ubi-utils: add wear-leveling threshold parameter to ubiattach

2026-08-03T05:42:07+00:00

Add wl_threshold support end-to-end: expose the kernel's wear-leveling threshold via a new --wl-threshold / -w option in ubiattach, plumb it through libubi, and define it by replacing 4 bytes of padding in struct ubi_attach_req. Valid range is 2-65536; 0 means use the kernel default. Signed-off-by: Ran Hongyun Signed-off-by: David Oberhollenzer

mtd-utils: don't include features.h

2026-08-03T05:42:02+00:00

This is an internal header that's already included with others. Signed-off-by: Rosen Penev Signed-off-by: David Oberhollenzer

Import a more recent version of libiniparser

2024-12-17T12:51:35+00:00

We use a vendored library for parsing ini files. Our copy of this library has not been updated since 2007. This commit imports the recent version of the ini parsing library from upstream source at https://gitlab.com/iniparser/iniparser Signed-off-by: David Oberhollenzer

ubifs-utils: Move ubifs-media.h in libubifs

2024-11-11T09:32:45+00:00

Since ubifs-media.h is only used for ubifs-utils, move it under ubifs-utils/libubifs. Signed-off-by: Zhihao Cheng Signed-off-by: David Oberhollenzer

ubifs-utils: Adapt io.c in libubifs

2024-11-11T09:32:45+00:00

Adapt io.c in libubifs, compared with linux kernel implementations: 1. Modify io related functions(eg. ubifs_leb_read/ubifs_leb_write, etc.), adapt them with userspace io functions lseek/read/write. 2. Remove some functions(eg. record_magic_error, ubifs_bg_wbufs_sync) which won't be used in fsck/mkfs. 3. Replce ubifs_errc with ubifs_err, because there will be no SB_SILENT options in mkfs/fsck. 4. Initiate wbuf->size as c->max_write_size. Signed-off-by: Zhihao Cheng Signed-off-by: David Oberhollenzer

libubi: Add new interface ubi_leb_map()

2024-11-11T09:32:45+00:00

Add ubi_leb_map() implementation, it is used in UBIFS linux kernel libs. This is a preparation for replacing implementation of UBIFS utils with linux kernel libs. Signed-off-by: Zhihao Cheng Signed-off-by: David Oberhollenzer

mtd-utils: Extract rbtree implementation to common lib

2024-09-25T13:03:08+00:00

Current rbtree implementation code is put under jffs utils, extract it into common lib, and add more rbtree operations(eg. rb_first_postorder, rb_next_postorder, etc.). This is a preparation for replacing implementation of UBIFS utils with linux kernel libs. Signed-off-by: Zhihao Cheng Signed-off-by: David Oberhollenzer

mtd-utils: Extract list implementation to common lib and add list_sort support

2024-09-25T13:03:08+00:00

Current list implementation code is put under jffs utils, extract it into common lib, and add more list operations(eg. list_move, list_splice, etc.). Besides, add list sorting support in new source file lib/list_sort.c. This is a preparation for replacing implementation of UBIFS utils with linux kernel libs.

libubi: ubi_update_start: slightly improve documentation

2024-09-25T05:35:06+00:00

Calling ubi_update_start() may fail if exclusive access to the UBI volume cannot be established by the kernel. This is likely to happen if an UBI volume is updated directly after creation, because current versions of (systemd-)udevd run their internal 'blkid' also for UBI volumes as soon as they appear (trying to read the UBIFS UUID). There are mainly to options for this case: 1. Don't allow udevd to read UBI volumes at all (means loosing functionatlity) 2. Wait until udevd has finished accessing a new volume (requires cooperation with udevd) 3. Simply retry after short time in case of EBUSY For using option 3, the documentation should state that the concrete error code can be read via errno (this has always been the case since libubi has been introduced).

ubiattach: introduce need_resv_pool in UBI_IOCATT

2023-11-20T06:43:34+00:00

The ioctl UBI_IOCATT has been extended with need_resv_pool parameter in [1]. This parameter is used for deciding whether to reserve PEBs for filling pool/wl_pool for target ubi device. This parameter will be effective when fastmap is enabled, which will slow down the frequency of updating fastmap by filling more free PEBs in pool/wl_pool. See details in [2].
