Subject: [PATCH] scsi: megasas: use appropriate property buffer size
|
|
|
|
When setting MegaRAID SAS controller properties via MegaRAID
|
|
Firmware Interface(MFI) commands, a user supplied size parameter
|
|
is used to set property value. Use appropriate size value to avoid
|
|
OOB access issues.
