[PATCH 00/14] nSVM fixes and optional features

by Maxim Levitsky

Those are few patches I was working on lately, all somewhat related to the two CVEs that I found recently. First 7 patches fix various minor bugs that relate to these CVEs. The rest of the patches implement various optional SVM features, some of which the guest could enable anyway due to incorrect checking of virt_ext field. Last patch is somewhat an RFC, I would like to hear your opinion on that. I also implemented nested TSC scaling while at it. As for other optional SVM features here is my summary of few features I took a look at: X86_FEATURE_DECODEASSISTS: this feature should make it easier for the L1 to emulate an instruction on MMIO access, by not needing to read the guest memory but rather using the instruction bytes that the CPU already fetched. The challenge of implementing this is that we sometimes inject #PF and #NPT syntenically and in those cases we must be sure we set the correct instruction bytes. Also this feature adds assists for MOV CR/DR, INTn, and INVLPG, which aren't that interesting but must be supported as well to expose this feature to the nested guest. X86_FEATURE_VGIF Might allow the L2 to run the L3 a bit faster, but due to crazy complex logic we already have around int_ctl and vgif probably not worth it. X86_FEATURE_VMCBCLEAN Should just be enabled, because otherwise L1 doesn't even attempt to set the clean bits. But we need to know if we can take an advantage of these bits first. X86_FEATURE_FLUSHBYASID X86_FEATURE_AVIC These two features would be very good to enable, but that would require lots of work, and will be done eventually. There are few more nested SVM features that I didn't yet had a chance to take a look at.

[PATCH v4 0/3] kunit: allow running test suites/cases individually

by Daniel Latypov

Allow running each suite or each test case alone per kernel boot. The motivation for this is to debug "test hermeticity" issues. This new --run_isolated flag would be a good first step to try and narrow down root causes. Context: sometimes tests pass/fail depending on what ran before them. Memory corruption errors in particular might only cause noticeable issues later on. But you can also have the opposite, where "fixing" one test causes another to start failing. Usage: $ ./tools/testing/kunit/kunit.py run --kunitconfig=lib/kunit --run_isolated=suite $ ./tools/testing/kunit/kunit.py run --kunitconfig=lib/kunit --run_isolated=test $ ./tools/testing/kunit/kunit.py run --kunitconfig=lib/kunit --run_isolated=test example The last one would provide output like ======== [PASSED] example ======== [PASSED] example_simple_test ============================================================ Testing complete. 1 tests run. 0 failed. 0 crashed. 0 skipped.

[PATCH] kunit: tool: show list of valid --arch options when invalid

by Daniel Latypov

Consider this attempt to run KUnit in QEMU: $ ./tools/testing/kunit/kunit.py run --arch=x86 Before you'd get this error message: kunit_kernel.ConfigError: x86 is not a valid arch After: kunit_kernel.ConfigError: x86 is not a valid arch, options are ['alpha', 'arm', 'arm64', 'i386', 'powerpc', 'riscv', 's390', 'sparc', 'x86_64'] This should make it a bit easier for people to notice when they make typos, etc. Currently, one would have to dive into the python code to figure out what the valid set is.

[PATCH] kunit: tool: misc fixes (unused vars, imports, leaked files)

by Daniel Latypov

Drop some variables in unit tests that were unused and/or add assertions based on them. For ExitStack, it was imported, but the `es` variable wasn't used so it didn't do anything, and we were leaking the file objects. Refactor it to just use nested `with` statements to properly close them. And drop the direct use of .close() on file objects in the kunit tool unit test, as these can be leaked if test assertions fail.

[PATCH v2] kunit: fix reference count leak in kfree_at_end

by Xiyu Yang

The reference counting issue happens in the normal path of kfree_at_end(). When kunit_alloc_and_get_resource() is invoked, the function forgets to handle the returned resource object, whose refcount increased inside, causing a refcount leak. Fix this issue by calling kunit_alloc_resource() instead of kunit_alloc_and_get_resource().
