[PATCH bpf-next,v5 0/4] xfrm: interface: Add unstable helpers for XFRM metadata

by Eyal Birger

This patch series adds xfrm metadata helpers using the unstable kfunc call interface for the TC-BPF hooks. This allows steering traffic towards different IPsec connections based on logic implemented in bpf programs. The helpers are integrated into the xfrm_interface module. For this purpose the main functionality of this module is moved to xfrm_interface_core.c. --- changes in v5: - avoid cleanup of percpu dsts as detailed in patch 2 changes in v3: - tag bpf-next tree instead of ipsec-next - add IFLA_XFRM_COLLECT_METADATA sync patch Eyal Birger (4): xfrm: interface: rename xfrm_interface.c to xfrm_interface_core.c xfrm: interface: Add unstable helpers for setting/getting XFRM metadata from TC-BPF tools: add IFLA_XFRM_COLLECT_METADATA to uapi/linux/if_link.h selftests/bpf: add xfrm_info tests include/net/dst_metadata.h | 1 + include/net/xfrm.h | 15 + net/core/dst.c | 8 +- net/core/filter.c | 4 + net/xfrm/Makefile | 8 + net/xfrm/xfrm_interface_bpf.c | 117 ++++++ ...xfrm_interface.c => xfrm_interface_core.c} | 14 + tools/include/uapi/linux/if_link.h | 1 + tools/testing/selftests/bpf/DENYLIST.s390x | 1 + tools/testing/selftests/bpf/config | 2 + .../selftests/bpf/prog_tests/xfrm_info.c | 365 ++++++++++++++++++ .../selftests/bpf/progs/bpf_tracing_net.h | 3 + tools/testing/selftests/bpf/progs/xfrm_info.c | 35 ++ 13 files changed, 572 insertions(+), 2 deletions(-) create mode 100644 net/xfrm/xfrm_interface_bpf.c rename net/xfrm/{xfrm_interface.c => xfrm_interface_core.c} (98%) create mode 100644 tools/testing/selftests/bpf/prog_tests/xfrm_info.c create mode 100644 tools/testing/selftests/bpf/progs/xfrm_info.c -- 2.34.1

[PATCH v2] selftests/tls: Fix tls selftests dependency to correct algorithm

by Tianjia Zhang

Commit d2825fa9365d ("crypto: sm3,sm4 - move into crypto directory") moves SM3 and SM4 algorithm implementations from stand-alone library to crypto API. The corresponding configuration options for the API version (generic) are CONFIG_CRYPTO_SM3_GENERIC and CONFIG_CRYPTO_SM4_GENERIC, respectively. Replace option selected in selftests configuration from the library version to the API version.

[PATCH v3] mm/memfd: MFD_NOEXEC_SEAL and MFD_EXEC

by jeffxu＠chromium.org

From: Jeff Xu <jeffxu(a)chromium.org> Since Linux introduced the memfd feature, memfd have always had their execute bit set, and the memfd_create() syscall doesn't allow setting it differently. However, in a secure by default system, such as ChromeOS, (where all executables should come from the rootfs, which is protected by Verified boot), this executable nature of memfd opens a door for NoExec bypass and enables “confused deputy attack”. E.g, in VRP bug [1]: cros_vm process created a memfd to share the content with an external process, however the memfd is overwritten and used for executing arbitrary code and root escalation. [2] lists more VRP in this kind. On the other hand, executable memfd has its legit use, runc uses memfd’s seal and executable feature to copy the contents of the binary then execute them, for such system, we need a solution to differentiate runc's use of executable memfds and an attacker's [3]. To address those above, this set of patches add following: 1> Let memfd_create() set X bit at creation time. 2> Let memfd to be sealed for modifying X bit. 3> A new pid namespace sysctl: vm.memfd_noexec to control behavior of X bit. For example, if a container has vm.memfd_noexec=2, then memfd_create() without MFD_NOEXEC_SEAL will be rejected. 4> A new security hook in memfd_create(). This make it possible to a new LSM, which rejects or allows executable memfd based on its security policy. This is V3 version of patch: see [4] [5] for previous versions.

[PATCH v1 0/6] kselftest/alsa: pcm-test improvements

by Mark Brown

This series provides a bunch of quick updates which should make the coverage from pcm-test a bit more useful, it adds some support for skipping tests when the hardware/driver is unable to support the requested configuration and then expands the set of cases we cover to include more sample rates and channel counts. This should exercise switching between 8kHz and 44.1kHz based rates and ensure that clocking doesn't get confused by non-stereo channel counts, both of which are I expect common real world errors, at least for embedded cards. Mark Brown (6): kselftest/alsa: Refactor pcm-test to list the tests to run in a struct kselftest/alsa: Report failures to set the requested sample rate as skips kselftest/alsa: Report failures to set the requested channels as skips kselftest/alsa: Don't any configuration in the sample config kselftest/alsa: Provide more meaningful names for tests kselftest/alsa: Add more coverage of sample rates and channel counts .../alsa/conf.d/Lenovo_ThinkPad_P1_Gen2.conf | 35 ++++---- tools/testing/selftests/alsa/pcm-test.c | 88 +++++++++++++------ 2 files changed, 81 insertions(+), 42 deletions(-) base-commit: 1d8025ec722d5e011f9299c46274eb21fb54a428 -- 2.30.2

[PATCH v2 0/3] kselftest/arm64: fp-stress performance improvements

This series contains a few improvements to fp-stress performance, only noticable on emulated platforms which both run more slowly and are stressed far more by fp-stress due to supporting more VLs for SVE and SME. The bulk of the improvement comes from the first patch which reduces the amount of time the main fp-stress executable is swamped by load from the child processes during startup, the other two patches are much more marginal. v2: - Rebase onto arm64/for-next/selftests Mark Brown (3): kselftest/arm64: Hold fp-stress children until they're all spawned kselftest/arm64: Don't drain output while spawning children kselftest/arm64: Allow epoll_wait() to return more than one result tools/testing/selftests/arm64/fp/fp-stress.c | 74 +++++++++++++++----- 1 file changed, 57 insertions(+), 17 deletions(-) base-commit: 642978981ec8a79da00828c696c58b3732b993a6 -- 2.30.2

[PATCH net-next 00/11] mptcp: PM listener events + selftests cleanup

by Matthieu Baerts

Thanks to the patch 6/11, the MPTCP path manager now sends Netlink events when MPTCP listening sockets are created and closed. The reason why it is needed is explained in the linked ticket [1]: MPTCP for Linux, when not using the in-kernel PM, depends on the userspace PM to create extra listening sockets before announcing addresses and ports. Let's call these "PM listeners". With the existing MPTCP netlink events, a userspace PM can create PM listeners at startup time, or in response to an incoming connection. Creating sockets in response to connections is not optimal: ADD_ADDRs can't be sent until the sockets are created and listen()ed, and if all connections are closed then it may not be clear to the userspace PM daemon that PM listener sockets should be cleaned up. Hence this feature request: to add MPTCP netlink events for listening socket close & create, so PM listening sockets can be managed based on application activity. [1] https://github.com/multipath-tcp/mptcp_net-next/issues/313 Selftests for these new Netlink events have been added in patches 9,11/11. The remaining patches introduce different cleanups and small improvements in MPTCP selftests to ease the maintenance and the addition of new tests.

[PATCH v3 0/9] KVM: s390: Extend MEM_OP ioctl by storage key checked cmpxchg

by Janis Schoetterl-Glausch

User space can use the MEM_OP ioctl to make storage key checked reads and writes to the guest, however, it has no way of performing atomic, key checked, accesses to the guest. Extend the MEM_OP ioctl in order to allow for this, by adding a cmpxchg mode. For now, support this mode for absolute accesses only. This mode can be use, for example, to set the device-state-change indicator and the adapter-local-summary indicator atomically. Also contains some fixes/changes for the memop selftest independent of the cmpxchg changes. v2 -> v3 * rebase onto the wip/cmpxchg_user_key branch in the s390 kernel repo * use __uint128_t instead of unsigned __int128 * put moving of testlist into main into separate patch * pick up R-b's (thanks Nico) v1 -> v2 * get rid of xrk instruction for cmpxchg byte and short implementation * pass old parameter via pointer instead of in mem_op struct * indicate failure of cmpxchg due to wrong old value by special return code * picked up R-b's (thanks Thomas) Janis Schoetterl-Glausch (9): KVM: s390: Extend MEM_OP ioctl by storage key checked cmpxchg Documentation: KVM: s390: Describe KVM_S390_MEMOP_F_CMPXCHG KVM: s390: selftest: memop: Pass mop_desc via pointer KVM: s390: selftest: memop: Replace macros by functions KVM: s390: selftest: memop: Move testlist into main KVM: s390: selftest: memop: Add cmpxchg tests KVM: s390: selftest: memop: Add bad address test KVM: s390: selftest: memop: Fix typo KVM: s390: selftest: memop: Fix wrong address being used in test Documentation/virt/kvm/api.rst | 21 +- include/uapi/linux/kvm.h | 5 + arch/s390/kvm/gaccess.h | 3 + arch/s390/kvm/gaccess.c | 101 ++++ arch/s390/kvm/kvm-s390.c | 35 +- tools/testing/selftests/kvm/s390x/memop.c | 670 +++++++++++++++++----- 6 files changed, 683 insertions(+), 152 deletions(-) Range-diff against v2: 1: c6731b0063ab ! 1: 94820a73e9b0 KVM: s390: Extend MEM_OP ioctl by storage key checked cmpxchg @@ arch/s390/kvm/gaccess.h: int access_guest_with_key(struct kvm_vcpu *vcpu, unsign void *data, unsigned long len, enum gacc_mode mode);

[PATCH v3 0/7] kselftest/alsa: pcm-test improvements

by Mark Brown

This series provides a bunch of quick updates which should make the coverage from pcm-test a bit more useful, it adds some support for skipping tests when the hardware/driver is unable to support the requested configuration, support for providing user visible descriptions and then expands the set of cases we cover to include more sample rates and channel counts. This should exercise switching between 8kHz and 44.1kHz based rates and ensure that clocking doesn't get confused by non-stereo channel counts, both of which are I expect common real world errors, at least for embedded cards. v3: - "Rebase" onto Takashi's current tree (with a revert). - Include Jaroslav's changes to specify all tests in the configuration file parsing. - Add a new "description" field to the configuration instead of trying to name the tests. - Always run both default and per-system tests, logging our success at setting the per-system configurations as a separate test since they shouldn't fail. v2: - Rebase onto Takashi's current tree. - Tweak the buffer sizes for the newly added cases, don't be quite so ambitious in how big a buffer we request for 96kHz and don't go quite so small for 8kHz since some devices start hitting lower limits on period size and struggle to deliver accurate timing. Jaroslav Kysela (1): kselftest/alsa: pcm - move more configuration to configuration files Mark Brown (6): kselftest/alsa: pcm - Drop recent coverage improvement changes kselftest/alsa: pcm - Always run the default set of tests kselftest/alsa: pcm - skip tests when we fail to set params kselftest/alsa: pcm - Support optional description for tests kselftest/alsa: pcm - Provide descriptions for the default tests kselftest/alsa: pcm - Add more coverage by default tools/testing/selftests/alsa/Makefile | 2 +- tools/testing/selftests/alsa/alsa-local.h | 3 + tools/testing/selftests/alsa/conf.c | 26 ++- .../alsa/conf.d/Lenovo_ThinkPad_P1_Gen2.conf | 43 ++-- tools/testing/selftests/alsa/pcm-test.c | 205 ++++++++++++------ tools/testing/selftests/alsa/pcm-test.conf | 63 ++++++ 6 files changed, 250 insertions(+), 92 deletions(-) create mode 100644 tools/testing/selftests/alsa/pcm-test.conf base-commit: 7d721baea138696d5a6746fb5bce0a510a91bd65 -- 2.30.2

[PATCH bpf-next,v3 0/4] xfrm: interface: Add unstable helpers for XFRM metadata

by Eyal Birger

[PATCH] kselftests/alsa: pcm - move more configuration to configuration files

by Jaroslav Kysela

Obtain all test parameters from the configuration files. The defaults are defined in the pcm-test.conf file. The test count and parameters may be variable per specific hardware. Also, handle alt_formats field now (with the fixes in the format loop). It replaces the original "automatic" logic which is not so universal. The code may be further extended to skip various tests based on the configuration hints, if the exact PCM hardware parameters are not available for the given hardware.

[PATCH] Documentation: kunit: Fix "How Do I Use This" / "Next Steps" sections

by David Gow

The 'index' and 'start' pages end with very similar "How Do I Use This" / "Next Steps" sections respectively, which link to the other documentation pages. This wasn't updated when the tips.rst page was removed. Remove the reference to tips.rst, as well as tidy up the descriptions on all of the links (especially given that sphinx gives the page titles anyway.

[PATCH v2 0/6] kselftest/alsa: pcm-test improvements

by Mark Brown

This series provides a bunch of quick updates which should make the coverage from pcm-test a bit more useful, it adds some support for skipping tests when the hardware/driver is unable to support the requested configuration and then expands the set of cases we cover to include more sample rates and channel counts. This should exercise switching between 8kHz and 44.1kHz based rates and ensure that clocking doesn't get confused by non-stereo channel counts, both of which are I expect common real world errors, at least for embedded cards. v2: - Rebase onto Takashi's current tree. - Tweak the buffer sizes for the newly added cases, don't be quite so ambitious in how big a buffer we request for 96kHz and don't go quite so small for 8kHz since some devices start hitting lower limits on period size and struggle to deliver accurate timing. Mark Brown (6): kselftest/alsa: Refactor pcm-test to list the tests to run in a struct kselftest/alsa: Report failures to set the requested sample rate as skips kselftest/alsa: Report failures to set the requested channels as skips kselftest/alsa: Don't any configuration in the sample config kselftest/alsa: Provide more meaningful names for tests kselftest/alsa: Add more coverage of sample rates and channel counts .../alsa/conf.d/Lenovo_ThinkPad_P1_Gen2.conf | 35 ++++---- tools/testing/selftests/alsa/pcm-test.c | 88 +++++++++++++------ 2 files changed, 81 insertions(+), 42 deletions(-) base-commit: 2133dc91d6658242009177b564ac47c49e08668a -- 2.30.2

[PATCH] selftests/damon: test removed scheme sysfs dir access bug

by SeongJae Park

A DAMON sysfs user could start DAMON with a scheme, remove the sysfs directory for the scheme, and then ask stats or schemes tried regions update. The related logic were not aware of the already removed directory situation, so it was able to results in invalid memory accesses. The fix has made with commit 8468b486612c ("mm/damon/sysfs-schemes: skip stats update if the scheme directory is removed"), though. Add a selftest to avoid such kind of bugs be introduced again.

For example you could define an enum vc4_pixelvalve type and have something like the following: const struct vc4_pv_data *vc4_crtc_get_pixelvalve_data(enum vc4_pixelvalve pv); All these are small nits though, the patch looks great to me and I think is awesome to have this level of testing with KUnit.

So that including it in drivers will be a no-op. Or do you plan to conditionally include this header file in drivers? So that is only included when CONFIG_DRM_KUNIT_TEST is enabled? Another thing that wondered is if we want a different namespace for this header, i.e: <drm/testing/drm_kunit_helpers.h>, to make it clear that is not part of the DRM API but just for testing helpers.

[PATCH ipsec-next 0/3] xfrm: interface: Add unstable helpers for XFRM metadata

by Eyal Birger

This patch series adds xfrm metadata helpers using the unstable kfunc call interface for the TC-BPF hooks. This allows steering traffic towards different IPsec connections based on logic implemented in bpf programs. The helpers are integrated into the xfrm_interface module. For this purpose the main functionality of this module is moved to xfrm_interface_core.c. Eyal Birger (3): xfrm: interface: rename xfrm_interface.c to xfrm_interface_core.c xfrm: interface: Add unstable helpers for setting/getting XFRM metadata from TC-BPF selftests/bpf: add xfrm_info tests include/net/dst_metadata.h | 1 + include/net/xfrm.h | 20 + net/core/dst.c | 4 + net/xfrm/Makefile | 8 + net/xfrm/xfrm_interface_bpf.c | 92 +++++ ...xfrm_interface.c => xfrm_interface_core.c} | 15 + tools/testing/selftests/bpf/config | 2 + .../selftests/bpf/prog_tests/test_xfrm_info.c | 342 ++++++++++++++++++ .../selftests/bpf/progs/test_xfrm_info_kern.c | 74 ++++ 9 files changed, 558 insertions(+) create mode 100644 net/xfrm/xfrm_interface_bpf.c rename net/xfrm/{xfrm_interface.c => xfrm_interface_core.c} (98%) create mode 100644 tools/testing/selftests/bpf/prog_tests/test_xfrm_info.c create mode 100644 tools/testing/selftests/bpf/progs/test_xfrm_info_kern.c -- 2.34.1

[RFC PATCH v2 00/11] implement DAMOS filtering for anon pages and

by SeongJae Park

Changes from RFC v1 (https://lore.kernel.org/damon/20221124212114.136863-1-sj@kernel.org/) - sysfs: Clean up filters directory from scheme directory cleanup path - sysfs: Link newly created filter to the scheme - sysfs: Ignore removed memcg when checking path - sysfs: Guard 'struct mem_cgroup' access with CONFIG_MEMCG (kernel test robot) ---- DAMOS let users do system operations in a data access pattern oriented way. The data access pattern, which is extracted by DAMON, is somewhat accurate more than what user space could know in many cases. However, in some situation, users could know something more than the kernel about the pattern or some special requirements for some types of memory or processes. For example, some users would have slow swap devices and knows latency-ciritical processes and therefore want to use DAMON-based proactive reclamation (DAMON_RECLAIM) for only non-anonymous pages of non-latency-critical processes. For such restriction, users could exclude the memory regions from the initial monitoring regions and use non-dynamic monitoring regions update monitoring operations set including fvaddr and paddr. They could also adjust the DAMOS target access pattern. For dynamically changing memory layout and access pattern, those would be not enough. To help the case, add an interface, namely DAMOS filters, which can be used to avoid the DAMOS actions be applied to specific types of memory, to DAMON kernel API (damon.h). At the moment, it supports filtering anonymous pages and/or specific memory cgroups in or out for each DAMOS scheme. This patchset adds the support for all DAMOS actions that 'paddr' monitoring operations set supports ('pageout', 'lru_prio', and 'lru_deprio'), and the functionality is exposed via DAMON kernel API (damon.h) the DAMON sysfs interface (/sys/kernel/mm/damon/admins/), and DAMON_RECLAIM module parameters. Patches Sequence ---------------- First patch implements DAMOS filter interface to DAMON kernel API. Second patch makes the physical address space monitoring operations set to support the filters from all supporting DAMOS actions. Third patch adds anonymous pages filter support to DAMON_RECLAIM, and the fourth patch documents the DAMON_RECLAIM's new feature. Fifth to seventh patches implement DAMON sysfs files for support of the filters, and eighth patch connects the file to use DAMOS filters feature. Ninth patch adds simple self test cases for DAMOS filters of the sysfs interface. Finally, following two patches (tenth and eleventh) document the new features and interfaces. SeongJae Park (11): mm/damon/core: implement damos filter mm/damon/paddr: support DAMOS filters mm/damon/reclaim: add a parameter called skip_anon for avoiding anonymous pages reclamation Docs/admin-guide/damon/reclaim: document 'skip_anon' parameter mm/damon/sysfs-schemes: implement filters directory mm/damon/sysfs-schemes: implement filter directory mm/damon/sysfs-schemes: connect filter directory and filters directory mm/damon/sysfs-schemes: implement scheme filters selftests/damon/sysfs: test filters directory Docs/admin-guide/mm/damon/usage: document DAMOS filters of sysfs Docs/ABI/damon: document scheme filters files .../ABI/testing/sysfs-kernel-mm-damon | 29 ++ .../admin-guide/mm/damon/reclaim.rst | 9 + Documentation/admin-guide/mm/damon/usage.rst | 48 ++- include/linux/damon.h | 51 +++ mm/damon/core.c | 39 ++ mm/damon/paddr.c | 71 +++- mm/damon/reclaim.c | 19 + mm/damon/sysfs-schemes.c | 370 +++++++++++++++++- tools/testing/selftests/damon/sysfs.sh | 29 ++ 9 files changed, 652 insertions(+), 13 deletions(-) -- 2.25.1

That is, just define the simpler macros when is disabled? The kunit_fail_current_test() is just a no-op if CONFIG_KUNIT isn't enabled, but I think my question still stands.

[PATCH net-next 0/8] mptcp: MSG_FASTOPEN and TFO listener side support

by Matthieu Baerts

Before this series, only the initiator of a connection was able to combine both TCP FastOpen and MPTCP when using TCP_FASTOPEN_CONNECT socket option. These new patches here add (in theory) the full support of TFO with MPTCP, which means: - MSG_FASTOPEN sendmsg flag support (patch 1/8) - TFO support for the listener side (patches 2-5/8) - TCP_FASTOPEN socket option (patch 6/8) - TCP_FASTOPEN_KEY socket option (patch 7/8) To support TFO for the server side, a few preparation patches are needed (patches 2 to 5/8). Some of them were inspired by a previous work from Benjamin Hesmans. Note that TFO support with MPTCP has been validated with selftests (patch 8/8) but also with Packetdrill tests running with a modified but still very WIP version supporting MPTCP. Both the modified tool and the tests are available online: https://github.com/multipath-tcp/packetdrill/ Dmytro Shytyi (5): mptcp: add MSG_FASTOPEN sendmsg flag support mptcp: implement delayed seq generation for passive fastopen mptcp: add subflow_v(4,6)_send_synack() mptcp: add TCP_FASTOPEN sock option selftests: mptcp: mptfo Initiator/Listener Matthieu Baerts (1): mptcp: add support for TCP_FASTOPEN_KEY sockopt Paolo Abeni (2): mptcp: track accurately the incoming MPC suboption type mptcp: consolidate initial ack seq generation net/mptcp/Makefile | 2 +- net/mptcp/fastopen.c | 73 ++++++++ net/mptcp/options.c | 25 ++- net/mptcp/protocol.c | 39 +--- net/mptcp/protocol.h | 28 ++- net/mptcp/sockopt.c | 9 +- net/mptcp/subflow.c | 105 ++++++++--- .../selftests/net/mptcp/mptcp_connect.c | 171 +++++++++++++----- .../selftests/net/mptcp/mptcp_connect.sh | 21 +++ 9 files changed, 358 insertions(+), 115 deletions(-) create mode 100644 net/mptcp/fastopen.c Cc: Benjamin Hesmans <benjamin.hesmans(a)tessares.net> base-commit: a6e3d86ece0b42a571a11055ace5c3148cb7ce76 -- 2.37.2

We print the "test log" on failure. This is meant to be all the kernel output that happened during the test. But we also include the special KTAP lines in it, which are often redundant.

[PATCH v1 0/3] kselftest/arm64: fp-stress performance improvements

by Mark Brown

This series contains a few improvements to fp-stress performance, only noticable on emulated platforms which both run more slowly and are stressed far more by fp-stress due to supporting more VLs for SVE and SME. The bulk of the improvement comes from the first patch which reduces the amount of time the main fp-stress executable is swamped by load from the child processes during startup, the other two patches are much more marginal. Mark Brown (3): kselftest/arm64: Hold fp-stress children until they're all spawned kselftest/arm64: Don't drain output while spawning children kselftest/arm64: Allow epoll_wait() to return more than one result tools/testing/selftests/arm64/fp/fp-stress.c | 74 +++++++++++++++----- 1 file changed, 57 insertions(+), 17 deletions(-) base-commit: a711987490a1784c3e3fd6d752a63501c11eb80b -- 2.30.2
