* PR 9871 (partial) fix. Removed all embedded-C in rpc.stp.David Smith2010-04-071-94/+69
| | | | * tapset/rpc.stp: Replaced all embedded-C functions with script language.
* 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>
* Backport recently added probes to RHEL5(U5)Steve Dickson2010-03-161-1/+6
| | | | | | | | Ensured the recent additions of v4 probes and supporting routines worked or at least don't break with RHEL5 U5 kernels (this time without kernel version checks). Signed-off-by: Steve Dickson <steved@redhat.com>

* Allow better filtering with IP address and File handleSteve Dickson2010-03-161-0/+24
| | | | | | | | | | | | | | | 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>
* PR9932: use @cast module search pathJosh Stone2009-03-101-27/+14
| | | | | | | | | The nfs, rpc, and scsi tapsets use @cast on types that may be compiled into a kernel module or into the main kernel binary. The @cast search path separated with colons lets us search both the kernel and the module. For a couple of cases, I also merged sequential @casts that work just fine as a single cast with a multiple-level dereference.
* PR9871: use @cast in tapsetWenji Huang2009-03-061-52/+42
