Indirect Target Selection (ITS) is a bug in some pre-ADL Intel CPUs with eIBRS. It affects prediction of indirect branch and RETs in the lower half of cacheline. Due to ITS such branches may get wrongly predicted to a target of (direct or indirect) branch that is located in the upper half of the cacheline. Scope of impact =============== Guest/host isolation -------------------- When eIBRS is used for guest/host isolation, the indirect branches in the VMM may still be predicted with targets corresponding to branches in the guest. Intra-mode ---------- cBPF or other native gadgets can be used for intra-mode training and disclosure using ITS. User/kernel isolation --------------------- When eIBRS is enabled user/kernel isolation is not impacted. Indirect Branch Prediction Barrier (IBPB) ----------------------------------------- After an IBPB, indirect branches may be predicted with targets corresponding to direct branches which were executed prior to IBPB. This is mitigated by a microcode update. Add cmdline parameter indirect_target_selection=off|on|force to control the mitigation to relocate the affected branches to an ITS-safe thunk i.e. located in the upper half of cacheline. Also add the sysfs reporting. When retpoline mitigation is deployed, ITS safe-thunks are not needed, because retpoline sequence is already ITS-safe. Similarly, when call depth tracking (CDT) mitigation is deployed (retbleed=stuff), ITS safe return thunk is not used, as CDT prevents RSB-underflow. To not overcomplicate things, ITS mitigation is not supported with spectre-v2 lfence;jmp mitigation. Moreover, it is less practical to deploy lfence;jmp mitigation on ITS affected parts anyways.

The version in the sysfs attribute should correspond to the version in
which this is enabled and visible for end users. It usually doesn't
correspond to the version in which the patch was developed, but rather a
release that will contain it. Update them to 6.15.

The driver hid-appletb-kbd was upstreamed in kernel 6.15. But, due to an oversight on my part, I didn't change the kernel version and expected date while upstreaming the driver, thus it remained as 6.5, the original kernel version when the driver was developed for downstream. This commit should fix this. Signed-off-by: Aditya Garg <gargaditya08@live.com> Signed-off-by: Jiri Kosina <jkosina@suse.com>

The ufs device JEDEC specification version 4.1 adds support for the device level exception events. To support this new device level exception feature, expose two new sysfs nodes below to provide the user space access to the device level exception information. /sys/bus/platform/drivers/ufshcd/*/device_lvl_exception_count /sys/bus/platform/drivers/ufshcd/*/device_lvl_exception_id The device_lvl_exception_count sysfs node reports the number of device level exceptions that have occurred since the last time this variable is reset. Writing a value of 0 will reset it. The device_lvl_exception_id reports the exception ID which is the qDeviceLevelExceptionID attribute of the device JEDEC specifications version 4.1 and later. The user space application can query these sysfs nodes to get more information about the device level exception. Signed-off-by: Bao D.
