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.
Fail if the feature is requested but the library (or
header file) could not be found. If nothing is specified, enable
the feature only if we can find the library (or header file).
and "pwauth.h" only when compiled without PAM support.
* src/chfn.c, src/chsh.c: Do not include <shadow.h>
* lib/commonio.c: Do not include <shadow.h>. Do not include
<pwd.h>. Include "nscd.h" instead of <nscd.h>.
* configure.in: Do not check if shadow.h exist, but make sure it
exists.
* libmisc/pwdcheck.c, src/chfn.c, src/chsh.c, lib/defines.h,
lib/shadowmem.c, lib/shadowio.c, lib/commonio.c:
HAVE_SHADOW_H is no more needed (shadow.h should always exist).
man/po/POTFILES.in, man/Makefile.am: Generate the PO files for the
manpages in the man/po directory (instead of man/<lang>). Use a
Makefile.in.in based on gettext's one. This ensure that the PO are
generated before being used in the <lang> directories.
* man/generate_mans.mak, man/generate_translations.mak,
man/Makefile.am: New makefile for the generation of manpages from
XML (generate_mans.mak). This avoid duplicate chunks in
generate_translations.mak and Makefile.am
* man/de/de.po, man/fr/fr.po, man/it/it.po, man/pl/pl.po,
man/ru/ru.po, man/sv/sv.po: Moved to...
* man/po/de.po, man/po/fr.po, man/po/it.po, man/po/pl.po,
man/po/ru.po, man/po/sv.po: ... here.
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).
generation of manpages.
* man/generate_translations.mak: Added pam/no_pam condition (like
in man/Makefile.am).
* man/Makefile.am, man/generate_translations.mak: Added
gshadow/no_gshadow condition.
* man/gpasswd.1.xml: Use the gshadow/no_gshadow condition to
change the manpage depending on the shadow group support.
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,
libmisc/addgrps.c, libmisc/myname.c, libmisc/rlogin.c,
libmisc/pwdcheck.c, src/newgrp.c, src/login_nopam.c,
src/userdel.c, src/lastlog.c, src/grpck.c, src/gpasswd.c,
src/newusers.c, src/chpasswd.c, src/chfn.c, src/groupmems.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.
