* 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>
* Add boost-devel build requirement for the grapher.David Smith2009-10-151-0/+5

* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem in this bug is that our statement(NUM) lookup was only searching for the outermost function (not inlined) which contains the PC in question. When that PC happens to be the beginning of the function and also the beginning of an inline, the caching was using the wrong variable scope. The function/statement(NUM) lookup has been rewritten to bypass all of the CU and function iteration, and just go straight to a getscopes(pc) lookup, so it will now always use the innermost containing die for the variable scope. * tapsets.cxx (query_addr): New, short-circuit for numeric probes.
