| | | | * testsuite/systemtap.base/set_kernel.stp: try/catch addresses of -1.
* Test that all of the set_kernel_* functions workJosh Stone2010-04-013-0/+107
| | | | | * testsuite/buildok/set_kernel.stp: Test that all can build. * testsuite/systemtap.base/set_kernel.stp: Test that values are all set.
* PR9958: Test that the guru notation is workingJosh Stone2010-04-012-0/+8
| | | | | * testsuite/semko/gurufunc.stp: Test rejection without -g. * testsuite/semok/gurufunc.stp: Test acceptance with -g.
* Add kernel-writing functions for guru onlyJosh Stone2010-04-012-0/+128
| | | | | * runtime/loc2c-runtime.h (store_deref_string): New. * tapset/conversions-guru.stp (set_kernel_*): New guru functions.
* PR9958: Let embedded-C assert guru modeJosh Stone2010-04-011-0/+5
| | | | | * staptree.cxx (varuse_collecting_visitor::visit_embeddedcode): Don't allow calling /* guru */ functions unless guru mode is active.
* Make sure that the testsuite can find its serverJosh Stone2010-03-311-0/+7
| | | | | * testsuite/lib/systemtap.exp (setup_server): Use stap-find-servers to check that the firewall is letting us through to the server.
* Use a different PATH approach for pfilesJosh Stone2010-03-311-5/+2
| | | | | | | //bin/true && exec stap -g $0 ${1+"$@"} This keeps it as an entirely valid stap script, so manual stap invocation still works (as in pfiles.meta).
* Use a wider cache for simple function lookupsJosh Stone2010-03-303-3/+126
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When we have many individual function lookups, like the nearly 1000 with syscall.*, each one will iterate every CU in the module (M) and then do a cache lookup in N entries. That's a thousand MlogN lookups. We can instead keep the functions in a module-wide map, and then the complexity is just a thousand logMN lookups. Before: $ ./run-stap -l 'syscall.**' --vp 01 >/dev/null Pass 2: analyzed script: 793 probe(s), 11 function(s), 20 embed(s), 0 global(s) using 245872virt/147304res/78272shr kb, in 1390usr/60sys/1448real ms. After: $ ./run-stap -l 'syscall.**' --vp 01 >/dev/null Pass 2: analyzed script: 793 probe(s), 11 function(s), 20 embed(s), 0 global(s) using 246228virt/147616res/78276shr kb, in 720usr/60sys/782real ms. * dwflpp.cxx (dwflpp::iterate_single_function): Do a simple function lookup based on a module-wide cache. (dwflpp::mod_function_caching_callback): Helper for above. * tapsets.cxx (dwarf_query::query_module_functions): Query a single function from the module-wide cache. (dwarf_query::query_module_dwarf): Use above for simple cases.
* Remove unused code from iterate_over_functionsJosh Stone2010-03-303-14/+3
| | | | | | * dwflpp.cxx (dwflpp::iterate_over_functions): No caller is using has_statement_num anymore (since 6b517475), so kill it. * tapsets.cxx (query_cu): Let the default call rule the day.
* PR 9871 (partial) fix. Removed some embedded-C in ioblock.stp/vfs.stp.David Smith2010-03-304-29/+42
| | | | | | | | | * tapset/dev.stp: Added a bdevname() script function. * tapset/ioblock.stp: Rewrote the embedded-C devname function to just use bdevname() script function. * tapset/vfs.stp: Removed embedded-C __bdevname() C function. Calls bdevname() script function instead. * tapset/string.stp: Added isdigit() function.
* testsuite: convert pfiles.stp to $PATH-based stap invocation formFrank Ch. Eigler2010-03-301-1/+7

* Add kprobe user probe semaphore handling.Stan Cox2010-03-262-25/+198
| | | | | | | | | | | | | | | | | | | | | | Adds stap_kprobe_process_found and stap_kprobe_mmap_found handlers and then the task_finder uses those to set the semaphore values. The probe adds user_path and user_lib which are used by the task_finder to decide what object to sniff. * sdt.h (STAP_SEMAPHORE): Also define for kprobes. * tapsets.cxx (dwarf_derived_probe): Add user_path and user_lib. (dwarf_derived_probe::join_group): Enable task finder for kprobes. (dwarf_derived_probe::dwarf_derived_probe): Set user_path and user_lib. (dwarf_derived_probe_group::emit_module_decls): Emit stap_kprobe_mmap_found, sdt_sem_offset, sdt_sem_address, pathname, and finder declarations.

(dwarf_builder::build): Set user_path and user_lib. (kprobe_derived_probe): Add path and library. (kprobe_builder::build): Get process and library params
* PR 11338 (partial): Used '@defined()' in inet_sock tapsets.David Smith2010-03-261-21/+7
| | | | | | * tapset/inet_sock.stp (inet_get_local_port): Used '@defined' instead of a kernel version check. Added RHEL4 support. (inet_get_ip_source): Now calls __ip_sock_daddr() to get daddr.
* PR 9871/11338 fix in tcpmib.stp by removing embedded-C and using @defined.David Smith2010-03-263-88/+69
| | | | | | | | | | | | | | | | * tapset/tcpmib.stp (tcpmib_get_state): Changed from embedded-C to script code. (tcpmib_local_addr): Instead of an embedded-C function, now calls function from ip.stp/tcp.stp. (tcpmib_remote_addr): Ditto. (tcpmib_local_port): Ditto. (tcpmib_remote_port): Ditto. (tcpmib.OutRsts.A): Used '@defined' instead of a kernel version check. * tapset/ip.stp (__ip_sock_saddr): Used '@defined' instead of a kernel version check. Added RHEL4 support. (__ip_sock_daddr): Ditto. * tapset/tcp.stp (__tcp_sock_dport): Ditto. (__tcp_sock_sport): Ditto.
* Remove probe_point code duplicationJosh Stone2010-03-251-14/+1
| | | | * staptree.cxx (probe_point::str): Don't duplicate ::print -- reuse it.
* Print probepoint addresses in hexJosh Stone2010-03-253-30/+38
| | | | | | | | | | * staptree.h (literal_number): Add a bool "print_hex". * staptree.cxx (literal_number::print): Switch to hex if needed. * tapsets.cxx (dwarf_derived_probe::dwarf_derived_probe): Write the statement number component with a hex literal_number. (sdt_query::convert_location): Ditto (kprobe_derived_probe::kprobe_derived_probe): Ditto. (hwbkpt_derived_probe::hwbkpt_derived_probe): Ditto for data addr.

* PR11399: Allow '**' to match tapsets across '.'Josh Stone2010-03-253-0/+83
| | | | | | | | | | | | | | Normally wildcards are constrained to matching a single probe point component between the '.' separator. This patch enables '**' to match across the separator. Probe point parameters are still absolute separators though, as there's not really a meaningful semantic we could use to cross them with '**'. * elaborate.cxx (isdoubleglob): Check for '**'. (match_node::find_and_build): Recurse '**' to cross separators. * testsuite/semok/doubleglob.stp: New test of broad wildcards. * testsuite/semko/doubleglob.stp: New negative test.
* PR11427: port sdt.h to sparcTom Callaway2010-03-241-1/+1

* Small cleanup of context.exp.David Smith2010-03-241-15/+18
| | | | | * testsuite/systemtap.context/context.exp: Used "make -C $build_dir" to avoid using 'cd'. Added error handling.

| | | | | | | | * testsuite/systemtap.base/atomic.exp: Removed the need for the external module by putting the atomic_long_t inside the stap module. * testsuite/systemtap.base/atomic_module.c: Removed. * testsuite/systemtap.base/atomic_module.makefile: Ditto. * testsuite/lib/stap_run_error.exp (stap_run_error): Better error handling.
* Fix pipe syscall name in return probe.Mark Wielaard2010-03-241-1/+5
| | | | | * tapset/syscalls2.stp (syscall.pipe.return): If @defined($flags) then use it to determine correct name.
* Removed unneeded convenience variables in syscall.pipe.return.David Smith2010-03-231-5/+1
| | | | | * tapset/syscalls2.stp: Removed unneeded 'flags' and 'flag_str' convenience variables in syscall.pipe.return probe.

| | | | | * tapset/x86_64/nd_syscalls.stp: Made 'sys32_mmap2' probe point optional, since it doesn't exist on newer kernels.
* Fixed cut-and-paste error for sys_ia64_pipe.David Smith2010-03-221-1/+1
| | | | | * tapset/nd_syscalls2.stp: Removed '.call' from 'kprobe.function("sys_ia64_pipe")'.
* Ifdef out atomic_long_read() body on older kernels where the type doesn't exist.David Smith2010-03-221-0/+2
| | | | | * tapset/atomic.stp: If we don't have ATOMIC_LOGN_INIT(), ifdef out the function.
