| | | | | | | | The option is unsupported since v2.23, let's cleanup man pages and code to remove it at all. Reported-by: "Dale R. Worley" <worley@alum.mit.edu> Signed-off-by: Karel Zak <kzak@redhat.com>

* losetup: don't require 512-byte aligned offsetsKarel Zak2013-10-011-5/+1Star
| | | | | | | | | | | | | | | | Kernel aligns the device size, but the offset where the device starts is not required to be aligned. # losetup --offset 32 -f file.img is just fine, the final size of the look device will be (in sectors) (backing_file_size - offset) >> 9 so we have to do the same in userspace when we check for successful set capacity ioctl.

* losetup: use loop-control to explicitly ask for deviceKarel Zak2013-08-061-0/+2
| | | | | | | | | | | | | | | | Now we use LOOP_CTL_GET_FREE ioctl to ask for free device, for example losetup -f foo.img Unfortunately, losetup(8) allows to ask for specified device losetup /dev/loop100 foo.img and in this case we assume that the device already exists in the system. This is incorrect, we should be able to use loop-control LOOP_CTL_ADD ioctl to ask for the specified device. Signed-off-by: Karel Zak <kzak@redhat.com>
* losetup: fix loop device name usageKarel Zak2013-08-051-4/+9
| | | | | | | | The code is not paranoid enough, loopcxt_set_device() only set the device name to loopdev struct, but it does not check if the device really exists. Signed-off-by: Karel Zak <kzak@redhat.com>
* losetup: make -j <path> more robustKarel Zak2013-08-051-10/+28
| | | | | | | | It's usually unnecessary as we compare devno and ino, but let's use absolute paths for situations when it's necessary to compare paths as strings. Signed-off-by: Karel Zak <kzak@redhat.com>

* loopdev: sync capacity after setting itJeff Mahoney2013-04-091-15/+4Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I recently tried to mount an hfsplus file system from an image file with a partition table by using the loop offset and sizelimit options to specify the location of the file system. hfsplus stores some metadata at a set offset from the end of the partition, so it's sensitive to the device size reported by the kernel. It worked with this: But failed with this: /dev/loop0: [0089]:2 (<imagefile>), offset 32768, sizelimit 102400000 /dev/loop1: [0089]:2 (<imagefile>), offset 32768, sizelimit 102400000 /proc/partitions shows the correct number of blocks to match the sizelimit. But if I set a breakpoint in mount before the mount syscall, I could see: 102400000 102432768 The kernel loop driver will set the gendisk capacity of the device at LOOP_SET_STATUS64 but won't sync it to the block device until one of two conditions are met: All open file descriptors referring to the device are closed (and it will sync when re-opened) or if the LOOP_SET_CAPACITY ioctl is called to sync it. Since mount opens the device and passes it directly to the mount syscall after LOOP_SET_STATUS64 without closing and reopening it, the sizelimit argument is effectively ignroed. The capacity needs to be synced immediately for it to work as expected. This patch adds the LOOP_SET_CAPACITY call to loopctx_setup_device since the device isn't yet released to the user, so it's safe to sync the capacity immediately.

* mount: losetup: remove obsolete encryption supportLudwig Nussel2012-09-111-23/+7Star
| | | | | | | | | | | | | | | 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>
