* 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.
* Make the stap-prep script available in the RPM.William Cohen2010-03-122-0/+4

* Add startswith/endswith helpersJosh Stone2010-03-118-26/+40
| | | | | Inspired by the Python equivalents, these new utility functions just make it a little cleaner to match at the beginning or end of a string.
* 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.
* Fix proc_mem.stp for RHEL5.David Smith2010-03-111-1/+1
| | | | | * tapset/proc_mem.stp: Move header file so that it will compile on RHEL5 systems.
* Revoke unprivileged from ftrace()Josh Stone2010-03-111-4/+2
| | | | | | | | It's writing into a system-wide resource, so it shouldn't be permitted to just anyone. Also remove the printk fallback that isn't actually functional. * tapset/logging.stp (ftrace): Remove unprivileged and printk.
* Update tapset proc_mem for 2.6.34Wenji Huang2010-03-111-0/+32
| | | | | * tapset/proc_mem.stp(_stp_get_mm_counter_file_rss, _stp_get_mm_counter_anon_rss): Use embedded function.
* 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.
* Revert "Remove unnecessary embedded-c function __dentry_get_current_root()."Mark Wielaard2010-03-101-1/+15

* Be pessimistic about the gcc version as debuginfo has an undependable case ↵Stan Cox2010-03-102-2/+2
| | | | | | (RH572260). * sdt.h (GNUC_VERSION): Check against gcc 4.5.0
* PR 11210 move stapprobe.* man pages to tapset::*William Cohen2010-03-102-23/+9
| | | | | | make on RHEL-5 and earlier cannot deal with the :: in the man page names. This work around uses the install-data-local rule to install the manpages to avoid confusing the older versions of make.
* Removed unneeded '-u' switch from 3 tests.David Smith2010-03-103-3/+3
| | | | | | | * testsuite/buildok/scheduler-test-tracepoints.stp: Removed unneeded '-u' option. * testsuite/buildok/vm.tracepoints.kmalloc.stp: Ditto. * testsuite/buildok/vm.tracepoints.stp: Ditto.

* PR11366 Always call semantic_pass_const_fold.Mark Wielaard2010-03-101-2/+3
| | | | | | | | | Even in unoptimized mode we want constant folding to work to make sure non-existing $variable expressions (detected through @defined) aren't included. * elaborate.cxx (semantic_pass_optimize1): Call semantic_pass_const_fold() unconditionally.
* Remove unnecessary embedded-c function __dentry_get_current_root().Mark Wielaard2010-03-101-15/+1
| | | | | * tapset/dentry.stp: Removed embedded-c include and function __dentry_get_current_root(). Use task_current and @cast in d_path().
* tapset/task.stp remove redundant extra @defined in task_cpu().Mark Wielaard2010-03-101-2/+2

* PR 11210 move stapprobe.* man pages to tapset::*William Cohen2010-03-0919-119/+68
| | | | | Complete the renaming scheme with prefix of "tapset::" for the man pages related to over all description of groups of probes.
* PR11360: Make @defined and -L play niceJosh Stone2010-03-092-9/+35
| | | | | | | | | | | | | The constant-folding is now enabled for s.listing_mode_vars, despite all other optimizations being disabled. This is needed so we can prune any invalid branches that are gated by @defined. * elaborate.cxx (semantic_pass): Leave the optimization decision to the optimization passes themselves. (semantic_pass_optimize1): Predicate most optimizations, but enable the constant-folding for listing_mode_vars too. (semantic_pass_optimize2): Predicate all (1) optimizations. * testsuite/semok/defined_list_vars.stp: New test.
* Include __GNUC_RH_RELEASE__ in the volatile check.Stan Cox2010-03-092-4/+7
| | | | sdt.h (GNUC_VERSION) Include __GNUC_RH_RELEASE__. Check for at least gcc 4.4.4
* PR 11338 (partial): Used '@defined()' in task, dentry, and scsi tapsets.David Smith2010-03-093-20/+13
| | | | | | * tapset/task.stp: Used '@defined()' to remove kernel version checks. * tapset/dentry.stp: Ditto. * tapset/scsi.stp: Ditto.
* Update tests to check for uprobes instead of utrace.David Smith2010-03-093-16/+17
| | | | | | | * testsuite/systemtap.context/uprobe_stmt_num.exp: Change utrace test to uprobes test. * testsuite/systemtap.context/uprobe_uaddr.exp: Ditto. * testsuite/systemtap.base/bz5274.exp: Ditto.

| | | | | | | | * initscript/logrotate.stap-server: Add logrotate config file to make sure stap-server logfile doesn't grow too large. * systemtap.spec: Install logrotate config file. Also follow <https://fedoraproject.org/wiki/PackagingDrafts/Logfiles> to correctly create the logfile.
* Improved PR 11309 by fixing directory and file permissions.David Smith2010-03-091-2/+3
| | | | | * systemtap.spec: Fixed directory and file permissions on /usr/share/systemtap/runtime/uprobes and /var/log/stap-server.
* PR 11210 Eliminate man page collisionsWilliam Cohen2010-03-091-4/+4
| | | | | | | The various man pages for each systemtap probe and function are prepended with "probe::" and "function::" respectively to avoid collisions with other man3 pages with the same name. For example systemtap's strlen function was colliding with glibc's strlen function.
* Only use volatile for sdt.h arguments when needed.Stan Cox2010-03-091-55/+61
| | | | | sdt.h (VOLATILE_ARG): gcc 4.4.3 support for inline asm argument debug info means volatile is not needed.
* build: re-enable librpm checkingFrank Ch. Eigler2010-03-083-6/+19
| | | | | | * configure.ac: With AC_CHECK_LIB()'s four-parameter variant, the default AC_DEFINE etc. is removed, so restore the key parts by hand.
