Subject: [PATCH] Fix errors with -Werror=format-security
Recent versions of the Fedora build system treat format-security
warnings as errors, resulting in failure to build. This patch
ensures that appropriate format strings are present.

check that case, also to avoid compiler warnings like:

Subject: [PATCH 10/12] files.c: Init char *name to NULL
Merges:
https://pagure.io/libuser/issue/27
This is mostly to silence coverity warnings. "enum lu_entity_type" has
three values and several places in the code follow logic as:
char *name;
if ent->type == user:
name = foo()
if ent->type == group
name = bar()
g_assert(name != NULL)
it shouldn't be possible for ent->type to be anything else but in the
odd case it is, initializing name to NULL will ensure that name will be
still NULL after the code falls through the conditions and at least the
behaviour is defined.

Subject: [PATCH 2/5] lib/util.c: Use crypt_gensalt(), if available in libcrypt.
Most Linux distributions, including Fedora and RHEL 8, are shipping
with libxcrypt >= 4.0.
Since that version of libxcrypt the provided family of crypt_gensalt()
functions are able to use automatic entropy drawn from secure system
ressources, like arc4random(), getentropy() or getrandom().
Anyways, the settings generated by crypt_gensalt() are always
guaranteed to works with the crypt() function.
Using crypt_gesalt() is also needed to make proper use of newer
hashing methods, like yescrypt, provided by libxcrypt.

From 29d9996dd200916db888d41196f87609bce329ff Mon Sep 17 00:00:00 2001
From: Petr Lautrbach <plautrba@redhat.com>
Date: Apr 07 2020 11:55:38 +0000
Subject: Do not use deprecated flask.h and av_permissions.h
selinux/flask.h and selinux/av_permissions.h will be completely dropped in the
next SELinux release.
Use string_to_security_class() and string_to_av_perm() to get class and
permission values. The original hardcoded values could be invalid and are
deprecated as the whole flask.h and av_permissions.h header files.
Fixes: https://pagure.io/libuser/issue/44
