* libmisc/idmapping.h: Document what the upper and lower fields
are in struct map_range.
* man/newgidmap.1.xml: Document when the gid, gidlower and count
argument are.
* man/newuidmap.1.xml: Likewise for uid, uidlower and count.
* libmisc/salt.c (shadow_random): Use long instead of size_t.
Compatibility with size_t is easier to check since it's used for
smaller numbers (salt size).
* man/login.defs.d/SUB_GID_COUNT.xml: Document that the behavior
of useradd and newusers depends on the existence of /etc/subgid.
* man/login.defs.d/SUB_UID_COUNT.xml: Likewise for /etc/subuid.
* src/useradd.c: Change message in case of find_new_sub_uids /
find_new_sub_gids failure. This complements the messages already
provided by these APIs.
* configure.in: Add configure options --enable-subordinate-ids /
--disable-subordinate-ids. Enabled by default.
* lib/prototypes.h: Include <config.h> before using its macros.
* lib/commonio.h, lib/commonio.c: Define commonio_append only when
ENABLE_SUBIDS is defined.
* lib/prototypes.h, libmisc/find_new_sub_gids.c,
libmisc/find_new_sub_uids.c: Likewise.
* lib/subordinateio.h, lib/subordinateio.c: Likewise.
* libmisc/user_busy.c: Only check if subordinate IDs are in use if
ENABLE_SUBIDS is defined.
* src/Makefile.am: Create newgidmap and newuidmap only if
ENABLE_SUBIDS is defined.
* src/newusers.c: Check for ENABLE_SUBIDS to enable support for
subordinate IDs.
* src/useradd.c: Likewise.
* src/userdel.c: Likewise.
* src/usermod.c: Likewise.
* man/Makefile.am: Install man1/newgidmap.1, man1/newuidmap.1,
man5/subgid.5, and man5/subuid.5 only if ENABLE_SUBIDS is defined.
* man/fr/Makefile.am: Install man1/newgidmap.1, man1/newuidmap.1,
man5/subgid.5, and man5/subuid.5 (not translated yet).
* man/generate_mans.mak: Add xsltproc conditionals
subids/no_subids.
* man/login.defs.d/SUB_GID_COUNT.xml: Add dependency on subids
condition.
* man/login.defs.d/SUB_UID_COUNT.xml: Likewise.
* man/usermod.8.xml: Document options for subordinate IDs and
reference subgid(5) / subuid(5) depending on the subids condition.
rlogin support is old school code, so newer C libraries drop support for
ruserok (like uClibc, optionally). But shadow doesn't build with that,
so have it check for ruserok to optionally enable rlogin.

* lib/groupmem.c (__gr_dup): Support libc which define other
fields in struct group.
* lib/pwmem.c: Likewise for struct passwd.
* lib/shadowmem.c: Likewise for struct spwd.
* lib/sgroupio.c: Apply same logic, even if this structure is
defined internally.
* libmisc/salt.c: random() max value is 2^31-1 (same as RAND_MAX
on GNU). As it is not clear whether on some systems the max value
can exceed this number and whether some systems have max values
which would be lower, we take this into account when defining the
salt size and number of rounds for SHA encrypted passwords. Higher
values are favored.
Review b10cba0e0a and 7a16f4582d:
* lib/groupio.c (merge_group_entries): Do not allocate more than
necessary (sizeof char* instead of char).
Thanks for Tomáš Mráz (alioth#313962)
* lib/groupio.c (merge_group_entries): Document that new_members
is correctly NULL terminated. (alioth:#313940)
Align previous ChangeLog entries.
* Changelog: Update documentation of 2013-07-28 mancha entry.
* lib/prototypes.h, lib/encrypt.c: Update splint marker,
pw_encrypt can return NULL.
* lib/encrypt.c: Fix outdated statement on GNU crypt.
* src/chgpasswd.c: Improve diagnostic to user when pw_encrypt
fails and use fail_exit() instead of exit().
* src/chpasswd.c: Likewise.
* src/newusers.c: Likewise.
* src/passwd.c: Likewise when new password is encrypted.
* src/newgrp.c: Improve diagnostic to user and syslog when
pw_encrypt fails. Do not apply 1s penalty as this is not an
invalid password issue.
* src/passwd.c: Likewise when password is checked.
* libmisc/setupenv.c: xstrdup the static char* temp_pw_dir /
temp_pw_shell. That way we can continue to use pw_free() without
segving. Thanks to Serge Hallyn for the patch.
a salt that violates specs. On Linux, crypt() also fails with
DES/MD5 salts in FIPS140 mode. Rather than exit() on NULL returns
we send them back to the caller for appropriate handling.
