[PATCH net-next v9 0/3] net: gro: remove network_header use, move p->{flush/flush_id} calculations to L4

by Richard Gobert

The cb fields network_offset and inner_network_offset are used instead of skb->network_header throughout GRO. These fields are 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. These fields are checked in L4 instead. 3rd patch adds tests for different flush_id flows in GRO. v8 -> v9: - rename skb_gro_network_offset to skb_gro_receive_network_offset for clarification - improved code readability in tests and gro_network_flush functions - v8: https://lore.kernel.org/all/20240506093550.128210-1-richardbgobert@gmail.co… v7 -> v8: - Remove network_header use in gro - Re-send commits after the dependent patch to net was applied - v7: https://lore.kernel.org/all/20240412155533.115507-1-richardbgobert@gmail.co… v6 -> v7: - Moved bug fixes to a separate submission in net - Added UDP fwd benchmark - v6: https://lore.kernel.org/all/20240410153423.107381-1-richardbgobert@gmail.co… v5 -> v6: - Write inner_network_offset in vxlan and geneve - Ignore is_atomic when DF=0 - v5: https://lore.kernel.org/all/20240408141720.98832-1-richardbgobert@gmail.com/ v4 -> v5: - Add 1st commit - flush id checks in udp_gro_receive segment which can be backported by itself - Add TCP measurements for the 5th commit - Add flush id tests to ensure flush id logic is preserved in GRO - Simplify gro_inet_flush by removing a branch - v4: https://lore.kernel.org/all/202420325182543.87683-1-richardbgobert@gmail.co… v3 -> v4: - Fix code comment and commit message typos - v3: https://lore.kernel.org/all/f939c84a-2322-4393-a5b0-9b1e0be8ed8e@gmail.com/ v2 -> v3: - Use napi_gro_cb instead of skb->{offset} - v2: https://lore.kernel.org/all/2ce1600b-e733-448b-91ac-9d0ae2b866a4@gmail.com/ 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 (3): net: gro: use cb instead of skb->network_header net: gro: move L3 flush checks to tcp_gro_receive and udp_gro_receive_segment selftests/net: add flush id selftests include/net/gro.h | 87 ++++++++++++++++--- net/core/gro.c | 3 - net/ipv4/af_inet.c | 45 +--------- net/ipv4/tcp_offload.c | 20 ++--- net/ipv4/udp_offload.c | 10 +-- net/ipv6/ip6_offload.c | 16 +--- net/ipv6/tcpv6_offload.c | 3 +- tools/testing/selftests/net/gro.c | 138 ++++++++++++++++++++++++++++++ 8 files changed, 227 insertions(+), 95 deletions(-) -- 2.36.1

[PATCH] selftests/resctrl: fix clang build warnings related to abs(), labs() calls

by John Hubbard

When building with clang, via: make LLVM=1 -C tools/testing/selftests ...two types of warnings occur: warning: absolute value function 'abs' given an argument of type 'long' but has parameter of type 'int' which may cause truncation of value warning: taking the absolute value of unsigned type 'unsigned long' has no effect Fix these by: a) using labs() in place of abs(), when long integers are involved, and b) Change to use signed integer data types, in places where subtraction is used (and could end up with negative values). c) Remove a duplicate abs() call in cmt_test.c.

[PATCH v2 0/2] Selftests: Fix compilation warnings due to missing _GNU_SOURCE definition

by Tao Su

Since kselftest_harness.h introduces asprintf()[1], many selftests have compilation warnings or errors due to missing _GNU_SOURCE definitions. The issue stems from a lack of a LINE_MAX definition in Android (see commit 38c957f07038), which is the reason why asprintf() was introduced. We tried adding _GNU_SOURCE definitions to more selftests to fix, but asprintf() may continue to cause problems, and since it is quite late in the 6.9 cycle, we would like to revert 809216233555 first to provide testing for forks[2].

[PATCH v2] selftests/mqueue: fix 5 warnings about signed/unsigned mismatches

by John Hubbard

When building with clang, via: make LLVM=1 -C tools/testing/selftest ...clang warns about several cases of using a signed integer for the priority argument to mq_receive(3), which expects an unsigned int. Fix this by declaring the type as unsigned int in all cases. Also, both input and output priority are unsigned, per the man pages, so let's change the type of both priorities throughout, even though clang did not warn about the prio_out variable. Also, add an argument name to test->func(), in order to address another warning from clang.

[PATCH net] selftests: net: avoid waiting for server in amt.sh forever when it fails.

by Taehee Yoo

In the forwarding testcase, it opens a server and a client with the nc. The server receives the correct message from NC, it prints OK. The server prints FAIL if it receives the wrong message from the client. But If the server can't receive any message, it will not close so the amt.sh waits forever. There are several reasons. 1. crash of smcrouted. 2. Send a message from the client to the server before the server is up. To avoid this problem, the server waits only for 10 seconds. The client sends messages for 10 seconds. If the server is successfully closed, it kills the client.

[PATCH v4 0/9] Support Zve32[xf] and Zve64[xfd] Vector subextensions

by Andy Chiu

The series composes of two parts. The first part provides a quick fix for the issue on a recent thread[1]. The issue happens when a platform has ununified vector register length across multiple cores. Specifically, patch 1 adds a comment at a callsite of riscv_setup_vsize to clarify how vlenb is observed by the system. Patch 2 fixes the issue by failing the boot process of a secondary core if vlenb mismatches. The second part of the series provide a finer grain view of the Vector extension. Patch 3 give the obsolete ISA parser the ability to expand ISA extensions for sigle letter extensions. Patch 3, 4 introduces Zve32x, Zve32f, Zve64x, Zve64f, Zve64d for isa parsing and hwprobe. Patch 5 updates all callsites such that Vector subextensions are maximumly supported by the kernel. Two parts of the series are sent together to ease the effort of picking dependency patches. The first part can be merged independent of the second one if necessary. The series is tested on a QEMU and verified that booting, Vector programs context-switch, signal, ptrace, prctl interfaces works when we only report partial V from the ISA. Note that the signal test was performed after applying the commit c27fa53b858b ("riscv: Fix vector state restore in rt_sigreturn()") This patch should be able to apply on risc-v for-next branch on top of the commit ba5ea59f768f ("riscv: Do not save the scratch CSR during suspend") [1]: https://lore.kernel.org/all/20240228-vicinity-cornstalk-4b8eb5fe5730@spud/T… Changes in v4: - Add a patch to trigger prctl test on ZVE32X (9) - Add a patch to fix integer promotion bug in hwprobe (8) - Fix a build fail on !CONFIG_RISCV_ISA_V (7) - Add more comment in the assembly code change (2) - Link to v3: https://lore.kernel.org/r/20240318-zve-detection-v3-0-e12d42107fa8@sifive.c… Changelog v3: - Include correct maintainers and mailing list into CC. - Cleanup isa string parser code (3) - Adjust extensions order and name (4, 5) - Refine commit message (6) Changelog v2: - Update comments and commit messages (1, 2, 7) - Refine isa_exts[] lists for zve extensions (4) - Add a patch for dt-binding (5) - Make ZVE* extensions depend on has_vector(ZVE32X) (6, 7) --- --- Andy Chiu (9): riscv: vector: add a comment when calling riscv_setup_vsize() riscv: smp: fail booting up smp if inconsistent vlen is detected riscv: cpufeature: call match_isa_ext() for single-letter extensions riscv: cpufeature: add zve32[xf] and zve64[xfd] isa detection dt-bindings: riscv: add Zve32[xf] Zve64[xfd] ISA extension description riscv: hwprobe: add zve Vector subextensions into hwprobe interface riscv: vector: adjust minimum Vector requirement to ZVE32X hwprobe: fix integer promotion in RISCV_HWPROBE_EXT macro selftest: run vector prctl test for ZVE32X Documentation/arch/riscv/hwprobe.rst | 15 ++++++ .../devicetree/bindings/riscv/extensions.yaml | 30 ++++++++++++ arch/riscv/include/asm/hwcap.h | 5 ++ arch/riscv/include/asm/switch_to.h | 2 +- arch/riscv/include/asm/vector.h | 25 ++++++---- arch/riscv/include/asm/xor.h | 2 +- arch/riscv/include/uapi/asm/hwprobe.h | 7 ++- arch/riscv/kernel/cpufeature.c | 56 ++++++++++++++++++---- arch/riscv/kernel/head.S | 19 +++++--- arch/riscv/kernel/kernel_mode_vector.c | 4 +- arch/riscv/kernel/process.c | 4 +- arch/riscv/kernel/signal.c | 6 +-- arch/riscv/kernel/smpboot.c | 14 ++++-- arch/riscv/kernel/sys_hwprobe.c | 13 ++++- arch/riscv/kernel/vector.c | 15 +++--- arch/riscv/lib/uaccess.S | 2 +- .../testing/selftests/riscv/vector/vstate_prctl.c | 6 +-- 17 files changed, 174 insertions(+), 51 deletions(-) --- base-commit: ba5ea59f768f67d127b319b26ba209ff67e0d9a5 change-id: 20240318-zve-detection-50106d2da527 Best regards, -- Andy Chiu <andy.chiu(a)sifive.com>

[PATCH REPOST net-next v3] selftest: epoll_busy_poll: epoll busy poll tests

by Joe Damato

Add a simple test for the epoll busy poll ioctls, using the kernel selftest harness. This test ensures that the ioctls have the expected return codes and that the kernel properly gets and sets epoll busy poll parameters. The test can be expanded in the future to do real busy polling (provided another machine to act as the client is available). Signed-off-by: Joe Damato <jdamato(a)fastly.com> --- v2 -> v3: - Added this changelog :) - Add libcap to LDLIBS. - Most other changes are in test_set_invalid: - Check if CAP_NET_ADMIN is set in the effective set before setting busy_poll_budget over NAPI_POLL_WEIGHT. The test which follows assumes CAP_NET_ADMIN. - Drop CAP_NET_ADMIN from effective set in order to ensure the ioctl fails when busy_poll_budget exceeds NAPI_POLL_WEIGHT. - Put CAP_NET_ADMIN back into the effective set afterwards. - Changed self->params.busy_poll_budget from 65535 to UINT16_MAX. - Changed the cast for params.busy_poll_usecs from unsigned int to uint32_t in the test_set_invalid case. v1 -> v2: - Rewrote completely to use kernel self test harness. tools/testing/selftests/net/.gitignore | 1 + tools/testing/selftests/net/Makefile | 3 +- tools/testing/selftests/net/epoll_busy_poll.c | 320 ++++++++++++++++++ 3 files changed, 323 insertions(+), 1 deletion(-) create mode 100644 tools/testing/selftests/net/epoll_busy_poll.c diff --git a/tools/testing/selftests/net/.gitignore b/tools/testing/selftests/net/.gitignore index d996a0ab0765..777cfd027076 100644 --- a/tools/testing/selftests/net/.gitignore +++ b/tools/testing/selftests/net/.gitignore @@ -5,6 +5,7 @@ bind_wildcard csum cmsg_sender diag_uid +epoll_busy_poll fin_ack_lat gro hwtstamp_config diff --git a/tools/testing/selftests/net/Makefile b/tools/testing/selftests/net/Makefile index 5befca249452..c6112d08b233 100644 --- a/tools/testing/selftests/net/Makefile +++ b/tools/testing/selftests/net/Makefile @@ -67,7 +67,7 @@ TEST_GEN_FILES += ipsec TEST_GEN_FILES += ioam6_parser TEST_GEN_FILES += gro TEST_GEN_PROGS = reuseport_bpf reuseport_bpf_cpu reuseport_bpf_numa -TEST_GEN_PROGS += reuseport_dualstack reuseaddr_conflict tls tun tap +TEST_GEN_PROGS += reuseport_dualstack reuseaddr_conflict tls tun tap epoll_busy_poll TEST_GEN_FILES += toeplitz TEST_GEN_FILES += cmsg_sender TEST_GEN_FILES += stress_reuseport_listen @@ -102,6 +102,7 @@ TEST_INCLUDES := forwarding/lib.sh include ../lib.mk +$(OUTPUT)/epoll_busy_poll: LDLIBS += -lcap $(OUTPUT)/reuseport_bpf_numa: LDLIBS += -lnuma $(OUTPUT)/tcp_mmap: LDLIBS += -lpthread -lcrypto $(OUTPUT)/tcp_inq: LDLIBS += -lpthread diff --git a/tools/testing/selftests/net/epoll_busy_poll.c b/tools/testing/selftests/net/epoll_busy_poll.c new file mode 100644 index 000000000000..9dd2830fd67c --- /dev/null +++ b/tools/testing/selftests/net/epoll_busy_poll.c @@ -0,0 +1,320 @@ +// SPDX-License-Identifier: GPL-2.0-or-later + +/* Basic per-epoll context busy poll test. + * + * Only tests the ioctls, but should be expanded to test two connected hosts in + * the future + */ + +#define _GNU_SOURCE + +#include <error.h> +#include <errno.h> +#include <inttypes.h> +#include <limits.h> +#include <stdio.h> +#include <stdlib.h> +#include <string.h> +#include <unistd.h> + +#include <sys/capability.h> + +#include <sys/epoll.h> +#include <sys/ioctl.h> +#include <sys/socket.h> + +#include "../kselftest_harness.h" + +/* if the headers haven't been updated, we need to define some things */ +#if !defined(EPOLL_IOC_TYPE) +struct epoll_params { + uint32_t busy_poll_usecs;

[PATCH] selftests: Add _GNU_SOURCE definition when including kselftest_harness.h

by Tao Su

asprintf() is declared in stdio.h when defining _GNU_SOURCE, but stdio.h is so common that many files don’t define _GNU_SOURCE before including stdio.h, and defining _GNU_SOURCE after including stdio.h will no longer take effect. Since kselftest_harness.h introduces asprintf(), it is necessary to add _GNU_SOURCE definition in all selftests including kselftest_harness.h, otherwise, there will be warnings or even errors during compilation. There are already many selftests that define _GNU_SOURCE or put the include of kselftest_harness.h at the very beginning of the .c file, just add the _GNU_SOURCE definition in the tests that have compilation warnings.

[PATCH v2 0/5] Define _GNU_SOURCE for sources using

by Edward Liaw

809216233555 ("selftests/harness: remove use of LINE_MAX") introduced asprintf into kselftest_harness.h, which is a GNU extension and needs _GNU_SOURCE to either be defined prior to including headers or with the -D_GNU_SOURCE flag passed to the compiler. v1: https://lore.kernel.org/linux-kselftest/20240430235057.1351993-1-edliaw@goo… v2: add -D_GNU_SOURCE to KHDR_INCLUDES so that it is in a single location. Remove #define _GNU_SOURCE from source code to resolve redefinition warnings.

[PATCH] KVM: selftests: Check API version when creating VM

by Ivan Orlov

As it is said in the docs, we should always check the KVM API version before running the KVM-based applications. Add the function which queries the current KVM API version through `ioctl` to the `kvm_util.c` file. Add a new TEST_REQUIRE statement to the `vm_open` function in order to verify the version of the KVM API before creating a VM.

[PATCH v8 0/3] KVM: selftests: aarch64: Introduce pmu_event_filter_test

by Shaoqin Huang

The test is inspired by the pmu_event_filter_test which implemented by x86. On the arm64 platform, there is the same ability to set the pmu_event_filter through the KVM_ARM_VCPU_PMU_V3_FILTER attribute. So add the test for arm64. The series first create the helper function which can be used for the vpmu related tests. Then, it implement the test.

[PATCH v2] kunit: Cover 'assert.c' with tests

by Ivan Orlov

There are multiple assertion formatting functions in the `assert.c` file, which are not covered with tests yet. Implement the KUnit test for these functions. The test consists of 11 test cases for the following functions: 1) 'is_literal' 2) 'is_str_literal' 3) 'kunit_assert_prologue', test case for multiple assert types 4) 'kunit_assert_print_msg' 5) 'kunit_unary_assert_format' 6) 'kunit_ptr_not_err_assert_format' 7) 'kunit_binary_assert_format' 8) 'kunit_binary_ptr_assert_format' 9) 'kunit_binary_str_assert_format' 10) 'kunit_assert_hexdump' 11) 'kunit_mem_assert_format' The test aims at maximizing the branch coverage for the assertion formatting functions. As you can see, it covers some of the static helper functions as well, so mark the static functions in `assert.c` as 'VISIBLE_IF_KUNIT' and conditionally export them with EXPORT_SYMBOL_IF_KUNIT. Add the corresponding definitions to `assert.h`. Build the assert test when CONFIG_KUNIT_TEST is enabled, similar to how it is done for the string stream test. Signed-off-by: Ivan Orlov <ivan.orlov0322(a)gmail.com> --- V1 -> V2: - Check the output from the string stream for containing the key parts instead of comparing the results with expected strings char by char, as it was suggested by Rae Moar <rmoar(a)google.com>. Define two macros to make it possible (ASSERT_TEST_EXPECT_CONTAIN and ASSERT_TEST_EXPECT_NCONTAIN). - Mark the static functions in `assert.c` as VISIBLE_IF_KUNIT and export them conditionally if kunit is enabled instead of including the `assert_test.c` file in the end of `assert.c`. This way we will decouple the test from the implementation (SUT). - Update the kunit_assert_hexdump test: now it checks for presense of the brackets '<>' around the non-matching bytes, instead of comparing the kunit_assert_hexdump output char by char. include/kunit/assert.h | 11 ++ lib/kunit/Makefile | 1 + lib/kunit/assert.c | 24 ++- lib/kunit/assert_test.c | 389 ++++++++++++++++++++++++++++++++++++++++ 4 files changed, 417 insertions(+), 8 deletions(-) create mode 100644 lib/kunit/assert_test.c diff --git a/include/kunit/assert.h b/include/kunit/assert.h index 24c2b9fa61e8..31e655abbce9 100644 --- a/include/kunit/assert.h +++ b/include/kunit/assert.h @@ -218,4 +218,15 @@ void kunit_mem_assert_format(const struct kunit_assert *assert, const struct va_format *message, struct string_stream *stream); +#if IS_ENABLED(CONFIG_KUNIT_TEST) +void kunit_assert_print_msg(const struct va_format *message, + struct string_stream *stream); +bool is_literal(const char *text, long long value); +bool is_str_literal(const char *text, const char *value); +void kunit_assert_hexdump(struct string_stream *stream, + const void *buf, + const void *compared_buf, + const size_t len); +#endif + #endif /* _KUNIT_ASSERT_H */ diff --git a/lib/kunit/Makefile b/lib/kunit/Makefile index 309659a32a78..be7c9903936f 100644 --- a/lib/kunit/Makefile +++ b/lib/kunit/Makefile @@ -18,6 +18,7 @@ endif obj-y += hooks.o obj-$(CONFIG_KUNIT_TEST) += kunit-test.o +obj-$(CONFIG_KUNIT_TEST) += assert_test.o # string-stream-test compiles built-in only. ifeq ($(CONFIG_KUNIT_TEST),y) diff --git a/lib/kunit/assert.c b/lib/kunit/assert.c index dd1d633d0fe2..382eb409d34b 100644 --- a/lib/kunit/assert.c +++ b/lib/kunit/assert.c @@ -7,6 +7,7 @@ */ #include <kunit/assert.h> #include <kunit/test.h> +#include <kunit/visibility.h> #include "string-stream.h" @@ -30,12 +31,14 @@ void kunit_assert_prologue(const struct kunit_loc *loc, } EXPORT_SYMBOL_GPL(kunit_assert_prologue); -static void kunit_assert_print_msg(const struct va_format *message, - struct string_stream *stream) +VISIBLE_IF_KUNIT +void kunit_assert_print_msg(const struct va_format *message, + struct string_stream *stream) { if (message->fmt) string_stream_add(stream, "\n%pV", message); } +EXPORT_SYMBOL_IF_KUNIT(kunit_assert_print_msg); void kunit_fail_assert_format(const struct kunit_assert *assert, const struct va_format *message, @@ -89,7 +92,7 @@ void kunit_ptr_not_err_assert_format(const struct kunit_assert *assert, EXPORT_SYMBOL_GPL(kunit_ptr_not_err_assert_format); /* Checks if `text` is a literal representing `value`, e.g. "5" and 5 */ -static bool is_literal(const char *text, long long value) +VISIBLE_IF_KUNIT bool is_literal(const char *text, long long value) { char *buffer; int len; @@ -110,6 +113,7 @@ static bool is_literal(const char *text, long long value) return ret; } +EXPORT_SYMBOL_IF_KUNIT(is_literal); void kunit_binary_assert_format(const struct kunit_assert *assert, const struct va_format *message, @@ -166,7 +170,7 @@ EXPORT_SYMBOL_GPL(kunit_binary_ptr_assert_format); /* Checks if KUNIT_EXPECT_STREQ() args were string literals. * Note: `text` will have ""s where as `value` will not. */ -static bool is_str_literal(const char *text, const char *value) +VISIBLE_IF_KUNIT bool is_str_literal(const char *text, const char *value) { int len; @@ -178,6 +182,7 @@ static bool is_str_literal(const char *text, const char *value) return strncmp(text + 1, value, len - 2) == 0; } +EXPORT_SYMBOL_IF_KUNIT(is_str_literal); void kunit_binary_str_assert_format(const struct kunit_assert *assert, const struct va_format *message, @@ -208,10 +213,11 @@ EXPORT_SYMBOL_GPL(kunit_binary_str_assert_format); /* Adds a hexdump of a buffer to a string_stream comparing it with * a second buffer.

[RFC PATCH net-next v8 00/14] Device Memory TCP

by Mina Almasry

RFC v8: ======= Major Changes: -------------- - Fixed build error generated by patch-by-patch build. - Applied docs suggestions from Randy. RFC v7: ======= Major Changes: -------------- This revision largely rebases on top of net-next and addresses the feedback RFCv6 received from folks, namely Jakub, Yunsheng, Arnd, David, & Pavel. The series remains in RFC because the queue-API ndos defined in this series are not yet implemented. I have a GVE implementation I carry out of tree for my testing. A upstreamable GVE implementation is in the works. Aside from that, in my estimation all the patches are ready for review/merge. Please do take a look. As usual the full devmem TCP changes including the full GVE driver implementation is here: https://github.com/mina/linux/commits/tcpdevmem-v7/ Detailed changelog: - Use admin-perm in netlink API. - Addressed feedback from Jakub with regards to netlink API implementation. - Renamed devmem.c functions to something more appropriate for that file. - Improve the performance seen through the page_pool benchmark. - Fix the value definition of all the SO_DEVMEM_* uapi. - Various fixes to documentation. Perf - page-pool benchmark: --------------------------- Improved performance of bench_page_pool_simple.ko tests compared to v6: https://pastebin.com/raw/v5dYRg8L net-next base: 8 cycle fast path. RFC v6: 10 cycle fast path. RFC v7: 9 cycle fast path. RFC v7 with CONFIG_DMA_SHARED_BUFFER disabled: 8 cycle fast path, same as baseline. Perf - Devmem TCP benchmark: --------------------- Perf is about the same regardless of the changes in v7, namely the removal of the static_branch_unlikely to improve the page_pool benchmark performance: 189/200gbps bi-directional throughput with RX devmem TCP and regular TCP TX i.e. ~95% line rate. RFC v6: ======= Major Changes: -------------- This revision largely rebases on top of net-next and addresses the little feedback RFCv5 received. The series remains in RFC because the queue-API ndos defined in this series are not yet implemented. I have a GVE implementation I carry out of tree for my testing. A upstreamable GVE implementation is in the works. Aside from that, in my estimation all the patches are ready for review/merge. Please do take a look. As usual the full devmem TCP changes including the full GVE driver implementation is here: https://github.com/mina/linux/commits/tcpdevmem-v6/ This version also comes with some performance data recorded in the cover letter (see below changelog). Detailed changelog: - Rebased on top of the merged netmem_ref changes. - Converted skb->dmabuf to skb->readable (Pavel). Pavel's original suggestion was to remove the skb->dmabuf flag entirely, but when I looked into it closely, I found the issue that if we remove the flag we have to dereference the shinfo(skb) pointer to obtain the first frag to tell whether an skb is readable or not. This can cause a performance regression if it dirties the cache line when the shinfo(skb) was not really needed. Instead, I converted the skb->dmabuf flag into a generic skb->readable flag which can be re-used by io_uring 0-copy RX. - Squashed a few locking optimizations from Eric Dumazet in the RX path and the DEVMEM_DONTNEED setsockopt. - Expanded the tests a bit. Added validation for invalid scenarios and added some more coverage. Perf - page-pool benchmark: --------------------------- bench_page_pool_simple.ko tests with and without these changes: https://pastebin.com/raw/ncHDwAbn AFAIK the number that really matters in the perf tests is the 'tasklet_page_pool01_fast_path Per elem'. This one measures at about 8 cycles without the changes but there is some 1 cycle noise in some results. With the patches this regresses to 9 cycles with the changes but there is 1 cycle noise occasionally running this test repeatedly. Lastly I tried disable the static_branch_unlikely() in netmem_is_net_iov() check. To my surprise disabling the static_branch_unlikely() check reduces the fast path back to 8 cycles, but the 1 cycle noise remains. Perf - Devmem TCP benchmark: --------------------- 189/200gbps bi-directional throughput with RX devmem TCP and regular TCP TX i.e. ~95% line rate. Major changes in RFC v5: ======================== 1. Rebased on top of 'Abstract page from net stack' series and used the new netmem type to refer to LSB set pointers instead of re-using struct page. 2. Downgraded this series back to RFC and called it RFC v5. This is because this series is now dependent on 'Abstract page from net stack'[1] and the queue API. Both are removed from the series to reduce the patch # and those bits are fairly independent or pre-requisite work. 3. Reworked the page_pool devmem support to use netmem and for some more unified handling. 4. Reworked the reference counting of net_iov (renamed from page_pool_iov) to use pp_ref_count for refcounting. The full changes including the dependent series and GVE page pool support is here: https://github.com/mina/linux/commits/tcpdevmem-rfcv5/ [1] https://patchwork.kernel.org/project/netdevbpf/list/?series=810774 Major changes in v1: ==================== 1. Implemented MVP queue API ndos to remove the userspace-visible driver reset. 2. Fixed issues in the napi_pp_put_page() devmem frag unref path. 3. Removed RFC tag. Many smaller addressed comments across all the patches (patches have individual change log). Full tree including the rest of the GVE driver changes: https://github.com/mina/linux/commits/tcpdevmem-v1 Changes in RFC v3: ================== 1. Pulled in the memory-provider dependency from Jakub's RFC[1] to make the series reviewable and mergeable. 2. Implemented multi-rx-queue binding which was a todo in v2. 3. Fix to cmsg handling. The sticking point in RFC v2[2] was the device reset required to refill the device rx-queues after the dmabuf bind/unbind. The solution suggested as I understand is a subset of the per-queue management ops Jakub suggested or similar: https://lore.kernel.org/netdev/20230815171638.4c057dcd@kernel.org/ This is not addressed in this revision, because: 1. This point was discussed at netconf & netdev and there is openness to using the current approach of requiring a device reset. 2. Implementing individual queue resetting seems to be difficult for my test bed with GVE. My prototype to test this ran into issues with the rx-queues not coming back up properly if reset individually. At the moment I'm unsure if it's a mistake in the POC or a genuine issue in the virtualization stack behind GVE, which currently doesn't test individual rx-queue restart. 3. Our usecases are not bothered by requiring a device reset to refill the buffer queues, and we'd like to support NICs that run into this limitation with resetting individual queues. My thought is that drivers that have trouble with per-queue configs can use the support in this series, while drivers that support new netdev ops to reset individual queues can automatically reset the queue as part of the dma-buf bind/unbind. The same approach with device resets is presented again for consideration with other sticking points addressed. This proposal includes the rx devmem path only proposed for merge. For a snapshot of my entire tree which includes the GVE POC page pool support & device memory support: https://github.com/torvalds/linux/compare/master...mina:linux:tcpdevmem-v3 [1] https://lore.kernel.org/netdev/f8270765-a27b-6ccf-33ea-cda097168d79@redhat.… [2] https://lore.kernel.org/netdev/CAHS8izOVJGJH5WF68OsRWFKJid1_huzzUK+hpKbLcL4… Changes in RFC v2: ================== The sticking point in RFC v1[1] was the dma-buf pages approach we used to deliver the device memory to the TCP stack. RFC v2 is a proof-of-concept that attempts to resolve this by implementing scatterlist support in the networking stack, such that we can import the dma-buf scatterlist directly. This is the approach proposed at a high level here[2]. Detailed changes: 1. Replaced dma-buf pages approach with importing scatterlist into the page pool. 2. Replace the dma-buf pages centric API with a netlink API. 3. Removed the TX path implementation - there is no issue with implementing the TX path with scatterlist approach, but leaving out the TX path makes it easier to review. 4. Functionality is tested with this proposal, but I have not conducted perf testing yet. I'm not sure there are regressions, but I removed perf claims from the cover letter until they can be re-confirmed. 5. Added Signed-off-by: contributors to the implementation. 6. Fixed some bugs with the RX path since RFC v1. Any feedback welcome, but specifically the biggest pending questions needing feedback IMO are: 1. Feedback on the scatterlist-based approach in general. 2. Netlink API (Patch 1 & 2). 3. Approach to handle all the drivers that expect to receive pages from the page pool (Patch 6). [1] https://lore.kernel.org/netdev/dfe4bae7-13a0-3c5d-d671-f61b375cb0b4@gmail.c… [2] https://lore.kernel.org/netdev/CAHS8izPm6XRS54LdCDZVd0C75tA1zHSu6jLVO8nzTLX… ================== * TL;DR: Device memory TCP (devmem TCP) is a proposal for transferring data to and/or from device memory efficiently, without bouncing the data to a host memory buffer. * Problem: A large amount of data transfers have device memory as the source and/or destination. Accelerators drastically increased the volume of such transfers. Some examples include: - ML accelerators transferring large amounts of training data from storage into GPU/TPU memory. In some cases ML training setup time can be as long as 50% of TPU compute time, improving data transfer throughput & efficiency can help improving GPU/TPU utilization. - Distributed training, where ML accelerators, such as GPUs on different hosts, exchange data among them. - Distributed raw block storage applications transfer large amounts of data with remote SSDs, much of this data does not require host processing. Today, the majority of the Device-to-Device data transfers the network are implemented as the following low level operations: Device-to-Host copy, Host-to-Host network transfer, and Host-to-Device copy. The implementation is suboptimal, especially for bulk data transfers, and can put significant strains on system resources, such as host memory bandwidth, PCIe bandwidth, etc. One important reason behind the current state is the kernel’s lack of semantics to express device to network transfers. * Proposal: In this patch series we attempt to optimize this use case by implementing socket APIs that enable the user to: 1. send device memory across the network directly, and 2. receive incoming network packets directly into device memory. Packet _payloads_ go directly from the NIC to device memory for receive and from device memory to NIC for transmit. Packet _headers_ go to/from host memory and are processed by the TCP/IP stack normally. The NIC _must_ support header split to achieve this. Advantages: - Alleviate host memory bandwidth pressure, compared to existing network-transfer + device-copy semantics. - Alleviate PCIe BW pressure, by limiting data transfer to the lowest level of the PCIe tree, compared to traditional path which sends data through the root complex. * Patch overview: ** Part 1: netlink API Gives user ability to bind dma-buf to an RX queue. ** Part 2: scatterlist support Currently the standard for device memory sharing is DMABUF, which doesn't generate struct pages. On the other hand, networking stack (skbs, drivers, and page pool) operate on pages. We have 2 options: 1. Generate struct pages for dmabuf device memory, or, 2. Modify the networking stack to process scatterlist. Approach #1 was attempted in RFC v1. RFC v2 implements approach #2. ** part 3: page pool support We piggy back on page pool memory providers proposal: https://github.com/kuba-moo/linux/tree/pp-providers It allows the page pool to define a memory provider that provides the page allocation and freeing. It helps abstract most of the device memory TCP changes from the driver. ** part 4: support for unreadable skb frags Page pool iovs are not accessible by the host; we implement changes throughput the networking stack to correctly handle skbs with unreadable frags. ** Part 5: recvmsg() APIs We define user APIs for the user to send and receive device memory. Not included with this series is the GVE devmem TCP support, just to simplify the review. Code available here if desired: https://github.com/mina/linux/tree/tcpdevmem This series is built on top of net-next with Jakub's pp-providers changes cherry-picked. * NIC dependencies: 1. (strict) Devmem TCP require the NIC to support header split, i.e. the capability to split incoming packets into a header + payload and to put each into a separate buffer. Devmem TCP works by using device memory for the packet payload, and host memory for the packet headers. 2. (optional) Devmem TCP works better with flow steering support & RSS support, i.e. the NIC's ability to steer flows into certain rx queues. This allows the sysadmin to enable devmem TCP on a subset of the rx queues, and steer devmem TCP traffic onto these queues and non devmem TCP elsewhere. The NIC I have access to with these properties is the GVE with DQO support running in Google Cloud, but any NIC that supports these features would suffice. I may be able to help reviewers bring up devmem TCP on their NICs. * Testing: The series includes a udmabuf kselftest that show a simple use case of devmem TCP and validates the entire data path end to end without a dependency on a specific dmabuf provider. ** Test Setup Kernel: net-next with this series and memory provider API cherry-picked locally. Hardware: Google Cloud A3 VMs. NIC: GVE with header split & RSS & flow steering support.

[PATCH net-next v3] selftests: drv-net: add checksum tests

by Willem de Bruijn

From: Willem de Bruijn <willemb(a)google.com> Run tools/testing/selftest/net/csum.c as part of drv-net. This binary covers multiple scenarios, based on arguments given, for both IPv4 and IPv6: - Accept UDP correct checksum - Detect UDP invalid checksum - Accept TCP correct checksum - Detect TCP invalid checksum - Transmit UDP: basic checksum offload - Transmit UDP: zero checksum conversion The test direction is reversed between receive and transmit tests, so that the NIC under test is always the local machine. In total this adds up to 12 testcases, with more to follow. For conciseness, I replaced individual functions with a function factory. Also detect hardware offload feature availability using Ethtool netlink and skip tests when either feature is off. This need may be common for offload feature tests and eventually deserving of a thin wrapper in lib.py. Missing are the PF_PACKET based send tests ('-P'). These use virtio_net_hdr to program hardware checksum offload. Which requires looking up the local MAC address and (harder) the MAC of the next hop. I'll have to give it some though how to do that robustly and where that code would belong.

When building with clang, via: make LLVM=1 -C tools/testing/selftests ...two types of warnings occur: warning: absolute value function 'abs' given an argument of type 'long' but has parameter of type 'int' which may cause truncation of value warning: taking the absolute value of unsigned type 'unsigned long' has no effect Fix these by: a) using labs() in place of abs(), when long integers are involved, and b) Change to use signed integer data types, in places where subtraction is used (and could end up with negative values). c) Remove a duplicate abs() call in cmt_test.c.

[PATCH] selftests/netfilter: formally SKIP() two cases of setup failure

by John Hubbard

If mnl_socket_open() or mnl_socket_bind() fails, it's generally due to not having the user space parts fully installed and configured correctly. This was previously ignored and reported as a test PASS, but what really happened is that the tests were being skipped. This led to generating inaccurate TAP output (I've omitted the leading '#' character): Totals: pass:3 fail:0 xfail:0 xpass:0 skip:0 error:0 Fix this by using kselftest's SKIP() macro. The new output on the same misconfigured system shows: Totals: pass:0 fail:0 xfail:0 xpass:0 skip:3 error:0 This was briefly discussed already with Felix Huettner [1].

[PATCH AUTOSEL 6.8 18/52] KVM: selftests: Add test for uaccesses to non-existent vgic-v2 CPUIF

by Sasha Levin

From: Oliver Upton <oliver.upton(a)linux.dev> [ Upstream commit 160933e330f4c5a13931d725a4d952a4b9aefa71 ] Assert that accesses to a non-existent vgic-v2 CPU interface consistently fail across the various KVM device attr ioctls. This also serves as a regression test for a bug wherein KVM hits a NULL dereference when the CPUID specified in the ioctl is invalid. Note that there is no need to print the observed errno, as TEST_ASSERT() will take care of it.

[PATCH v2] selftests/resctrl: fix clang build warnings related to abs(), labs() calls

by John Hubbard

First of all, in order to build with clang at all, one must first apply Valentin Obst's build fix for LLVM [1]. Furthermore, for this particular resctrl directory, my pending fix [2] must also be applied. Once those fixes are in place, then when building with clang, via: make LLVM=1 -C tools/testing/selftests ...two types of warnings occur: warning: absolute value function 'abs' given an argument of type 'long' but has parameter of type 'int' which may cause truncation of value warning: taking the absolute value of unsigned type 'unsigned long' has no effect Fix these by: a) using labs() in place of abs(), when long integers are involved, and b) Change to use signed integer data types, in places where subtraction is used (and could end up with negative values). [1] https://lore.kernel.org/all/20240329-selftests-libmk-llvm-rfc-v1-1-2f9ed7d1… [2] https://lore.kernel.org/all/20240503021712.78601-1-jhubbard@nvidia.com/ Cc: Reinette Chatre <reinette.chatre(a)intel.com> Signed-off-by: John Hubbard <jhubbard(a)nvidia.com> --- Hi Reinette, This v2 includes a fix for the bugs that you pointed out (thanks!) in v1.

[PATCH net-next v3] selftest: epoll_busy_poll: epoll busy poll tests

by Joe Damato

Add a simple test for the epoll busy poll ioctls, using the kernel selftest harness. This test ensures that the ioctls have the expected return codes and that the kernel properly gets and sets epoll busy poll parameters. The test can be expanded in the future to do real busy polling (provided another machine to act as the client is available). Signed-off-by: Joe Damato <jdamato(a)fastly.com> --- v2 -> v3: - Added this changelog :) - Add libcap to LDLIBS. - Most other changes are in test_set_invalid: - Check if CAP_NET_ADMIN is set in the effective set before setting busy_poll_budget over NAPI_POLL_WEIGHT. The test which follows assumes CAP_NET_ADMIN. - Drop CAP_NET_ADMIN from effective set in order to ensure the ioctl fails when busy_poll_budget exceeds NAPI_POLL_WEIGHT. - Put CAP_NET_ADMIN back into the effective set afterwards. - Changed self->params.busy_poll_budget from 65535 to UINT16_MAX. - Changed the cast for params.busy_poll_usecs from unsigned int to uint32_t in the test_set_invalid case. v1 -> v2: - Rewrote completely to use kernel self test harness. tools/testing/selftests/net/.gitignore | 1 + tools/testing/selftests/net/Makefile | 3 +- tools/testing/selftests/net/epoll_busy_poll.c | 320 ++++++++++++++++++ 3 files changed, 323 insertions(+), 1 deletion(-) create mode 100644 tools/testing/selftests/net/epoll_busy_poll.c diff --git a/tools/testing/selftests/net/.gitignore b/tools/testing/selftests/net/.gitignore index d996a0ab0765..777cfd027076 100644 --- a/tools/testing/selftests/net/.gitignore +++ b/tools/testing/selftests/net/.gitignore @@ -5,6 +5,7 @@ bind_wildcard csum cmsg_sender diag_uid +epoll_busy_poll fin_ack_lat gro hwtstamp_config diff --git a/tools/testing/selftests/net/Makefile b/tools/testing/selftests/net/Makefile index 5befca249452..c6112d08b233 100644 --- a/tools/testing/selftests/net/Makefile +++ b/tools/testing/selftests/net/Makefile @@ -67,7 +67,7 @@ TEST_GEN_FILES += ipsec TEST_GEN_FILES += ioam6_parser TEST_GEN_FILES += gro TEST_GEN_PROGS = reuseport_bpf reuseport_bpf_cpu reuseport_bpf_numa -TEST_GEN_PROGS += reuseport_dualstack reuseaddr_conflict tls tun tap +TEST_GEN_PROGS += reuseport_dualstack reuseaddr_conflict tls tun tap epoll_busy_poll TEST_GEN_FILES += toeplitz TEST_GEN_FILES += cmsg_sender TEST_GEN_FILES += stress_reuseport_listen @@ -102,6 +102,7 @@ TEST_INCLUDES := forwarding/lib.sh include ../lib.mk +$(OUTPUT)/epoll_busy_poll: LDLIBS += -lcap $(OUTPUT)/reuseport_bpf_numa: LDLIBS += -lnuma $(OUTPUT)/tcp_mmap: LDLIBS += -lpthread -lcrypto $(OUTPUT)/tcp_inq: LDLIBS += -lpthread diff --git a/tools/testing/selftests/net/epoll_busy_poll.c b/tools/testing/selftests/net/epoll_busy_poll.c new file mode 100644 index 000000000000..9dd2830fd67c --- /dev/null +++ b/tools/testing/selftests/net/epoll_busy_poll.c @@ -0,0 +1,320 @@ +// SPDX-License-Identifier: GPL-2.0-or-later + +/* Basic per-epoll context busy poll test. + * + * Only tests the ioctls, but should be expanded to test two connected hosts in + * the future + */ + +#define _GNU_SOURCE + +#include <error.h> +#include <errno.h> +#include <inttypes.h> +#include <limits.h> +#include <stdio.h> +#include <stdlib.h> +#include <string.h> +#include <unistd.h> + +#include <sys/capability.h> + +#include <sys/epoll.h> +#include <sys/ioctl.h> +#include <sys/socket.h> + +#include "../kselftest_harness.h" + +/* if the headers haven't been updated, we need to define some things */ +#if !defined(EPOLL_IOC_TYPE) +struct epoll_params { + uint32_t busy_poll_usecs;

[PATCH bpf-next] bpf, arm64: Add support for lse atomics in bpf_arena

by Puranjay Mohan

When LSE atomics are available, BPF atomic instructions are implemented as single ARM64 atomic instructions, therefore it is easy to enable these in bpf_arena using the currently available exception handling setup. LL_SC atomics use loops and therefore would need more work to enable in bpf_arena. Enable LSE atomics based instructions in bpf_arena and use the bpf_jit_supports_insn() callback to reject atomics in bpf_arena if LSE atomics are not available. All atomics and arena_atomics selftests are passing: [root@ip-172-31-2-216 bpf]# ./test_progs -a atomics,arena_atomics #3/1 arena_atomics/add:OK #3/2 arena_atomics/sub:OK #3/3 arena_atomics/and:OK #3/4 arena_atomics/or:OK #3/5 arena_atomics/xor:OK #3/6 arena_atomics/cmpxchg:OK #3/7 arena_atomics/xchg:OK #3 arena_atomics:OK #10/1 atomics/add:OK #10/2 atomics/sub:OK #10/3 atomics/and:OK #10/4 atomics/or:OK #10/5 atomics/xor:OK #10/6 atomics/cmpxchg:OK #10/7 atomics/xchg:OK #10 atomics:OK Summary: 2/14 PASSED, 0 SKIPPED, 0 FAILED Signed-off-by: Puranjay Mohan <puranjay(a)kernel.org> --- arch/arm64/net/bpf_jit_comp.c | 48 ++++++++++++++++---- tools/testing/selftests/bpf/DENYLIST.aarch64 | 1 - 2 files changed, 40 insertions(+), 9 deletions(-) diff --git a/arch/arm64/net/bpf_jit_comp.c b/arch/arm64/net/bpf_jit_comp.c index 76b91f36c729..53347d4217f4 100644 --- a/arch/arm64/net/bpf_jit_comp.c +++ b/arch/arm64/net/bpf_jit_comp.c @@ -494,20 +494,26 @@ static int emit_bpf_tail_call(struct jit_ctx *ctx) static int emit_lse_atomic(const struct bpf_insn *insn, struct jit_ctx *ctx) { const u8 code = insn->code; + const u8 arena_vm_base = bpf2a64[ARENA_VM_START]; const u8 dst = bpf2a64[insn->dst_reg]; const u8 src = bpf2a64[insn->src_reg]; const u8 tmp = bpf2a64[TMP_REG_1]; const u8 tmp2 = bpf2a64[TMP_REG_2]; const bool isdw = BPF_SIZE(code) == BPF_DW; + const bool arena = BPF_MODE(code) == BPF_PROBE_ATOMIC; const s16 off = insn->off; - u8 reg; + u8 reg = dst; - if (!off) { - reg = dst; - } else { - emit_a64_mov_i(1, tmp, off, ctx); - emit(A64_ADD(1, tmp, tmp, dst), ctx); - reg = tmp; + if (off || arena) { + if (off) { + emit_a64_mov_i(1, tmp, off, ctx); + emit(A64_ADD(1, tmp, tmp, dst), ctx); + reg = tmp; + } + if (arena) { + emit(A64_ADD(1, tmp, reg, arena_vm_base), ctx); + reg = tmp; + } } switch (insn->imm) { @@ -576,6 +582,12 @@ static int emit_ll_sc_atomic(const struct bpf_insn *insn, struct jit_ctx *ctx) u8 reg; s32 jmp_offset; + if (BPF_MODE(code) == BPF_PROBE_ATOMIC) { + /* ll_sc based atomics don't support unsafe pointers yet. */ + pr_err_once("unknown atomic opcode %02x\n", code); + return -EINVAL; + } + if (!off) { reg = dst; } else { @@ -777,7 +789,8 @@ static int add_exception_handler(const struct bpf_insn *insn, if (BPF_MODE(insn->code) != BPF_PROBE_MEM && BPF_MODE(insn->code) != BPF_PROBE_MEMSX && - BPF_MODE(insn->code) != BPF_PROBE_MEM32) + BPF_MODE(insn->code) != BPF_PROBE_MEM32 && + BPF_MODE(insn->code) != BPF_PROBE_ATOMIC) return 0; if (!ctx->prog->aux->extable || @@ -1474,12 +1487,18 @@ static int build_insn(const struct bpf_insn *insn, struct jit_ctx *ctx, case BPF_STX | BPF_ATOMIC | BPF_W: case BPF_STX | BPF_ATOMIC | BPF_DW: + case BPF_STX | BPF_PROBE_ATOMIC | BPF_W: + case BPF_STX | BPF_PROBE_ATOMIC | BPF_DW: if (cpus_have_cap(ARM64_HAS_LSE_ATOMICS)) ret = emit_lse_atomic(insn, ctx); else ret = emit_ll_sc_atomic(insn, ctx); if (ret) return ret; + + ret = add_exception_handler(insn, ctx, dst); + if (ret) + return ret; break; default: @@ -2527,6 +2546,19 @@ bool bpf_jit_supports_arena(void) return true; } +bool bpf_jit_supports_insn(struct bpf_insn *insn, bool in_arena) +{ + if (!in_arena) + return true; + switch (insn->code) { + case BPF_STX | BPF_ATOMIC | BPF_W: + case BPF_STX | BPF_ATOMIC | BPF_DW: + if (!cpus_have_cap(ARM64_HAS_LSE_ATOMICS)) + return false; + } + return true; +} + void bpf_jit_free(struct bpf_prog *prog) { if (prog->jited) { diff --git a/tools/testing/selftests/bpf/DENYLIST.aarch64 b/tools/testing/selftests/bpf/DENYLIST.aarch64 index cf657fc35619..0445ac38bc07 100644 --- a/tools/testing/selftests/bpf/DENYLIST.aarch64 +++ b/tools/testing/selftests/bpf/DENYLIST.aarch64 @@ -10,4 +10,3 @@ fill_link_info/kprobe_multi_link_info # bpf_program__attach_kprobe_mu fill_link_info/kretprobe_multi_link_info # bpf_program__attach_kprobe_multi_opts unexpected error: -95 fill_link_info/kprobe_multi_invalid_ubuff # bpf_program__attach_kprobe_multi_opts unexpected error: -95 missed/kprobe_recursion # missed_kprobe_recursion__attach unexpected error: -95 (errno 95) -arena_atomics -- 2.40.1

[PATCH v5 8/8] selftests/pcie_bwctrl: Create selftests

by Ilpo Järvinen

Create selftests for PCIe BW control through the PCIe cooling device sysfs interface. First, the BW control selftest finds the PCIe Port to test with. By default, the PCIe Port with the highest Link Speed is selected but another PCIe Port can be provided with -d parameter. The actual test steps the cur_state of the cooling device one-by-one from max_state to what the cur_state was initially. The speed change is confirmed by observing the current_link_speed for the corresponding PCIe Port.

[PATCH v2] selftests/net: fix uninitialized variables

by John Hubbard

When building with clang, via: make LLVM=1 -C tools/testing/selftest ...clang warns about three variables that are not initialized in all cases: 1) The opt_ipproto_off variable is used uninitialized if "testname" is not "ip". Willem de Bruijn pointed out that this is an actual bug, and suggested the fix that I'm using here (thanks!). 2) The addr_len is used uninitialized, but only in the assert case, which bails out, so this is harmless. 3) The family variable in add_listener() is only used uninitialized in the error case (neither IPv4 nor IPv6 is specified), so it's also harmless. Fix by initializing each variable.

[PATCH AUTOSEL 6.6 15/43] KVM: selftests: Add test for uaccesses to non-existent vgic-v2 CPUIF

by Sasha Levin

From: Oliver Upton <oliver.upton(a)linux.dev> [ Upstream commit 160933e330f4c5a13931d725a4d952a4b9aefa71 ] Assert that accesses to a non-existent vgic-v2 CPU interface consistently fail across the various KVM device attr ioctls. This also serves as a regression test for a bug wherein KVM hits a NULL dereference when the CPUID specified in the ioctl is invalid. Note that there is no need to print the observed errno, as TEST_ASSERT() will take care of it.

[BUG selftests/pidfd] pidfd_setns_test HANG

Hi, all, With the latest 6.9-rc7 torvalds tree kernel, the "make kselftest" always hangs in the following ./pidfd_setns_test. Symptoms are that all ./pidfd_netne_test processes end up in pause() syscalls, with nothing to wake them up. Please find the config attached. All the options from the selftests/pidfdconfig are on (verified): CONFIG_UTS_NS=y CONFIG_IPC_NS=y CONFIG_USER_NS=y CONFIG_PID_NS=y CONFIG_NET_NS=y CONFIG_CGROUPS=y CONFIG_CHECKPOINT_RESTORE=y root 2090101 5211 0 21:53 pts/1 00:00:00 make OUTPUT=/home/marvin/linux/kernel/linux_torvalds/tools/testing/selftests/pidfd -C pidfd run_tests SRC_PATH=/home/marvin/linux/kernel/linux_torvalds/tools/testing/selftests OB root 2090102 2090101 0 21:53 pts/1 00:00:00 /bin/sh -c BASE_DIR="/home/marvin/linux/kernel/linux_torvalds/tools/testing/selftests"; . /home/marvin/linux/kernel/linux_torvalds/tools/testing/selftests/kselftest/runner.sh; if root 2133026 2090102 0 21:54 pts/1 00:00:00 /bin/sh -c BASE_DIR="/home/marvin/linux/kernel/linux_torvalds/tools/testing/selftests"; . /home/marvin/linux/kernel/linux_torvalds/tools/testing/selftests/kselftest/runner.sh; if root 2133027 2133026 0 21:54 pts/1 00:00:00 /bin/sh -c BASE_DIR="/home/marvin/linux/kernel/linux_torvalds/tools/testing/selftests"; . /home/marvin/linux/kernel/linux_torvalds/tools/testing/selftests/kselftest/runner.sh; if root 2133028 2133027 0 21:54 pts/1 00:00:00 /bin/sh -c BASE_DIR="/home/marvin/linux/kernel/linux_torvalds/tools/testing/selftests"; . /home/marvin/linux/kernel/linux_torvalds/tools/testing/selftests/kselftest/runner.sh; if root 2133031 2133028 0 21:54 pts/1 00:00:00 /bin/sh -c BASE_DIR="/home/marvin/linux/kernel/linux_torvalds/tools/testing/selftests"; . /home/marvin/linux/kernel/linux_torvalds/tools/testing/selftests/kselftest/runner.sh; if root 2133033 2133031 0 21:54 pts/1 00:00:00 perl /home/marvin/linux/kernel/linux_torvalds/tools/testing/selftests/kselftest/prefix.pl root 2133050 2887 0 21:54 pts/1 00:00:00 ./pidfd_setns_test root 2133051 2887 0 21:54 pts/1 00:00:00 ./pidfd_setns_test root 2133056 2887 0 21:54 pts/1 00:00:00 ./pidfd_setns_test root 2133057 2887 0 21:54 pts/1 00:00:00 ./pidfd_setns_test root 2133062 2887 0 21:54 pts/1 00:00:00 ./pidfd_setns_test root 2133063 2887 0 21:54 pts/1 00:00:00 ./pidfd_setns_test root 2133068 2887 0 21:54 pts/1 00:00:00 ./pidfd_setns_test root 2133069 2887 0 21:54 pts/1 00:00:00 ./pidfd_setns_test . . . marvin@defiant:~/linux/kernel/linux_torvalds$ sudo bash [sudo] password for marvin: root@defiant:/home/marvin/linux/kernel/linux_torvalds# strace -p 2133050 strace: Process 2133050 attached pause(^Cstrace: Process 2133050 detached <detached ...> root@defiant:/home/marvin/linux/kernel/linux_torvalds# strace -p 2133051 strace: Process 2133051 attached pause(^Cstrace: Process 2133051 detached <detached ...> root@defiant:/home/marvin/linux/kernel/linux_torvalds# strace -p 2133056 strace: Process 2133056 attached pause(^Cstrace: Process 2133056 detached <detached ...> root@defiant:/home/marvin/linux/kernel/linux_torvalds# strace -p 2133057 strace: Process 2133057 attached pause(^Cstrace: Process 2133057 detached <detached ...> root@defiant:/home/marvin/linux/kernel/linux_torvalds# strace -p 2133062 strace: Process 2133062 attached pause(^Cstrace: Process 2133062 detached <detached ...> root@defiant:/home/marvin/linux/kernel/linux_torvalds# strace -p 2133063 strace: Process 2133063 attached pause(^Cstrace: Process 2133063 detached <detached ...> root@defiant:/home/marvin/linux/kernel/linux_torvalds# root@defiant:/home/marvin/linux/kernel/linux_torvalds# root@defiant:/home/marvin/linux/kernel/linux_torvalds# strace -p 2133068 strace: Process 2133068 attached pause(^Cstrace: Process 2133068 detached <detached ...> root@defiant:/home/marvin/linux/kernel/linux_torvalds# strace -p 2133069 strace: Process 2133069 attached pause(^Cstrace: Process 2133069 detached <detached ...> root@defiant:/home/marvin/linux/kernel/linux_torvalds# The output log is: #

[PATCH net-next v8 0/3] net: gro: remove network_header use, move p->{flush/flush_id} calculations to L4

by Richard Gobert

The cb fields network_offset and inner_network_offset are used instead of skb->network_header throughout GRO. These fields are 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. These fields are checked in L4 instead. 3rd patch adds tests for different flush_id flows in GRO. v7 -> v8: - Remove network_header use in gro - Re-send commits after the dependent patch to net was applied - v7: https://lore.kernel.org/all/20240412155533.115507-1-richardbgobert@gmail.co… v6 -> v7: - Moved bug fixes to a separate submission in net - Added UDP fwd benchmark - v6: https://lore.kernel.org/all/20240410153423.107381-1-richardbgobert@gmail.co… v5 -> v6: - Write inner_network_offset in vxlan and geneve - Ignore is_atomic when DF=0 - v5: https://lore.kernel.org/all/20240408141720.98832-1-richardbgobert@gmail.com/ v4 -> v5: - Add 1st commit - flush id checks in udp_gro_receive segment which can be backported by itself - Add TCP measurements for the 5th commit - Add flush id tests to ensure flush id logic is preserved in GRO - Simplify gro_inet_flush by removing a branch - v4: https://lore.kernel.org/all/202420325182543.87683-1-richardbgobert@gmail.co… v3 -> v4: - Fix code comment and commit message typos - v3: https://lore.kernel.org/all/f939c84a-2322-4393-a5b0-9b1e0be8ed8e@gmail.com/ v2 -> v3: - Use napi_gro_cb instead of skb->{offset} - v2: https://lore.kernel.org/all/2ce1600b-e733-448b-91ac-9d0ae2b866a4@gmail.com/ 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 (3): net: gro: use cb instead of skb->network_header net: gro: move L3 flush checks to tcp_gro_receive and udp_gro_receive_segment selftests/net: add flush id selftests include/net/gro.h | 75 +++++++++++++-- net/core/gro.c | 3 - net/ipv4/af_inet.c | 45 +-------- net/ipv4/tcp_offload.c | 18 +--- net/ipv4/udp_offload.c | 10 +- net/ipv6/ip6_offload.c | 16 +--- net/ipv6/tcpv6_offload.c | 3 +- tools/testing/selftests/net/gro.c | 147 ++++++++++++++++++++++++++++++ 8 files changed, 225 insertions(+), 92 deletions(-) -- 2.36.1

[PATCH v6 00/10] Fix Kselftest's vfork() side effects

by Mickaël Salaün

Hi, This sixth series just update the last patch description. Shuah, I think this should be in -next really soon to make sure everything works fine for the v6.9 release, which is not currently the case. I cannot test against all kselftests though. I would prefer to let you handle this, but I guess you're not able to do so and I'll push it on my branch without reply from you. Even if I push it on my branch, please push it on yours too as soon as you see this and I'll remove it from mine. Mark, Jakub, could you please test this series? As reported by Kernel Test Robot [1] and Sean Christopherson [2], some tests fail since v6.9-rc1 . This is due to the use of vfork() which introduced some side effects. Similarly, while making it more generic, a previous commit made some Landlock file system tests flaky, and subject to the host's file system mount configuration. This series fixes all these side effects by replacing vfork() with clone3() and CLONE_VFORK, which is cleaner (no arbitrary shared memory) and makes the Kselftest framework more robust. I tried different approaches and I found this one to be the cleaner and less invasive for current test cases. I successfully ran the following tests (using TEST_F and fork/clone/clone3, and KVM_ONE_VCPU_TEST) with this series: - kvm:fix_hypercall_test - kvm:sync_regs_test - kvm:userspace_msr_exit_test - kvm:vmx_pmu_caps_test - landlock:fs_test - landlock:net_test - landlock:ptrace_test - move_mount_set_group:move_mount_set_group_test - net/af_unix:scm_pidfd - perf_events:remove_on_exec - pidfd:pidfd_getfd_test - pidfd:pidfd_setns_test - seccomp:seccomp_bpf - user_events:abi_test [1] https://lore.kernel.org/oe-lkp/202403291015.1fcfa957-oliver.sang@intel.com [2] https://lore.kernel.org/r/ZjPelW6-AbtYvslu@google.com Previous versions: v1: https://lore.kernel.org/r/20240426172252.1862930-1-mic@digikod.net v2: https://lore.kernel.org/r/20240429130931.2394118-1-mic@digikod.net v3: https://lore.kernel.org/r/20240429191911.2552580-1-mic@digikod.net v4: https://lore.kernel.org/r/20240502210926.145539-1-mic@digikod.net v5: https://lore.kernel.org/r/20240503105820.300927-1-mic@digikod.net Regards, Mickaël Salaün (10): selftests/pidfd: Fix config for pidfd_setns_test selftests/landlock: Fix FS tests when run on a private mount point selftests/harness: Fix fixture teardown selftests/harness: Fix interleaved scheduling leading to race conditions selftests/landlock: Do not allocate memory in fixture data selftests/harness: Constify fixture variants selftests/pidfd: Fix wrong expectation selftests/harness: Share _metadata between forked processes selftests/harness: Fix vfork() side effects selftests/harness: Handle TEST_F()'s explicit exit codes tools/testing/selftests/kselftest_harness.h | 122 +++++++++++++----- tools/testing/selftests/landlock/fs_test.c | 83 +++++++----- tools/testing/selftests/pidfd/config | 2 + .../selftests/pidfd/pidfd_setns_test.c | 2 +- 4 files changed, 143 insertions(+), 66 deletions(-) base-commit: e67572cd2204894179d89bd7b984072f19313b03 -- 2.45.0
