From e45b2546e23c2d10f8585063a15c745a7603fac9 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Fri, 4 May 2018 11:47:28 -0500 Subject: fuse: Ensure posix acls are translated outside of init_user_ns Ensure the translation happens by failing to read or write posix acls when the filesystem has not indicated it supports posix acls. This ensures that modern cached posix acl support is available and used when dealing with posix acls. This is important because only that path has the code to convernt the uids and gids in posix acls into the user namespace of a fuse filesystem. Signed-off-by: "Eric W.
