This patch was automatically generated by running the following shell
script, which uses GNU sed, and which avoids modifying files imported
from upstream:

sed -ri '

and then by running 'make dist-prepare' to regenerate files built
from the altered files, and then executing the following to cleanup:

  chmod a+x sysdeps/unix/sysv/linux/riscv/configure
  # Omit irrelevant whitespace and comment-only changes,
  # perhaps from a slightly-different Autoconf version.
  git checkout -f \
    sysdeps/csky/configure \

    sysdeps/riscv/configure \
    sysdeps/unix/sysv/linux/csky/configure
  # Omit changes that caused a pre-commit check to fail like this:

  git checkout -f sysdeps/sparc/sparc64/multiarch/memcpy-ultra3.S

The GNU Coding Standards specify that line breaks in expressions
should go before an operator, not after one.  This patch fixes various
code to do this.  It only changes code that appears to be mostly
following GNU style anyway, not files and directories with
substantially different formatting.  It is not exhaustive even for
files using GNU style (for example, changes to sysdeps files are
deferred for subsequent cleanups).  Some files changed are shared with
gnulib, but most are specific to glibc.  Changes were made manually,
with places to change found by grep (so some cases, e.g. where the
operator was followed by a comment at end of line, are particularly
liable to have been missed by grep, but I did include cases where the
operator was followed by backslash-newline).

This patch generally does not attempt to address other coding style
issues in the expressions changed (for example, missing spaces before
'(', or lack of parentheses to ensure indentation of continuation
lines properly reflects operator precedence).

Tested for x86_64, and with build-many-glibcs.py.

This removes all overrides of TIMEOUT that are less than or equal to the
default timeout.

Some Linux distributions are experimenting with a new, separately
maintained and hopefully more agile implementation of the crypt
API.  To facilitate this, add a configure option which disables
glibc's embedded libcrypt.  When this option is given, libcrypt.*
and crypt.h will not be built nor installed.

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.

The functions encrypt, setkey, encrypt_r, setkey_r, cbc_crypt,
ecb_crypt, and des_setparity should not be used in new programs,
because they use the DES block cipher, which is unacceptably weak by
modern standards.  Demote all of them to compatibility symbols, and
remove their prototypes from installed headers.  cbc_crypt, ecb_crypt,
and des_setparity were already compat symbols when glibc was
configured with --disable-obsolete-rpc.

POSIX requires encrypt and setkey to be available when _XOPEN_CRYPT
is defined, so this change also removes the definition of X_OPEN_CRYPT
from <unistd.h>.

The entire "DES Encryption" section is dropped from the manual, as is
the mention of AUTH_DES and FIPS 140-2 in the introduction to
crypt.texi.  The documentation of 'memfrob' cross-referenced the DES
Encryption section, which is replaced by a hyperlink to libgcrypt, and
while I was in there I spruced up the actual documentation of
'memfrob' and 'strfry' a little.  It's still fairly jokey, because
those functions _are_ jokes, but they do also have real use cases, so
people trying to use them for real should have all the information
they need.

DES-based authentication for Sun RPC is also insecure and should be
deprecated or even removed, but maybe that can be left as TI-RPC's
problem.

The value of 'cd.initialized' is left uninitialized before the
first invocation of 'crypt_r ()' in this test despite the fact
that it should be set to zero according to the API.
