Colin Ian King	bbb7bace03	snic: correctly check for array overrun on overly long version number The snic version number is expected to be 4 decimals in the form like a netmask string with each number stored in an element in array v. However, there is an off-by-one check on the number of elements in v allowing one to pass a 5 decimal version number causing v[4] to be referenced, causing a buffer overrun. Fix the off-by-one error by comparing to i > 3 rather than 4.

snic: correctly check for array overrun on overly long version number

The snic version number is expected to be 4 decimals in the form like a
netmask string with each number stored in an element in array v.
However, there is an off-by-one check on the number of elements in v
allowing one to pass a 5 decimal version number causing v[4] to be
referenced, causing a buffer overrun.  Fix the off-by-one error by
comparing to i > 3 rather than 4.

snic: driver for Cisco SCSI HBA

Cisco has developed a new PCI HBA interface called sNIC, which stands for
SCSI NIC. This is a new storage feature supported on specialized network
adapter. The new PCI function provides a uniform host interface and abstracts
