+Subject: [PATCH] Allow negative uids/gids in PolkitUnixUser and Group objects
+
+(uid_t) -1 is still used as placeholder to mean "unset". This is OK, since
+there should be no users with such number, see
+https://systemd.io/UIDS-GIDS#special-linux-uids.
+
+(uid_t) -1 is used as the default value in class initialization.
+
+When a user or group above INT32_MAX is created, the numeric uid or
+gid wraps around to negative when the value is assigned to gint, and
+polkit gets confused. Let's accept such gids, except for -1.
+
+A nicer fix would be to change the underlying type to e.g. uint32 to
+not have negative values. But this cannot be done without breaking the
+API, so likely new functions will have to be added (a
+polkit_unix_user_new variant that takes a unsigned, and the same for
+_group_new, _set_uid, _get_uid, _set_gid, _get_gid, etc.). This will
+require a bigger patch.
+
+Fixes https://gitlab.freedesktop.org/polkit/polkit/issues/74.
