[PATCH v2 1/2] random: split initialization into early step and later step

by Jason A. Donenfeld

The full RNG initialization relies on some timestamps, made possible with general functions like time_init() and timekeeping_init(). However, these are only available rather late in initialization. Meanwhile, other things, such as memory allocator functions, make use of the RNG much earlier. So split RNG initialization into two phases. We can give arch randomness very early on, and then later, after timekeeping and such are available, initialize the rest. This ensures that, for example, slabs are properly randomized if RDRAND is available. Without this, CONFIG_SLAB_FREELIST_RANDOM=y loses a degree of its security, because its random seed is potentially deterministic, since it hasn't yet incorporated RDRAND. It also makes it possible to use a better seed in kfence, which currently relies on only the cycle counter. Another positive consequence is that on systems with RDRAND, running with CONFIG_WARN_ALL_UNSEEDED_RANDOM=y results in no warnings at all.

patch "usb: typec: ucsi: Remove incorrect warning" added to usb-testing

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled usb: typec: ucsi: Remove incorrect warning to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-testing branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will be merged to the usb-next branch sometime soon, after it passes testing, and the merge window is open. If you have any questions about this process, please let me know. From dd3de5ad032db61f3edd9c94daf27e52f8dc25ca Mon Sep 17 00:00:00 2001 From: Heikki Krogerus <heikki.krogerus(a)linux.intel.com> Date: Thu, 22 Sep 2022 17:59:24 +0300 Subject: usb: typec: ucsi: Remove incorrect warning Sink only devices do not have any source capabilities, so the driver should not warn about that. Also DRP (Dual Role Power) capable devices, such as USB Type-C docking stations, do not return any source capabilities unless they are plugged to a power supply themselves.

[PATCH 5.4 1/1] KVM: SEV: add cache flush to solve SEV cache incoherency issues

by Ovidiu Panait

From: Mingwei Zhang <mizhang(a)google.com> commit 683412ccf61294d727ead4a73d97397396e69a6b upstream. Flush the CPU caches when memory is reclaimed from an SEV guest (where reclaim also includes it being unmapped from KVM's memslots). Due to lack of coherency for SEV encrypted memory, failure to flush results in silent data corruption if userspace is malicious/broken and doesn't ensure SEV guest memory is properly pinned and unpinned. Cache coherency is not enforced across the VM boundary in SEV (AMD APM vol.2 Section 15.34.7). Confidential cachelines, generated by confidential VM guests have to be explicitly flushed on the host side. If a memory page containing dirty confidential cachelines was released by VM and reallocated to another user, the cachelines may corrupt the new user at a later time. KVM takes a shortcut by assuming all confidential memory remain pinned until the end of VM lifetime. Therefore, KVM does not flush cache at mmu_notifier invalidation events. Because of this incorrect assumption and the lack of cache flushing, malicous userspace can crash the host kernel: creating a malicious VM and continuously allocates/releases unpinned confidential memory pages when the VM is running. Add cache flush operations to mmu_notifier operations to ensure that any physical memory leaving the guest VM get flushed. In particular, hook mmu_notifier_invalidate_range_start and mmu_notifier_release events and flush cache accordingly. The hook after releasing the mmu lock to avoid contention with other vCPUs.
