git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 updates from Will Deacon: "There's quite a lot of code here, but much of it is due to the addition of a new PMU driver as well as some arm64-specific selftests which is an area where we've traditionally been lagging a bit. In terms of exciting features, this includes support for the Memory Tagging Extension which narrowly missed 5.9, hopefully allowing userspace to run with use-after-free detection in production on CPUs that support it. Work is ongoing to integrate the feature with KASAN for 5.11. Another change that I'm excited about (assuming they get the hardware right) is preparing the ASID allocator for sharing the CPU page-table with the SMMU. Those changes will also come in via Joerg with the IOMMU pull. We do stray outside of our usual directories in a few places, mostly due to core changes required by MTE. Although much of this has been Acked, there were a couple of places where we unfortunately didn't get any review feedback. Other than that, we ran into a handful of minor conflicts in -next, but nothing that should post any issues. Summary: - Userspace support for the Memory Tagging Extension introduced by Armv8.5. Kernel support (via KASAN) is likely to follow in 5.11. - Selftests for MTE, Pointer Authentication and FPSIMD/SVE context switching. - Fix and subsequent rewrite of our Spectre mitigations, including the addition of support for PR_SPEC_DISABLE_NOEXEC. - Support for the Armv8.3 Pointer Authentication enhancements. - Support for ASID pinning, which is required when sharing page-tables with the SMMU. - MM updates, including treating flush_tlb_fix_spurious_fault() as a no-op. - Perf/PMU driver updates, including addition of the ARM CMN PMU driver and also support to handle CPU PMU IRQs as NMIs. - Allow prefetchable PCI BARs to be exposed to userspace using normal non-cacheable mappings. - Implementation of ARCH_STACKWALK for unwinding. - Improve reporting of unexpected kernel traps due to BPF JIT failure. - Improve robustness of user-visible HWCAP strings and their corresponding numerical constants. - Removal of TEXT_OFFSET. - Removal of some unused functions, parameters and prototypes. - Removal of MPIDR-based topology detection in favour of firmware description. - Cleanups to handling of SVE and FPSIMD register state in preparation for potential future optimisation of handling across syscalls. - Cleanups to the SDEI driver in preparation for support in KVM. - Miscellaneous cleanups and refactoring work" * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (148 commits) Revert "arm64: initialize per-cpu offsets earlier" arm64: random: Remove no longer needed prototypes arm64: initialize per-cpu offsets earlier kselftest/arm64: Check mte tagged user address in kernel kselftest/arm64: Verify KSM page merge for MTE pages kselftest/arm64: Verify all different mmap MTE options kselftest/arm64: Check forked child mte memory accessibility kselftest/arm64: Verify mte tag inclusion via prctl kselftest/arm64: Add utilities and a test to validate mte memory perf: arm-cmn: Fix conversion specifiers for node type perf: arm-cmn: Fix unsigned comparison to less than zero arm64: dbm: Invalidate local TLB when setting TCR_EL1.HD arm64: mm: Make flush_tlb_fix_spurious_fault() a no-op arm64: Add support for PR_SPEC_DISABLE_NOEXEC prctl() option arm64: Pull in task_stack_page() to Spectre-v4 mitigation code KVM: arm64: Allow patching EL2 vectors even with KASLR is not enabled arm64: Get rid of arm64_ssbd_state KVM: arm64: Convert ARCH_WORKAROUND_2 to arm64_get_spectre_v4_state() KVM: arm64: Get rid of kvm_arm_have_ssbd() KVM: arm64: Simplify handling of ARCH_WORKAROUND_2 ...
2020-10-12net: dsa: microchip: fix race conditionChristian Eggers1-7/+9
Between queuing the delayed work and finishing the setup of the dsa ports, the process may sleep in request_module() (via phy_device_create()) and the queued work may be executed prior to the switch net devices being registered. In ksz_mib_read_work(), a NULL dereference will happen within netof_carrier_ok(dp->slave). Not queuing the delayed work in ksz_init_mib_timer() makes things even worse because the work will now be queued for immediate execution (instead of 2000 ms) in ksz_mac_link_down() via dsa_port_link_register_of(). Call tree: ksz9477_i2c_probe() \--ksz9477_switch_register() \--ksz_switch_register() +--dsa_register_switch() | \--dsa_switch_probe() | \--dsa_tree_setup() | \--dsa_tree_setup_switches() | +--dsa_switch_setup() | | +--ksz9477_setup() | | | \--ksz_init_mib_timer() | | | |--/* Start the timer 2 seconds later. */ | | | \--schedule_delayed_work(&dev->mib_read, msecs_to_jiffies(2000)); | | \--__mdiobus_register() | | \--mdiobus_scan() | | \--get_phy_device() | | +--get_phy_id() | | \--phy_device_create() | | |--/* sleeping, ksz_mib_read_work() can be called meanwhile */ | | \--request_module() | | | \--dsa_port_setup() | +--/* Called for non-CPU ports */ | +--dsa_slave_create() | | +--/* Too late, ksz_mib_read_work() may be called beforehand */ | | \--port->slave = ... | ... | +--Called for CPU port */ | \--dsa_port_link_register_of() | \--ksz_mac_link_down() | +--/* mib_read must be initialized here */ | +--/* work is already scheduled, so it will be executed after 2000 ms */ | \--schedule_delayed_work(&dev->mib_read, 0); \-- /* here port->slave is setup properly, scheduling the delayed work should be safe */ Solution: 1. Do not queue (only initialize) delayed work in ksz_init_mib_timer(). 2. Only queue delayed work in ksz_mac_link_down() if init is completed. 3. Queue work once in ksz_switch_register(), after dsa_register_switch() has completed.

2020-10-11net: mscc: ocelot: offload VLAN mangle action to VCAP IS1Vladimir Oltean2-4/+40
The VCAP_IS1_ACT_VID_REPLACE_ENA action, from the VCAP IS1 ingress TCAM, changes the classified VLAN. We are only exposing this ability for switch ports that are under VLAN aware bridges. This is because in standalone ports mode and under a bridge with vlan_filtering=0, the ocelot driver configures the switch to operate as VLAN-unaware, so the classified VLAN is not derived from the 802.1Q header from the packet, but instead is always equal to the port-based VLAN ID of the ingress port. We _can_ still change the classified VLAN for packets when operating in this mode, but the end result will most likely be a drop, since both the ingress and the egress port need to be members of the modified VLAN. And even if we install the new classified VLAN into the VLAN table of the switch, the result would still not be as expected: we wouldn't see, on the output port, the modified VLAN tag, but the original one, even though the classified VLAN was indeed modified. This is because of how the hardware works: on egress, what is pushed to the frame is a "port tag", which gives us the following options: - Tag all frames with port tag (derived from the classified VLAN) - Tag all frames with port tag, except if the classified VLAN is 0 or equal to the native VLAN of the egress port - No port tag Needless to say, in VLAN-unaware mode we are disabling the port tag. Otherwise, the existing VLAN tag would be ignored, and a second VLAN tag (the port tag), holding the classified VLAN, would be pushed (instead of replacing the existing 802.1Q tag). This is definitely not what the user wanted when installing a "vlan modify" action. So it is simply not worth bothering with VLAN modify rules under other configurations except when the ports are fully VLAN-aware.

2020-10-11enetc: Migrate to PHYLINK and PCS_LYNXClaudiu Manoil7-166/+191
This is a methodical transition of the driver from phylib to phylink, following the guidelines from sfp-phylink.rst. The MAC register configurations based on interface mode were moved from the probing path to the mac_config() hook. MAC enable and disable commands (enabling Rx and Tx paths at MAC level) were also extracted and assigned to their corresponding phylink hooks. As part of the migration to phylink, the serdes configuration from the driver was offloaded to the PCS_LYNX module, introduced in commit 0da4c3d393e4 ("net: phy: add Lynx PCS module"), the PCS_LYNX module being a mandatory component required to make the enetc driver work with phylink.

Add an efficient ingress to ingress netns switch that can be used out of tc BPF programs in order to redirect traffic from host ns ingress into a container veth device ingress without having to go via CPU backlog queue [0]. For local containers this can also be utilized and path via CPU backlog queue only needs to be taken once, not twice. On a high level this borrows from ipvlan which does similar switch in __netif_receive_skb_core() and then iterates via another_round. This helps to reduce latency for mentioned use cases.

2020-10-10drivers/net/wan/hdlc_fr: Move the skb_headroom check out of fr_hard_headerXie He1-13/+17
Move the skb_headroom check out of fr_hard_header and into pvc_xmit. This has two benefits: 1. Originally we only do this check for skbs sent by users on Ethernet- emulating PVC devices. After the change we do this check for skbs sent on normal PVC devices, too. (Also add a comment to make it clear that this is only a protection against upper layers that don't take dev->needed_headroom into account. Such upper layers should be rare and I believe they should be fixed.) 2. After the change we can simplify the parameter list of fr_hard_header. We no longer need to use a pointer to pointers (skb_p) because we no longer need to replace the skb inside fr_hard_header.

2020-10-10net: dsa: rtl8366rb: Roof MTU for switchLinus Walleij3-5/+39
The MTU setting for this DSA switch is global so we need to keep track of the MTU set for each port, then as soon as any MTU changes, roof the MTU to the biggest common denominator and poke that into the switch MTU setting. To achieve this we need a per-chip-variant state container for the RTL8366RB to use for the RTL8366RB-specific stuff. Other SMI switches does seem to have per-port MTU setting capabilities.

When packets are received on the error queue, this function under net_ratelimit(): netif_err(priv, hw, net_dev, "Err FD status = 0x%08x\n"); does not get printed. Instead we only see: [ 3658.845592] net_ratelimit: 244 callbacks suppressed [ 3663.969535] net_ratelimit: 230 callbacks suppressed [ 3669.085478] net_ratelimit: 228 callbacks suppressed Enabling NETIF_MSG_HW fixes this issue, and we can see some information about the frame descriptors of packets.

git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can ==================== linux-can-fixes-for-5.9-20201008 The first patch is by Lucas Stach and fixes m_can driver by removing an erroneous call to m_can_class_suspend() in runtime suspend. Which causes the pinctrl state to get stuck on the "sleep" state, which breaks all CAN functionality on SoCs where this state is defined. The last two patches target the j1939 protocol: Cong Wang fixes a syzbot finding of an uninitialized variable in the j1939 transport protocol. I contribute a patch, that fixes the initialization of a same uninitialized variable in a different function. ==================== Signed-off-by: Jakub Kicinski <[email protected]>
