The tracepoints are # called under an rcu_read_lock() which does not allow faults that can # sleep. This limits the ability of tracepoint handlers to page fault # in user space system call parameters. Now these tracepoints have been # made "faultable", allowing the callbacks to fault in user space # parameters and record them. # # Note, only the infrastructure has been implemented. The consumers # (perf, ftrace, BPF) now need to have their code modified to allow # faults. # # - Fix up of BPF code for the tracepoint faultable logic # # - Update tracepoints to use the new static branch API # # - Remove trace_*_rcuidle() variants and the SRCU protection they used # # - Remove unused TRACE_EVENT_FL_FILTERED logic # # - Replace strncpy() with strscpy() and memcpy() # # - Use replace per_cpu_ptr(smp_processor_id()) with this_cpu_ptr() # # - Fix perf events to not duplicate samples when tracing is enabled # # - Replace atomic64_add_return(1, counter) with # atomic64_inc_return(counter) # # - Make stack trace buffer 4K instead of PAGE_SIZE # # - Remove TRACE_FLAG_IRQS_NOSUPPORT flag as it was never used # # - Get the true return address for function tracer when function graph # tracer is also running. # # When function_graph trace is running along with function tracer, the # parent function of the function tracer sometimes is # "return_to_handler", which is the function graph trampoline to record # the exit of the function. Use existing logic that calls into the # fgraph infrastructure to find the real return address. # # - Remove (un)regfunc pointers out of tracepoint structure # # - Added last minute bug fix for setting pending modules in stack # function filter. # # echo "write*:mod:ext3" > /sys/kernel/tracing/stack_trace_filter # # Would cause a kernel NULL dereference. # # - Minor clean ups # # * tag 'trace-v6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: (31 commits) # ftrace: Fix regression with module command in stack_trace_filter # tracing: Fix function name for trampoline # ftrace: Get the true parent ip for function tracer # tracing: Remove redundant check on field->field in histograms # bpf: ensure RCU Tasks Trace GP for sleepable raw tracepoint BPF links # bpf: decouple BPF link/attach hook and BPF program sleepable semantics # bpf: put bpf_link's program when link is safe to be deallocated # tracing: Replace strncpy() with strscpy() when copying comm # tracing: Add might_fault() check in __DECLARE_TRACE_SYSCALL # tracing: Fix syscall tracepoint use-after-free # tracing: Introduce tracepoint_is_faultable() # tracing: Introduce tracepoint extended structure # tracing: Remove TRACE_FLAG_IRQS_NOSUPPORT # tracing: Replace multiple deprecated strncpy with memcpy # tracing: Make percpu stack trace buffer invariant to PAGE_SIZE # tracing: Use atomic64_inc_return() in trace_clock_counter() # trace/trace_event_perf: remove duplicate samples on the first tracepoint event # tracing/bpf: Add might_fault check to syscall probes # tracing/perf: Add might_fault check to syscall probes # tracing/ftrace: Add might_fault check to syscall probes # ... # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux-ld --version # < git log --format=%s --max-count=1 06afb0f36106ecb839c5e2509905e68c1e2677de # make -s -j 160 ARCH=sh O=/kisskb/build/linus_allmodconfig_sh4-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # < make -s -j 160 ARCH=sh O=/kisskb/build/linus_allmodconfig_sh4-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux- help # make -s -j 160 ARCH=sh O=/kisskb/build/linus_allmodconfig_sh4-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux- olddefconfig # make -s -j 160 ARCH=sh O=/kisskb/build/linus_allmodconfig_sh4-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux- Generating include/generated/machtypes.h :1519:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S: Assembler messages: /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S:85: Warning: overflow in branch to __restore_all; converted into longer instruction sequence /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S:357: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S:360: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence /kisskb/src/kernel/fork.c: In function '__do_sys_clone3': /kisskb/src/kernel/fork.c:3078:2: error: #warning clone3() entry point is missing, please fix [-Werror=cpp] 3078 | #warning clone3() entry point is missing, please fix | ^~~~~~~ cc1: all warnings being treated as errors make[4]: *** [/kisskb/src/scripts/Makefile.build:229: kernel/fork.o] Error 1 make[4]: *** Waiting for unfinished jobs.... make[3]: *** [/kisskb/src/scripts/Makefile.build:478: kernel] Error 2 make[3]: *** Waiting for unfinished jobs.... {standard input}: Assembler messages: {standard input}: Warning: end of file not at end of a line; newline inserted {standard input}:1701: Error: unknown pseudo-op: `.cfi_def' {standard input}: Error: open CFI at the end of file; missing .cfi_endproc directive sh4-linux-gcc: internal compiler error: Segmentation fault signal terminated program cc1 Please submit a full bug report, with preprocessed source (by using -freport-bug).
