Alasdair Kergon
85d2c49d14 Some ioctl code tidying: removing duplicate internal buffers; making bounds 
checks clearer (incl. variable renaming); using a flag to indicate when
output data doesn't fit into supplied buffer instead of returning an error etc.

dd2157534b Default stripesize 64k & config file setting for it; 
Clear many compiler warnings (i386) & associated bugs - hopefully without
introducing too many new bugs:-)  (Same exercise required for other archs.)
Default compilation has optimisation - or else use ./configure --enable-debug

95bd5605a8 Improve missing-kernel-driver error message. 2002-11-01 16:16:42 +00:00
Alasdair Kergon
51da710f5a o Long-awaited ioctl interface clean-up. *** Not backwardly compatible *** 
o Various other kernel side tidy-ups.
o Version number changes so we have the option of adding new ioctl commands
  in future without affecting the use of existing ones should you later
  revert to an older kernel but not revert the userspace library/tools.
o Better separation of kernel/userspace elements in the build process to
  prepare for independent distribution of the kernel driver.

569d69b3d2 o Knock the version check out of the makefile, Alasdair will no doubt put it back :) 
o  Change to new ioctl names.

b0277370cf o dm_destroy_all() called on exit - but doesn't touch suspended devices yet. 
o 'dmsetup remove_all' calls dm_destroy_all() to provide a quick way to
  prepare for unloading the module
o Ran through indent again.

ed6a860fad Add function that returns the library version. 2002-01-17 14:13:25 +00:00
Alasdair Kergon
423e579292 Add another level of symlink to library name (like LVM1) so people who find 
themselves running multiple incompatible kernel versions will just need
to swap symlinks at boot.
 2002-01-17 13:37:09 +00:00

ee11aa9e75 Use additional version numbers. 
Kernel driver has a version number (stored in kernel/VERSION).
  The first two components of this (0.94) give the version number of the
  ioctl interface.  This number must be changed whenever a change is
  made to the ioctl interface that breaks backwards compatibility.

  The library has a version number (stored in VERSION) which is
  used for linking.
  The first and/or second component of this must be changed whenever
  a change is made to the library API that breaks backwards
  compatibility.

ed1b3a023c Another ioctl interface update: 
Supply offset to start of variable data area (so struct size can change
without breaking backward compatibility)
  Add command that just returns the driver version
 2002-01-15 15:21:57 +00:00

49588ccd98 Some ioctl interface changes. (Do we want these?) 
- use status bits (so we can add flags without changing the struct size)
  - use dev_t
 2002-01-14 23:07:32 +00:00
Alasdair Kergon
74c67fbf4b o Add rename support to dmsetup. 
o Add support to use specified minor number to library and dmsetup.
