[Bug 1788321] Re: swapon failed: invalid argument

[Roman Fiedler]

This is the failing "swapon" sequence from updated Xenial i386 on
vmware:

3915  open("/dev/sda2", O_RDONLY|O_LARGEFILE) = 3
3915  uname({sysname="Linux", nodename="v3ls1717", ...}) = 0
3915  ioctl(3, BLKGETSIZE64, [535822336]) = 0
3915  read(3, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 65536) = 65536
3915  close(3)                          = 0
3915  swapon("/dev/sda2", 0)            = -1 EINVAL (Invalid argument)

Sequence is identical to other, native/amd64 system with same kernel
version but without the problem where swapon() will return 0.

Title:
  swapon failed: invalid argument

Status in linux package in Ubuntu:
  Confirmed
Status in util-linux package in Ubuntu:
  Invalid

Bug description:
  Environment:
   - Ubuntu 18.04.1 LTS
   - Linux 4.15.0-32-generic i686

  Description:
  When I try to mount my swap partition or my swap file, I get "swapon failed: invalid argument" .

  Steps to reproduce:
  1) sudo bash
  2) dd if=/dev/zero of=/swapfile bs=1024 count=524288
  3) mkswap /swapfile
  4) chown root:root /swapfile
  5) chmod 0600 /swapfile
  6) swapon /swapfile
  Last execution returns "swapon failed: invalid argument" .

  I'm almost sure it's a bug because I have no problems using Linux
  4.15.0-29-generic instead of Linux 4.15.0-32-generic. Also, no
  problems using Ubuntu 18.04.1 LTS Live CD.

  Regards.
