| * PR10461: Match C++ scopes for namespaces and classesJosh Stone2009-09-163-71/+167
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function spec for dwarf probes now supports scopes, so you can limit the probes to specific namespaces or classes. Multiple scopes can be specified, and they will be matched progressively outward. probe process("foo").function("std::vector<*>::*") { ... } probe process("foo").function("::global_function") { ... } * dwflpp.cxx (dwflpp::get_parent_scope): New, finds the containing scopes of the specified DIE. (dwflpp::function_scope_matches): New, checks that the scopes containing the function all match the given scope patterns. * tapsets.cxx (dwarf_query::parse_function_spec): Rewrite, now handles multiple scope separators too. (query_dwarf_func): Check that the functions scopes match.

* | PR10650: markup some unprivileged-safe tapset functionsFrank Ch. Eigler2009-09-1611-63/+155
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add /* unprivileged */ to a variety of tapset embedded-c functions, together with uid-assertion-checking code as needed. This is only an initial set, and may need to grow or shrink after further testing. Prototyped-By: Dave Brolley <brolley@redhat.com> * runtime/runtime.h (is_myproc, assert_is_myproc): New macros. * runtime/addr-map.c (lookup_bad_addr): Reject if !is_myproc in unprivileged mode. * runtime/print.c (_stp_print_kernel_info): Add unprivileged mode info. * tapset/DEVGUIDE: Document /* pure */ and /* unprivileged */. * tapset/*.stp: Add /* unprivileged */ here and there, in questionable cases along with an assert_is_myproc().

(switchfile_handler): Send SIGUSR2 signal to reader threads for file switching. (init_oldrelayfs): Assign switchfile_handler to SIGUSR2.

| | | | | | | | | | | | | | | | | | | | | | Do the same workaround as loc2c-test.c does. Just treat a constant member location offset as a DW_OP_plus_uconst and call c_translate_location for it. Also Remove c_translate_add_offset. * dwflpp.cxx (dwflpp::translate_location): Check elfutils version and only do workaround for elfutils < 0.142. * loc2c.h (c_translate_add_offset): Removed. * loc2c.c (c_translate_add_offset): Likewise.

| | | | | | | | | | | | * loc2c-test.c (handle_variable): Skip the workaround for elfutils 0.142. When doing it, use a synthetic location expression. Never use c_translate_add_offset, which is broken.
