Revision 7e76f34fa103677a27d96a7cfef8ce61389a32de authored by Aruna Balakrishnaiah on 08 August 2013, 17:03:49 UTC, committed by Benjamin Herrenschmidt on 09 August 2013, 08:06:40 UTC
When reading from pstore there is a buffer overflow during decompression due to the header added in unzip_oops. Remove unzip_oops and call pstore_decompress directly in nvram_pstore_read. Allocate buffer of size report_length of the oops header as header will not be deallocated in pstore. Since we have 'openssl' command line tool to decompress the compressed data, dump the compressed data in case decompression fails instead of not dumping anything.
