2021-11-17scsi: qla2xxx: Fix kernel crash when accessing port_speed sysfs fileArun Easi1-2/+22
commit 3ef68d4f0c9e7cb589ae8b70f07d77f528105331 upstream. Kernel crashes when accessing port_speed sysfs file. The issue happens on a CNA when the local array was accessed beyond bounds. Fix this by changing the lookup.

commit fb9024b0646939e59d8a0b6799b317070619795a upstream. Calling ql_log() inside qla2x00_port_speed_show() is causing messages to be output to the console for no particularly good reason. The sysfs read routine should just return the information to userspace. The only reason to log a message is when the port speed actually changes, and this already occurs elsewhere.

2017-08-31scsi: qla2xxx: Fix an integer overflow in sysfs codeDan Carpenter1-4/+4
The value of "size" comes from the user. When we add "start + size" it could lead to an integer overflow bug. It means we vmalloc() a lot more memory than we had intended. I believe that on 64 bit systems vmalloc() can succeed even if we ask it to allocate huge 4GB buffers. So we would get memory corruption and likely a crash when we call ha->isp_ops->write_optrom() and ->read_optrom(). Only root can trigger this bug.
