Short description: Deprecate libcrypt.
Author(s): Zack Weinberg <zackw@panix.com>
Origin: https://sourceware.org/ml/libc-alpha/2017-08/msg01257.html
Bug-Fedora: #1566464
Upsteram status: https://patchwork.sourceware.org/patch/22401/
Additionally we need to review:
https://patchwork.sourceware.org/patch/26750/
and revisit the issues around bug rhbz1566464.
Background information:
https://sourceware.org/ml/libc-alpha/2017-08/msg01257.html
https://fedoraproject.org/wiki/Changes/Replace_glibc_libcrypt_with_libxcrypt
From: Zack Weinberg <zackw@panix.com>
Subject: [PATCH] Deprecate libcrypt and don't build it by default
Back in June, Björn Esser proposed to add OpenBSD-compatible bcrypt
support to our implementation of crypt(3), and Zack Weinberg replied
that it might actually make more sense to _remove_ libcrypt from
glibc, freeing up libcrypt.so.1 and crypt.h to be provided by a
separate project that could move faster. (For instance, libxcrypt:
https://github.com/besser82/libxcrypt)
This patch disables build and installation of libcrypt by default. It
can be re-enabled with --enable-obsolete-crypt to configure. Unlike
libnsl, we do *not* install a runtime shared library; that's left to
the replacement. (Unlike the SunRPC situation, I think we can
probably drop this code altogether in a release or two.)
The function prototypes for crypt and encrypt are removed from
unistd.h, and the function prototype for setkey is removed from
stdlib.h; they do *not* come back with --enable-obsolete-crypt. This
means glibc no longer provides the POSIX CRYPT option, and the macro
_XOPEN_CRYPT is also removed from unistd.h to indicate that.
(_SC_XOPEN_CRYPT is still defined, but sysconf(_SC_XOPEN_CRYPT) will
return -1 at runtime.) These functions are also unconditionally
removed from conform/data/{stdlib,unistd}.h-data.
* posix/unistd.h (_XOPEN_CRYPT, crypt, encrypt): Don't declare.
* stdlib/stdlib.h (setkey): Don't declare.
* configure.ac (--enable-obsolete-crypt): New configure option.
* configure: Regenerate.
* config.make.in (build-obsolete-crypt): New makefile variable.
* crypt/Banner: Delete file.
* crypt/Makefile: Don't build anything unless
$(build-obsolete-crypt) is 'yes'.
* sysdeps/sparc/sparc32/sparcv9/multiarch/Makefile: Only add things
to libcrypt-sysdep_routines when $(build-obsolete-crypt) is 'yes'.
* sysdeps/sparc/sparc64/multiarch/Makefile: Likewise.
* sysdeps/unix/sysv/linux/arm/Makefile: Likewise.
* conform/Makefile: Only include libcrypt.a in linknamespace tests
when $(build-obsolete-crypt) is 'yes'.
* conform/data/stdlib.h-data (setkey): Don't expect.
* conform/data/unistd.h-data (crypt, encrypt): Don't expect.
* elf/Makefile: Only perform various tests of libcrypt.so/libcrypt.a
when $(build-obsolete-crypt) is 'yes'.
* elf/tst-linkall-static.c: Don't include crypt.h when USE_CRYPT
is false.

After commit d76d3703551a362b472c866b5b6089f66f8daa8e ("Fix missing
timespec definition for sys/stat.h (BZ #21371)"), sanitizer builds start
to fail due to a conflicting definition of struct timespec in
<linux/time.h>. Define _STRUCT_TIMESPEC, which is already checked in
the kernel header, to support including <linux/time.h> after
<sys/stat.h>.
