mm: require ->set_page_dirty to be explicitly wired up

2021-06-29T17:53:48Z

Remove the CONFIG_BLOCK default to __set_page_dirty_buffers and just wire that method up for the missing instances.

xattr: handle idmapped mounts

2021-01-24T13:27:17Z

When interacting with extended attributes the vfs verifies that the caller is privileged over the inode with which the extended attribute is associated. For posix access and posix default extended attributes a uid or gid can be stored on-disk. Let the functions handle posix extended attributes on idmapped mounts. If the inode is accessed through an idmapped mount we need to map it according to the mount's user namespace. Afterwards the checks are identical to non-idmapped mounts. This has no effect for e.g. security xattrs since they don't store uids or gids and don't perform permission checks on them like posix acls do.

xattr: Add __vfs_{get,set,remove}xattr helpers

2016-10-08T00:10:44Z

Right now, various places in the kernel check for the existence of getxattr, setxattr, and removexattr inode operations and directly call those operations. Switch to helper functions and test for the IOP_XATTR flag instead. Signed-off-by: Andreas Gruenbacher Acked-by: James Morris Signed-off-by: Al Viro

switch ->setxattr() to passing dentry and inode separately

2016-05-28T00:09:16Z

smack ->d_instantiate() uses ->setxattr(), so to be able to call it before we'd hashed the new dentry and attached it to inode, we need ->setxattr() instances getting the inode as an explicit argument rather than obtaining it from dentry. Similar change for ->getxattr() had been done in commit ce23e64. Unlike ->getxattr() (which is used by both selinux and smack instances of ->d_instantiate()) ->setxattr() is used only by smack one and unfortunately it got missed back then.
