This is a major rewrite of the description of 'crypt', 'getentropy',
and 'getrandom'.
A few highlights of the content changes:
- Throughout the manual, public headers, and user-visible messages,
I replaced the term "password" with "passphrase", the term
"password database" with "user database", and the term
"encrypt(ion)" with "(one-way) hashing" whenever it was applied to
passphrases. I didn't bother making this change in internal code
or tests. The use of the term "password" in ruserpass.c survives,
because that refers to a keyword in netrc files, but it is adjusted
to make this clearer.
There is a note in crypt.texi explaining that they were
traditionally called passwords but single words are not good enough
anymore, and a note in users.texi explaining that actual passphrase
hashes are found in a "shadow" database nowadays.
- There is a new short introduction to the "Cryptographic Functions"
section, explaining how we do not intend to be a general-purpose
cryptography library, and cautioning that there _are_, or have
been, legal restrictions on the use of cryptography in many
countries, without getting into any kind of detail that we can't
promise to keep up to date.
- I added more detail about what a "one-way function" is, and why
they are used to obscure passphrases for storage. I removed the
paragraph saying that systems not connected to a network need no
user authentication, because that's a pretty rare situation
nowadays. (It still says "sometimes it is necessary" to
authenticate the user, though.)
- I added documentation for all of the hash functions that glibc
actually supports, but not for the additional hash functions
supported by libxcrypt. If we're going to keep this manual section
around after the transition is more advanced, it would probably
make sense to add them then.
- There is much more detailed discussion of how to generate a salt,
and the failure behavior for crypt is documented. (Returning an
invalid hash on failure is what libxcrypt does; Solar Designer's
notes say that this was done "for compatibility with old programs
that assume crypt can never fail".)
- As far as I can tell, the header 'crypt.h' is entirely a GNU
invention, and never existed on any other Unix lineage. The
function 'crypt', however, was in Issue 1 of the SVID and is now
in the XSI component of POSIX. I tried to make all of the
@standards annotations consistent with this, but I'm not sure I got
them perfectly right.
- The genpass.c example has been improved to use getentropy instead
of the current time to generate the salt, and to use a SHA-256 hash
instead of MD5. It uses more random bytes than is strictly
necessary because I didn't want to complicate the code with proper
base64 encoding.
- The testpass.c example has three hardwired hashes now, to
demonstrate that different one-way functions produce different
hashes for the same input. It also demonstrates how DES hashing
only pays attention to the first eight characters of the input.
- There is new text explaining in more detail how a CSPRNG differs
from a regular random number generator, and how
getentropy/getrandom are not exactly a CSPRNG. I tried not to make
specific falsifiable claims here. I also tried to make the
blocking/cancellation/error behavior of both getentropy and
getrandom clearer.
wint_t is a little finicky because it might be defined by stddef.h, which
belongs to the compiler.
In addition to the _types_, a bunch of other declarations shared between
wctype.h and wchar.h are factored out to their own header.
* libio/bits/types/FILE.h, libio/bits/types/__FILE.h
* wcsmbs/bits/types/mbstate_t.h, wcsmbs/bits/types/__mbstate_t.h
* wcsmbs/bits/types/wint_t.h: New single-type definition files.

(set_class_defaults): Fix format string.
* locale/programs/localedef.c (construct_output_path): Putting an
explicit \0 into the format string does not work, use %c.
Sat Oct 26 20:38:36 1996 Richard Henderson <rth@tamu.edu>
* Makerules: Install all shared libraries in $(slibdir).
* login/Makefile: Build libutil.so in others pass after
libc.so is created.
* misc/mntent.h: Include <paths.h> for _PATH_MNTTAB & _PATH_MOUNTED.
* string/stratcliff.c: Allocate 3 pages instead of one, then use
mprotect so that we know that the adjacent pages are inaccessible.
* resource/sys/resource.h: Move all structures and enums to ...
* sysdeps/generic/resourcebits.h: ... here ...
* sysdeps/unix/bsd/sun/sunos4/resourcebits.h: ... and here.
* sysdeps/unix/sysv/linux/alpha/resourcebits.h: Remove.
* sysdeps/unix/sysv/linux/i386/resourcebits.h: Remove.
* sysdeps/unix/sysv/linux/m68k/resourcebits.h: Remove.
* sysdeps/unix/sysv/linux/mips/resourcebits.h: Remove.
* sysdeps/unix/sysv/linux/resourcebits.h: New file. Use kernel
header for RLIMIT_* definitions. The members of struct rlimit
are longs.
Thu Oct 24 17:43:34 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* MakeTAGS (sysdep-dirs): Fix typo.
Wed Oct 23 03:45:22 1996 Ulrich Drepper <drepper@cygnus.com>
* Makefile (headers): Don't mention libc-version.h.
(install-others): ...but here.
* time/strptime.c: Recognize %s, %u, %g, and %G format.
nothing is found. This guarantees all subsequent calls behave
* sysdeps/unix/sysv/linux/syscalls.list: Change function name for
* io/getwd.c (getwd) [! PATH_MAX]: Don't assume that the user's
buffer is any longer than the amount necessary to hold the
filename; the Hurd getcwd uses the *entire* contents of the
buffer, however long it is specified to be.
* posix/getconf.c: De-ANSI-fy. Recognize POSIX.2 constant names.
since these do not depend on the platform.
Sat Aug 10 13:17:27 1996 David Mosberger-Tang <davidm@azstarnet.com>
* shadow.h: New file.
* sysdeps/unix/sysv/linux/netinet/in.h: Move
__BEGIN_DECLS/__END_DECLS up so ntohl() et al are bracketed as
well.
* socket/sys/socket.h [__cplusplus]: Use old-style __SOCKADDR_ARG.
g++ 2.7.2 (and earlier) has no transparent unions support.
Fri Aug 9 18:50:06 1996 David Mosberger-Tang <davidm@azstarnet.com>
* sysdeps/unix/sysv/linux/alpha/ioperm.c (_bus_base_sparse): New
function to determine the base address of sparse bus memory.
(APECS_*): Rename to CIA_*.
(APECS_SPARSE_MEM, CIA_SPARSE_MEM): New macros.
(platform): Add sparse_bus_memory_base member and initialize.
(sparse_bus_memory_base): New variable.
Tue Aug 6 10:23:18 1996 David Mosberger-Tang <davidm@azstarnet.com>
* sysdeps/posix/ttyname_r.c (ttyname_r),
sysdeps/posix/ttyname.c (ttyname): Return -1/NULL if
!__isatty(fd) (POSIX.1 says so.)
* sysdeps/unix/getlogin.c (getlogin): Fix to check fd 0 only.
This is not a gross hack, after all---for compatibility,
getlogin() really should check fd 0 only and not try to base its
operation on the controlling tty.
Wed Jul 17 10:54:20 1996 David Mosberger-Tang <davidm@azstarnet.com>
* sysdeps/unix/getlogin.c (getlogin): Add static variable NAME,
change utmp_data from static to auto.
Sun Aug 11 02:56:08 1996 Ulrich Drepper <drepper@cygnus.com>
* posix/unistd.h [__USE_MISC]: Add prototype for `nice'.
