Nick Alcock 211bcd0133 bfd, ld, libctf: skip zero-refcount strings in CTF string reporting 
This is a tricky one.  BFD, on the linker's behalf, reports symbols to
libctf via the ctf_new_symbol and ctf_new_dynsym callbacks, which
ultimately call ctf_link_add_linker_symbol.  But while this happens
after strtab offsets are finalized, it happens before the .dynstr is
actually laid out, so we can't iterate over it at this stage and
it is not clear what the reported symbols are actually called.  So
a second callback, examine_strtab, is called after the .dynstr is
finalized, which calls ctf_link_add_strtab and ultimately leads
to ldelf_ctf_strtab_iter_cb being called back repeatedly until the
offsets of every string in the .dynstr is passed to libctf.

libctf can then use this to get symbol names out of the input (which
usually stores symbol types in the form of a name -> type mapping at
this stage) and extract the types of those symbols, feeding them back
into their final form as a 1:1 association with the real symtab's
STT_OBJ and STT_FUNC symbols (with a few skipped, see
ctf_symtab_skippable).

This representation is compact, but has one problem: if libctf somehow
gets confused about the st_type of a symbol, it'll stick an entry into
the function symtypetab when it should put it into the object
symtypetab, or vice versa, and *every symbol from that one on* will have
the wrong CTF type because it's actually looking up the type for a
different symbol.

And we have just such a bug.  ctf_link_add_strtab was not taking the
refcounts of strings into consideration, so even strings that had been
eliminated from the strtab by virtue of being in objects eliminated via
--as-needed etc were being reported.  This is harmful because it can
lead to multiple strings with the same apparent offset, and if the last
duplicate to be reported relates to an eliminated symbol, we look up the
wrong symbol from the input and gets its type wrong: if it's unlucky and
the eliminated symbol is also of the wrong st_type, we will end up with
a corrupted symtypetab.

Thankfully the wrong-st_type case is already diagnosed by a
this-can-never-happen paranoid warning:

  CTF warning: Symbol 61a added to CTF as a function but is of type 1

or the converse

 * CTF warning: Symbol a3 added to CTF as a data object but is of type 2

so at least we can tell when the corruption has spread to more than one
symbol's type.

Skipping zero-refcounted strings is easy: teach _bfd_elf_strtab_str to
skip them, and ldelf_ctf_strtab_iter_cb to loop over skipped strings
until it falls off the end or finds one that isn't skipped.

README

This file contains invisible Unicode characters

This file contains invisible Unicode characters that are indistinguishable to humans but may be processed differently by a computer. If you think that this is intentional, you can safely ignore this warning. Use the Escape button to reveal them.

BFD is an object file library.  It permits applications to use the
same routines to process object files regardless of their format.

BFD is used by the GNU debugger, assembler, linker, and the binary
utilities.

The documentation on using BFD is scanty and may be occasionally
incorrect.  Pointers to documentation problems, or an entirely
rewritten manual, would be appreciated.

There is some BFD internals documentation in doc/bfdint.texi which may
help programmers who want to modify BFD.

BFD is normally built as part of another package.  See the build
instructions for that package, probably in a README file in the
appropriate directory.

BFD supports the following configure options:

  --target=TARGET
	The default target for which to build the library.  TARGET is
	a configuration target triplet, such as sparc-sun-solaris.
  --enable-targets=TARGET,TARGET,TARGET...
	Additional targets the library should support.  To include
	support for all known targets, use --enable-targets=all.
  --enable-64-bit-bfd
	Include support for 64 bit targets.  This is automatically
	turned on if you explicitly request a 64 bit target, but not
	for --enable-targets=all.  This requires a compiler with a 64
	bit integer type, such as gcc.
  --enable-shared
	Build BFD as a shared library.
  --with-mmap
	Use mmap when accessing files.  This is faster on some hosts,
	but slower on others.  It may not work on all hosts.

Report bugs with BFD to bug-binutils@gnu.org.

Patches are encouraged.  When sending patches, always send the output
of diff -u or diff -c from the original file to the new file.  Do not
send default diff output.  Do not make the diff from the new file to
the original file.  Remember that any patch must not break other
systems.  Remember that BFD must support cross compilation from any
host to any target, so patches which use ``#ifdef HOST'' are not
acceptable.  Please also read the ``Reporting Bugs'' section of the
gcc manual.

Bug reports without patches will be remembered, but they may never get
fixed until somebody volunteers to fix them.
