[PATCH v2] selftests/sgx: Ignore OpenSSL 3.0 deprecated functions warning

by Kristen Carlson Accardi

OpenSSL 3.0 deprecates some of the functions used in the SGX selftests, causing build errors on new distros. For now ignore the warnings until support for the functions is no longer available and mark FIXME so that it can be clear this should be removed at some point.

[PATCH v4 0/4] Introduce security_create_user_ns()

by Frederick Lawler

While creating a LSM BPF MAC policy to block user namespace creation, we used the LSM cred_prepare hook because that is the closest hook to prevent a call to create_user_ns(). The calls look something like this: cred = prepare_creds() security_prepare_creds() call_int_hook(cred_prepare, ... if (cred) create_user_ns(cred) We noticed that error codes were not propagated from this hook and introduced a patch [1] to propagate those errors. The discussion notes that security_prepare_creds() is not appropriate for MAC policies, and instead the hook is meant for LSM authors to prepare credentials for mutation. [2] Ultimately, we concluded that a better course of action is to introduce a new security hook for LSM authors. [3] This patch set first introduces a new security_create_user_ns() function and userns_create LSM hook, then marks the hook as sleepable in BPF.

[PATCH v1 00/10] kselftest/arm64: EXTRA_CONTEXT related fixes

by Mark Brown

The arm64 architecture originally made the signal context a fixed size structure containing a linked list of records with the various kinds of register and other state which may be present. When SVE was implemented it was realised that it supported implementations with more state than could fit in that structure so a new record type EXTRA_CONTEXT was introduced allowing the signal context to be extended beyond the original size. Unfortunately the signal handling tests can not cope with these EXTRA_CONTEXT records at all - some support was implemented but it simply never worked. This series contains one fix for the actual kernel, rasing an arbatrary limit which can be exceeded by SME systems, and an overhaul of the handling of EXTRA_CONTEXT in the signal tests which fixes issues which would cause spurious failures when one was encountered and then extends the tests to handle the contents of an EXTRA_CONTEXT record. This allows removal of the limits on validation of signal contexts for larger SVE and SME vector lengths from the existing test code. The separately sent kernel fix "arm64/signal: Raise limit on stack frames" is needed for these tests to pass, tests for larger SME vector lengths trigger the issue it fixes. The fixes for baseline issues were previously sent separately.

[PATCH v2 0/3] arm64/sve: Document our actual SVE syscall ABI

by Mark Brown

Currently our SVE syscall ABI documentation does not reflect the actual implemented ABI, it says that register state not shared with FPSIMD becomes undefined on syscall when in reality we always clear it. Since changing this would cause a change in the observed kernel behaviour there is a substantial desire to avoid taking advantage of the documented ABI so instead let's document what we actually do so it's clear that it is in reality an ABI. There has been some pushback on tightening the documentation in the past but it is hard to see who that helps, it makes the implementation decisions less clear and makes it harder for people to discover and make use of the actual ABI. The main practical concern is that qemu's user mode does not currently flush the registers. v2: - Rebase onto v6.0-rc1.

[PATCH v1] kselftest/arm64: Add simple hwcap validation

by Mark Brown

Add some trivial hwcap validation which checks that /proc/cpuinfo and AT_HWCAP agree with each other and can verify that for extensions that can generate a SIGILL due to adding new instructions one appears or doesn't appear as expected. I've added SVE and SME, other capabilities can be added later if this gets merged. This isn't super exciting but on the other hand took very little time to write and should be handy when verifying that you wired up AT_HWCAP properly.

[PATCH v1 0/4] kselftest/arm64: Floating point stress test harness

by Mark Brown

This series has a few small enhancements for the existing standalone floating point stress tests and then builds on those with a kselftest integrated program which gives those a very quick spin from within kselftest, as well as having an option to set a custom timeout to allow for use with longer soak testing. This makes it much easier to get thorough testing of the floating point state management logic, rather than requiring custom setup for coverage of the various vector lengths in the system as is needed at present. It might be nice in future to extend this to attach to some or all of the test programs with ptrace and read/write their registers as another means of potentially triggering race conditions or corruption but that's definitely another step. This series has a runtime dependency on a fix "arm64/signal: Raise limit on stack frames" which has previously been posted separately, without this fix spurious failures will be seen on systems supporting large SME vector lengths.
