From 95daf621291c1203d9d2cebb119d0cd2d53898f9 Mon Sep 17 00:00:00 2001 From: Gao Xiang Date: Tue, 11 Aug 2020 15:00:20 +0800 Subject: [PATCH] erofs: avoid duplicated permission check for "trusted." xattrs commit d578b46db69d125a654f509bdc9091d84e924dc8 upstream. Don't recheck it since xattr_permission() already checks CAP_SYS_ADMIN capability. Just follow 5d3ce4f70172 ("f2fs: avoid duplicated permission check for "trusted." xattrs") Reported-by: Hongyu Jin [ Gao Xiang: since it could cause some complex Android overlay permission issue as well on android-5.4+, it'd be better to backport to 5.4+ rather than pure cleanup on mainline. ] Cc: # 5.4+ Link: https://lore.kernel.org/r/20200811070020.6339-1-hsiangkao@redhat.com Reviewed-by: Chao Yu Signed-off-by: Gao Xiang Signed-off-by: Greg Kroah-Hartman --- fs/erofs/xattr.c | 2 -- 1 file changed, 2 deletions(-) diff --git a/fs/erofs/xattr.c b/fs/erofs/xattr.c index b766c3ee5fa8..503bea20cde2 100644 --- a/fs/erofs/xattr.c +++ b/fs/erofs/xattr.c @@ -473,8 +473,6 @@ static int erofs_xattr_generic_get(const struct xattr_handler *handler, return -EOPNOTSUPP; break; case EROFS_XATTR_INDEX_TRUSTED: - if (!capable(CAP_SYS_ADMIN)) - return -EPERM; break; case EROFS_XATTR_INDEX_SECURITY: break;
