-Subject: [PATCH] libapparamor: Define a portable version of gnu basename
-
-Since musl 1.2.5, basename(3) prototype is only provided in libgen.h
-(as mandated by POSIX) and not in strings.h. Also there is a major
-difference between the gnu basename and the one defined in libgen.h,
-the latter modify the argument string making them incompatible.
-
-Fix this by defining a portable version of basename using strchr.
-
-Upstream: https://gitlab.com/apparmor/apparmor/-/commit/7fb040bde69ebdfce48cf1a01c1a62fd4f8eef0a
