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
Suppress or avoid warnings in tests that exercise failure modes by making
calls with invalid arguments.

sys/socket.h includes sys/uio.h to get the definition of the iovec
structure.
POSIX allows sys/socket.h to make all sys/uio.h symbols visible.
However, all of sys/uio.h is XSI-shaded, so for non-XSI POSIX this
results in conformtest failures (for sys/socket.h and other headers
that include it):
Namespace violation: "UIO_MAXIOV"
Namespace violation: "readv"
Namespace violation: "writev"
Now, there is some ambiguity in POSIX about what namespace
reservations apply in this case - see
http://austingroupbugs.net/view.php?id=1127 - but glibc convention
would still avoid declaring readv and writev, for example, for feature
test macros that don't include them (if only headers from the relevant
standard are included), even if such declarations are permitted, so
there is a bug here according to glibc conventions.
This patch moves the struct iovec definition to a new
bits/types/struct_iovec.h header and includes that from sys/socket.h
instead of including the whole of sys/uio.h. This fixes the namespace
issue; however, three files in glibc that were relying on the implicit
inclusion needed to be updated to include sys/uio.h explicitly. So
there is a question of whether sys/socket.h should continue to include
sys/uio.h under some conditions, such as __USE_XOPEN or __USE_MISC or
__USE_XOPEN || __USE_MISC, for greater compatibility with code that
(wrongly) expects this optional inclusion to be present there. (I
think the three affected files in glibc should still have explicit
sys/uio.h inclusions added in any case, however.)
Tested for x86_64.

<bits/types/struct_iovec.h>.

of <sys/uio.h>.

This patch fixes multiple issues of test-errno.c (9a56f87183):
- Rename Linux test-errno.c to test-errno-linux.c to avoid build
the same source for both tests.
- Add a mlock check for 32 bits build running on 64 bits kernels.
Althuough man pages states that mlock fails with EINVAL if final
address overflows, kernels does not return it for aforementioned
condition (it returns ENOMEM instead). Although it seems to be
a kernel issue for compat syscall handling, I think it is worth
to still check syscall return and document the behavior.
- Initialize option lenght for setsockopt check.
- Change open test from EINVAL to EISDIR.
Checked on x86_64-linux-gnu and i686-linux-gnu (running on 64 bits
kernel).
* posix/test-errno.c (do_test): Initialize setsockopt optlen.
* sysdeps/unix/sysv/linux/test-errno.c: Move to ...
* sysdeps/unix/sysv/linux/test-errno-linux.c: ... here.
(test_wrp_rv): Fix format.
(test_wrp_rv2): New macro.
(do_test): Handle mlock return on 64 bits kernels with 32 bits
binaries.
This patch adds tests for POSIX and Linux specific syscalls
that implemented with syscall templates machinery. The reason
of tests is to receive the expected error code and test if
it's handled properly by glibc.
