kobject_init_and_add() takes reference even when it fails. If this function returns an error, kobject_put() must be called to properly clean up the memory associated with the object.

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2020-05-26 Updates highlights: 1) From Vu Pham (8): Support VM traffics failover with bonded VF representors and e-switch egress/ingress ACLs This series introduce the support for Virtual Machine running I/O traffic over direct/fast VF path and failing over to slower paravirtualized path using the following features: __________________________________ | VM _________________ | | |FAILOVER device | | | |________________| | | | | | ____|_____ | | | | | | ______ |___ ____|_______ | | | VF PT | |VIRTIO-NET | | | | device | | device | | | |_________| |___________| | |___________|______________|________| | | | HYPERVISOR | | ____|______ | | macvtap | | |virtio BE | | |___________| | | | ____|_____ | |host VF | | |_________| | | _____|______ _____|_____ | PT VF | | host VF | |representor| |representor| |___________| |___________| \ / \ / \ / \ / _________________ \_______/ | | _______|________ | V-SWITCH | |VF representors |________________| (OVS) | | bond | |________________| |________________| | ________|________ | Uplink | | representor | |_________________| Summary: -------- Problem statement: ------------------ Currently in above topology, when netfailover device is configured using VFs and eswitch VF representors, and when traffic fails over to stand-by VF which is exposed using macvtap device to guest VM, eswitch fails to switch the traffic to the stand-by VF representor. This occurs because there is no knowledge at eswitch level of the stand-by representor device. Solution: --------- Using standard bonding driver, a bond netdevice is created over VF representor device which is used for offloading tc rules. Two VF representors are bonded together, one for the passthrough VF device and another one for the stand-by VF device. With this solution, mlx5 driver listens to the failover events occuring at the bond device level to failover traffic to either of the active VF representor of the bond. a. VM with netfailover device of VF pass-thru (PT) device and virtio-net paravirtualized device with same MAC-address to handle failover traffics at VM level. b. Host bond is active-standby mode, with the lower devices being the VM VF PT representor, and the representor of the 2nd VF to handle failover traffics at Hypervisor/V-Switch OVS level. - During the steady state (fast datapath): set the bond active device to be the VM PT VF representor. - During failover: apply bond failover to the second VF representor device which connects to the VM non-accelerated path. c. E-Switch ingress/egress ACL tables to support failover traffics at E-Switch level I. E-Switch egress ACL with forward-to-vport rule: - By default, eswitch vport egress acl forward packets to its counterpart NIC vport. - During port failover, the egress acl forward-to-vport rule will be added to e-switch vport of passive/in-active slave VF representor to forward packets to other e-switch vport ie. the active slave representor's e-switch vport to handle egress "failover" traffics. - Using lower change netdev event to detect a representor is a lower dev (slave) of bond and becomes active, adding egress acl forward-to-vport rule of all other slave netdevs to forward to this representor's vport. - Using upper change netdev event to detect a representor unslaving from bond device to delete its vport's egress acl forward-to-vport rule. II. E-Switch ingress ACL metadata reg_c for match - Bonded representors' vorts sharing tc block have the same root ingress acl table and a unique metadata for match. - Traffics from both representors's vports will be tagged with same unique metadata reg_c. - Using upper change netdev event to detect a representor enslaving/unslaving from bond device to setup shared root ingress acl and unique metadata. 2) From Alex Vesker (2): Slpit RX and TX lock for parallel rule insertion in software steering 3) Eli Britstein (2): Optimize performance for IPv4/IPv6 ethertype use the HW ip_version register rather than parsing eth frames for ethertype. ==================== Signed-off-by: David S.

Connectivity Disruption Indication For Internet Protocol version 6 (IPv6) [RFC2460], the counterpart of the ICMP destination unreachable message of code 0 (net unreachable) and of code 1 (host unreachable) is the ICMPv6 destination unreachable message of code 0 (no route to destination) [RFC4443]. As with IPv4, a router should generate an ICMPv6 destination unreachable message of code 0 in response to a packet that cannot be delivered to its destination address because it lacks a matching entry in its routing table.

2020-05-28net: dsa: sja1105: offload the Credit-Based Shaper qdiscVladimir Oltean
SJA1105, being AVB/TSN switches, provide hardware assist for the Credit-Based Shaper as described in the IEEE 8021Q-2018 document. First generation has 10 shapers, freely assignable to any of the 4 external ports and 8 traffic classes, and second generation has 16 shapers. The Credit-Based Shaper tables are accessed through the dynamic reconfiguration interface, so we have to restore them manually after a switch reset. The tables are backed up by the static config only on P/Q/R/S, and we don't want to add custom code only for that family, since the procedure that is in place now works for both. Tested with the following commands: data_rate_kbps=67000 port_transmit_rate_kbps=1000000 idleslope=$data_rate_kbps sendslope=$(($idleslope - $port_transmit_rate_kbps)) locredit=$((-0x80000000)) hicredit=$((0x7fffffff)) tc qdisc add dev swp2 root handle 1: mqprio hw 0 num_tc 8 \ map 0 1 2 3 4 5 6 7 \ queues 1@0 1@1 1@2 1@3 1@4 1@5 1@6 1@7 tc qdisc replace dev swp2 parent 1:1 cbs \ idleslope $idleslope \ sendslope $sendslope \ hicredit $hicredit \ locredit $locredit \ offload 1 Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S.

2020-05-28mt76: fix wcid allocation issuesFelix Fietkau
mt76 core uses ffs() to find the next free bit. This works well for 32 bit architectures where BITS_PER_LONG is 32. ffs only checks 32 bit values, so allocation fails on 64 bit architectures. Additionally, the wcid mask array was too small in cases where the array was not a multiple of BITS_PER_LONG. Fix this by making the wcid mask array u32 instead and use DIV_ROUND_UP for the size, just in case we ever bump it to a value that's not a multiple of 32.

2020-05-28powerpc/bpf: Enable bpf_probe_read{, str}() on powerpc againPetr Mladek
The commit 0ebeea8ca8a4d1d453a ("bpf: Restrict bpf_probe_read{, str}() only to archs where they work") caused that bpf_probe_read{, str}() functions were not longer available on architectures where the same logical address might have different content in kernel and user memory mapping. These architectures should use probe_read_{user,kernel}_str helpers. For backward compatibility, the problematic functions are still available on architectures where the user and kernel address spaces are not overlapping. This is defined CONFIG_ARCH_HAS_NON_OVERLAPPING_ADDRESS_SPACE. At the moment, these backward compatible functions are enabled only on x86_64, arm, and arm64. Let's do it also on powerpc that has the non overlapping address space as well.

2020-05-28arm64/kernel: Fix return value when cpu_online() fails in __cpu_up()Nobuhiro Iwamatsu
If boot_secondary() was successful, and cpu_online() was an error in __cpu_up(), -EIO was returned, but 0 is returned by commit d22b115cbfbb7 ("arm64/kernel: Simplify __cpu_up() by bailing out early"). Therefore, bringup_wait_for_ap() causes the primary core to wait for a long time, which may cause boot failure. This commit sets -EIO to return code under the same conditions.
