1882c66bda configure.ac: Default to max group name length of 32
This used to be 16 for historical reasons but these days basically every
distro configures --with-group-name-max-length=32 to make it match the
max Linux username length, make it default.

fd5945e533 Use 'void' instead of 'RETSIGTYPE'. Use 'sighandler_t' too.
C89 and POSIX.1-2001 define signal(2) as returning a pointer to a
function returning 'void'.  K&R C signal(2) signature is obsolete.
Use 'void' directly.

Also, instead of writing the function pointer type explicitly, use
POSIX's 'sighandler_t'.

POSIX.1-2001 defines 'struct dirent' in <dirent.h>.  It replaces
the old 'struct direct' found in BSDs.  All of the systems that I
checked (including FreeBSD, NetBSD, and OpenBSD), now provide
<dirent.h> with 'struct dirent', as mandated by POSIX.

Since autoconf first checks <dirent.h> and only if it's missing it
checks other header files, it's clear that it will always find
<dirent.h>, so let's simplify.

GNU autoconf documentation declares this macro as obsolescent, and
acknowledges that all current systems with directory libraries
have <dirent.h>:

4e1afcd662 Assume STDC_HEADERS will always be defined
We're in 2021.  C89 is everywhere; in fact, there are many other
assumptions in the code that wouldn't probably hold on
pre-standard C environments.  Let's simplify and assume that C89
is available.

The specific assumptions are that:
- <string.h>, and <stdlib.h> are available
- strchr(3), strrchr(3), and strtok(3) are available
- isalpha(3), isspace(3), isdigit(3), and isupper(3) are available

I think we can safely assume we have all of those.

libmisc/salt.c: Use secure system ressources to obtain random bytes.
In a previous commit we introduced /dev/urandom as a source to obtain
random bytes from.  This may not be available on all systems, or when
operating inside of a chroot.

Almost all systems provide functions to obtain random bytes from
secure system ressources.  Thus we should prefer to use these, and
fall back to /dev/urandom, if there is no such function present, as
a last resort.

3d670ba7ed nss/libsubid: simplify the ranges variable for list_owner_ranges
Following alexey-tikhonov's suggestion.

Since we've dropped the 'owner' field in the data returned for
get_subid_ranges, we can just return a single allocated array of
simple structs.  This means we can return a ** instead of ***, and
we can get rid of the subid_free_ranges() helper, since the caller
can just free() the returned data.

8492dee663 subids: support nsswitch
Closes #154

When starting any operation to do with subuid delegation, check
nsswitch for a module to use.  If none is specified, then use
the traditional /etc/subuid and /etc/subgid files.

Currently only one module is supported, and there is no fallback
to the files on errors.  Several possibilities could be considered:

1. in case of connection error, fall back to files
2. in case of unknown user, also fall back to files

etc...

When non-files nss module is used, functions to edit the range
are not supported.  It may make sense to support it, but it also
may make sense to require another tool to be used.

libsubordinateio also uses the nss_ helpers.  This is how for instance
lxc could easily be converted to supporting nsswitch.

Add a set of test cases, including a dummy libsubid_zzz module.  This
hardcodes values such that:

'ubuntu' gets 200000 - 300000
'user1' gets 100000 - 165536
'error' emulates an nss module error
'unknown' emulates a user unknown to the nss module
'conn' emulates a connection error ot the nss module

Changes to libsubid:

Change the list_owner_ranges api: return a count instead of making the array
null terminated.

This is a breaking change, so bump the libsubid abi major number.

Rename free_subuid_range and free_subgid_range to ungrant_subuid_range,
because otherwise it's confusing with free_subid_ranges which frees
    memory.

Run libsubid tests in jenkins

Switch argument order in find_subid_owners

Move the db locking into subordinateio.c

0a7888b1fa Create a new libsubid
Closes #154

Currently this has three functions: one which returns the
list of subuid ranges for a user, one returning the subgids,
and one which frees the ranges lists.

I might be mistaken about what -disable-man means;  some of
the code suggests it means just don't re-generate them, but
not totally ignore them.  But that doesn't seem to really work,
so let's just ignore man/ when -disable-man.

Remove --disable-shared.  I'm not sure why it was there, but it stems
from long, long ago, and I suspect it comes from some ancient
toolchain bug.

Create a tests/run_some, a shorter version of run_all.  I'll
slowly add tests to this as I verify they work, then I can
work on fixing the once which don't.

Also, don't touch man/ if not -enable-man.

Changelog:
	Apr 22: change the subid list api as recomended by Dan Walsh.
	Apr 23: implement get_subid_owner
	Apr 24: implement range add/release
	Apr 25: finish tests and rebase

66b7bc0dcf Don't auto-enable ACCT_TOOLS_SETUID if PAM is detected
Here's a sad story:

* 70971457 is merged into shadow, allowing newgidmap/newuidmap to be
installed with file caps rather than setuid.
* https://bugs.archlinux.org/task/63248 is filed to take advantage of
this.
* The arch maintainer of the 'shadow' package notices that this doesn't
work, and submits a pull request to fix this in shadow.
* edf7547ad5 is merged, fixing the post install hooks.

The problem here is that distros have been building shadow with PAM for
O(years), but the install hooks have silently failed due to the
combination of the directory mismatch (suidubins vs suidsbins) and later
success with setuid'ing newgidmap/newuidmap.

With the install hooks fixed, those of us (Arch[1] and Gentoo[2] so far)
who never built shadow explicitly with --enable-account-tools-setuid are
now getting setuid account tools, and don't have PAM configuration
suitable for use with setuid account management tools.

It's entirely unclear to me why you'd want this, but I assume there's
some reason out there for it existing. Regardless, setuid binaries are
dangerous and shouldn't be enabled by default without good reason.

newuidmap/newgidmap: install with file capabilities
do not install newuidmap/newgidmap as suid binaries.  Running these
tools with the same euid as the owner of the user namespace to
configure requires only CAP_SETUID and CAP_SETGID instead of requiring
CAP_SYS_ADMIN when it is installed as a suid binary.

4aaf05d72e Flush sssd caches in addition to nscd caches
Some distributions, notably Fedora, have the following order of nsswitch
modules by default:
    passwd: sss files
    group:  sss files

The advantage of serving local users through SSSD is that the nss_sss
module has a fast mmapped-cache that speeds up NSS lookups compared to
accessing the disk an opening the files on each NSS request.

Traditionally, this has been done with the help of nscd, but using nscd
in parallel with sssd is cumbersome, as both SSSD and nscd use their own
independent caching, so using nscd in setups where sssd is also serving
users from some remote domain (LDAP, AD, ...) can result in a bit of
unpredictability.

More details about why Fedora chose to use sss before files can be found
on e.g.:
    https://fedoraproject.org//wiki/Changes/SSSDCacheForLocalUsers
or:
    https://docs.pagure.org/SSSD.sssd/design_pages/files_provider.html

Now, even though sssd watches the passwd and group files with the help
of inotify, there can still be a small window where someone requests a
user or a group, finds that it doesn't exist, adds the entry and checks
again. Without some support in shadow-utils that would explicitly drop
the sssd caches, the inotify watch can fire a little late, so a
combination of commands like this:
    getent passwd user || useradd user; getent passwd user
can result in the second getent passwd not finding the newly added user
as the racy behaviour might still return the cached negative hit from
the first getent passwd.

This patch more or less copies the already existing support that
shadow-utils had for dropping nscd caches, except using the "sss_cache"
tool that sssd ships.

Support systems that only have utmpx
This allows shadow-utils to build on systems like Adélie, which have no
<utmp.h> header or `struct utmp`.  We use a <utmpx.h>-based daemon,
utmps[1], which uses `struct utmpx` only.

Tested both `login` and `logoutd` with utmps and both work correctly.

6e91297fa2 enable silent build output by default
Enable the automake feature to produce silent output by default.
When compiling code, we now see things like:
$ make
  CC       addgrps.o
  CC       age.o
  CC       audit_help.o
...

This can be disabled via configure's --disable-silent-rules or
by passing V=1 to make.

Custom output (like in the man subdirs) don't (yet) respect this
feature.  More work will be needed to clean those up.

e33cb8ae12 switch bz2 dist to xz
Since xz is fairly common nowadays, and is typically smaller/faster than
bzip2 for people to decompress, switch shadow over too.  We also merge
the two init locations into configure.ac to match newer autotools style.

The min automake version is bumped to 1.11 too since that's when xz was
released.

84f0ae00d2 configure: avoid deprecated AC_INIT/AM_INIT_AUTOMAKE invocation
The autoconf/automake guys want AC_INIT to be passed the details of the
package directly rather than going through AM_INIT_AUTOMAKE.  Update them
both to use the newer style.

This also allows us to pass in contact details for the project.

We set the minimum autoconf version to 2.64 as that's the first one to
support passing the homepage URL in to AC_INIT.  That's a pretty old
release by now, so it shouldn't be a problem.
