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.

RFC 8335 defines the network utility PROBE, which builds off of the
capabilities of Ping to query more detailed interface information from
networking nodes.

The definitions included in this patchset have been accepted into the
linux net-next branch and will be included in Linux 5.13. This
patchset adds the same definitions to the glibc for use in the
iputils package.

The relevant commits for the Linux definitions can be found here:
https://github.com/torvalds/linux/commit/e542d29ca81d005651680a0a697b72ca13ddc4cc
https://github.com/torvalds/linux/commit/750f4fc2a12f6632b5aa04526bf57fa06bfe8467

These changes have been tested by running the glibc tests on x86_64
