[PATCH net-next 00/15] selftests: mptcp: various improvements

by Matthieu Baerts (NGI0)

In this series from Geliang, there are various improvements in MPTCP selftests: sharing code, doing actions the same way, colours, etc. Patch 1 prints all error messages to stdout: what was done in almost all other MPTCP selftests. This can be now easily changed later if needed. Patch 2 makes sure the test counter is continuous in mptcp_connect.sh. Patch 3 aligns the messages that are printed in mptcp_connect.sh. Patch 4 prints each test results in mptcp_sockopt.sh, similar to what we have in the TAP output. Patch 5 moves the different test counters to a single one in mptcp_lib.sh, to uniform how it is used. Patch 6 moves how titles are printed from mptcp_join.sh to the lib, to be reused in patch 7 by all other MPTCP selftests. Patch 8 uses the '+=' operator to append strings instead of repeating twice the variable name: that's shorter, easier to read. Patch 9 adds colours for the [ OK ], [SKIP], [FAIL] and INFO keywords in all MPTCP selftests. Patch 10 to 12 are some preparation patches for patch 13: patch 10 modifies how some 'test_fail' helpers, patch 11 moves a helper from userspace_pm.sh to the lib, and patch 12 changes where titles are printed in userspace_pm.sh. Patch 13 moves some duplicated helpers from mptcp_join.sh and userspace_pm.sh to mptcp_lib.sh. Patch 14 moves duplicated read-only variables from mptcp_join.sh and userspace_pm.sh to mptcp_lib.sh as well. Patch 15 uses explicit variables instead of hard-coded numbers for the exit status.

[PATCH v2 00/31] NT synchronization primitive driver

by Elizabeth Figura

This patch series introduces a new char misc driver, /dev/ntsync, which is used to implement Windows NT synchronization primitives. This was previously submitted as an RFC [1]. Since there were no major changes requested to the last RFC revision, I've stripped the RFC prefix. [1] https://lore.kernel.org/lkml/20240131021356.10322-1-zfigura@codeweavers.com/ == Background == The Wine project emulates the Windows API in user space. One particular part of that API, namely the NT synchronization primitives, have historically been implemented via RPC to a dedicated "kernel" process. However, more recent applications use these APIs more strenuously, and the overhead of RPC has become a bottleneck. The NT synchronization APIs are too complex to implement on top of existing primitives without sacrificing correctness. Certain operations, such as NtPulseEvent() or the "wait-for-all" mode of NtWaitForMultipleObjects(), require direct control over the underlying wait queue, and implementing a wait queue sufficiently robust for Wine in user space is not possible. This proposed driver, therefore, implements the problematic interfaces directly in the Linux kernel. This driver was presented at Linux Plumbers Conference 2023. For those further interested in the history of synchronization in Wine and past attempts to solve this problem in user space, a recording of the presentation can be viewed here: https://www.youtube.com/watch?v=NjU4nyWyhU8 == Performance == The gain in performance varies wildly depending on the application in question and the user's hardware. For some games NT synchronization is not a bottleneck and no change can be observed, but for others frame rate improvements of 50 to 150 percent are not atypical. The following table lists frame rate measurements from a variety of games on a variety of hardware, taken by users Dmitry Skvortsov, FuzzyQuils, OnMars, and myself: Game Upstream ntsync improvement =========================================================================== Anger Foot 69 99 43% Call of Juarez 99.8 224.1 125% Dirt 3 110.6 860.7 678% Forza Horizon 5 108 160 48% Lara Croft: Temple of Osiris 141 326 131% Metro 2033 164.4 199.2 21% Resident Evil 2 26 77 196% The Crew 26 51 96% Tiny Tina's Wonderlands 130 360 177% Total War Saga: Troy 109 146 34% =========================================================================== == Patches == The intended semantics of the patches are broadly intended to match those of the corresponding Windows functions. For those not already familiar with the Windows functions (or their undocumented behaviour), patch 31/31 provides a detailed specification, and individual patches also include a brief description of the API they are implementing. The patches making use of this driver in Wine can be retrieved or browsed here: https://repo.or.cz/wine/zf.git/shortlog/refs/heads/ntsync5 == Implementation == Some aspects of the implementation may deserve particular comment: * In the interest of performance, each object is governed only by a single spinlock. However, NTSYNC_IOC_WAIT_ALL requires that the state of multiple objects be changed as a single atomic operation. In order to achieve this, we first take a device-wide lock ("wait_all_lock") any time we are going to lock more than one object at a time. The maximum number of objects that can be used in a vectored wait, and therefore the maximum that can be locked simultaneously, is 64. This number is NT's own limit. The acquisition of multiple spinlocks will degrade performance. This is a conscious choice, however. Wait-for-all is known to be a very rare operation in practice, especially with counts that approach the maximum, and it is the intent of the ntsync driver to optimize wait-for-any at the expense of wait-for-all as much as possible. * NT mutexes are tied to their threads on an OS level, and the kernel includes builtin support for "robust" mutexes. In order to keep the ntsync driver self-contained and avoid touching more code than necessary, it does not hook into task exit nor use pids. Instead, the user space emulator is expected to manage thread IDs and pass them as an argument to any relevant functions; this is the "owner" field of ntsync_wait_args and ntsync_mutex_args. When the emulator detects that a thread dies, it should therefore call NTSYNC_IOC_MUTEX_KILL on any open mutexes. * ntsync is module-capable mostly because there was nothing preventing it, and because it aided development. It is not a hard requirement, though. == Previous versions == Changes from v1: * Fix a broken rebase that stole part of the Kconfig documentation from the neighbouring entry, per Randy Dunlap. * Add my email address to copyright and MODULE_AUTHOR lines, per Randy Dunlap. * Document the reference counting behaviour more clearly, per Greg Kroah-Hartman. * Hopefully submit all the patches this time the right way. * Link to v1: https://lore.kernel.org/lkml/20240214233645.9273-1-zfigura@codeweavers.com/ * Link to RFC v2: https://lore.kernel.org/lkml/20240131021356.10322-1-zfigura@codeweavers.com/ * Link to RFC v1: https://lore.kernel.org/lkml/20240124004028.16826-1-zfigura@codeweavers.com/ Elizabeth Figura (31): ntsync: Introduce the ntsync driver and character device. ntsync: Introduce NTSYNC_IOC_CREATE_SEM. ntsync: Introduce NTSYNC_IOC_SEM_POST. ntsync: Introduce NTSYNC_IOC_WAIT_ANY. ntsync: Introduce NTSYNC_IOC_WAIT_ALL. ntsync: Introduce NTSYNC_IOC_CREATE_MUTEX. ntsync: Introduce NTSYNC_IOC_MUTEX_UNLOCK. ntsync: Introduce NTSYNC_IOC_MUTEX_KILL. ntsync: Introduce NTSYNC_IOC_CREATE_EVENT. ntsync: Introduce NTSYNC_IOC_EVENT_SET. ntsync: Introduce NTSYNC_IOC_EVENT_RESET. ntsync: Introduce NTSYNC_IOC_EVENT_PULSE. ntsync: Introduce NTSYNC_IOC_SEM_READ. ntsync: Introduce NTSYNC_IOC_MUTEX_READ. ntsync: Introduce NTSYNC_IOC_EVENT_READ. ntsync: Introduce alertable waits. ntsync: Allow waits to use the REALTIME clock. selftests: ntsync: Add some tests for semaphore state. selftests: ntsync: Add some tests for mutex state. selftests: ntsync: Add some tests for NTSYNC_IOC_WAIT_ANY. selftests: ntsync: Add some tests for NTSYNC_IOC_WAIT_ALL. selftests: ntsync: Add some tests for wakeup signaling with WINESYNC_IOC_WAIT_ANY. selftests: ntsync: Add some tests for wakeup signaling with WINESYNC_IOC_WAIT_ALL. selftests: ntsync: Add some tests for manual-reset event state. selftests: ntsync: Add some tests for auto-reset event state. selftests: ntsync: Add some tests for wakeup signaling with events. selftests: ntsync: Add tests for alertable waits. selftests: ntsync: Add some tests for wakeup signaling via alerts. selftests: ntsync: Add a stress test for contended waits. maintainers: Add an entry for ntsync. docs: ntsync: Add documentation for the ntsync uAPI.

[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.

[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 net-next v2 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, inner_network_header is always set in the receive phase of GRO, this is then leveraged in the next commit to remove some 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…). 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: set inner_network_header in receive phase 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 | 33 ++++++---- 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 | 9 ++- net/core/gro.c | 5 +- net/ethernet/eth.c | 5 +- net/ipv4/af_inet.c | 53 ++------------- net/ipv4/fou_core.c | 9 +-- net/ipv4/gre_offload.c | 6 +- net/ipv4/tcp_offload.c | 80 ++++++++++++++++++----- net/ipv4/udp.c | 3 +- net/ipv4/udp_offload.c | 26 ++++---- net/ipv6/ip6_offload.c | 45 +++++-------- 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, 188 insertions(+), 162 deletions(-) -- 2.36.1
