* Fix configure on systems without 'gcc -fgnu89-inline' support (rhel4).David Smith2009-09-232-2/+59
| | | | | | * configure.ac: Only compile elfutils with '-fgnu89-inline' if the compiler actually supports it. * configure: Regenerated.
* Forward-ported staplog.c crash support (PR 10644).David Smith2009-09-233-62/+122
| | | | | | | | | | | | | | * staplog.c (get_rchan): Separated original relayfs code and current relayfs code. (get_rchan_buf): Ditto. (output_cpu_logs): Ditto. (get_rchan_addr): Handles original relayfs code detection. (setup_global_data): Looks for '_stp_relay_data' structure instead of '_stp_utt' structure. (open_output_file): Improved error message. * runtime/transport/relay_v2.c: Rearranged struct _stp_relay_data_type to make things a bit easier for staplog.c. * runtime/transport/relayfs.c: Ditto

* Use less idle time in testsuite.Mark Wielaard2009-09-198-27/+30
| | | | | | | | | | | | | | | | A lot of tests wait, sleep or use a timer for multiple seconds when that is not necessary. Reduce the time waited so save test time. * testsuite/systemtap.base/backtrace.stp: Exit after 100ms. * testsuite/systemtap.base/badkprobe.exp: Likewise. * testsuite/systemtap.base/global_end.stp: Likewise. * testsuite/systemtap.base/itrace.exp: Wait 1 sec instead of 5 for each test. * testsuite/systemtap.base/maxactive.exp: Likewise. * testsuite/systemtap.base/onoffprobe.exp: Match and use modname, so build script can be cached. * testsuite/systemtap.base/onoffprobe.stp: Wait miliseconds instead of seconds in each alias. Output module_name. * testsuite/systemtap.base/poll_map.stp: Start after 100ms.
* Fix uninitialized line numbers in the function specJosh Stone2009-09-181-1/+4
| | | | | | | | | The rewrite of parse_function_spec left the line numbers uninitialized when not used, but elsewhere was depending on that. Fix the uninit, and also don't depend on it. * tapsets.cxx (dwarf_query::parse_function_spec): Init line stuff. (query_cu): Branch on the spec_type, not the line contents.
* PR10655 part 1: uprobes: track sdt semaphores properlyFrank Ch. Eigler2009-09-183-37/+52
| | | | | | | | | | | | | | | | | | | commit 6846cfc8 introduced an unintended side-effect where semaphore tracking was identified with stap_uprobe_specs[] elements, which are normally static/const. This kernel patch <http://article.gmane.org/gmane.linux.kernel/854187> catches and panics on this. The cure is to move the variable over to the stap_uprobes[] array. * tapsets.cxx (uprobe emit_module_decls): Add sdt_sem_address to stap_uprobe{} struct, to contain per-process relocated semaphore address. (emit_module_decls,_init): Remove tsk field, restore constness of appropriate locals. Activate uprobe semaphore right around uprobe activation time. Remove semaphore clearing upon process exit, since by then it's gone. (emit_module_exit): Use remembered relocated semaphore address to clean up. Fix "-uprobe" DEBUG_UPROBES message. * runtime.h: #include <linux/sched.h>. * dtrace.in (*_semaphore): Make it an unsigned short - intended 16 bits on all common architectures/multilibs.

| | | | | | | | | | | | | | | | | | Allocated section needs to be writable when creating pic shared objects because we store relocatable addresses in them. We used to make this read only for non-pic executables, but the new semaphore support relies on having a writable .probes section to put the enabled variables in. * includes/sys/sdt.h (ALLOCSEC): Define unconditionally as "aw".

* Ensure that STAP_PROBE behaves like a single statementJosh Stone2009-09-171-43/+22
| | | | | | | | | | It's important for macros like this to appear as a single statement, so they won't break the control flow of the caller. The new STAP_SEMAPHORE macro was breaking this masquerade, but now I've moved it inside of the do-while block. * includes/sys/sdt.h (STAP_SEMAPHORE): Define the disabled case empty. (STAP_PROBE[1-10]_): Move the semaphore inside the do-while block.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The decrement can happen at the same time that the utrace detach is called. However, I'm concerned that this code isn't correctly handling the case where multiple tasks may register the same probe, so for now I've noted those places. I think task finder may have to help in fixing this... * tapset-utrace.cxx (utrace_derived_probe_group::emit_module_init): As noted in uprobes-land, there's no need to tear down anything. (utrace_derived_probe_group::emit_module_exit): Unify the detach and semaphore decrement, and note a concern about multiple tasks. (utrace_derived_probe_group::emit_module_decls): Note same concern. * tapsets.cxx (uprobe_derived_probe_group::emit_module_decls): Ditto. (uprobe_derived_probe_group::emit_module_exit): Ditto.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | Each probe needs to know the associated semaphore address, rather than the other way around. * session.h (sdt_semaphore_addr): Reverse the key-value types. * tapsets.cxx (record_semaphore): Take an index to only record the semaphore for newly added results. (sdt_query::handle_query_module): Adjust accordingly. (uprobe_derived_probe_group::emit_module_decls): Now it's a simple map lookup for sdt_sem_address. * tapset-utrace.cxx (utrace_derived_probe_group::emit_probe_decl): Ditto.
