ubi: Do not drop UBI device reference before using

2019-12-05T14:34:23Z

[ Upstream commit e542087701f09418702673631a908429feb3eae0 ] The UBI device reference is dropped but then the device is used as a parameter of ubi_err. The bug is introduced in changing ubi_err's behavior. The old ubi_err does not require a UBI device as its first parameter, but the new one does.

UBI: provide an helper to check whether a LEB is mapped or not

2016-10-02T20:48:14Z

This is part of the process of hiding UBI EBA's internal to other part of the UBI implementation, so that we can add new information to the EBA table without having to patch different places in the UBI code. Signed-off-by: Boris Brezillon Signed-off-by: Richard Weinberger

UBI: add an helper to check lnum validity

ubi_leb_valid() is here to replace the lnum < 0 || lnum >= vol->reserved_pebs checks. Signed-off-by: Boris Brezillon Signed-off-by: Richard Weinberger

ubi: Don't bypass ->getattr()

2016-06-14T08:51:42Z

Directly accessing inode fields bypasses ->getattr() and can cause problems when the underlying filesystem does not have the default ->getattr() implementation. So instead of obtaining the backing inode via d_backing_inode() use vfs_getattr() and obtain what we need from the kstat struct. Cc: Al Viro Reported-by: Al Viro Signed-off-by: Richard Weinberger

Revert "mtd: switch ubi_open_volume_path() to vfs_stat()"

2016-06-14T08:51:42Z

This reverts commit 322ea0bbf3003df17b6253f76e572c37d79a6810. vfs_stat() can only be used on user supplied buffers. UBI's kapi.c is the API to the kernel and therefore vfs_stat() is inappropriate. This solves the problem that mounting any UBIFS will immediately fail with -EINVAL. Cc: Al Viro Signed-off-by: Richard Weinberger

UBI: Add initial support for scatter gather

2015-01-28T15:04:26Z

Adds a new set of functions to deal with scatter gather. ubi_eba_read_leb_sg() will read from a LEB into a scatter gather list. The new data structure struct ubi_sgl will be used within UBI to hold the scatter gather list itself and metadata to have a cursor within the list.
