The following commit removes the requirement for patches to be placed in 1000, 2000, or 3000 ID blocks depending on their upstream status. Instead upstream status is documented in the header of the patch with some semi-standard notation as described in template.patch. The patches are re-numbered and defined and applied in the same order. Verified that before and after the patch that the source tree does not change. The patch definition is resorted to match the patch application order.

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.
