[PATCH v2 tracing 0/6] tracing: additional filter predicates

by Alan Maguire

For cases like IPv6 addresses, having a means to supply tracing predicates for fields with more than 8 bytes would be convenient. This series provides a simple way to support this by allowing simple ==, != memory comparison with the predicate supplied when the size of the field exceeds 8 bytes. For example, to trace ::1, the predicate "dst == 0x00000000000000000000000000000001" ..could be used. Patch 1 implements this. As a convenience, support for IPv4, IPv6 and MAC addresses are also included; patches 2-4 cover these and allow simpler comparisons which do not require getting the exact number of bytes right; for exmaple "dst == ::1" "src != 127.0.0.1" "mac_addr == ab:cd:ef:01:23:45" Patch 5 adds tests for existing and new filter predicates, and patch 6 documents the fact that for the various addresses supported and the >8 byte memory comparison. only == and != are supported. Changes since v1 [1]: - added support for IPv4, IPv6 and MAC addresses (patches 2-4) (Masami and Steven) - added selftests for IPv4, IPv6 and MAC addresses and updated docs accordingly (patches 5,6) Changes since RFC [2]: - originally a fix was intermixed with the new functionality as patch 1 in series [2]; the fix landed separately - small tweaks to how filter predicates are defined via fn_num as opposed to via fn directly [1] https://lore.kernel.org/linux-trace-kernel/1682414197-13173-1-git-send-emai… [22] https://lore.kernel.org/lkml/1659910883-18223-1-git-send-email-alan.maguire… Alan Maguire (6): tracing: support > 8 byte array filter predicates tracing: support IPv4 address filter predicate tracing: support IPv6 filter predicates tracing: support MAC address filter predicates selftests/ftrace: add test coverage for filter predicates tracing: document IPv4, IPv6, MAC address and > 8 byte numeric filtering support Documentation/trace/events.rst | 21 +++ kernel/trace/trace_events_filter.c | 164 +++++++++++++++++- .../selftests/ftrace/test.d/event/filter.tc | 91 ++++++++++ 3 files changed, 275 insertions(+), 1 deletion(-) create mode 100644 tools/testing/selftests/ftrace/test.d/event/filter.tc -- 2.31.1

[PATCH net v2 0/3] Check if FIPS mode is enabled when running selftests

by Magali Lemes

Some test cases from net/tls, net/fcnal-test and net/vrf-xfrm-tests that rely on cryptographic functions to work and use non-compliant FIPS algorithms fail in FIPS mode. In order to allow these tests to pass in a wider set of kernels, - for net/tls, skip the test variants that use the ChaCha20-Poly1305 and SM4 algorithms, when FIPS mode is enabled; - for net/fcnal-test, skip the MD5 tests, when FIPS mode is enabled; - for net/vrf-xfrm-tests, replace the algorithms that are not FIPS-compliant with compliant ones. Changes in v2: - Add R-b tags. - Put fips_non_compliant into the variants. - Turn fips_enabled into a static global variable. - Read /proc/sys/crypto/fips_enabled only once at main(). v1: https://lore.kernel.org/netdev/20230607174302.19542-1-magali.lemes@canonica… Magali Lemes (3): selftests: net: tls: check if FIPS mode is enabled selftests: net: vrf-xfrm-tests: change authentication and encryption algos selftests: net: fcnal-test: check if FIPS mode is enabled tools/testing/selftests/net/fcnal-test.sh | 27 ++- tools/testing/selftests/net/tls.c | 175 +++++++++++++++++- tools/testing/selftests/net/vrf-xfrm-tests.sh | 32 ++-- 3 files changed, 209 insertions(+), 25 deletions(-) -- 2.34.1

[PATCH] selftests/cpufreq: Don't enable generic lock debugging options

by Mark Brown

Currently the the config fragment for cpufreq enables a lot of generic lock debugging. While these options are useful when testing cpufreq they aren't actually required to run the tests and are therefore out of scope for the cpufreq fragement, they are more of a thing that it's good to enable while doing testing than an actual requirement for cpufreq testing specifically. Having these debugging options enabled, especially the mutex and spinlock instrumentation, mean that any build that includes the cpufreq fragment is both very much larger than a standard defconfig (eg, I'm seeing 35% on x86_64) and also slower at runtime. This is causing real problems for CI systems. In order to avoid building large numbers of kernels they try to group kselftest fragments together, frequently just grouping all the kselftest fragments into a single block. The increased size is an issue for memory constrained systems and is also problematic for systems with fixed storage allocations for kernel images (eg, typical u-boot systems) where it frequently causes the kernel to overflow the storage space allocated for kernels. The reduced performance isn't too bad with real hardware but can be disruptive on emulated platforms. In order to avoid these issues remove these generic instrumentation options from the cpufreq fragment, bringing the cpufreq fragment into line with other fragments which generally set requirements for testing rather than nice to haves.

[PATCH v2] HID: uclogic: Modular KUnit tests should not depend on KUNIT=y

by Geert Uytterhoeven

While KUnit tests that cannot be built as a loadable module must depend on "KUNIT=y", this is not true for modular tests, where it adds an unnecessary limitation. Fix this by relaxing the dependency to "KUNIT".

[RFC PATCH] asm-generic: Unify uapi bitsperlong.h

by Tiezhu Yang

Now we specify the minimal version of GCC as 5.1 and Clang/LLVM as 11.0.0 in Documentation/process/changes.rst, __CHAR_BIT__ and __SIZEOF_LONG__ are usable, just define __BITS_PER_LONG as (__CHAR_BIT__ * __SIZEOF_LONG__) in asm-generic uapi bitsperlong.h, simpler, works everywhere. Remove all the arch specific uapi bitsperlong.h which will be generated as arch/*/include/generated/uapi/asm/bitsperlong.h.

[PATCH bpf-next v3 0/3] bpf, x86: allow function arguments up to 12 for TRACING

by menglong8.dong＠gmail.com

From: Menglong Dong <imagedong(a)tencent.com> For now, the BPF program of type BPF_PROG_TYPE_TRACING can only be used on the kernel functions whose arguments count less than 6. This is not friendly at all, as too many functions have arguments count more than 6. Therefore, let's enhance it by increasing the function arguments count allowed in arch_prepare_bpf_trampoline(), for now, only x86_64. In the 1st patch, we make arch_prepare_bpf_trampoline() support to copy function arguments in stack for x86 arch. Therefore, the maximum arguments can be up to MAX_BPF_FUNC_ARGS for FENTRY and FEXIT. In the 2nd patch, we clean garbage value in upper bytes of the trampoline when we store the arguments from regs into stack. And the 3rd patches are for the testcases of the 1st patch. Changes since v2: - keep MAX_BPF_FUNC_ARGS still - clean garbage value in upper bytes in the 2nd patch - move bpf_fentry_test{7,12} to bpf_testmod.c and rename them to bpf_testmod_fentry_test{7,12} meanwhile in the 3rd patch Changes since v1: - change the maximun function arguments to 14 from 12 - add testcases (Jiri Olsa) - instead EMIT4 with EMIT3_off32 for "lea" to prevent overflow Menglong Dong (3): bpf, x86: allow function arguments up to 12 for TRACING bpf, x86: clean garbage value in the stack of trampoline selftests/bpf: add testcase for FENTRY/FEXIT with 6+ arguments arch/x86/net/bpf_jit_comp.c | 105 +++++++++++++++--- .../selftests/bpf/bpf_testmod/bpf_testmod.c | 19 +++- .../selftests/bpf/prog_tests/fentry_fexit.c | 4 +- .../selftests/bpf/prog_tests/fentry_test.c | 2 + .../selftests/bpf/prog_tests/fexit_test.c | 2 + .../testing/selftests/bpf/progs/fentry_test.c | 21 ++++ .../testing/selftests/bpf/progs/fexit_test.c | 33 ++++++ 7 files changed, 169 insertions(+), 17 deletions(-) -- 2.40.1

[PATCH net 0/3] Check if FIPS mode is enabled when running selftests

by Magali Lemes

Some test cases from net/tls, net/fcnal-test and net/vrf-xfrm-tests that rely on cryptographic functions to work and use non-compliant FIPS algorithms fail in FIPS mode. In order to allow these tests to pass in a wider set of kernels, - for net/tls, skip the test variants that use the ChaCha20-Poly1305 and SM4 algorithms, when FIPS mode is enabled; - for net/fcnal-test, skip the MD5 tests, when FIPS mode is enabled; - for net/vrf-xfrm-tests, replace the algorithms that are not FIPS-compliant with compliant ones. Magali Lemes (3): selftests: net: tls: check if FIPS mode is enabled selftests: net: vrf-xfrm-tests: change authentication and encryption algos selftests: net: fcnal-test: check if FIPS mode is enabled tools/testing/selftests/net/fcnal-test.sh | 27 +- tools/testing/selftests/net/tls.c | 265 +++++++++++++++++- tools/testing/selftests/net/vrf-xfrm-tests.sh | 32 +-- 3 files changed, 298 insertions(+), 26 deletions(-) -- 2.34.1
