[PATCH v3 1/3] selftests: net: .gitignore the scratch directory of bpf

by Andrei Gherzan

The net/bpf Makefile uses a similar build infrastructure to BPF[1] while building libbpf as a dependency of nat6to4. This change adds a .gitignore entry for SCRATCH_DIR where libbpf and its headers end up built/installed.

[PATCH v2 1/2] selftests: net: Fix missing nat6to4.o when running udpgro_frglist.sh

by Andrei Gherzan

The udpgro_frglist.sh uses nat6to4.o which is tested for existence in bpf/nat6to4.o (relative to the script). This is where the object is compiled. Even so, the script attempts to use it as part of tc with a different path (../bpf/nat6to4.o). As a consequence, this fails the script: Error opening object ../bpf/nat6to4.o: No such file or directory Cannot initialize ELF context! Unable to load program This change refactors these references to use a variable for consistency and also reformats two long lines.

[RFC PATCH v2] kunit: Add "hooks" to call into KUnit when it's built as a module

by David Gow

KUnit has several macros and functions intended for use from non-test code. These hooks, currently the kunit_get_current_test() and kunit_fail_current_test() macros, didn't work when CONFIG_KUNIT=m. In order to support this case, the required functions and static data need to be available unconditionally, even when KUnit itself is not built-in. The new 'hooks.c' file is therefore always included, and has both the static key required for kunit_get_current_test(), and a function pointer to the real implementation of __kunit_fail_current_test(), which is populated when the KUnit module is loaded. A new header, kunit/hooks-table.h, contains a table of all hooks, and is repeatedly included with different definitions of the KUNIT_HOOK() in order to automatically generate the needed function pointer tables. When KUnit is disabled, or the module is not loaded, these function pointers are all NULL. This shouldn't be a problem, as they're all used behind wrappers which check kunit_running and/or that the pointer is non-NULL. This can then be extended for future features which require similar "hook" behaviour, such as static stubs: https://lore.kernel.org/all/20221208061841.2186447-1-davidgow@google.com/ Signed-off-by: David Gow <davidgow(a)google.com> --- This is basically a prerequisite for the stub features working when KUnit is built as a module, and should nicely make a few other tests work then, too. v2 adds a slightly-excessive macro-based system for defining hooks. This made adding the static stub hooks absolutely trivial, and the complexity is totally hidden from the user (being an internal KUnit implementation detail), so I'm more comfortable with this than some other macro magic. It does however result in a huge number of checkpatch.pl errors, as we're using macros in unconventional ways, and checkpatch just can't work out the syntax. These are mostly "Macros with complex values should be enclosed in parentheses", "Macros with multiple statements should be enclosed in a do - while loop", and similar, which don't apply due to the macros not being expressions: they are mostly declarations or assignment statements. There are a few others where checkpatch thinks that the return value is the function name and similar, so complains about the style. Open questions: - Is this macro-based system worth it, or was v1 better? - Should we rename test-bug.h to hooks.h or similar. (I think so, but would rather do it in a separate patch, to make it easier to review. There are a few includes of it scattered about.) - Is making these NULL when KUnit isn't around sensible, or should we auto-generate a "default" implementation. This is a pretty easy extension to the macros here. (I think NULL is good for now, as we have wrappers for these anyway. If we want to change our minds later as we add more hooks, it's easy.) - Any other thoughts? Cheers, -- David Changes since RFC v1: https://lore.kernel.org/all/20230117142737.246446-1-davidgow@google.com/ - Major refit to auto-generate the hook code using macros. - (Note that previous Reviewed-by tags have not been added, as this is a big enough change it probably needs a re-reviews.

[PATCH v3] lib/hashtable_test.c: add test for the hashtable structure

by Rae Moar

Add a KUnit test for the kernel hashtable implementation in include/linux/hashtable.h. Note that this version does not yet test each of the rcu alternative versions of functions. Signed-off-by: Rae Moar <rmoar(a)google.com> Reviewed-by: David Gow <davidgow(a)google.com> --- Changes since v2: - Remove extraneous hash_init() calls when using DEFINE_HASHTABLE. - Change up the size of the hashtables in different tests. - Change formatting to group lines regarding the same hashtable_test_entry. - Use KUNIT_ASSERT_LEQ() and KUNIT_ASSERT_GEQ() instead of a few if statements. Changes since v1: - Change Kconfig.debug message to be more succinct. - Directly increment current element's visited field rather than looking up corresponding element. - Use KUNIT_ASSERT_... statements to check the keys are within range rather than using if statements. - Change hash_for_each_possible test to check buckets using a hash_for_each method instead of calculating the bucket number using hash_min. Note: The check patch script is outputting open brace errors on lines 152, 185, 239 of lib/hashtable_test.c. However, I think these errors are a mistake as the format of the braces on those lines is consistent with the Linux Kernel style guide. As David Gow commented on the last version, "This is a known issue with checkpatch and function names with "for_each" in them.

[PATCH] testing: kselftest_harness: add filtering and enumerating tests

by Jakub Kicinski

As the number of test cases and length of execution grows it's useful to select only a subset of tests. In TLS for instance we have a matrix of variants for different crypto protocols and during development mostly care about testing a handful. This is quicker and makes reading output easier. This patch adds argument parsing to kselftest_harness. It supports a couple of ways to filter things, I could not come up with one way which will cover all cases. The first and simplest switch is -r which takes the name of a test to run (can be specified multiple times). For example: $ ./my_test -r some.test.name -r some.other.name will run tests some.test.name and some.other.name (where "some" is the fixture, "test" and "other" and "name is the test.) Then there is a handful of group filtering options. f/v/t for filtering by fixture/variant/test. They have both positive (match -> run) and negative versions (match -> skip). If user specifies any positive option we assume the default is not to run the tests. If only negative options are set we assume the tests are supposed to be run by default. Usage: ./tools/testing/selftests/net/tls [-h|-l] [-t|-T|-v|-V|-f|-F|-r name] -h print help -l list all tests -t name include test -T name exclude test -v name include variant -V name exclude variant -f name include fixture -F name exclude fixture -r name run specified test Test filter options can be specified multiple times. The filtering stops at the first match. For example to include all tests from variant 'bla' but not test 'foo' specify '-T foo -v bla'. Here we can request for example all tests from fixture "foo" to run: ./my_test -f foo or to skip variants var1 and var2: ./my_test -V var1 -V var2 Signed-off-by: Jakub Kicinski <kuba(a)kernel.org> --- v2: - use getopt() CC: keescook(a)chromium.org CC: luto(a)amacapital.net CC: wad(a)chromium.org CC: shuah(a)kernel.org CC: linux-kselftest(a)vger.kernel.org --- tools/testing/selftests/kselftest_harness.h | 142 +++++++++++++++++++- 1 file changed, 137 insertions(+), 5 deletions(-) diff --git a/tools/testing/selftests/kselftest_harness.h b/tools/testing/selftests/kselftest_harness.h index 25f4d54067c0..d8bff2005dfc 100644 --- a/tools/testing/selftests/kselftest_harness.h +++ b/tools/testing/selftests/kselftest_harness.h @@ -54,6 +54,7 @@ #define _GNU_SOURCE #endif #include <asm/types.h> +#include <ctype.h> #include <errno.h> #include <stdbool.h> #include <stdint.h> @@ -985,6 +986,127 @@ void __wait_for_test(struct __test_metadata *t) } } +static void test_harness_list_tests(void) +{ + struct __fixture_variant_metadata *v; + struct __fixture_metadata *f; + struct __test_metadata *t; + + for (f = __fixture_list; f; f = f->next) { + v = f->variant; + t = f->tests; + + if (f == __fixture_list) + fprintf(stderr, "%-20s %-25s %s\n", + "# FIXTURE", "VARIANT", "TEST"); + else + fprintf(stderr, "--------------------------------------------------------------------------------\n"); + + do { + fprintf(stderr, "%-20s %-25s %s\n", + t == f->tests ? f->name : "", + v ? v->name : "", + t ? t->name : ""); + + v = v ? v->next : NULL; + t = t ? t->next : NULL; + } while (v || t); + } +} + +static int test_harness_argv_check(int argc, char **argv) +{ + int opt; + + while ((opt = getopt(argc, argv, "hlF:f:V:v:t:T:r:")) != -1) { + switch (opt) { + case 'f': + case 'F': + case 'v': + case 'V': + case 't': + case 'T': + case 'r': + break; + case 'l': + test_harness_list_tests(); + return KSFT_SKIP; + case 'h': + default: + fprintf(stderr, + "Usage: %s [-h|-l] [-t|-T|-v|-V|-f|-F|-r name]\n" + "\t-h print help\n" + "\t-l list all tests\n" + "\n" + "\t-t name include test\n" + "\t-T name exclude test\n" + "\t-v name include variant\n" + "\t-V name exclude variant\n" + "\t-f name include fixture\n" + "\t-F name exclude fixture\n" + "\t-r name run specified test\n" + "\n" + "Test filter options can be specified " + "multiple times.

[RFC PATCH] selftests: Fix: search kernel headers in $(KHDR_INCLUDES)

by Mathieu Desnoyers

Use $(KHDR_INCLUDES) as lookup path for kernel headers. This prevents building against kernel headers from the build environment in scenarios where kernel headers are installed into a specific output directory (O=...). [ Hopefully I did not break too many things with this selftests-wide change. Additional testing would be welcome before merging, especially given that whenever we get this wrong, it appears to fall-back on the build environment system headers, which hides issues. This applies on top of v6.2-rc3. ] Signed-off-by: Mathieu Desnoyers <mathieu.desnoyers(a)efficios.com> Cc: Shuah Khan <shuah(a)kernel.org> Cc: linux-kselftest(a)vger.kernel.org Cc: Ingo Molnar <mingo(a)redhat.com> Cc: <stable(a)vger.kernel.org> [5.18+] --- tools/testing/selftests/arm64/fp/Makefile | 2 +- tools/testing/selftests/arm64/tags/Makefile | 2 +- tools/testing/selftests/bpf/Makefile | 2 +- tools/testing/selftests/clone3/Makefile | 2 +- tools/testing/selftests/core/Makefile | 2 +- tools/testing/selftests/dma/Makefile | 2 +- tools/testing/selftests/drivers/dma-buf/Makefile | 2 +- tools/testing/selftests/drivers/s390x/uvdevice/Makefile | 3 +-- tools/testing/selftests/filesystems/Makefile | 2 +- tools/testing/selftests/filesystems/binderfs/Makefile | 2 +- tools/testing/selftests/filesystems/epoll/Makefile | 2 +- tools/testing/selftests/futex/functional/Makefile | 2 +- tools/testing/selftests/gpio/Makefile | 2 +- tools/testing/selftests/ipc/Makefile | 2 +- tools/testing/selftests/kcmp/Makefile | 2 +- tools/testing/selftests/media_tests/Makefile | 2 +- tools/testing/selftests/membarrier/Makefile | 2 +- tools/testing/selftests/memfd/Makefile | 2 +- tools/testing/selftests/mount_setattr/Makefile | 2 +- tools/testing/selftests/move_mount_set_group/Makefile | 2 +- tools/testing/selftests/net/Makefile | 2 +- tools/testing/selftests/net/bpf/Makefile | 2 +- tools/testing/selftests/net/mptcp/Makefile | 2 +- tools/testing/selftests/net/openvswitch/Makefile | 2 +- tools/testing/selftests/perf_events/Makefile | 2 +- tools/testing/selftests/pid_namespace/Makefile | 2 +- tools/testing/selftests/pidfd/Makefile | 2 +- tools/testing/selftests/powerpc/ptrace/Makefile | 2 +- tools/testing/selftests/powerpc/security/Makefile | 2 +- tools/testing/selftests/powerpc/syscalls/Makefile | 2 +- tools/testing/selftests/powerpc/tm/Makefile | 2 +- tools/testing/selftests/ptp/Makefile | 2 +- tools/testing/selftests/rseq/Makefile | 2 +- tools/testing/selftests/sched/Makefile | 2 +- tools/testing/selftests/seccomp/Makefile | 2 +- tools/testing/selftests/sync/Makefile | 2 +- tools/testing/selftests/user_events/Makefile | 2 +- tools/testing/selftests/vm/Makefile | 2 +- 38 files changed, 38 insertions(+), 39 deletions(-) diff --git a/tools/testing/selftests/arm64/fp/Makefile b/tools/testing/selftests/arm64/fp/Makefile index 36db61358ed5..932ec8792316 100644 --- a/tools/testing/selftests/arm64/fp/Makefile +++ b/tools/testing/selftests/arm64/fp/Makefile @@ -3,7 +3,7 @@ #

[PATCH 0/3] selftests/tracing: Fix some testcases for recent change

by Masami Hiramatsu (Google)

This includes some patches to fix 2 issues on ftrace selftests. - eprobe filter and eprobe syntax test case were introduced but it doesn't check whether the kernel supports eprobe filter. Thus the new test case fails on the kernel which has eprobe but not support eprobe filter. To solve this issue, add a filter description to README file [1/3] and run the filter syntax error test only if the description is found in the README file [2/3]. - Recently objtool adds prefix symbols for the function padding nops, and the probepoint test case fails because this probepoint test case tests whether the kprobe event can probe the target function and the functions next to the target function. But the prefix symbols can not be probed. Thus these prefix symbols must be skipped [3/3]. Thank you, --- Masami Hiramatsu (Google) (3): tracing/eprobe: Fix to add filter on eprobe description in README file selftests/ftrace: Fix eprobe syntax test case to check filter support selftests/ftrace: Fix probepoint testcase to ignore __pfx_* symbols kernel/trace/trace.c | 2 +- .../test.d/dynevent/eprobes_syntax_errors.tc | 4 +++- .../selftests/ftrace/test.d/kprobe/probepoint.tc | 2 +- 3 files changed, 5 insertions(+), 3 deletions(-) -- Masami Hiramatsu (Google) <mhiramat(a)kernel.org>

[PATCH v7 0/4] Implement IOCTL to get and/or the clear info about PTEs

by Muhammad Usama Anjum

*Changes in v7:* - Add uffd wp async - Update the IOCTL to use uffd under the hood instead of soft-dirty flags Stop using the soft-dirty flags for finding which pages have been written to. It is too delicate and wrong as it shows more soft-dirty pages than the actual soft-dirty pages. There is no interest in correcting it [A][B] as this is how the feature was written years ago. It shouldn't be updated to changed behaviour. Peter Xu has suggested using the async version of the UFFD WP [C] as it is based inherently on the PTEs. So in this patch series, I've added a new mode to the UFFD which is asynchronous version of the write protect. When this variant of the UFFD WP is used, the page faults are resolved automatically by the kernel. The pages which have been written-to can be found by reading pagemap file (!PM_UFFD_WP). This feature can be used successfully to find which pages have been written to from the time the pages were write protected. This works just like the soft-dirty flag without showing any extra pages which aren't soft-dirty in reality. [A] https://lore.kernel.org/all/20221220162606.1595355-1-usama.anjum@collabora.… [B] https://lore.kernel.org/all/20221122115007.2787017-1-usama.anjum@collabora.… [C] https://lore.kernel.org/all/Y6Hc2d+7eTKs7AiH@x1n *Changes in v6:* - Updated the interface and made cosmetic changes *Cover Letter in v5:* Hello, This patch series implements IOCTL on the pagemap procfs file to get the information about the page table entries (PTEs). The following operations are supported in this ioctl: - Get the information if the pages are soft-dirty, file mapped, present or swapped. - Clear the soft-dirty PTE bit of the pages. - Get and clear the soft-dirty PTE bit of the pages atomically. Soft-dirty PTE bit of the memory pages can be read by using the pagemap procfs file. The soft-dirty PTE bit for the whole memory range of the process can be cleared by writing to the clear_refs file. There are other methods to mimic this information entirely in userspace with poor performance: - The mprotect syscall and SIGSEGV handler for bookkeeping - The userfaultfd syscall with the handler for bookkeeping Some benchmarks can be seen here[1]. This series adds features that weren't present earlier: - There is no atomic get soft-dirty PTE bit status and clear operation possible. - The soft-dirty PTE bit of only a part of memory cannot be cleared. Historically, soft-dirty PTE bit tracking has been used in the CRIU project. The procfs interface is enough for finding the soft-dirty bit status and clearing the soft-dirty bit of all the pages of a process. We have the use case where we need to track the soft-dirty PTE bit for only specific pages on demand. We need this tracking and clear mechanism of a region of memory while the process is running to emulate the getWriteWatch() syscall of Windows. This syscall is used by games to keep track of dirty pages to process only the dirty pages. The information related to pages if the page is file mapped, present and swapped is required for the CRIU project[2][3]. The addition of the required mask, any mask, excluded mask and return masks are also required for the CRIU project[2]. The IOCTL returns the addresses of the pages which match the specific masks. The page addresses are returned in struct page_region in a compact form. The max_pages is needed to support a use case where user only wants to get a specific number of pages. So there is no need to find all the pages of interest in the range when max_pages is specified. The IOCTL returns when the maximum number of the pages are found. The max_pages is optional. If max_pages is specified, it must be equal or greater than the vec_size. This restriction is needed to handle worse case when one page_region only contains info of one page and it cannot be compacted. This is needed to emulate the Windows getWriteWatch() syscall. Some non-dirty pages get marked as dirty because of the kernel's internal activity (such as VMA merging as soft-dirty bit difference isn't considered while deciding to merge VMAs). The dirty bit of the pages is stored in the VMA flags and in the per page flags. If any of these two bits are set, the page is considered to be soft dirty. Suppose you have cleared the soft dirty bit of half of VMA which will be done by splitting the VMA and clearing soft dirty bit flag in the half VMA and the pages in it. Now kernel may decide to merge the VMAs again. So the half VMA becomes dirty again. This splitting/merging costs performance. The application receives a lot of pages which aren't dirty in reality but marked as dirty. Performance is lost again here. Also sometimes user doesn't want the newly allocated memory to be marked as dirty. PAGEMAP_NO_REUSED_REGIONS flag solves both the problems. It is used to not depend on the soft dirty flag in the VMA flags. So VMA splitting and merging doesn't happen. It only depends on the soft dirty bit of the individual pages. Thus by using this flag, there may be a scenerio such that the new memory regions which are just created, doesn't look dirty when seen with the IOCTL, but look dirty when seen from procfs. This seems okay as the user of this flag know the implication of using it.

[PATCH net-next 0/8] mptcp: add mixed v4/v6 support for the in-kernel PM

by Matthieu Baerts

Before these patches, the in-kernel Path-Manager would not allow, for the same MPTCP connection, having a mix of subflows in v4 and v6. MPTCP's RFC 8684 doesn't forbid that and it is even recommended to do so as the path in v4 and v6 are likely different. Some networks are also v4 or v6 only, we cannot assume they all have both v4 and v6 support. Patch 1 then removes this artificial constraint in the in-kernel PM currently enforcing there are no mixed subflows in place, either in address announcement or in subflow creation areas. Patch 2 makes sure the sk_ipv6only attribute is also propagated to subflows, just in case a new PM wouldn't respect it. Some selftests have also been added for the in-kernel PM (patch 3). Patches 4 to 8 are just some cleanups and small improvements in the printed messages in the userspace PM. It is not linked to the rest but identified when working on a related patch modifying this selftest, already in -net: commit 4656d72c1efa ("selftests: mptcp: userspace: validate v4-v6 subflows mix") --- Matthieu Baerts (6): mptcp: propagate sk_ipv6only to subflows mptcp: userspace pm: use a single point of exit selftests: mptcp: userspace: print titles selftests: mptcp: userspace: refactor asserts selftests: mptcp: userspace: print error details if any selftests: mptcp: userspace: avoid read errors Paolo Abeni (2): mptcp: let the in-kernel PM use mixed IPv4 and IPv6 addresses selftests: mptcp: add test-cases for mixed v4/v6 subflows net/mptcp/pm_netlink.c | 58 ++++---- net/mptcp/pm_userspace.c | 5 +- net/mptcp/sockopt.c | 1 + tools/testing/selftests/net/mptcp/mptcp_join.sh | 53 ++++++-- tools/testing/selftests/net/mptcp/userspace_pm.sh | 153 +++++++++++++--------- 5 files changed, 171 insertions(+), 99 deletions(-) --- base-commit: 4373a023e0388fc19e27d37f61401bce6ff4c9d7 change-id: 20230123-upstream-net-next-pm-v4-v6-b186481a4b00 Best regards, -- Matthieu Baerts <matthieu.baerts(a)tessares.net>

[PATCH 1/2] selftests: net: Fix missing nat6to4.o when running udpgro_frglist.sh

by Andrei Gherzan

From: Andrei <andrei.gherzan(a)canonical.com> The udpgro_frglist.sh uses nat6to4.o which is tested for existence in bpf/nat6to4.o (relative to the script). This is where the object is compiled. Even so, the script attempts to use it as part of tc with a different path (../bpf/nat6to4.o). As a consequence, this fails the script: Error opening object ../bpf/nat6to4.o: No such file or directory Cannot initialize ELF context! Unable to load program This change refactors these references to use a variable for consistency and also reformats two long lines.

[for-next][PATCH 02/12] tracing/selftests: Add test for event filtering on function name

by Steven Rostedt

From: "Steven Rostedt (Google)" <rostedt(a)goodmis.org> With the new filter logic of passing in the name of a function to match an instruction pointer (or the address of the function), add a test to make sure that it is functional. This is also the first test to test plain filtering. The filtering has been tested via the trigger logic, which uses the same code, but there was nothing to test just the event filter, so this test is the first to add such a case.

Note: I've partially sent this patchset earlier due to a mistake on my side, sorry for then noise. The main goal of the patchset is to prepare bpfilter for iptables' configuration blob parsing and code generation. The patchset introduces data structures and code for matches, targets, rules and tables. Beside that the code generation is introduced. The first version of the code generation supports only "inline" mode - all chains and their rules emit instructions in linear approach. Things that are not implemented yet: 1) The process of switching from the previous BPF programs to the new set isn't atomic. 2) No support of device ifindex - it's hardcoded 3) No helper subprog for counters update Another problem is using iptables' blobs for tests and filter table initialization. While it saves lines something more maintainable should be done here. The plan for the next iteration: 1) Add a helper program for counters update 2) Handle ifindex Patches 1/2 adds definitions of the used types. Patch 3 adds logging to bpfilter. Patch 4 adds an associative map. Patch 5 add runtime context structure. Patches 6/7 add code generation infrastructure and TC code generator. Patches 8/9/10/11/12 add code for matches, targets, rules and table. Patch 13 adds code generation for table. Patch 14 handles hooked setsockopt(2) calls. Patch 15 adds filter table Patch 16 uses prepared code in main(). Due to poor hardware availability on my side, I've not been able to benchmark those changes. I plan to get some numbers for the next iteration. FORWARD filter chain is now supported, however, it's attached to TC INGRESS along with INPUT filter chain. This is due to XDP not supporting multiple programs to be attached. I could generate a single program out of both INPUT and FORWARD chains, but that would prevent another BPF program to be attached to the interface anyway. If a solution exists to attach both those programs to XDP while allowing for other programs to be attached, it requires more investigation. In the meantime, INPUT and FORWARD filtering is supported using TC. Most of the code in this series was written by Dmitrii Banshchikov, my changes are limited to v3. I've tried to reflect this fact in the commits by adding 'Co-developed-by:' and 'Signed-off-by:' for Dmitrii, please tell me this was done the wrong way. v2 -> v3 Chains: * Add support for FORWARD filter chain. * Add generation of BPF bytecode to assess whether a packet should be forwarded or not, using bpf_fib_lookup(). * Allow for multiple programs to be attached to TC. * Allow for multiple TC hooks to be used. Code generation: * Remove duplicated BPF bytecode generation. * Fix a bug regarding jump offset during generation. * Remove support for XDP from the series, as it's not currently used. Table: * Add new filter_table_update_counters() virtual call. It updates the table's counter stored in the ipt_entry structure. This way, when iptables tries to fetch the values of the counters, bpfilter only has to copy the ipt_entry cached in the table structure. Logging: * Refactor logging primitives. Sockopts: * Add support for userspace counters querying. Rule: * Store the rule's index inside struct rule, to each counters' map usage. v1 -> v2 Maps: * Use map_upsert instead of separate map_insert and map_update Matches: * Add a new virtual call - gen_inline. The call is used for * inline generating of a rule's match. Targets: * Add a new virtual call - gen_inline. The call is used for inline generating of a rule's target. Rules: * Add code generation for rules Table: * Add struct table_ops * Add map for table_ops * Add filter table * Reorganize the way filter table is initialized Sockopts: * Install/uninstall BPF programs while handling IPT_SO_SET_REPLACE Code generation: * Add first version of the code generation Dependencies: * Add libbpf v0 -> v1 IO: * Use ssize_t in pvm_read, pvm_write for total_bytes * Move IO functions into sockopt.c and main.c Logging: * Use LOGLEVEL_EMERG, LOGLEVEL_NOTICE, LOGLEVE_DEBUG while logging to /dev/kmsg * Prepend log message with <n> where n is log level * Conditionally enable BFLOG_DEBUG messages * Merge bflog.{h,c} into context.h Matches: * Reorder fields in struct match_ops for tight packing * Get rid of struct match_ops_map * Rename udp_match_ops to xt_udp * Use XT_ALIGN macro * Store payload size in match size * Move udp match routines into a separate file Targets: * Reorder fields in struct target_ops for tight packing * Get rid of struct target_ops_map * Add comments for convert_verdict function Rules: * Add validation Tables: * Combine table_map and table_list into table_index * Add validation Sockopts: * Handle IPT_SO_GET_REVISION_TARGET 1. https://lore.kernel.org/patchwork/patch/902785/ 2. https://lore.kernel.org/patchwork/patch/902783/ 3. https://kernel.ubuntu.com/~cking/stress-ng/stress-ng.pdf Quentin Deslandes (16): bpfilter: add types for usermode helper tools: add bpfilter usermode helper header bpfilter: add logging facility bpfilter: add map container bpfilter: add runtime context bpfilter: add BPF bytecode generation infrastructure bpfilter: add support for TC bytecode generation bpfilter: add match structure bpfilter: add support for src/dst addr and ports bpfilter: add target structure bpfilter: add rule structure bpfilter: add table structure bpfilter: add table code generation bpfilter: add setsockopt() support bpfilter: add filter table bpfilter: handle setsockopt() calls include/uapi/linux/bpfilter.h | 154 +++ net/bpfilter/Makefile | 16 +- net/bpfilter/codegen.c | 1040 +++++++++++++++++ net/bpfilter/codegen.h | 183 +++ net/bpfilter/context.c | 168 +++ net/bpfilter/context.h | 24 + net/bpfilter/filter-table.c | 344 ++++++ net/bpfilter/filter-table.h | 18 + net/bpfilter/logger.c | 52 + net/bpfilter/logger.h | 80 ++ net/bpfilter/main.c | 132 ++- net/bpfilter/map-common.c | 51 + net/bpfilter/map-common.h | 19 + net/bpfilter/match.c | 55 + net/bpfilter/match.h | 37 + net/bpfilter/rule.c | 286 +++++ net/bpfilter/rule.h | 37 + net/bpfilter/sockopt.c | 533 +++++++++ net/bpfilter/sockopt.h | 15 + net/bpfilter/table.c | 391 +++++++ net/bpfilter/table.h | 59 + net/bpfilter/target.c | 203 ++++ net/bpfilter/target.h | 57 + net/bpfilter/xt_udp.c | 111 ++ tools/include/uapi/linux/bpfilter.h | 175 +++ .../testing/selftests/bpf/bpfilter/.gitignore | 8 + tools/testing/selftests/bpf/bpfilter/Makefile | 57 + .../selftests/bpf/bpfilter/bpfilter_util.h | 80 ++ .../selftests/bpf/bpfilter/test_codegen.c | 338 ++++++ .../testing/selftests/bpf/bpfilter/test_map.c | 63 + .../selftests/bpf/bpfilter/test_match.c | 69 ++ .../selftests/bpf/bpfilter/test_rule.c | 56 + .../selftests/bpf/bpfilter/test_target.c | 83 ++ .../selftests/bpf/bpfilter/test_xt_udp.c | 48 + 34 files changed, 4999 insertions(+), 43 deletions(-) create mode 100644 net/bpfilter/codegen.c create mode 100644 net/bpfilter/codegen.h create mode 100644 net/bpfilter/context.c create mode 100644 net/bpfilter/context.h create mode 100644 net/bpfilter/filter-table.c create mode 100644 net/bpfilter/filter-table.h create mode 100644 net/bpfilter/logger.c create mode 100644 net/bpfilter/logger.h create mode 100644 net/bpfilter/map-common.c create mode 100644 net/bpfilter/map-common.h create mode 100644 net/bpfilter/match.c create mode 100644 net/bpfilter/match.h create mode 100644 net/bpfilter/rule.c create mode 100644 net/bpfilter/rule.h create mode 100644 net/bpfilter/sockopt.c create mode 100644 net/bpfilter/sockopt.h create mode 100644 net/bpfilter/table.c create mode 100644 net/bpfilter/table.h create mode 100644 net/bpfilter/target.c create mode 100644 net/bpfilter/target.h create mode 100644 net/bpfilter/xt_udp.c create mode 100644 tools/include/uapi/linux/bpfilter.h create mode 100644 tools/testing/selftests/bpf/bpfilter/.gitignore create mode 100644 tools/testing/selftests/bpf/bpfilter/Makefile create mode 100644 tools/testing/selftests/bpf/bpfilter/bpfilter_util.h create mode 100644 tools/testing/selftests/bpf/bpfilter/test_codegen.c create mode 100644 tools/testing/selftests/bpf/bpfilter/test_map.c create mode 100644 tools/testing/selftests/bpf/bpfilter/test_match.c create mode 100644 tools/testing/selftests/bpf/bpfilter/test_rule.c create mode 100644 tools/testing/selftests/bpf/bpfilter/test_target.c create mode 100644 tools/testing/selftests/bpf/bpfilter/test_xt_udp.c -- 2.38.1

[PATCH v5 0/3] Checkpoint Support for Syscall User Dispatch

by Gregory Price

v5: automated test for !defined(GENERIC_ENTRY) failed, fix fs/proc use ifdef for GENERIC_ENTRY || TIF_SYSCALL_USER_DISPATCH note: syscall user dispatch is not presently supported for non-generic entry, but could be implemented. question is whether the TIF_ define should be carved out now or then v4: Whitespace s/CHECKPOINT_RESTART/CHECKPOINT_RESUME check test_syscall_work(SYSCALL_USER_DISPATCH) to determine if it's turned on or not in fs/proc/array and getter interface v3: Kernel test robot static function fix Whitespace nitpicks v2: Implements the getter/setter interface in ptrace rather than prctl Syscall user dispatch makes it possible to cleanly intercept system calls from user-land. However, most transparent checkpoint software presently leverages some combination of ptrace and system call injection to place software in a ready-to-checkpoint state. If Syscall User Dispatch is enabled at the time of being quiesced, injected system calls will subsequently be interposed upon and dispatched to the task's signal handler. This patch set implements 3 features to enable software such as CRIU to cleanly interpose upon software leveraging syscall user dispatch. - Implement PTRACE_O_SUSPEND_SYSCALL_USER_DISPATCH, akin to a similar feature for SECCOMP. This allows a ptracer to temporarily disable syscall user dispatch, making syscall injection possible. - Implement an fs/proc extension that reports whether Syscall User Dispatch is being used in proc/status. A similar value is present for SECCOMP, and is used to determine whether special logic is needed during checkpoint/resume. - Implement a getter interface for Syscall User Dispatch config info. To resume successfully, the checkpoint/resume software has to save and restore this information. Presently this configuration is write-only, with no way for C/R software to save it. This was done in ptrace because syscall user dispatch is not part of uapi. The syscall_user_dispatch_config structure was added to the ptrace exports.

[PATCH v5 0/5] Some improvements of resctrl selftest

by Shaopeng Tan

Hello, The aim of this patch series is to improve the resctrl selftest. Without these fixes, some unnecessary processing will be executed and test results will be confusing. There is no behavior change in test themselves. [patch 1] Make write_schemata() run to set up shemata with 100% allocation on first run in MBM test. [patch 2] The MBA test result message is always output as "ok", make output message to be "not ok" if MBA check result is failed. [patch 3] When a child process is created by fork(), the buffer of the parent process is also copied. Flush the buffer before executing fork(). [patch 4] Add a signal handler to cleanup properly before exiting the parent process if there is an error occurs after creating a child process with fork() in the CAT test, and unregister signal handler when each test finished. [patch 5] Before exiting each test CMT/CAT/MBM/MBA, clear test result files function cat/cmt/mbm/mba_test_cleanup() are called twice. Delete once. This patch series is based on Linux v6.2-rc3. Difference from v4: [patch 4] - Reuse signal handler of other tests(MBM/MBA/CAT). - Unregister signal handler when tests finished. - Fix change log.

[PATCH AUTOSEL 6.1 12/35] kselftest: Fix error message for unconfigured LLVM builds

From: Mark Brown <broonie(a)kernel.org> [ Upstream commit 9fdaca2c1e157dc0a3c0faecf3a6a68e7d8d0c7b ] We are missing a ) when we attempt to complain about not having enough configuration for clang, resulting in the rather inscrutable error: ../lib.mk:23: *** unterminated call to function 'error': missing ')'.

[PATCH 0/2] selftests/nolibc: small simplification of test development phase

by Willy Tarreau

Hello Paul, while developing and testing the recent changes for errno/environ/auxv, I found that I wasn't relying on the kernel that much and that I was mostly using qemu in userland only with my local kernel. I figured that it was more convenient for this purpose than rebuilding an initramfs and kernel for a quick test, and decided to make this approach easier to use for everyone by adding a "run-user" target to the Makefile to do exactly this. E.g: Native build: $ time make -C tools/testing/selftests/nolibc run-user ... make: Entering directory '/g/public/linux/master/tools/testing/selftests/nolibc' MKDIR sysroot/x86/include make[1]: Entering directory '/g/public/linux/master/tools/include/nolibc' make[2]: Entering directory '/g/public/linux/master' make[2]: Leaving directory '/g/public/linux/master' make[2]: Entering directory '/g/public/linux/master' INSTALL /g/public/linux/master/tools/testing/selftests/nolibc/sysroot/sysroot/include make[2]: Leaving directory '/g/public/linux/master' make[1]: Leaving directory '/g/public/linux/master/tools/include/nolibc' CC nolibc-test 18 chroot_root = -1 EPERM [FAIL] 43 link_dir = -1 EACCES != (-1 EPERM) [FAIL] See all results in /g/public/linux/master/tools/testing/selftests/nolibc/run.out make: Leaving directory '/g/public/linux/master/tools/testing/selftests/nolibc' real 0m0.966s user 0m0.731s sys 0m0.164s Cross build: $ time make -C tools/testing/selftests/nolibc run-user ARCH=s390 CROSS_COMPILE=/f/tc/nolibc/gcc-11.3.0-nolibc/s390-linux/bin/s390-linux- make: Entering directory '/g/public/linux/master/tools/testing/selftests/nolibc' MKDIR sysroot/s390/include make[1]: Entering directory '/g/public/linux/master/tools/include/nolibc' make[2]: Entering directory '/g/public/linux/master' make[2]: Leaving directory '/g/public/linux/master' make[2]: Entering directory '/g/public/linux/master' INSTALL /g/public/linux/master/tools/testing/selftests/nolibc/sysroot/sysroot/include make[2]: Leaving directory '/g/public/linux/master' make[1]: Leaving directory '/g/public/linux/master/tools/include/nolibc' CC nolibc-test 18 chroot_root = -1 EPERM [FAIL] 43 link_dir = -1 EACCES != (-1 EPERM) [FAIL] See all results in /g/public/linux/master/tools/testing/selftests/nolibc/run.out make: Leaving directory '/g/public/linux/master/tools/testing/selftests/nolibc' real 0m1.014s user 0m0.732s sys 0m0.183s In addition, the "x86_64" value for ARCH= is now supported as I got caught too many times with it not working in this subdir while it's used for the rest of the kernel ("x86" is used instead as coming from subarch.include). Generally you don't type it as x86_64 probably is the native build for most users, but when you start to test toolchains it's a different thing. There's no matter of urgency for these patches, they're just a bit of user-friendly stuff. As such, if you're fine with stacking them on top of what you already have for 6.3, that will be great, otherwise they can easily wait. Thank you! Willy [CCing Ammar who could benefit from this] --- Willy Tarreau (2): selftests/nolibc: support "x86_64" for arch name selftests/nolibc: add a "run-user" target to test the program in user land tools/testing/selftests/nolibc/Makefile | 10 ++++++++++ 1 file changed, 10 insertions(+) -- 2.17.5

[PATCH] selftests: iommu: Fix test_cmd_destroy_access() call in user_copy

The test_cmd_destroy_access() should end with a semicolon, so add one. There is a test_ioctl_destroy(ioas_id) following already, so drop one.

[PATCH RFC 0/3] vsock: add support for sockmap

by Bobby Eshleman

Add support for sockmap to vsock. We're testing usage of vsock as a way to redirect guest-local UDS requests to the host and this patch series greatly improves the performance of such a setup. Compared to copying packets via userspace, this improves throughput by 221% in basic testing. Tested as follows. Setup: guest unix dgram sender -> guest vsock redirector -> host vsock server Threads: 1 Payload: 64k No sockmap: - 76.3 MB/s - The guest vsock redirector was "socat VSOCK-CONNECT:2:1234 UNIX-RECV:/path/to/sock" Using sockmap (this patch): - 168.8 MB/s (+221%) - The guest redirector was a simple sockmap echo server, redirecting unix ingress to vsock 2:1234 egress. - Same sender and server programs Only the virtio transport has been tested. The loopback transport was used in writing bpf/selftests, but not thoroughly tested otherwise. This series requires the skb patch.

[PATCH v4 0/3] Checkpoint Support for Syscall User Dispatch

by Gregory Price

v4: Whitespace s/CHECKPOINT_RESTART/CHECKPOINT_RESUME check test_syscall_work(SYSCALL_USER_DISPATCH) to determine if it's turned on or not in fs/proc/array and getter interface v3: Kernel test robot static function fix Whitespace nitpicks v2: Implements the getter/setter interface in ptrace rather than prctl Syscall user dispatch makes it possible to cleanly intercept system calls from user-land. However, most transparent checkpoint software presently leverages some combination of ptrace and system call injection to place software in a ready-to-checkpoint state. If Syscall User Dispatch is enabled at the time of being quiesced, injected system calls will subsequently be interposed upon and dispatched to the task's signal handler. This patch set implements 3 features to enable software such as CRIU to cleanly interpose upon software leveraging syscall user dispatch. - Implement PTRACE_O_SUSPEND_SYSCALL_USER_DISPATCH, akin to a similar feature for SECCOMP. This allows a ptracer to temporarily disable syscall user dispatch, making syscall injection possible. - Implement an fs/proc extension that reports whether Syscall User Dispatch is being used in proc/status. A similar value is present for SECCOMP, and is used to determine whether special logic is needed during checkpoint/resume. - Implement a getter interface for Syscall User Dispatch config info. To resume successfully, the checkpoint/resume software has to save and restore this information. Presently this configuration is write-only, with no way for C/R software to save it. This was done in ptrace because syscall user dispatch is not part of uapi. The syscall_user_dispatch_config structure was added to the ptrace exports.
