2b778ceb40 Update copyright dates with scripts/update-copyrights 
I used these shell commands:

../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright
(cd ../glibc && git commit -am"[this commit message]")

and then ignored the output, which consisted lines saying "FOO: warning:
copyright statement not found" for each of 6694 files FOO.
I then removed trailing white space from benchtests/bench-pthread-locks.c
and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this
diagnostic from Savannah:
remote: *** pre-commit check failed ...
remote: *** error: lines with trailing whitespace found
remote: error: hook declined to update refs/heads/master

5a82c74822 Prefer https to http for gnu.org and fsf.org URLs 
Also, change sources.redhat.com to sourceware.org.
This patch was automatically generated by running the following shell
script, which uses GNU sed, and which avoids modifying files imported
from upstream:

sed -ri '
  s,(http|ftp)(://(.*\.)?(gnu|fsf|sourceware)\.org($|[^.]|\.[^a-z])),https\2,g
  s,(http|ftp)(://(.*\.)?)sources\.redhat\.com($|[^.]|\.[^a-z]),https\2sourceware.org\4,g
' \
  $(find $(git ls-files) -prune -type f \
      ! -name '*.po' \
      ! -name 'ChangeLog*' \
      ! -path COPYING ! -path COPYING.LIB \
      ! -path manual/fdl-1.3.texi ! -path manual/lgpl-2.1.texi \
      ! -path manual/texinfo.tex ! -path scripts/config.guess \

      ! '(' -name preconfigure \
            -execdir test -f preconfigure.ac ';' ')' \
      -print)

and then by running 'make dist-prepare' to regenerate files built
from the altered files, and then executing the following to cleanup:

  chmod a+x sysdeps/unix/sysv/linux/riscv/configure
  # Omit irrelevant whitespace and comment-only changes,
  # perhaps from a slightly-different Autoconf version.
  git checkout -f \
    sysdeps/csky/configure \

4e2f43f842 Use PRINTF_FORTIFY instead of _IO_FLAGS2_FORTIFY (bug 11319) 
The _chk variants of all of the printf functions become much simpler.
This is the last thing that we needed _IO_acquire_lock_clear_flags2
for, so it can go as well.  I took the opportunity to make the headers
included and the names of all local variables consistent across all the
affected files.

Since we ultimately want to get rid of __no_long_double as well, it
must be possible to get all of the nontrivial effects of the _chk
functions by calling the _internal functions with appropriate flags.
For most of the __(v)xprintf_chk functions, this is covered by
PRINTF_FORTIFY plus some up-front argument checks that can be
duplicated.  However, __(v)sprintf_chk installs a custom jump table so
that it can crash instead of overflowing the output buffer.  This
functionality is moved to __vsprintf_internal, which now has a
'maxlen' argument like __vsnprintf_internal; to get the unsafe
behavior of ordinary (v)sprintf, pass -1 for that argument.

obstack_printf_chk and obstack_vprintf_chk are no longer in the same
file.

As a side-effect of the unification of both fortified and non-fortified
vdprintf initialization, this patch fixes bug 11319 for __dprintf_chk
and __vdprintf_chk, which was previously fixed only for dprintf and
vdprintf by the commit

commit 7ca890b88e
Author: Ulrich Drepper <drepper@redhat.com>
Date:   Wed Feb 24 16:07:57 2010 -0800

    Fix reporting of I/O errors in *dprintf functions.

This patch adds a test case to avoid regressions.

Tested for powerpc and powerpc64le.

698fb75b9f Add __v*printf_internal with flags arguments 
There are a lot more printf variants than there are scanf variants,
and the code for setting up and tearing down their custom FILE
variants around the call to __vf(w)printf is more complicated and
variable.  Therefore, I have added _internal versions of all the
v*printf variants, rather than introducing helper routines so that
they can all directly call __vf(w)printf_internal, as was done with
scanf.

As with the scanf changes, in this patch the _internal functions still
look at the environmental mode bits and all callers pass 0 for the
flags parameter.

Several of the affected public functions had _IO_ name aliases that
were not exported (but, in one case, appeared in libio.h anyway);
I was originally planning to leave them as aliases to avoid having
to touch internal callers, but it turns out ldbl_*_alias only work
for exported symbols, so they've all been removed instead.  It also
turns out there were hardly any internal callers.  _IO_vsprintf and
_IO_vfprintf *are* exported, so those two stick around.

Summary for the changes to each of the affected symbols:

  _IO_vfprintf, _IO_vsprintf:
    All internal calls removed, thus the internal declarations, as well
    as uses of libc_hidden_proto and libc_hidden_def, were also removed.
    The external symbol is now exposed via uses of ldbl_strong_alias
    to __vfprintf_internal and __vsprintf_internal, respectively.

  _IO_vasprintf, _IO_vdprintf, _IO_vsnprintf,
  _IO_vfwprintf, _IO_vswprintf,
  _IO_obstack_vprintf, _IO_obstack_printf:
    All internal calls removed, thus declaration in internal headers
    were also removed.  They were never exported, so there are no
    aliases tying them to the internal functions.  I.e.: entirely gone.

  __vsnprintf:
    Internal calls were always preceded by macros such as
      #define __vsnprintf _IO_vsnprintf, and
      #define __vsnprintf vsnprintf
    The macros were removed and their uses replaced with calls to the
    new internal function __vsnprintf_internal.  Since there were no
    internal calls, the internal declaration was also removed.  The
    external symbol is preserved with ldbl_weak_alias to ___vsnprintf.

  __vfwprintf:
    All internal calls converted into calls to __vfwprintf_internal,
    thus the internal declaration was removed.  The function is now a
    wrapper that calls __vfwprintf_internal.  The external symbol is
    preserved.

  __vswprintf:
    Similarly, but no external symbol.

  __vasprintf, __vdprintf, __vfprintf, __vsprintf:
    New internal wrappers.  Not exported.

  vasprintf, vdprintf, vfprintf, vsprintf, vsnprintf,
  vfwprintf, vswprintf,
  obstack_vprintf, obstack_printf:
    These functions used to be aliases to the respective _IO_* function,
    they are now aliases to their respective __* functions.

Tested for powerpc and powerpc64le.

db3476aff1 libio: Implement vtable verification [BZ #20191] 
This commit puts all libio vtables in a dedicated, read-only ELF
section, so that they are consecutive in memory.  Before any indirect
jump, the vtable pointer is checked against the section boundaries,
and the process is terminated if the vtable pointer does not fall into
the special ELF section.

To enable backwards compatibility, a special flag variable
(_IO_accept_foreign_vtables), protected by the pointer guard, avoids
process termination if libio stream object constructor functions have
been called earlier.  Such constructor functions are called by the GCC
2.95 libstdc++ library, and this mechanism ensures compatibility with
old binaries.  Existing callers inside glibc of these functions are
adjusted to call the original functions, not the wrappers which enable
vtable compatiblity.

The compatibility mechanism is used to enable passing FILE * objects
across a static dlopen boundary, too.
