2017-05-08ubifs: Add CONFIG_UBIFS_FS_SECURITY to disable/enable security labelsHyunchul Lee
When write syscall is called, every time security label is searched to determine that file's privileges should be changed. If LSM(Linux Security Model) is not used, this is useless. So introduce CONFIG_UBIFS_SECURITY to disable security labels. it's default value is "y". Signed-off-by: Hyunchul Lee <cheol.lee@lge.com> Signed-off-by: Richard Weinberger <richard@nod.at>
2017-01-17ubifs: add CONFIG_BLOCK dependency for encryptionArnd Bergmann
This came up during the v4.10 merge window: warning: (UBIFS_FS_ENCRYPTION) selects FS_ENCRYPTION which has unmet direct dependencies (BLOCK) fs/crypto/crypto.c: In function 'fscrypt_zeroout_range': fs/crypto/crypto.c:355:9: error: implicit declaration of function 'bio_alloc';did you mean 'd_alloc'? [-Werror=implicit-function-declaration] bio = bio_alloc(GFP_NOWAIT, 1); The easiest way out is to limit UBIFS_FS_ENCRYPTION to configurations that also enable BLOCK.

2015-11-07ubifs: introduce UBIFS_ATIME_SUPPORT to ubifsDongsheng Yang
To make ubifs support atime flexily, this commit introduces a Kconfig option named as UBIFS_ATIME_SUPPORT. With UBIFS_ATIME_SUPPORT=n: ubifs keeps the full compatibility to no_atime from the start of ubifs. =================UBIFS_ATIME_SUPPORT=n======================= -o - no atime -o atime - no atime -o noatime - no atime -o relatime - no atime -o strictatime - no atime -o lazyatime - no atime With UBIFS_ATIME_SUPPORT=y: ubifs supports the atime same with other main stream file systems. =================UBIFS_ATIME_SUPPORT=y======================= -o - default behavior (relatime currently) -o atime - atime support -o noatime - no atime support -o relatime - relative atime support -o strictatime - strict atime support -o lazyatime - lazy atime support Signed-off-by: Dongsheng Yang <yangds.fnst@cn.fujitsu.com> Reviewed-by: Richard Weinberger <richard@nod.at> Signed-off-by: Richard Weinberger <richard@nod.at>

2011-04-05UBIFS: do not select KALLSYMS_ALLArtem Bityutskiy
All UBIFS needs is to make sure we stacktraces when UBIFS debugging is enabled. It is enough to select KALLSYMS for this, KALLSYMS_ALL is not necessary. Moreover, Randy Dunlap reported that UBIFS causes the following Kconfig dependency warning: warning: (UBIFS_FS_DEBUG && LOCKDEP && LATENCYTOP) selects KALLSYMS_ALL which has unmet direct dependencies (DEBUG_KERNEL && KALLSYMS) The reason is that KALLSYMS_ALL requires DEBUG_KERNEL and KALLSYMS, so ideally, to select KALLSYMS_ALL we'd need to select DEBUG_KERNEL and KALLSYMS first. This seems to be too much to select. The easiest way to go is to forget about KALLSYMS_ALL and just select KALLSYMS when UBIFS debugging is enabled - that should be enough for stackdumps.

2011-03-24UBIFS: kill CONFIG_UBIFS_FS_DEBUG_CHKSArtem Bityutskiy
Simplify UBIFS configuration menu and kill the option to enable self-check compile-time. We do not really need this because we can do this run-time using the module parameters or the corresponding sysfs interfaces. And there is a value in simplifying the kernel configuration menu which becomes increasingly large. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-03-11UBIFS: simplify UBIFS Kconfig menuArtem Bityutskiy
Remove debug message level and debug checks Kconfig options as they proved to be useless anyway. We have sysfs interface which we can use for fine-grained debugging messages and checks selection, see Documentation/filesystems/ubifs.txt for mode details.

2010-03-07Revert "lib: build list_sort() only if needed"Linus Torvalds
This reverts commit a069c266ae5fdfbf5b4aecf2c672413aa33b2504. It turns ou that not only was it missing a case (XFS) that needed it, but perhaps more importantly, people sometimes want to enable new modules that they hadn't had enabled before, and if such a module uses list_sort(), it can't easily be inserted any more. So rather than add a "select LIST_SORT" to the XFS case, just leave it compiled in. It's not all _that_ big, after all, and the inconvenience isn't worth it.
