* 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>
* Update the nfsd buildok test suite probesSteve Dickson2010-03-161-1/+0
| | | | | | | The __get_fh() is no longer exists due to the use of the @cast defines, so its removed 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>

* Get d_path's root natively with @castJosh Stone2010-03-122-15/+9
| | | | | | | | | | | As mjw's aborted commit 5ab0b1b6 attempted, we can use a @cast to get the filesystem root for the current task instead of embedded-C. I've left it using the kernel debuginfo instead of headers for now, because all of the neighboring @casts are doing the same. * tapset/dentry.stp (d_path): Use @cast to get the root. (__dentry_get_current_root): Remove, no longer needed. * testsuite/buildok/dentry.stp: Test that dentry's functions all build.

* Add startswith/endswith helpersJosh Stone2010-03-118-26/+40

* Fix the edge-case of MAXTRYLOCK=0Josh Stone2010-03-112-14/+24
| | | | | | | | | | | | | | | | | We didn't really have good semantics for what is meant by MAXTRYLOCK=0, so when skipped.exp tried it, we ended up locking the variable and then reporting a skip without ever unlocking it. This is now cleaning up the semantics such that MAXTRYLOCK defines how many times we should loop if the lock is busy. Thus MAXTRYLOCK=0 means we try only once and fail immediately. The testcase was accidentally creating contention due to the broken unlock behavior. We now have to try a bit harder to create real contention, so some lengthy delays are inserted to hoard the lock. * runtime/probe_lock.h (stp_probe_lock): Fix the skip behavior. * testsuite/systemtap.base/skipped.exp: Add a big udelay.

* PR11370: Add multi-header @castsJosh Stone2010-03-104-19/+39
| | | | | | | | | | Sometimes you need multiple headers to fully describe a type, so we now permit them to be listed together, e.g. "kernel<foo.h><bar.h>". * buildrun.cxx (make_typequery): Split the input string into a vector. (make_typequery_kmod, make_typequery_umod): Use the vector of headers. * testsuite/semok/cast.stp: Add a multi-header case. * stap.1.in, NEWS: Document it.
