2022-05-19xen/scsifront: harden driver against malicious backendJuergen Gross1-28/+76
Instead of relying on a well behaved PV scsi backend verify all meta data received from the backend and avoid multiple reads of the same data from the shared ring page. In case any illegal data from the backend is detected switch the PV device to a new "error" state and deactivate it for further use. Use the "lateeoi" variant for the event channel in order to avoid event storms blocking the guest.

2022-05-19thermal: k3_j72xx_bandgap: Add the bandgap driver supportKeerthy2-1/+567
Add VTM thermal support. In the Voltage Thermal Management Module(VTM), K3 J72XX supplies a voltage reference and a temperature sensor feature that are gathered in the band gap voltage and temperature sensor (VBGAPTS) module. The band gap provides current and voltage reference for its internal circuits and other analog IP blocks. The analog-to-digital converter (ADC) produces an output value that is proportional to the silicon temperature. Currently reading temperatures only is supported. There are no active/passive cooling agent supported. J721e SoCs have errata i2128: https://www.ti.com/lit/pdf/sprz455 The VTM Temperature Monitors (TEMPSENSORs) are trimmed during production, with the resulting values stored in software-readable registers. Software should use these register values when translating the Temperature Monitor output codes to temperature values. It has an involved workaround. Software needs to read the error codes for -40C, 30C, 125C from the efuse for each device & derive a new look up table for adc to temperature conversion. Involved calculating slopes & constants using 3 different straight line equations with adc refernce codes as the y-axis & error codes in the x-axis. -40C to 30C 30C to 125C 125C to 150C With the above 2 line equations we derive the full look-up table to workaround the errata i2128 for j721e SoC.

2022-05-19net: bridge: Clear offload_fwd_mark when passing frame up bridge interface.Andrew Lunn1-0/+7
It is possible to stack bridges on top of each other. Consider the following which makes use of an Ethernet switch: br1 / \ / \ / \ br0.11 wlan0 | br0 / | \ p1 p2 p3 br0 is offloaded to the switch. Above br0 is a vlan interface, for vlan 11. This vlan interface is then a slave of br1. br1 also has a wireless interface as a slave. This setup trunks wireless lan traffic over the copper network inside a VLAN. A frame received on p1 which is passed up to the bridge has the skb->offload_fwd_mark flag set to true, indicating that the switch has dealt with forwarding the frame out ports p2 and p3 as needed. This flag instructs the software bridge it does not need to pass the frame back down again. However, the flag is not getting reset when the frame is passed upwards. As a result br1 sees the flag, wrongly interprets it, and fails to forward the frame to wlan0. When passing a frame upwards, clear the flag. This is the Rx equivalent of br_switchdev_frame_unmark() in br_dev_xmit().

2022-05-18ptp: ocp: change sysfs attr group handlingJonathan Lemon1-15/+42
In the detach path, the driver calls sysfs_remove_group() for the groups it believes has been registered. However, if the group was never previously registered, then this causes a splat. Instead, compute the groups that should be registered in advance, and then call sysfs_create_groups(), which registers them all at once. Update the error handling appropriately.

Pablo Neira Ayuso says: ==================== Netfilter fixes for net 1) Reduce number of hardware offload retries from flowtable datapath which might hog system with retries, from Felix Fietkau. 2) Skip neighbour lookup for PPPoE device, fill_forward_path() already provides this and set on destination address from fill_forward_path for PPPoE device, also from Felix. 4) When combining PPPoE on top of a VLAN device, set info->outdev to the PPPoE device so software offload works, from Felix. 5) Fix TCP teardown flowtable state, races with conntrack gc might result in resetting the state to ESTABLISHED and the time to one day. Joint work with Oz Shlomo and Sven Auhagen. 6) Call dst_check() from flowtable datapath to check if dst is stale instead of doing it from garbage collector path. 7) Disable register tracking infrastructure, either user-space or kernel need to pre-fetch keys inconditionally, otherwise register tracking assumes data is already available in register that might not well be there, leading to incorrect reductions. * git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf: netfilter: nf_tables: disable expression reduction infra netfilter: flowtable: move dst_check to packet path netfilter: flowtable: fix TCP flow teardown netfilter: nft_flow_offload: fix offload with pppoe + vlan net: fix dev_fill_forward_path with pppoe + bridge netfilter: nft_flow_offload: skip dst neigh lookup for ppp devices netfilter: flowtable: fix excessive hw offload attempts after failure ==================== Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Jakub Kicinski <[email protected]>
