* Remove documentation weirdness FIXME in tapset print_stack().Mark Wielaard2009-04-211-2/+2
| | | | | | Weirdness was fixed in commit d4db5608. * tapset/context-symbols.stp (print_stack): Remove FIXME.
* Don't use stack fallback for user space unwinding when using dwarf unwinder.Mark Wielaard2009-04-212-8/+16
| | | | | | | | It never seems to be anywhere near correct. * runtime/stack-i386.c (__stp_stack_print): Stop unwinding when dwarf unwinder fails and we are unwinding user space task. * runtime/stack-x86_64.c (__stp_stack_print): Likewise.
* Remove old _stp_ustack bits.Mark Wielaard2009-04-211-17/+0
| | | | | | This code was never used, nor did it actually work. * runtime/stack.c (_stp_ustack_print): Removed.
* Pass task from tapset, through stack and unwind functions for lookup.Mark Wielaard2009-04-209-21/+27
| | | | | | | | | | | | | | | | | * runtime/stack-arm.c (__stp_stack_print): Take struct task_struct *. * runtime/stack-ia64.c (__stp_stack_print): Likewise. * runtime/stack-ppc64.c (__stp_stack_print): Likewise. * runtime/stack-s390.c (__stp_stack_print): Likewise. * runtime/stack-i386.c (__stp_stack_print): Likewise. And add check and pass to unwind() and _stp_func_print(). * runtime/stack-x86_64.c: Likewise. * runtime/stack.c *_stp_stack_print): Take and pass on task_struct. (_stp_stack_snprint): Likewise. * runtime/unwind.c (unwind): Take and use task_struct for _stp_mod_sec_lookup(). * tapset/context-unwind.stp (print_backtrace): Pass NULL to _stp_stack_print(). (backtrace): Pass NULL to _stp_stack_snprint().
* Add comment to try -d kernel -d systemtap_test_module1 on backtrace.tcl test.Mark Wielaard2009-04-201-0/+1

* Pass task to _stp_func_print and _stp_kallsyms_lookup.Mark Wielaard2009-04-194-8/+9
| | | | | | | | | * runtime/sym.c (_stp_func_print): Take task, pass to _stp_kallsyms_lookup. * runtime/stack.c (print_stack_address): Pass NULL. * runtime/stack-i386.c (_stp_stack_print_fallback): Pass NULL. (__stp_stack_print): Pass NULL or current. * runtime/stack-x86_64.c (_stp_stack_print_fallback): Pass NULL. (__stp_stack_print): Pass current.
* Handle .absolute and .dynamic (user space) addresses in adjustStartLoc.Mark Wielaard2009-04-191-6/+12
| | | | | * runtime/unwind.c (adjustStartLoc): .absolute sections don't need adjustment, .dynamic sections need the section addr to be added.
* Micro-optimization: no-modules translate pass 3 case.Mark Wielaard2009-04-191-8/+22
| | | | | | | | Saves 250ms in the unlikely case there are no modules needed. * translate.cxx (emit_symbol_data_done): New function. (emit_symbol_data): Call emit_symbol_data_done immediately when no module data is needed.
* Remove module boilerplate from tracequeryJosh Stone2009-04-171-5/+0
| | | | | | | Kernel modules will actually build just fine with none of the module boilerplate code. We don't care about ever actually loading the tracequery module that we make, so don't bother emitting code we don't need.

| | | | | | | | * dtrace: Output probe calling sequence comment
| * Keep up with tracepoint changes in kernel-tipJosh Stone2009-04-161-5/+19
| | | | | | | | | | | | | | | | - Define TRACE_HEADER_MULTI_READ to allow re-pulling headers that were already included indirectly elsewhere. - Some tracepoint headers were moved down to include/trace/events/, so add that to our glob paths. - Add ftrace.h as a header that we should never include.
| * Privatize MAX_STACK_DEPTHJosh Stone2009-04-162-3/+3
| | | | | | | | | | | | The kernel-tip tree also has a MAX_STACK_DEPTH defined in perf_counter.h, so we need to separate our definition. I've changed the definition in our unwinder to STP_MAX_STACK_DEPTH.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds some basic functions to the IP and TCP tapsets. Mainly, it's possible to get the iphdr and tcphdr from a sk_buff structure. As a consequence, a TCP probe called tcp.receive() was created and is probed every time a TCP packet is received, and a lot of useful fields is available, as the TCP flags. Also a small example that works like tcpdump for received TCP packets was created. This patch was tested on x86 and ppc machines, on 2.6.18 kernel and also on mainline one.

Also be a bit more aggressive with masking and parentheses. * testsuite/systemtap.base/bitfield.*: New test for R/W bitfields.
| * | PR10049: Restore better errors for $returnJosh Stone2009-04-131-10/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit c4ce66a1 I shifted some of the variable accesses around, and that caused the error messages for $return variables to lose context. The root problem in this case was that dwarf_attr didn't find the type attribute, and that failure wasn't immediately caught. Now that result is checked so we can provide a proper error message. While I'm at it, changing that lookup to dwarf_attr_integrate is enough to make the $return value usable again, at least for the reported test case.

| * Make simple probes work even without KPROBES in the kernel.Mark Wielaard2009-04-091-0/+8
| | | | | | | | | | | | | | | | | | Without KPROBES very little works atm. But stack.c file is unconditionally imported, while these two functions are only used through context-unwind.stp. This at least lets us do simple sanity checks on "plain" kernels. * runtime/stack.c (_stp_stack_print, _stp_stack_snprint): Wrap in #if defined (CONFIG_KPROBES).
