Created attachment 437106 [details, diff] Patch from SF thread. musl implements realpath through analyzing the proc filesystem grsec adds proc restrictions which blocks use of realpath in some cases. As a result, FUSE is broken on musl with a grsec kernel. The thread argues that the provided patch causes a security issue. See this thread: https://sourceforge.net/p/fuse/mailman/message/33378384/

this is not PaX code but grsec so better CC spender on it ;).
