* bz10475.exp: Use filp_open which has a constant const char argument for test.Mark Wielaard2009-09-071-4/+3
| | | | | | | | | For some reason the do_filp_open const char *pathname argument has changed its name between different kernel versions. Luckily filp_open has a cont char *filename argument that is constant between versions (the test needs a const char* argument to do an array operation on). * testsuite/semok/bz10475.stp: Use filp_open instead of do_filp_open.
* PR10613 sys32_ustat is renamed compat_sys_ustat in 2.6.30 kernel.Mark Wielaard2009-09-072-2/+25
| | | | | | | | | | Note that the new compat_sys_ustat is asmlinkage and has a differently named argument for the user struct. * tapset/syscalls2.stp (syscall.ustat32): Add compat_sys_ustat variant. (syscall.ustat.return): Likewise. * tapset/nd_syscalls2.stp (nd_syscall.ustat32): Likewise. (nd_syscall.ustat.return): Likewise.
* Fix build-id check for relocatable kernelEugeniy Meshcheryakov2009-09-072-3/+5
| | | | | | Save offset of build id relative to _stext instead of absolute address for kernel and apply relocations at run-time. This fixes Debian bug #545277 (http://bugs.debian.org/545277).

| * | Use a regexp for matching blacklist sectionsJosh Stone2009-09-032-8/+16
| | | | | | | | | | | | | | | | | | | | | | | | We already use regexp for function/file blacklisting, so this just makes the section blacklisting consistent with the rest. * dwflpp.cxx (dwflpp::blacklisted_p): Use regexec instead of section==. (dwflpp::build_blacklist): Build blacklist_section too.
| * | Fetch the blacklist section only when neededJosh Stone2009-09-033-21/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We only check blacklisting on kernel probes, so it's a waste to dig up the section name otherwise. * dwflpp.cxx (dwflpp::blacklisted_p): Lookup the section directly. (relocate_address::relocate_address): Don't do blacklisting here. * tapsets.cxx (dwarf_query::add_probe_point): Don't carry the blacklist section directly anymore.
| * | PR10573: Squash duplicate inline instancesJosh Stone2009-09-032-1/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In C++, identical functions included in multiple CUs will get merged at link time into a single instance. We need to make sure that inlines within those merged functions are not probed multiple times. * tapsets.cxx (inline_instance_info::operator<): Used for set support. (dwarf_query::handle_query_module): Clear inline_dupes on each module. (query_dwarf_inline_instance): Squash this inline instance if it's already in the inline_dupes set.
| * | PR10572: Allow duplicate function names in a CUJosh Stone2009-09-023-24/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We can't assume that a given function name will only appear once in a CU. In C++, two functions may have the same name in different classes or namespaces, or even in the same scope with overloaded parameters. Even in C, the compiler may generate multiple copies of a single function with different optimizations. We now use a multimap for function names, so we shouldn't miss any. * dwflpp.h (cu_type_cache_t, mod_cu_type_cache_t): New typedef to keep a normal map for the global_alias_cache. (cu_function_cache_t): Use a multimap for function names. * dwflpp.cxx (dwflpp::iterate_over_functions): Walk over the range of exactly-matching functions. * tapsets.cxx (query_dwarf_func): Don't abort after seeing an exact match -- there could be more to come.
| * | Delete stuff that dwflpp newedJosh Stone2009-09-021-0/+17
| | | | | | | | | | | | * dwflpp.cxx (dwflpp::~dwflpp): Delete all of the caches.
| * | Provide backward-compatible unordered_map/setJosh Stone2009-09-022-20/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We were defining our own stap_map with a ::type to let us use typedefs to use the new unordered_map if available, or hash_map otherwise. Since unordered_map is the future direction, I'm changing our code to use that directly. The backward-compatible version is a #define to hash_map, which has a compatible interface. While I'm at it, let's also define unordered_multimap, unordered_set, and unordered_multiset. * unordered.h: New. * dwflpp.h (stap_map): Removed. (cache typedefs): Use the unordered name now.
| * | Unify lex_cast* and avoid string copiesJosh Stone2009-09-0214-105/+108
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We always use lex_cast either to string or from string, so I made that explicit, and got rid of some string copies in the process. There was also stringify(), which was redundant to lex_cast<string>. We also always used lex_cast_hex to string, so that's now hard-coded and again eliminated a string copy. For lex_cast_qstring<string>, there's no need to write the streamify the input, so a specialization now operates directly on the input. Hopefully this is a bit cleaner, and I do measure it to be a little faster on scripts with many probes.

| | | | | | | | | | | _stp_vscnprintf is only suitable for calls from the script, with slightly different conventions (64-bit ints/pointers, extra formatting directives). * runtime/runtime.h (_stp_{dbug,warn,error}): Add __attribute__ format(printf). * runtime/io.c (_stp_vlog): Ditto. Use vscnprintf(). * runtime/sym.c (_stp_module_check): Remove hexdumping (%.*M) of mismatching buildids.

* PR10581: Use ARCH for tracepoints and kernel typequeriesJosh Stone2009-09-012-1/+29
| | | | | | | | | | | | These are kernel modules that we generate for querying debuginfo, so they need to use the same ARCH settings that we put in the main script module. * buildrun.cxx (make_tracequery, make_typequery_kmod): Add the arch and kbuild flags to make_cmd. * hash.cxx (find_stapconf_hash, find_tracequery_hash, find_typequery_hash): The arch is in the base hash already, but add the kbuild flags too.

* Use a header-cast in nd_syscall.sigaltstackJosh Stone2009-08-311-1/+2
| | | | | | | | | The nd_syscalls tapset is meant to run with no debuginfo, so using a @cast into a module type defeats the purpose. We should use a @cast with a header name instead, so debuginfo is generated. * tapset/i386/nd_syscalls.stp (nd_syscall.sigaltstack): Get the pt_regs type definition from "kernel<asm/ptrace.h>".

| | | | | | | The argument fix in commit 77c26b4 needs to be made in nd_syscalls too, where the conditional kernel should be 2.6.30 instead of 2.6.29. * tapset/i386/nd_syscalls.stp (nd_syscall.sigaltstack): Check 2.6.30.
* Fix sys_sigaltstack ussp conditional.Mark Wielaard2009-08-291-1/+1
| | | | | | | | For i386 sys_sigaltstack changed argument params starting with kernel commit b12bda which was only included in 2.6.30, not in any 2.6.29 kernel. * tapset/i386/syscalls.stp (sys_sigaltstack): ussp conditional should be kernel_v < "2.6.30" for param change (from bx to regs).

| | | | | | | | | | | | | Instead of generating a warning the current kernel.statement probe produced a warning on some 386 kernels that had optimized that particular line: semantic error: multiple addresses for fs/bio.c:282 (try fs/bio.c:278 or fs/bio.c:284) semantic error: no match while resolving probe point kernel.statement("bio_init@fs/bio.c+3") So do as told to just get the expected warnings for this probe. * testsuite/systemtap.base/warnings.stp (probea): Probe bio_init@fs/bio.c+5.

* Cache inline instance lookupsJosh Stone2009-08-282-12/+52
| | | | | | | | | | | | | | | | | | | | We used to call dwarf_func_inline_instances to get the locations where inlines are used. This function has to iterate through nearly all DIEs to find instances, which is a lot of redundant work when we're probing multiple inline functions. Now we have our own dwarf iterator to cache all inline instances back to their origin. This only needs to be called once for each CU, and all further inlines are just a map lookup. Some quick benchmarks: stap -l Before After kernel.function("*") 25010ms 2110ms module("*").function("*") 86550ms 16920ms process("stap").function("*") 41330ms 580ms * dwflpp.cxx (dwflpp::cu_inl_function_caching_callback): Removed. (dwflpp::cache_inline_instances): New caching iterator. (dwflpp::iterate_over_inline_instances): Cache each CU once.
