2013-05-13lib/loopdev: fix loopcxt_check_size() to work with blkdevsKarel Zak1-1/+15
The loopcxt_check_size() is workaround for kernels < v3.9, kernel has been fixed by commit 541c742a7559eb65f0e36d3e2338c2ca532a3e61. The function sets loopdev size according to backing file size. The problem is that the backing file could be a block device where stat.st_size is zero, so we have to use blkdev_get_size() for block devices.

2013-04-09loopdev: sync capacity after setting itJeff Mahoney3-6/+85
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.

2013-02-14unshare,nsenter: spawn shell by defaultZbigniew Jędrzejewski-Szmek2-1/+29
The behaviour mimics chroot. Possibly it would have been nicer to to query the password database in the new namepace and run the shell of the user there, but it's hard to do correctly. getpwuid() might need to load nss plugins, and the arch in the new namespace might be different (in case of NEWNS mounts), or the hostname might be different, etc. So in general it's not possible to do it reliably.
