[PATCH] selftests/sysctl: fix wording of help messages

by Bharadwaj Raju

Fix paramter -> parameter, and recomended -> recommended in sysctl.sh's help messages. Also correct grammar: "number amount of times is recommended" etc -> "the recommended number of times".

[PATCH net-next v6 0/7] Some pktgen fixes/improvments (part I)

by Peter Seiderer

While taking a look at '[PATCH net] pktgen: Avoid out-of-range in get_imix_entries' ([1]) and '[PATCH net v2] pktgen: Avoid out-of-bounds access in get_imix_entries' ([2], [3]) and doing some tests and code review I detected that the /proc/net/pktgen/... parsing logic does not honour the user given buffer bounds (resulting in out-of-bounds access). This can be observed e.g. by the following simple test (sometimes the old/'longer' previous value is re-read from the buffer): $ echo add_device lo@0 > /proc/net/pktgen/kpktgend_0 $ echo "min_pkt_size 12345" > /proc/net/pktgen/lo\@0 && grep min_pkt_size /proc/net/pktgen/lo\@0 Params: count 1000 min_pkt_size: 12345 max_pkt_size: 0 Result: OK: min_pkt_size=12345 $ echo -n "min_pkt_size 123" > /proc/net/pktgen/lo\@0 && grep min_pkt_size /proc/net/pktgen/lo\@0 Params: count 1000 min_pkt_size: 12345 max_pkt_size: 0 Result: OK: min_pkt_size=12345 $ echo "min_pkt_size 123" > /proc/net/pktgen/lo\@0 && grep min_pkt_size /proc/net/pktgen/lo\@0 Params: count 1000 min_pkt_size: 123 max_pkt_size: 0 Result: OK: min_pkt_size=123 So fix the out-of-bounds access (and some minor findings) and add a simple proc_net_pktgen selftest...

[PATCH net-next v2] tun: Pad virtio headers

by Akihiko Odaki

tun simply advances iov_iter when it needs to pad virtio header, which leaves the garbage in the buffer as is. This will become especially problematic when tun starts to allow enabling the hash reporting feature; even if the feature is enabled, the packet may lack a hash value and may contain a hole in the virtio header because the packet arrived before the feature gets enabled or does not contain the header fields to be hashed. If the hole is not filled with zero, it is impossible to tell if the packet lacks a hash value. In theory, a user of tun can fill the buffer with zero before calling read() to avoid such a problem, but leaving the garbage in the buffer is awkward anyway so replace advancing the iterator with writing zeros. A user might have initialized the buffer to some non-zero value, expecting tun to skip writing it. As this was never a documented feature, this seems unlikely. The overhead of filling the hole in the header is negligible when the header size is specified according to the specification as doing so will not make another cache line dirty under a reasonable assumption. Below is a proof of this statement: The first 10 bytes of the header is always written and tun also writes the packet itself immediately after the packet unless the packet is empty. This makes a hole between these writes whose size is: sz - 10 where sz is the specified header size. Therefore, we will never make another cache line dirty when: sz < L1_CACHE_BYTES + 10 where L1_CACHE_BYTES is the cache line size. Assuming L1_CACHE_BYTES >= 16, this inequation holds when: sz < 26. sz <= 20 according to the current specification so we even have a margin of 5 bytes in case that the header size grows in a future version of the specification.

[PATCH] selftests/tracing: Test only toplevel README file not the instances

by Steven Rostedt

From: Steven Rostedt <rostedt(a)goodmis.org> For the tests that have both a README attribute as well as the instance flag to run the tests as an instance, the instance version will always exit with UNSUPPORTED. That's because the instance directory does not contain a README file. Currently, the tests check for a README file in the directory that the test runs in and if there's a requirement for something to be present in the README file, it will not find it, as the instance directory doesn't have it. Have the tests check if the current directory is an instance directory, and if it is, check two directories above the current directory for the README file: /sys/kernel/tracing/README /sys/kernel/tracing/instances/foo/../../README Signed-off-by: Steven Rostedt (Google) <rostedt(a)goodmis.org> --- tools/testing/selftests/ftrace/test.d/functions | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/tools/testing/selftests/ftrace/test.d/functions b/tools/testing/selftests/ftrace/test.d/functions index 779f3e62ec90..9f2a67fbaf4d 100644 --- a/tools/testing/selftests/ftrace/test.d/functions +++ b/tools/testing/selftests/ftrace/test.d/functions @@ -156,7 +156,13 @@ check_requires() { # Check required files and tracers exit_unsupported fi elif [ "$r" != "$i" ]; then - if ! grep -Fq "$r" README ; then + # If this is an instance, check the top directory + if echo $TRACING_DIR | grep -q "/instances/"; then + test="$TRACING_DIR/../.." + else + test=$TRACING_DIR + fi + if ! grep -Fq "$r" $test/README ; then echo "Required feature pattern \"$r\" is not in README." exit_unsupported fi -- 2.45.2

[PATCH v6 0/9] Basic SEV-SNP Selftests

by Pratik R. Sampat

This patch series extends the sev_init2 and the sev_smoke test to exercise the SEV-SNP VM launch workflow. Primarily, it introduces the architectural defines, its support in the SEV library and extends the tests to interact with the SEV-SNP ioctl() wrappers. Patch 1 - Do not advertize SNP on incompatible firmware Patch 2 - Remove SEV support on platform init failure Patch 3 - SNP test for KVM_SEV_INIT2 Patch 4 - Add VMGEXIT helper Patch 5 - Introduce SEV+ VM type check Patch 6 - SNP iotcl() plumbing for the SEV library Patch 7 - Force set GUEST_MEMFD for SNP Patch 8 - Cleanups of smoke test - Decouple policy from type Patch 9 - SNP smoke test The series is based on git.kernel.org/pub/scm/virt/kvm/kvm.git next v5..v6 * Rename is_sev_platform_init to sev_fw_initialized (Nikunj) * Rename KVM CPU feature X86_FEATURE_SNP to X86_FEATURE_SEV_SNP (Nikunj) * Collected Tags from Nikunj, Pankaj, Srikanth. v4..v5: https://lore.kernel.org/kvm/8e7d8172-879e-4a28-8438-343b1c386ec9@amd.com/ * Introduced a check to disable advertising support for SEV, SEV-ES and SNP when platform initialization fails (Nikunj) * Remove the redundant SNP check within is_sev_vm() (Nikunj) * Cleanup of the encrypt_region flow for better readability (Nikunj) * Refactor paths to use the canonical $(ARCH) to rebase for kvm/next v3..v4: https://lore.kernel.org/kvm/20241114234104.128532-1-pratikrajesh.sampat@amd… * Remove SNP FW API version check in the test and ensure the KVM capability advertizes the presence of the feature. Retain the minimum version definitions to exercise these API versions in the smoke test * Retained only the SNP smoke test and SNP_INIT2 test * The SNP architectural defined merged with SNP_INIT2 test patch * SNP shutdown merged with SNP smoke test patch * Add SEV VM type check to abstract comparisons and reduce clutter * Define a SNP default policy which sets bits based on the presence of SMT * Decouple privatization and encryption for it to be SNP agnostic * Assert for only positive tests using vm_ioctl() * Dropped tested-by tags In summary - based on comments from Sean, I have primarily reduced the scope of this patch series to focus on breaking down the SNP smoke test patch (v3 - patch2) to first introduce SEV-SNP support and use this interface to extend the sev_init2 and the sev_smoke test. The rest of the v3 patchset that introduces ioctl, pre fault, fallocate and negative tests, will be re-worked and re-introduced subsequently in future patch series post addressing the issues discussed. v2..v3: https://lore.kernel.org/kvm/20240905124107.6954-1-pratikrajesh.sampat@amd.c… * Remove the assignments for the prefault and fallocate test type enums. * Fix error message for sev launch measure and finish. * Collect tested-by tags [Peter, Srikanth] Pratik R.

[PATCH] kunit: qemu_configs: SH: Respect kunit cmdline

by Thomas Weißschuh

The default SH kunit configuration sets CONFIG_CMDLINE_OVERWRITE which completely disregards the cmdline passed from the bootloader/QEMU in favor of the builtin CONFIG_CMDLINE. However the kunit tool needs to pass arguments to the in-kernel kunit core, for filters and other runtime parameters. Enable CONFIG_CMDLINE_EXTEND instead, so kunit arguments are respected.
