+Subject: [PATCH] libapparmor: add missing include for `socklen_t`
+
+While `include/sys/apparmor.h` makes use of `socklen_t`, it doesn't
+include the `<sys/socket.h>` header to make its declaration available.
+While this works on systems using glibc via transitive includes, it
+breaks compilation on musl libc.
+
+Fix the issue by including the header.

+Subject: [PATCH] libapparmor: add `aa_features_new_from_file` to public
+ symbols
+
+With AppArmor release 3.0, a new function `aa_features_new_from_file`
+was added, but not added to the list of public symbols. As a result,
+it's not possible to make use of this function when linking against
+libapparmor.so.
+
+Fix the issue by adding it to the symbol map.

+Subject: [PATCH] libapparmor: add _aa_asprintf to private symbols
+
+While `_aa_asprintf` is supposed to be of private visibility, it's used
+by apparmor_parser and thus required to be visible when linking. This
+commit thus adds it to the list of private symbols to make it available
+for linking in apparmor_parser.
