Stefan Haberland 93a7e28569 s390/dasd: fix error recovery leading to data corruption on ESE devices
commit 7db4042336 upstream.

Extent Space Efficient (ESE) or thin provisioned volumes need to be
formatted on demand during usual IO processing.

The dasd_ese_needs_format function checks for error codes that signal
the non existence of a proper track format.

The check for incorrect length is to imprecise since other error cases
leading to transport of insufficient data also have this flag set.
This might lead to data corruption in certain error cases for example
during a storage server warmstart.

Fix by removing the check for incorrect length and replacing by
explicitly checking for invalid track format in transport mode.

Also remove the check for file protected since this is not a valid
ESE handling case.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
