 # shadow-utils
 ## Introduction
 The shadow-utils package includes the necessary programs for
 converting UNIX password files to the shadow password format, plus
 programs for managing user and group accounts. The pwconv command
 converts passwords to the shadow password format. The pwunconv command
 unconverts shadow passwords and generates a passwd file (a standard
 UNIX password file). The pwck command checks the integrity of password
 and shadow files. The lastlog command prints out the last login times
 for all users. The useradd, userdel, and usermod commands are used for
 managing user accounts. The groupadd, groupdel, and groupmod commands
 are used for managing group accounts.

 ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
 ##   -MM, not -M (despite what the docs say).  Also, it might not be

 ## - Using -M directly means running the compiler twice (even worse

 ## This next piece of magic avoids the "deleted header file" problem.
 ## The problem is that when a header file which appears in a .P file
 ## is deleted, the dependency causes make to die (because there is
 ## typically no way to rebuild the header).  We avoid this by adding
 ## dummy dependencies for each header file.  Too bad gcc doesn't do
 ## this for us directly.
 ## Some versions of gcc put a space before the ':'.  On the theory
 ## that the space means something, we add a space to the output as
 ## well.  hp depmode also adds that space, but also prefixes the VPATH
 ## to the object.  Take care to not repeat it in the output.
 ## Some versions of the HPUX 10.20 sed can't process this invocation
 ## correctly.  Breaking it into two sed invocations is a workaround.

  -s            $stripprog installed files.
  -S SUFFIX     attempt to back up existing files, with suffix SUFFIX.
  -t DIRECTORY  install into DIRECTORY.
  -T            report an error if DSTFILE is a directory.
 Environment variables override the default commands:
  CHGRPPROG CHMODPROG CHOWNPROG CMPPROG CPPROG MKDIRPROG MVPROG
  RMPROG STRIPPROG
 By default, rm is invoked with -f; when overridden with RMPROG,
 it's up to you to specify -f if you want it.
 If -S is not specified, no backups are attempted.

 ABOUT shadow-login limits:
 This code is merged into shadow login program from the original LShell 2.01
 written by Joel Katz. The port and some additional features have been added
 by Cristian Gafton (gafton@sorosis.ro).
 Changes:
 	- 96/04/16
 		- {spaces,tabs} allowed within limits string
 		- Warn via syslog multiple default limits
 		- added few paragraphs to the login man page
 	- 96/04/14
 		- code merged into lmain.c --cristiang
 TODO:	- support groups in the limits file
 	  (only usernames are supported at this moment :-( )
 Setting user limits for shadow login program
 First, make a root-only-readable file (/etc/limits by default or LIMITS_FILE
 defined config.h) that describes the resource limits you wish to impose. By
 default no quotas are imposed on 'root'. In fact, there is no way to impose
 limits via this procedure to root-equiv accounts (accounts with UID 0).
 Each line describes a limit for a user in the form:
 	user LIMITS_STRING
 The LIMITS_STRING is a string of a concatenated list of resource limits.
 Each limit consists of a letter identifier followed by a numerical limit.
 The valid identifiers are:
 	A: max address space (KB)
 	C: max core file size (KB)
 	D: max data size (KB)
 	F: maximum filesize (KB)
 	M: max locked-in-memory address space (KB)
 	N: max number of open files
 	R: max resident set size (KB)
 	S: max stack size (KB)
 	T: max CPU time (MIN)
 	U: max number of processes
 	L: max number of logins for this user
 For example, L2D2048N5 is a valid LIMITS_STRING. For reading convenience,
 the following entries are equivalent:
 username L2D2048N5
 username L2 D2048 N5
 Be aware that after <username> the rest of the line is considered a limit
 string, thus comments are not allowed. A invalid limits string will be
 rejected (not considered) by the login program.
 The default entry is denoted by username '*'. If you have multiple 'default'
 entries in your LIMITS_FILE, then the last one will be used as the default
 entry.
 To completely disable limits for a user, a single dash (-) will do.
 Also, please note that all limit settings are set PER LOGIN.  They are
 not global, nor are they permanent.  Perhaps global limits will come, but
 for now this will have to do ;)

 # Login access control table.
 #
 # When someone logs in, the table is scanned for the first entry that
 # matches the (user, host) combination, or, in case of non-networked
 # logins, the first entry that matches the (user, tty) combination.  The
 # permissions field of that table entry determines whether the login will
 # be accepted or refused.
 #
 # Format of the login access control table is three fields separated by a
 # ":" character:
 #
 # 	permission : users : origins
 #
 # The first field should be a "+" (access granted) or "-" (access denied)
 # character.
 #
 # The second field should be a list of one or more login names, group
 # names, or ALL (always matches). A pattern of the form user@host is
 # matched when the login name matches the "user" part, and when the
 # "host" part matches the local machine name.
 #
 # The third field should be a list of one or more tty names (for
 # non-networked logins), host names, domain names (begin with "."), host
 # addresses, internet network numbers (end with "."), ALL (always
 # matches) or LOCAL (matches any string that does not contain a "."
 # character).
 #
 # If you run NIS you can use @netgroupname in host or user patterns; this
 # even works for @usergroup@@hostgroup patterns. Weird.
 #
 # The EXCEPT operator makes it possible to write very compact rules.
 #
 # The group file is searched only when a name does not match that of the
 # logged-in user. Only groups are matched in which users are explicitly
 # listed: the program does not look at a user's primary group id value.

 * SYNOPSIS
 *	[[gnu::malloc(erase_pass)]]
 *	char *agetpass(const char *prompt);
 *	char *agetpass_stdin();
 *
 *	void erase_pass(char *pass);
 *
 * ARGUMENTS
 *   agetpass()
 *	prompt	String to be printed before reading a password.
 *
 *   erase_pass()
 *	pass	password previously returned by agetpass().
 *
 * DESCRIPTION
 *   agetpass()
 *	This function is very similar to getpass(3).  It has several
 *	advantages compared to getpass(3):
 *
 *	- Instead of using a static buffer, agetpass() allocates memory
 *	  through malloc(3).  This makes the function thread-safe, and
 *	  also reduces the visibility of the buffer.
 *
 *	- agetpass() doesn't reallocate internally.  Some
 *	  implementations of getpass(3), such as glibc, do that, as a
 *	  consequence of calling getline(3).  That's a bug in glibc,
 *	  which allows leaking prefixes of passwords in freed memory.
 *
 *	- agetpass() doesn't overrun the output buffer.  If the input
 *	  password is too long, it simply fails.  Some implementations
 *	  of getpass(3), share the same bug that gets(3) has.
 *
 *	As soon as possible, the password obtained from agetpass() be
 *	erased by calling erase_pass(), to avoid possibly leaking the
 *	password.
 *
 *   agetpass_stdin()
 *	This function is the same as previous one (agetpass). Just the
 *	password is read from stdin and terminal is not required.
 *
 *   erase_pass()
 *	This function first clears the password, by calling
 *	explicit_bzero(3) (or an equivalent call), and then frees the
 *	allocated memory by calling free(3).
 *
 *	NULL is a valid input pointer, and in such a case, this call is
 *	a no-op.
 *
 * RETURN VALUE
 *	agetpass() returns a newly allocated buffer containing the
 *	password on success.  On error, errno is set to indicate the
 *	error, and NULL is returned.
 *
 * ERRORS
 *   agetpass()
 *	This function may fail for any errors that malloc(3) or
 *	readpassphrase(3) may fail, and in addition it may fail for the
 *	following errors:
 *
 *	ENOBUFS
 *		The input password was longer than PASS_MAX.
 *
 * CAVEATS
 *	If a password is passed twice to erase_pass(), the behavior is
 *	undefined.
