* 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

* 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.

| | | | | | | | | * 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.

This way we don't have so much duplication in initializing the print flags. * staptree.cxx (print_format::parse_print): Replaced with...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Inline functions do not have an indentifiable return point and require kernel built using VTA-enabled gcc to get tracking of variables. OTOH syscall functions are very rarely inlined (depending on the compiler mood), therefore filtering probes to include only non-inlined functions ensures consistent behavior between different kernels. This removes the problem of inaccessible variables in inlined syscalls that is described in comments #6-9 to PR5890 and gives us the status quo w.r.t. syscall probing, because before the commit solving PR10572 (b7478964) inline instances were masked anyway by non-inline ones. You can check whether you have inlined syscalls using following command: $ stap -l 'kernel.function("sys_*"),kernel.function("compat_sys_*")' \ 2>&1 -vvv | awk '/^selected inline/{print $5}' * tapset/syscalls.stp: Add .call to all entry probes. * tapset/syscalls2.stp: Ditto.
