2019-05-20staging: vc04_services: prevent integer overflow in create_pagelist()Dan Carpenter1-0/+9
The create_pagelist() "count" parameter comes from the user in vchiq_ioctl() and it could overflow. If you look at how create_page() is called in vchiq_prepare_bulk_data(), then the "size" variable is an int so it doesn't make sense to allow negatives or larger than INT_MAX. I don't know this code terribly well, but I believe that typical values of "count" are typically quite low and I don't think this check will affect normal valid uses at all. The "pagelist_size" calculation can also overflow on 32 bit systems, but not on 64 bit systems. I have added an integer overflow check for that as well. The Raspberry PI doesn't offer the same level of memory protection that x86 does so these sorts of bugs are probably not super critical to fix.

2019-05-20staging: wlan-ng: fix adapter initialization failureTim Collier1-1/+2
Commit e895f00a8496 ("Staging: wlan-ng: hfa384x_usb.c Fixed too long code line warnings.") moved the retrieval of the transfer buffer from the URB from the top of function hfa384x_usbin_callback to a point after reposting of the URB via a call to submit_rx_urb. The reposting of the URB allocates a new transfer buffer so the new buffer is retrieved instead of the buffer containing the response passed into the callback. This results in failure to initialize the adapter with an error reported in the system log (something like "CTLX[1] error: state(Request failed)"). This change moves the retrieval to just before the point where the URB is reposted so that the correct transfer buffer is retrieved and initialization of the device succeeds.
