Subject: fdasd: geometry handling updated from upstream s390-tools
References: fate#320525 / bsc#935127
Patch-mainline: v3.3
Git-commit: 4d480d980a9b69b432b8d60df3c4397ba8cdc965
Remove the necessity for DASD-specific ioctls for partition handling.
This allows to correctly handle DASD-backed virtio block devices.
Note that this is necessary because virtio is just the transport.
A DASD, even if provided via virtio, still has it's unique
characteristics, which means that only traditional DASD partition
table formats can be used (no MBR, GPT, or similar).
Use bzero for initialization to make sure all struct members are
properly cleared. Also changed partition list handling code to be
more similar to upstream s390-tools fdasd.
Further, enhanced error handling capabilities by providing a
return code by fdasd_get_geometry.
Code is largely backported from s390-tools project.

Subject: dasd: enhance device probing
References: fate#320525 / bsc#935127
Patch-mainline: v3.3
Git-commit: 834713b5aee1edc004f863231dd489ee3a79f536
Probe for all device/transport types as every block device
could be a DASD on s390.
Since the calculation of the minimum and optimum alignment
is different between DASDs and common fixed block disks
we need a means other than dev->type == PED_DEVICE_DASD.
For that purpose a static function _ped_device_like_dasd()
offering a DASD detection heuristic has been added to
arch/linux.c.
By always providing arch-specific alignment functions the
need for DASD-specific code could be removed from device.c.
Observe fdasd_get_geometry return code for proper error
handling.
Remove the obsolete API check as we no longer require the
DASD-specific IOCTLs.

Fixes an issue with parted print being run against a logical
volume realised by extents on a physical volume residing on
a DASD.
We must make sure that geometry, device blocksize and DASD
attributes are present before we start format verifications
If any of it is missing this is not a DASD.

Subject: libparted: Remove fdasd geometry code from alloc_metadata
(#1244833)
References: fate#320525 / bsc#935127
Patch-mainline: v3.3
Git-commit: c58f816ffbc0bc4eacfb57d492cbe3b7497ede9f
commit db20944f changed how the trailing_metadata_end is calculated in
dasd_alloc_metadata, removing the need for setting up the anchor struct.
But dasd_alloc_metadata can be called in various contexts, and the
arch_specific->fd may or may not be valid during these calls. This can
result in unpredictable crashes when it uses a stale fd and tries to run
the file image code in fdasd_get_geometry instead of the device code.
The solution is to just drop the unneeded code, and to remember that
arch_specific->fd should only be used when ped_device_open has first
been called.
Resolves: rhbz#1244833

Subject: Add support for RAM drives
References: bsc#1006834
Patch-mainline: v3.3
Git-commit: 21131f62c6f508a5d0c080e025cf7db5df43fc7d
Recognize RAM drives, so "parted -s /dev/ram0 p" now prints
"RAM Drive (brd)" instead of "Model: Unknown (unknown)".
In order for a device to be recognized as RAM drive, it has to
have major number 1. Also the BLKFLSBUF ioctl shouldn't be used
on RAM drives as it is used to zero the device.
* NEWS: Mention the change
* include/parted/device.h.in(PedDeviceType): Add PED_DEVICE_RAM.
* libparted/arch/linux.c(RAM_MAJOR): New define.
* libparted/arch/linux.c(_device_probe_type): Recognize RAM drives.
* libparted/arch/linux.c(linux_new): Handle RAM drives.
* libparted/arch/linux.c(_flush_cache): Skip RAM drives.
* parted/parted.c(do_print): Add "brd" to list of transports.
