2022-05-19xen/scsifront: harden driver against malicious backendJuergen Gross
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.

2022-05-19x86/boot: Wrap literal addresses in absolute_pointer()Kees Cook
GCC 11 (incorrectly[1]) assumes that literal values cast to (void *) should be treated like a NULL pointer with an offset, and raises diagnostics when doing bounds checking under -Warray-bounds. GCC 12 got "smarter" about finding these: In function 'rdfs8', inlined from 'vga_recalc_vertical' at /srv/code/arch/x86/boot/video-mode.c:124:29, inlined from 'set_mode' at /srv/code/arch/x86/boot/video-mode.c:163:3: /srv/code/arch/x86/boot/boot.h:114:9: warning: array subscript 0 is outside array bounds of 'u8[0]' {aka 'unsigned char[]'} [-Warray-bounds] 114 | asm volatile("movb %%fs:%1,%0" : "=q" (v) : "m" (*(u8 *)addr)); | ^~~ This has been solved in other places[2] already by using the recently added absolute_pointer() macro.

2022-05-19tls: Add opt-in zerocopy mode of sendfile()Boris Pismenny
TLS device offload copies sendfile data to a bounce buffer before transmitting. It allows to maintain the valid MAC on TLS records when the file contents change and a part of TLS record has to be retransmitted on TCP level. In many common use cases (like serving static files over HTTPS) the file contents are not changed on the fly. In many use cases breaking the connection is totally acceptable if the file is changed during transmission, because it would be received corrupted in any case. This commit allows to optimize performance for such use cases to providing a new optional mode of TLS sendfile(), in which the extra copy is skipped. Removing this copy improves performance significantly, as TLS and TCP sendfile perform the same operations, and the only overhead is TLS header/trailer insertion. The new mode can only be enabled with the new socket option named TLS_TX_ZEROCOPY_SENDFILE on per-socket basis. It preserves backwards compatibility with existing applications that rely on the copying behavior. The new mode is safe, meaning that unsolicited modifications of the file being sent can't break integrity of the kernel. The worst thing that can happen is sending a corrupted TLS record, which is in any case not forbidden when using regular TCP sockets. Sockets other than TLS device offload are not affected by the new socket option. The actual status of zerocopy sendfile can be queried with sock_diag.

2022-05-19thermal: k3_j72xx_bandgap: Add the bandgap driver supportKeerthy
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.

When removing short term pins, I've changed the the batch buffer pinning for relocation to use __i915_vma_pin, because i915_gem_object_ggtt_pin_ww was destroying the old vma.

2022-05-19drm/i915: Fix CFI violation with show_dynamic_id()Nathan Chancellor
When an attribute group is created with sysfs_create_group(), the ->sysfs_ops() callback is set to kobj_sysfs_ops, which sets the ->show() callback to kobj_attr_show(). kobj_attr_show() uses container_of() to get the ->show() callback from the attribute it was passed, meaning the ->show() callback needs to be the same type as the ->show() callback in 'struct kobj_attribute'. However, show_dynamic_id() has the type of the ->show() callback in 'struct device_attribute', which causes a CFI violation when opening the 'id' sysfs node under drm/card0/metrics. This happens to work because the layout of 'struct kobj_attribute' and 'struct device_attribute' are the same, so the container_of() cast happens to allow the ->show() callback to still work. Change the type of show_dynamic_id() to match the ->show() callback in 'struct kobj_attributes' and update the type of sysfs_metric_id to match, which resolves the CFI violation.

2022-05-19net: bridge: Clear offload_fwd_mark when passing frame up bridge interface.Andrew Lunn
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().
