CVE-2024-45026

In the Linux kernel, the following vulnerability has been resolved:

s390/dasd: fix error recovery leading to data corruption on ESE devices

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.
