0 flowid 1:1 action connmark action mirred egress redirect dev ifb1 Since tc's connmark action has restored any connmark into skb->mark, any of the previous solutions are based upon it and in one form or another copy that mark to the skb->priority field where again CAKE picks this up. This change cuts out at least one of the (less intuitive & non-scalable) middlemen and permit direct access to skb->mark. Signed-off-by: -

CAKE host fairness does not work well with TCP flows in dual-srchost and dual-dsthost setup. The reason is that ACKs generated by TCP flows are classified as sparse flows, and affect flow isolation from other hosts. Fix this by calculating host_load based only on the bulk flows a host generates. In a hash collision the host_bulk_flow_count values must be decremented on the old hosts and incremented on the new ones *if* the queue is in the bulk set. Reported-by:

Harini Katakam authored
When macb device is suspended and system is powered down, the clocks are removed and hence macb should be closed gracefully and restored upon resume. This patch does the same by switching off the net device, suspending phy and performing necessary cleanup of interrupts and BDs. Upon resume, all these are reinitialized again. Reset of macb device is done only when GEM is not a wake device. Even when gem is a wake device, tx queues can be stopped and ptp device can be closed (tsu clock will be disabled in pm_runtime_suspend) as wake event detection has no dependency on this.

Pablo Neira Ayuso says: ==================== Netfilter/IPVS updates for net-next The following patchset contains Netfilter/IPVS updates for net-next: 1) Add .release_ops to properly unroll .select_ops, use it from nft_compat. After this change, we can remove list of extensions too to simplify this codebase. 2) Update amanda conntrack helper to support v3.4, from Florian Tham. 3) Get rid of the obsolete BUGPRINT macro in ebtables, from Florian Westphal. 4) Merge IPv4 and IPv6 masquerading infrastructure into one single module. From Florian Westphal. 5) Patchset to remove nf_nat_l3proto structure to get rid of indirections, from Florian Westphal. 6) Skip unnecessary conntrack timeout updates in case the value is still the same, also from Florian Westphal. 7) Remove unnecessary 'fall through' comments in empty switch cases, from Li RongQing. 8) Fix lookup to fixed size hashtable sets on big endian with 32-bit keys. 9) Incorrect logic to deactivate path of fixed size hashtable sets, element was being tested to self. 10) Remove nft_hash_key(), the bitmap set is always selected for 16-bit keys. 11) Use boolean whenever possible in IPVS codebase, from Andrea Claudi. 12) Enter close state in conntrack if RST matches exact sequence number, from Florian Westphal. 13) Initialize dst_cache in tunnel extension, from wenxu. 14) Pass protocol as u16 to xt_check_match and xt_check_target, from Li RongQing. 15) SCTP header is granted to be in a linear area from IPVS NAT handler, from Xin Long. 16) Don't steal packets coming from slave VRF device from the ip_sabotage_in() path, from David Ahern. 17) Fix unsafe update of basechain stats, from Li RongQing. 18) Make sure CONNTRACK_LOCKS is power of 2 to let compiler optimize modulo operation as bitwise AND, from Li RongQing. 19) Use device_attribute instead of internal definition in the IDLETIMER target, from Sami Tolvanen. 20) Merge redir, masq and IPv4/IPv6 NAT chain types, from Florian Westphal. ==================== Signed-off-by: -

This adds the support of enabling MT7663U and MT7668U Bluetooth function running on the top of btmtkuart driver. There are a few differences between MT766[3,8]U and MT7622 where MT766[3,8]U are standalone devices based on UART transport while MT7622 bluetooth is a built-in device on MediaTek SoC communicating with the host through BTIF serial transport. Thus, extra setup sequence is necessary for these standalone devices such as remote regulator and reset control via GPIO, baud rate changing handshake between the host and device and so on.
