* losetup: properly use --sector-size when create a new deviceKarel Zak2019-01-221-1/+3
| | | | | | | | | | | | | The --partscan functionality depends on sector size. Make sure sector size is set before we force kernel to scan the device for partitions. For example: losetup -f loopfile --sector-size 4KiB --partscan --show where 'loopfile' contains GPT with 4096 sectors.

* losetup: Add support for logical block sizeStanislav Brabec2017-09-271-0/+3
| | | | | | | | | | | | | | | | | | | | Kernel since 4.14 supports setting of logical block size[1]. It allows to create loop devices that report logical block size different from 512. Add support for this feature to losetup.

* losetup: add --nooverlap optionsKarel Zak2016-08-171-0/+11
| | | | | | | | | | | | | | | | | | | | | This patch introduces overlap detections and loop devices re-use for losetup(8). We already support this feature for mount(8) where it's enabled by default (because we mount filesystems and it's always mistake to share the same filesystem between more loop devices). Stanislav has suggested to enable this feature also for losetup by default. I'm not sure about it, IMHO it's better to keep losetup(8) simple and stupid by default, and inform users about possible problems and solutions in the man page. The feature forces losetup to scan all loop devices always when new one is requested. This maybe disadvantage (especially when we use control-loop to avoid /sys or /dev scans) on system with huge number of loop devices.

| | | | | | | | | | Also, for chcpu, the options -c, -d, -e and -g are mutually exclusive, and for the mode argument the option -p is not optional. For ldattach, use the standard options separator ", " instead of the unusual " | ". And add the missing --version to several of the pages. Besides, improve the wording and the consistency of the spacing. Signed-off-by: Benno Schulenberg <bensberg@justemail.net>

* mount: losetup: remove obsolete encryption supportLudwig Nussel2012-09-111-27/+2Star
| | | | | | | | | | | | | | | kernel cryptoloop is deprecated since ages and support for cryptoloop in util-linux is incomplete/broken. - no password hashing - last 8 bit of key are always set to zero - no binary keys possible (stops reading key at \n and \0) In the past some Distros added the above features with patches. So remove cryptoloop support from util-linux completely to make sure people won't try using it. Signed-off-by: Ludwig Nussel <ludwig.nussel@suse.de> Signed-off-by: Karel Zak <kzak@redhat.com>
