The first two fixes are workarounds for buggy IPMI hardware. The hardware says it has data for the IPMI driver to read constantly, so the driver reads the data constantly, causing any new requests to be blocked. The first fix was to check for invalid data right when the data was read from the device and stop the operation there (there was a later check for invalid data, but it could not stop the operation at that point). It turned out the device was providing good data, so that didn't fix the issue, but it's still a good check. The second fix stops fetching this data after a few fetches and allows other operations to occur. The driver won't work very well, but at least it won't wedge. This seems to fix the issue. The third issue is a problem I spotted while working on the previous issue where if a certain memory allocation failed the driver would stop working. The fourth issue is a problem was a missing set to NULL on a PTR_ERR() return, introduced in the previous series for 7.1. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE/Q1c5nzg9ZpmiCaGYfOMkJGb/4EFAmn4yl8ACgkQYfOMkJGb /4GWBw//Wt/Kqafokay7ke1t0O0SvJXljdOCPPQp159QiRlXhukxl/G3dxtecCJw 8oZb5fazuiYOaBllATt7vLa+0fKK7oJFNuRXnYqTggrX8RRkcLQVpt3S1MBIofwk gDeDKvw4TJcbvLfmGLtEnl/p37FddNHTS4rvtpynaqOmfHfq/3MiXPYYqLjOiGPG EiH89viNZspiSlhAl3iMPXWkkVlW72r9kVn+YASDgL2+z5C+qZPA+Us0fxpVw02n qwHBW39RgbhS3uRKnveDSoUm8VIr7/brp14ph6m2YlNxAnZQtyG5Ul8s3NCneQFJ zr8HrTnl6gAl7SKYliOJXKpGGmpzwDKnqGnnh9IIaQAJZnblNhCsGM2oLw/d0ySe O3pxvpyVN1ETPgv7NubDxlRTfc+XuX8soCQq3KSyj2gj700+NKW4CSAZHSLj7xW2 95JTsWFcUDWFi8fpc/p1PX7rgnB1KAWVQWdOWleUuQValeUjNpBdl5Yn34fqbVDG DAYlkzXWXpszynfd3QxiwAUlYEeTyue+UZf8plVR+Gw3OwN3fGbFCBZOcVD4S8aA w6ihk5eWR05dP2JgPBv9IxDHt+kY6/2o2qQEFow/0nYZIJGZI1IQPBWZi5ux7ygB Cduro3EkzqkP9t42zavhWMxYagtpqyUOhuLFkWEZlMrdB2hNAVA= =jA6/ -----END PGP SIGNATURE----- Merge tag 'for-linus-7.1-2' of https://github.com/cminyard/linux-ipmi Pull IPMI fixes from Corey Minyard: "Fix a number of issues that came up recently The first two fixes are workarounds for buggy IPMI hardware.
