[Bug 1640823] Re: [trusty] mount -o loop is limited to 8 loop devices

I successfully ran the test case against ubuntu20.9 in -proposed. I also verified that using losetup and mount on loop devices still works: $ sudo losetup -f --show debian-stretch-DI-alpha7-amd64-netinst.iso /dev/loop0 $ sudo mount /dev/loop0 /mnt mount: block device /dev/loop0 is

[Bug 1640823] Re: [trusty] mount -o loop is limited to 8 loop devices

This felt unusually risk to me, so I took a look at the patch before releasing. I found a number of problems: 1. This patch leaks a file descriptor every time the new code path runs. loop_ctl_fd is opened but not closed. 2. "int devnr = -1" is defined but never used. 3. > ll->ncur =

** Description changed: trusty has a very old util-linux which does not yet know about /dev /loop-control to create arbitrarily many loop devices. This feature was introduced in Linux 3.1 already (i. e. before precise even). This is a showstopper for backporting snappy as that needs a lot

[Bug 1640823] Re: [trusty] mount -o loop is limited to 8 loop devices

For the record: Commit 0b14bf7a is not sufficient. That neither fixes "losetup" nor "mount -o loop", and systemd's .mount units also just get translated into a /bin/mount -o loop" call. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu.
