[PATCH net-next] selftests/vsock: add initial vmtest.sh for vsock

by Bobby Eshleman

This commit introduces a new vmtest.sh runner for vsock. It uses virtme-ng/qemu to run tests in a VM. The tests are designed to validate both G2H and H2G paths. The testing tools from tools from tools/testing/vsock/ are reused. Currently, only vsock_test is used. Only tested on x86.

[PATCH 0/3] Fix up building KUnit tests for Cirrus Logic modules

by Richard Fitzgerald

This series fixes the KConfig for cs_dsp and cs-amp-lib tests so that CONFIG_KUNIT_ALL_TESTS doesn't cause them to add modules to the build. Patch 1 adds the ASoC CS35L56 driver to KUnit all_tests.config so that cs_dsp and cs-amp-lib will be included in the test build. Patch 2 and 3 fixup the KConfig entries for cs_dsp and cs-amp-lib. Nico Pache (1): firmware: cs_dsp: tests: Depend on FW_CS_DSP rather then enabling it Richard Fitzgerald (2): kunit: configs: Add some Cirrus Logic modules to all_tests ASoC: cs-amp-lib-test: Don't select SND_SOC_CS_AMP_LIB drivers/firmware/cirrus/Kconfig | 5 +---- sound/soc/codecs/Kconfig | 5 ++--- tools/testing/kunit/configs/all_tests.config | 2 ++ 3 files changed, 5 insertions(+), 7 deletions(-) -- 2.39.5

selftests: cgroup: Failures – Timeouts & OOM Issues Analysis

by Naresh Kamboju

As part of LKFT’s re-validation of known issues, we have observed that the selftests: cgroup suite is consistently failing across almost all LKFT-supported devices due to: - Test timeouts (45 seconds limit reached) - OOM-killer invocation ## Key Questions for Discussion: - Would it be beneficial to increase the test timeout to ~180 seconds to allow sufficient execution time? - Should we enhance logging to explicitly print failure reasons when a test fails? - Are there any missing dependencies that could be causing these failures? Note: The required selftests/cgroup/config options were included in LKFT's build and test plans. ## Devices Affected: The following DUTs consistently experience these failures: - dragonboard-410c (arm64) - dragonboard-845c (arm64) - e850-96 (arm64) - juno-r2 (arm64) - qemu-arm64 (arm64) - qemu-armv7 - qemu-x86_64 - rk3399-rock-pi-4b (arm64) - x15 (arm) - x86_64 Regression Analysis: - New regression? No (these failures have been observed for months/years). - Reproducibility? Yes, the failures occur consistently. - Test suite affected? selftests: cgroup (timeouts and OOM-related failures).

[PATCH net-next v25 00/23] Introducing OpenVPN Data Channel Offload

by Antonio Quartulli

Notable changes since v24: * disable TCP disconnections of attached sockets (tcp_disconnect() returns -EBUSY) - similarly to kTLS. * used rcu_replace_pointer instead of rcu_dereference_protected+rcu_assign_pointer * dropped useless skb->ignore_df = 1 * dropped unneded EXPORT_SYMBOL_GPL(udpv6_prot) * dropped obsolete comment for ovpn_crypto_key_slots_swap() * dropped calls to kfree() in ovpn_aead_encrypt/decrypt() (release is performed in ovpn_encrypt/decrypt_post()) * dropped NULL check before calling kfree() in ovpn_encrypt/decrypt_done() * converted seq_num from atomic64_t to atomic_t (IV exhaustion is now detected in case of wrap around) * call consume_skb() on skb when dropping keepalive message (it is not a failure) * made REMOTE_PORT mandatory when REMOTE_IPV4/6 is specified in peer_new/set call * ensured ovpn_nl_key_swap_notify() is called only once, even when parsing a batch of received packets concurrently Please note that some patches were already reviewed/tested by a few people.

[PATCH] lib: PRIME_NUMBERS_KUNIT_TEST should not select PRIME_NUMBERS

by Geert Uytterhoeven

Enabling a (modular) test should not silently enable additional kernel functionality, as that may increase the attack vector of a product. Fix this by making PRIME_NUMBERS_KUNIT_TEST depend on PRIME_NUMBERS instead of selecting it. After this, one can safely enable CONFIG_KUNIT_ALL_TESTS=m to build modules for all appropriate tests for ones system, without pulling in extra unwanted functionality, while still allowing a tester to manually enable PRIME_NUMBERS and this test suite on a system where PRIME_NUMBERS is not enabled by default.

[PATCH AUTOSEL 5.10 08/11] selftests/mincore: Allow read-ahead pages to reach the end of the file

by Sasha Levin

From: Qiuxu Zhuo <qiuxu.zhuo(a)intel.com> [ Upstream commit 197c1eaa7ba633a482ed7588eea6fd4aa57e08d4 ] When running the mincore_selftest on a system with an XFS file system, it failed the "check_file_mmap" test case due to the read-ahead pages reaching the end of the file. The failure log is as below: RUN global.check_file_mmap ... mincore_selftest.c:264:check_file_mmap:Expected i (1024) < vec_size (1024) mincore_selftest.c:265:check_file_mmap:Read-ahead pages reached the end of the file check_file_mmap: Test failed FAIL global.check_file_mmap This is because the read-ahead window size of the XFS file system on this machine is 4 MB, which is larger than the size from the #PF address to the end of the file. As a result, all the pages for this file are populated. blockdev --getra /dev/nvme0n1p5 8192 blockdev --getbsz /dev/nvme0n1p5 512 This issue can be fixed by extending the current FILE_SIZE 4MB to a larger number, but it will still fail if the read-ahead window size of the file system is larger enough. Additionally, in the real world, read-ahead pages reaching the end of the file can happen and is an expected behavior. Therefore, allowing read-ahead pages to reach the end of the file is a better choice for the "check_file_mmap" test case.

[PATCH AUTOSEL 5.15 09/15] selftests/mincore: Allow read-ahead pages to reach the end of the file

by Sasha Levin

From: Qiuxu Zhuo <qiuxu.zhuo(a)intel.com> [ Upstream commit 197c1eaa7ba633a482ed7588eea6fd4aa57e08d4 ] When running the mincore_selftest on a system with an XFS file system, it failed the "check_file_mmap" test case due to the read-ahead pages reaching the end of the file. The failure log is as below: RUN global.check_file_mmap ... mincore_selftest.c:264:check_file_mmap:Expected i (1024) < vec_size (1024) mincore_selftest.c:265:check_file_mmap:Read-ahead pages reached the end of the file check_file_mmap: Test failed FAIL global.check_file_mmap This is because the read-ahead window size of the XFS file system on this machine is 4 MB, which is larger than the size from the #PF address to the end of the file. As a result, all the pages for this file are populated. blockdev --getra /dev/nvme0n1p5 8192 blockdev --getbsz /dev/nvme0n1p5 512 This issue can be fixed by extending the current FILE_SIZE 4MB to a larger number, but it will still fail if the read-ahead window size of the file system is larger enough. Additionally, in the real world, read-ahead pages reaching the end of the file can happen and is an expected behavior. Therefore, allowing read-ahead pages to reach the end of the file is a better choice for the "check_file_mmap" test case.
