After # posting those changes for review, it was suggested that we implement # this instead with kprobes. # # The problem with kprobes is that the interface is too complex and # needs to be simplified. Masami Hiramatsu posted patches in March and # I've been playing with them a bit. There's been a bit of clean up in # the kprobe code that was inspired by the function based event patches, # and a couple of enhancements to the kprobe event interface. # # - If the arch supports it (we added support for x86), you can place a # kprobe event at the start of a function and use $arg1, $arg2, etc # to reference the arguments of a function. (Before you needed to # know what register or where on the stack the argument was). # # - The second is a way to see array of events. For example, if you # reference a mac address, you can add: # # echo 'p:mac ip_rcv perm_addr=+574($arg2):x8[6]' > kprobe_events # # And this will produce: # # mac: (ip_rcv+0x0/0x140) perm_addr={0x52,0x54,0x0,0xc0,0x76,0xec} # # Other changes include # # - Exporting trace_dump_stack to modules # # - Have the stack tracer trace the entire stack (stop trying to remove # tracing itself, as we keep removing too much). # # - Added support for SDT in uprobes" # # [ SDT - "Statically Defined Tracing" are userspace markers for tracing. # Let's not use random TLA's in explanations unless they are fairly # well-established as generic (at least for kernel people) - Linus ] # # * tag 'trace-v4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (24 commits) # tracing: Have stack tracer trace full stack # tracing: Export trace_dump_stack to modules # tracing: probeevent: Fix uninitialized used of offset in parse args # tracing/kprobes: Allow kprobe-events to record module symbol # tracing/kprobes: Check the probe on unloaded module correctly # tracing/uprobes: Fix to return -EFAULT if copy_from_user failed # tracing: probeevent: Add $argN for accessing function args # x86: ptrace: Add function argument access API # tracing: probeevent: Add array type support # tracing: probeevent: Add symbol type # tracing: probeevent: Unify fetch_insn processing common part # tracing: probeevent: Append traceprobe_ for exported function # tracing: probeevent: Return consumed bytes of dynamic area # tracing: probeevent: Unify fetch type tables # tracing: probeevent: Introduce new argument fetching code # tracing: probeevent: Remove NOKPROBE_SYMBOL from print functions # tracing: probeevent: Cleanup argument field definition # tracing: probeevent: Cleanup print argument functions # trace_uprobe: support reference counter in fd-based uprobe # perf probe: Support SDT markers having reference counter (semaphore) # ... # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-gcc --version # < git log --format=%s --max-count=1 343a9f35409b68b6de66ecd0db90a277aee90ec2 # < make -s -j 10 ARCH=um O=/kisskb/build/linus_um-allmodconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/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 # yes \n \| make -s -j 10 ARCH=um O=/kisskb/build/linus_um-allmodconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 oldconfig yes: standard output: Broken pipe # make -s -j 10 ARCH=um O=/kisskb/build/linus_um-allmodconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 /kisskb/src/scripts/unifdef.c: In function 'Mpass': /kisskb/src/scripts/unifdef.c:453:28: warning: 'strncpy' output truncated before terminating nul copying 4 bytes from a string of the same length [-Wstringop-truncation] static void Mpass (void) { strncpy(keyword, "if ", 4);
