| | * Relax the -Wframe-larger-than checkJosh Stone2009-10-211-1/+3
| | | | | | | | | | | | | | | This is just a workaround for PR10821, and should be reverted when that bug is fixed.
| | * Ensure that DWARF keeps loc2c to a reasonable stack depthJosh Stone2009-10-211-0/+7
| | | | | | | | | | | | * dwflpp.cxx (dwflpp::express_as_string): Limit stack depth to 32.
| | * PR10750 cont'd: Build with -Wframe-larger-than=512Josh Stone2009-10-211-0/+3
| | | | | | | | | | | | | | | * buildrun.cxx (compile_pass): Add the warning to limit the frame size even lower than the Kbuild default (only works for gcc 4.4+).
| | * PR10750: Enforce a reasonable limit on # of varargsJosh Stone2009-10-213-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we leave the number of args unbounded, then an excessively-sized printf could cause a kernel stack overflow. I've arbitrarily chosen 32 as our new maximum. * translate.cxx (c_unparser::visit_print_format): Throw if >32 args. * testsuite/transko/varargs.stp: Assert that 33 args aren't allowed. * testsuite/transok/varargs.stp: Assert that 32 args are ok.
| * | Kill off child processes correctly on exit.Tim Moore2009-10-271-30/+100
| | | | | | | | | | | | | | | | | | * grapher/grapher.cxx (ChildDeathReader::reap): New function. (StapLauncher): Keep a list of instantiated parsers. (StapLauncher::cleanup): Kill off all launched stap processes.
| * | More refactoring for multiple stap processes.Tim Moore2009-10-273-162/+173
| | | | | | | | | | | | | | | | | | | | | | | | | | | * grapher/StapParser.hxx (StapParser): Change _win and _widget from references to pointers. * grapher/StapParser.cxx (ioCallback): Ditto. * grapher/grapher.cxx (StapLauncher, GraphicalStapLauncher): Rewrite to make GraphicalStapLauncher a derived class of StapLauncher. (main): Accept graphing data from stdin with a "-" argument.
| * | Change stap parser to use an input file descriptor other than stdinTim Moore2009-10-273-16/+15
| |/ | | | | | | | | | | | | | | * grapher/StapParser.hxx (_inFd, getInFd, setInFd): new member and fuctions * grapher/StapParser.cxx (ioCallback): Use _inFd variable instead of stdin. * grapher/grapher.cxx (StapLauncher::launch): Don't read input from stap on stdin; use the the read end of the pipe.

| * | Added testsuite to test xulrunner sdt markers.Stan Cox2009-10-204-3/+136
| | | | | | | | | | | | | | | | | | | | | xulrunner.exp: New testsuite, modelled after mysql.exp. mysql.exp (stap-mysql.sh): Use installed stap. postgres.exp (stap-mysql.sh): Use installed stap. tcl.exp (stap-mysql.sh): Use installed stap.
| * | RHBZ519314: define task_struct cast to operate without debuginfoFrank Ch. Eigler2009-10-201-7/+7

| * Improve some runtime struct layoutsJosh Stone2009-10-193-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Guided by pahole, I've shaved off a few padding bytes here and there. New sizes on x86_64: stap_task_finder_target 192 -> 184 stap_itrace_probe 216 -> 208 stap_utrace_probe 328 -> 312 stap_uprobe_tf 200 -> 192 stap_uprobe_spec 48 -> 40 I only changed field layouts, not types or names, so this should be perfectly safe.

| * provide error message token/context if loc2c doesn'tFrank Ch. Eigler2009-10-191-0/+1
| | | | | | | | | | * tapsets.cxx (visit_target_symbol): When catching semantic_error, fill in token value if unset. Can happen for loc2c DIE() msgs.

* Avoid lockdep warnings.Srikar Dronamraju2009-10-192-14/+34
| | | | | | | | | | | | | | | | | | | | uprobe_fork_uproc() runs with parent_uproc->rwsem locked. However uprobe_mk_process() that gets called within uprobe_fork_uproc() also locks child_uproc->rwsem after initializing it. Lockdep report confuses this to acquiring a lock that already has been acquired and suggests using sub-classes. The alternatives we have are: 1. use classes level to distinguish different uproc structures. 2. unlock parent_uproc->rwsem before we call uprobe_fork_uproc(). 3. dont try locking child_uproc->rwsem; since we are protected by uproc_mutex as well as parent_uproc->rwsem; We use the last approach.

* PR10331: build fix for older nss reduxFrank Ch. Eigler2009-10-161-3/+2
| | | | | | | | Reported by Wenji, these SEC_* symbols were enums rather than macros, so instead of individual #ifdefs ... * stapsslerr.h: use NSS_{VMAJOR/VMINOR/VPATCH} to detect 3.12.4 or later for the two recent error symbols.
* Fix transok/tval-opt.stp testcase. Pick diffent function and non-empty block.Mark Wielaard2009-10-151-1/+2
| | | | | | | | | | | | This testcase succeeded just because the value being set couldn't be found. So the error message being compared was the same. Set -o pipefail to catch that case. On vta compiled kernels it failed because the optimizer turned { statement } into statement. So pick a function and argument which location can always be found and add an extra 'next' statement so the block isn't folded. * testsuite/transok/tval-opt.stp: Set -o pipefail. Add 'next' to make sure block isn't empty. Use "do_filp_open" and "mode".
* Updated checking for grapher dependencies.David Smith2009-10-158-269/+588
| | | | | | | | | | | | * configure.ac: Made sure nss includes will error even if only 1 header isn't usable. Added grapher dependencies gtkmm and boost headers. * Makefile.in: Regenerated. * config.in: Ditto. * configure: Ditto. * doc/Makefile.in: Ditto. * doc/SystemTap_Tapset_Reference/Makefile.in: Ditto. * grapher/Makefile.am: Use libglade CFLAGS/LIBS. * grapher/Makefile.in: Regenerated.
* PR10331: build fix for older nssFrank Ch. Eigler2009-10-151-0/+4
| | | | | | | * stapsslerr.h: #ifdef-conditionalize a few of the error codes, apparently defined some time after NSS 3.12.2. Reported-By: Wenji Huang <wenji.huang@oracle.com>

* Fix $$targets in dwarf probesJosh Stone2009-10-141-1/+1
| | | | | | My print_format refactoring in d5e178c1 missed an improperly-named token, an sprint that should be sprintf. Since the token value is now significant, that name needs to be correct.
* PR10331: more ssl error textFrank Ch. Eigler2009-10-141-0/+42
| | | | | | * stapsslerr.h: Added a few blurbs from mozilla sources. Added mozilla copyright/license header block, which lets us use this under GPLv2.
* PR10331: improve nss error message handlingFrank Ch. Eigler2009-10-146-72/+331
| | | | | | | | | * stapsslerr.h: New file containing NSS* error number to string mappings. Originally from mozilla NSS documentation, also seen in other GPLv2 software. * nsscommon.c (nssError): Print error number, and text from <stapsslerr.h>. * stap-{client,server}-connect.c (errWarn): Standardize on nssError(). * Makefile.am (nss binaries): Also link in nsscommon.c.
* Report experssion stack slot use back from loc2c.Roland McGrath2009-10-144-9/+23

* check for module-building Makefile more clearlyFrank Ch. Eigler2009-10-141-6/+5
