[GIT PULL] Kselftest next update for Linux 6.9-rc1

by Shuah Khan

Hi Linus, Please pull the following Kselftest update for Linux 6.9-rc1. This kselftest next update for Linux 6.9-rc1 consists of: -- livepatch restructuring to move the module out of lib to be built as a out-of-tree modules during kselftest build. This change makes it easier change, debug and rebuild the tests by running make on the selftests/livepatch directory, which is not currently possible since the modules on lib/livepatch are build and installed using the main makefile modules target. -- livepatch restructuring fixes for problems found by kernel test robot. The change skips the test if kernel-devel isn't installed (default value of KDIR), or if KDIR variable passed doesn't exists. -- resctrl test restructuring and new non-contiguous CBMs CAT test -- new ktap_helpers to print diagnostic messages, pass/fail tests based on exit code, abort test, and finish the test. -- a new test verify power supply properties. -- a new ftrace to exercise function tracer across cpu hotplug. -- timeout increase for mqueue test to allow the test to run on i3.metal AWS instances. -- minor spelling corrections in several tests. -- missing gitignore files and changes to existing gitignore files. diff is attached. thanks, -- Shuah ---------------------------------------------------------------- The following changes since commit 6613476e225e090cc9aad49be7fa504e290dd33d: Linux 6.8-rc1 (2024-01-21 14:11:32 -0800) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest tags/linux_kselftest-next-6.9-rc1 for you to fetch changes up to 5d94da7ff00ef45737a64d947e7ff45aca972782: kselftest: Add basic test for probing the rust sample modules (2024-03-04 13:13:04 -0700) ---------------------------------------------------------------- linux_kselftest-next-6.9-rc1 This kselftest next update for Linux 6.9-rc1 consists of: -- livepatch restructuring to move the module out of lib to be built as a out-of-tree modules during kselftest build.

[GIT PULL] KUnit next update for Linux 6.9-rc1

by Shuah Khan

Hi Linus, Please pull the following KUnit next update for Linux 6.8-rc1. This KUnit next update for Linux 6.9-rc1 consists of: -- fix to make kunit_bus_type const -- kunit tool change to Print UML command -- DRM device creation helpers are now using the new kunit device creation helpers. This change resulted in DRM helpers switching from using a platform_device, to a dedicated bus and device type used by kunit. kunit devices don't set DMA mask and this caused regression on some drm tests as they can't allocate DMA buffers. Fix this problem by setting DMA masks on the kunit device during initialization. -- KUnit has several macros which accept a log message, which can contain printf format specifiers. Some of these (the explicit log macros) already use the __printf() gcc attribute to ensure the format specifiers are valid, but those which could fail the test, and hence used __kunit_do_failed_assertion() behind the scenes, did not. These include: KUNIT_EXPECT_*_MSG(), KUNIT_ASSERT_*_MSG(), and KUNIT_FAIL() A 9 patch series adds the __printf() attribute, and fixes all of the issues uncovered. Note: make allmodconfig x86 passed passed for me on March 4th linux-next (This could be with Stephen's fix up for the following problem). Stephen found a problem in drivers/gpu/drm/tests/drm_buddy_test.c Caused by commit 806cb2270237 ("kunit: Annotate _MSG assertion variants with gnu printf specifiers") interacting with commit c70703320e55 ("drm/tests/drm_buddy: add alloc_range_bias test") from the drm-misc-fixes tree. Stephen found that the problem is not with the format string types, but with a missing argument i.e. there is another argument required by the format string. It is easier to fix this problem in the drm-misc-fixes tree. The hope is that the fix to the problem has been sent to you or will be sent to you before the merge. If not Stephen's fix up will be necessary. diff is attached. thanks, -- Shuah ---------------------------------------------------------------- The following changes since commit d206a76d7d2726f3b096037f2079ce0bd3ba329b: Linux 6.8-rc6 (2024-02-25 15:46:06 -0800) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest tags/linux_kselftest-kunit-6.9-rc1 for you to fetch changes up to 806cb2270237ce2ec672a407d66cee17a07d3aa2: kunit: Annotate _MSG assertion variants with gnu printf specifiers (2024-02-28 13:07:49 -0700) ---------------------------------------------------------------- linux_kselftest-kunit-6.9-rc1 This KUnit next update for Linux 6.9-rc1 consists of: -- fix to make kunit_bus_type const -- kunit tool change to Print UML command -- DRM device creation helpers are now using the new kunit device creation helpers.

[PATCH AUTOSEL 6.6 09/17] selftests: mptcp: explicitly trigger the listener diag code-path

by Sasha Levin

From: Paolo Abeni <pabeni(a)redhat.com> [ Upstream commit b4b51d36bbaa3ddb93b3e1ca3a1ef0aa629d6521 ] The mptcp diag interface already experienced a few locking bugs that lockdep and appropriate coverage have detected in advance. Let's add a test-case triggering the relevant code path, to prevent similar issues in the future. Be careful to cope with very slow environments. Note that we don't need an explicit timeout on the mptcp_connect subprocess to cope with eventual bug/hang-up as the final cleanup terminating the child processes will take care of that.

[PATCH net-next v3 0/4] net: gro: encapsulation bug fix and flush checks improvements

by Richard Gobert

This series fixes a bug in the complete phase of UDP in GRO, in which socket lookup fails due to using network_header when parsing encapsulated packets. The fix is to pass p_off parameter in *_gro_complete. Next, the fields network_offset and inner_network_offset are added to napi_gro_cb, and are both set during the receive phase of GRO. This is then leveraged in the next commit to remove flush_id state from napi_gro_cb, and stateful code in {ipv6,inet}_gro_receive which may be unnecessarily complicated due to encapsulation support in GRO. In addition, udpgro_fwd selftest is adjusted to include the socket lookup case for vxlan. This selftest will test its supposed functionality once local bind support is merged (https://lore.kernel.org/netdev/df300a49-7811-4126-a56a-a77100c8841b@gmail.c…). v2 -> v3: - Use napi_gro_cb instead of skb->{offset} - v2: https://lore.kernel.org/netdev/2ce1600b-e733-448b-91ac-9d0ae2b866a4@gmail.c… v1 -> v2: - Pass p_off in *_gro_complete to fix UDP bug - Remove more conditionals and memory fetches from inet_gro_flush - v1: https://lore.kernel.org/netdev/e1d22505-c5f8-4c02-a997-64248480338b@gmail.c… Richard Gobert (4): net: gro: add p_off param in *_gro_complete selftests/net: add local address bind in vxlan selftest net: gro: add {inner_}network_offset to napi_gro_cb net: gro: move L3 flush checks to tcp_gro_receive drivers/net/geneve.c | 7 +- drivers/net/vxlan/vxlan_core.c | 11 ++-- include/linux/etherdevice.h | 2 +- include/linux/netdevice.h | 3 +- include/linux/udp.h | 2 +- include/net/gro.h | 36 +++++++---- include/net/inet_common.h | 2 +- include/net/tcp.h | 6 +- include/net/udp.h | 8 +-- include/net/udp_tunnel.h | 2 +- net/8021q/vlan_core.c | 6 +- net/core/gro.c | 6 +- net/ethernet/eth.c | 5 +- net/ipv4/af_inet.c | 49 ++------------ net/ipv4/fou_core.c | 9 +-- net/ipv4/gre_offload.c | 6 +- net/ipv4/tcp_offload.c | 79 ++++++++++++++++++----- net/ipv4/udp.c | 3 +- net/ipv4/udp_offload.c | 26 ++++---- net/ipv6/ip6_offload.c | 41 +++++------- net/ipv6/tcpv6_offload.c | 7 +- net/ipv6/udp.c | 3 +- net/ipv6/udp_offload.c | 13 ++-- tools/testing/selftests/net/udpgro_fwd.sh | 10 ++- 24 files changed, 187 insertions(+), 155 deletions(-) -- 2.36.1

[RFC PATCH 0/5] Add support for suppressing warning backtraces

by Guenter Roeck

Some unit tests intentionally trigger warning backtraces by passing bad parameters to kernel API functions. Such unit tests typically check the return value from such calls, not the existence of the warning backtrace. Such intentionally generated warning backtraces are neither desirable nor useful for a number of reasons. - They can result in overlooked real problems. - A warning that suddenly starts to show up in unit tests needs to be investigated and has to be marked to be ignored, for example by adjusting filter scripts. Such filters are ad-hoc because there is no real standard format for warnings. On top of that, such filter scripts would require constant maintenance. One option to address problem would be to add messages such as "expected warning backtraces start / end here" to the kernel log. However, that would again require filter scripts, it might result in missing real problematic warning backtraces triggered while the test is running, and the irrelevant backtrace(s) would still clog the kernel log. Solve the problem by providing a means to identify and suppress specific warning backtraces while executing test code. Support suppressing multiple backtraces while at the same time limiting changes to generic code to the absolute minimum. Architecture specific changes are kept at minimum by retaining function names only if both CONFIG_DEBUG_BUGVERBOSE and CONFIG_KUNIT are enabled. The first patch of the series introduces the necessary infrastructure. The second patch marks the warning message in drm_calc_scale() in the DRM subsystem as intentional where warranted. This patch is intended to serve as an example for the use of the functionality introduced with this series. The last three patches in the series introduce the necessary architecture specific changes for x86, arm64, and loongarch. This series is based on the RFC patch and subsequent discussion at https://patchwork.kernel.org/project/linux-kselftest/patch/02546e59-1afe-4b… and offers a more comprehensive solution of the problem discussed there. Checkpatch note: Remaining checkpatch errors and warnings were deliberately ignored. Some are triggered by matching coding style or by comments interpreted as code, others by assembler macros which are disliked by checkpatch. Suggestions for improvements are welcome. Some questions: - Is the general approach promising ? If not, are there other possible solutions ? - Function pointers are only added to the __bug_table section if both CONFIG_KUNIT and CONFIG_DEBUG_BUGVERBOSE are enabled. This avoids image size increases if CONFIG_KUNIT=n. Downside is slightly more complex architecture specific assembler code. If function pointers were always added to the __bug_table section, vmlinux image size would increase by approximately 0.6-0.7%. Is the increased complexity in assembler code worth the reduced image size ? I think so, but I would like to hear other opinions. - There are additional possibilities associated with storing the bug function name in the __bug_table section. It could be independent of KUNIT, it could be a configuration flag, and/or it could be used to display the name of the offending function in BUG/WARN messages. Is any of those of interest ? ---------------------------------------------------------------- Guenter Roeck (5): bug: Core support for suppressing warning backtraces drm: Suppress intentional warning backtraces in scaling unit tests x86: Add support for suppressing warning tracebacks arm64: Add support for suppressing warning tracebacks loongarch: Add support for suppressing warning tracebacks arch/arm64/include/asm/asm-bug.h | 29 +++++++++++++------- arch/arm64/include/asm/bug.h | 8 +++++- arch/loongarch/include/asm/bug.h | 38 ++++++++++++++++++-------- arch/x86/include/asm/bug.h | 21 +++++++++++---- drivers/gpu/drm/tests/drm_rect_test.c | 6 +++++ include/asm-generic/bug.h | 16 ++++++++--- include/kunit/bug.h | 51 +++++++++++++++++++++++++++++++++++ include/linux/bug.h | 13 +++++++++ lib/bug.c | 51 ++++++++++++++++++++++++++++++++--- lib/kunit/Makefile | 6 +++-- lib/kunit/bug.c | 40 +++++++++++++++++++++++++++ 11 files changed, 243 insertions(+), 36 deletions(-) create mode 100644 include/kunit/bug.h create mode 100644 lib/kunit/bug.c

[PATCH v4 0/7] of: populate of_root node if bootloader doesn't

by Stephen Boyd

Arch maintainers, please ack/review patches. This is a resend of a series from Frank last year[1]. I worked in Rob's review comments to unconditionally call unflatten_device_tree() and fixup/audit calls to of_have_populated_dt() so that behavior doesn't change. I need this series so I can add DT based tests in the clk framework. Either I can merge it through the clk tree once everyone is happy, or Rob can merge it through the DT tree and provide some branch so I can base clk patches on it. Changes from v3 (https://lore.kernel.org/r/20240202195909.3458162-1-sboyd@kernel.org): * Made OF_UNITTEST depend on OF_EARLY_FLATREE * Made OF_EARLY_FLATREE depend on absence of arches that don't call unflatten_device_tree() * Added of_ prefix to dtb_ prefixed KUnit tests * Picked up tags Changes from v2 (https://lore.kernel.org/r/20240130004508.1700335-1-sboyd@kernel.org): * Reorder patches to have OF changes largely first * No longer modify initial_boot_params if ACPI=y * Put arm64 patch back to v1 Changes from v1 (https://lore.kernel.org/r/20240112200750.4062441-1-sboyd@kernel.org): * x86 patch included * arm64 knocks out initial dtb if acpi is in use * keep Kconfig hidden but def_bool enabled otherwise Changes from Frank's series[1]: * Add a DTB loaded kunit test * Make of_have_populated_dt() return false if the DTB isn't from the bootloader * Architecture calls made unconditional so that a root node is always made Frank Rowand (2): of: Create of_root if no dtb provided by firmware of: unittest: treat missing of_root as error instead of fixing up Stephen Boyd (5): of: Always unflatten in unflatten_and_copy_device_tree() um: Unconditionally call unflatten_device_tree() x86/of: Unconditionally call unflatten_and_copy_device_tree() arm64: Unconditionally call unflatten_device_tree() of: Add KUnit test to confirm DTB is loaded arch/arm64/kernel/setup.c | 3 +- arch/um/kernel/dtb.c | 14 ++++---- arch/x86/kernel/devicetree.c | 24 +++++++------- drivers/of/.kunitconfig | 3 ++ drivers/of/Kconfig | 14 ++++++-- drivers/of/Makefile | 4 ++- drivers/of/empty_root.dts | 6 ++++ drivers/of/fdt.c | 64 +++++++++++++++++++++++++++--------- drivers/of/of_test.c | 57 ++++++++++++++++++++++++++++++++ drivers/of/platform.c | 3 -- drivers/of/unittest.c | 16 +++------ include/linux/of.h | 25 ++++++++------ 12 files changed, 168 insertions(+), 65 deletions(-) create mode 100644 drivers/of/.kunitconfig create mode 100644 drivers/of/empty_root.dts create mode 100644 drivers/of/of_test.c [1] https://lore.kernel.org/r/20230317053415.2254616-1-frowand.list@gmail.com base-commit: 6613476e225e090cc9aad49be7fa504e290dd33d -- https://git.kernel.org/pub/scm/linux/kernel/git/clk/linux.git/ https://git.kernel.org/pub/scm/linux/kernel/git/sboyd/spmi.git

[PATCH 00/13] selftests/resctrl: resctrl_val() related cleanups & improvements

by Ilpo Järvinen

Hi all, This series does a number of cleanups into resctrl_val() and generalizes it by removing test name specific handling from the function. One of the changes improves MBA/MBM measurement by narrowing down the period the resctrl FS derived memory bandwidth numbers are measured over. My feel is it didn't cause noticeable difference into the numbers because they're generally good anyway except for the small number of outliers. To see the impact on outliers, I'd need to setup a test to run large number of replications and do a statistical analysis, which I've not spent my time on. Even without the statistical analysis, the new way to measure seems obviously better and makes sense even if I cannot see a major improvement with the setup I'm using. This series has some conflicts with SNC series from Maciej and also with the MBA/MBM series from Babu. -- i. Ilpo Järvinen (13): selftests/resctrl: Convert get_mem_bw_imc() fd close to for loop selftests/resctrl: Calculate resctrl FS derived mem bw over sleep(1) only selftests/resctrl: Consolidate get_domain_id() into resctrl_val() selftests/resctrl: Use correct type for pids selftests/resctrl: Cleanup bm_pid and ppid usage & limit scope selftests/resctrl: Rename measure_vals() to measure_mem_bw_vals() & document selftests/resctrl: Add ->measure() callback to resctrl_val_param selftests/resctrl: Add ->init() callback into resctrl_val_param selftests/resctrl: Simplify bandwidth report type handling selftests/resctrl: Make some strings passed to resctrlfs functions const selftests/resctrl: Convert ctrlgrp & mongrp to pointers selftests/resctrl: Remove mongrp from MBA test selftests/resctrl: Remove test name comparing from write_bm_pid_to_resctrl() tools/testing/selftests/resctrl/cache.c | 6 +- tools/testing/selftests/resctrl/cat_test.c | 5 +- tools/testing/selftests/resctrl/cmt_test.c | 21 +- tools/testing/selftests/resctrl/mba_test.c | 34 ++- tools/testing/selftests/resctrl/mbm_test.c | 33 ++- tools/testing/selftests/resctrl/resctrl.h | 48 ++-- tools/testing/selftests/resctrl/resctrl_val.c | 269 ++++++------------ tools/testing/selftests/resctrl/resctrlfs.c | 55 ++-- 8 files changed, 224 insertions(+), 247 deletions(-) -- 2.39.2
