driver core: dev_set_drvdata returns void

2019-05-03T15:55:22+00:00

dev_set_drvdata can no longer fail, so it could return void. All callers have hopefully been updated to no longer check for the return value.

vfio/pci: Fix integer overflows, bitmask check

2017-07-04T09:51:27+00:00

commit 05692d7005a364add85c6e25a6c4447ce08f913a upstream. The VFIO_DEVICE_SET_IRQS ioctl did not sufficiently sanitize user-supplied integers, potentially allowing memory corruption. This patch adds appropriate integer overflow checks, checks the range bounds for VFIO_IRQ_SET_DATA_NONE, and also verifies that only single element in the VFIO_IRQ_SET_DATA_TYPE_MASK bitmask is set. VFIO_IRQ_SET_ACTION_TYPE_MASK is already correctly checked later in vfio_pci_set_irqs_ioctl(). Furthermore, a kzalloc is changed to a kcalloc because the use of a kzalloc with an integer multiplication allowed an integer overflow condition to be reached without this patch. kcalloc checks for overflow and should prevent a similar occurrence.
