* PR10099: Extend %M directive to support hexdumping large buffersWenji Huang2009-04-263-13/+34
| | | | | | | | | | This patch will make %M directive dump the variable width buffer in hex format instead of returning uint64_t number as before. * runtime/vsprintf.c: Modify %M directive. * stap.1.in: Update description. * testsuite/systemtap.printf/memory1.stp: Add test case.
* Add function of returning the char in given position of stringWenji Huang2009-04-263-1/+14
| | | | | | * tapset/string.stp: New function stringat. * testsuite/systemtap.printf/char1.exp: Update test case. * testsuite/systemtap.printf/char1.stp: Ditto.
* Handle kprobe struct field symbol_name as either char * or const char *.Mark Wielaard2009-04-261-2/+2
| | | | | | | | Older (2.6.18) based kernels defined struct kprobes symbol_name as char *, but newer (2.6.27) based kernels defined the same field as const char *. * tapsets.cxx (kprobe_derived_probe_group::emit_module_init): Always cast to char * when assigning to kprobes.symbol_name field.
* fix kprobe.* probes so they don't break -p4 if script also has kernel.* probesFrank Ch. Eigler2009-04-262-6/+10
| | | | | * tapsets.cxx (kprobe_derived_probe): Use enter_k[ret]probe>>2<<_probe. * testsuite/buildok/thirtyone.stp: Test this.

* Correct fd variable name in fadvise64 probe points.Przemyslaw Pawelczyk2009-04-251-4/+4
| | | | * tapset/syscalls.stp: Rename fs variable to fd.
* Enable kprobe.function.return.maxactiveJosh Stone2009-04-241-35/+57
| | | | | The code to emit maxactive was almost there; it just needed to enable the maxactive probe component and pass the value down.
* Simplify dwarfless kprobe stmt vs. name logicJosh Stone2009-04-241-29/+15

* Fill out the pp() for dwarfless kprobesJosh Stone2009-04-241-3/+25
|
* Don't terminate when a dwarfless kprobe failsJosh Stone2009-04-242-17/+24
| | | | | | | | | | All of our other kprobe types will let the script continue after a registration failure, as per PR6749. The dwarfless kprobes should be no exception. Also, the way they were exiting was causing an unclean shutdown, so I added tests to badkprobe.exp to make sure that cleanup is always allowed to run.

* PR5273: uprobes_i386.c instruction tableJim Keniston2009-04-241-11/+11
| | | | | Resynch uprobes1 2-byte-opcode table with uprobes2 x86. Mostly changes a bunch of mmx instructions from rejected to accepted.
* Cache and retrieve syscall arguments when needed.David Smith2009-04-242-35/+293
| | | | | | | | | | | | * runtime/task_finder.c (__stp_utrace_task_finder_target_syscall_entry): New function that caches syscall arguments for mmap(), munmap(), and mprotect() for use in __stp_utrace_task_finder_target_syscall_exit(). (__stp_utrace_task_finder_target_syscall_exit): Uses cached syscall argument info when making callbacks. (stap_start_task_finder): Initializes map subsytem for storing syscall argument data. * runtime/task_finder_map.c: New file containing functions to save and retrieve syscall arguments.

| * [tracepoints] Resolve implicit trace_X useJosh Stone2009-04-211-1/+2
| | | | | | | | | | | | | | Some of the tracepoints are actually being called in inlines in the common headers (e.g. trace_kmalloc), which is causing errors about implicit function declarations. We don't care about ever running the code in the tracequery module, so I'm just suppressing that error.
| * [tracepoints] Don't use TRACE_HEADER_MULTI_READJosh Stone2009-04-211-4/+0
| | | | | | | | | | | | | | At one point that macro was needed to get all of the tracepoints on the tip tree, but now it's causing us to get duplicate stapprobe_X definitions. AFAICS, we're now getting all tracepoints even without MULTI_READ, so I'm pulling that workaround out.

| * Refine the @cast-with-header syntaxJosh Stone2009-04-215-25/+45
| | | | | | | | | | | | | | The special syntax to generate a module for type information is now: - "kernel<path/to/header.h>" to use the kernel's build environment - "<path/to/header.h>" to use no special build environment, and so use gcc's default parameters only (for user mode).

| | | | | | | | | | | | | | | | Needs extra space since on 64bit the last ubacktrace string is 7 entries * (16 hex + 2 for 0x + 1 space) = 133 chars. Default MAXSTRINGLEN is 128 chars. * testsuite/systemtap.base/uprobes_ustack.exp: Add -DMAXSTRINGLEN.
