virtio-blk: remove VIRTIO_BLK_F_SCSI support

2020-02-06T08:40:26+00:00

Since the need for a special flag to support SCSI passthrough on a block device was added in May 2017 the SCSI passthrough support in virtio-blk has been disabled. It has always been a bad idea (just ask the original author..) and we have virtio-scsi for proper passthrough. The feature also never made it into the virtio 1.0 or later specifications.

powerpc: configs: Cleanup old Kconfig options

2020-01-31T10:29:03+00:00

CONFIG_ENABLE_WARN_DEPRECATED is gone since commit 771c035372a0 ("deprecate the '__deprecated' attribute warnings entirely and for good"). CONFIG_IOSCHED_DEADLINE and CONFIG_IOSCHED_CFQ are gone since commit f382fb0bcef4 ("block: remove legacy IO schedulers"). The IOSCHED_DEADLINE was replaced by MQ_IOSCHED_DEADLINE and it will be now enabled by default (along with MQ_IOSCHED_KYBER).

powerpc/configs/skiroot: Enable some more hardening options

2020-01-31T10:20:35+00:00

Enable more hardening options. Note BUG_ON_DATA_CORRUPTION selects DEBUG_LIST and is essentially just a synonym for it. DEBUG_SG, DEBUG_NOTIFIERS, DEBUG_LIST, DEBUG_CREDENTIALS and SCHED_STACK_END_CHECK should all be low overhead and just add a few extra checks. SLAB_FREELIST_RANDOM, and SLUB_DEBUG_ON will add some overhead to the SLAB allocator, but nothing that should be meaningful for skiroot. Unselecting SLAB_MERGE_DEFAULT causes the SLAB to use more memory, but the skiroot kernel shouldn't be memory constrained on any of our systems, all it does is run a small bootloader. Disabling merging has some security/robustness benefit as it means a user-after-free or overflow will be limited to the objects in that slab, rather than potentially affecting objects from unrelated slabs that have been merged. Note also that slab merging is disabled anyway by enabling SLUB_DEBUG_ON, because of the SLAB_NEVER_MERGE mask.

powerpc/configs/skiroot: Disable xmon default & enable reboot on panic

2020-01-31T10:20:31+00:00

If the skiroot kernel crashes we don't want it sitting at an xmon prompt forever. Instead it's more helpful to reboot and bring the boot loader back up, and if the crash was transient we can then boot successfully. Similarly if we panic we should reboot, with a short timeout in case someone is watching the console.

powerpc/configs/skiroot: Enable security features

2020-01-31T10:20:17+00:00

This turns on HARDENED_USERCOPY with HARDENED_USERCOPY_PAGESPAN, and FORTIFY_SOURCE. It also enables SECURITY_LOCKDOWN_LSM with _EARLY and LOCK_DOWN_KERNEL_FORCE_INTEGRITY options enabled. This still allows xmon to be used in read-only mode. MODULE_SIG is selected by lockdown, so it is still enabled. Because we're setting LOCK_DOWN_KERNELFORCE_INTEGRITY=y we also need to enable KEXEC_FILE=y so that kexec continues to work.

powerpc/configs/skiroot: Drop HID_LOGITECH

2020-01-31T10:19:52+00:00

Commit bdd08fff4915 ("HID: logitech: Add depends on LEDS_CLASS to Logitech Kconfig entry") made HID_LOGITECH depend on LEDS_CLASS which we do not enable, meaning we are not actually enabling those drivers any more. The Kconfig help text suggests USB HID compliant Logictech devices will continue to work without HID_LOGITECH, so just drop it.
