| * Fix relay_old implementation of fsize_max and fnum_max.Masami Hiramatsu2009-09-091-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | With old relayfs, out_fd is used only when non-bulk mode. However, open_oldoutfile and open_relayfs_files open files with fopen and set only percpu_tmpfile. This will cause a problem with -S option, that out_fd will be closed when the file size reaches fsize_max and new fd will be opened only on percpu_tmpfile. So, out_fd should be synchronized with percpu_tmpfile. * runtime/staprun/relay_old.c (open_oldoutfile): Set fd of output file to out_fd[cpu]. (open_relayfs_files): Ditto.

* PR10524: reduce massive-uprobe script modules' .data consumptionFrank Ch. Eigler2009-09-085-127/+264
| | | | | | | | | | | | | | | | | | | | | | | | | | | The general approach is to rip out task_finder_tgt's from all over the place (including the unwindsym vmcbs, and the stap_uprobe_specs), and instead have a small handful of them: one for all unwindsyms, and one per abstract probed process (PID or NAME). These are in turn shared by all new stap_unwind_specs by index.

* PR10575: emit KERN_ERRORs on transport control message failuresFrank Ch. Eigler2009-09-081-0/+3
| | | | | | | | Suspecting that some kernel->user control messages may be getting lost, let's more robustly log these occurrences. * runtime/transport/control.c (_stp_ctl_send): printk(KERN_ERROR) instead of ignoring errors.

| | | | | | * task_finder.c (stap_start_task_finder): Emit _stp_dbug message at end rather at beginning, so printed utrace-engine attach counts reflect status at end of initialization rather than at beginning.
* runtime diagnostics: remove ANSI goo, add -DSTAP_DEBUG_PRINTK option.Frank Ch. Eigler2009-09-081-1/+8

* 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.

* 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).

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

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.
