ranges.
2013-08-15 Nicolas François <nicolas.francois@centraliens.net>
* libmisc/find_new_sub_gids.c: Remove dead code.
find_new_sub_gids() is always called with *range_count set to 0.
It's more difficult to keep the subordinate GIDs and UIDs
synchronized, than for the user's UID/GId because the count of
subordinate IDs may differ.
* libmisc/find_new_sub_uids.c: Likewise.
* lib/subordinateio.h, lib/subordinateio.c: Remove APIs that are
no more needed: is_sub_uid_range_free(), is_sub_gid_range_free(),
is_range_free().
2013-08-13 Nicolas François <nicolas.francois@centraliens.net>
* configure.in: Check if sizeof uid_t and gid_t is larger than 32
bit to support subordinate IDs.
2013-08-13 Nicolas François <nicolas.francois@centraliens.net>
* lib/subordinateio.c: Avoid dead branches.
* lib/subordinateio.c: Add schematics with ranges to help reviews.

integers to booleans.

Debian#677812
2013-08-13 Nicolas François <nicolas.francois@centraliens.net>
* lib/subordinateio.c: Fix count for ranges truncated in
remove_range().
2013-08-13 Nicolas François <nicolas.francois@centraliens.net>
* src/su.c: Terminate the child (if needed) before closing the PAM
session. This is probably more correct, and avoid reporting
termination from signals possibly sent by PAM modules (e.g. former
versions of pam_systemd). Debian#670132
2013-08-13 Nicolas François <nicolas.francois@centraliens.net>
* src/su.c: When a SIGTSTP is caught, reset caught to 0. There is
no need to kill the child in such case after su is resumed. This
remove the "Session terminated, terminating shell...
...terminated." messages in such case.
2013-08-13 Nicolas François <nicolas.francois@centraliens.net>
* man/newgidmap.1.xml: Document the checks performed before
setting the mapping in /proc.
* man/newuidmap.1.xml: Likewise.
2013-08-13 Nicolas François <nicolas.francois@centraliens.net>

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.
2013-08-13 Nicolas François <nicolas.francois@centraliens.net>
* 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).
2013-08-13 Nicolas François <nicolas.francois@centraliens.net>
* lib/groupmem.c: Add splint annotations. The added memset makes
splint think data was allocated.
* lib/pwmem.c: Likewise.
* lib/sgroupio.c: Likewise.
* lib/shadowmem.c: Likewise.
2013-08-13 Nicolas François <nicolas.francois@centraliens.net>
* 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.
2013-08-13 Nicolas François <nicolas.francois@centraliens.net>
* 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.
2013-08-13 Nicolas François <nicolas.francois@centraliens.net>
* lib/subordinateio.c: Fix handling of boundaries.
* libmisc/find_new_sub_uids.c: Likewise.
* libmisc/find_new_sub_gids.c: Likewise.
2013-08-12 Nicolas François <nicolas.francois@centraliens.net>
* lib/subordinateio.c: Fix removal of ranges. The database needs
to be marked as changed or commonio_close will discard any change.
2013-08-11 Nicolas François <nicolas.francois@centraliens.net>
* man/newusers.8.xml: Include documentation of SUB_GID_MIN,
SUB_GID_MAX, SUB_GID_COUNT, SUB_UID_MIN, SUB_UID_MAX,
SUB_UID_COUNT.
* man/useradd.8.xml: Likewise.
* man/usermod.8.xml: Likewise.
* man/newusers.8.xml: Document usage of /etc/subgid /etc/subuid.
* man/useradd.8.xml: Likewise.

concatenated 2 lines was correct.
2013-08-05 Nicolas François <nicolas.francois@centraliens.net>
* 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.
2013-08-04 Nicolas François <nicolas.francois@centraliens.net>

2013-07-28 mancha <mancha1@hush.com>
* lib/encrypt.c (pw_encrypt): crypt() in glibc/eglibc 2.17 now
fails if passed 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 (instead of exiting). Closes: alioth#314234
* lib/pwauth.c: Handle NULL return from pw_crypt(), return non
zero (as in case of failure).
* libmisc/valid.c: Likewise.
* src/chgpasswd.c: Handle NULL return from pw_crypt(), report
crypt error to stderr and exit.
* src/chpasswd.c: Likewise.
* src/gpasswd.c: Likewise.
* src/newusers.c: Likewise.
* src/passwd.c: Likewise when new password is encrypted.
* src/newgrp.c: Handle NULL return from pw_crypt(), report crypt
error to stderr and syslog and return to report unchanged
password.
* src/passwd.c: Likewise when password is checked.
2013-07-28 Christian Perrier <christian@perrier.eu.org>
* configure.in: Prepare for next point release 4.2.
* if using the static char* for pw_dir, strdup it so
pw_free() can be used. (Closes: Debian#691459, alioth#313957)
* Kill the child process group, rather than just the
immediate child; this is needed now that su no
longer starts a controlling terminal when not running an
interactive shell (closes: Debian#713979)
Thansk to Colin Watson for the patch.

shadow-4.1.5.1 -> shadow-4.2 UNRELEASED
*** general
* Handle libc whose crypt() returns NULL when passed a salt that
violates specs or system requirements (e.g. FIPS140). This is needed
with glibc/eglibc 2.17 for tools checking passwords (passwd (non PAM
enabled) or newgrp), and for tools generating encrypted passwords
(chgpasswd, chpasswd, or gpasswd when non PAM enabled or when a fixed
crypt method is requested on the command line, and newusers, or passwd
in their non PAM enabled versions)
* Fix segfault when reading groups split on multiple lines. This impacts
most user/group management tools when MAX_MEMBERS_PER_GROUP is set.
- su
* When su receives a signal (SIGTERM, or SIGINT/SIGQUIT in non
interactive mode), kill the child process group, rather than just the
immediate child.
* Fix segmentation faults for users without a proper home or shell in
their passwd entries.
- login
* Fix segmentation faults for users without a proper home or shell in
their passwd entries.
*** documentation
* Fixed useradd man page (--home-dir option, instead of --home).
*** translation
* Updated Russian translation.
* Updated German man pages translation.
* Fixed gshadow Japanese man page translation.

# Output a system dependent set of variables, describing how to set the

# Copyright 1996-2006 Free Software Foundation, Inc.
# Taken from GNU libtool, 2001
# Originally by Gordon Matzigkeit <gord@gnu.ai.mit.edu>, 1996

# This file is free software; the Free Software Foundation gives
# unlimited permission to copy and/or distribute it, with or without
# modifications, as long as this notice is preserved.
#
# The first argument passed to this file is the canonical host specification,
# CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
# or
# CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
# The environment variables CC, GCC, LDFLAGS, LD, with_gnu_ld
# should be set by the caller.
#
# The set of defined variables is at the end of this script.
# Known limitations:
# - On IRIX 6.5 with CC="cc", the run time search patch must not be longer
# than 256 bytes, otherwise the compiler driver will dump core. The only
# known workaround is to choose shorter directory names for the build
# directory and/or the installation directory.
# All known linkers require a `.a' archive for static linking (except MSVC,
# which needs '.lib').

## There are various ways to get dependency output from gcc. Here's

## - Don't want to use -MD because we'd like the dependencies to end
## up in a subdir. Having to rename by hand is ugly.
## (We might end up doing this anyway to support other compilers.)
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
## -MM, not -M (despite what the docs say).
## - Using -M directly means running the compiler twice (even worse
## than renaming).

## 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 the HPUX 10.20 sed can't process this invocation
