Anyway, this is found through code inspection, and I am not sure whether it would actually cause serious issues.

The patch titled Subject: mm: zswap: fix race between [de]compression and CPU hotunplug has been added to the -mm mm-hotfixes-unstable branch. Its filename is mm-zswap-fix-race-between-compression-and-cpu-hotunplug.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patche… This patch will later appear in the mm-hotfixes-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Yosry Ahmed <yosryahmed(a)google.com> Subject: mm: zswap: fix race between [de]compression and CPU hotunplug Date: Thu, 19 Dec 2024 21:24:37 +0000 In zswap_compress() and zswap_decompress(), the per-CPU acomp_ctx of the current CPU at the beginning of the operation is retrieved and used throughout. However, since neither preemption nor migration are disabled, it is possible that the operation continues on a different CPU. If the original CPU is hotunplugged while the acomp_ctx is still in use, we run into a UAF bug as the resources attached to the acomp_ctx are freed during hotunplug in zswap_cpu_comp_dead(). The problem was introduced in commit 1ec3b5fe6eec ("mm/zswap: move to use crypto_acomp API for hardware acceleration") when the switch to the crypto_acomp API was made. Prior to that, the per-CPU crypto_comp was retrieved using get_cpu_ptr() which disables preemption and makes sure the CPU cannot go away from under us. Preemption cannot be disabled with the crypto_acomp API as a sleepable context is needed. Commit 8ba2f844f050 ("mm/zswap: change per-cpu mutex and buffer to per-acomp_ctx") increased the UAF surface area by making the per-CPU buffers dynamic, adding yet another resource that can be freed from under zswap compression/decompression by CPU hotunplug. There are a few ways to fix this: (a) Add a refcount for acomp_ctx. (b) Disable migration while using the per-CPU acomp_ctx. (c) Disable CPU hotunplug while using the per-CPU acomp_ctx by holding the CPUs read lock. Implement (c) since it's simpler than (a), and (b) involves using migrate_disable() which is apparently undesired (see huge comment in include/linux/preempt.h).

[PATCH v3 3/3] arm64: errata: Add newer ARM cores to the spectre_bhb_loop_affected() lists

by Douglas Anderson

When comparing to the ARM list [1], it appears that several ARM cores were missing from the lists in spectre_bhb_loop_affected(). Add them. NOTE: for some of these cores it may not matter since other ways of clearing the BHB may be used (like the CLRBHB instruction or ECBHB), but it still seems good to have all the info from ARM's whitepaper included.

[PATCH v2 1/6] arm64: errata: Assume that unknown CPUs _are_ vulnerable to Spectre BHB

by Douglas Anderson

The code for detecting CPUs that are vulnerable to Spectre BHB was based on a hardcoded list of CPU IDs that were known to be affected. Unfortunately, the list mostly only contained the IDs of standard ARM cores. The IDs for many cores that are minor variants of the standard ARM cores (like many Qualcomm Kyro CPUs) weren't listed. This led the code to assume that those variants were not affected. Flip the code on its head and instead list CPU IDs for cores that are known to be _not_ affected. Now CPUs will be assumed vulnerable until added to the list saying that they're safe. As of right now, the only CPU IDs added to the "unaffected" list are ARM Cortex A35, A53, and A55. This list was created by looking at older cores listed in cputype.h that weren't listed in the "affected" list previously. Unfortunately, while this solution is better than what we had before, it's still an imperfect solution. Specifically there are two ways to mitigate Spectre BHB and one of those ways is parameterized with a "k" value indicating how many loops are needed to mitigate. If we have an unknown CPU ID then we've got to guess about how to mitigate it. Since more cores seem to be mitigated by looping (and because it's unlikely that the needed FW code will be in place for FW mitigation for unknown cores), we'll choose looping for unknown CPUs and choose the highest "k" value of 32. The downside of our guessing is that some CPUs may now report as "mitigated" when in reality they should need a firmware mitigation. We'll choose to put a WARN_ON splat in the logs in this case any time we had to make a guess since guessing the right mitigation is pretty awful. Hopefully this will encourage CPU vendors to add their CPU IDs to the list.
