bab84a13ff Additional PAM cleanup:
* src/userdel.c, src/newusers.c, src/chpasswd.c, src/chfn.c,
	src/groupmems.c, src/usermod.c, src/groupdel.c, src/chgpasswd.c,
	src/useradd.c, src/groupmod.c, src/groupadd.c, src/chage.c,
	src/chsh.c: If the username cannot be determined, report it as
	such (not a PAM authentication failure).

f8aef607ae * configure.in: Added option --enable-account-tools-setuid to
enable/disable the usage of PAM to authenticate the callers of
	account management tools: chage, chgpasswd, chpasswd, groupadd,
	groupdel, groupmod, useradd, userdel, usermod.
	* src/Makefile.am: Do not link the above tools with libpam if
	account-tools-setuid is disabled.
	* src/userdel.c, src/newusers.c, src/chpasswd.c, src/usermod.c,
	src/groupdel.c, src/chgpasswd.c, src/useradd.c, src/groupmod.c,
	src/groupadd.c, src/chage.c: Implement ACCT_TOOLS_SETUID
	(--enable-account-tools-setuid).
	* etc/pam.d/Makefile.am: Install the pam service file for the
	above tools only when needed.
	* src/useradd.c, src/userdel.c, src/usermod.c: It is no more
	needed to initialize retval to PAM_SUCCESS.

	src/useradd.c, src/groupmod.c, src/groupadd.c, src/chage.c,
	src/chsh.c: Simplify the PAM error handling. Do not keep the pamh
	handle, but terminate the PAM transaction as soon as possible if
	there are no PAM session opened.

	src/groupadd.c, src/chage.c, src/login.c, src/grpconv.c,
	src/groups.c, src/grpunconv.c, src/chsh.c: Prog is now global (not
	static to the file) so that it can be used by the helper functions
	of libmisc.
	* lib/prototypes.h: Added extern char *Prog.
	* libmisc/find_new_gid.c, libmisc/find_new_uid.c: Indicate the
	program name with the warning.

c9119dc6bb * src/newusers.c: Open syslog with the right identification name.
* src/newusers.c: Mark the files as locked only if they are really

eb6cb5311b * src/newusers.c: Report failure to unlock the passwd or shadow
file to stderr and syslog.
	* src/newusers.c: In case of error when files are open or closed,
	indicate the failing file.
	* src/newusers.c: Do not try to unlock the files manually since
	this is done in fail_exit.

	failures to lock or open the databases. This might be harmless,
	and the logs were not already informed that a change was

	* src/usermod.c: It's not the account which is unlocked, but its
	password.

	* src/grpck.c, src/newusers.c, src/usermod.c, src/useradd.c,
	src/groupmod.c, src/pwck.c, src/groupadd.c: Use is_valid_user_name
	and is_valid_group_name, following above change.
	* libmisc/chkname.c: Avoid implicit conversion of chars to
	booleans. Add brackets and parenthesis.

4e01ea6c33 * NEWS: newusers will behave more like useradd.
* src/newusers.c: The user's ID must be found before the group ID
	to mimic useradd's behavior choices of UID and GID.
	* src/newusers.c: Reuse the generic find_new_uid() and
	find_new_gid() functions. This permits to respect the
	UID_MIN/UID_MAX and GID_MIN/GID_MAX variables, should 
	* src/newusers.c: Check if the user or group exist using the
	external databases (with the libc getpwnam/getgrnam functions).
	Refuse to update an user which exist in an external database but
	does not exist in the local database.
	* src/newusers.c: Check the usernames and groupnames with
	check_user_name() and check_group_name()
	* src/newusers.c: Use isdigit() for readability.
	* src/newusers.c: Check if numerical IDs are valid (no remaining
	chars).

	* NEWS, src/newusers.c: Fix the support for the NONE crypt method.

	* src/newusers.c: Fix shadow group support (the list of admins was
	not defined; it is now set to an empty list).

4d606cc690 * configure.in: New configure option: --with-sha-crypt enabled by
default. Keeping the feature enabled is safe. Disabling it permits
  to disable the references to the SHA256 and SHA512 password
  encryption algorithms from the usage help and manuals (in addition
  to the support for these algorithms in the code).
* libmisc/obscure.c, libmisc/salt.c, src/newusers.c,
  src/chpasswd.c, src/chgpasswd.c, src/passwd.c: ENCRYPT_METHOD is
  always supported in login.defs. Remove the ENCRYPTMETHOD_SELECT
  preprocessor condition.
* libmisc/obscure.c, libmisc/salt.c, src/newusers.c,
  src/chpasswd.c, src/chgpasswd.c, src/passwd.c: Disable SHA256 and
  SHA512 if USE_SHA_CRYPT is not defined (this corresponds to a
  subset of the ENCRYPTMETHOD_SELECT sections).

0b695f5a76 * lib/prototypes.h, libmisc/salt.c: Add parameters to
crypt_make_salt to force the crypt method and number of rounds.
* libmisc/salt.c: Add parameter to SHA_salt_rounds to force the
  number of rounds.
* libmisc/salt.c, lib/getdef.c: ENCRYPT_METHOD and MD5_CRYPT_ENAB
  are needed also when USE_PAM (e.g. for chpasswd).
* src/newusers.c, src/gpasswd.c: Use the new crypt_make_salt prototype.
* src/chpasswd.c, src/chgpasswd.c: Add option -c, --crypt-method
  and -s, --sha-rounds to specify the crypt method and number of
  rounds in case of one of the SHA methods. The new prototype of
  crypt_make_salt simplifies the handling of -m, --md5.

39e5c0a1ab Fix some compilation warnings:
* src/login.c: "dereferencing type-punned pointer will break

 * lib/commonio.c: do not initialize the sb stat structure.
 * lib/pwio.c, lib/shadowio.c, lib/sgroupio.c, lib/groupio.c:
   initialize the security context if WITH_SELINUX.
 * lib/nscd.c: The service argument is not const (used in the exec*
   parameters). This matches with the prototype definition.
 * src/groupmems.c: Avoid ++i when i is also used in the same line.
 * src/newusers.c: i is positive every time it is compared. Add
   cast to unsigned int.
 * src/nologin.c: Use a main() prototype with no arguments.
 * libmisc/getdate.y: Initialize the type and value fields of the
   terminating entry for each TABLE.
 * libmisc/tz.c: Use "TZ=CST6CDT" as the default timezone.

libmisc/xgetXXbyYY.c, libmisc/xgetpwnam.c, libmisc/xgetpwuid.c,
  libmisc/xgetgrnam.c, libmisc/xgetgrgid.c, libmisc/xgetspnam.c:
  Added functions xgetpwnam(), xgetpwuid(), xgetgrnam(),
  xgetgrgid(), and xgetspnam(). They allocate memory for the
  returned structure and are more robust to successive calls. They
  are implemented with the libc's getxxyyy_r() functions if
  available.
* libmisc/limits.c, libmisc/entry.c, libmisc/chowntty.c,

  src/groupadd.c, src/chage.c, src/login.c, src/suauth.c,
  src/faillog.c, src/groups.c, src/chsh.c, src/id.c: Review all the
  usage of one of the getpwnam(), getpwuid(), getgrnam(),
  getgrgid(), and getspnam() functions. It was noticed on
  http://bugs.debian.org/341230 that chfn and chsh use a passwd
  structure after calling a pam function, which result in using
  information from the passwd structure requested by pam, not the
  original one. It is much easier to use the new xget... functions
  to avoid these issues. I've checked which call to the original
  get... functions could be left (reducing the scope of the
  structure if possible), and I've left comments to ease future
  reviews (e.g. /* local, no need for xgetpwnam */).
  Note: the getpwent/getgrent calls should probably be checked also.
* src/groupdel.c, src/expiry.c: Fix typos in comments.
* src/groupmod.c: Re-indent.
* libmisc/Makefile.am, lib/groupmem.c, lib/groupio.c, lib/pwmem.c,
  lib/pwio.c, lib/shadowmem.c, lib/shadowio.c: Move the __<xx>_dup
  functions (used by the xget... functions) from the <xx>io.c files
  to the new <xx>mem.c files. This avoid linking some utils against
  the SELinux library.
