| * Correct block IO and IO scheduler tapset and test caseWenji Huang2009-11-232-4/+3
| | | | | | | | | | | | * tapset/ioblock.stp: Update comment and variables. * testsuite/buildok/ioblock_test.stp: Add parameters. * testsuite/buildok/ioscheduler.stp: Remove redundant parameters.
| * Added tracepoint-based probes to block IO and IO scheduler tapsets.Prerna Saxena2009-11-222-0/+20
| | | | | | | | | | Added testcases for these probes. Also, modified comments in ioblock.stp so that tapset docmentation can be automatically generated for this tapset.
| * PR 10981. Fixed buildok/netdev.stp for RHEL5.David Smith2009-11-181-2/+2
| | | | | | | | | | | | | | * tapset/networking.stp: Made 'netdev.change_rx_flag' and 'netdev.get_stats' optional, since those functions don't exist on RHEL5. * testsuite/buildok/netdev.stp: Ditto.
| * Don't kfail buildok/sched_test.stp and buildok/process_test.stp.David Smith2009-11-181-2/+0
| | | | | | | | | | | | * testsuite/systemtap.pass1-4/buildok.exp: On rhel5 and rawhide, the buildok/sched_test.stp and buildok/process_test.stp tests pass sucessfully, so there is no reason to kfail them.
| * PR 5150. Fixed nfs tapset by making probes optional.David Smith2009-11-181-1/+0
| | | | | | | | | | | | | | * tapset/nfs_proc.stp: Made 'nfs.proc.read', 'nfs.proc.write', and 'nfs.proc.commit' optional for newer kernels without those functions. * testsuite/systemtap.pass1-4/buildok.exp: Expect nfs-all-probes.stp to pass.

* | Ensure uprobes/Makefile never returns failure due to setting permissions.Dave Brolley2009-11-233-984/+675

* PR5916: Exploit kretprobe data storage areaJosh Stone2009-11-102-0/+74
| | | | | | | | | | | | | | | | | | | | Since 2.6.25, kretprobes can carry a data packet to be filled in an entry_handler. This patch lets us store our implicitly-saved $target variables in .return probes in that data area. * tapset/kretprobe.stp: New get/set functions for kretprobe data. * translate.cxx (c_unparser::emit_common_header): Add context->pi_longs. * tapsets.cxx (dwarf_var_expanding_visitor::visit_target_symbol_saved_return): Switch between the old and new methods of saving $vars in .return probes. (dwarf_var_expanding_visitor::gen_mapped_saved_return): The old way. (dwarf_var_expanding_visitor::gen_kretprobe_saved_return): The new way. (dwarf_derived_probe::join_group): Don't register paired entry-handlers. (dwarf_derived_probe::dwarf_derived_probe): Remember saved-var details. (dwarf_derived_probe_group::emit_module_decls): Output saved-var details. Also split the kretprobe handler whether we're on entry or return. (dwarf_derived_probe_group::emit_module_init): Prepare the entry handler. * testsuite/systemtap.base/kretprobe-vars.stp: Test implicit $var saving.

* Fix transok/tval-opt.stp testcase. Pick diffent function and non-empty block.Mark Wielaard2009-10-151-1/+2
| | | | | | | | | | | | This testcase succeeded just because the value being set couldn't be found. So the error message being compared was the same. Set -o pipefail to catch that case. On vta compiled kernels it failed because the optimizer turned { statement } into statement. So pick a function and argument which location can always be found and add an extra 'next' statement so the block isn't folded. * testsuite/transok/tval-opt.stp: Set -o pipefail. Add 'next' to make sure block isn't empty. Use "do_filp_open" and "mode".
