ped_device_get_constraint: return constraint without alignment

In libparted-1.9 ped_device_get_constraint() would always return a constraint
without any start / end aligning (grain_size == 1). Now that we are starting to
support disks with a physical sector size other then 512, the old
ped_device_get_constraint() code may actually start returning constrains
with alignment info with a grain_size != 1.

alignment info into account, this patch removes the aligning code from
ped_device_get_constraint(), so that its behavior is unchanged.

it has actually done all these years.

15 years agolinux-commit: do not unnecessarily open partition device nodes

linux-commit: do not unnecessarily open partition device nodes

After patching parted with my do-not-use-BLKPG patch, I started
to get EBUSY errors on commit_to_os. Note this is not caused
by the do-not-use-BLKPG patch, this was already happening, but
parted was silently ignoring the errors (and the kernel was
not notified of the changes, which is bad).  The error now
actually gets reported.

The problem turns out to be in libparted/arch/linux.c's
_flush_cache function, which walks all the partitions of the
disk and does BLKFLSBUF calls on them.  This causes the following:

commit_to_os -> device_open -> fd = open /dev/sda ->
_flush_cache -> for each /dev/sda# open, ioctl, close
-> ioctl(fd, BLKRRPART) -> EBUSY

What is happening here is that the:
for each /dev/sda# open, ioctl, close

Is causing udev change events for all the /dev/sda#
nodes, which causes udev to call blkid on all these nodes
(on systems which use DeviceKit), so blkid has /dev/sda# nodes
open while BLKRRPART gets called on /dev/sda -> EBUSY.

I've checked with two independend storage subsystem kernel
developers, and /dev/sda and /dev/sda#, guarantee cache coherency
now-a-days.  So there is no need to do this for 2.6, which also
eliminates the need to call _flush_cache() on device open at all.

* libparted/arch/linux.c (_have_kern26): New function.
(_flush_cache): For linux kernels 2.6 and newer, don't flush
partition devices.
(linux_open): Skip _flush_cache on newer kernels here, too.

15 years agolinux-commit: remove the use of the BLKPG ioctl

linux-commit: remove the use of the BLKPG ioctl

While testing partitionable mdraid I noticed that the kernels
view of the partition table never changes even though I was successfully
making commit_to_os() calls.

This has let to me diving into libparted's commit_to_os() code for Linux
and there are multiple issues hiding in there:

1) Parted reads /sys/block/foo/range to determine how many partitions
   the device type supports and then makes BLKPG ioctl's to update the
   kernels view of the partition table for partitions which fall into
   this range. However for example /sys/block/sda/range contains 16,
   there are 2 issue with libparted using this number:
   1) scsi major's only support 15 partitions, 1 of the range of 16
      is reserved for the whole device, yet libparted will try
      to notify the kernel about 16 partitions if present
   2) If the major's partition minor's run out, the kernel will switch
      to the mdp major for the other partitions, iow range no longer
      limits the number of partitions.

2) libparted assumes the user knows what he is doing, and will ignore
   -ebusy errors for partitions, assuming that the user is smart enough
   to only change unused partitions. Parted does this without checking
   if the partitions which return ebusy actually are unchanged causing
   REAL errors to get unreported (BAD, really really BAD)

3) because of 1) libparted will only sync 1 partition on /dev/md#
   devices (would be 0 if not for the of by 1 bug as all md#p#
   partitions use the mdp major), and it fails to even do that without
   reporting an error.

###

1) we can fix by simply not checking /sys/block/foo/range, but instead
   just syncing max partitions.

2) is more troublesome, we could just make -EBUSY n error,
   but that may annoy / bug some users. OTOH in certain cases libparted
   already falls back to BLKRRPART which will return EBUSY so users
   should already be prepared to handle EBUSY

3) Could be fixed by making libparted recognize mdraid as a device type
   and except mdraid from using BLKPG, like it already is doing with
   DASD, but it might be better to just get rid of using BLKPG all
   together.  See below.

An even bigger problem IMHO is the use of the BLKPG ioctl instead of
BLKRRPART at all. What this does is tell the kernel parted's view
of the partition table and make it use that, instead of telling
the kernel to reread the partition table.  According to the parted
sources this is done for the case where the kernel does not know
the disklabel type. However as soon as the system is rebooted, the
system will be using the kernel's view. So IMHO it would be much
better to always use the kernels view and just always call BLKRRPART
in commit_to_os(), this would solve all of the above issues, *and*
make the way the system views the partition table consistent between
just after running parted and after a reboot.

I've attached a patch which removes the use of the BLKPG ioctl, notice
that this also removes a lot of special case code and workarounds,
which existence to me clearly indicates that using the BLKPG ioctl is
a bad idea.
