Don't crash untraced calls via PLT in prelinked PPC64 binaries

In prelinked binaries, ltrace has to unprelinks PLT slots in order to
catch calls done through PLT.  This makes the calls done through these
slots invalid, because the special first PLT slot is not initialized,
and dynamic linker SIGSEGVs because of this.  Ltrace relies on
arranging breakpoints such that the dynamic linker is not actually
entered, and moves PC around itself to simulate the effects of a call
through PLT.

Originally, arch_elf_add_plt_entry was called only for symbols that
were actually traced.  Later this was changed and it's now called for
all PLT entries, and the resulting candidate list is filtered
afterwards.  This gives backends a chance to rename the symbol, as is
useful with IRELATIVE PLT calls, where symbol name may not be
available at all.  But the PPC backend was never updated to reflect
this, and unresolved all symbols for which arch_elf_add_plt_entry was
called, thus rendering _all_ PLT slots invalid, even those that
weren't later procted by breakpoints.  Thus calls done through any
untraced slots failed.

This patch fixes this problem by deferring the unprelinking of PLT
slots into the on_install hook of breakpoints.

10 years agoAdd support for using elfutils as unwinder.

Add support for using elfutils as unwinder.

This adds support for using elfutils as unwinder with -w. Since elfutils
0.158 elfutils contains a simple unwinder interface that matches nicely
on the ltrace backtrace support.

The code reuses the libunwind infrastructure already in ltrace where
possible (by defining HAVE_UNWINDER which is 1 if either libunwind or
elfutils is used). It also reuses the ltrace proc_add_library callback
to keep track of the ELF files mapped for the unwinder.

The current implementation matches the output as if libunwind was used.
But elfutils can also provide some more information since it can lookup
the DWARF debuginfo. So if the source info of an address can be found
through elfutils the backtrace will also include this as an additional
output line per frame.

Fix a problem in tracing across fork on PPC64

In order to avoid single-stepping through large portions of the
dynamic linker, ltrace remembers at which address the instruction that
resolved a PLT slot is.  It then puts a breakpoint to this address so
that it can fast-forward to that address next time it needs to catch a
PLT slot being resolved.

When a process is cloned, the pointer to this breakpoint is simply
copied over to the new process, instead of being looked up in the new
process structures.  This patches fixes this.

Consider exec and exit events an end of outstanding calls

  those cleaned-up interfaces).

- trace-exec.exp was extended to check that the exec syscall can be
  seen in -c output.  That's one of the symptoms of what this fixes.

- This hides dict_opt_c in summary.c.  It also gets rid of the global
  variable current_time_spent--instead, the information is passed via
  a function argument in a struct timedelta (so that we never confuse
