* PR10427 Multiple tracepoints OK!Mark Wielaard2009-07-221-1/+3
| | | | | * testsuite/systemtap.base/tracepoints.stp: Only print once, when enough hits, or at the begin probe.
* Use the query paradigm for resolving sdt probesJosh Stone2009-07-212-377/+384
| | | | | | | | | | | | | | | | There was a bad assumption in the probe_table initialization that the dwflpp->module would be immediately valid. We should not assume that dwflpp only has one module, or that any module is necessarily in focus. Instead, I've created an sdt_query class which will call an iterate_over_modules like the other dwarf probe types. For now this means just a single module, but it will also open the door to iterating over all linked libraries too, for example. * dwflpp.cxx (dwflpp::setup_user): don't "save mod!" anymore * tapsets.cxx (probe_table -> sdt_query): convert to a query-style class, and also take over the task of iterating over the probes. (dwarf_builder::build): leave the iteration to sdt_query
* Remove unused 'sess' from dwarf_query ctorJosh Stone2009-07-211-6/+4

* PR10182 systemtap.spec should try to clean up old leftover uprobes module.Mark Wielaard2009-07-211-0/+2
| | | | systemtap.spec (post,preun): Call rmmod uprobes.
* Save module when dwflpp setup_user.Mark Wielaard2009-07-211-0/+1
| | | | * dwflpp.cxx (setup_user): Set module to mod.
* PR10424: Consider each tracepoint header separatelyJosh Stone2009-07-205-52/+83
| | | | | | | | | | | | | | | | With the current monolithic tracepoint query module, a failure in any of the discovered tracepoint headers means that you can't use any of the others either. This patch creates a separate query module for each header so they can pass or fail independently. * buildrun.cxx (make_tracequery): take a single header name instead of globbing for everything we can find. * hash.cxx (find_tracequery_hash): name the header file we're hashing. * tapsets.cxx (tracepoint_query::handle_query_func): make sure we don't duplicate tracepoints found through different headers. (tracepoint_builder::get_tracequery_module): get a header's module (tracepoint_builder::init_dw): glob for all tracepoint headers, and feed all their modules into dwflpp.
* Make sure that non-existent files still affect hashingJosh Stone2009-07-201-6/+6
| | | | | | | The fact that a file _doesn't_ exist is significant, so adding such a file to a computed hash should still influence the output. * hash.cxx (hash::add_file): add bogus stat info for non-existent files
* Allow dwflpp to take a vector of module namesJosh Stone2009-07-202-21/+38
| | | | | | | | | This will be used to load tracepoint modules as a bunch of little query modules into a single dwflpp. * dwflpp.cxx (setup_user): take a vector instead of a single module (dwflpp::dwflpp): form a vector in the singular case, and add a variant that takes and passes through a vector of modules.
* Return hash module values directly as stringsJosh Stone2009-07-204-20/+19
| | | | | | | | * session.h (systemtap_session): remove tracequery_path * hash.cxx (find_tracequery_hash, find_typequery_hash): return strings * tapsets.cxx (dwarf_cast_expanding_visitor::filter_special_modules): get the hashed path from the return value instead of a parameter (tracepoint_builder::init_dw): ditto, and don't stuff it in session
* Fixes for 2.6.31. There are some changes in sk_buff structure those causeDavid J. Wilder2009-07-202-10/+81
| | | | | failures of compiling ipmib.stp and tcpmib.stp, rtable and dst fields are deleted.
* Fixed PR 10386 by removing the need to convert a pid to a task.David Smith2009-07-204-18/+6
| | | | | | | | | * runtime/itrace.c (usr_itrace_init): Changed prototype to take a task_struct instead of a pid. * tapset-itrace.cxx (emit_module_decls): Updated usr_itrace_init() call. * runtime/autoconf-find-task-pid.c: Removed, since only user_itrace_init() was using it. * buildrun.cxx (compile_pass): Removed autoconf-find-task-pid.c test.
* * tapsets.cxx (dwarf_builder::probe_table::convert_probe):Stan Cox2009-07-202-59/+54
| | | | | | First check kprobe and utrace (did we arrive via stap?) then check if probe arg matches mark("NAME") * sdt.h (STAP_PROBE?_): Use STAP_GUARD for stap check, not gettid.

* This SNMP group of tapsets provides probes used to count SNMP managementDavid J. Wilder2009-07-1611-1/+1805
| | | | | | | | | | | | | | | | | | | events. The probes mirror many of the SNMP statistics defined in /usr/include/linux/snmp.h. Each probe represents a single SNMP statistic or MIB. Each of the probe's handler is called when system performs an operation that would alter the associated statistic. Along with each probe is defined an indexed set of counters used to record probe hits. The probe handlers call a user supplied callback functions to determine which counter to alter. The user's callback should returns a key value that will be used to index the counter. For example a callback could return a unique value for each socket. This would results in a separate counter being used for each socket. tcpipstat.stp shows how snmp tapsets could be used. Tcpipstat collects and displays network statistics related to individual TCP sockets or groups of sockets. The statistics that are collected are simmer to that of the command netstat -s, only sorted and grouped by individual sockets. Signed-off-by: David Wilder <dwilder@us.ibm.com>
