UBI: hide EBA internals

2016-10-02T20:48:14Z

Create a private ubi_eba_table struct to hide EBA internals and provide helpers to allocate, destroy, copy and assing an EBA table to a volume. Now that external EBA users are using helpers to query/modify the EBA state we can safely change the internal representation, which will be needed to support the LEB consolidation concept.

ubi: Fix early logging

2016-07-29T21:31:55Z

We cannot use ubi_* logging functions before the UBI object is initialized. Cc: Fixes: 3260870331 ("UBI: Extend UBI layer debug/messaging capabilities") Signed-off-by: Richard Weinberger

ubi: Fix race condition between ubi device creation and udev

2016-07-29T21:30:28Z

Install the UBI device object before we arm sysfs. Otherwise udev tries to read sysfs attributes before UBI is ready and udev rules will not match. Cc: Signed-off-by: Iosif Harutyunov [rw: massaged commit message] 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 open_mtd_by_chdev() to use of vfs_stat()"

2016-06-14T08:51:42Z

This reverts commit 87f15d4add758fb7fc76655721af94be57a4c17d. vfs_stat() can only be used on user supplied buffers. Cc: Al Viro Signed-off-by: Richard Weinberger

UBI: Add ro-mode sysfs attribute

2016-05-24T13:15:26Z

On serious situations, UBI may detect serious device corruption, and switch to read-only mode to protect the data and allow debugging. This commit exposes this ro-mode on sysfs, so it can be obtained by userspace tools. Signed-off-by: Ezequiel Garcia Signed-off-by: Richard Weinberger

UBI: Use static class and attribute groups

2015-06-02T11:16:25Z

This patch cleans up the manual device_create_file() or class_create_file() calls by replacing with static attribute groups. It simplifies the code and also avoids the possible races between the device/class registration and sysfs creations. For the simplification, also make ubi_class a static instance with initializers, too. Amend a bit by Hujianyang.
