* Restore staprun's support for REAL_UID/GIDJosh Stone2009-05-221-1/+14
| | | | | This is needed for run-stap so that stapio and all child processes can run as the originally invoking user instead of root.

| * Fix gcc warning about Dwarf_Addr initialization.Mark Wielaard2009-05-211-1/+1
| | | | | | | | * translate.cxx (dump_unwindsyms): Initialize eh_frame to 0, not NULL.
| * PR10177: init/kill time in sleepy context onlyJosh Stone2009-05-205-44/+42
| | | | | | | | | | | | | | | | | | | | | | | | 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.
| * Properly read eh_frame and pass is_ehframe correctly.Mark Wielaard2009-05-202-8/+12
| | | | | | | | | | | | | | | | | | * runtime/unwind.c (adjustStartLoc): Add extra dbug_unwind. (_stp_search_unwind_hdr): Always pass true for is_ehframe. (unwind_frame): Properly pass through is_ehframe to adjustStartLoc(). (unwind): Add extra dbug_unwind. * translate.cxx (dump_unwindsyms): Output and use correct eh_frame and eh_len.
| * Use debug_frame table, then fallback to eh_frame when necessary.Mark Wielaard2009-05-201-24/+39
| | | | | | | | | | | | | | * runtime/unwind.c (unwind): Call new unwind_frame() first with debug_frame data, then if that wasn't able to unwind again with eh_frame data. (unwind_frame): Adapted version of old unwind() function that takes a table, table length and whether it is an eh_frame table.
| * Pass and use ptrType and is_ehframe to unwind adjustStartLoc.Mark Wielaard2009-05-201-53/+66
| | | | | | | | | | | | | | * runtime/unwind.c (adjustStartLoc): Add ptrType and is_ehframe as arguments. Use these to adjust location when necessary. (DEBUG_UNWIND): Move block before adjustStartLoc. Pass false for is_ehframe throughout.
| * Fetch and store both debug_frame and eh_frame tables.Mark Wielaard2009-05-204-58/+113
| | | | | | | | | | | | | | | | | | | | | | | | | | * runtime/sym.h (_stp_module): Remove unwind_data, unwind_data_len and unwind_is_ehframe fields. Add debug_frame, eh_frame, debug_frame_len, eh_frame_len and eh_frame_addr fields. * runtime/unwind.c: Use debug_frame and debug_frame_len instead of unwind_data and unwind_data_len throughout. (cie_for_fde): Take unwind_data and is_ehframe as direct arguments. * runtime/unwind/unwind.h (cie_for_fde): New function declaration. * translate.cxx (get_unwind_data): Fetch and return both debug_frame and eh_frame tables. (dump_unwindsyms): Dump both debug_frame and eh_frame tables.

* Fix alignment of probe aliases in syscalls(|2).stp.Przemyslaw Pawelczyk2009-05-192-736/+736
| | | | | | | Align probe points in probe aliases to equal sign using spaces as it's already done in nd_syscalls.stp. Signed-off-by: Josh Stone <jistone@redhat.com>
* Unify formatting of syscalls.stp and syscalls2.stp.Przemyslaw Pawelczyk2009-05-192-1059/+1407
| | | | | | | | | | | | | | | Rules: - Specify probe points for aliases starting from the alias declaration line and with one probe point per line. - Use K&R indent style -- probe alias/point/function opening brace goes to the line following the declaration, other opening braces are kept on the same line as the control statements. - Indent using tabs. - Surround operators with spaces. - Put spaces after commas. - Avoid trailing whitespaces.

| | | | | | | | | | | | | | | | | | | | | | | | The method query_cu_containing_global_address was only called by query_cu_containing_module_address, and the latter was just doing a simple argument transform. They are now merged into a single method, query_cu_containing_address. The function module_address_to_global is also merged here at its only call site.

| | | | | | | | | | | | | | | | | | | | | | | | These three methods had no callers, and are thus obsolete: dwflpp::focus_on_module_containing_global_address(Dwarf_Addr a) dwflpp::global_address_to_module(Dwarf_Addr a) dwflpp::cu_name_matches(string pattern)
