* security: list some prudent security practices for stap-serverFrank Ch. Eigler2010-01-191-0/+23
|
* Swap DW_OP_shr and DW_OP_shra.Roland McGrath2010-01-191-2/+2
| | | | * loc2c.c (translate): DW_OP_shr is unsigned, DW_OP_shra is signed.
* Use signed division for DW_OP_div.Roland McGrath2010-01-191-1/+10
| | | | * loc2c.c (translate): Use signed division for DW_OP_div.
* Fix the listing mode of process.library.markJosh Stone2010-01-181-1/+1
| | | | | | | | | Our hack for producing nicer listing modes was to write the mark name in component index 1. That's fine for process.mark, but writes the wrong position for process.library.mark. It now munges the last probe component of any number of indexes. (A better fix is due in PR10831, preserving the derivation chain.)
* PR11173 Markers get a bad address in prelinked libraries.Mark Wielaard2010-01-183-43/+9
| | | | | | | | | | | | | Our literal_addr_to_sym_addr() function was just wrong. To compensate for raw addresses read from elf (either given by the user or through a mark transformation) we need to know what the elf_bias is (as returned by dwfl_module_getelf) before feeding them to any libdwfl functions. * tapsets.cxx (query_module_dwarf): Always add elf_bias to raw function or statement addresses before calling query_addr(). (query_addr): Don't call literal_addr_to_sym_addr(). * dwflpp.h (literal_addr_to_sym_addr): Removed. * dwflpp.cxx (literal_addr_to_sym_addr): Likewise.
* PR11105: forget about packaging stap-server-requestFrank Ch. Eigler2010-01-151-1/+0

* Relax sdt address check for attach to running process case.Stan Cox2010-01-152-5/+10
| | | | * uprobes-common.c (stap_uprobe_change_plus): Relax VM_EXEC check.
* PR11105: support default unset --prefixFrank Ch. Eigler2010-01-152-3/+8
| | | | * configure.ac (STAP_PREFIX): Map NONE -> /usr/local.
* PR11105: remove extraneous \n from localized foo.stp script file nameFrank Ch. Eigler2010-01-151-1/+1

* testsuite: fix wording of invalid-entry test groupFrank Ch. Eigler2010-01-151-2/+2

* PR11105: Remove stap-server-request shell script.Frank Ch. Eigler2010-01-153-514/+2
| | | | * Makefile.am: Don't install it any more.
* PR11105: robustify stap-serverFrank Ch. Eigler2010-01-153-100/+415
| | | | | | | | | | | * main.cxx (main): Always downgrade client-provided -p5 to -p4. * stap-client (unpack_response): Sanitize stdout due to same. * stap-server-connect.c: Eliminate a bunch of globals. (handle_connection): Make things locals instead. Base tmp files on $TMPDIR. (spawn_and_wait): New helper function. (handleRequest): New monster function to inline rest of old stap-server-request.
* server: log controlling pidFrank Ch. Eigler2010-01-151-0/+2
| | | | * stap-serverd (initialization): Log startup pid.
* runtime: better staprun diagnostics for failed signature testsFrank Ch. Eigler2010-01-151-2/+8
| | | | * modverify.c (verify_module): Print some messages for verbose > 1.
* PR11105: stap-client wire protocol changeDave Brolley2010-01-151-114/+99

* Improve stack printing formatWenji Huang2010-01-151-1/+2
| | | | * runtime/stack.c (_stp_stack_print_tsk): Use _stp_symbol_print.
* PR11151: Recover stap_uprobes slots on process exitJosh Stone2010-01-143-0/+17
| | | | | | | | | | When a process exits, it won't necessarily bother to munmap all of its shared libraries. This patch makes sure that with uprobes in libraries, we still grab an exit notification and clear everything out. * runtime/uprobes-common.c (stap_uprobe_process_munmap): New. * tapsets.cxx (uprobe_derived_probe_group::emit_module_decls): Use above callback so that we can recover our resources on process exit.
* Allow / as a random argyment character when fuzzing.Dave Brolley2010-01-141-1/+1
|
* PR10467 cont'd: be tolerant of bad line numbersJosh Stone2010-01-141-5/+2
| | | | | | | | | If a line number is invalid for a source file, that should not be a fatal error, as it may still be valid for some other matching source file. * dwflpp.cxx (dwflpp::iterate_over_srcfile_lines): Don't assert that the line must be found, just break out quietly.
* Fixed rawhide syscall testsuite problem.David Smith2010-01-141-2/+2
| | | | | * testsuite/systemtap.syscall/net1.c (main): The 'bzero()' function has been deprecated on rawhide. Replaced with 'memset()'.

* Fix rawhide compile problem.David Smith2010-01-141-1/+1
| | | | | * main.cxx (getmemusage): On rawhide systems, 'getpagesize()' has been deprecated. Substitute 'sysconf(_SC_PAGESIZE)'.
