From d578b46db69d125a654f509bdc9091d84e924dc8 Mon Sep 17 00:00:00 2001 From: Gao Xiang Date: Tue, 11 Aug 2020 15:00:20 +0800 Subject: erofs: avoid duplicated permission check for "trusted." xattrs 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 --- fs/erofs/xattr.c | 2 -- 1 file changed, 2 deletions(-) (limited to 'fs/erofs/xattr.c') diff --git a/fs/erofs/xattr.c b/fs/erofs/xattr.c index c8c381eadcd6..5bde77d70852 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; -- cgit v1.2.3
