But it fails to update the snapshot # buffer. If a snapshot takes place, the accounting for the ring buffer # being disabled is corrupted and this can lead to the ring buffer # being permanently disabled. # # - Add test case for snapshot and cpu mask working together # # - Fix memleak by the function graph tracer not getting closed properly. # # The iterator is used to read the ring buffer. When it opens, it calls # the open function of a tracer, and when it is closed, it calls the # close iteration. While a trace is being read, it is still possible to # change the tracer. # # If this happens between the function graph tracer and the wakeup # tracer (which uses function graph tracing), the tracers are not # closed properly during when the iterator sees the switch, and the # wakeup function did not initialize its private pointer to NULL, which # is used to know if the function graph tracer was the last tracer. It # could be fooled in thinking it is, but then on exit it does not call # the close function of the function graph tracer to clean up its data. # # - Fix synthetic events on big endian machines, by introducing a union # that does the conversions properly. # # - Fix synthetic events from printing out the number of elements in the # stacktrace when it shouldn't. # # - Fix synthetic events stacktrace to not print a bogus value at the # end. # # - Introduce a pipe_cpumask that prevents the trace_pipe files from # being opened by more than one task (file descriptor). # # There was a race found where if splice is called, the iter->ent could # become stale and events could be missed. There's no point reading a # producer/consumer file by more than one task as they will corrupt # each other anyway. Add a cpumask that keeps track of the per_cpu # trace_pipe files as well as the global trace_pipe file that prevents # more than one open of a trace_pipe file that represents the same ring # buffer. This prevents the race from happening. # # - Fix ftrace samples for arm64 to work with older compilers. # # * tag 'trace-v6.5-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: # samples: ftrace: Replace bti assembly with hint for older compiler # tracing: Introduce pipe_cpumask to avoid race on trace_pipes # tracing: Fix memleak due to race between current_tracer and trace # tracing/synthetic: Allocate one additional element for size # tracing/synthetic: Skip first entry for stack traces # tracing/synthetic: Use union instead of casts # selftests/ftrace: Add a basic testcase for snapshot # tracing: Fix cpu buffers unavailable due to 'record_disabled' missed # < /opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 4f9e7fabf8643003afefc172e62dd276686f016e # make -s -j 40 ARCH=um O=/kisskb/build/linus_allmodconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 allmodconfig # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_KCOV=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_GCC_PLUGIN_CYC_COMPLEXITY=n # Added to kconfig CONFIG_GCC_PLUGIN_SANCOV=n # Added to kconfig CONFIG_GCC_PLUGIN_LATENT_ENTROPY=n # Added to kconfig CONFIG_GCC_PLUGIN_STRUCTLEAK=n # Added to kconfig CONFIG_GCC_PLUGIN_RANDSTRUCT=n # Added to kconfig CONFIG_UML_NET=n # Added to kconfig CONFIG_UML_NET_ETHERTAP=n # Added to kconfig CONFIG_UML_NET_TUNTAP=n # Added to kconfig CONFIG_UML_NET_SLIP=n # Added to kconfig CONFIG_UML_NET_DAEMON=n # Added to kconfig CONFIG_UML_NET_VDE=n # Added to kconfig CONFIG_UML_NET_MCAST=n # Added to kconfig CONFIG_UML_NET_PCAP=n # Added to kconfig CONFIG_UML_NET_SLIRP=n # Added to kconfig CONFIG_GCOV_KERNEL=n # Added to kconfig CONFIG_DEBUG_INFO_BTF=n # Added to kconfig CONFIG_BPF_PRELOAD=n # Added to kconfig CONFIG_SPI_STM32_QSPI=n # < make -s -j 40 ARCH=um O=/kisskb/build/linus_allmodconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 help # make -s -j 40 ARCH=um O=/kisskb/build/linus_allmodconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 olddefconfig .config:12754:warning: override: reassigning to symbol GCC_PLUGIN_LATENT_ENTROPY .config:12758:warning: override: reassigning to symbol UML_NET_ETHERTAP .config:12760:warning: override: reassigning to symbol UML_NET_SLIP .config:12765:warning: override: reassigning to symbol UML_NET_SLIRP # make -s -j 40 ARCH=um O=/kisskb/build/linus_allmodconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 LINK linux Completed OK # rm -rf /kisskb/build/linus_allmodconfig_um-x86_64-gcc12 # Build took: 0:10:14.358005
