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 7061 files FOO.

I then removed trailing white space from math/tgmath.h,
support/tst-support-open-dev-null-range.c, and
sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following
obscure pre-commit check failure diagnostics from Savannah.  I don't
know why I run into these diagnostics whereas others evidently do not.

remote: *** 912-#endif
remote: *** 913:
remote: *** 914-

malloc: Fix malloc debug for 2.35 onwards

2021-11-17T12:33:39+00:00

The change 1e5a5866cb ("Remove malloc hooks [BZ #23328]") has broken
ports that are using GLIBC_2_35, like the new OpenRISC port I am working
on.

The libc_malloc_debug.so library used to bring in the debug
infrastructure is currently essentially empty for GLIBC_2_35 ports like
mine causing mtrace tests to fail:

    cat sysdeps/unix/sysv/linux/or1k/shlib-versions
    DEFAULT                 GLIBC_2.35
    ld=ld-linux-or1k.so.1

    FAIL: posix/bug-glob2-mem
    FAIL: posix/bug-regex14-mem
    FAIL: posix/bug-regex2-mem
    FAIL: posix/bug-regex21-mem
    FAIL: posix/bug-regex31-mem
    FAIL: posix/bug-regex36-mem
    FAIL: malloc/tst-mtrace.

The issue seems to be with the ifdefs in malloc/malloc-debug.c. The
ifdefs are currently essentially exluding all symbols for ports > 2.35.

Removing the top level SHLIB_COMPAT ifdef allows things to just work.

Remove malloc hooks [BZ #23328]

2021-07-22T13:08:12+00:00

Make malloc hooks symbols compat-only so that new applications cannot
link against them and remove the declarations from the API.  Also
remove the unused malloc-hooks.h.

Finally, mark all symbols in libc_malloc_debug.so as compat so that
the library cannot be linked against.

Add a note about the deprecation in NEWS.
