Revision 00b39f698a4f1ee897227cace2e3937fc4412270 authored by Stefan Haberland on 19 December 2019, 08:43:51 UTC, committed by Jens Axboe on 20 December 2019, 18:52:01 UTC
If for whatever reason the dasd_eckd_check_characteristics() function exits after at least some paths have their configuration data allocated those data is never freed again. In the error case the device->private pointer is set to NULL and dasd_eckd_uncheck_device() will exit without freeing the path data because of this NULL pointer. Fix by calling dasd_eckd_clear_conf_data() for error cases. Also use dasd_eckd_clear_conf_data() in dasd_eckd_uncheck_device() to avoid code duplication.

README
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.
