* Use || and && in preprocessor's conditions in tapsets.Przemyslaw Pawelczyk2009-08-281-13/+3

* Cleanup some deref handling in the task tapsetJosh Stone2009-08-261-11/+20
| | | | | | | | | | | | | Some of this is just cosmetic, but there is one big takeaway: there's a error-goto between kread calls and the CATCH_DEREF_FAULT. You must not allow this to bypass any resource management, like unlocking a resource that you grabbed! * tapset/task.stp (pid2task): No derefs, so remove the CATCH. (task_gid, task_egid, task_uid, task_euid): Move the CATCH within the #ifdef branch that actually needs it. (task_open_file_handles, task_max_file_handles): Ensure that we always call rcu_read_unlock if we locked it!

| * This SNMP group of tapsets provides probes used to count SNMP managementDavid J. Wilder2009-07-163-0/+968
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* Add str_replace() To TapsetsVarun Chandramohan2009-06-221-0/+33
| | | | | | | | | | | | | | | | | | This patch adds a search and replace string functionality to existing tapsets. The functionality is as follows: The function takes in a parent string and searches for a substring as specified by the user. If substring not found, the parent string is returned. If substring is found, it is replaced by another string and returned. NOTE: The function will search and replace all the occurrence of substrings in a parent string when matched.

* Fix target_set tapset.Przemyslaw Pawelczyk2009-06-181-10/+18
| | | | | | | | Revise acquiring of pid and ppid in fork.return probe -- use returnval() and pid() instead of pid() and ppid() respectively. Add pid removal on exit syscall. Use dwarfless syscall probe aliases. Correct formatting. Signed-off-by: Josh Stone <jistone@redhat.com>
* Fix tokenize function and test.Przemyslaw Pawelczyk2009-06-171-8/+15
| | | | | | | | | | | | | | | | | Previous implementation was error-prone, because allowed returning empty tokens (mimiced strsep()), which is fine if there is a NULL semantic. Unfortunately SystemTap doesn't provide it in scripts and has only blank string (""), therefore testing against it was misleading. The solution is to return only non-empty tokens (mimic strtok()). * tapset/string.stp: Fix tokenize. * testsuite/systemtap.string/tokenize.stp: Improve and add case with more than one delimiter in the delim string. * testsuite/systemtap.string/tokenize.exp: Ditto. * stapfuncs.3stap.in: Update tokenize description. * doc/langref.tex: Ditto.

* Fix nd_syscalls.stp for architectures using SYSCALL_WRAPPERS.Przemyslaw Pawelczyk2009-05-261-305/+568
| | | | | | | | | | | | Add kprobe.function("SyS_*") probe points to nd_syscall.* probe aliases. Analogue of commit 132c337c with two exceptions: - remove sufficiency of these new probe points (use '?' instead of '!'), because translator always considers them resolved, - make non-SyS probe points optional in probe aliases affected by syscall wrappers, because otherwise they will fail on such architectures.

* Move the "pure" tag into the body of __is_user_regsJosh Stone2009-05-222-2/+4
| | | | | | The "/* pure */" tag has no effect unless it is within the embedded-C body of a function. In this instance, they were accidentally moved out during the syscall cleanups.
* Use embedded-C for empty functionsJosh Stone2009-05-223-12/+6
| | | | | | | | | | The functions asmlinkage() and fastcall() are used to help access syscall parameters on i686. All other archs don't need this, but they still define empty functions to shield the callers from arch details. However, stap issues warnings for empty script-level functions. This patch changes them to "%{ /* pure */ %}" so there's no complaint, and they will still get optimized away.

* PR10177: init/kill time in sleepy context onlyJosh Stone2009-05-201-15/+2
| | | | | | | | | | | | 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.
