* PR11402 Support pipe2 syscall.Mark Wielaard2010-03-192-0/+59
| | | | | | | | | The pipe2() was added to Linux in version 2.6.27.

* Make pipe file descriptors available in syscall.pipe[.return].Mark Wielaard2010-03-191-1/+34
| | | | | | | | | | | The actual value of the pipe file descriptors can be interesting, especially in the syscall.pipe.return probe. This can be done without any embedded C now using @cast. So don't use _fildes_u() anymore. _fildes_u in aux_syscall.stp is still retained because it is used in nd_syscalls2.stp for pipe. * tapset/syscalls2.stp (syscall.pipe, syscall.pipe.return): Add pipe1 pipe2 convenience variables. Don't use _fildes_u for argstr anymore.
* Use @defined() in syscall.pipe to select whether fildes_uaddr is available.Mark Wielaard2010-03-191-20/+10
| | | | | | * tapset/aux_syscalls.stp (syscall.pipe): Remove architecture dependent probe definitions. Newer gcc make $fildes available on more arches. Use @defined($fildes) to select on which ones.
* PR909: add perf.hw_cache.* aliasesFrank Ch. Eigler2010-03-181-0/+48
| | | | | | * tapset/perf.stp: Add 'em. * man/tapset::perf.3stap: Document 'em a little. * stapprobes.3stap.in: Fix .sample (not .samples) probe point typo.
* Fixed BZ 568032 by adding support for sys_ia64_pipe.David Smith2010-03-181-2/+9

| | | | | | * tapset/perf.stp: New file. * tapset-perfmon.cxx (perf_derived_probe): Drop event_name field throughout. Listen to type(N).config(M) instead.
* Fixed PR 11372 by removing (most) embedded-C from proc_mem.stp.David Smith2010-03-162-135/+169
| | | | | | | | | * tapset/proc_mem.stp: Tried to remove as much embedded-C as possible. * tapset/atomic.stp: New file. * testsuite/buildok/atomic.stp: New file. * testsuite/systemtap.base/atomic.exp: Ditto. * testsuite/systemtap.base/atomic_module.c: Ditto. * testsuite/systemtap.base/atomic_module.makefile: Ditto.
* The rpc buildok test suite probe breaks with new kernelsSteve Dickson2010-03-161-2/+21
| | | | | | | | | | | With newer kernels the rpc_release_task() routine is not defined because it becomes inline since its only called once. Plus the task allocation routines have changed so the arguments no longer match up with previous routines. So this patch uses the kernel_v clauses to allow the original functionality with older kernels and not to break on new kernels. Signed-off-by: Steve Dickson <steved@redhat.com>

* Allow better filtering with IP address and File handleSteve Dickson2010-03-162-23/+122
| | | | | | | | | | | | | | | To allow filtering by the client's IP address, the addr_from_rqst_str() function was added which extracts the IP address from incoming procedures and converts them into a character string. Calls to addr_from_rqst_str() were added to the top of each probe so callers of the probes can use the IP addresses as a filter. Calls to __svc_fh() were also sprinkled were needed so callers can also filter on file handles Signed-off-by: Steve Dickson <steved@redhat.com>
