* | | | | PR10285. User space PROBE marks aren't found with separate debuginfo.Mark Wielaard2009-06-151-2/+1

It could end up searching the separate debuginfo twice instead of falling back to the main elf file. Now we explicitly search the main elf file first (where the .probes section really should be) and only then fall back to the separate debuginfo file. * tapsets.cxx (dwarf_builder::probe_table::probe_table): Search main elf file first, then fall back on separate debuginfo file if necessary. * testsuite/systemtap.exelib/exelib.exp: Enable mark.tcl testcase. main elf file or the debuginfo file, but would interpret

This does defeat part of the testcase though, which was testing unwinding through an optimized recursive function. But it seems the best we can do. * testsuite/systemtap.exelib/exelib.exp: Add -O3 to the mix. * testsuite/systemtap.exelib/uprobes_exe.c: Use volatile bar and mark main_func noinline. * testsuite/systemtap.exelib/uprobes_lib.c: Use volatile foo and mark lib_func noinline.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an instance of an alias has a condition, that condition gets propagated to each of the locations that the alias defines. However, the copy of the location list was not a deep copy, and so all other instances of the alias would also incorrectly receive the condition. This patch makes the location list copy a little deeper, and adds a test case which demonstrates the issue.

* | | | Fix another kernel/kprobe.function conflictJosh Stone2009-05-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Both kernel.function and kprobe.function were defining a global array stap_unreg_kprobes to use in bulk kprobes unregistration. The compiler allowed the duplicate definition as long as they were the same size, as it was when exercised in buildok/thirtyone. kprobe.function now uses a separate stap_unreg_kprobes2, and the testcase is modified to produce an imbalanced number of probes.

| | | | | | | | | | | | | | | | | | | | | | | | When a kernel.function or kprobe.function fails in registration, we usually print a WARNING and move on. With this patch, kprobes that have the optional '?' flag will not print any WARNING.

| * | | | PR10177: init/kill time in sleepy context onlyJosh Stone2009-05-203-29/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, _stp_init_time and _stp_kill_time were being called from begin/end/error probes, which will run with preemption disabled. The BUG reported on RT kernels showed that cpufreq_unregister_notifier can end up sleeping, which violates our preemption block. This patch moves the init/kill into systemtap_module_init/exit, where it is safe to sleep. The code maintains a new predicate with the define STAP_NEED_GETTIMEOFDAY, so we don't still incur any timer overhead if it's not used.

* | | Allow @cast failures to get optimized awayJosh Stone2009-05-081-0/+6
| | | | | | | | | | | | | | | | | | We have the saved_conversion_error field, but I wasn't using it. Now @cast errors are saved in that field, so they're only seen if the optimizer doesn't remove the @cast.
* | | Refactor anonymous lookups in translate_componentsJosh Stone2009-05-081-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous code recursed the entirety of translate_components, and it seemed to be restarting the components list every time, so it would only work if the anonymous portion was the first component. Even then, examining the code output by semok/thirtythree revealed that it wasn't fully translating the locations when multiple anonymous pieces were involved. Instead, it now recurses in a separate function, find_struct_member, which does just enough to find the member die and return. It also builds a vector of the locations passed through, so translate_components can output code for the full chain of anonymity. The generated code for semok/thirtythree's $page->mapping now appears to match the offsets from my manual inspection of struct page. I also added a test for $page->first_page->mapping, which works now but would segfault the old code.
* | | Simplify buildok/context_test.stpJosh Stone2009-05-081-20/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The test was using optional probes on uptime_read_proc, which doesn't exist anymore on 2.6.30. The problem is that when those optional probes are skipped, the test doesn't really do anything. For a buildok test of the context functions, the actual probe point doesn't matter, so I've changed it to just a begin probe that calls all of the functions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The syscall testsuite uses embedded "// TEXT" markers in the .c files to designate expected output, kind of like the "dg-" bunch in the gcc test suite. Unfortunately, "//" is not a unique prefix to systemtap tests, and in particular it can occur in the system headers that will be picked up with the "gcc -E -C ..." invocation in test.tcl. So let's switch to "//staptest//". test.tcl is also modified to escape a few more mischevious regexp metacharacters that might sneak past.

* | | Use sockaddr instead of timeval in @cast testJosh Stone2009-04-292-11/+15
| | | | | | | | | | | | | | | | | | | | | | | | Using timeval had problems on big-endian multi-arch platforms (ppc64), because the user tv_sec used in the @cast didn't match the kernel tv_sec used to provide a pointer. Hopefully reading from a sockaddr should be more robust, as that type doesn't appear to need any compat wrappers for multi-archs.
