Torvalds <torvalds@linux-foundation.org> # Date: Tue Oct 30 09:49:56 2018 -0700 # # Merge tag 'trace-v4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace # # Pull tracing updates from Steven Rostedt: # "The biggest change here is the updates to kprobes # # Back in January I posted patches to create function based events. # These were the events that you suggested I make to allow developers to # easily create events in code where no trace event exists. 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
