Alan Modra 8ab91a0335 Re: PR32399, buffer overflow printing core_file_failing_command
Fix more potential buffer overflows, and correct trad-code.c and
cisco-core.c where they should be using bfd_{z}alloc rather than
bfd_{z}malloc.  To stop buffer overflows with fuzzed objects that
don't have a terminator on the core_file_failing_command string, this
patch allocates an extra byte at the end of the entire header buffer
rather than poking a NUL at the end of the name array (u_comm[] or
similar) because (a) it's better to not overwrite the file data, and
(b) it is possible that some core files make use of fields in struct
user beyond the end of u_comm to extend the command name.  The patch
also changes some unnecessary uses of bfd_zalloc to bfd_alloc.
There's not much point in clearing memeory that will shortly be
completely overwritten.

	PR 32399
	* aix5ppc-core.c (xcoff64_core_p): Allocate an extra byte to
	ensure the core_file_failing_command string is terminated.
	* netbsd-core.c (netbsd_core_file_p): Likewise.
	* ptrace-core.c (ptrace_unix_core_file_p): Likewise.
	* rs6000-core.c (rs6000coff_core_p): Likewise.
	* trad-core.c (trad_unix_core_file_p): Likewise, and bfd_alloc
	tdata rather than bfd_zmalloc.
	* cisco-core.c (cisco_core_file_validate): bfd_zalloc tdata.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
