Subject: [PATCH 36/36] libparted: Remove fdasd geometry code from
|
|
alloc_metadata (#1244833)
|
|
|
|
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
|
|
(cherry picked from commit 9da2f460bebf9a8281fdd52536d3676b0914b8fd)
