+ * pwdauth.c - program to verify a given username/password pair.
+ *
+ * Run it with username in argv[1] (may be omitted - default is the
+ * current user), and send it the password over a pipe on stdin.
+ * Exit status: 0 - correct password, 1 - wrong password, >1 - other
+ * errors.  For use with shadow passwords, this program should be
+ * installed setuid root.
+ *
+ * This can be used, for example, by xlock - you don't have to install
+ * this large and complex (== possibly insecure) program setuid root,
+ * just modify it to run this simple program to do the authentication.
+ *
+ * Recent versions (xlockmore-3.9) are cleaner, and drop privileges as
+ * soon as possible after getting the user's encrypted password.
+ * Using this program probably doesn't make it more secure, and has one
+ * disadvantage: since we don't get the encrypted user's password at
+ * startup (but at the time the user is authenticated), it is not clear
+ * how we should handle errors (like getpwnam() returning NULL).
+ * - fail the authentication?  Problem: no way to unlock (other than kill
+ *   the process from somewhere else) if the NIS server stops responding.
+ * - succeed and unlock?  Problem: it's too easy to unlock by unplugging
+ *   the box from the network and waiting until NIS times out...

+##   -MM, not -M (despite what the docs say).  Also, it might not be
+##   supported by the other compilers which use the 'gcc' depmode.
+## - 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.

-# Build & install
-
-The following page explains how to build and install the shadow project.
-Additional information on how to do this in a container environment is provided
-at the end of the page.
-
-## Local
-
-### Dependency installation
-
-This projects depends on other software packages that need to be installed
-before building it. We recommend using the dependency installation commands
-provided by the distributions to install them. Some examples below.
-
-Debian:
-```
-apt-get build-dep shadow
-```
-
-Fedora:
-```
-dnf builddep shadow-utils
-```
-
-An alternative would be to take a look at the CI workflow [file](../../.github/workflows/runner.yml)
-and get the package names from there. This has the advantage that it
-also includes new dependencies needed for the development version
-which might have not been present in the last release.
-
-### Configure
-
-The first step is to configure it. You can use the
-`autogen.sh` script provided by the project. Example:
-
-```
-./autogen.sh --without-selinux --enable-man --with-yescrypt
-```
-
-### Build
-
-The next step is to build the project:
-
-```
-make -j4
-```
-
-### Install
-
-The last step is to install it. We recommend avoiding this step and using a
-disposable system like a VM or a container instead.
-
-```
-make install
-```
-
-## Containers
-
-Alternatively, you can use any of the preconfigured container images builders
-to build and install shadow.
-
-You can either generate a single image by running the following command from
-the root folder of the project (i.e. Alpine):
-
-```
-docker build -f share/containers/alpine.dockerfile . --output build-out/alpine
-```
-
-Or generate all of the images with the `container-build.sh` script, as if you
-were running some of the CI checks locally:
-
-```
-share/container-build.sh
-```

-# Continuous Integration (CI)
-
-Shadow runs a CI workflow every time a pull-request (PR) is updated. This
-workflow contains several checks to assure the quality of the project, and
-only pull-requests with green results are merged.
-
-## Build & install
-
-The project is built & installed on Ubuntu, Alpine, Debian and Fedora. The last
-three distributions are built & installed on containers, and the workflow can
-be triggered locally by following the instructions specified in the
-[Build & install](build_install.md#containers) page.
-
-## System tests
-
-The project is tested on Ubuntu. For that purpose it is built & installed in
-this distribution in a VM. You can run this step locally by following the
-instructions provided in the [Tests](tests.md#system-tests) page.
-
-## Static code analysis
-
-C and shell static code analysis is also executed. For that purpose
-[CodeQL](https://codeql.github.com/) and
-[Differential ShellCheck](https://github.com/marketplace/actions/differential-shellcheck)
-are used.

-# Coding style
-
-* For a general guidance refer to the
-[Linux kernel coding style](https://www.kernel.org/doc/html/latest/process/coding-style.html)
-
-* Patches that change the existing coding style are not welcome, as they make
-downstream porting harder for the distributions
-
-## Indentation
-
-Tabs are preferred over spaces for indentation. Loading the `.editorconfig`
-file in your preferred IDE may help you configure it.

-# Introduction
-
-## Git and Github
-
-We recommend you to get familiar with the
-[git](https://guides.github.com/introduction/git-handbook) and
-[Github](https://guides.github.com) workflows before posting any changes.
-
-### Set up in a nut shell
-
-The following steps describe the process in a nut shell to provide you a basic
-template:
-
-* Create an account on [GitHub](https://github.com)
-* Fork the [shadow repository](https://github.com/shadow-maint/shadow)
-* Clone the shadow repository
-
-```
-git clone https://github.com/shadow-maint/shadow.git
-```
-
-* Add your fork as an extra remote
-
-```
-git remote add $ghusername git@github.com:$ghusername/shadow.git
-```
-
-* Setup your name contact e-mail that you want to use for the development
-
-```
-git config user.name "John Smith"
-git config user.email "john.smith@home.com"
-```
-
-**Note**: this will setup the user information only for this repository. You
-can also add `--global` switch to the `git config` command to setup these
-options globally and thus making them available in every git repository.
-
-* Create a working branch
-
-```
-git checkout -b my-changes
-```
-
-* Commit changes
-
-```
-vim change-what-you-need
-git commit -s
-```
-
-Check
-[the kernel patches guide](https://www.kernel.org/doc/html/v4.14/process/submitting-patches.html#describe-your-changes)
-to get an idea on how to write a good commit message.
-
-* Push your changes to your GitHub repository
-
-```
-git push $ghusername my-changes --force
-```
-
-* Open a Pull Request against shadow project by clicking on the link provided
-in the output of the previous step
-
-* Make sure that all Continuous Integration checks are green and wait review
-
-## Internal guidelines
-
-Additionally, you should also check the following internal guidelines to
-understand the project's development model:
-
-* [Build & install](build_install.md)
-* [Coding style](coding_style.md)
-* [Tests](tests.md)
-* [Continuous Integration](CI.md)
-* [Releases](releases.md)
-* [License](license.md)

-# License
-
-All new source code committed to the shadow project is assumed to be made
-available under the [BSD-3-Clause](../../COPYING) license unless the submitter
-specifies another license at that time. The shadow maintainers reserve the
-right to refuse a submission if the license is deemed incompatible with the
-goals of the project.

-# Releases
-
-The shadow project doesn't follow any specific timeline to release new software
-versions. Usually, they are released when a major milestone is finished.
-
-Released source code, alongside the release notes, are provided in the
-[release Github page](https://github.com/shadow-maint/shadow/releases).
@@ -1,18 +0,0 @@
-# Tests
-
-Currently, shadow only provides system tests.
-
-## System tests
-
-These type of tests are written in shell. Unfortunately, the testing framework
-is tightly coupled to the Ubuntu distribution and it can only be run in this
-distribution. Besides, if anything fails during the execution the system can
-be left in an unstable state. Taking that into account you shouldn't run this
-workflow in your host machine, we recommend to use a disposable system like a
-VM or a container instead.
-
-You can execute system tests by running:
-
-```
-cd tests && ./run_all`.

- * SYNOPSIS
- *	[[gnu::malloc(erase_pass)]]
- *	char *agetpass(const char *prompt);
- *
- *	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.
- *
- *   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.
